Blackheads in the inner ear may be related to excessive sebaceous gland secretion and lack of attention to cleanliness. 1. Excessive sebaceous gland secretion: If the sebaceous gland secretion in the inner ear is relatively strong, it may lead to blockage of the hair follicle exit area, and the sebaceous gland will be blocked in the area, and after a long period of time, the sebaceous gland will be oxidized and turn into black color, that is, the so-called blackheads, and after squeezing, there will be long strips of sebaceous glands appearing, and there will be a black spot on the top. 2. Do not pay attention to clean: Because the inner ear nest is close to the inner part of the ear, if the patient does not regularly wash the part thoroughly, it will lead to oil, dander, dirt and other impurities in the deposition of this collection, if the hair follicles will be blocked, it will gradually form blackheads. Blackheads in the inner fossa of the ear are also prone to localized infections, which should be promptly consulted and actively treated or dealt with.
