Higher Complication Rates in Self‐Inflicted Gunshot Wounds After Microvascular Free Tissue Transfer
Bibliographic record
Abstract
Objectives/Hypothesis Microvascular free tissue transfer is often employed to reconstruct significant facial defects from ballistic injuries. Herein, we present our comparison of complications between self‐inflicted and non–self‐inflicted gunshot wounds after microvascular free tissue transfer. Study Design Retrospective case review. Methods Approval was obtained from the JPS institutional review board. We performed a retrospective review of cases of ballistic facial injuries between October 1997 and September 2017 that underwent vascularized free tissue transfer for reconstruction. Comparisons were made between self‐inflicted and non–self‐inflicted gunshot wounds after microvascular free tissue transfer. The χ 2 test was used for all comparisons. P value and 95% confidence interval (CI) were reported. Results There were 73 patients requiring free flap reconstruction after gunshot wounds to the face during the study period. There was a statistically significant difference in the rates of nonunion between self‐inflicted and non–self‐inflicted wounds ( P = .02, 95% CI: 0.9 to 35.8) There were also no significant differences in flap failure ( P = .10, 95% CI: −2.8 to 24.2), plate exposure ( P = .28, 95% CI: −6.7 to 33.0), wound infection ( P = .40, 95% CI: −8.9 to 31.2), scar contracture ( P = .60, 95% CI: −8.1 to 25.1), and fistula formation ( P = .13, 95% CI: −2.8 to 28.8) between patients with self‐inflicted and those with non–self‐inflicted wounds. Overall, complication rates were significantly higher in the self‐inflicted group compared to the non–self‐inflicted group ( P < .0001, 95% CI: 32.6 to 68.6). Conclusions Patients with self‐inflicted injuries had more complications postoperatively than those with non–self‐inflicted injuries. This is likely helpful in surgical planning and patient counseling. Level of Evidence 4 Laryngoscope , 129:837–840, 2019

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
