True Median Cleft With Sinus Tract in the Nasal Septum: A Case Report.

A true median cleft is an extremely rare congenital anomaly characterized by a midline vertical cleft and various deformities, also known as Tessier number 0 cleft. Here we report a case of a 5-year-old Asian boy with true median cleft associated with sinus tracts in the nasal septum, a phenomenon not previously reported in the literature. The tracts were identified as the cause of recurrent infections around the oral vestibule and upper lip. The tracts were resected successfully, and postoperative progress has been satisfactory. We discuss the importance of preoperative image evaluations and the selection of a suitable surgical approach.
