A new technique for closure of large meningomyelocele defects.

Background: Although small meningomyeloceles may be amenable to direct closure by undermining of the surrounding skin, the closure of large meningomyelocele defects is a challenging reconstructive problem.

Purpose: Here, we present a new surgical procedure for the closure of large meningomyelocele defects.

Material And Methods: In this procedure, after neurosurgical repair and closure of the placode, the defect is surgically converted to a triangle in shape. Then, the triangular defect is closed by transposition of 2 skin flaps designed in an unequal z-plasty manner. Over 3 years, this new technique, namely Mutaf triangular closure procedure, was used for the closure of large meningomyelocele defects in 5 patients, aged between 2 days to 6 weeks. The defect size was 10.4 x 7.5 cm on average.

Results: In all patients, a tension-free 1-stage closure was obtained. Except one with a minimal hematoma, all patients healed with no complication. There was no patient with late breakdown of the wound during 2 years of mean follow-up.

Conclusions: Besides the 2 major advantages of short operative time and minimal blood loss, our technique provides a well-vascularized soft tissue padding over the neural tissues, and no suture line overlies the cord closure. With these advantages, this new technique seems to be a useful and safe solution for closure of large meningomyelocele defects.
