Clinical anatomy of superior laryngeal artery via transoral approach.

Objective: Hemorrhage is the most common complication caused by transoral laryngopharyngeal surgery. It is believed that proper management of the superior laryngeal artery (SLA), the main feeding artery for the larynx and pharynx, may reduce intra- and postoperative hemorrhage incidence. The aim of this study was to illustrate the anatomy of the SLA via transoral endoscopic approach.

Clinical Effects of Radiofrequency Coblation for Adult Laryngopharyngeal Vascular Lesions.

Objective: To explore the feasibility and efficacy of transoral radiofrequency coblation surgery (TRS) in the treatment of adult laryngopharyngeal vascular lesion (LVL).

Methods: A total of 15 patients with LVL were retrospectively studied, including 11 capillary lesions and five cavernous lesions (there was one case with two separate lesions). All of the lesions were treated with TRS alone (capillary lesion) or with a combination of TRS and sclerotherapy (cavernous lesion).

Knowledge of laryngopharyngeal reflux disease among otolaryngologists in 3A hospitals in Beijing.

Objective: This study aimed to evaluate knowledge of laryngopharyngeal reflux disease (LPRD) among otolaryngologists in 3A hospitals in Beijing.

Methods: A cross-sectional questionnaire survey of LPRD knowledge was conducted with otolaryngologists in 40 3A hospitals in Beijing. A response rate of <80% was obtained from one hospital, so data from 331 valid questionnaires from the other 39 hospitals were analysed.
