山羊髁突刨削术后髁突软骨面修复的初步观察

目的:观察山羊髁突刨削术后髁突的愈合过程。方法:实验动物7只山羊,将6只山羊两侧髁突软骨面磨除,另1只未做手术为正常对照。分别于术后4、8、12周;每个时间点取材2只实验动物进行HE染色加以评价。结果:术后4周山羊髁突软骨缺失区粗糙,为骨样及一些纤维样组织修复,或可见少许纤维样软骨;术后8周及12周髁突表面较术后4周时光滑,修复组织逐渐变为以骨性组织为主,软骨样成分逐渐消失。结论:经过关节髁突的刨削术,术后3个月时,实验动物髁突软骨缺失区不能形成正常的软骨组织。

青少年髁状突骨折保守治疗的X线追踪观察

青少年正处在骨骼发育旺盛期,骨折修复能力很强,保守治疗下颌骨髁状突骨折仍被大多数作者采用。许多文献报道保守治疗髁状突骨折常有咀嚼功能损伤、面部两侧不对称、颞下颌关节强直等并发症的发生。本文作者通过对青少年髁状突骨折保守治疗患者的X线片追踪观察,来了解年龄、骨折类型对骨折愈合的影响。

髁突骨折治疗效果观察与评价

下颌骨髁状突为骨折的好发部位。通常，髁突骨折多采用保守治疗，即颌间牵引固定。近年来，随着内固定材料和技术的发展，临床上开始采用手术复位固定治疗。本研究拟对这两种治疗方法的效果进行评估。材料和方法资料来源：１９７８～１９９５年华西医大口腔医院诊断治疗的...     

髁突缺损的修复重建

髁突缺损多发生于肿瘤、外伤、炎症以及先天畸形等手术术后。髁突重建长期以来是修复重建领域难点,原因在于它与颌面部唯一能动关节—颞颌关节息息相关,而颞颌关节直接参与咀嚼、语言等重要功能。在髁突重建中如何使这些重要功能得以保存,修复方法如何选择以及各自手术要点,这些都是临床医生关注的问题。本文综述髁突重建研究文献,以期能对相关问题做一解答。

Trifid mandibular condyle: A case report

A few cases of bifid, but no case of trifid mandibular condyle, have been reported in the literature. This article presents the first reported case of trifid mandibular condyle in a living subject with a history of previous trauma to the temporomandibular joint (TMJ). Additionally, the patient's other condyle was bifid. The patient had no complaint related to the functions of TMJ except for minimal weakness following chewing. The etiology and the prognosis of bifid and trifid condyle are discussed briefly. We considered computed tomography essential to rule out early stages of TMJ pathology in similar cases that resemble trifid mandibular condyle on conventional radiographs.     

Bifid mandibular condyle: a case report

The bifid mandibular condyle is a rare anomaly. A variety of causes are implicated with its development such as developmental origin and trauma. Because of the lack of epidemiological data, there is little information about the real incidence of this malformation. The purpose of this paper is to report a case of bifid mandibular condyle in a 20-year-old woman who referred to a private radiological clinic for routine dental examination. A panoramic radiography incidentally revealed a discrete modification of the left mandibular condyle. Magnetic resonance imaging (MRI) was taken and confirmed the diagnostic proposed.     

Bifid mandibular condyle: a case report

Abstract –  A case of left bifid mandibular condyle (BMC) is reported in a 36-year-old female. The patient had a history of trauma in childhood. From the radiological examination, the left condyle was seen to have two anterioposteriorly situated heads. BMC is an extremely rare condition, where the condyle is duplicated or lobulated. The literature on BMC is reviewed, and possible cause of trauma and consequences of the anomaly are discussed.     

Trifid mandibular condyle: a case report

A suspected case of trifid mandibular condyle that was observed on a panoramic radiograph and confirmed using computed tomography (CT) is reported. No history of previous temporomandibular joint (TMJ) trauma was reported by the subject.     

Osteochondroma of the mandibular condyle. A case report.

A 52-year-old woman presented with pain on the right temporal region, restricted mandibular movement and a gradually developing malocclusion. Osteochondroma of the mandibular condyle was suspected based on diagnostic imaging. Local resection with preservation of the condylar head resulted in complete resolution of symptoms.     

Bilateral bifid mandibular condyle: a case report

Bilateral bifid mandibular condyle is a rarely seen malformation. The aetiology of bifid condyle is not completely understood, although developmental anomaly, traumas, condylar fracture, teratogenic embryopathy and surgical condylectomy may all be causative factors. Although a few studies on human dried skulls tried to shed light on this entity it remains obscure. As most bifid condyle subjects have no complaint related to temporamandibular joint(TMJ), the cases are generally diagnosed through incidental radiographic findings. The case of a 54-year-old female is presented. In a panoramic radiograph obtained after a clinical examination, bilateral bifid mandibular condyle was observed. The open-closed lateral radiograph of the TMJ (obtained using the TMJ-specific program of the panoramic device) demonstrated duplication of the right and left condyles. In order to better evaluate the TMJ morphology and to eliminate pathologies such as fractures that might be missed with conventional radiographs, a computed tomography scan was also obtained. The joint head orientation was observed in the mediolateral direction. The case is discussed in the context of the relevant literature. Until large population-based studies are undertaken and further experimental studies are performed, bifid condyle will remain an incidental finding of anatomic variation rather than a clinically informative observation.     

Unilateral trifid mandibular condyle: a case report

Trifid mandibular condyle is an exceptionally rare entity, diagnosed accidentally on radiographic examination. Its etiology is controversial. Dental professionals should have knowledge of this anatomic abnormality and of the problems caused by it in normal function, as well as appropriate treatment modalities. In the literature, only three such cases have been reported. The current case report (the fourth reported) is of a unilateral trifid condyle reported in a 37-year-old woman seeking treatment for a missing tooth. A panoramic radiograph accidentally revealed a discrete modification of the right mandibular condyle. Computed tomography (CT) with 3-D construction was done to confirm the diagnosis.     

Bifid mandibular condyle: case report and etiological considerations

Bifid mandibular condyle, usually diagnosed on routine radiographic examination, is described in the literature as a rare entity. Its cause is controversial, and it has no predilection by sex or ethnic background. Dental professionals should have some knowledge of this anatomic abnormality, as well as its implications for function and appropriate treatment modalities, so that they can be alert to this potential diagnosis. This paper reports an unusual case of bifid mandibular condyle with possible traumatic cause, with emphasis on the radiographic and tomographic findings.
