ObjectiveTo determine the early risk factors for enlargement of the tracheoesophageal puncture (TEP) after total laryngectomy.DesignRetrospective cohort study.SettingThe University of Texas MD Anderson Cancer Center, Houston.PatientsThe study included 194 patients who underwent total laryngectomy (with or without pharyngectomy) and TEP (2003-2008).Main Outcome MeasuresMultiple logistic regression methods were used to evaluate early risk factors for an enlarged TEP.ResultsThe incidence of an enlarged TEP was 18.6% (36 of 194 patients). After adjustment for follow-up time and radiotherapy history, patients with nodal metastases had a significantly higher risk of TEP enlargement (adjusted odds ratio, 6.6; 95% CI, 1.6-26.6) than those with node-negative disease. Total laryngopharyngectomy significantly increased the risk of an enlarged TEP (adjusted odds ratio, 4.5; 95% CI, 1.4-14.7) compared with simple total laryngectomy. Before multivariable adjustment, the preoperative body mass index was also significantly associated with enlargement (P for trend, .04).ConclusionsThese data suggest that 2 clinical factors-nodal staging and extent of resection-may help identify those at highest risk for TEP enlargement early after surgery. These simple indicators may ultimately aid in patient selection and prevention of an enlarged TEP after total laryngectomy.
