Fracture of the angle of the mandible accounts for nearly one-third of all fractures involved. The presence of lower third molar increases the risk of fracture in angle region. The third molar acts as an area of weakness leading to fracture lines passing medially, distally, and occasionally through it. Angle fracture leads to the mobility of the third molar and sometimes its displacement. Third molars maintain its position in favorable fracture and can be displaced in unfavorable fractures. Displacement of lower third molar in lateral pharyngeal space due to mandibular fracture is not seen commonly. To our knowledge, this is the first reported incidence of displacement of the third molar into lateral pharyngeal space in a case of mandibular fracture.
下颌角骨折约占所有下颌骨骨折的三分之一。下颌第三磨牙的存在增加了下颌角区域骨折的风险。第三磨牙作为一个薄弱区域，导致骨折线向内侧、远中延伸，偶尔穿过该牙。下颌角骨折会导致第三磨牙松动，有时还会移位。在有利的骨折情况下，第三磨牙保持其位置，而在不利的骨折中则可能移位。下颌骨骨折导致第三磨牙移位至咽旁间隙的情况并不常见。据我们所知，这是首次报道下颌骨骨折病例中第三磨牙移位至咽旁间隙的发生率。
