Assessment of the effect of deviated nasal septum on the structure of nasal cavity

Abstract

The present study was aimed to investigate the effects of DNS on the structure of nasal cavity. The paranasal sinus coronal view CT of 108 patients with DNS and 129 hospitalized patients without DNS was retrospectively analyzed. The transverse diameter of nasal cavity (a), transverse diameter of nasal cavity and paranasal sinus (b), angle between maxillary and palatal bone, interalveolar distance, and maxillary rotation distance were measured. The ratio of a/b in experimental group was 0.367 ± 0.006 which was significantly (P = 0.0023) less than that in control group (0.391 ± 0.005). For the angle between maxillary and palatal bone, there was no significant difference found between DNS and control group for both right and left sides. The interalveolar distance was 40.75 mm in experimental group, and 38.8 mm in control (P = 0.0002). For the maxillary rotation distance, findings were considered as significant (P < 0.0001) in experimental group (11.25 mm) compared with control (10.1 mm). The present study demonstrates that long-term DNS affects the development of nasal cavity and paranasal sinus, as well as increases the interalveolar distance and maxillary rotation distance. These influences may be caused by the alteration of airflow inside the nasal cavities.

Nasal Septum Deviation as the Consequence of BMP-Controlled Changes to Cartilage Properties

“…Nasal septum deviation (NSD) that describes a non-straight, deformed nasal septum is a common abnormality and can be observed in 80% of the population ( Serifoglu et al, 2017 ). NSD might be inconspicuous but frequently is associated with various degrees of nasal airway obstruction resulting in Sleep Disordered Breathing (SDB) ( Wang et al, 2016 ; Alsufyani et al, 2017 ; Mandour et al, 2019 ). Congenitally acquired deviation frequently develops during time of rapid midfacial growth and is associated with reduced midfacial growth and a strong predisposition for SDB ( D’Ascanio et al, 2010 ).…”

Relationship between the degree and direction of nasal septum deviation and nasal bone morphology

“…The nasal septum is located in the medial portion of the nasal cavity and it is on the major part of the nose structure. It is divided into a posterior part by the vomer and perpendicular plate of the ethmoid bone and an anterior part by the quadrangular cartilage [ 1 , 2 ].…”

“…When we consider healthy nasal respiration the anatomical and morphological characteristics of the bony and cartilaginous parts of the nasal septum play an important role. Nasal septal deviation is also linked to sleep apnea, repetitive sneezing, nosebleeds, sinusitis and difficulty breathing [ 1 ]. Some investigators linked the sense of smell sense with septal deviation.…”

“…In the growth period, the nasal septum acts as a growth plate that affects surrounding bones and facial skeletal tissues [ 6 ]. Thus, nasal septum deviation affects facial morphologic parameters such as interalveolar distance and maxillary rotation distance, causing compensatory changes in the lateral nasal wall and septal deviation, which are associated with nasal floor and palatal region asymmetries [ 1 , 6 , 7 ]. The severity of septal deviation also affects the ipsilateral lateral lamina of the cribriform plate width and ipsilateral middle turbinate length [ 8 ].…”

Prevalence and Correlation of Nasal Septum Deviation, Concha Bullosa and Maxillary Sinusitis in a Group of Adult Egyptian Population: A Retrospective CBCT Study

“…According to the literature, NSD occurs secondary to trauma during intrauterine life, birth, or any time during life 7 . It is reported that NSD may be related to sleep apnea, nosebleeds, repetitive sneezing, difficulty in breathing, and chronic sinusitis 8 . The deviation of the nasal septum causes change in the air flow in the nasal cavity, nasal cycle and mucociliary clearance.…”
