When is item code 52803 (Interfascicular Nerve Trunk Neurolysis) typically used?

The need for interfascicular neurolysis of a nerve trunk using microsurgical techniques arises when a patient has a major nerve trunk in the oral and maxillofacial region—often the facial or trigeminal nerve—entrapped or scarred within its fascicles, causing severe pain, numbness, or paralysis, requiring precise surgical freeing under anesthesia with assistance in a hospital using microscopes. This is indicated for complex nerve damage, critical where nerve function affects maxillofacial sensation or movement.

Specific scenarios include:

  • Trauma: Facial nerve injury from a fracture needs micro-release.
  • Surgery: Post-operative scarring causes dysfunction.
  • Pain: Trigeminal entrapment prompts neurolysis.
  • Function: Restores facial movement or sensation.

For instance, a patient with facial paralysis post-trauma might need this to free the nerve, with micro-precision. In aged care, an elderly patient could benefit for sensation, given frailty. By meticulously releasing the nerve, this service restores function, relieves pain, and enhances quality of life, making it a specialized maxillofacial procedure.

Benefits to the patient

Surgeons performing interfascicular neurolysis on the patient’s nerve trunk using microsurgical techniques under anesthesia with assistance deliver precise benefits. A key advantage is restoring nerve function. This meticulous procedure frees the patient’s nerve fibers, enhancing conductivity—vital for 'microsurgical neurolysis benefits.' It also relieves severe pain by addressing deep compression, improving the patient’s comfort. Furthermore, it improves sensation or movement by optimizing nerve health, aiding the patient’s capabilities. For surgeons researching 'interfascicular neurolysis advantages,' this assisted service ensures patients benefit from functional restoration, pain relief, and sensory or motor enhancement, offering an advanced fix for nerve trunk issues.

Recovery considerations

Recovery of 3-4 weeks with swelling and nerve recovery; hospital stay required.
