Mandibular Paresthesia Case Studies

To expound upon the concern listed above, IAN nerve damage, mandibular paresthesia or dysesthesia may result which may or may not resolve on its own. Additionally, the lingual nerve may be damaged causing complete or partial paresthesia of the tongue. The position of the third molars appears to play a role in the incidence of IAN injury; teeth that are impacted and horizontally positioned have a higher frequency of IAN injury. Regarding the lingual nerve, although permanent sensory deficits are rarely reported, up to 20% of patients report some level of post-op sensory impairment.20 In a 2010 case study reported by Ruga et al, following unsuccessful attempts made by a general dentist to extract mandibular third molars, the patient experienced referred hypesthesia of her right …show more content…
The OS team to whom the patient was referred decided to extract the remaining roots. Osteotomy was also done with irrigation to prevent hard tissue necrosis. Roots had previously been luxated, and were separated at this visit to “preserve [the] alveolar bundle integrity in case of root perforation.” The retained third molar roots were then removed individually. The socket was irrigated. The IAN bundle had been exposed during the surgical procedure, and while it did not appear to be completely section, it was “diffusely lacerated”. The OS doctors rinsed the socket with clindamycin solution to prevent bacterial infiltration and a fibrin sponge was placed to provide spongy (“noncompressive”) protection. Primary closure was performed.22 Post-op therapy was mainly provided to prevent edema and possible
