Fibrous dysplasia of middle turbinate associated with Widal syndrome: endoscopic treatment of a rare case.
Fibrous dysplasia, a rare bony disease, is characterised by substitution of normal bone with immature tissue embedded in a fibrous stroma. It can be either monostotic or involve several bones. Fibrous dysplasia is usually asymptomatic but, in the advanced stage, pain due to neural compression or pathological fractures may occur. In the case of cranio-facial involvement, ocular, masticatory, respiratory or auditory functional alterations are possible. A case of fibrous dysplasia, limited to the middle turbinate and associated with Widal triad (sinus-nasal polyposis, asthma, acetyl salicylic acid intolerance), is described. Craniofacial computed tomography revealed enlargement of left middle turbinate with characteristic "ground-glass" appearance. The patient underwent anterior bilateral functional endoscopic sinus surgery with near-total resection of left middle turbinate. Histopathological examination confirmed the diagnosis of fibrous dysplasia. After 2 years the patient is still asymptomatic. Videorhinoscopy shows good sinus-nasal patency without disease recurrence. Even though exceptional, localization of fibrous dysplasia at middle turbinate has been described, therefore, it must be considered in the differential diagnosis of the craniofacial ossifying disorder. For localized and symptomatic lesions, endoscopic surgery is an effective option. Scrupulous life-long follow-up is necessary due to the high percentage of recurrence and possible malignant degeneration.

Contact laser surgery in treatment of vocal fold paralysis.
Vocal fold paralysis is a pathological condition characterised by varying degrees of respiratory distress in relation to the degree of glottic stenosis. Dyspnoea may be present even when resting and may even require emergency tracheotomy. Frequently, the patient arrives for attention after the onset of exertional dyspnoea associated with a certain degree of dysphonia. The causes may be central or peripheral, more commonly iatrogenic following thyroid or tracheal surgery or secondary to injury. The aim of all surgical techniques used in the treatment of vocal fold paralysis is to restore a lumen sufficient to guarantee adequate breathing through the natural airway, without the patient having to permanently maintain the tracheotomy tube, while preserving acceptable phonatory quality. Between 1990 and 2001, at the Padua Hospital Unit of Endoscopic Airway Surgery, 48 patients (27 female, 21 male) were treated for respiratory distress secondary to vocal fold paralysis. At the beginning of this experience, 7 patients underwent arytenoidectomy with the Ossoff technique. In 34 cases, a modified Dennis-Kashima posterior cordectomy was performed. In 7 patients, since widening of the airway was necessary, cordectomy was extended to the false homolateral chord in 5 cases and to the arytenoid vocal process in another 2. In 9 patients, the operation was carried out with a Nd Yag (1064 nm) contact laser; the remaining 39 were treated with a GaArAl (810 nm) diode laser in use since 1995. Satisfactory results were obtained in all patients first treated by us and not already tracheotomised (35). In 23 cases (66%), results were considered "good" since no exertional dyspnoea occurred. In 12 patients (34%), the result was considered "sufficient" since there was no resting dyspnoea and normal everyday activity could be undertaken. Of the 13 patients already tracheotomised on arrival, 11 (85%) were decanulated on average 2 months after surgery. In conclusion, the present results show that endoscopic posterior cordectomy, performed by contact diode laser, gives reliable results, is rapid and simpler to perform than arytenoidectomy and guarantees a sufficient airway without impairing swallowing, while maintaining entirely acceptable voice quality.

Tailored approach to Zenker's diverticula.
BACKGROUND: Zenker's diverticula (ZD) can be treated by diverticulostomy or open surgery (upper esophageal sphincter myotomy and diverticulectomy or diverticulopexy). The aim of this study was to compare the outcome of the two alternative treatments. METHODS: Fifty eight patients were scored for symptoms and upper esophageal sphincter (UES) pressure; relaxations and intrabolus pressures were recorded by manometry. Treatment depended on operative risk and ZD size. Twenty four patients with high surgical risk and/or a <3-cm or >5-cm pouch underwent diverticulostomy; the other 34 had open surgery. RESULTS: Mortality was nil. Five patients had postoperative complications after open surgery (p<0.05). Hospital stay was shorter after diverticulostomy (p<0.001). Follow-up (41 months; range, 1-101) was obtained in 53 patients. Postoperative manometry showed a UES pressure reduction, improved UES relaxation, and lower intrabolus pressure in both groups (p<0.05). In the diverticulostomy group, three patients complained of severe dysphagia. vs none in the open surgery group (p<0.05). CONCLUSION: Diverticulostomy is safe, quick, and effective for most patients with medium-sized ZD, but open surgery offers better long-term results and should be recommended for younger, healthy patients with small or very large diverticula.

Functional approach to infants and young children with noisy breathing: validation of pneumotachography by blinded comparison with bronchoscopy.
Flow-volume loop evaluation yields considerable diagnostic information about adult patients with upper airway obstruction. No conclusive data support the reliability of this method in young children with noisy breathing. We used analysis of flow-volume loops at tidal breathing (TB-FV) as a first diagnostic approach to young children presenting with persistent noisy breathing (chronic stridor and/or wheezing). Flexible fiberoptic bronchoscopy was performed to establish a conclusive diagnosis and was used to verify the accuracy of the preliminary functional localization of the airway obstruction causing noisy breathing. The physician conducting pneumotachography was blinded to the bronchoscopic findings in the study, and the investigators conducting bronchoscopy were blinded to the pneumotachographic findings. Through a 6-yr period, 113 consecutive young children (ranging in age from 15 to 48 mo) with noisy breathing were enrolled in the study. Three morphologically abnormal TB-FV patterns, as compared with the normal round-shaped TB-FV loops obtained with 15 healthy children, were identified in 110 patients. A TB-FV pattern of inspiratory fluttering was found in 26 subjects and in the first 3 yr of the study was always associated with an endoscopic diagnosis of isolated laryngomalacia. Subsequently, this pattern was used to diagnose isolated laryngomalacia in 18 other infants, in whom endoscopy was avoided. Of infants with endoscopic evidence of airway obstruction ranging from the glottis to the mainstem bronchi (49 subjects), all but three showed a TB-FV loop pattern characterized by expiratory-limb flattening. A concave expiratory loop, with early expiratory peak flow and low flow at low volume, was invariably associated with peripheral bronchoconstriction, without endoscopic evidence of anatomic abnormalities (20 cases). In conclusion, TB- FV loop analysis is a noninvasive, accurate method of establishing the site of airway obstruction in young children with recurrent stridor and/or wheezing. Clinical use of this method may provide interesting pathophysiologic information and may be useful in addressing the diagnostic management of such children.

[Post-intubation subglottal stenosis in children: risk factors and prevention in pediatric intensive care].
BACKGROUND: Endotracheal intubation (EI) may result in significant injury to the larynx and trachea; subglottic stenosis is the most dangerous consequence of this injury in the pediatric age. It is well known that there are potential risk factors for post-intubation subglottic stenosis, and namely the underlying disease requiring EI, the age and body weight at EI, the duration and number of EI, the absence of sedation and the occurrence of infectious, hypotensive or hypoxic events during the period of EI and the traumatic EI. On the basis of our data an attempt is made to understand which factors are more important in the pathogenesis of this complication and whether post-intubation subglottic stenosis is a preventable complication of EI in children. METHODS: The clinical records of 32 out of 35 children with post-intubation subglottic stenosis referred to our institution because of this complication in the period 1990-1997 (8 years) have been examined. Three children were excluded from the study because of partial data. Our surgical division is specialized in the diagnosis and the management of pediatric laryngotracheal diseases. The diagnosis was confirmed by videolaryngotracheoscopy under general anesthesia and by computerized tomography or magnetic resonance imaging in 10 children whose tracheal stenosis was critical. The degree of the stenosis was determined according to Cotton's classification. RESULTS: The analysis of our data confirms that post-intubation subglottic stenosis is a more frequent complication in infants and particularly in low birth weight infants. It occurred after long lasting EI, but after short lasting EI too. Many of the children observed had their trachea intubated several times during their illness and many EI were traumatic. Sedation during EI was only seldom took into account by pediatric intensivists. CONCLUSIONS: Prevention of post-intubation subglottic stenosis is possible through a better management of the EI and of the child with a tracheal tube. Sedation of intubated children and skill in the EI technique and in the tube size selection are very important. Many intubations can be avoided with a better attention to the tube fixation and to extubation criteria. Some children at high risk for this complication can be identified.

Benign tracheoesophageal fistula: results of surgical therapy.
Acquired fistulas between the trachea and the esophagus (TEFs) are unusual, serious and still challenging clinical entities. Between 1980 and 1997, 31 patients with acquired benign TEF were evaluated and treated in our department. The definitive treatment was undertaken when patients were weaned from the ventilator. Dissection of the fistula and closure of the tracheal and esophageal defect was performed in 26 patients. Esophagogastroplasty plus closure of the tracheal defect and omental interposition was performed in two patients. Tracheal resection and reconstruction plus of the sternocleidomastoid muscle interposition was carried out in one patient with circumferential tracheal damage. In two patients, no surgical treatment was carried out. One patient died after surgical treatment. In 23 patients, long-term follow-up was excellent, with normal post-operative function of both the esophagus and the airway. Two failures of treatment occurred which required definitive tracheostomy plus T-tube. Management of TEFs can be safely carried out after weaning patients from the ventilator.

Endoscopic diverticulotomy for the treatment of Zenker's diverticulum: results in 102 patients with staple-assisted endoscopy.
Endoscopic diverticulotomy for the treatment of Zenker's diverticulum has been reported infrequently in the literature and has engendered considerable controversy. Between March 1992 and September 1996, we attempted to treat 102 patients with endoscopic treatment for pharyngoesophageal diverticula. In 98 patients, the endoscopic surgery was successfully completed. Conversion to open surgery was required in 4 patients (3.92%). One cartridge of staples in 16 patients (16.32%), 2 cartridges in 78 patients (79.59%), and 3 cartridges in 4 patients (4.08%) were used, according to the size of the diverticulum; the median duration of the procedure was 20 minutes (10 to 60 minutes). No postoperative morbidity or mortality was recorded. Oral feeding was started following radiologic control after a median of 2 days; the median hospital stay was 4 days. The median follow-up is 16 months (1 to 45 months). Four patients operated on before the introduction of the modified stapler showed a persistent diverticular pouch: 3 underwent repeat endoscopic operation, and 1 underwent conventional open surgery. All treated patients are asymptomatic. Manometric study performed in 15 patients showed a significant reduction of basal upper esophageal sphincter pressure compared to preoperative data (48.30+/-21.74 versus 29.38+/-5.68 mm Hg; p<.01). We therefore recommend endoscopic diverticulotomy, considering that the procedure is relatively safe and effective, with minimal patient discomfort, and the results are equal to those of the external approach. This procedure offers the advantages of short hospitalization, rapid convalescence, brief operative time, absence of skin incision. predictable resolution of symptoms, and reduced morbidity.

Cranial and cervical nerve injuries after carotid endarterectomy: a prospective study.
BACKGROUND: The purpose of this study was to review the outcome of patients who had cranial and cervical nerve injuries after carotid endarterectomy (CEA). METHODS: This prospective study reviewed 200 consecutive CEAs. Preoperative and postoperative cranial nerve assessment was completed on all patients. Neurologic evaluation included routine direct fiberoptic laryngoscopy. Patients found to have no neurologic injury had no further follow-up. Patients with postoperative peripheral neurologic dysfunction were enrolled for regular long-term follow-up to assess delayed recovery. RESULTS: Overall, 25 (12.5%) nerve injuries were identified in 24 patients. There were 11 (5.5%) hypoglossal, 8 (4%) recurrent laryngeal, 2 (1%) superior laryngeal, 2 (1%) marginal mandibular, and 2 (1%) greater auricular nerve injuries. None of the patients were lost to follow-up. All nerve dysfunctions were transient, with all but 4 nerves recovering completely within 6 months. The recovery took from 1 week to 37 months, with a mean recovery time of 5.8 months. Two patients with recurrent laryngeal nerve dysfunction were found to have prolonged full recovery time (i.e., 31 and 37 months, respectively). Two patients successfully underwent contralateral CEA, although movement of the opposite vocal cord was not fully restored. CONCLUSIONS: Cranial nerve injury after CEA is a common occurrence and can be classified as a "major" or "minor" complication, depending on the severity of the clinical consequences. Extended follow-up will identify the specific subset of patients with a late complete nerve recovery.

Minimally invasive surgery for Zenker diverticulum: analysis of results in 95 consecutive patients.
OBJECTIVE: To assess the effectiveness of transoral stapled diverticulum esophagostomy in relieving symptoms and decreasing outflow resistance at the pharyngoesophageal junction in patients with Zenker diverticulum. DESIGN: Cohort study. From April 1, 1992, until May 31, 1996, the operation was attempted in 95 patients. The median follow-up was 23 months (range, 13-48 months). SETTING: Tertiary care university hospital. PATIENTS: There were 74 men and 21 women, with a median age of 64 years (age range, 37-92 years). All complained of dysphagia and pharyngo-oral regurgitation, and 18 (20%) suffered from recurrent aspiration pneumonia. The median size of the pouch measured by flexible endoscopy was 4 cm (range, 2.5-8 cm). INTERVENTION: The septum between the diverticulum and the esophageal lumen was divided under general anesthesia using a linear endostapler introduced through a Weerda endoscope. In most patients, 2 applications of the endostapler with a modified anvil were used. Operative time averaged 23 minutes. MAIN OUTCOME MEASURES: Morbidity, symptom score, patient's satisfaction, videofluorographic barium transit, hypopharyngeal intrabolus pressure, upper esophageal clearance of radioisotope. RESULTS: A switch to open surgery was required in 3 patients (3.1%), due to difficult exposure of the common wall in 2 cases and a mucosal tear in the other. No postoperative morbidity or mortality was recorded. Oral feeding was started the following day and the median hospital stay was 3 days (range, 2-8 days). Five patients complained of persistent symptoms; 3 of them underwent another endosurgical operation, 1 underwent laser treatment by means of flexible endoscopy, and 1 eventually required open surgery. All patients are asymptomatic at the latest follow-up visit. Postoperative radiologic studies showed free flow of barium in all patients. Manometry showed a significant reduction of hypopharyngeal intrabolus pressure over preoperative values (P=.003). Radionuclide studies showed a significant reduction of upper esophageal residual activity at 1 minute compared with preoperative values (P=.006). CONCLUSIONS: Endosurgical approach to hypopharyngeal diverticula larger than 2 cm is safe and effective. Symptom relief, elimination of the pouch, and decreased outflow resistance at the pharyngoesophageal junction can be obtained without morbidity and with a short hospital stay.

[The treatment of choanal atresia].
Choanal atresia occurs in approximately 1 out of every 8000 live births. In about 60% of these cases it is unilateral and is often associated with other major craniofacial anomalies or visceral malformations such as the so-called CHARGE syndrome (i.e. Choloboma, Heart defects, choanal Atresia, Retarded growth and development, Genital anomaly, and Ear defect with deafness) first described by Pagon in 1981. In newborns the clinical manifestations of choanal atresia consist of respiratory distress strictly related to the entity of nasal obstruction. Total bilateral congenial choanal atresia must, therefore, be considered a surgical emergency since nasal obstruction impedes the suction mechanism and hence normal feeding in the newborn. For this reason, prompt surgery is mandatory. The surgical approach employed in choanal atresia consists of both the trans-nasal and trans-palatal approaches. Between 1985 and 1997 31 patients with choanal atresia were treated in our department (16 males, 15 females; age range 2 days-5.5 years; mean 11.4 months). In 25 cases (80.6%) the malformation was bilateral. Associated anomalies were seen in 8 patients (25.8% of cases). All of these patients were treated using the trans-nasal approach, under general anesthesia, and endoscopic control. In 27 cases a trocar was employed to perforate the bony atresia and a stent was then positioned. Three patients underwent contact-laser resection of the stenosis without requiring any further stent and without any complications. None of these patients developed total recurrences, although after varying amounts of time, in 8 of the 27 patients operated using the trocar (29.6% of cases) a partial reduction of the airway occurred, the substenosis requiring dilatation with progressive Hegar dilators. In the remaining cases contact-laser therapy was associated with dilation. Three of the patients were treated by laser-therapy alone and none developed a recurrence. One patient dropped out of the follow-up for other serious malformations.

Endoscopic dilation of acquired tracheobronchial stenosis in infants.
Acquired tracheobronchial strictures in infants are associated with significant morbidity. Their treatment requires different types of therapeutic procedures depending on the severity and location of the stenosis. We successfully dilated five children (ages between 1 and 23 months) with acquired tracheobronchial (stenoses two carinal and three of the mainstem bronchi) using a new technique. Gruentzig balloon catheters of different caliber were introduced into the tracheal lumen of apneic children under endoscopic vision. Three infants required four dilations and in the other two cases only two procedures were necessary. One complication occurred during dilation and resulted in a pneumothorax caused by a partial-bronchial disruption. At follow-up (range, 18-36 months; mean, 23.4 months) all five children were clinically improved. In the four cases without complications the chest x-rays were normal and the last bronchoscopy showed tracheobronchial trees with normal calibers. The child who developed a pneumothorax during attempted dilation recovered. In this child, dilation of the right upper lobe bronchus was unsuccessful. Dilation was attempted without visualization of the bronchus and the stricture. Our limited experience confirms that pneumatic balloon catheters can successfully treat acquired tracheobronchial stenoses in infants. To avoid complications, strict criteria need to be applied in the selection of cases with tracheobronchial stenoses.

[Benign laryngotracheal stenoses in pediatric age].
The diagnosis and treatment of infants and children with laryngo-tracheal pathology has changed substantially over the last 20 years. The change is the result of the continued evolution of diagnostic instruments, surgical techniques and new advancements in critical care medicine. Abnormalities in the development of the larynx may lead to congenital subglottic stenosis. A variety of pathogenic processes, either inflammatory or iatrogenic, also may damage the cricoid cartilage and lead to subglottic stenosis. The stenosis may involve alone or in combination the subglottis, glottis, upper cervical trachea. In this article the author reports a 12 years experience in 114 patients affected by benign laryngo-tracheal stenosis. These patients are classified in two groups: 1) 75 patients with congenital stenosis, 2) 39 patients with acquired stenosis. For the diagnose video-endoscopy has been used, and for the classification the Cotton's technique has been used. To get the best results in this pathology it is very important to have a multidisciplinary approach.

Fistular complication of gastric ectopia in the proximal oesophagus and pyriform sinus.
Gastric ectopias in the upper oesophagus and hypopharynx are relatively rare and often misinterpreted. They may become symptomatic due to the onset of a fistula involving adjacent structures in the neck. This case report describes a 20-year-old patient with swallowing difficulties and laterocervical pain, with a diagnosis of fistula of the pyriform sinus due to secernent gastric mucosal ectopia. The significance of this case lies in the fact that accurate aetiopathogenic study and careful differential diagnostic procedures enabled the proper identification of this rare upper oesophageal pathology, which is often misdiagnosed due to the technical difficulties involved in conventional endoscopy of the digestive tract.

The safety of home tracheostomy care for children.
Home tracheostomy care avoids prolonged hospitalization for tracheostomized children who must remain cannulated for a long time; however the safety aspects of this form of management are still under discussion. Since 1987 the authors have tutored parents in tracheostomy care. Once parental training was complete and the necessary equipment (aspirator, humidifier, etc) provided, children in stable condition were discharged and had period follow-up as outpatients. Thirty-four children had a total of 710 months in home care; 11 of them had decannulation. The only reported complications were two partial obstructions of the cannula and two accidental decannulations. The low number of documented accidents and the parents' profound appreciation in having their children at home indicate that patients with a tracheostomy in need of long-term care can be safely managed at home.

[Surgical emergency in thyroid disease: acute respiratory failure caused by tracheal obstruction].
Diagnostic and therapeutic approach to emergency due to acute and severe respiratory compromise by thyroid goiters with tracheal obstruction is discussed. Such an alarming condition was observed in 5 (2.3%) out of 215 mediastinal goiters operated between 1967-91. Retrospective and critical analysis of these cases pointed out that preventive removal of a large goiter is the best prophylaxis; first management is not surgical, although urgent features. Admission to intensive care center and endotracheal intubation allow an adequate interpretation of the pathologic condition and operative troubles and risks. Diagnostic investigations, effective and kept to a minimum (chest x-ray, tracheo-laryngoscopy, TAC), must be carried out without delaying thyroidectomy and prolonging intubation for days. The extraction of goiter is nearly always performable by the cervicotomic way. Whenever necessary endotracheal intubation obviates the need of tracheostomy for solving transient postoperative complications such as laryngeal oedema, local hematoma and recurrent nerves stupor.
