“…Another potential side effect after RME could be the development of a dorsal hump, 5,17,18 which was not found in the patients in this study. The short-term nasal hard tissue change showed a significant increase in pyriform height and width, which was consistent with Badreddine et al, 10,11 Cordasco et al, 19 Palaisa et al, 20 and Fastuca et al 21 For the long term, this study examined how RME affected patients' nasal growth in comparison with the nontreatment CG. The differences between T1 and T3 values in the TG (D T1-T3, average 2.84 years) was compared with the differences between T1 0 and T3 0 in the CG (DT1 0 -T3 0 , average 2.25 years).…”

“…[43][44][45][46] In addition, CBCT allows the simultaneous evaluation of both skeletal and related soft tissue changes. Previously, studies used several different methods to evaluate nasal soft tissue changes, including photography, 5 in-person clinical measurements, 47 three-dimensional facial scans, 21 and tomography, 16 showing the wide range of outcomes. For those reasons, CBCT was used to assess the changes in the nasal soft and hard tissue in this study.…”

Objectives To evaluate nasal soft and hard tissue changes immediately post–rapid maxillary expansion (RME) and to assess the stability of these changes using cone beam computed tomography (CBCT). Materials and Methods A total of 35 treatment group (TG) patients (18 girls, 17 boys; 9.39 ± 1.4) had a pre-RME CBCT and a post-RME CBCT approximately 66 days after expansion, and 25 patients had a follow-up CBCT 2.84 years later. A total of 28 control group (CG; no RME) patients (16 girls, 12 boys; 8.81 ± 1.6) had an initial CBCT and a CBCT an average of 2.25 years later. Soft and hard tissue nasal landmarks were measured in transverse, sagittal, and coronal planes of space on CBCT scans. Differences within the same group were evaluated by paired t-tests or Wilcoxon signed-rank tests. Long-term comparisons between TG and CG were evaluated by independent-sample t-tests or Wilcoxon rank-sum tests. Results Immediately post-RME, there were statistically significant mean increases of 1.6 mm of alar base width, 1.77 mm of pyriform height, and 3.57 mm of pyriform width (P < .05). CG showed the significant increases over 2.25 years (P < .001). Compared with CG, the long-term evaluation of TG demonstrated only pyriform height and pyriform width showed a statistically significant difference (P < .01). Conclusions Although RME produced some significant increase on the nasal soft tissue immediately after expansion, it regressed to the mean of normal growth and development over time. However, long-term evaluation of TG compared with CG showed only pyriform height and pyriform width to be affected by RME.

“…Depending on the duration of this habit, the palate shape may change due to the pressure reduction in the nasal cavity, causing maxillary atresia. 25,26 The RME, when correcting the maxillary atresia, can cause changes in the nasal cavity, which is confirmed by the improvement of nasal permeability [27][28][29][30] and the passage of the respiratory flow. 31 Some patients evaluated here underwent RME (RAD and D) with the Hyrax® fixed expansion device because it is easy to install, has no acrylic support on the palate, and is easy to clean and adapt.…”

Aim: To evaluate the effects of rapid maxillary expansion (RME) on nasal patency in mouth breathing (MB) children with maxillary atresia due to or not due to allergic rhinitis (AR) associated with asthma. Methods: Fifty-three MB children/adolescents (aged 7–14 years) with mixed or permanent dentition and maxillary atresia participated, with or without unilateral or bilateral crossbite. They formed the groups: RAD (AR + asthma; clinical treatment, RME); RAC (AR + asthma; clinical treatment, no RME); and D (mouth breathers; RME only). RAD and RAC patients received topical nasal corticosteroid and/or systemic H1 antihistamine (continuous use) and environmental exposure control. All were evaluated before RME (T1) and 6 months after (T2) with the CARATkids score, acoustic rhinometry, and nasal cavity computed tomography (CT). Patients RAD and D underwent RME (Hyrax® orthopedic appliance). Results: A significant reduction in the CARATkids score occurred in the RAD (−4.06; p < 0.05), similarly when patient and parent/guardian scores were evaluated (−3.28 and −3.16, respectively). Acoustic rhinometry (V5) showed increased nasal volume in all groups, significantly higher in RAD patients than in RAC and D (0.99 × 0.71 × 0.69 cm3, respectively). CT of the nasal cavity documented increased volume in all three groups, with no significant differences between them. Conclusion: In MB patients with AR, asthma, and maxillary atresia, RME increased nasal cavity volume and improved respiratory symptoms. However, it should not be used as the only treatment for managing patients with respiratory allergies.

“…Orthodontists have perceived the chin prominence more than other groups, as they probably are more sensitive in their judgment due to their training. Their assessments are based more on objective guidelines and ideal relationships, unlike the laity who are influenced by the culture of beauty [17,22,23]. In the last century, a prominent chin is considered an attractive male characteristic, especially in association with large, prominent lips [23][24][25][26][27].…”

Background: The perception of facial aesthetics is a complex topic due to its subjective nature and it can be influenced by several factors. The purpose of this study was to compare the perception of general dentists, orthodontists, maxillofacial surgeons, and lay people by evaluating facial aesthetics in skeletal class III patients, especially for maxillary sagittal position. Methods: A survey consisting of three sets of pre-treatment photographs of four dysmorphic patients was used. The questionnaire was submitted to a total of 200 participants divided into the following four subgroups: general dentists, orthodontists, maxillofacial surgeons, and lay people. Their opinion on facial disharmony, sagittal position of the jaws, asymmetry of the chin, projection of the cheekbone area, and lip aesthetics was recorded. Results: Significant differences were found between experts and non-experts in the perception of the maxillary position, asymmetry of the chin and zygomatic area (p < 0.01). No statistically significant differences were found among the groups in the perception of mandibular position and lip aesthetics. Conclusion: The respondents with a medical or dental background perceived the presence of maxillary retrusion more than others. Only orthodontists and maxillofacial surgeons have recognized an alteration of the middle facial third as a greater component of skeletal class III malocclusion.
