Deviated nasal septum is a common structural abnormality of the nasal cavity, most often causing symptoms such as nasal congestion, headaches and nosebleeds. Mucosal erosion on the surface of the nasal septum can be caused by a variety of factors, and its severity is closely related to the nature of the lesion. General inflammatory diseases such as dry rhinitis and atrophic rhinitis are less serious, while nasal lymphoma is often more serious.
1. dry rhinitis, atrophic rhinitis: the main pathological changes of this disease are epithelial degeneration, progressive atrophy, occlusive endarteritis and cavernous venous plexus inflammation of mucous membrane and bone vessels, connective tissue hyperplasia and hypertrophy of blood vessel wall, narrowing or occlusion of the lumen, poor blood supply leading to mucous membrane, glands, periosteum, and atrophy of the bone, fibrosis, and squamous epithelialization, which may appear as mucous membrane vesiculation.
2. Nasal lymphoma: the lesions mostly start from the nose, mainly located in the midline area of the face and the upper respiratory tract, with progressive granulomatous ulceration and necrosis as the main cause, which is destructive and can invade the bone and cartilage, resulting in disfigurement. The histopathologic features are diffuse lymphomatous infiltration, vascular centrality, and vascular destructive growth patterns leading to tissue ischemia and necrosis, as well as ulceration of the mucosal areas.
Mucosal erosion of deviated nasal septum can also be caused by other reasons, and should be promptly consulted in the hospital, systematically examined to clarify the diagnosis, and standardized treatment in accordance with the doctor’s instructions.
