Surgical Tip of the Week #9How To Avoid IAN Injury - Deflection of Root
A quality panoramic x-ray is sufficient when assessing possible IAN injury while removing third molars. Nine panoramic radiographic markers can reliably predict IAN injury. ACT is recommended when injury is likely.
DEFLECTION OF ROOT
The final radiographic sign for possible IAN contact is root deflection. It should be emphasized that none of the STOW radiographic signs are absolute indicators of IAN contact. Furthermore, contact of third molar roots with the IAN canal and nerve does not always result in paresthesia. These radiographic signs are red flags indicating caution should be observed. A referral to a maxillofacial surgeon or CT scan should be considered. Conversely, superimposition is not a guarantee that nerve injury will not occur. Patient age is always a consideration.
