A decision-making guide for the closure of myelomeningocele skin defects with or without primary repair.

Abstract

OBJECTIVE The closure of the skin defect in myelomeningocele (MMC) repair is an essential step that determines the quality of the surgical result. The success of surgical results is related to the decision to use the most suitable techniques, namely flaps or primary closure. The aim of this study was to evaluate the effectiveness of a decision-making guide to determine whether to use primary repair or a flap for the closure of skin defects that occur in MMC. METHODS Fifty patients underwent surgery after neurosurgical repair and closure of the placode. A simple guide was generated according to the defect height/width and posterior axillary lines/defect width ratio. These 2 ratios were considered to determine which closure technique (with or without primary repair) should be used for the MMC defect reconstruction. RESULTS By using this decision-making guide, 20 of the defects were repaired with various flaps, and those of the remaining 30 patients were repaired with primary closure. In all patients, a successful tension-free 1-stage closure was obtained. Except for 4 patients who had flap reconstruction with partial flap necrosis or minimal flap tip necrosis, healing was uneventful without any complications. There were no additional wound complications during the mean follow-up of 6.8 years (range 5 months to 14 years). CONCLUSIONS Because of various defect sizes and patient characteristics, no single protocol exists for the reconstruction of MMC defects. The guide suggested here might be effective in deciding which method is suitable for closure of MMC skin defects.
