After a surgical or traumatic lesion to the trigeminal nerve, anesthesia dolorosa, a rare de-afferentation discomfort, may develop. Without any nociceptive stimulation, this results in spontaneous pain signals. Trigeminal neuralgia can result from compression of the trigeminal nerve caused by auditory neuromas or other structures close to the cerebellopontine angle (CPA), however anesthesia dolorosa following the removal of an acoustic tumor has not been documented in the medical literature. acoustic neuroma surgery with dolorosa anesthesia along the spread of the trigeminal nerve. Multidisciplinary approaches were used to address the patients pain with varying degrees of success.

Patients with anesthesia dolorosa, a chronic pain syndrome, report having numbness in certain facial regions along with ongoing, excruciating pain. This injury results from damage to the first order trigeminal nerve, which triggers the trigeminal pain pathway's second-order neurons to fire spontaneously, sending pain signals without any nociceptive stimuli. Some of the people who had trigeminal rhizotomy experience it. Despite being a well-documented side effect of trigeminal rhizotomy, anesthesia dolorosa is not frequently linked to auditory neuroma surgery. The development of the anesthesia dolorosa either after an auditory neuroma caused by tumor involvement or after surgical intervention is not supported by any medical literature.

In the medical literature, anesthesia dolorosa is referred to as the trigeminal nerve distribution that most frequently develops as a side effect of rhizotomy or thermocoagulation to treat trigeminal neuralgia. According to estimates, the prevalence of anesthesia dolorosa is 0–1.6% in instances following glycerol rhizotomy, 0.8–2% in cases following radiofrequency rhizotomy, and 3% in cases following percutaneous controlled thermocoagulation. Surgery and gabapentin are generally used to treat anesthesia dolorosa.

Following radiation therapy or surgery for an acoustic neuroma near the trigeminal nerve, anesthesia dolorosa may occur. Even with the use of complete multidisciplinary approaches and pain management treatments like nerve blocks and radiofrequency nerve ablation, it may be challenging to achieve adequate pain control. A localized pain is anesthesia dolorosa. Therefore, we might use deep brain stimulation devices to treat these patient groups in a manner similar to how we treat thalamic stroke. Future therapeutic options for these patients may include electrical neuromodulator of the brain's deep brain, periaqueductal grey, and thalamic regions.

Persistent neuropathic pain and numbness along the affected nerve damage's region are the hallmarks of anesthesia dolorosa. Mechanical, thermal, chemically generated, or radiation-related factors might result in the traumatic event and nerve injury, depending on the surgical technique used and the tumor's features, acoustic neuroma surgery might result in a number of problems. Systematically examined are the surgical outcomes of auditory neuromas with various surgical techniques. The three techniques that were examined were the middle cranial fossa approach, retro sigmoid approach, and trans labyrinthine route. The most frequent side effects are postoperative headache, facial nerve dysfunction, hearing loss, and cerebrospinal fluid leak.
