Chronic rhinitis is a form of atrophy of the mucous membrane and glands of the nose. Chronic form of dryness of the mucous membranes. Chronic rhinitis associated with polyps in the nasal cavity.

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,
