“…All of the earlier research evaluation techniques were based on frontal facial photographs. [ 15 16 17 ] No consideration was given to the severity of nasal septal deviation or how it is related to facial asymmetry. One of the most useful diagnostic tools for assessing asymmetry is the posterior-anterior cephalogram.…”

Introduction: The nasal septum is crucial in the development of the craniofacial structures. Deviated nasal septum is one of the anatomical causes of mouth breathing which in turn lead to malocclusion. Aims and Objectives: To evaluate the dentofacial and cephalometric characteristics in individuals with nasal breathing obstruction brought on by nasal septal deviation, as well as the relationship between these defects and various malocclusions and the degree of facial asymmetry. Materials and Methods: A two-point evaluation was adopted for the selected patients, one at the ENT department using clinical examination and CT–PNS and the severity classified according to the Mladina classification and another at the dental department, using clinical examinations, PA cephalograms, lateral cephalograms, and facial photographs. Results and Discussion: The association between malocclusion and various grades of septal deviation was statistically significant with a P value of 0.006. Results showed that 13 patients are with Class I skeletal pattern, 20 patients with Class II, and 7 patients with Class III skeletal pattern. None of the grade 7 nasal septal deviation patients had class I malocclusion and none of the grade 2 nasal septal deviation patients had class III malocclusion. Class II division I malocclusion was the most common type noted in patients with nasal septal deviation. Grade 7 nasal septal deviation was associated with the maximum amount of ANS and mentioned deviation indicating significant facial asymmetry. Conclusion: Class-II Division-1 malocclusion was the most common type noted and Class III malocclusion was more common in higher grades of nasal septal deviation. Maxillary and mandibular asymmetry worsens significantly with an increase in the grade of nasal septal deviation and is one of the significant factors in causing facial asymmetry.

“…Additionally, a deviated growth pattern of the nasal septum is a significant factor in the development of skeletal and dental asymmetry. Asymmetric growth of the nasal septum can result in facial skeletal asymmetries, suggesting that the human nasal septum may serve as a growth center for the face [15,16]. Although many studies have investigated nasal septal deviation and expansion [17][18][19], there is no available data on how the maxillary segments move in the different genders.…”

Nasal septal deviation (NSD) is one of the most common abnormalities impacting the maxillofacial development of children. Herein, we investigated the impact of orthopedic rapid maxillary expansion (RME) on the nasomaxillary complex and NSD in pediatric patients. The study sample consisted of a total of 40 patients divided into two groups. The experimental group included 26 patients (13 females and 13 males) with skeletal maxillary transversal constriction and NSD greater than 1 mm, while the control group comprised 14 patients (6 females and 8 males) with skeletal maxillary transversal constriction but no NSD. All the patients were treated for approximately 15 days with the tooth-tissue born RME device. The activation procedure was to turn the transversal Hyrax screw a quarter turn, twice a day. After that, the device was left in place for a period of five months to facilitate passive retention. Radiographic analysis was performed on posteroanterior (PA) cephalometric radiographs taken at pre-expansion (T1) and post-expansion (T2). The data were evaluated using the Mann-Whitney U and Wilcoxon Sign tests. The experimental group showed a statistically significant decrease (p < 0.05) in the distance from the axis of symmetry to middle of nasal septum (SNM-mid) and to inferior part of the nasal septum (SNI-mid) measurements, indicating a reduction in NSD. Additionally, both experimental and control groups showed a statistically significant increase (p < 0.05) in maxillofacial measurements, including the distance between the nose length (X-SNM and SNM-SNAC), width of the nasal cavity (Pir L-R), basal maxillary width (Mx L-R), vestibular cuspid of upper first molars (CVM + L-R) and lower first molars (CVM-L-R). Based on the study findings, RME was considered effective in achieving craniofacial improvement in pediatric patients with NSD, which positively impacted their healthy growth and development. The improvement in the nasomaxillary complex was similar between genders.

Objectives The study aims to conduct a bibliometric analysis on maxillary skeletal expansion to elucidate the evolution and current status and predict future research hotspots and trends. Material and methods A search was conducted in the Web of Science Core Collection at the University of Hong Kong’s electronic library using the query “(TS = maxillary expansion) AND (TS = skeletal expansion).” The resulting literature data were imported into CiteSpace 6.2.R4 and VOS viewer software to analyze authorship, countries, institutions, keywords, etc. Results A total of 923 articles were analyzed. The research in this field has shown a steady growth, with a significant increase since 2019. The USA and Italy have played prominent roles in contributing to the publication volume and strengthening collaborative exchanges. Clustering labels provide directions for in-depth analysis of the literature. Conclusions (1) MARPE (miniscrew-assisted rapid palatal expansion) and SARME (surgically assisted rapid maxillary expansion) have gained widespread attention and become research hotspots due to their applicability in adults whose growth and development have ceased, while still producing favorable skeletal effects. (2) In addition to widening the maxillary arch, maxillary expansion techniques have shown significant effects on increasing nasal cavity width and volume. However, there is still controversy regarding whether they can effectively improve the deviated nasal septum. (3) Maxillary skeletal expansion techniques have been shown to increase upper airway volume and improve breathing, making them potentially valuable in the treatment of obstructive sleep apnea (OSA). Clinical relevance This study can provide cutting-edge clinical recommendations for healthcare professionals to better formulate clinical strategies.
