Summary

After the description of Le Fort fractures, maxillary osteotomies are used to correct dentofacial deformities. The profile changes on nasolabial region resulting from a Le Fort I osteotomy, also that affects nasal airway. The Subspinal Le Fort I osteotomy (SLFIO) describe to prevent undesirable soft tissue changes. In the literature, too many articles have reported the effectiveness of SLFIO in preventing nasal deformation. However, there is no study to evaluate the nasal volume or septum deviation.

Detailed description

The purpose of this study was objectively and subjectively to compare the effect of Subspinal Le Fort I Osteotomy and Conventional Le Fort I Osteotomy on nasal airway volume and septum deviation without additional modification such as Ans Reduction, Alar Cinch Suture, V-Y closure. Surgical procedure; Patients were underwent general anesthesia for bimaxillary orthognathic surgery. The mucoperiosteal flap was raised to expose the bilateral infraorbital foramina, aperture pyriformis, zygomaticomaxillary, and pterygomaxillary buttress. No dissection was performed between the nasal mucosa and the ANS of the patients in Subspinal Le Fort osteotomy group.A triangular osteotomy line was created between the maxilla and the ANS with a piezosurgery. In Conventional osteotomy group, Le Fort I osteotomy was made using a piezosurgical saw after nasal mucosa elevation. In both groups, osteotomes and pterygoid plaques, nasal septum, and lateral nasal walls were separated. Follow up: septum deviation and nasal. airway volume value was measured and recorded in the CBCT images taken before the surgery and at the 6th month after the surgery of each patient.
