“…Tomohisa et al 20 classified the positions of nasal septal deviations into 3 categories: anterior, middle, and posterior, he pointed out that classified the positions of nasal septal deviations into 3 categories: anterior, middle, and posterior. Massie et al 18 used a similar method to divide the position of the nasal septal deviation into 2 types anterior and posterior, and got similar results. In our study most sever deviations were discovered in middle part of nasal septum in both coronal and transverse level.…”

“…In addition, CBCT shows plenty of advantages, such as low radiation dose, isotropic voxel size, and easy accessibility. 18 The maxillary sinus varies with the age of the patients, which leads to a bias when we talk about the asymmetry. Angle of septal deviation and RSA were commonly used parameters in previous studies to evaluate the degree of the nasal septal deviation 6,17,19 These kinds of parameters using angle or ratio to manifest degree of asymmetry avoid the bias caused by individual difference.…”

To quantitatively evaluate the relationship between nasal appearance and nasal septum deviation in unilateral complete cleft patients using cone-beam computed tomography.Method: Cone-beam computed tomography images of 180 patients with unilateral cleft lip/palate from June 2014 to June 2017 were used in the study. None of the subjects had undergone septoplasty. The data were compared between the 2 groups to elucidate the relationship between nasal appearance and deviated nasal septum in unilateral complete cleft patients. Results: The mean age of a total of 180 patients (126 males and 54 females) was 14.58 years, with a standard deviation of 7.10 years, ranged from 6 years old to 49 years old. Columella nasi symmetry parameters show slight positive significant association with angle of nasal septal deviation on transerve plan (r ¼ 0.250, P < 0.001), TRSD (r ¼ 0.323, P < 0.001) and coronal range of nasal septal deviation (r ¼ 0.294, P < 0.001), and moderate positive significant association with coronal angle about septal deviation (r ¼ 0.404, P < 0.001) Conclusions: Columella nasi symmetry affected by septal deviation, whereas there is lack of evidence to say symmetry of nasal tip and base affected by septal deviation. The symmetry of nasal tip and alar base are not just determined by nasal septum deviation. The nasal septum deviation show difference in different cleft type.

“…CBCT was also used to evaluate maxillary expansion in CLP patients [6,[30][31][32][33][34][35][36]. Moreover, CBCT was also used in various anatomical studies related with CLP patients: 1) Three-dimensional (3D) analysis of craniofacial structures [3,29,37], and of facial asymmetry [29,38,39]; 2) mandible [3,29,40,41]; 3) sella turcica [42]; 4) pharyngeal airway volume [3,[43][44][45][46][47][48]; 5) cortical bone thickness around the cleft area [26,27,29,49]; 6) palatal morphology and soft tissue depth [6,28,29,50,51]; 7) maxillary sinus volume [29,52,53]; 8) nasal morphology [3,29,54], and nasal airway [55]; 9) canine eruption through the alveolar graft bone [3,4,6,7,27,…”

Objective: to present and to illustrate a new methodology for daily practice in cone beam computed tomography (CBCT) interpretation and reporting in cleft lip palate (CLP) non syndromic paediatric patients. The proposed protocol is based on clinical experience and on systematic search of the literature. Material and methods: We performed two types of systematic search of articles: 1) articles related to the use of CBCT in CLP patients, and 2) articles related to the reporting and interpretation of the CBCT images by radiologists. We used two databases PubMed and Google scholar. Results: For indications of CBCT in CLP patients we found in PubMed 378 articles and 48 articles were selected for the review; in Google scholar we found 463 articles, and 9 articles were selected for the review. 2) For reporting in CBCT we found 956 articles in PubMed, and 9 articles were selected for the review. Conclusions: We presented the 6-steps system for interpretation and reporting information from CBCT of CLP paediatric patients: 1) Step 1 (axial view): presence or absence of bone bridge remnants of alveolar bone graft; Step 2 (3D dental tissue reconstruction): description of dental arch tooth by tooth, search for agenesis and supernumerary teeth, description of variation in the position of the tooth explaining the type of existing translation and rotation; Step 3 (coronal view): cleft palate pathway and its extension; anomaly in maxillary, ethmoid and sphenoid sinuses if existing; Step 4 (sagittal and coronal view): checking of the opening (calcification sites) of the sphenooccipital synchondrosis, and checking of anomalies of the occipital bone; Step 5 (3D bone tissue reconstruction): C1-C2 vertebra anomalies; Step 6 (3D soft tissue reconstruction): external ear anomalies. We illustrated our methodology with 46 figures from 5 CBCT of CLP patients.

“…The diversity of study models, evaluation times, size and heterogeneity of the samples, different protocols performed, and poorly detailed descriptions of the methods make it difficult to safely evaluate studies that use the NAM protocol 13 . Among the methods used by studies to assess the effects of NAM therapy are the use of 2-dimensional images, 7,10,14,16,17 and even 3-dimensional records 18–24 . Results of the studies have shown improvement in the aesthetics of the nose, lip, alveolar bone, palate, and nasal wings 14 .…”

The study aimed to evaluate the effect of nasoalveolar molding (NAM) therapy through reverse engineering, or its absence, to obtain symmetry of the face and maxillary arch. Twenty-six babies with unilateral cleft lip and palate received treatment with NAM, and 12 babies with unilateral cleft lip and palate without presurgical orthopedics (control group). Patients were molded and photographed in 2-stages: the first month of life (T1/pre) and after the use of NAM/before the cheiloplasty (T2/post). In the digital models, the analyses performed were arch perimeter, arch length, and labial frenulum angle. The photographs allowed us to analyze nasal width, mouth width, columella angle, and nostril area. The results demonstrated that there was an increase in arch perimeter and arch length in control and NAM groups in the T2 period in comparison to T1. Labial frenulum angle was reduced in the NAM group compared to the NAM-T1 and control-T2 periods. Treatment with NAM yielded a reduction in nasal width in the period of T2 compared with T1. Columella angle was enhanced after NAM use in T2 and, was different from control group. The nostril area was reduced in the NAM group in T2 compared with control group. Nasoalveolar molding therapy reduced the labial frenulum angle, contributing to a reduction in the extension of the cleft. The NAM protocol improved facial symmetry, mainly through nasal effects, whereas the absence of orthopedic therapy yielded a commitment to the face and maxillary arch symmetry.
