Nasal hair Nasal hair Nasal hair or nose hair is the hair in the nose. Adult humans have hair in the interior nasal passage. Nasal hair functions include filtering foreign particles from entering the nasal cavity and collecting moisture. In support of the first function, the results of a 2010 study indicated that increased nasal hair density decreases development of asthma in those who have seasonal rhinitis, possibly due to an increased capacity of the faces to filter out pollen and other allergens. Nasal hair should not be confused with cilia of the nasal cavity, which are the microscopic cellular strands that,
Nasal reconstruction using a paramedian forehead flap forehead flap is usually required if the nasal defect is larger than 1.5 cm, requires replacement of support or lining, or if it is located within the infratip or columella. If the defect is small and superficial it can be resurfaced with a skin graf or it can heal by secondary intention. Limited alar defects can be resurfaced using a nasolabial flap, however, the amount of tissue available from the nasolabial area is limited and the flap is thicker, less vascular, and hair bearing in males. Nasal defects mostly result from excision of (malignant) skin tumours as basal cell carcinoma,
