“…However, the amount of bone removal in the former is 1-2 mm at most, and in the latter, although it is worth discussing, there is a decrease in oral volume, which is not necessarily good because it may affect the OSAS. There are also reports of fractures of the inferior turbinate to avoid interference, and no patient complained of symptoms such as nasal congestion after surgery, 16 which may be one of the effective means. If the superior movement of the maxillary bone is large, it may be most effective to remove the inferior turbinate.…”

Objective: There are cases in which patients complain of nasal obstruction after Le Fort I osteotomy, but the relationship with postoperative morphological changes in the nasal cavity, including the septum and inferior turbinate, is not clear. Study Design: The authors evaluated the three-dimensional relationship of the morphological changes in the inferior turbinate before and after surgery in 84 patients who underwent Le Fort I osteotomy. Three classifications were made according to superior amount of maxillary movement at the base of nasal cavity. Results: The high elevation group (4.0 mm or more) had 31 sides, the moderate elevation group had 93 sides, and the low elevation group (less than 2.0 mm) had 44 sides. The volume of inferior turbinate was 76.9 ± 12.8% of that before surgery in the high elevation group. The high- and moderate-elevation groups had significantly higher changes than the low elevation group, and the rate of contact between inferior turbinate and nasal cavity floor was 67.7%. Conclusions: After Le Fort I osteotomy, the volume of inferior turbinate tissue decreased in proportion to the amount of elevation of the maxilla. Although the soft tissue volume may be reduced due to adaptation of respiratory function, the inferior nasal passage was not completely ventilated in the high elevation group. If the elevation exceeds 4.0 mm counterclockwise with maxillary movement, it is necessary to consider the concomitant inferior turbinate resection because it may lead to nasal obstruction.

“…LFI is a widely used surgical procedure, with many reports on its prognosis and associated complications 1–3 . LFI has been reported to affect the midface region with changes in nasal soft tissue morphology, airflow, sinusitis, and structural changes in the nasal cavity 4–7 . LFI treats complex maxillary jaw deformations by multidirectional bone fragment movement according to the patient’s deformity.…”

[4][5][6][7] LFI treats complex maxillary jaw deformations by multidirectional bone fragment movement according to the patient's deformity. Nasal complications differ according to the movement of the bone fragments, and it has been reported that impacted movement of the maxilla results in narrowing of the nasal cavity.…”

This retrospective study aimed to evaluate the efficacy of support splint treatment for deformities and deviations of the nasal septum after Le Fort I osteotomy (LFI). Patients were divided into two groups: the retainer group wore a nasal support splint immediately after LFI for 7 days, and the no retainer group did not wear a nasal support splint. Evaluation was performed by measuring the ratio of the difference between the left and right sides of the nasal cavity area (ratio of nasal cavity) and the angle of the nasal septum using three computed tomography frontal images (anterior, middle, and posterior) before and one year postoperatively. Sixty patients were included and divided into two groups, the retainer and no retainer group (n = 30 each). Regarding the ratio of nasal cavity on middle images at one year postoperatively, the retainer and no retainer groups differed significantly (0.79 ± 0.13 and 0.67 ± 0.24, respectively; P = 0.012). The angle of the nasal septum on anterior images at one year postoperatively was 164.8 ± 11.7°in the retainer group and 156.9 ± 13.5°in the no retainer group, showing a significant difference (P = 0.019). This study suggests that support splint treatment after LFI is effective in preventing post-LFI nasal septal deformation or deviation.
