Nasal Septal Deviation Clinical Trial
Official title:
The Relationship Between the Direction and Degree of Nasal Septal Deviation and Nasal Bone Morphology
The aim of the study is to evaluate the relationship between the direction and degree of nasal septal deviation with nasal bone morphology , along with factors such as age and gender.
The nasal septum is located in the middle of the nasal cavity and it forms 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 .
In the growth period, the nasal septum acts as a growth plate that affects surrounding bones
and facial skeletal tissues .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 .
Nasal septum deviation is the most common anatomic variation in up to 80% of healthy adults .
From the initial growth stages, the maxillary bone and nasal structure have significant
anatomic connections because of their close embryologic development.
The severity of septal deviation also affects the ipsilateral lateral lamina of the
cribriform plate width and ipsilateral middle turbinate length . Nasal septal deviation may
affect nasal bone growth and facial morphology .Knowledge of nasal morphologic parameters
plays an important role in planning successful rhinoplasty and septoplasty operations.
Some morphological characteristics of the nose such as bone length and thickness may present
different forms according to factors correlated with age, gender, climate and race.
