Pneumatocele of the infratemporal fossa caused by herniation of air through a break in the wall of the aerated maxillary sinus is rare. Two cases are reported: one arising from a maxillary pneumocele with a defect in the wall of the zygomatic recess and one associated with maxillary radionecrosis with pathological fracture complicated by infection. Computed tomography can clearly demonstrate the extent of the pneumatocele, and can show the maxillary pathology and the causative bony defect in the sinus. Treatment depends on the clinical conditions of the patient, the pathology and the size of the bony defect.
因气体通过含气上颌窦壁破裂处疝出导致的颞下窝气囊肿罕见。本文报告两例：一例源于颧骨隐窝壁有缺损的上颌气囊肿，另一例与上颌放射性骨坏死伴病理性骨折并感染有关。计算机断层扫描能清晰显示气囊肿的范围，并可显示上颌病变及窦内的病因性骨质缺损。治疗取决于患者的临床状况、病理及骨质缺损的大小。
