Laser resection of T1a glottic carcinomas: results and postoperative voice quality.
OBJECTIVE
To calculate recurrence, mortality and complication rates and evaluate postoperative voice quality after laser resection of T(1a) glottic carcinoma.


METHODS
Since 1995 we have treated 118 patients with a T(1a) glottic carcinoma with laser surgery. In order to evaluate postoperative voice quality, patients who were alive and free of recurrence were sent the Voice Handicap Index (VHI) questionnaire containing 30 questions concerning how their voice affects their daily life physically, emotionally and socially.


RESULTS
Twelve patients (10%) had a local recurrence and received further treatment, either a second laser treatment, radiotherapy or a total laryngectomy. One patient (0.84%) died due to the laryngeal cancer. Ninety-nine patients were sent the VHI questionnaire and 94 of the completed questionnaires were included in the study and analyzed. The mean total score was 13.2, with mean subscores of 6.5 (physical), 4.1 (functional) and 2.5 (emotional).


CONCLUSIONS
The results indicate that these patients as a group do not consider that their voice has a negative impact on their daily life. Good surgical technique is essential to obtain a good functional result. The laser strength should be kept low and the surgical margins small in order to minimize scarring and vocal cord stiffness.
