The aim of the study was a morphometrical macroscopic evaluation of extralaryngeal diameters in elderly people, according to its usefulness in ORL diagnostic and operational methods. Laryngeal preparations together with surrounding structures were taken from cadavers of both sexes, aged 65 and over, about 24 hours after death. Clinically important extralaryngeal diameters were collected using common morphometrical methods. A few body features were also gathered. Computer statistical methods were used in data assessment including basic statistics and linear correlations between diameters, and between diameters and body features. The data presented in the study may be very helpful in diagnostic methods' evaluation. They may also help in: selection of the appropriate operational tool size, choice of the most appropriate operational technique, preoperative preparations and designing and building virtual models for physicians' training.

Introduction: Recurrent laryngeal nerve injury is a major complication of thyroid surgery. An endotracheal tube with electromyography electrodes attached to it was recently developed for intraoperative neuromonitoring during thyroid surgery. Here we describe the successful identification and preservation of an extralaryngeal bifurcation of the recurrent laryngeal nerve by intraoperative neuromonitoring in a patient undergoing thyroid surgery.

Functional laryngeal reinnervation depends upon the precise reinnervation of the laryngeal abductor and adductor muscle groups. While simple end-to-end anastomosis of the recurrent laryngeal nerve (RLN) main trunk results in synkinesis, functional reinnervation can be achieved by selective anastomosis of the abductor and adductor RLN divisions. Few previous studies have examined the intralaryngeal anatomy of the RLN to ascertain the characteristics that may lend themselves to laryngeal reinnervation.

It has been reported that there were no significant changes in the recurrent laryngeal nerves of patients with adductor spasmodic dysphonia, which could explain the cause of this disease. However, the researchers who made these reports appeared to have investigated only the extralaryngeal part of the nerve involved in the neck. Because the recurrent laryngeal nerve contains many components that distribute to various organs, we must study in greater detail a more peripheral part of the motor nerve, which has a much closer relationship to vocal cord movements.

Objective: To determine if perineural invasion (PNI) of small nerves affects the outcome of patients with squamous cell carcinoma (SCC) of the upper aerodigestive tract.
Design: Retrospective clinicopathological study of patients with at least 2 years of follow-up and with negative margins and no prior, synchronous, or metachronous SCC.
Setting: Academic otolaryngology department.
