Abstract
BACKGROUND: The purpose of this study was to assess the utility of the pectoralis major muscle flap (PMMF) in the prevention of pharyngocutaneous fistula for total laryngectomy after radiotherapy (RT) METHODS: We conducted a retrospective review of 166 patients who underwent a total laryngectomy after RT between 1998 and 2012 at the CHU de Québec. RESULTS: One hundred fifteen patients underwent a total laryngectomy with primary pharyngeal closure alone and 51 patients received an onlay PMMF. The incidence of pharyngocutaneous fistula in the PMMF group was 14% compared to 36% when only primary closure was done (p = .004). However, the PMMF did not influence the treatment needed for the healing of this complication (p = 1.00). The development of pharyngocutaneous fistula increased the length of stay from 19 to 50 days (p < .0001) and delayed the initiation of oral diet from 15 to 25 days (p = .03). CONCLUSION: Nonirradiated tissue coverage should be routine in total laryngectomy after RT. PMMF is a good adjunct to prevent pharyngocutaneous fistula.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
