Objective:
An inspiring early result with no oronasal fistula formation was recently described for a modified medial incision small double-opposing Z-plasty (MIsDOZ) for treating Veau type I cleft palate. This study describes an early single-surgeon experience in applying this newly proposed surgical approach.
Design:
Retrospective single-surgeon study.
Patients:
Consecutive nonsyndromic patients (n = 27) with Veau I cleft palate.
Interventions:
Topographic anatomical-guided MIsDOZ palatoplasty with pyramidal space dissection (releasing of the ligamentous fibers in the greater palatine neurovascular bundle and pyramidal process region, in-fracture of the pterygoid hamulus, and widening of space of Ernst) performed by a novice surgeon (RD).
Mean Outcome Measures:
Age at surgery, the presence of cleft lip, palatal cleft width, use of lateral relaxing incision, and 6-month complication rate (bleeding, dehiscence, fistula, and flap necrosis). A published senior surgeon-based outcome dataset (n = 24) was retrieved for comparison purposes.
Results:
Twenty-two (81.5%) and 5 (18.5%) patients received the medial incision only technique and lateral incision technique, respectively (P = .002). Age, presence of cleft lip, and cleft width were not associated (all P > .05) with the use of lateral incision. Comparative analysis between the novice surgeon- and senior surgeon-based datasets revealed no significant differences for sex (females: 74.1% vs 62.5%; P = .546), age (10.2 ± 1.7 vs 9.6 ± 1.2 months; P = .143), rate of lateral incision (18.5% vs 4.2%; P = .195), and postoperative complication rate (0% vs 0%).
Conclusion:
This modified DOZ palatoplasty proved to be a reproducible procedure for Veau I cleft palate closure, with reduced need for lateral incision and with no early complication.
