Abstract
INTRODUCTION Orthognathic surgery can lead to sinus alterations, including sinusitis, attributed to the exposure of maxillary sinuses during Le Fort I osteotomy. Furthermore, being a hospital-based procedure, there is potential risk of complications arising from bacteria prevalent in such environments. This study evaluated maxillary sinusitis occurrence and the presence of multidrug-resistant bacteria in the nasal cavity before and after orthognathic surgery. METHODS Ten patients with dentofacial deformities underwent Le Fort I osteotomy. Clinical evaluations using SNOT-22 questionnaire were performed, and nasal cavity samples were collected pre-surgery and 3-6 months post-surgery to quantify total mesophilic bacteria and detect Staphylococcus aureus, Acinetobacter baumannii, and Klebsiella pneumoniae. Cone Beam Computed Tomography (CBCT) was performed pre- and post-operatively, and the results were evaluated using the Lund-Mackay system. This study was registered and approved by the Research Ethics Committee of PUCRS (No. 4.683.066). RESULTS The evaluation of SNOT-22 revealed that five patients showed an improvement in symptoms, while two remained in the same range of interpretation. One patient developed post-operative maxillary sinusitis, which was not detected at the time of evaluation by SNOT-22 or CBCT. CBCT showed a worsening sinus condition in three patients, two of whom had a significant increase in total bacteria count in their nasal cavities. The Brodsky scale was used to assess hypertrophy in palatine tonsils, where 60% of the subjects had grade 1 tonsils, 20% had grade 2 and 20% had grade 3. None of the patients had grade 4 tonsils, which would indicate more than 75% obstruction. Two patients harboured S. aureus and K. pneumoniae in their nasal cavities. Notably, K. pneumoniae, which was multidrug-resistant, was present in the nasal cavity of patients even before surgery, but this did not result in maxillary sinusitis, likely due to the patients' young and healthy condition. CONCLUSION There was an improvement in signs and symptoms of maxillary sinusitis and quality of life in most patients after orthognathic surgery. However, some patients may still harbour multidrug-resistant bacteria, even if they are asymptomatic. Therefore, a thorough pre-operative assessment is essential to avoid difficult-to-treat post-operative complications.

Evaluation of Related Factors of Maxillary Sinusitis After Le Fort I Osteotomy Based on Computed Tomography: A Retrospective Case-Control Study. J Craniofac Surg 2022; 33:1795-1799. [PMID: 34980838 DOI: 10.1097/scs.0000000000008450] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2021] [Accepted: 11/30/2021] [Indexed: 11/26/2022] Open
Abstract
ABSTRACT Maxillary sinusitis is 1 of the postoperative complications of the Le Fort I osteotomy, this study investigated the related factors of maxillary sinusitis after Le Fort I osteotomy. A total of 23 cases, 92 controls, and 11 related factors were included in this case-control study with a 1:4 case-control ratio. The risk factors for maxillary sinusitis after Le Fort I were examined by least absolute shrinkage and selection operator multivariate conditional logistic regression and least absolute shrinkage and selection operator multivariate linear regression. The patency of maxillary sinus ostium at 6 months after surgery was significantly associated with maxillary sinusitis after Le Fort I osteotomy. Compared with the obstructed maxillary sinus ostium, the percentage of the volume of the healthy air cavity in the complete sinus cavity increased 70.7% when the maxillary sinus ostium was unobstructed, and 95% confidence interval was 0.610 to 0.805. Similarly, when the maxillary sinus ostium was wide, the percentage increased 6.0% compared with the narrow 1, and 95% confidence interval was 0.013 to 0.107. This study indicated that the patency of maxillary sinus ostium has an important impact on maxillary sinusitis after Le Fort I osteotomy. Close attention should be paid to maintain the maxillary sinus ostium and the drainage of maxillary sinuses unobstructed in a clinical setting.

Abstract
Orthognathic surgery including Le Fort I osteotomy involves changes in the nasal septum and maxillary sinus. This study assesses nasal septum changes after Le Fort I osteotomy using cone beam computed tomography images and evaluates mucosal changes in the maxillary sinus after the surgery.This was a retrospective study of 33 patients who underwent orthognathic surgery including Le Fort I osteotomy. To assess the maxillary sinus, changes in the mucosa of the maxillary sinus were analyzed by volume and geometry. We measured the air cavity per se and mucosal thickening of the maxillary sinus using SIMPLANT (Materialise, Belgium) software. And the geometry of the distribution of the mucosa was analyzed using cone beam computed tomography images.The septal angle was decreased after surgery, but not significantly (P > 0.05). The volume reduction of the air cavity per se and the volume increase associated with mucosal thickening were statistically significant (P < 0.05). Mucosal thickening was observed in the posterior-inferior direction.In this study, nasal septum deviation was not statistically significant after Le Fort I osteotomy. Decrease of the air cavity per se, decrease of the total volume of the maxillary sinus, and increase of mucosal thickening were prominent. Furthermore, the mucosal thickening that occurs after surgery appears to be mainly in the posterior lower part of the maxillary sinus.

Abstract
PURPOSE The total maxillary alveolar osteotomy (TMxAO) is not commonly used to manage maxillary skeletal deformities. This article describes the technique, reviews its stability, and discusses its advantages over the more popular Le Fort I osteotomy. MATERIALS AND METHODS A series of 177 TMxAO patients satisfying the inclusion criteria from a cadre of 234 patients undergoing TMxAO between 1985 and 1993 were evaluated in a retrospective cohort study regarding achievement of predicted anatomic movements, stability of skeletal results, and preservation of inter-alar dimension. The patients were evaluated early postoperatively and at 11 to 14 months postoperatively, and the data were exposed to the Shapiro-Wilk test and analysis of variance and analyzed using SPSS software (version 21; IBM, Armonk, NY) at the 99% level of confidence (P ≤ .01). RESULTS Only in 58% of patients did the designed millimetric study model changes correspond precisely to the millimetric changes disclosed in a comparison of preoperative and early postoperative cephalograms. Comparison of early and late postoperative cephalograms, with infrequent exceptions, described millimetric instabilities of less than 2 mm and angular instabilities of less than 2°. Despite 2 significant outliers, the average inter-alar instability as determined by direct measurement was 0.19 mm. CONCLUSIONS This study suggests that the TMxAO compares favorably in stability with the Le Fort I osteotomy as recorded in the literature and, in terms of versatility, mobility of segments, avoidance of anatomic hazard, and preservation of nasal width, offers advantages in comparison.
