| Popis: | Item does not contain fulltext This study aimed to assess the effects of bone-borne and tooth-borne surgically assisted rapid maxillary expansion on the volumes of the nose and nasal airway 2 yr after maxillary expansion. This prospective cohort study included 32 patients with transverse maxillary hypoplasia. Expansion was performed with a tooth-borne distractor (Hyrax) in 19 patients and with a bone-borne distractor [transpalatal distractor (TPD)] in the remaining 13. Cone beam computed tomography scans and three-dimensional (3D) photographs of the face were acquired before treatment and 22 +/- 7 months later, and were used to evaluate the volumes of the nose and nasal airway. Nasal volume increased by 1.01 +/- 1.6% in the Hyrax group and by 2.39 +/- 2.4% in the TPD group. Nasal airway volume increased by 9.7 +/- 5.6% in the Hyrax group and by 12.9 +/- 12.7% in the TPD group. Changes in the nasal volume and in the nasal airway volume between the pre- and post-treatment measurements were statistically significant, whereas differences between the treatment groups were not; 22 months after surgically assisted rapid maxillary expansion, the increases in the nasal volume and in the nasal airway volume were comparable between tooth-borne and bone-borne devices. |
