Myelomeningocele defect closure

Myelomeningocele closure by unilateral lumbar artery perforator flap: Experience with thirty-eight patients

BACKGROUND

Repair of large soft tissue defects in meningomyelocele is difficult and its morbidity is high. By applying unilateral lumbar artery perforator transposition flap for closing these defects, we aimed to investigate effects on the repair procedure, duration of surgery and recovery period, with the rates of bleeding and morbidity.

PATIENTS AND METHODS

Our report was conducted in 38 patients between the years 2013 and 2017. All soft tissue defects were repaired with unilateral lumbar artery perforator flap (LAPF) in meningomyelocele. Fourteen patients were female and 24 patients were male. The youngest patient was a 5.5 month premature female baby and weighing 570 g. The oldest was weighing 3,700 g and at 1.5 months old.

RESULTS

Mean flap size was 32 ± 29.4 cm² (ranged: 4 × 3-8 × 7 cm² ). The mean rotation angle was 126.7° (ranged: 90°-170°). Flap positions were separated as 9 (23%) thoracodorsal and 29 (77%) lumbosacral. None of the patients had flap necrosis, infection, or hematoma. The operation took 23 ± 5.3 minutes on average and bleeding was minimal as 16 cc. All patients were discharged within around 9 ± 2 days. The follow-up period of the patient ranged from 4 to 21 months. Flap survival was at the rate of 100%. There was no flap or postoperative complications. Final outcome for all patients were assessed as complete healing. All patients recovered fast with minimal blood lose, and satisfied the outcomes.

CONCLUSIONS

As a result, unilateral lumbar perforator flap can be performed successfully in every center. This report suggests using LAPF for reconstruction of meningomyelocele by surgeons as a safe and reliable option, allowing surgeons strong results.

Facilitating triple rhomboid flaps for meningomyelocele defect closure using a honeycomb structure as a template

PURPOSE

Various reconstruction options are available for the soft-tissue coverage of meningomyelocele defects. For small defects, primary closure or local single flaps may be sufficient, while large defects require more complex reconstructive techniques. This study suggests an easy way for surgeons to close large meningomyelocele defects using triple rhomboid flaps.

METHODS

The hexagonal structure of a honeycomb was considered when planning for the coverage of large meningomyelocele defects. The intact skin around the defect was imagined as multiple hexagons, which allowed us to plan triple rhomboid flaps correctly and more easily. This technique was used in seven patients with defects ranging from 7 × 5 to 12 × 8 cm in size.

RESULTS

No major postoperative complications were seen. Minimal dehiscence was observed in two patients and healed secondarily.

CONCLUSIONS

The honeycomb modification for planning triple rhomboid flaps is an easy, practical, and memorable approach for surgeons reconstructing large meningomyelocele defects.
