BACKGROUND: Laryngeal cancer accounts for 1% of all cancers in men and 0.3% of all cancers in women. Pharyngolaryngectomy (TPL) and total laryngectomy (TL) are central surgical techniques in the management of advanced laryngeal malignancies but are associated with significant morbidity. In addition, optimal reconstruction following TPL remains an area of active research. METHODS: Here, we compared speech and swallowing outcomes following circumferential and partial pharyngeal resection alongside total laryngectomy in patients with laryngeal and hypolaryngeal tumors. We performed a systemic analysis of patient demographics, tumor characteristics, treatment modality, and pharyngeal reconstruction technique following TPL and TL, leveraging data collected over a 20-year period at a large tertiary referral center. RESULTS: Analyzing 155 patients the results show circumferential pharyngeal defects and prior radiotherapy have a significant impact on surgical complications. CONCLUSION: Pharyngeal resection carries a substantial risk of incurring impaired speech and swallowing in patients. Moreover, our results support poorer functional outcomes with more radical pharyngeal resections and show a clear trend toward worse swallowing outcomes in salvage surgery.
