The nasal septum is the tissue that divides the nasal cavity into left and right parts. It consists of bone, cartilage and mucous membrane. Lined with mucosa and skin. The nasal septum is divided into left and right cavities, the front cavity communicates with the outside world through the nostril, and the back cavity communicates with the throat through the back nostril. Each nasal cavity can be divided into nasal vestibule and inherent nasal cavity, with nasal flap as the boundary. Nasal vestibule refers to the enlarged space around the alar, with skin lining and nose hair on the inner surface, which has the function of retaining and absorbing dust.
The nasal septum of normal people is rarely completely in the middle, and most of them have a certain deviation, which is ridged or spiny to one or both sides, or irregularly convex to the nasal cavity. When the nasal septum is deviated, it is easy to have symptoms such as nasal congestion, headache and nosebleeds. There is a venous plexus in the anterior lower part of the nasal septum, which is the prone site of epistaxis.
The harm of nasal septum deviation;
1. Deviation of nasal septum can often lead to nasal congestion and epistaxis on one side, and can also cause symptoms such as head reflex pain. ?
2. When the nasal septum is seriously deviated, if it is not treated in time, it can also lead to inflammation spreading to the respiratory tract, upper respiratory tract infection and neighboring tissues and organs, which can lead to sinusitis, otitis media and tonsillitis. And dizziness, headache, sore throat and abnormal hearing. ?
3. Deviation of nasal septum blocked a nasal passage. Because the air intake of the other nasal cavity is not enough, there will be open mouth breathing. Slight deviation of nasal septum has little effect on the body and basically does not need treatment. If the deviation of nasal septum is serious and has caused obvious symptoms in patients, surgical treatment can be considered to correct the deviation of nasal septum.
