Surgery Navigation in Treating Congenital Midfacial Dysplasia of Patients With Facial Cleft.

Aim: To explore a new accurate way for the treatment of congenital midfacial dysplasia in facial cleft patients. Materials and Methods: Between November 2015 and November 2016, 8 patients with nasal deformity and midfacial dysplasia (Tessier Nos. 3-11 cleft) were collected (median age, years; range = 15-20 years). Expanded frontal flap for nasal reconstruction and image-guided navigation-assisted surgery for modified nasal-maxillary-hard palatine osteotomy to advance the peri-pyriform bone structure were performed in all the patients. After 6 to 12 months of follow-up, the authors analyzed the differences between preoperative planning and postoperative results through computed tomography data. Results: Patients were satisfied with surgery, and computed tomography data showed that there was little difference between preoperative planning and postoperative results with the navigation-assisted surgery. Conclusion: Using expanded frontal flap with navigation-assisted surgery for peri-pyriform advancement, the authors could treat congenital nasal deformity and midfacial dysplasia effectively, accurately, and safely in craniofacial cleft patients.
