Third Molar Extraction
Inferior alveolar and lingual nerve injuries can cause:
Patients with paresthesia in the distribution of the IAN(inferior alveolar nerve).
Patients with complete anesthesia post-operatively.
Mild paresthesia or permanent loss of sensation may occur in case of IAN injuries during third molar removal.
Distoangular impactions poses a high risk of lingual nerve injury because of the close proximity of the lingual nerve fibers and lingual plate distal to mandibular third molar. Complete recovery usually occurs after several weeks to months. However, in case of permanent loss of taste sensation, surgery is essential to promote recovery of the lingual nerve.
The abnormal sensations fade with time.
Some diminish in days or weeks.
Others see a decline within months.
Nerve injury during third molar removal is rare, and non-recovery is extremely rarer.
