Özet

Objective: To evaluate the effects of rapid maxillary expansion (RME) on the vocal quality, maxillary central incisors, midpalatal suture, and nasal cavity in patients with maxillary crossbite. Materials and Methods: Coronal CT scans of 30 subjects (14 boys, 16 girls; mean age, 12.01 6 0.75) were taken before RME (T0), and at the end of the expansion phase (T1). Voice samples of all patients were recorded with a high-quality condenser microphone (RODE NT2-A) on a desktop computer at T0 and T1. Statistical analyses were performed using a paired-sample t-test. The degree of association between the changes in the voice parameters and nasal width was assessed with Pearson's correlation. Results: RME treatment produced a significant increase in the transverse dimensions of the midpalatal suture and nasal cavity between T0 and T1 (P, .05). The maximum F0 and jitter (%) results were shown to decrease statistically significantly from T0 to T1 (P, .001 and P ¼ .042, respectively). Between T0 and T1, shimmer (%) and shimmer (dB) exhibited statistically significant increases (P ¼ .037 and P ¼ .019, respectively). Conclusions: After RME therapy, voice quality differences were found to be associated with increases in nasal width.
