ABSTRACT
ABSTRACT: The occurrence of a thyroid gland superficially placed on the pharyngeal portion of the tongue is rare but poses problems to the patient and the anesthetist. This report describes a patient with a lingual thyroid whose only positive sign is a vague tone. The stealthiness during preoperative assessment resulted in an unexpected dicult airway condition in a gynecological case. Comprehensive and programmed anesthetic managements including GlideScope, fiber-optic bronchoscope, LMA, and tracheotomy are utilized in the patient. Indications drawn out from the case are as follows: 1. Ectopic thyroid surrounding airway should be paid great attention in future medical activities, oering particular guidance to clinical treatment. 2. Any trifles and clues associated with airway assessment should be brought to the forefront. 3. Both sucient oxygen supply and low side injury are the main points in handling the unexpected dicult airway. It is wise to make preliminary preparation and rational choice among the various kinds of auxiliary intubation or ventilation tools based on the actual situation.
