The cardiac fibrous skeletal ring model: Simple,inexpensive method to illustrate normal and abnormal cardiac anatomy three dimensionally

A novel, innovative, simple, and inexpensive graphic method is proposed to facilitate illustrating the variety of cardiovascular pathology. Six-ring plastic container holders, resected selectively, or circles carefully drawn to represent the cardiac fibrous skeleton, enable visualization of the cardiac pathology three-dimensionally without notations. Given 9 axioms, this systematic technique is easy to learn and teach, enabling a nonartistic neophyte to understand complex, cardiac anatomic perspectives and diagram specific cardiac anomalies.     

200例国人眼眶外侧沟及相关结构的观察

本文观察了200例成人骨眶,发现有眶外侧沟77例(38.5±3.4％),此沟提示脑膜中动脉的眶支与眶下动脉的吻合所在。脑膜眶孔的出现率为33.0±3.3％,此孔的局部位置在眶上裂外侧端外侧的邻近部位。脑膜中动脉的眶支沟的出现率为82.0±3.8％,此沟延至眶上裂或脑膜眶孔。     

The radicular palatal groove – a therapeutic modality

Abstract A radicular palatal groove may be present in about 8.5% of the population, mainly in maxillary lateral incisors. Often this condition predisposes periodontal defects and severe bone destruction, which have been considered untreatable, and extraction has been recommended as a solution. In this report a case is presented of a radicular palatal groove in a maxillary lateral incisor that caused an advanced periodontal defect and pulp necrosis. Like other such cases, this case presented first as an endodontic problem, and was diagnosed by the endodontist. Periodontal surgery failed to resolve the lesion. Filling of the groove by means of amalgam resulted in disappearance of symptoms and closure of the pocket, accompanied by restoration of the lamina dura. The suggested technique was advantageous over previously published treatment modalities, as it effectively eliminated the groove as a pathway of contamination, without loss of tooth substance and without exposure of cut dentin. It is also suitable for treating deep grooves communicating with the root canal.     

Surgical Anatomy of the Recurrent Laryngeal Nerves and its Clinical Applications in Chinese Adults

PURPOSE: When removing the thyroid gland, great care must be taken to avoid damaging the recurrent laryngeal nerves (RLNs). The present study aims to present a clear picture of certain anatomical features of the RLNs in relation to the inferior thyroid artery (ITA), the tracheoesophageal groove (TE), Berry's ligament, and the inferior cornu of the thyroid cartilage in Chinese adults. METHODS: We removed a collective 120 RLNs from 60 Chinese adult cadavers (52 men and 8 women), and examined their anatomic course and relationship on both sides. RESULTS: The right and left RLNs were found in the tracheoesophageal groove in 78.3% and 91.3% of cases, respectively. Both RLNs were found posterior to and to the right of the ITA in 80% of cases, and one was found on the left side of the ITA in 91.7%. Most of the RLNs were within 3 mm of Berry's ligament, with a laryngeal entry point about 0.8 cm below and just anterior to the inferior horn of the thyroid cartilage. CONCLUSIONS: The inferior cornu of the thyroid cartilage is a reliable landmark in identifying the RLNs. Racial variations between Caucasians and Chinese may explain some anatomic differences.     

凹槽梯形枕在髋关节置换术后患者中的应用效果

目的探讨凹槽梯形枕在髋关节置换术后患者中的应用效果。方法选择2006年1月-2010年1月本院收治行髋关节置换术后患者240例,按照术后顺序的单双号分为对照组和实验组,每组各120例。对照组患肢术后应用皮牵引套牵引固定加普通枕头垫高,实验组患肢采用凹槽梯形枕垫高,比较两组患者术后并发症的发生率。结果两组患者术后并发症发生率比较,均P<0.05,差异具有统计学意义,实验组术后并发症的发生率低于对照组。结论在髋关节置换术后采用凹槽梯形枕垫高患肢,能起到良好固定关节的作用,可降低并发症的发生率,提高患者的护理质量,从而促进患者早日康复。

嵌趾甲病因分析与防治探讨

目的:探讨嵌趾甲的病因及防治方法。方法:回顾分析我院采用趾甲生长引导术治疗的28例嵌趾甲患者的临床资料。结果:28例患者的趾甲形状均为拱形,甲床相对趾腹均过短,均发病于趾甲厚硬的拇趾。患者都有过度剪趾甲习惯。对28例嵌趾甲患者采用趾甲生长引导术治疗,经9~18个月随访,28例全部治愈。结论:趾甲形状、生活习惯是嵌趾甲发病的重要因素,趾甲生长引导术可以有效治疗嵌趾甲。     

下颌第一前磨牙根面沟的形态分析

目的:下颌第一前磨牙多为单根单管,少见变异形态尤其是三根以上极为罕见,本文对其变异牙根形态进行观察分析,为根管治疗术前检查诊断提供参考。方法:从收集的83颗下颌第一前磨牙离体牙中选出具有根面沟、根面凹陷及根尖分叉的15颗,对牙根外形进行拍摄并仔细观察分析。结果:83颗下颌第一前磨牙牙根变异15颗(18%);变异牙根均可见近中舌侧沟;根面沟主要发生在根中下段;颊舌侧根面沟罕见,可同时伴有根尖分叉;其中单根尖牙75颗(90.4%),双根尖以上6颗(7.2%)。结论:根面沟的发生使得下颌第一前磨牙牙根及根管形态变得复杂,根管治疗前应仔细检查以免遗漏根管。     

甲床甲沟部分切除加残留甲床部分剥离甲沟重建术的临床研究
