累及咽鼓管及颈内动脉（ICA）鼓室部分的中耳疾病，常使保守性的手术切除感到为难。迄今为止，为了处理中耳腔波及咽鼓管和ICA等周围组织器官的病变都需要将外耳道向下扩大。否则，ICA的暴露将受到限制，并将最终影响病变清除和功能恢复。该文介绍的向鼓室了方扩大的面隐窝进路 Middle ear diseases involving the eustachian tube and the tympanic compartment of the internal carotid artery (ICA) often make conservative surgical resection difficult. To date, the ear canal needs to be enlarged downward to treat the middle ear cavity and the lesions of the surrounding tissues and organs such as the eustachian tube and the ICA. Otherwise, ICA exposure will be limited and will ultimately affect lesion clearance and functional recovery.
