Accidental Displacement of Mandibular Third Molar to Parapharyngeal Space: A Case Report

doi:10.13701/j.cnki.kqyxyj.2025.07.013

Abstract

Abstract: Iatrogenic mandibular third molar displacement is a rare but recognized intraoperative complication, where the displaced tooth or root may cause symptoms such as foreign body reactions, infections, pain, limited mouth opening, and dysphagia. This article reports a case of accidental displacement of a mandibular third molar to the pharyngeal space. Through literature review, the paper introduces how to avoid tooth and root displacement during the extraction of the third molar, as well as the corresponding treatment measures after displacement.

Key words: mandibular third molar, exodontia, foreign body, pharyngeal space
