Abstract
The purpose of this report is to describe the anaesthetic considerations for layngoplastic procedures. Thyroplasty is a procedure which restores the voice in unilateral vocal cord paralysis. The procedure employs an external approach via a window cut at the appropriate level in the thyroid ala. A wedge of silastic is inserted against the inner perichondrium, thereby displacing the vocal cord medially and permitting voice production. Correct placement of the implant is assessed by asking the patient to phonate; patient cooperation is therefore necessary at certain times during the procedure. We describe our management of a patient undergoing thyroplasty. The use of a benzodiazepine agonist-antagonist combination provided both optimal operating conditions and patient comfort.
