Nasal alar deformity can be caused by congenital dysplasia, trauma and infection. The main manifestations are alar base deviation, alar hypertrophy, alar contraction and alar cartilage dysplasia.
Nasal alar deviation is mostly unilateral, which can be basically divided into four forms: downward deviation, lateral deviation, medial deviation and upward deviation. Generally, Z-shaped shaping technology can be used to correct it. Severe deviation can also be transplanted with adjacent rotating flap, or auricle and contralateral alar tissue flap.
Extended data
The nose is the initial part of the respiratory tract and also the olfactory organ. It consists of external nose, nasal cavity and paranasal sinuses, and consists of nasal bone, nasal cartilage, nasal muscle and covered skin.
The nasal cavity is divided into left and right cavities by the nasal septum, with the nostrils communicating with the outside world at the front and the nasopharynx at the back. In front of the nasal cavity is the nasal vestibule, which is covered with skin and has nasal hair, which plays a filtering role and is prone to boils. The posterior part is the proper nasal cavity, lined with mucosa, which can be divided into olfactory part and respiratory part. Has the functions of smelling fragrance, moistening and purifying inhaled air.
Sinus is located in the skull around the nasal cavity, which is a cavity containing gas and communicating with the nasal cavity, and its mucosa is connected with the nasal mucosa. When the nasal cavity is inflamed, it can spread to the sinuses and cause sinusitis. The paranasal sinuses are involved in moistening and heating the inhaled air, and play a role in pronunciation.
