Transient mutism has been reported following commissurotomy and callosotomy. The cause for this mutism is unknown. A case of mutism following callosotomy is presented, and the preoperative and postoperative data on neurological, physiological, and psychological functioning are discussed. The data suggest that the mutism is not caused by general intellectual deterioration, cortical lesion, or peripheral damage affecting speech production. The syndrome may result from severing interhemispheric connections in cases where both hemispheres are required for speech production.
据报道，在进行连合部切开术和胼胝体切开术后会出现短暂性缄默症。这种缄默症的病因尚不清楚。本文介绍了一例胼胝体切开术后出现缄默症的病例，并讨论了术前和术后关于神经、生理和心理功能的数据。数据表明，缄默症并非由一般智力衰退、皮质病变或影响言语产生的外周损伤引起。该综合征可能是由于在言语产生需要双侧半球参与的情况下切断了半球间连接所致。
