Abstract:
BACKGROUND AND OBJECTIVES: Supraglottic laryngectomy is a well established technique for the treatment of appropriate carcinoma of supraglottic larynx. The purpose of this study was to determine factors that may contribute to postoperative aspiration related to deglutition problem following supraglottic laryngectomy. MATERIALS AND METHOD: A retrospective analysis of medical records of 19 patients who consecutively underwent supraglottic laryngectomy was undertaken. Contribution of the following factors was investigated: age, T stage, pack-years of smoking, and parameters of pulmonary function test. The authors used a computerized acoustic analysis program (CSL-MDVP) to measure fundamental frequency, jitter, shimmer, and noise to harmonics ratio. RESULTS: Eleven patients had no problem, 5 patients had clinically insignificant problem, and 3 patients had moderate problem in postoperative 6 months. A greater number of pack-years of smoking and decreasing FEV1/FVC were significantly correlated with poor outcome with regards to postoperative aspiration and deglutition problem. No statistically significant difference was seen between patients with supraglottic laryngectomy and the control group. CONCLUSION: This study showed that less than 60% FEV1/FVC signifies a greater risk for postoperative aspiration.
