Abstract
BACKGROUND: Tracheostomal recurrence after total laryngectomy for laryngeal carcinoma has a poor prognosis. The independent risk factors of tracheostomal recurrence are, however, not well documented. METHODS: This is a multivariate analysis of the risk factors of tracheostomal recurrence after total laryngectomy for 322 laryngeal squamous cell carcinomas. The factors included in the analysis were sex, age, tumor stage, sites of tumor involvement, preoperative airway obstruction, preoperative tracheostomy, extent of surgical resection, radiotherapy, and pathological resection margin. RESULTS: Seventeen (5%) patients developed tracheostomal recurrence. Univariate analysis showed that preoperative airway obstruction, subglottic involvement, and postcricoid extension were significant factors associated with tracheostomal recurrence. Multivariate analysis using logistic regression method showed that both subglottic and postcricoid involvement were independent predisposing factors for tracheostomal recurrence. The tracheostomal recurrence rates were 2% in patients without the risk factor and 10% in patients with the presence of one or both risk factors. CONCLUSIONS: Subglottic and postcricoid involvement were independent risk factors for tracheostomal recurrence.
