This study investigated the correlation between skeletal features and nasal airflow- and olfaction-related problems in 68 patients. Malocclusion in children, caused by skeletal mandibular protrusion and smaller maxilla, was associated with reduced olfaction. The study found that maxillary development may influence olfaction in children, and changing maxillofacial morphology could potentially improve olfactory function.
Objectives: Functional problems, including nasal flow problems, are associated with specific skeletal and dental features. Further, maxillary expansion has been associated with nasal airway resistance alterations. This study aimed to investigate whether there is a correlation between skeletal features and nasal airflow- and olfaction-related problems. Materials and methods: This prospective study included 68 patients (30 boys, 38 girls; mean age 9 +/- 2 years) examined at the Ohu University Hospital. We classified patients into three skeletal Classes (Class I, II, and III) based on the ANB angle. Olfactory disorder history was collected from the guardians. Maxillofacial measurements, nasal airflow assessments, and olfactory tests were performed using cephalometric analysis, rhinomanometry, and T&T olfactometer, respectively. Results: Malocclusion, resulting from skeletal mandibular protrusion and smaller maxilla, was associated with reduced olfaction in children. The detection and recognition thresholds of skeletal Class III were significantly higher than those of Classes I (p= .01) and II (p= .01). Significant correlations were observed between SNA and the detection threshold (r= -.50) as well as between nasion perpendicular-point A and the recognition threshold (r= -.53). The detection and recognition thresholds were significantly higher in Class III than in Classes I (r= .3) and II (r= -.1). Conclusions: Maxillary growth and development may be associated with olfaction in children. Changing the maxillofacial morphology may improve olfactory function. In the future, we will investigate how malocclusion treatment affects olfactory function.
