Back closure with a latissimus dorsi myocutaneous flap

Area of Science:

• Plastic Surgery
• Pediatric Neurosurgery
• Congenital Abnormalities

Background:

• Myelomeningocele, a severe birth defect, often results in large thoracolumbar defects requiring complex surgical closure.
• Standard closure methods can be associated with high rates of complications, including flap necrosis and infection.

Purpose of the Study:

• To report a novel surgical technique for back closure in myelomeningocele using a latissimus dorsi myocutaneous flap.
• To evaluate the efficacy and safety of this three-layer flap closure in newborns with large thoracolumbar defects.

Main Methods:

• A latissimus dorsi myocutaneous flap, comprising skin, subcutaneous fat, and innervated muscle, was utilized for defect coverage.
• The flap's robust blood supply and innervation were critical for successful graft survival and wound healing.
• The technique was applied to 30 consecutive cases of newborns diagnosed with large thoracolumbar myelomeningocele.

Main Results:

• The three-layer flap closure technique demonstrated successful closure of large thoracolumbar myelomeningocele defects.
• Well-vascularized coverage provided by the flap significantly reduced the incidence of partial flap necrosis and wound breakdown.
• The method effectively prevented central nervous system infections secondary to wound complications.

Conclusions:

• The latissimus dorsi myocutaneous flap offers a reliable and effective solution for closing large myelomeningocele defects in newborns.
• This surgical approach enhances wound healing and minimizes the risk of severe complications, improving patient outcomes.
