Sinonasal involvement as a rare extraintestinal manifestation of Crohn's disease.

Crohn's disease is a chronic idiopathic slowly developing transmural inflammation of the digestive system. It usually involves the small intestine and/or the area around the anus but can also affect the entire gastrointestinal tract anywhere from the mouth to the anus. Extra intestinal manifestations occur frequently and multiple organ systems may be affected: the skin, joints, spine, eyes, liver and bile ducts. In contrast, nasal manifestations are extremely rare and only a few cases have been reported up to date in the worldwide literature. The authors report two cases with nasal manifestations concomitant to intestinal Crohn's disease and go over the relevant literature on such an association.

Management of chronic rhinosinusitis without polyps in adults.

Chronic Rhinosinusitis (CRS) is a group of multifactorial diseases characterised by inflammation of the mucosa of the nose and paranasal sinuses with a history of at least 12 weeks of persistent symptoms and signs despite maximal medical therapy. IgE-mediated hypersensitivity and asthma are the two most important associated factors. Diagnosis of CRS is based upon the medical history and either an endoscopy or CT scan. Initial medical treatment usually consists of the avoidance of all the contributory factors and then nasal douching and nasal steroids. If medical treatment fails, endoscopic sinus surgery is considered. The authors review the most important factors associated with CRS, the diagnostic work-up and different treatment options. They also present a rationale for treatment.

Facial pain from visceral origin.

INTRODUCTION: Unilateral facial pain in the trigeminal area is known to be caused by a cancer in the superior lobe of the lung. CASE REPORT: A 65 year old male, heavy smoker, presented a permanent otalgia and a mandibular pain on the left side. These symptoms could not be relieved by common analgesics. All explorations for common etiologies were negative. After an episode of dyspnea, a left lung cancer was discovered. Thanks to radiotherapy and chemotherapy, the patient's pain was improved. CONCLUSION: Referred facial pain is rare and can be explained by the invasion of the tenth nerve by an upper lobe lung tumor. In most cases, the patient presents a right otalgia and pain in the area of V3. The diagnosis can be delayed from 1 month to 4 years after the onset of the pain. Referred facial pain is improved by the treatment of the causal lung cancer.

Nasal dermoid cyst: diagnosis and management of five cases.

Five cases of nasal dermoid cyst are presented. Three out of five cases were settled during childhood. Three presented a mass with a hole on the external nose with recurrent local infections. One case was wrongly referred for a dacryocystitis. The first one was detected during an infection of the cerebral extension and frontal abscess was assessed by CT scan and MRI. Two patients had other associated congenital abnormalities: hypotrophy of the external ear in one case, multiples malformations in an other. Adequate exposure and cosmetic results are sometimes contradictory to define the best surgical approach. Dermoid cysts and sinuses must be completely removed to prevent recurrence. External rhinoplasty and bicoronal approach are the main procedures for removing these lesions.

Congenital nasal pyriform aperture stenosis in newborn: report on three cases.

Congenital nasal pyriform aperture stenosis (CNPAS) is recognized as a cause of nasal airway obstruction in the newborn. The nasal pyriform aperture is narrowed by a bony overgrowth of the nasal process of the maxilla. The CNPAS may occur as an isolated congenital defect or in combination with other abnormalities. Three cases of CNPAS are reported with special attention to the clinical presentation and to the management recommendation prior to surgery. Surgical repair was performed for all these three highly symptomatic patients using a sublabial approach for drilling the nasal process in order to obtain a wider nasal vestibular patency. All of them were equipped with bilateral nasal stenting.

Endoscopic endonasal surgery for paranasal sinus mucoceles.

Paranasal sinus mucoceles are benign, space-occupying, cystic lesions that require a surgical treatment. An endoscopic endonasal marsupialisation is nowadays the surgical approach of choice in most of the cases. The aim of the present study is to validate this option and to determine the clinical characteristics of paranasal sinus mucoceles. A retrospective study based on the clinical experience of several ENT surgeons was performed using a standardised questionnaire. The respondents participate to a report on endoscopic endonasal surgery for non-inflammatory disease in Belgium. One hundred and fourty patients presenting 178 mucoceles were included in this study. Primitive mucoceles were reported in 35% of the patients, posttraumatic mucoceles in 2.1% and postoperative mucoceles in 62.9%. The time interval between first rhinologic procedure and the mucocele diagnosis was respectively 24.4 months after FESS and 108.3 months after an external procedure. Paranasal sinus mucoceles predominantly occur in the fronto-ethmoidal region (64%), followed by the maxillary sinus (18.6%), the sphenoid sinus (8.4%) and the posterior ethmoid sinus (6.7%). Uncommon locations were also reported in 2.3% (Inferior turbinate, middle turbinate, pterygomaxillary space). Endoscopic endonasal marsupialisation (combined with an external procedure for 8 patients) was successful in 97.9% of the patients. Only 3 patients showed recurrence. Endoscopic endonasal marsupialisation of paranasal sinus mucoceles is a reliable therapeutic option with favorable results and is supported by the questioned ENT surgeons in Belgium.

EES in rare benign tumors.

Endoscopic Endonasal Surgery (EES) can successfully be carried out for benign tumors such as osteomas, benign vascular tumors, pituitary adenomas, pneumoceles and benign fibrous tumors. This report concerns a Belgian perspective documenting our experience in 49 such cases. Among them are 33 cases of pituitary adenoma. Thanks to the experience accumulated in the surgical management of inflammatory sinusal disease, these tumors were able to be removed, totally or partially, under endoscopic guidance with the aid of powered endoscopic instrumentation, and in some cases, CO2 laser fiber. Advantages are well-known; lower cost, shorter stay in hospital, lower morbidity, lower cosmetic or functional disabilities. We emphasize the need for the surgeon to be able to switch the endoscopic procedure to an external one if difficulties occur or the tumor is more extensive than expected.

Pneumoceles of the paranasal sinuses (a case report).

We report a case of an infection of a large sphenoidal sinus communicating with a hyperaerated mastoid. Endoscopic drainage of this large cavity was successful. We suggest that EES should have a place in the treatment of the sinusal pneumocele. Surgery should however be reserved for cosmetic purposes, infection, algetic symptoms and ocular problems. A cosmetic correction with osteotomy and bone resection can be associated with the endoscopic surgery.

Surgery of inverted papillomas under endoscopic control.

Six centers cooperated in a retrospective study on endoscopic surgical resection of Papillomas of the nose and paranasal sinuses in order to assess both the efficiency and the safety of this kind of surgical approach. From 1991 till march 2000, 87 cases of Papillomas resections under--at least partially--endoscopic control were gathered, among which 85 were Inverted Papillomas (IP), 2 were Exophytic Papilloma (EP) and one was IP coexisting with Collumnar Cell Papilloma (CCP). Malignant transformation was found out in 3 cases of IP. Regarding the 85 patients with IP demographics are as follows: 61 males, 24 females, with a mean age of 58.4 years (STDV: 13.96) in a range from 27 to 92 years. The mean follow-up was of 41.9 months with range of 1-120 months. Fifteen recurrences occurred that were treated by revision surgery either under endoscopic control or by limited external approach. The mean time for recurrences to occur was 8.07 months with range of 1-24 months. The three patients with malignant transformation underwent postoperative radiation therapy. All of the patients are free of recurrence, however for some of them the follow-up is too short to definitely assess their free of disease status. The role of modern diagnostic tools in medical imaging--CAT and MRI--in order to assess clearly the limits of the tumors and to enhance the efficiency and the safety in the choice of a surgical approach is pointed out. The stress is put on the need for radical excision under endoscopic control which can be combined with the Caldwell-Luc transantral approach or with frontal trepanation for the cure of tumors impossible to be reached under endoscopic control only. Irrespective of the tumor extent and of the approaches that was used for excision a close endoscopic follow-up still remain mandatory, by trained surgeons, in the long term management of IP. Biopsies, CAT and/or MRI must be performed in any case with recurrence suspicion.

Intranasal endoscopic surgery in traumatic optic neuropathy--the Belgian experience.

The management of traumatic optic neuropathy remains controversial. In this report we present the results of 8 patients treated by means of an intranasal endoscopic approach to the optic canal after at least 12 hours of corticosteroid therapy without improvement. Vision improved in four of the eight patients who underwent the surgery. There was no morbidity or mortality. As the results of the endoscopic optic nerve decompression are comparable to those reported using other surgical procedures, we feel that this approach merits consideration by surgeons.

Endoscopic endonasal surgery (EES) in skull base repairs and CSF leakage.

This report aims to summarise the current role of Endoscopic Endonasal Surgery (EES) for skull base and cerebrospinal fluid (CSF) leakage repair, to provide some guidelines for the clinical diagnosis and technical procedures of repair, to demonstrate the limits of this approach and to discuss the Belgian experience of the recent years. Endoscopic surgery for chronic sinus disease is being performed with increasing frequency and CSF leak is an significant potential complication of this surgery, although the incidence of osteo-meningeal perforations in endonasal sinus surgery is below 1% overall. CSF leakage bears the risk of meningeal or intracranial infection and complication and therefore should be repaired as soon as recognised. Following proper localisation of the leak, repair is safely performed in most of the cases by endonasal route with the help of free mucoperiostal flaps taken from the inferior or middle turbinates. This also applies for lesions of other aetiologies. The Belgian data support the statement that the endonasal endoscopic approach is a suitable and successful technique to close CSF leaks in the vast majority of our patients.

Endoscopic endonasal surgery in choanal atresia.

Twenty-seven cases of choanal atresia operated between 1979 and 2000 have been reported from 4 different institutions (19 females, 8 males, age of first surgical procedure ranging from 2 days to 35 years). Of these 27 cases, 22 were previously untreated. The outcomes for 19 of these new cases were available for the present report. Bilateral atresias were somewhat more frequent (15 versus 12) and associated anomalies were present in 10 out of 27 patients. Details about the types of atresia, associated anomalies, surgical techniques, duration of stenting and outcomes are given together with a theoretical review on choanal atresia.

Endoscopic sinus surgery for juvenile nasopharyngeal angiofibroma.

Juvenile nasopharyngeal angiofibroma is a rare tumour of the head and neck with very specific characteristics: adolescent males, choana-nasopharynx, pterygomaxillary fossa widening, specific and intense vascularisation. Staging is very important in the decision of the surgical approach. Endoscopic management of juvenile nasopharyngeal angiofibroma is technically possible after preoperative embolisation. Up to now 13 angiofibroma have been treated using the endonasal endoscopic sinus surgery approach in Belgium (Leuven 8; Mont-Godinne 2; Ghent 1; Liege 1; Woluwe 1). In smaller tumors endoscopic resection has been successful in four cases without any recurrence. Five larger tumors, extending in the pterygomaxillary fossa, were also successfully resected. Extension into the infratemporal fossa or the cavernous sinus can be endoscopically removed, but recurrences may occur as they do after classical, external approaches. In conclusion, the endoscopic approach is an acceptable alternative in small to middle sized juvenile nasopharyngeal angiofibroma.

Minimally invasive endoscopic management of malignant sinonasal tumours.

A large retrospective study from two belgian institutions of 78 patients who underwent minimally invasive endoscopic management for malignant sinonasal tumors from, 1992-1999 is presented. We attempt to assess the results of this less invasive approach. The spectrum of disease included adenocarcinoma, squamous cell carcinoma, olfactory neuroblastoma and other malignant tumors. All patients were treated primarily for cure. 66 patients were operated on by a purely endoscopic technique, while 9 patients had a simultaneous neurosurgical and endoscopic approach, and 3 a limited orbital approach. 16 patients (20.5%) presented with local recurrence, 6 patients (7.7%) sustained distant metastases and 7 patients (9%) presented simultaneous local recurrence and distant metastases. The 2-years and 5-years survival rates of the whole group were respectively 73.1% and 52.3%, while the adenocarcinoma group exhibits a significantly better prognosis than other histological types with 2-years and 5-years survival rates of 89.8% and 63.8%. Patients who could be treated purely endoscopically had a significantly better survival in comparison to patients treated by an external and endoscopic approach. Morbidity was minimal and the local control rate as well as survival rates were comparable to literature data. Endoscopic resection was adequate, providing clear margins and en bloc removal in most cases. Our results encourage us to use this minimally invasive approach in selected cases as a reliable alternative to the systematic use of an exclusively external approach.

Humoral immunodeficiency in recurrent upper respiratory tract infections. Some basic, clinical and therapeutic features.

Adequate surface protection of the upper airway tract depends on intimate co-operation between natural non specific defence mechanisms such as ciliary function and acquired adaptative immunity. The latter is mediated by specific antibodies mainly belonging to secretory immunoglobulin A (SIgA) and to lesser extent secretory IgM (SigM) as well as by serum derived and locally produced IgG. Immunoglobulin's deficiency may exist in a significant percentage of patients with chronic or recurrent infections of the upper respiratory tract. So an immunologic screening should be extended to patients who have persistent sinus infection, despite normal mucocilary and ventilation patterns, inadequate response to antimicrobial therapy, culture of unusual pathogens from the upper respiratory tract or history of infection at other side, mainly bronchopulmonary. The therapeutic aspects include immunoglobulin replacement or mucosal immunogens whose efficacy is related with both an unspecific and a specific way. In the future, cytokines will probably become the strongest therapy of the immunoglobulin's deficiency.

Comparison of the efficacy, safety, and onset of action of mizolastine, cetirizine, and placebo in the management of seasonal allergic rhinoconjunctivitis. MIZOCET Study Group.

BACKGROUND: Mizolastine is a potent and selective H1-receptor antagonist with additional anti-allergic properties. OBJECTIVE: The aim of this European multicenter, randomized, double-blind study was to compare the efficacy of mizolastine 10 mg (n = 122), cetirizine 10 mg (n = 125), and placebo (n = 128) once daily for 28 days in patients with seasonal allergic rhinoconjunctivitis (SAR), with focus on the onset of action. METHODS: Symptoms were evaluated by the investigator using a total symptom score (TS) and by the patient (first week). Responders (R) were patients with a TS decrease of at least 50%. Safety was assessed according to the spontaneous reporting of adverse events. RESULTS: Both mizolastine and cetirizine were effective in relieving the symptoms of SAR. After 7 days of treatment, the improvement in TS and responder's rate were significantly (P < .05) greater in patients treated with mizolastine (TS change versus baseline, mean +/- SD: -6.40 +/- 5.71; R: 55%) and cetirizine (TS change versus baseline: -6.24 +/- 5.24; R: 53%) than with placebo (TS change versus baseline: -4.11 +/- 5.91; R: 40%). Both drugs acted rapidly, within 2 hours of the first intake. During the first 3 days, mizolastine relieved symptoms more effectively than cetirizine, the difference being significant on the second (P = .027) and third (P = .050) day. Both mizolastine and cetirizine were well tolerated. CONCLUSION: Mizolastine 10 mg once daily is at least as effective as cetirizine in relieving symptoms of SAR, onset of action is rapid with clinical effect evident within 2 hours.

Endoscopic manifestations of Wegener disease.

The diagnostic criteria for upper airway necrotizing diseases such as Wegener's granulomatosis (WG) are well defined. However, the differentiation with other diseases of unknown aetiology remains difficult. Establishing an early diagnosis and prompt treatment is very important to minimize loss of function and cosmetic deformity. In the last fifteen years, we observed and treated eight cases of WG. In six patients, WG appeared primarily in the nose area. One patient presented primarily middle ear and secondary nose involvement, whereas in one case, the inner ear was affected too. One patient did not present nasal involvement although the middle ear and several cranial nerves were involved. For these patients, the pathognomonic diagnosis had not been confirmed by biopsy at the early stage and we introduced an immunosuppressive therapy on the basis of clinical and histological findings only. For the eight patients, the treatment stopped the disease process but for one patient, we abandoned drugs because of side effects. Finally, only four of the cases only had a pathognomonic histological diagnosis of WG. In four cases, serologically anticytoplasmic antibodies against neutrophil granulocytes (Anca) were observed early. Both clinical and histological findings and determination of these antibodies give the possibility to solve difficulties in WG differential diagnosis.
