Postobstructive pulmonary edema after laryngospasm in the otolaryngology patient.
CONTEXT: Post-obstructive pulmonary edema (PPE) is an uncommon complication which develops immediately after the onset of acute airway obstruction such as laryngospasm or epiglottitis (type I) or after the relief of chronic upper airway obstruction such as adenotonsillar hypertrophy (type II). OBJECTIVE: To describe the development of type I PPE following laryngospasm in pediatric and adult patients undergoing otolaryngologic surgical procedures other than those for treatment of obstructive sleep apnea. DESIGN: Retrospective case series of 13 otolaryngology patients from 1996 to 2003. SETTING: Tertiary care teaching hospital and its affiliates. PATIENTS: 13 patients (4 children, 9 adults, 5 males, 8 females) ranging in age from 9 months to 48 years. RESULTS: Operative procedures included adenoidectomy, tonsillectomy, removal of an esophageal foreign body, microlaryngoscopy with papilloma excision, endoscopic sinus surgery, septorhinoplasty, and thyroidectomy. Six patients required reintubation. Treatment included positive pressure ventilation, oxygen therapy, and diuretics. Seven patients were discharged within 24 hours and the others were discharged between 2 and 8 days postoperatively. There were no mortalities. CONCLUSION: Laryngospasm resulting in PPE may occur in both children and adults after various otolaryngologic procedures. Among the subgroup of children, our study is the first to report its occurrence in healthy children without sleep apnea undergoing elective surgery.

Age as a prognostic factor for complications of major head and neck surgery.
OBJECTIVE: To determine if age alone is a prognostic indicator of surgical outcomes for major head and neck procedures. DESIGN: Retrospective cohort study over a 4-year period. SETTING: Academic referral center, institutional practice, hospitalized care. PATIENTS: Included in this study were patients who had undergone ablative, reconstructive, and other major surgical procedures of the head and neck, including neck dissection, laryngectomy, maxillectomy, thyroidectomy with lymphadenectomy, and composite resection of the oral cavity with reconstruction, for both malignant and benign disease. MAIN OUTCOME MEASURES: Patient data and intraoperative and postoperative course factors were recorded. Comorbidity was graded using an Adult Comorbidity Evaluation 27 test, Charlson Comorbidity Index, and American Society of Anesthesiology score. Postoperative complications were dichotomized, and multiple logistic regression was used for data analysis. RESULTS: Medical chart review identified 157 cases. Analysis of data revealed that time under general anesthesia was the only factor consistently related to complications (P<.006), and it was the only factor consistently related to length of stay (P<.001). Analysis of major complications (6% incidence) as an outcome using univariate analysis resulted in a strong positive correlation with both comorbidity indexes: Adult Comorbidity Evaluation 27 (P = .002) and Charlson Comorbidity Index (P = .005). Multiple logistic regression showed no significant relationship between age 70 years or older (20% of patients) and either complications or hospital length of stay. CONCLUSIONS: Patient's age alone is not a prognostic indicator of surgical outcome for major head and neck procedures. However, comorbidity is an important predictive factor for postoperative complications in any age group. Time under general anesthesia showed a statistically significant relationship with complication rate and hospital length of stay in multivariate analyses. Consequently, prevention of complications should focus on optimizing preoperative comorbid conditions.

Endoscopic management of anterior skull base tumors.
Anterior craniofacial resection has become a standard procedure for management of lesions of the anterior skull base. During the last 2 decades, modifications of the classic anterior craniofacial resection have been reported. With the introduction of endoscopic sinus techniques and instrumentation, surgeons have begun to use endoscopic approaches for management of anterior skull base lesions. This article describes endoscopic modifications of anterior craniofacial resection.

Endoscopic transnasal transsphenoidal pituitary surgery--comparison with the traditional sublabial transseptal approach.
The technique of endoscopic transnasal, nontransseptal, transsphenoidal pituitary surgery is gaining increasing popularity. Many pituitary surgical teams consider it the procedure of choice. It provides a rapid and safe approach to the sella turcica. Within the sella turcica, the endoscopes give the surgeon the ability to inspect around the corner and to remove residual tumor. The procedure avoids the complications related to the sublabial transeptal approach. Hospital stay is shorter.

Carcinoma of the oropharynx: factors affecting outcome.
OBJECTIVES/HYPOTHESIS: To assess the value of both patient- and tumor-related factors of oropharyngeal squamous cell carcinoma in predicting patient outcome, with respect to the three primary subsites of the disease. It was hypothesized that the subsite has a significant impact on outcome. STUDY DESIGN: Historical cohort study. METHODS: A chart review was conducted of 126 patients diagnosed with squamous cell carcinoma of the oropharynx over a 10-year period. The oropharynx was divided into the following subsites: 1) base of tongue, 2) tonsil and pillars, and 3) uvula, soft palate, and posterior pharyngeal wall. Patient-related factors included age and gender. Tumor-related factors included American Joint Committee on Cancer stage, T stage, N stage, and grade. These factors were compared using the end points of disease-free survival and treatment response (complete response or partial response/no response). RESULTS: Tumor-related factors such as American Joint Committee on Cancer stage (P = .016) and T stage (P = .008) had a significant impact on treatment response. The American Joint Committee on Cancer stage (P = .030) and the T stage (P = .005) were also significant predictors of disease-free survival. Base-of-tongue lesions responded significantly worse to treatment than did tonsil and pillar or uvula, soft palate, and posterior pharyngeal wall lesions (P = .014). The disease-free survival for base-of-tongue cancer was significantly worse than for tonsil and pillar or for uvula, soft palate, and posterior pharyngeal wall cancer (P = .010). CONCLUSION: Patient-related factors such as age and gender were not significant in predicting disease-specific outcome. Important tumor-related factors were the American Joint Committee on Cancer stage and the T stage. Among the oropharyngeal subsites, squamous cell carcinoma of the base of tongue was associated with the worst outcome.

Combined endoscopic transmaxillary-transnasal approach to the pterygoid region, lateral sphenoid sinus, and retrobulbar orbit.
OBJECTIVES: The sublabial transmaxillary approach to the pterygoid region was a popular one during the Caldwell-Luc, pre-endoscopic era. It was the procedure of choice for management of lesions of the pterygopalatine space, for internal maxillary artery ligation, and for vidian neurectomy. With the introduction of endoscopic instrumentation and techniques, the Caldwell-Luc procedure is rarely performed today. Also, because vidian neurectomy is performed less frequently, and because internal maxillary artery ligation for severe epistaxis has been replaced with transnasal endoscopic sphenopalatine artery ligation, the sublabial transmaxillary route is rarely used. We have found that combining the use of endoscopes via the sublabial approach and the transnasal endoscopic approach is very helpful for management of extreme lateral lesions of the sphenoid sinus, as well as the pterygoid region and the posterior orbit. METHODS: The records of patients who underwent a combined endoscopic transmaxillary-transnasal approach between 1994 and 2002 were reviewed. Indications for the procedure included extreme lateral sphenoid and pterygoid encephalocele (3 patients), pterygoid mucocele (2 patients), orbital apex lesion (2 patients), and pterygopalatine tumor (2 patients). RESULTS: Nine patients underwent the above-mentioned procedure. Wide and comfortable exposure of the involved region was achieved in all cases. Compared with the transnasal approach, the working distance, working comfort, and maneuverability of instruments were significantly enhanced. There were no major complications related to the approach. Because the maxillary wall opening is very small, infraorbital hypoesthesia is very limited and of short duration. CONCLUSIONS: Combining the transmaxillary and transnasal approaches for endoscopic management of pterygoid, lateral sphenoid, and retrobulbar orbit lesions provides excellent exposure and avoids the limited working angle and surgical struggle that may be associated with the use of the transnasal approach alone.

Recurrence rates after endoscopic sinus surgery for massive sinus polyposis.
BACKGROUND AND OBJECTIVES: Most studies on outcome after endoscopic sinus surgery (ESS) include patients with varying degrees of disease severity. Recurrence rates cited by those studies may not apply to the subset of patients with severe polyposis. Our aim is to provide reference information for recurrence rates and need for revision surgery in patients with severe disease. STUDY DESIGN, PATIENTS, AND METHODS: Review of patients with severe polyposis with a minimum Lund-McKay score of 16 and with a Kennedy computed tomography stage 3 or 4. Data collection included demographics, presence of asthma or documented allergy, history of previous surgery, extent of surgery, preoperative and postoperative management, recurrence rates, revision surgery rates, and follow-up. RESULTS: One hundred and eighteen records were reviewed. Fifty-nine (50%) patients had asthma, and 93 (79%) had documented allergy. All patients required extensive bilateral nasal polypectomy, complete anterior and posterior ethmoidectomy, and maxillary sinusotomy. One hundred (85%) also had frontal or sphenoid sinusotomy. Follow-up ranged from 12 to 168 (median 40) months. Seventy-one (60%) developed recurrent polyposis. Fifty-five (47%) were advised to undergo revision surgery, and 32 (27%) underwent surgery. History of previous sinus surgery or asthma predicted higher recurrence (P <.005, P <.001) and revision surgery rates (P =.02, P <.001). History of allergy also predicted recurrence and need for revision (P <.001, P <.001). CONCLUSIONS: Recurrence rates after ESS for severe polyposis are significant. In our study, patients with asthma are at higher risk of recurrence.

Tracheal resection with end-to-end anastomosis for benign tracheal stenosis.
To review our experience with tracheal resection with end-to-end anastomosis for tracheal stenosis, we performed a retrospective review at a tertiary-care academic medical center. Twenty-eight patients underwent circumferential tracheal resection with end-to-end anastomosis by 2 attending otolaryngologists from 1989 to 2002. Patients were excluded if they were under 12 years of age or if the surgical indication was tracheal or thyroid neoplasm. The indications for tracheal resection were postintubation stenosis (n = 9; 32%), posttracheotomy stenosis (n = 7; 25%), both postintubation and posttracheotomy stenosis (n = 9; 32%), external tracheal trauma (n = 2; 7%), and presence of a foreign body (n = 1; 4%). Two to 8 rings were resected. The follow-up periods ranged from 18 months to 13.5 years. The anastomotic success rate was 89% (n = 25). No patients died as a result of the procedure. We conclude that tracheal resection with end-to-end anastomosis is a relatively safe and reliable procedure for the treatment of tracheal stenosis in appropriately selected patients.

Partial laryngectomy with imbrication laryngoplasty for glottic carcinoma.
BACKGROUND: Treatment options for unilateral glottic carcinoma include radiation therapy, partial laryngectomy, and endoscopic cordectomy. We used partial laryngectomy with imbrication laryngoplasty (PLIL) for definitive treatment with curative intent in a select group of patients. STUDY DESIGN: Retrospective multicenter review of 24 patients treated with PLIL. Data collection included demographics, tumor characteristics, time to decannulation, time to oral food intake, local control, survival, voice result as judged by the physician, voice result as judged by the patient, and patient satisfaction. SETTING: Five academic medical centers. METHODS: PLIL includes a composite resection of the entire vocal fold, with its ligament, muscle, adjacent paraglottic tissues, and the adjacent block of thyroid cartilage. A neocord is reconstructed by imbricating the remaining thyroid cartilage strips and covering them with a false vocal fold flap. RESULTS: A total of 24 patients (T1, n = 13; T2, n = 10; and T3, n = 1) underwent PLIL. Median time to decannulation was 4 days, and median time to oral food intake was 5 days. Clear margins were achieved in 23 patients (96%). Follow-up ranged from 1 to 11 years (median duration of follow-up, 5.5 years). In the patients who had clear margins at the initial surgery, the rate of overall disease control was 100%. Voice quality was judged by the physician as good or excellent in 100% of the patients who underwent PLIL, and as better than typical hemilaryngectomy in 23 patients (96%). Twenty-three patients (96%) were satisfied with their voice quality. CONCLUSIONS: PLIL provides us with a single modality curative approach to unilateral glottic carcinoma. It also provides rapid recovery of oral and/or nasal airway and swallowing, excellent voice quality, and a disease-control rate similar to or better than other treatment modalities.

Endoscopic Craniofacial Approach for Intracranial Polyposis: The "Blue-Sky Technique"
Massive sinonasal polyposis associated with skull base dehiscence and intracranial extension is a difficult disease to treat. Conventional transnasal or transfacial techniques can result in dural injury, cerebrospinal fluid (CSF) leak and infection. We describe our experience with a combined neurosurgical-endoscopic technique that protects the meninges. Five patients with massive sinonasal polyposis extending intracranially through skull base dehiscence were reviewed retrospectively. The minimum follow-up was 2 years. A frontal craniotomy was performed through a bicoronal approach. The dura was carefully separated from all infectious material at the floor of the anterior cranial fossa. The frontal lobe with the intact meninges was elevated off the anterior cranial floor. A sheet of blue plastic material was inserted under the frontal lobe from the craniotomy site to the planum sphenoidale. Next, a transnasal endoscopic ethmoidectomy, sphenoidectomy, and frontal sinusotomy were performed to remove the inflammatory processes. The blue plastic material was visible through any existing or potential skull base dehiscence, thus providing visual protection for the dura and brain. All gross disease was removed from the frontal, ethmoid, and sphenoid skull base regions in the 5 patients without dural injury. None of the patients developed a CSF leak or meningitis. Two patients developed recurrent polyposis limited to the sinuses without intracranial extension. The endoscopic craniofacial approach with the "Blue-Sky" protective technique offers a safe method for completely removing massive sinonasal polyposis associated with an intracranial extension.

The Wookey flap revisited.
BACKGROUND: Complete circumferential pharyngoesophageal reconstruction has undergone remarkable changes and developments during the last three decades. Gastric transposition and microvascular techniques are the standards of care. However, in cases of failure, or where other factors such as severe comorbidities prevent the use of microvascular techniques, reconstruction with local flaps provide a reliable option. We have used the Wookey flap technique in six patients with complete circumferential loss of the pharynx and upper esophagus. To make the procedure more reliable, we added a "delay" stage. METHODS: Retrospective review of charts of six Wookey-type reconstructions of the pharynx and upper esophagus done in our department at SUNY-HSC, Brooklyn, and The Long Island College Hospital. RESULTS: Five of the six patients had successful reconstruction of complete circumferential pharyngoesophageal resection. All five resumed oral alimentation. The flap failed in one patient. CONCLUSIONS: The Wookey flap may still provide surgeons with a "last resort" reconstructive option after complete, circumferential pharyngoesophageal resection.

Laryngeal chondroma.
Cartilaginous tumors of the larynx represent less than 1% of laryngeal tumors. Chondroma and "low-grade" chondrosarcoma are the most common; 70%-75% of these tumors arise on the endolaryngeal surface of the posterior lamina of the cricoid cartilage. The clinical presentation is varied and directly dependent on the size and location of the tumor; stridor, hoarseness, dyspnea, or a neck mass are common presenting signs. CT scanning in the axial plane is the mainstay of radiographic imaging due to its ability to show size, extent of the tumor, and invasion into surrounding structures. Surgical extirpation is the standard therapy with no role for radiation therapy or chemotherapy. Although significant recurrence rates have been reported, there is not a significant difference between initial conservative therapy followed by salvage therapy versus initial radical therapy.

Temporoparietal osteofascial flap for head and neck reconstruction.
PURPOSE: This article describes the use of the temporoparietal osteofascial flap (TOF) for reconstruction of bony defects in the midface and mandible. PATIENTS AND METHODS: We reviewed the demographics, etiology, indications, surgical technique, radiographic evaluation, and final outcome of 11 patients with upper or lower jaw defects who underwent reconstruction using the TOF between 1994 and 1999. RESULTS: The TOF was used to reconstruct a defect of the mandible in 7 patients, the hard palate in 2 patients, the maxilla in 1 patient, and the zygoma in 1 patient. The defect was a result of tumor resection in 9 patients and of trauma in 2 patients. The defect size ranged from 3 to 6 cm. Ten flaps (91%) were successful and 1 flap failed. There was 1 donor site complication (small dural tear) that was repaired immediately without sequelae. One patient had osseointegrated dental implants placed in the bone with good results. Exploration of the construction area was performed in 1 patient 13 months after surgery because of recurrent tumor. It showed a fully integrated bone flap. CONCLUSION: This vascularized calvarial bone flap can be used for the reconstruction of small to medium-sized defects of the maxilla and lateral mandible with good functional and cosmetic results. It can be performed without special microvascular expertise and with minimal donor site morbidity. A full-thickness bone flap can support osseointegrated dental implants.

Midfacial degloving approach for repair of naso-orbital-ethmoid and midfacial fractures.
OBJECTIVE: To demonstrate that the midfacial degloving (MFD) approach can provide the proper exposure to successfully reduce naso-orbital-ethmoid (NOE) and midfacial fractures while eliminating the need for external skin incisions. DESIGN: A retrospective review of patients with NOE and concomitant midfacial fractures that were repaired via the MFD approach for exposure. SETTING: Tertiary care academic medical center. METHODS: The MFD approach was used to access NOE and concomitant midfacial fractures for repair in 9 patients with facial trauma. Physical examination and imaging studies were used for preoperative evaluation. Functional and cosmetic results were assessed during follow-up with serial physical examinations and postreduction films. RESULTS: No significant technical problems were encountered in the treatment of NOE and concomitant fractures, which included 5 Le Fort I, 1 Le Fort II, 1 Le Fort III, 6 orbital rim (1 superior, 4 inferior, and 1 lateral), and 4 zygomatic complex fractures. Physical examination and imaging studies showed adequate reduction in all patients, and all patients were satisfied with their short- and long-term functional and cosmetic results. CONCLUSION: The MFD approach can provide the necessary exposure to properly reduce NOE and midfacial fractures without the need for external skin incisions.
