AI Article Synopsis
- Total laryngectomy is a common treatment for laryngeal and hypopharyngeal cancer that often results in loss of ability to speak, so this study aimed to evaluate two specific surgical methods—modified Amatsu and modified Pearson—for their effectiveness in restoring phonation.
- The study analyzed data from 69 patients who underwent these surgeries from 1996 to 2003, assessing their phonation abilities using objective and subjective measures, and comparing the results to those from patients who had different types of laryngectomy and healthy individuals.
- Findings showed that most patients regained phonation function after surgery, with high survival rates and satisfactory phonation quality, indicating that both modified Amatsu and modified Pearson operations are effective options for voice
Article Abstract
Background & Objective: Total laryngectomy is a common surgery pattern for treating laryngeal and hypopharyngeal cancer, but patients will lost phonation function after operation. This study was to retrospectively analyze usage of modified Amatsu, and modified Pearson operation in treating laryngeal and hypopharyngeal cancers, and to analyze phonation function by subjective and objective assessment.
Methods: Clinical data of 69 patients with laryngeal or hypopharyngeal cancer treated by total or near-total laryngectomy (modified Amatsu or modified Pearson operation) in our department from 1996 to 2003 were retrospectively analyzed. Phonation function of 69 patients was evaluated by acoustic analysis and Jiyan classification method, and compared with phonation quality of patients received vertical hemilaryngectomy (VHL) and healthy people.
Results: No patient appeared obvious aspiration. Four cases with post-operative radiotherapy all regained phonation function. The 3-year survival rate was 88% (22/25); 5-year survival rate was 80% (4/5). Results of acoustic assessment, and Jiyan classification method indicated that phonation function of patients received modified Amatsu or modified Pearson operation could meet daily requirements.
Conclusions: Modified Amatsu and modified Pearson operations can be learnt and applied easily for phonation reconstruction after laryngectomy. They may be optional surgery patterns, especially modified Pearson operation.
