Residue localization and risk for aspiration in partial laryngectomy: the relevance of assertive therapeutic strategies and resources

Abstract

ABSTRACT Objective: To describe the correlation between the residues, their anatomical location and the presence of laryngotracheal penetration and aspiration in patients after supracricoid laryngectomy undergoing cricohyoidoepiglotopexy reconstruction. Methods: This study included 70 patients treated by supracricoid laryngectomy with cricohyoidoepiglotopexy reconstruction in a referral national cancer hospital. The patients were submitted to swallowing videofluoroscopy, and the findings were classified by the penetration and aspiration scale. The images were described observing the presence or absence of residues and their anatomical location. Results: The prevalence of penetration in this study was 68.6% and aspiration was 34.3%. An association was found between the presence of residue on the tongue (p=0.005), posterior pharyngeal wall (p=0.013), pyriform recesses (p=0.002), valecula (p=0.061), and laryngeal penetration. The residue in the upper esophageal sphincter (p=0.039) was associated with the occurrence of laryngotracheal aspiration. Conclusion: Patients undergoing supracricoid laryngectomy with cricohioidoepiglotopexy reconstruction have food residues in different anatomical regions after swallowing. Penetration was associated with the presence of residues on the base of the tongue and posterior pharyngeal wall. Aspiration was associated with the presence of residues in the upper esophageal sphincter.
