概括
与状片相比,状片在下重建中是首选的,因为它具有优越的形态稳定性和骨维度保护. 这两种技术都提供了相似的整体生活质量,但阴茎片提供了更好的临床结果.
科学领域:
- 口腔和牙面部外科手术
- 重建性手术是一种重建性手术.
- 生物材料科学 生物材料科学
背景情况:
- 部缺陷通常需要重建以恢复形状和功能.
- 阴茎和骨是下重建的常见选择,每一个都有不同的特点.
- 将它们的长期形态和功能结果进行比较对于手术决策至关重要.
研究的目的:
- 为了比较 mandibular重建的形态和功能结果,使用 iliac 和 fibular 片.
- 从患者的结果来看,评估每个片技术的有效性.
- 确定下重建的最佳手术方法.
主要方法:
- 追溯分析121名患者 (84名阴道,37名状).
- 使用Mimics软件对手术前后扫描进行形态分析,以评估参数和对称性.
- 使用华盛顿大学生活质量调查问卷 (UW-QOL) 评估生活质量.
主要成果:
- 在未受影响的侧面,阴茎在特定距离 (D2,D3) 和角度 (CA) 上表现明显更好.
- 叶片在距离D3时表现出优越的对称性,在角度B时表现出更好的稳定性.
- 叶片更好地保存了气囊底高度 (ABH) 和宽度 (ABW).
- 整体而言,生活质量没有差异,但在疼痛/活动方面,骨的得分更高,而在外表/言语方面,骨的得分更高.
结论:
- 叶片是下重建的首选选择,因为它具有卓越的形态稳定性和骨维度保存.
- 虽然整体生活质量是可比的,但下腹膜提供了更明显的临床益处和强大的结构一致性.
- 这两种技术都有特定的优势,但阴茎带来了更优的术后结果.

Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
