重型颅脑损伤与假性关节强直

Severe head injury and pseudoankylosis of temporomandibular joint

重型颅脑损伤常表现为颅内血肿、高压,通常需要立刻行开颅手术,降低颅内高压以保护脑部组织。翼点开颅是神经外科经典手术入路之一,能充分暴露前、中颅底以及鞍区,但由于需要剥离和牵拉颞肌,常常导致术后颞肌纤维化甚至萎缩,产生张口受限。下面就重型颅脑损伤术后所导致的颞下颌关节假性关节强直作一综述。

Intracranial hematoma and intraeranial hypertension are common after severe head injury. Then craniotomy is needed to perform in time. Among the operational approaches, pterional craniotomy for its advantage to expose the skull base and saddle area is usually selected, however, inappropriate dissection of the temporal muscle often induce postoperationive muscle atrophy, and mouth opening limited. This article reviews the postoperationive pseudoankylosis after severe head injury.
