OBJECTIVE: This study aims to compare the effects of fast and slow expansion on nasal cavity structure. METHODS: A total of 40 patients were selected and randomly divided into two groups. Cone-beam computer tomography (CBCT) was obtained before and after surgery and used for comparing the changes in nasal structure before and after treatment. RESULTS: Fast expansion had resulted in greater changes in the basilar and nasal bone arch extension structures than slow expansion. No significant difference at maxillary width and nasal parenchyma. CONCLUSIONS: Rapid expansion therapy has more beneficial effects on nasal function.
