Mudanças no septo nasal em pacientes submetidos a osteotomia le fort i através da intubação nasotraqueal tradicional x dupla intubação nasal

Abstract

Orthognathic surgery has the objective to correct dentoskeletal discrepancies and improve facial balance and harmony, maximizing treatment benefits. Soft tissue profile’s morphology might be the key on decision-making about dentoskeletal changes. First choice treatment to surgical repositioning of the maxilla is Le Fort I osteotomy. Nevertheless, nasal septum deviation may be a transoperatory complication, when the nasal endotracheal tube obstructs the operative field. The use of a second tube in the contralateral nostril is an alternative to maintain the nasal symmetry. Until now, no study evaluated nasal dimensions after maxillary Le Fort I osteotomy using double intubation. Therefore, the objective of this study was to assess and compare nasal cavity dimensions and symmetry before and after Le Fort I osteotomy using conventional or double intubation during general anesthesia. The sample included 24 patients with pre- and posttreatment cone beam computed tomography (CBCT) available. Patients were split in two groups by intubation technique: group I, conventional intubation; group II, double intubation. Scans were imported to the Dolphin software, images were reoriented and measures from the nose and nasal cavity were performed. Data were compared between groups with non-parametric Wilcoxon test (p < 0.05). The results indicated no statistically significant differences between groups (p > 0.05). Under limitations of the study, it is possible to conclude that Le Fort I osteotomy has equal outcomes in the nose and nasal cavity using either conventional or double nasal intubation
