Objectives:
In certain instances medialization thyroplasty under local anesthesia is awkward for the patient and complicates surgery. Moreover, for certain operations such as for sulcus vergeture or presbyphonia, subjective auditory appreciation of vocal improvement under operating room conditions is not efficient. In those various instances, we therefore perform thyroplasty under general anaesthesia using a laryngeal mask, and under fibrerscopic control.
Material And Method:
A joint connecting the laryngeal mask to the ventilation tube is angled and comprises a small valve through which a fiberscope is slipped. We have used this method since April 99 for 11 surgery procedures.
Results And Conclusion:
To date, we have not encountered intraoperative complications that have required intubating the patient in order to continue surgery. It can, however, occur that a change in head posture during surgery displaces the mask. In that event, surgery must be momentarily interrupted in order to re-position the mask. The vocal results met expectations.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
