Suprahyoid neck fascial configuration,especially in the posterior compartment of the parapharyngeal space: A histological study using late‐stage human fetuses

The fascial configuration in the suprahyoid parapharyngeal space was evaluated using semiserial sagittal sections of 15 late‐stage human fetal heads. The prevertebral fascia covered the longus colli, longus capitis, and rectus capitis lateralis muscles, but was most evident along the longus colli muscle. The carotid sheath and its extension were located around the internal and external carotid arteries and the lower cranial nerves. The superior cervical ganglion was also inside the sheath. Even near full term, the fetal suprahyoid neck was short, with the jugular foramen and hypoglossal canal located at the posterolateral side of the oropharynx. Thus, the glossopharyngeal and accessory nerves ran across the upper part of the carotid sheath. Fasciae of the stylopharyngeus, styloglossus, and stylohyoideus muscles were attached to and joined the anterosuperior aspect of the carotid sheath. All these neurovascular and muscle sheaths are communicated with the visceral fascia covering the pharynx at multiple sites, and, together, they formed a mesentery‐like bundle. This communication bundle was made narrow by the anteriorly protruding longus capitis muscle. The mesentery‐like bundle was covered by the posterior marginal fascia of the prestyloid compartment of the parapharyngeal space. The external carotid artery ran on the lateral and posterior sides of the posterior marginal fascia. Consequently, the typical carotid sheath configuration was modified by muscle sheaths from the styloid process, communicated with the visceral fascia and, anteriorly, constituted the posterior margin of the prestyloid space.

The versatile use of temporoparietal fascial flap

Background: The pedicled or free temporoparietal fascial has been used in many areas, especially in head and neck reconstruction. This thin, pliable, highly vascularized flap may be also transferred as a carrier of subjacent bone or overlying skin.Objective: The aim of this study is to report our experience in versatile use of temporoparietal fascial flap (TPFF) and discuss the surgical anatomy and technique.Patients and Methods: A total number of 57 TPFFs have been used in periorbital, mid-facial, auricular, and tracheal reconstruction due to tumor resection, trauma, and congenital ear deformities.Results: All the flaps were successfully transferred without any major complication. The cosmetic results were quite satisfactory to all patients.Conclusion: The advantages and minimal donor site morbidity of TPPF makes this flap a good choice in many reconstructive procedures.

Plastination and computerized 3D reconstruction of the temporal bone

The purpose of this study was to generate a computerized 3D reconstruction of the temporal bone and intratemporal structures. A plastination technique was used to obtain equidistant serial thin sections of 1.2 mm thickness and, on an SGI workstation, a Contour-Marching Cubes algorithm was selected to reconstruct the temporal bone and intratemporal structures in three dimensions. All reconstructed structures can be represented individually or jointly and rotated in any plane. Any diameter and angle of a structure can be conveniently measured. The capability of reconstructing individual and combined images of intratemporal structures, viewing them from all surgical angles, and accurately measuring their spatial relationships gives skull base and otologic surgeons important guidance. The reconstructed model can also be used for resident education, rehearsal of an unfamiliar surgery, and for developing a new surgical approach.     

Fetal anatomy of the lower cervical and upper thoracic fasciae with special reference to the prevertebral fascial structures including the suprapleural membrane

The aim of this study was to find basic rules governing the fetal anatomy of the deep cervical fasciae and their connections to the mediastinal fasciae. We examined the histology of paraffin-embedded preparations of 18 mid-term fetuses (5 between 9 and 12 weeks of gestation, 3 between 15 and 18 weeks, and 10 between 20 and 25 weeks). The prevertebral lamina of the deep cervical fasciae (PLDCF) developed as an intermediate aponeurosis for the bilateral bellies of the longus colli muscles. In contrast, the alar fascia developed as a connecting band between the bilateral adventitiae of the common carotid artery. The retropharyngeal fascia became evident much later than the latter two fasciae. The fascia covering the thymus was thicker than the fascia for the strap muscles (the pretracheal lamina of the cervical fascia). The primitive suprapleural membrane, or Sibson's fascia, contained veins and fatty tissues, and was composed of the alar fascia rather than the PLDCF, tranversalis fascia, or endothoracic fascia. The prevertebral two-laminar configuration was rather evident in the early stages of development because, in the later stages, the fasciae together provided a multilaminar structure, especially in the lateral area in front of the longus colli, which suspended the cupula pleurae. To consider a continuation from the base of the neck to the upper mediastinum, the alar fascia seems to be a key structure for connecting the vascular sheath to the parietal pleura.     

激光扫描多平面动态测量下颈椎椎间高度退变后椎间孔的变化

目的　激光扫描三维重建后动态测量下颈椎椎间高度退变时相应节段椎间孔的变化,为临床诊治神经根型颈椎病提供新的思路和参考。 方法 选用6具新鲜成人尸体颈椎标本,以C5/6单节段脊柱功能单位（FSU）作为研究对象。椎间盘切除后将C5/6椎间高度置于基准高度状态,激光扫描仪扫描收集该状态下C5/6 FSU的空间关系信息,再对骨性单椎体进行全面扫描,在Geomagic Studio8.0软件中再现　C5/6基准状态,并模拟6种椎间高度退变模型,即C5椎向C6椎椎体面趋于平行移动基准高度的10%、　20%、30%、40%、50%和60%。多平面动态测量方法（MPDM）分别测量椎间孔容积、中间面积、内口以及外口面积。 结果 测量数据显示随着椎间高度持续的下降,椎间孔的容积和面积逐渐减小,当椎间高度丢失基准高度30%时,椎间孔中间面积首先开始与基准状态有显著性差异（P=0.003）。 结论 激光扫描三维重建原貌再现骨性表面,是获得精确测量数据的前提;动态测量的方法较为客观准确,是测量椎间孔的理想方法;测量发现在下颈椎骨性椎间孔随着椎间高度在下降而缩小,其中间面积首先发生显著缩小,提示此处容易发生狭窄而引起临床症状。
