Functional study of the voice and swallowing following supracricoid laryngectomy.

UNLABELLED To identify the grade and evolution of dysphagia and dysphonia in patients undergoing supracricoid laringectomy, and to study the association of these findings with clinical and surgical variables. METHOD The study included 22 cases undergoing supracricoid laringectomy at the Head and Neck Surgery and Otolaryngology Department of the Heliopolis Hospital - Brasil, and referred to speech therapy. Dysphagia and dysphonia were correlated with gender, age, stage T (T1, T2, T3, T4), primary site (supraglottis, glottis or subglottis), preservation of one or two arytenoids, reconstructive procedures (cricohyoidopexy or cricohyoidoepiglotopexy), time to withdraw the naso-enteral tube, and time to close the tracheostomy. Statistical tests included the Chi-square and/or Fischers exact test. RESULT We observed an association between moderate grade dysphagia and the glottis as the primary site, cricohyoidoepiglotopexy as the type of reconstruction and naso-enteral tube removal within one month after the surgery. There was also an association between severe dysphagia and the supraglottis as the primary site. Dysphagia and dysphonia were associated in the degree of severity; however a larger number of patients had better progression of dysphagia compared to the progression of dysphonia. There was no statistical significance between other associations. CONCLUSION Improvement of swallowing is more frequent than improvement of dysphagia. There is an association between moderate dysphagia and the glotttis as primary site, cricohyoidoepiglotopexy and naso-enteral tube removal within one month after surgery.
