Pharyngeal constrictor muscles closure after total laryngectomy is that really benefi cial?
Journal Title: Otolaryngologia Polska - Year 2010, Vol 64, Issue 1
Abstract
High pressure of pharyngo-esophageal segment is the most important factor of impaired development of alaryngeal speech (esophageal speech, tracheoesophageal speech) after total laryngectomy. To prevent pharyngo-esophageal spasm in Department of Otolaryngology in Szczecin are used: pharyngoesophageal plastic surgery with interposition of vascular thyroid fl ap, two-layer (only mucosa) non-muscular pharyngeal closure and tree-layer closure (mucosa and muscle layer leaving inferior pharyngeal constrictor unsutured). Aim of study: The aim of this study was to compare the pharyngo-esophageal pressure between patients after pharyngo-esophageal plastic surgery and following the non-muscular pharyngeal closure. Material and methods: One hundred eighty two subjects after total laryngectomy were enrolled in this study, and included 108 patients subjected to the pharyngo-esophageal plastic surgery, 44 patients who underwent the two-layer pharyngeal closure, and 30 patients with the tree-layer closure. To evaluate the pharyngo-esophageal pressures manometric tests were performed, and to asses the pharynx morphology videopharyngoscopy was used. Results: The average pharyngo-esophageal pressure in the group after the pharyngo-esophageal plastic surgery was 32 (min.-5, max. 50) mmHg. After the two-layer non-muscular pharyngeal closure mean pressure was 35 (min.-17, max.-40) mmHg, and after the tree-layer non-muscular pharyngeal closure the average pressure was 22,42 (min. 5, max. 40) mmHg. The average pharyngo-esophageal pressure was signifi cantly lower (p<0,01) among patients after the tree-layer non-muscular closure. Conclusion: The study suggests that the tree-layer non-muscular pharyngeal closure with inferior pharyngeal constrictor unsutured is the preferable method to prevent pharyngo-esophageal spasm after total laryngectomy. However, the effi cacy and safety of this surgical procedure should be explored in further multicenter studies.
