Parestesia del nervio lingual post-exodoncia del tercer molar inferior incluido. Reporte de un caso

Abstract

The impacted lower third molar extraction can cause transitory injuries of the lingual nerve (between 2 % and 10 %) or permanent (below 0, 5 %). The aim is to present a case of lingual paresthesia, post-exodontia of the impacted lower third molar. We report 22-year-old female patient, who attended to the Development Mouth (bucal) Surgery Course from the Faculty of Dentistry of the ULA, with exodontia indication of the impacted lower third molar. After the clinical and radiographic evaluation, infiltrating and troncular jaw anaesthesia was applied. The modified Winter design and raising was performed with later 48 and primary closing extraction. The post-operatory control of suture removal was achieved after 7 days. The patient referred crawling sensation in the third and lateral edge of the right side of the tongue. A lingual paresthesia was diagnosed by the pinprick test. Weekly controls took place during 30 days. In conclusion, the modified flap design, the anaesthesia technique, the surgical time, the professional experience and the untimely maneuvers during the procedure are predisposing factors of post-surgical neuropathy. The recovery observed after four weeks confirmed the transitory affection of the lingual nerve.
