Eardrum repair surgery refers to tympanoplasty, a surgical procedure that can be performed to repair perforations, restore the integrity of the eardrum, and improve hearing through tissue grafting techniques. Its main functions and benefits include: blocking the occurrence of foreign bodies and infections in the middle ear through the external auditory canal, treating conductive hearing loss caused by tympanic membrane perforation, and re-establishing the normal ventilation and drainage mechanism of the middle ear.
1. Blocking the occurrence of foreign bodies and infections in the middle ear through the external auditory canal: The tympanic membrane is a natural barrier separating the outer ear from the middle ear. When there is a perforation of the tympanic membrane, pathogenic factors such as foreign bodies, sewage, and pathogenic bacteria can enter the middle ear cavity from the external auditory canal, triggering or exacerbating the occurrence of middle ear diseases such as septic middle ear. This pathologic structural abnormality can be repaired by choosing tympanoplasty.
2. Treatment of conductive hearing loss caused by tympanic membrane perforation: the tympanic membrane is an important link in the auditory conduction pathway. When part of the tympanic membrane is perforated, the sound waves cannot be adequately transmitted through the amplification of tympanic membrane vibration to the next link, resulting in conductive hearing loss. Surgical repair of the tympanic membrane can compensate for this structural defect.
3. Reconstruction of the normal ventilation and drainage mechanism of the middle ear: the ventilation and drainage in the middle ear need to be realized by the negative pressure suction generated by the tympanic membrane activity when the Eustachian tube is open and closed, when the eardrum is perforated, this effect disappears, which will easily lead to inflammatory reaction in the middle ear. Eardrum repair surgery can rebuild this structural defect and restore the normal function of the middle ear.
Before choosing eardrum repair surgery, systematic examination should be conducted to clarify whether it meets the indications, whether there are absolute contraindications, and standardize the treatment in accordance with the doctor’s instructions.
