“…However, the authors argue that these results are associated with the small maxillary advancement necessary to correct the maxillary deformity in the evaluated patients. 32 In the present study, it was not possible to quantify the surgical movements performed during OS, limiting this type of analysis.…”

“…However, it must be considered that the pre and post-mean values indicated an unobstructed nasopharynx, with means greater than 0.790 cm 2 . 26 Likewise, Santiago et al (2016) 32 through cephalometric and volumetric analysis did not find statistically significant differences in the nasopharynx after OS. However, the authors argue that these results are associated with the small maxillary advancement necessary to correct the maxillary deformity in the evaluated patients.…”

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.

Context: Regarding the relationship between the size of the pharynx and several sagittal skeletal malocclusions and patterns of growth, contradictory findings have been documented. Aims: The intent of this research was to analyze the size of the pharynx in various sagittal malocclusions and growth patterns in the Nepalese population. Settings and Design: An analytic cross-sectional research was undertaken on patients who attended the Orthodontics Division of BPKIHS. Materials and Methods: A total of 135 patients’ lateral cephalometric radiographs were gathered. Medians and interquartile ranges of pharyngeal widths according to McNamara airway analysis and Arnett/Gunson FAB airway analysis adapted by Santiago et al. in different skeletal malocclusions and growth patterns were compared. Results: There was not any discernible statistically noteworthy variation within the upper pharynx size, lower pharyngeal width, nasopharyngeal width (WNP), oropharyngeal width, hypopharyngeal width (WHP), and deep pharyngeal width (WDP) in different skeletal malocclusions. A statistically significant variation was discovered in nasopharyngeal size (P = 0.010), hypopharyngeal size (P = 0.027), and deep pharyngeal size (P < 0.001) in various patterns of growth, i.e. hypodivergent versus normodivergent, and in hypodivergent versus hyperdivergent, not in normodivergent versus hyperdivergent group of patients. Conclusion: There was not anything statistically noteworthy variation in the pharyngeal widths of the participants with respect to the various skeletal malocclusions. WNP, WHP, and WDP showed a statistically significant variation between hypodivergent versus normodivergent and hypodivergent versus hyperdivergent growth patterns.
