头骨的主要特征是：枕骨的颈交不发达，眶上突不与颧弓相连，无眶上孔；颞骨岩部形成半球形鼓泡，鼻骨与颌前骨的鼻突之间不形成鼻颌切迹；泪骨几乎无颜面部；颌前骨的鼻突发达；上颌骨外面无面嵴；腭骨发达；犁骨腹缘后部不与鼻腔底壁接触；下颌骨支下缘无血管切迹、垂直部后下方有一角突。

Methods Twenty-two pieces of temporal bone were taken for this study. The mastoid cavity was opened, scutum removed,"bridge" broken down, posterior wall of external auditory canal abraded and the related anatomic structures were fully exposed. The distance between the origin of facial nerve canal and the anterior border of round window （ OOFNC-ABORW ）, between the highest point of the facial nerve canal and the bottom of posterior mastoid sinus,and between the stapes head and round window niche was measured under operating microscope.

方法取成人颞骨22侧（左右各11侧），用耳科钻磨开乳突腔，去上鼓室盾板、断"桥"，磨低骨性外耳道后壁，充分暴露相关结构，在手术显微镜下测量面神经管垂直段起始部前缘至圆窗龛前缘的距离、面神经管最高点与后鼓室底壁之间的距离、锥隆起的高度（即锥隆起基底到锥隆起顶端的距离）、镫骨头至圆窗龛前缘的距离。

Temporal bone fracture occasionally occurs, but a pure fracture of tympanic portion of the temporal bone is less common.

styloid process：茎突

(五)茎突 茎突(styloid process)起于颞骨鼓部的下面,伸向前下方,呈细长形,长短不一,平均长约25mm;远端有茎突咽肌、茎突舌肌、茎突舌骨肌、茎突舌骨韧带和茎突下颌韧带附着.

scala tympani：鼓室阶

植入之方式是在全身麻醉下,於已剥除毛发的耳后作一皮肤切口,藉由乳突切开(mastoidectomy),由后方进入中耳腔(posterior tympanotomy),将电极经圆窗上方施行耳蜗造口术(cochleotomy)植入耳蜗之鼓室阶(scala tympani)内,接收器的部分则放置於颞骨上磨出之凹槽内,

internal ear：耳

内耳(internal ear)由于结构复杂,又称为迷路,全部埋藏于颞骨岩部骨质内,介于鼓室与内耳道底之间,由骨迷路和膜迷路构成. 骨迷路由致密骨质围成,是位于颞骨岩部内曲折而不规则的骨性隧道. 膜迷路是套在骨迷路内的一封闭的膜性囊.
