Resumo: |
Introduction: To evaluate the effects of rapid maxillary expansion (RME) in the soft tissues of patients with and without cleft lip and palate using cone beam computed tomography (CBCT). Materials and Methods: CBCT were selected from 60 patients with ERM divided into two groups. Group 1: 30 patients without cleft (9 boys and 21 girls; ± 10.7 years) and Group 2: 30 cases with cleft (18 boys and 12 girls; ± 10.0 years). CBCT were performed at T1, before the ERM, and T2 after RME. The CBCT images were analyzed in OsiriX MD software (FDA approved, version 1.4.2; Pixmeo, Geneva, Switzerland ) according to the following variables: superior nasal width (Mfd - Mfe), nose base width (Cad- Cae), alare width (Ald Ale), columella width (Nstd- Nste), nose base length (Sn - Prn), right nasal cavity width (Cned- Cnid), left nasal cavity width (Cnee- Cnie), columella length (Sn - Cl), nasolabial angle (ANL). Results: data were evaluated by student's t test and the Mann-Whitney nonparametric test with a significance level of 5%. Significant difference on the soft tissues width of the nose were demostrated for both groups after RME. Conclusion: there was an increase on the soft tissues width of the nose after the RME in both groups and differences were greater in the group without cleft in T2. |
