Comparison of upper airway obstruction during zolpidem-induced sleep and propofol-induced sleep in patients with obstructive sleep apnea: a pilot study.

Study Objectives: Drug-induced sleep endoscopy (DISE) using propofol is commonly used to identify the pharyngeal structure involved in collapse among patients with obstructive sleep apnea. DISE has never been compared with zolpidem-induced sleep endoscopy. We hypothesized that propofol at recommended sedation levels does not influence upper airway collapsibility nor the frequency of multilevel pharyngeal collapse as compared with zolpidem-induced sleep.

Transpterygoid approach to a dermoid cyst in pterygopalatine fossa.

Objective To describe a case of dermoid cyst arising from the pterygopalatine fossa and review the literature. Methods We report a case of a 23-year-old man who suffered a car accident 2 years before otolaryngologic attendance. He had one episode of generalized tonic-clonic seizure and developed a reduction of visual acuity of the left side after the accident.

Giant nasolabial cyst treated using neumann incision: case report.

Introduction A nasolabial cyst is an ectodermal development cyst. It presents as a fullness of canine fossa, nasal ala, or vestibule of the nose. It is rare and usually small.

Prevalence of allergic rhinitis and its impact on the use of emergency care services in a group of children and adolescents with moderate to severe persistent asthma.

Objective: To assess the prevalence of allergic rhinitis and the factors associated with the use of emergency care services by children and adolescents with acute asthma submitted to inhaled corticosteroid therapy.

Methods: A cross-sectional study was conducted with 126 patients treated with beclomethasone dipropionate for 3 years. The factors associated with emergency care services in the third year of beclomethasone dipropionate treatment were assessed using logistic regression models.
