Background And Aim:
This study aims to assess the impact of supraglottic cancer on swallowing functionality and its anatomical correlations before and after laser surgery. The study seeks to determine the extent of score changes post-surgery, pinpoint the most influential anatomical component in swallowing, predict post-surgery outcomes, and ascertain the effect on patients' quality of life.
Methods:
Patients with supraglottic cancer and dysphagia were identified through stroboscopy and indirect laryngoscopy. Exclusion criteria encompassed a history of prior radiotherapy, chemotherapy, or distant metastases. Demographic data, tumor stage, comorbidities, risk factors, and treatment details were documented. Swallowing evaluation employed the translated EAT10 self-assessment questionnaire, administered before and after transoral laser microsurgery (TLM) at baseline and 6 months later. Additional treatments, rehabilitation duration, NG tube use, and post-surgery complications were recorded.
Results:
At the six-month follow-up, 9 patients had EAT-10 scores ≥ 3, while 7 patients scored < 3. Five patients underwent post-TLM additional therapies, and 9 patients had neck dissections. Involved subunits were epiglottis (11 patients), arytenoid (5 patients), FVC (13 patients), and TVC (3 patients). Seven patients received dysphagia treatment. Analysis revealed significant associations between follow-up EAT-10 scores and dysphagia treatment (p = 0.04), smoking (p = 0.02), and FVC involvement (p = 0.02).
Conclusion:
Our study on supraglottic cancer treatment with transoral laser microsurgery (TLM) revealed variable EAT-10 scores after a six-month follow-up. Adjunctive therapies and neck dissections were administered to some patients. Significant associations were found between follow-up scores, dysphagia treatment, smoking history, and FVC involvement, highlighting the complex interplay between interventions and patient factors. Further research is needed for optimization.
