mastoid bone

Methods On 60 sides adult temporal bone specimens, the related anatomic structures were well exposed by opening the mastoid cavity and removing the lateral wall of external auditory canal and tympanic scutum.

方法利用成人60侧颞骨标本，用牙科钻磨开乳突腔，打开外耳道外侧壁和鼓室盾板，充分暴露后鼓室入路手术中有关的解剖结构。

After stripping partial mastoid process, a 3.5cm × 3cm bone window at the temporal part was made to expose the anterior part of the sigmoid sinus and temporal dura mater. Many anatomic structures can be observed under microscope when cerebellar hemisphere and temporal lobe were drawn away.

磨除部分乳突后联合颞部开颅，形成一3.5cm×3cm大小的骨窗，暴露并剪开乙状窦前和颞部硬脑膜，牵开颞叶和小脑半球，显微镜下观察所显露的解剖结构。

B. Palpate auricle for texture, tenderness, and presence of lesions. If client complains of pain, gently pull auricle and press on tragus and behind ear over mastoid bone.

触碰耳廓检查质地、触痛，有无损伤。如受检者叫痛，轻拉耳廓和按耳屏及耳后颞骨乳突部。

In the operation, temporal fascia was used to repair the drum and self cortex of mastoid bone or artificial porcelain auditory ossicles were used to reconstruct the ossicular chain.

采用颞肌筋膜修补鼓膜，以自体乳突骨皮质或陶瓷人工听骨重建听骨链。

Rebuild scute with auto-bone or infill the mastoid cavity with auto bone pieces;
