概括
皮手术改善了骨指数 (CI) 在三角形骨缩症患者,而后侧重建 (PVR) 正常化了内体积. 两者都没有完全纠正CI,这表明这些手术技术的结果不同.
科学领域:
- 面外科手术 面外科手术
- 儿科神经外科 儿科神经外科
- 医学成像分析分析 医学成像分析
背景情况:
- 刺骨骨同位症是一种导致头骨线过早融合的疾病,需要进行手术以使内体积和形状正常化.
- 皮手术和后面重建 (PVR) 是用于治疗斜骨骨关节缩症的手术技术,每种手术都采用不同的方法来实现扩张.
研究的目的:
- 为了比较Pi手术和PVR之间的体积和头骨形状结果,用于治疗沙吉塔头骨缩症.
- 为了评估每次手术技术后指数 (CI) 和内体积的变化.
主要方法:
- 进行了对18名患有非综合征性沙吉塔骨突症的患者3DCT扫描的回顾性分析.
- 患者被分为两组:接受Pi手术的患者和PVR患者,如果同时进行双额外轨道推进重建 (BFOAR),PVR患者进一步分层.
- 指数 (CI) 和内体积在术前和术后被测量,并与年龄和性别匹配的对照人群进行比较.
主要成果:
- Pi程序显著增加了平均CI,尽管它仍然低于对照组. 皮患者的术后内体积明显大于对照组.
- 后部重建 (PVR) 并没有显著改变CI,该CI在术后仍然低于对照组. 对于PVR患者,包括那些与BFOAR一起接受PVR的患者,他们的内体积正常化至控制水平.
- 与对照组相比,手术前的内体积在两个手术组都增加了. 区域体积分析表明,在两种手术之间,扩张的模式不同.
结论:
- 无论是Pi手术还是PVR都未能在患有沙吉塔骨同位症的患者中完全纠正头骨指数.
- 通过减少最初升高的体积,PVR使内体积正常化,而Pi手术显著增加了内体积.
- 每个手术所导致的独特的术后头骨形态需要进一步研究它们的长期功能和美学影响.

01:22Sutures of the Skull
10.1K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:14Cranial Bones: Superior and Posterior View
4.9K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial Bones: Lateral View
4.4K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
