Median alveolar cleft and palatal mass without a median upper cleft lip

Abstract

Median cleft is rare among facial clefts, including bilateral and unilateral clefts. Median upper cleft lip and median alveolar cleft correspond to Type 14 and Type 0, respectively, in Tessier's classification system. Some authors have reported surgical procedures for median cleft. In the case of median alveolar cleft, bone grafting to the cleft side and orthodontics are generally applied, similarly to bilateral or unilateral cleft. Median alveolar cleft is usually accompanied by median upper cleft lip, the degree of which differs in each case. The symptoms include, but are not limited to, median lip defect, wide philtrum, and vermilion notch. However, an isolated alveolar cleft is extremely rare. We encountered a patient with an isolated alveolar cleft who did not have a light median upper cleft lip, such as a wide philtrum or vermilion notch. We herein report this case and describe its treatment.
