Submucosal dissection to close wide cleft palate with folded mucoperiosteum for bilateral cleft lip and palate with popliteal pterygium syndrome.

Characteristic features of popliteal pterygium syndrome (PPS) associated with the craniofacial region include cleft palate, syngnathia, and difficulty with reconstruction. We developed a new procedure of submucosal dissection with periosteotomy to close the folded mucosa in bilateral cleft lip and palate patients with PPS. This technique could be applicable for patients with wide cleft palate.
