Reconstruction of oblique facial cleft deformity with adjacent flap and nasolabial flap: A case report.

Introduction And Importance: Oblique facial clefts are uncommon congenital facial deformities. Among them, Tessier No. 3 cleft is an even rare malformation. This study presents a reconstructive option and curative effect for oblique facial cleft deformity of Tessier No. 3.

Case Presentation: A 10-year-old girl was admitted to our hospital with "congenital facial deformity of right nose and mid-face". The clinical diagnosis was "oblique facial cleft of Tessier classification No. 3", also known as "naso-orbital cleft". The cleft was surgically repaired with an adjacent flap and nasolabial flap. After surgery, the case underwent uneventful healing with a surviving flap, and the deformity was well repaired. At 3 months to 1 year of follow-up, the flap had a similar feature (color and texture) to the contralateral tissue. A good outcome was obtained with minimal scar and face deformity.

Clinical Discussion: Facial cleft is a clinical type of craniofacial cleft. The soft tissue feature of Tessier No. 3 cleft is that the fissure is located in the joint part of the middle nose, lateral nose, and maxillary process. The operation adopts the method of closing the fissure with soft tissue flap and pedicled flap transplantation is a priority method. In this clinical case, the patient with oblique facial cleft of Tessier classification No. 3 was repaired by the adjacent flap and nasolabial flap.

Conclusion: The application of the adjacent flap and nasolabial flap is a viable option for the reconstruction of oblique facial cleft deformity of Tessier No. 3 in oral surgery.
