The main symptoms of patients with chronic suppurative otitis media are pus in the ear and gradual hearing loss, with the tympanic membrane showing perforation. Antimicrobial medication for these patients can only serve the purpose of symptom control. In the hope of completely removing the inflammation and repairing the eardrum, they need to undergo otologic surgery. Chronic suppurative otitis media is divided into two cases: the first case is the non-risk type of chronic suppurative otitis media. These patients exhibit intermittent pus flow from the ear, or have a longer period of time without pus flow from the ear. Ear hearing gradually decreases, or there is a longer period of time when hearing remains the same. Medical examination reveals perforation of the eardrum and conductive hearing loss. Patients in this category may receive surgical treatment to repair the eardrum (tympanic membrane repair) and prevent infection. Due to the presence of a perforated tympanic membrane, the outer ear canal is not allowed to enter water. Bathing or swimming can cause water to enter the ear and lead to infection. Repeated infections can lead to gradual hearing loss. Tympanic membrane repair is a procedure that improves the quality of life. The non-risky type of chronic suppurative otitis media does not usually lead to intracranial or extracranial complications of otitis media. Another condition that is a risk type of chronic suppurative otitis media is what we commonly refer to as middle ear cholesteatoma or chronic suppurative otitis media with bone ulcers. This type of otitis media can cause facial paralysis, severe hearing loss or even total deafness and vertigo due to the presence of damage to the surrounding bone. Intracranial invasion and destruction can lead to intracranial complications: meningitis or brain abscess, which can be life-threatening in severe cases. The risky type of chronic suppurative otitis media needs to undergo surgery to remove the cholesteatoma and prevent complications and other dangers. Early surgery can preserve more hearing function and the scope of surgical trauma is small. You may have chronic suppurative otitis media if you are experiencing ear discharge and hearing loss, and you need to seek medical attention as soon as possible. Whether your chronic suppurative otitis media is dangerous or non-dangerous will need to be determined by an experienced physician. Surgery for chronic suppurative otitis media requires a high level of skill, and in terms of the current medical situation in China, this type of surgery can only be performed in the otology departments of some large tertiary care hospitals.
