What happens if the inferior alveolar nerve is damaged?
There is a range of common inferior alveolar nerve damage symptoms, regardless of how the IAN is damaged. A damaged IAN will reveal itself through pain or abnormal sensations in the chin, lower teeth, lower jaw, and lower lips. Nerve damage may result in speech difficulties and/or affect chewing.
How can inferior alveolar artery bleeding be prevented?
Bleeding, which is refractory to packing and local pressure, can be controlled by completing the osteotomy, isolating the vessel away from the inferior alveolar nerve (IAN), and ligating it with hemoclips. Use of electrocautery is avoided due to its proximity to the IAN.
Is inferior alveolar nerve damage permanent?
Clinical implications: Permanent nerve damage can very occasionally occur as a result of an inferior alveolar nerve block. The exact mechanism is unknown, and there is no means of prevention. Knowledge of the risks and complications of local anesthesia is essential.
What causes inferior alveolar nerve damage?
Introduction. Causes of inferior alveolar nerve (IAN) injury include local anesthetic injections, third molar surgery (TMS), implants, endodontics, ablative surgery, trauma, and orthognathic surgery.
How do you control inferior alveolar nerve damage?
The complete resolution of the paraesthesia and the control of pain achieved in the present case, suggests that a non-surgical approach combining prednisone and pregabalin is a good option in the management of inferior alveolar nerve damage subsequent to endodontic sealer extrusion.
Where is inferior alveolar artery from?
The inferior alveolar artery is the major blood supply to the mandible and mandibular teeth. This artery has a very consistent path, originating from the maxillary artery and passing inferiorly until it enters the mandibular foramen, accompanied by the inferior alveolar nerve and vein.
How is inferior alveolar nerve injury diagnosed?
Numbness usually will be felt on the side of implant placement, including the lower lip and chin. Another symptom that may indicate nerve damage is the feeling of tingling, tickling, or burning skin in other words, paraesthesia. In some cases, numbness may not appear immediately but later on.
How do you treat inferior alveolar nerve damage?
Treatment of inferior alveolar nerve damage often depends on the cause. It can include conservative treatment, or, if that’s unsuccessful, surgery. If the damage is due to a dental implant, the implant may be removed or replaced by a smaller implant.
