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.
