Methods: Three-dimensional finite element was adopted to compare stress and displacement on osteotome-bone interface at the different shapes of top osteotomes top at osteotome sinus floor elevation.

Summers提出的&骨挤压上颌窦提升术&(osteo-tome sinus floor elevation，OSFE)，由于手术创伤小，术后反应轻，患者易于接受，已逐渐地被临床应用于上颌后牙缺失的种植体植入术中[1~5]。

The destruction of ditus ad antrum and ossicles is the due to the diagnosis of cholesteatoma. The development of the two side mastoid can be imcompatible.

CT发现听小骨和鼓窦人口破坏多提示胆脂瘤；双侧乳突发育可不一致。

Results:The lesion of cholesteatoma (8/17) appeared as mass shadows in tympanic sinusand and cavity with low denisty ring around, accompanied with obvious ossicles chain destruction.

结果：胆脂瘤8例表现为中耳腔内团块状影，周围低密度环包绕，听骨明显破坏及中耳窦腔扩大，骨缘硬化。4例肉芽肿多呈片状、条索状或网状，听骨破坏较轻。

The lateral wall of cavernous sinus or obital fascia where the tumor rotruded from was incised,and the tumor was removed piece by piece.

Transsphenoidal microsurgical removal of pituitary ACTH adenoma is the first choice in prevention and treatment of Nelsons syndrome. Follow-up examinations should be repeated at intervals.

经蝶窦垂体ACTH腺瘤切除是预防和治疗Nelson综合征的首选方法，术后应定期随访。

Results The incidence of Nelsons syndrome was 7.7%in series of 300 patients with Cushings disease treated by surgery in the same period. Hyperpigmentation was relived in all cases and ACTH level decreased. 8 cases with visual disturbance improved after surgery. Curative ratio was 56.5%, remission ratio was 26.1%.

结果 本组23例Nelson综合征，占同期手术治疗的库欣病的7.7%，经蝶窦手术后皮肤色素沉着减轻，血ACTH水平下降，8例视力视野障碍术后均改善，治愈率56.5%，缓解率26.1%。

Observation from the excavation, the tomb of Liu Sheng's corridor, South ears Room, North ear rooms and in the rooms, as well as the tomb of sinus bind room, originally built in the cavern where the roof is also a wooden structure, housing, the latter due to timber Xiu Fu and collapse.

Objective: To investigate the application value of MR brain surface anatomy scanning in the parasagittal meningiomas operations.

目的： 探讨磁共振脑表面成像技术在矢状窦旁脑膜瘤手术中的应用价值。

The relationship between parasagittal meningiomas and draining veins of brain surface can be identified by MR brain surface anatomy scanning, which can evaluate the draining veins correctly and direct to protect the key draining vein, especially the draining vein in functional area of brain surface. It plays important role in the protection of neurological function and the recovery of the postoperation.

磁共振脑表面成像技术能在术前明确矢状窦旁脑膜瘤与脑表面回流静脉之间关系，可在术前对患者肿瘤表面脑回流静脉做出正确的评估，对脑表面重要回流静脉的保护提供了准确的影像学依据，对患者神经功能的保护及术后恢复起到重要作用。
