Introduction
Without an eardrum, one cannot hear sounds properly, and the ability to hear is generally directly related to the nervous system. Patients without an eardrum are advised to undergo surgical treatment, such as eardrum repair, depending on their condition. After surgery, it is important to keep the ear dry and clean, preventing water from entering the ear. When washing hair or showering, sterile cotton balls can be used to block the ear canal, and patients should avoid dusty environments.
It is possible to hear sounds even without an eardrum, as hearing generally has a direct connection with the nervous system.
The eardrum is an elastic, grayish-white, semi-transparent membrane that separates the external auditory canal from the middle ear. Under normal conditions, the eardrum detects sound waves entering through the external auditory canal, vibrates in response, and transmits these vibrations via the attached ossicular chain into the middle ear. Within the entire auditory conduction pathway, the eardrum serves as one of the initial stations. Even without an eardrum, sound can still be perceived, although it will be quieter. Moreover, hearing involves both bone conduction and air conduction, so individuals without an eardrum can still hear sounds. Patients who lack an eardrum or have a perforated eardrum can undergo surgical treatment. The procedure is performed under anesthesia and carries relatively low risk.
It is recommended that patients without an eardrum consider undergoing eardrum repair surgery based on their individual condition. After surgery, they should keep the ear dry and clean, prevent water from entering the ear, use sterile cotton balls to block the ear canal during hair washing or showering, and avoid dusty environments.
