Aims. The aim of the study was to compare endotracheal intubation with i-gel and LMA (laryngeal mask airway) supreme supraglottic airway devices in orbital osteosynthesis surgery. Methods. 134 patients undergoing orbital plasty after fracture were enrolled in our study and were randomized into three groups: 43 in the endotracheal intubation group, 42 in the LMA-Supreme group, and 49 patients w...

RATIONALE Obesity imposes mechanical loads on the upper airway, resulting in flow limitation and obstructive sleep apnea (OSA). In previous animal models, leptin has been considered to serve as a stimulant of ventilation and may prevent respiratory depression during sleep. We hypothesized that variations in leptin concentration among similarly obese individuals will predict differences in compe...

This study aimed to analyze pharyngeal airflow characteristics and their relationship with the skeletal movement of maxilla mandible after bimaxillary orthognathic surgery in patients class III (mandibular prognathism) malocclusion. Cone-beam computed tomography (CBCT) was conducted before (T0), immediately (T1), at least six months (T2). Digital imaging communications medicine files were trans...

HYPOTHESIS An inexpensive and widely applicable technique to monitor recurrent laryngeal nerve (RLN) function during thyroid surgery can be safely implemented. DESIGN Consecutive sample. SETTING Single-surgeon academic practice. PATIENTS Three hundred sixty-three consecutive patients undergoing surgery for thyroid disease in the 18 months from November 1, 1999, to May 31, 2001. INTERVEN...

Computational fluid dynamics (CFD) techniques were used to model the turbulent flow in upper airway model of two subjects with obstructive sleep apnea (OSA). The upper airway models were reconstructed by Mimics software based on computerized tomography (CT) scanned images obtained during quiet tidal breathing. The Large Eddy Simulation (LES), a more accurate approach in unsteady flow, was selec...

Biopsy, using mediastinoscopy is commonly employed for accurate histologic diagnosis of a mediastinal mass. However, since the mass is not removed during the procedure, it may cause compression of vital structures such as major airways, the heart, the pulmonary artery, and the superior vena cava after surgery. We observed a case of a 66-year-old man with a mediastinal mass that caused severe ai...
