Oncologic and functional results of supracricoid partial laryngectomy with cricohyoidopexy.

Objective: Supracricoid partial laryngectomy with cricohyoidopexy (SPL-CHP) is an alternative technique described for extensive tumors of the larynx that are beyond the limits of classical conservation partial laryngectomy and otherwise would be treated by total laryngectomy.

Study Design And Setting: Forty-six patients with carcinoma of the larynx underwent SPL-CHP between 1991 and 2003. The median age was 54 (range, 37 to 72). In 28 cases both arytenoids were spared; in 17 cases, 1 arytenoid was spared; and in 1 case, 2 arytenoids were resected. Bilateral elective neck dissections were performed in supraglottic carcinomas. In glottic carcinomas, neck dissection was performed in the presence of clinically positive lymph nodes. None of the patients were treated with postoperative radiation therapy.

Results: Forty-five patients were successfully decannulated; 1 patient with 2 arytenoids resected could not tolerate decannulation. The mean time for decannulation was 20 days (range, 9 to 60 days) when both arytenoids were spared with SPL-CHP, and 41 days (range, 13 to 150 days) for SPL-CHP when 1 arytenoid was spared. The average time for removal of the feeding tube was 21 days (range, 9 to 60 days) when both arytenoids were spared, and 40 days (range, 16 to 127 days) when 1 arytenoid was spared. The removal time of the feeding tube of the patient with 2 arytenoids resected was postoperative day 63. In 2 patients, aspiration pneumonia occurred as a result of swallowing impairment. In none of the patients temporary or permanent gastrostomy was needed. Two patients had local recurrence and were treated with a total laryngectomy; they are still alive. In 2 patients, secondary primary tumors were detected. The 3-year overall and cause-specific actuarial survival rates were 95.7 % and 87.5 % , respectively.

Conclusions: Although prolonged hospitalization and delaying physiological functions can be termed as disadvantages of SPL-CHP, the operation is a reliable and oncologically valid procedure in selected cases of cancer of the larynx who would otherwise be operated by total laryngectomy.
