Dentigerous or follicular cysts of odontogenic origin are innocuous benign cysts that are often linked with the crowns of permanent teeth. A dentigerous cyst circumventing permanent teeth fails to erupt and is often displaced into ectopic positions in the upper and lower jaw in the maxillofacial region. In the maxilla or upper jaw region, the impacted teeth are often displaced and/or shift into the maxillary sinus and apart from the nasal septum, mandibular condyle, coronoid process and the palate, to harbour such ectopic eruptions of teeth. We report a rare case of an impacted left third molar of maxilla, associated with dentigerous cyst. The impacted tooth was embedded in the anterosuperior part of the infratemporal space. The cyst along with the tooth was removed using a modified Caldwell Luc incision.
牙源性含牙囊肿或滤泡囊肿是无害的良性囊肿,常与恒牙牙冠相连。围绕恒牙的含牙囊肿未能正常萌出,常移位至上颌骨和下颌骨的异位位置,位于颌面区域。在上颌骨或上颌区域,阻生牙常移位和/或移入上颌窦,除了鼻中隔、下颌髁突、冠状突和腭部外,还会出现这种牙齿的异位萌出。我们报告一例罕见的上颌左侧第三磨牙阻生伴含牙囊肿的病例。阻生牙嵌入颞下间隙的前上部。采用改良的柯-陆氏切口切除囊肿及牙齿。
