Submandibular Gland Flap Reconstruction for Oropharyngeal Defects After Transoral Robotic Surgery (<scp>TORS</scp>)

摘要

BACKGROUND: To describe utilization and outcomes of submandibular gland flap (SGF) reconstruction after transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC). METHODS: A multi-institutional retrospective case series of patients who underwent TORS for OPSCC followed by SGF reconstruction with harvest via transcervical approach from 1/1/2016 to 4/1/2023. RESULTS: In total, 14 patients underwent SGF reconstruction after TORS for OPSCC. All patients had HPV-positive disease, predominantly in early local (N = 10 with pT1/pT2 disease, 71%) and regional stages (N = 11 with pN0/pN1 disease, 79%). Most patients received adjuvant radiation treatment (N = 9, 64%). Median hospital LOS after surgery was 4 days (IQR 2 days) with median functional oral intake scale (FOIS) score of 5 (IQR 0.8) at 1-3 weeks after surgery. CONCLUSIONS: SGF reconstruction is a useful technique for closure of appropriately selected TORS defects requiring reconstruction beyond healing by secondary intention and mobilization of adjacent tissue but not large enough to warrant free flap reconstruction.
