THE IMPACT OF SURGICAL DEFECTS ON POSTOPERATIVE SWALLOWING FUNCTION IN ORAL AND OROPHARYNGEAL CANCER PATIENTS: AN EVALUATION USING FIBEROPTIC ENDOSCOPIC EVALUATION OF SWALLOWING
Main Article Content
Abstract
Objectives: This study aimed to describe surgical defect characteristics and dysphagia presentations on FEES in 89 oral and oropharyngeal cancer patients one month after surgery, and to analyze the correlation between these two factors. Methods: A descriptive cross-sectional study was conducted on 89 oral and oropharyngeal cancer patients one month after surgery. Surgical defect characteristics were recorded. Dysphagia was evaluated with FEES. The FEES assessment criteria included penetration-aspiration during swallowing, and post-swallow residue in the oropharynx and hypopharynx. Mann-Whitney U and Kruskal-Wallis H tests were used for statistical comparison between groups. Results: The study included 89 patients (80.9% male, mean age 53.84 ± 12.291). Common defects included suprahyoid muscle resection (52.8%) and tongue resection (39.3% was partial mobile tongue resection). Penetration-aspiration during swallowing occurred mainly with thin liquids (10.1% aspiration rate), while food residue was more prevalent with moderately and extremely thick liquids. The analysis revealed a significant statistical relationship between several surgical defects (suprahyoid muscles, pharyngeal constrictors, tongue base, mobile tongue, soft palate) and FEES-based dysphagia parameters. Conclusion: Surgical defect characteristics are a significant prognostic factor for postoperative dysphagia in patients with oral and oropharyngeal cancer. These findings provide a basis for early counseling and individualized swallowing rehabilitation interventions.
