Abstract
BackgroundTransverse facial clefts are Tessier’s number 7 facial cleft among numbers 1–15 in Tessier’s classification of craniofacial malformations, which varies from a simple widening oral commissure to a complete fissure extending towards the external ear.Case presentationIn a patient with a transverse facial cleft, to functionally arrange the orbicularis oris muscle and form the oral commissure naturally, we performed a surgical procedure including orbicularis oris muscle reconstruction and cheiloplasty with Z-plasty.ConclusionWe achieved good results functionally and esthetically by orbicularis oris muscle reconstruction and cheiloplasty with Z-plasty. The surgical modality of our anatomical repair and 3 months follow-up results are presented.
Highlights
Transverse facial clefts are Tessier’s number 7 facial cleft among numbers 1–15 in Tessier’s classification of craniofacial malformations, which varies from a simple widening oral commissure to a complete fissure extending towards the external ear
Transverse facial clefts are more common in men than in women
The prevalence varies according to statistics, but the incidence is approximately 1 in 80,000 live births, and approximately 10–20% of the cases of transverse facial clefts are bilateral, which represents about 5.5% of the cases based on the Tessier classification [6,7,8]
Summary
The transverse facial cleft is a type of congenital facial anomaly that occurs rarely in Korea as mentioned above. Pronunciation, and swallowing, an appropriate surgical approach is essential, and the oral and maxillofacial surgeons should be familiar with the clinical technique. As repositioning of the intraoral mucosa and of the orbicularis oris muscle is crucial, it is necessary to learn various approaches for skin incisions. In this transverse facial cleft case, we have performed a surgical procedure using advanced orbicularis oris muscle reconstruction and cheiloplasty with Z-plasty. We obtained symmetry of both oral commissure and esthetically good results
