Surgery can be done in order to help the nerve heal. The surgery will help with nerve regeneration, providing guidance to the nerve sprouts on where to attach on the proximal side of the injury. Damaged nerve axons can reattach themselves after surgery. [3] Treatment of axonotmesis also consists of: Physical therapy or Occupational Therapy ...
This reflects good practice recommended by the Royal College of Anaesthetists (prior warning of potential nerve injury in relation to spinal and epidural blocks 1 on 24–57,000 risk). [5] [failed verification] Infiltration dentistry is a technique that may reduce the possibility of lingual nerve injuries by avoiding deep injections. [6]
Nerve injuries occur in 3.7% of the patients after the mandibular setback surgery. [49] Cutting and repositioning of the mandible in the surgery can potentially damage nerves in the mandible that is responsible for sensation and movement. Specifically, the inferior alveolar nerve are the commonly affected nerve in the surgery. [50]
This type of nerve damage may cause paralysis of the motor, sensory, and autonomic functions, and is mainly seen in crush injury. [2] If the force creating the nerve damage is removed in a timely fashion, the axon may regenerate, leading to recovery. Electrically, the nerve shows rapid and complete degeneration, with loss of voluntary motor units.
Neurotmesis (in Greek tmesis signifies "to cut") is part of Seddon's classification scheme used to classify nerve damage. It is the most serious nerve injury in the scheme. In this type of injury, both the nerve and the nerve sheath are disrupted. While partial recovery may occur, complete recovery is impossible.
Denervation can occur as a consequence of nerve injury. The three primary categories of nerve injury are neurapraxia, axonotmesis, and neurotmesis, each corresponding to varying degrees of damage and potential for recovery. In cases of nerve injury, the brain demonstrates an impressive ability to rewire or reorganize its neuronal circuitry ...
Injury to the inferior alveolar nerve resulting in numbness or partial numbness of the lower lip and chin has reported rates that vary widely from 0.04% to 5%. [23] The largest study is from a survey of 535 oral and maxillofacial surgeons in California, where a rate of 1:2,500 was reported.
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
