Aim: The study tests the correlation between the enlargement of the nasal cavity width, interglenoid fossa distance, and intercondylar distance after rapid maxillary expansion (RME) in growing patients. Materials and methods: Cone beam computed tomography (CBCT) was performed for 25 patients presenting a bilateral crossbite (11 males, 14 females, and mean age 11.6 ± 1.6 years) at baseline (T0) and at 6 months after RME (T2), T1 being the end of expander activation. Images were digitized for linear measurements using specific software. Values were compared at the nasal width, interglenoid fossa distance, and intercondylar distance to test the correlation in the transverse dimension. Results: At T0, a correlation already existing between the interglenoid fossa distance and the intercondylar distance persisted at T2. The correlation between the nasal cavity width and interglenoid fossa distance nonexistent at T0 ended toward statistically significant at T2. Additionally, the lateral position of the condyles was not correlated with the nasal cavity width neither at T0 or T2. Conclusion: A correlation between the interglenoid fossa distance and intercondylar distance was exhibited 6 months after RME. The correlation between the nasal cavity width and interglenoid fossa distance was close to significant at T2.
