A new 4-class system helps reconstruct oropharyngeal defects after transoral robotic surgery (TORS). This classification guides reconstruction, with adjuvant radiotherapy predicting poorer swallowing outcomes.

Area of Science:

  • Otolaryngology
  • Head and Neck Surgery
  • Surgical Oncology

Background:

  • Transoral techniques like transoral robotic surgery (TORS) for oropharyngeal tumors necessitate novel reconstructive strategies.
  • Oropharyngeal cancer treatment has evolved, increasing the need for specialized reconstructive methods.

Purpose of the Study:

  • To introduce and validate a classification system for oropharyngeal defects resulting from transoral robotic surgery (TORS).
  • To correlate defect classification with reconstructive techniques and patient outcomes.

Main Methods:

  • A cohort of 92 patients undergoing TORS for oropharyngeal tumors was analyzed.
  • Defects were classified into 4 distinct categories, guiding a standardized reconstruction algorithm.
  • Perioperative outcomes, complications, and patient-reported swallowing (MDADI) and velopharyngeal function (VPIQL) were assessed.

Main Results:

  • The most frequent reconstructions included velopharyngoplasties with local flaps (39%), local flaps alone (25%), and secondary healing (20%).
  • Advanced defects (Class III and IV) more commonly necessitated regional and free flaps.
  • No significant differences in MDADI or VPIQL scores were observed across the four defect classes; however, adjuvant radiotherapy emerged as a predictor of poorer swallowing outcomes (p = .02).

Conclusions:

  • The proposed 4-class system effectively categorizes transoral oropharyngeal defects.
  • This classification aids in directing the reconstructive approach for TORS defects.
  • Adjuvant radiotherapy is a significant factor influencing postoperative swallowing function.
