Introduction And Objectives:
The study goal was to analyze the oncologic and functional outcomes of transoral laser microsurgery in the treatment of carcinoma of the supraglottic larynx.
Material And Methods:
A total of 53 patients were included in this retrospective review between 2000 and 2006. The follow-up period was more than 2 years and the mean follow-up for all patients was 49 months.
Results:
Tumour extension was as follows: T1 in 12 (22.6%), T2 in 37 (69.8%) and T3 in 4 (7.5%). Forty-seven patients (88.7%) had neck dissections. Nineteen patients (35.8%) received adjuvant radiotherapy. Kaplan-Meier estimates for disease-specific survival were 80%, 74.11% and 65%, at 2, 3 and 5 years, respectively. The overall functional laryngeal preservation rate was 90.56%. (48 of 53), and local control 81.13%. During follow up, 13.2% of patients developed local recurrence, 11.3% regional recurrence and 5.7% loco-regional recurrence. Patients started swallowing early after surgery, with a mean time of 5.83 days, and the mean hospital stay was 14.69 days. Complications included 20.75% who suffered pneumonia and 11.32% with bleeding. Only one patient (1.88%) received total laryngectomy due to the impossibility of swallowing.
Conclusions:
With careful selection of patients, laser supraglottic laryngectomy is a safe and effective treatment for cancer of the supraglottic larynx.
