“…Nasal septum deviation is classified based on the type of shape changes ( Teixeira et al, 2016 ; Taghiloo and Halimi, 2019 ). Some forms of NSD result from uncoordinated growth of the septum and its articulating structures (vomer, ethmoid, nasal bones) resulting frequently in facial asymmetries.…”

The nasal septum cartilage is a specialized hyaline cartilage important for normal midfacial growth. Abnormal midfacial growth is associated with midfacial hypoplasia and nasal septum deviation (NSD). However, the underlying genetics and associated functional consequences of these two anomalies are poorly understood. We have previously shown that loss of Bone Morphogenetic Protein 7 (BMP7) from neural crest (BMP7ncko) leads to midfacial hypoplasia and subsequent septum deviation. In this study we elucidate the cellular and molecular abnormalities underlying NSD using comparative gene expression, quantitative proteomics, and immunofluorescence analysis. We show that reduced cartilage growth and septum deviation are associated with acquisition of elastic cartilage markers and share similarities with osteoarthritis (OA) of the knee. The genetic reduction of BMP2 in BMP7ncko mice was sufficient to rescue NSD and suppress elastic cartilage markers. To our knowledge this investigation provides the first genetic example of an in vivo cartilage fate switch showing that this is controlled by the relative balance of BMP2 and BMP7. Cellular and molecular changes similar between NSD and knee OA suggest a related etiology underlying these cartilage abnormalities.

“…Bayrak et al [ 43 ] reported that there was no correlation between nasal septum deviation and SMT. Meanwhile, Taghiloo and Halimi [ 44 ] investigated changes in SMT based on differences in nasal septum deviation type and showed that there was no difference based on nasal septum deviation type, but increased SMT was observed in 31.76% and 56.67% of males and females with nasal septum deviation, respectively, and there was a significant relationship between nasal septum deviation and thickening of maxillary sinus mucosa. Furthermore, research based on CBCT by Shanbhag et al [ 24 ] showed that ostium obstruction was observed in 13.1% of patients, and that there was a correlation with SMT.…”

Factors influencing the sinus membrane thickness in edentulous regions: a cone-beam computed tomography study

Background During implant treatment in the maxillary molar area, maxillary sinus floor augmentation is often performed to ameliorate the reduced alveolar bone height attributable to bone remodeling and pneumatization-induced expansion of the maxillary sinus. However, this augmentation may cause complications such as misplaced implants, artery damage, and maxillary sinus mucosal perforation; infections like maxillary sinusitis; and postsurgical complications such as bone graft leakage and postoperative nasal hemorrhaging. To reduce the complications during maxillary sinus floor augmentation and postoperative infections, we performed retrospective investigations of various systemic and local factors that influence pre-operative sinus mucosal thickness (SMT) by using cone-beam computed tomography (CBCT). Subjects included patients who underwent maxillary sinus floor augmentation in an edentulous maxillary molar area with a lateral approach. Pre-operative SMT, existing bone mass, and nasal septum deviation were measured using CBCT images. Relationships between SMT and the following influencing factors were investigated: (1) age, (2) sex, (3) systemic disease, (4) smoking, (5) period after tooth extraction, (6) reason for tooth extraction, (7) residual alveolar bone height (RBH), (8) sinus septa, and (9) nasal septum deviation. Correlations were also investigated for age and RBH (p < 0.05). Results We assessed 35 patients (40 sinuses; 11 male, 24 female). The average patient age was 58.90 ± 9.0 years (males, 57.9 ± 7.7 years; females, 59.9 ± 9.4 years; age range, 41–79 years). The average SMT was 1.09 ± 1.30 mm, incidence of SMT > 2 mm was 25.0%, incidence of SMT < 0.8 mm was 50.0%, and the average RBH was 2.14 ± 1.02 mm. The factors that influenced SMT included sex (p = 0.0078), period after tooth extraction (p = 0.0075), reason for tooth extraction (p = 0.020), sinus septa (p = 0.0076), and nasal septum deviation (p = 0.038). Conclusions Factors associated with higher SMT included male sex, interval following tooth extraction < 6 months, periapical lesions, sinus septa, and nasal septum deviation. Factors associated with SMT > 2 mm were sex and reason for tooth extraction, while factors associated with SMT < 0.8 mm were time following tooth extraction and nasal septum deviation. Despite the limitations of this study, these preoperative evaluations may be of utmost importance for safely conducting maxillary sinus floor augmentation.

The nasal septum separates the right and left part of the nasal cavity and columellar septum, membranous septum and septum proper are the parts of it. Deviation of nasal septum is a common case of nasal obstruction presented in a clinic. A lot of classifications have been developed to help ease the study of deviated nasal septum but none of them is used as a standard. Some of the classifications include the one given by Vidigal, Guyuron, Cerek, Mladina and Cottle’s. Apart from nasal obstruction other common clinical features involving deviated nasal septum are sinusitis especially in horizontal deviation type V. Pressure on lateral wall by spurs can also cause pressure headache. Due to increased air flow in the nasal cavity, dryness occurs causing epistaxis. Obstruction of nasal cavity causes mouth breathing in return either exaggerating or leading to obstructive sleep apnoea. Septal deviation also effects the choroidal thickness and choroidal blood supply. Histopathologically, lymphocytic infiltration and squamous metaplasia occurs in septal mucosa. These changes occur mostly due to change in the aerodynamic flow. There is decreased cilia movement and inferior turbinate hypertrophy. Thickness of inferior turbinate gains importance while septoplasty as, if thickened a lot, the inferior turbinate demands excision. The deviated nasal septum is associated with sinusitis, chronic suppurative otitis media and Eustachian tube dysfunction. Management involves sub mucus resection or septoplasty. Out of the two, septoplasty is preferred as it is a conservative surgery. Only symptomatic and cosmetically grossly disfigured cases require a surgical treatment while the asymptomatic cases are generally not indicated for surgery. This study tries to review the Classification, Clinical Features and Management of Deviated Nasal Septum.
