To investigate rates of obesity and obstructive sleep apnea (OSA) in patients with a diagnosis of superior semicircular canal dehiscence (SSCD).

OBJECTIVE To investigate the association between semicircular canal dehiscence (SCD) and Chiari type I malformation (CM-I). DESIGN Retrospective case series. SETTING Military tertiary referral center. PATIENTS Adult patients with SCD. INTERVENTION Review of records of patients diagnosed as having SCD for the radiologic diagnosis of CM-I and presenting symptoms. MAIN OUTCOME MEASURES The prevalence of CM-I among patients with SCD and the presenting symptoms of patients with SCD with and without a coexistent CM-I. RESULTS Of 32 patients diagnosed as having SCD, 30 underwent magnetic resonance imaging of the brain. Seven patients (23%; 95% confidence interval [CI], 12%-41%) were found to have a CM-I. Chiari type I malformation was associated with superior SCD in 3 of 26 patients (12%; 95% CI, 3%-30%). Of 10 patients with bilateral superior SCD, 2 (20%; 95% CI, 5%-52%) had a CM-I. Five of 6 patients (83%; 95% CI, 42%-99%) had a CM-I with unilateral or bilateral posterior SCD. Twenty-nine records were reviewed for presenting symptoms, and no significant difference was observed between patients with SCD alone and those with an associated CM-I (P = .09-.64). CONCLUSIONS Among patients with SCD, the prevalence of CM-I is elevated. This association is especially marked in patients with posterior SCD. This finding suggests a relationship between CM-I and SCD, particularly with posterior SCD.Arch Otolaryngol Head Neck Surg. 2010;136(10):1009-1014--

• Involvement of the larynx by mycosis fungoides is extremely rare with only three reported clinical cases in the English-language literature. We present two patients with laryngeal mycosis fungoides, one of whom presented with vocal cord paresis (progressing to paralysis) as the initial clinical manifestation of laryngeal involvement. Our clinical findings and the observations from the three previous case reports suggest that laryngeal mycosis fungoides has a predilection for the arytenoids, aryepiglottic folds, and the laryngeal surface of the epiglottis. Laryngeal involvement, like other forms of visceral dissemination, appears to manifest clinically in the terminal stages of the disease. The natural history, clinical features, histopathology, and treatment of mycosis fungoides are reviewed and the etiopathology of the vocal cord paralysis is described.(Arch Otolaryngol Head Neck Surg. 1992;118:853-858)
