Objective: The objective is to describe a technique for closing myelomeningocele in newborns, using joint flaps with resulting "H" healing.

Material and Method / Case series: Description of the myelomeningocele closure technique in four cases of children born between 2017 and 2019 in a public hospital in the state of Minas Gerais, with outpatient follow-up until 2024. According to the technique, variations in surgical time, advanced outcomes, and risk of complications, such as infections and cerebrospinal fluid fistula, are proven.

Results: Of the four serial cases, all newborns were full-term gestational age and were approached after the first hours of birth, and the average surgical time for correction of the congenital defect was approximately two hours. Of the cases listed, three were lumbosacral myelomeningocele and one was thoracic myelomeningocele. In all cases, the malformation was previously recognized prenatally. After identification and dissection of the placode, a rotation flap was created and the skin was sutured in layers, resulting in an "H" scar. After the surgery, was not related infections or cerebrospinal fluid leaks during the follow-up period.

Conclusion: Based on the clinical cases presented, it is possible to conclude that the use of the rotation flap with an "H" scar was effective in preventing the occurrence of infections or cerebrospinal fluid leaks potentially associated with the procedure. It is also possible to conclude that, with adequate training, the technique can be replicated with reasonable surgical time and intraoperative safety.
