Cholesteatoma, also called epidermoid cyst, is a congenital benign tumor of ectopic embryonic remnant origin that grows slowly. Cholesteatomas located in specific areas of the posterior cranial fossa often start as trigeminal neuralgia (70%), and in addition patients often feel tinnitus, deafness, or facial numbness and discomfort. Because cholesteatoma is a benign tumor and grows slowly, patients should not be too alarmed. Early surgical removal will also give good results. Trigeminal neuralgia is a paroxysmal, severe pain on one side of the face that is pins and needles, cuts, electric shocks, tears or fire burns. The pain usually lasts from a few seconds to a few minutes, with sudden onset and off, and intermittent periods may be asymptomatic. Pain can be caused by talking, eating, brushing teeth, washing face, shaving, yawning, etc. The disease may have remission, but there is very little chance of self-healing. Trigeminal neuralgia is most likely to be misdiagnosed as toothache. The disease can be treated with carbamazepine to provide temporary pain relief, but it does not eliminate the root cause. Local closure and radiofrequency are also effective, but are associated with side effects such as facial numbness, and often recur within a short period of time. Surgery, on the other hand, is more thorough. All patients diagnosed with trigeminal neuralgia require an MRI to rule out tumors. Of course, the diagnosis and treatment of this disease is best performed by an experienced physician in a regular hospital.
