Long-Term Assessment of Speech and Swallowing Function in Laryngopharyngeal Cancer Patients After J-Flap Reconstruction

Objectives. A novel J-shaped anterolateral thigh (ALT) flap reconstruction technique was developed to simultaneously restore swallowing and speech functions in patients following total laryngopharyngectomy. This study aimed to assess the outcomes and surgical complications in patients who underwent J-flap reconstruction over time. Methods. Patients who underwent J-shaped ALT flap phonatory tube reconstruction were enrolled. Surgical morbidities and outcomes were evaluated every 3 months post-surgery for a period of 12 months or until death. Results. Of the 36 patients, 13 underwent circumferential pharyngeal wall resection (circumferential defect [CD] group), and 23 underwent partial resection (partial defect [PD] group).After 12 months, 97% of the patients were able to resume oral intake without the need for a nasogastric tube, and 50% achieved fluent speech using the reconstructed phonatory tube. The CD group experienced a higher rate of delayed healing than the PD group (30.8% vs. 0%, P=0.012). Additionally, the PD group showed significantly higher percentages of individuals consuming solid food at both the 3-and 12-month intervals than the CD group (81.0% vs. 23.1% and 78.9% vs. 40%, respectively). Conclusions. This study investigated the progression of speech and swallowing functions over time after reconstruction of the voice tube with a J-flap. Using a J-shaped ALT flap phonatory tube effectively restored both speech and swallowing functions, providing long-term benefits, regardless of whether the defect was circumferential or partial.
