Changes in Nasal Function after Maxillary Displacement were Evaluated in Rhinoplasty Candidate Patients

Introduction: According to previous studies, it is impossible to predict the functional parameters of the nose for each patient after maxillary surgery; But other studies have offered different hypotheses. Due to some discrepancies in the results of previous studies, in the present study we decided to evaluate nasal function by rhinomanometric tests before and after surgery according to the type of maxillary displacement. Material and Methods: This descriptive and longitudinal self-control study was performed during 2019 with the participation of rhinoplasty patients referred to Imam Reza Hospital in Tabriz. Changes in nasal function after maxillary displacement were evaluated in rhinoplasty candidate patients.Results: In all samples (regardless of group), the mean airflow in the tail was increased after surgery compared to before surgery, but the amount of increase was not significant. The mean airflow on exhalation was also increased after surgery compared to before surgery, but the amount of increase was not significant. The mean air resistance in the tail was reduced after surgery compared to before surgery, but the amount of reduction was not significant. The mean air resistance on exhalation was also decreased after surgery compared to before surgery, but the amount of reduction was not significant.Conclusion: It seems that if Lefort s osteotomy is performed in rhinoplasty surgery with the correct technique, it will not cause respiratory problems for the patient. However, more extensive studies are needed for a more accurate assessment.
