Predictive Factors for Efficacious Oral Appliance Therapy in Moderate to Severe Obstructive Sleep Apnea Patients.

Objectives/hypothesis: Oral appliances (OAs) are a treatment for obstructive sleep apnea hypopnea syndrome (OSAHS). The main objective of the study was to determine the predictive factors of OA efficacy. The secondary objective was to measure the efficacy rates and determine OAs' tolerance and dropout.

Objectives: To describe an extensive pseudotumor as a complication of stapes surgery.

Methods: Radiological workup and surgical exploration in a 38-year-old man suffering from postoperative hearing loss. The patient presented with tinnitus, inferior facial palsy, vertigo, and rapidly progressive hearing loss after his operation.

Intracellular residency is frequently associated with recurrent Staphylococcus aureus rhinosinusitis.

Aim: The prevalence of intracellular Staphylococcus aureus organisms in the nasal mucosa of patients with recurrent infectious rhinosinusitis episodes was studied.

Method: Twenty-seven consecutive adult patients who failed medical management of chronic rhinosinusitis (CRS) of multiple origins, associated or not with nasal polyposis, were consecutively enrolled for endonasal sinus surgery (including partial middle turbinectomy, middle antrostomy, ethmoidectomy, sphenoidotomy) and followed for a 12-month post-operative period.

Results: Seventeen of these patients showed the presence of intracellular S.

Prevalence of lymph nodes in the apex of level V: a plea against the necessity to dissect the apex of level V in mucosal head and neck cancer.

Background: We assessed the prevalence of histologically proven normal or invaded lymph nodes in the apex of level V.

Methods: Seventy neck dissections were performed in 41 patients with mucosal head and neck squamous cell carcinoma (SCC). Fifty-one neck dissections were performed in 30 previously untreated patients (group 1); 19 neck dissections were carried out in 11 patients previously irradiated (group 2).

Subtotal carbon dioxide laser arytenoidectomy for the treatment of bilateral vocal fold immobility: long-term results.

Sixty-nine patients underwent subtotal carbon dioxide laser arytenoidectomy for treatment of bilateral vocal fold immobility between 1985 and 2000. The population included 69 patients whose mean age was 56 years (SD, 16 years; range, 11 to 82 years). The mean follow-up was 50 months (SD, 44 months; range, 1 to 181 months).

Bipolar radiofrequency-induced thermotherapy (rfitt) for the treatment of spasmodic dysphonia. A report of three cases.

The symptoms of adductor spasmodic dysphonia are most commonly palliated by periodic botulinum toxin injections. The need for repeated injections, difficulty in obtaining injections and cost make this form of treatment intolerable for some patients. To address these concerns, we propose a new treatment approach utilizing trans-oral recurrent nerve coagulation.

Conservation laryngeal surgery for selected pyriform sinus cancer.

Aims: This study reports the treatment of a cohort of patients with pyriform sinus squamous cell carcinoma, using conservative surgery and radiotherapy.

Methods: Thirty-four patients with pyriform sinus SCC were treated between 1986 and 2001, using partial laryngopharyngectomy with or without complementary radiotherapy. Seventy-six percent had stage III-IV lesions.

Parapharyngeal metastases from thyroid cancer.

Aim: To emphasise the pattern of lymphatic dissemination in the parapharyngeal space from thyroid cancer.

Patients And Method: Among 696 patients treated for thyroid cancer between 1986 and 2001, parapharyngeal metastasis was diagnosed in three patients, previously treated for papillary thyroid carcinoma.

Results: All three patients have been treated by surgical resection through lateral cervical approach.

Gastric choristoma of the midline neck in a newborn: a case report and review of the literature.

The current report describes a 3-week-old boy presenting with a gastric choristoma of the anterior compartment of the neck. Initial examination at birth found 3 masses in the anterior region of the neck. The only remarkable symptom consisted of episodes of cyanosis induced by neck flexion.

Perilymphatic pressure measurement in Meniere's disease.

The aim of this study was to evaluate the perilymphatic pressure, by means of the MMS-10 Tympanic Displacement Analyzer (TDA), in patients with Meniere's disease (MD). Measurements were performed in 37 patients with MD and in 14 normal-hearing subjects. Data were collected from 3 groups: healthy ears of normal-hearing subjects, unaffected ears of patients with MD, and affected ears of patients with MD.

Lymphatic malformations of the head and neck: a retrospective review and a support for staging.

Background: Lymphatic malformations (LM) are rare benign congenital tumors appearing mainly in the head and neck with a considerably variable outcome. A need exists to validate a staging system, taking into account the prognosis of the malformation, including preoperative and postoperative complications, long-term sequelae, and persistence of the disease to improve parental counseling and evaluate the outcome of a surgical treatment of such tumors.

Methods: Twenty-two patients treated for LM were selected from a series of 129 patients operated on for congenital malformations of the head and neck between 1986 and 1997 at St-Luc University Hospital, Brussels, Belgium.

Obstructive sleep apnea syndrome after reconstructive laryngectomy for glottic carcinoma.

Obstructive sleep apnea syndrome (OSAS) is characterized by repetitive episodes of partial or complete obstruction of the upper airway during sleep. The obstruction predominantly occurs along the pharyngeal airway but other sites of obstruction have occasionally been described. We report our experience with three patients suffering from OSAS suspected to be of laryngeal origin.
