A ventral rotational skin flap to improve cosmesis and avoid chordee recurrence in epispadias repair
Bibliographic record
Abstract
OBJECTIVE: To describe a technical modification that facilitates dorsal skin closure, improves cosmesis and eliminates chordee recurrence secondary to contracture of the dorsal penile skin in the repair of epispadias. PATIENTS AND METHODS: Eleven patients with penopubic epispadias (mean age 1.8 years) had the epispadias repaired using a modified ventral penile skin flap. Four patients had isolated epispadias and seven had had a previous primary closure of bladder exstrophy. Nine patients underwent the Cantwell-Ransley technique, leaving the meatus in a glanular position. Two patients were repaired using the penile disassembly technique of Mitchell and Bägli, because they had a short urethral plate. A ventral island skin flap was fashioned, starting at the base of the penis. Dissection was carried ventrally into the scrotum to allow for adequate dorsal flap transposition. The flap was rotated laterally to shift the suture line from the midline and to cover the dorsal aspect of the penis with untouched penile shaft skin. Redundant ventral foreskin was discarded. RESULTS: All patients had an uneventful course after surgery. Dorsal penile skin was viable in every case and no patient developed recurrence of chordee or a urethrocutaneous fistula. The cosmetic result was excellent in all patients. CONCLUSIONS: Dorsal skin closure using lateral rotation of ventral penile skin flap improves cosmesis after epispadias repair and eliminates the recurrence of chordee secondary to midline dorsal scarring.

How this classification was reachedexpand
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.
