White membrane inside the ear can be considered to be related to conditions such as tympanosclerosis, fungal disease of the external auditory canal or cholesteatoma of the external auditory canal. 1. Tympanosclerosis: Its occurrence can be related to heredity, otitis media or tympanotomy and replacement, etc. Under otoscopic examination, white patches of the tympanic membrane are commonly seen, resembling white membrane-like changes, which can be accompanied by hearing loss, tinnitus and other symptoms. 2. Fungal disease of the external auditory canal: fungal infectious disease can occur in the external auditory canal under the condition of water ingress, accumulation of secretion, etc. As the fungus grows and multiplies in the external auditory canal, white powdery or fluffy fungus can be formed, and there is a scab that looks like a film appearing. 3. Cholesteatoma of the external auditory canal: it may occur after the skin of the external auditory canal has been stimulated by inflammation, foreign body and fungal infection for a long time, and the examination shows that there is a white or yellow cholesteatoma-like material blocking the deep part of the external auditory canal, and the surface is wrapped with multi-layer scaly material. If you find any abnormalities inside the ear, you should seek medical advice in time to clarify the cause of the disease, and then treat the cause and symptoms.
