Horizontal glottectomy.
Horizontal glottectomy is a procedure which allows removal of the whole glottis, together with its cartilaginous framework. It is performed by means of two horizontal incisions, the lower through the cricothyroid membrane, and the upper one across the wings of the thyroid. The gap is then closed by approximating the cricoid to the thyroid remnants (cricothyropexy). The indications for horizontal glottectomy are: 1) "double" cancers (i.e. two independent tumors, one on each vocal cord). 2) Hyperkeratosis of the glottis associated with carcinoma in situ. 3) Verrucous cancers of the glottis. 4) Cancers of one vocal cord invading the opposite one via the anterior commissure. In a period of 4 years, 16 patients have been operated on with good early results.
