Development of a new method and device for adaptation and suture of tissues during transoral surgery: in vitro and cadaver experiments.
OBJECTIVE
The objective of this study was to present cadaver and model experiments of a technique using an instrument that may overcome the problems of achieving adaptation and suture of mucous membrane and other tissues during transoral surgery in narrow anatomical circumstances.


METHODS
The following interventions were carried out on cadavers: adaptation and suture of mucous membrane by uvulopalatopharyngoplasty (UPPP); release and anteroposition of the epiglottis and fixation to the vallecula or to the base of the tongue; denudation and closing the lumen of the larynx; release and retroposition and fixation of the epiglottis to the posterior part of the larynx; creation, adaptation, and suturing of mucosal flaps in the posterior part of the larynx; craniolateral mobilization and fixation of the vocal cord; submucous excision of excess tissues; and adaptation and suture of the edges of the mucosa.


RESULTS
The safety and reduced need for microclips in surgeries in these areas can be accomplished by introducing the Ligature-Suture device, which makes it possible to pass a suture under the tissues with a single movement.


CONCLUSIONS
This new technique and instrument for the Ligature-Suture device has the potential to be applied successfully in other fields of surgery. The main advantages of this technique are its simplicity and safety.
