Abstract
OBJECTIVE
To verify the effect of orthognathic surgery (OS) on nasal dimensions and its correlation with respiratory symptoms in patients operated on over the past 20 years.
DESIGN
Retrospective study.
SETTING
Tertiary level craniofacial hospital.
PARTICIPANTS
535 patients with CLP previously repaired, without syndromes, age over 18, who performed OS between 2000 and 2019 and rhinomanometric evaluation pre and post OS.
INTERVENTIONS
Maxillary advancement isolated and combined with turbinectomy and/or mandibular osteotomy.
MAIN OUTCOME MEASURES
Minimum nasal cross-sectional area (CSA) assessed by posterior (PR) and anterior rhinomanometry (AR), nasopharyngeal cross-sectional area (NCSA) verified by modified AR, and self-perceived respiratory symptoms through a questionnaire.
RESULTS
After OS, there was a significant increase in CSA assessed by PR (p < .001) and AR (p < .001), while there was no significant difference in NCSA (p = 0.319). Regarding respiratory symptoms after OS, 26.3% showed improvement in nasal obstruction, 28.5% in oronasal breathing, 18.5% in snoring, and 5.2% in respiratory obstruction during sleep. However, a weak correlation between increased CSA and improvement of symptoms was observed. In the first decade, lower values of CSA (p < .001) and NCSA (p < .001) were observed compared to the second decade. Both periods showed a significant increase in CSA (p < .001).
CONCLUSIONS
Nasal dimensions and breathing symptoms were improved by OS when combined with turbinectomy. Comparing the results of patients operated on between two different decades, patients had more favorable conditions for breathing in the most recent decade of care. However, this was not statistically correlated with the improvement in patient symptoms in this study.
