    髁突骨髓炎是下颌骨髁突的长期感染。这种疾病的慢性进展可导致周围骨结构的破坏,并最终影响功能。目前,英国文学,关于髁状突骨髓炎的病例很少。有趣的是,无论接近,上颌第三磨牙拔除后,仅有另外两例报告的髁突骨髓炎病例。我们报告了一例27岁的女性,该女性在简单地拔除左上第三磨牙后出现con突骨髓炎的急性发作。几个疗程的抗生素并没有缓解她的严重的三嘴,感觉异常,或广泛的耳前收集。三种手术干预在许多拭子上显示出负增长。然而,CT扫描和MRI证实左头广泛的骨髓炎,脖子,和下颌骨的角度。住院患者静脉注射抗生素后,患者使用PICC管路出院,以便接受长期治疗.功能的改进,疼痛,出院时出现肿胀。然而,由于这种疾病的性质,她被监测了2年,由于关节塌陷已被列为同种异体置换术。
    Condylar osteomyelitis is a long-standing infection of the condylar head of the mandible. The chronic progression of this disease can lead to the destruction of surrounding bony structures and can ultimately affect function. Currently, in English Literature, there have been few cases published on condylar osteomyelitis. Interestingly, regardless of proximity, there have only been two other reported cases of condylar osteomyelitis subsequent to extractions of the upper maxillary third molar. We report a case of a 27-year-old female who presented with an acute episode of condylar osteomyelitis after a simple extraction of an upper left third molar. Several courses of antibiotics did not alleviate her severe trismus, paresthesia, or extensive preauricular collection. Three surgical interventions showed negative growth on numerous swabs. However, CT scans and an MRI confirmed extensive osteomyelitis along the left head, neck, and the angle of the mandible. Following inpatient IV antibiotics, the patient was discharged with a PICC line to allow for long-term treatment. An improvement in function, pain, and swelling was seen on discharge. However, due to the nature of this disease she was monitored for 2 years and due to joint collapse has been listed for alloplastic replacement.

    髁突移位和重塑是与正颌手术密切相关的现象,并与咬合和骨骼稳定性密切相关。本病例报告的目的是描述成年患者的双侧劈开矢状面截骨术(BSSO)后随着时间的推移,髁突移位和表面重塑。我们观察到一位21岁的男性。口外检查显示对称的方形脸,一个凸起的轮廓,一个锐利的鼻唇沟角和一个深的唇瓣折。口内检查显示为II类2,下颌中线向左偏离2mm,并且在象限II和III之间存在双尖牙的剪刀咬伤。Spee曲线和过咬(OV14.3mm)与过喷(11.1mm)非常突出。CBCT的轴向重建显示两个髁的正常形状和位置。头影测量分析显示面部高度降低,正常的上颌位置,下颌骨发育不全,被发达的联合和极低的发散(FMA11.2°)掩盖。在正畸治疗的第13个月进行了BSSO治疗下颌挫折。术前原始CBCT数据(T0),在治疗结束时(T1),收集术后2年(T2)和术后5年(T3)并重建以进行3维(3D)定性分析。在手术-正畸治疗结束时(26个月),实现了良好的功能和良好的美学。在T0,T1,T2,T3时对CBCT进行的叠加和切割的定性和比较分析显示,髁的生理重塑和适应。
    Condylar displacement and remodelling are phenomena closely related to orthognathic surgery and critically involved in occlusal and skeletal stability. The aim of the present case report is to describe over time condylar displacement and surface remodelling after bilateral split sagittal osteotomy (BSSO) in an adult patient with severe class II skeletal malocclusion treated with ortho-surgical approach. A male of 21years comes to our observation. The extraoral examination shows a symmetrical square-shaped face, a convex profile, an acute nasolabial angle and a deep labiomental fold. Intraoral examination reveals a class II division 2 with a 2mm deviation of the mandibular midline to the left and the presence of a scissor bite of the bicuspids between quadrants II and III. The Spee curve and overbite are extremely accentuated (OV 14.3mm) as the overjet (11.1mm). Axiographic reconstructions of CBCT show a normal shape and position of both condyles. The cephalometric analysis shows a reduced lower facial height, a normal upper jaw position, a mandibular underdevelopment masked by a very developed symphysis and an extremely low divergence (FMA 11.2°). BSSO for mandibular setback was performed in the 13th month of orthodontic therapy. Original CBCT data before surgery (T0), at the end of treatment (T1), 2years postoperatively (T2) and 5years postoperatively (T3) were collected and reconstructed for 3-dimensional (3D) qualitative analyse. At the end of the surgical-orthodontic treatment (26months), good function and good aesthetics were achieved. The qualitative and comparative analysis of the superimpositions and the cuts made on the CBCT at T0, T1, T2, T3 showed a physiological remodelling and adaptation of the condyles.

    UNASSIGNED:颞下颌关节(TMJ)的滑膜软骨瘤病的特征是由于滑膜的化生发育而形成大小不同的多个软骨结节。病因与原发病变有关,多因素的发病机制尚不清楚,包括低级创伤或内部紊乱。这种情况仍未诊断,并导致非特异性临床表现的治疗挑战,需要各种工具来结合放射学和组织病理学检查进行诊断。
    UNASSIGNED:我们报告了一个病例系列,其中5例被诊断为颞下颌关节TMD。诊断性关节镜检查包括用Ringers乳酸溶解和灌洗,进行透明质酸。术中发现提示滑膜软骨瘤病。组织病理学检查的样本证实了TMJ滑膜软骨瘤病的诊断。术后15天评估张口和疼痛的状态,一个月,3个月,6个月和1年期间复查评价关节镜对颞下颌关节的成功。
    UNASSIGNED:所有患者在随访12个月时报告关节镜松解术和灌洗方式成功,每次随访时在运动范围和VAS疼痛评分方面均有所改善。因此,在TMJ滑膜软骨瘤病的情况下,关节镜下的松解术和灌洗术是开放关节手术的一种有希望的替代方法,在缓解抱怨最大切口间开放和疼痛减少的患者方面具有相同的效果。
    未经批准:因此,关节镜手术可以被认为是成功治疗颞下颌关节滑膜软骨瘤病的另一种有效方法。
    UNASSIGNED: Synovial chondromatosis of the temporomandibular joint (TMJ) is characterized by the formation of multiple nodules of cartilage with varying sizes due to metaplastic development of the synovial membrane. Aetiology revolves with primary lesion, and pathogenesis is still unknown with multiple factors, which includes low-grade trauma or internal derangement. This condition remains undiagnosed and leads to therapeutic challenges from clinical manifestations which are non-specific and needs various tools to diagnose with combination of radiologic and histopathological examination.
    UNASSIGNED: We report a case series of five cases which were diagnosed as cases of TMD of the temporomandibular joint. Diagnostic arthroscopy including lysis and lavage with Ringers lactate, hyaluronic acid was carried out. Intra-operative findings were suggestive of synovial chondromatosis. Sample taken for histopathological examination confirmed the diagnosis of synovial chondromatosis of TMJ. Postoperative status of mouth opening and pain was assessed at 15 days, one month, 3 months, 6 months and one year during the review to evaluate the success of arthroscopy of TMJ.
    UNASSIGNED: All patients reported success with the modality of arthroscopy lysis and lavage at 12 months of follow-up with improvement at every follow-up visit in terms of range of motion and reduction of pain score on VAS. Hence, arthroscopy with lysis and lavage came out to be a promising alternative for open joint surgery in cases of synovial chondromatosis of the TMJ with same outcomes in relieving patients who complain of reduced maximum inter-incisal opening and pain.
    UNASSIGNED: Thus, arthroscopic procedures can be considered an alternative and effective modality for successful management of cases of synovial chondromatosis of temporomandibular joint.

    中央巨细胞肉芽肿(CGCG)在下颌髁中并不常见。在青少年中,由于诊断和治疗涉及下颌过程的潜在生长和面部发育的困难,该问题更加复杂。在这份简短的通讯中,介绍了一名11岁的女性,其诊断为中央巨细胞肉芽肿,影响下颌髁突,在第一次和随后的正颌手术中,分两步进行了髁突切除术和垂直支截骨术,显示13年随访后的临床演变。此外,我们对下颌髁突CGCG相关的科学报告进行了回顾,以将这种治疗与其他治疗方法进行比较,在后续行动和结果方面。我们的结论是,影响下颌头的CGCG可以通过低位条件切除术来正确治疗,垂直下颌支滑动截骨术,和双性恋。
    Central giant cell granulomas (CGCG) are not common in the mandibular condyle. In teenagers, the problem is more complex because of difficulties in diagnosis and treatment involving the potential growth of the mandibular process and development of the face. In this short communication a case is presented of an eleven-year-old female under diagnosis of central giant cell granuloma affecting the mandibular condyle treated surgically in two steps using a condylectomy and vertical ramus osteotomy at the first time and later orthognathic surgery, showing the clinical evolution after 13 years of follow-up. In addition, we performed a review of the scientific reports related to CGCG in the mandibular condyle to compare this treatment with others, in terms of follow-up and results. We concluded that the CGCG affecting the mandibular head can be properly treated with low condilectomy, vertical mandibular ramus sliding osteotomy, and discopexy.

    手术治疗颞下颌关节脱位合并气动关节隆起对外科医生来说是一项技术挑战。因为这种情况的人口频率很低。本文旨在介绍一例患有双侧气动关节隆起的患者,通过微型钢板成形术治疗复发性颞下颌关节脱位。经过15个月的随访,患者出现约43毫米的切间距离。微型钢板保持原位,没有骨折迹象,并且有令人满意的临床进展,没有更多的脱位发作。已证明,微型钢板治疗颞下颌关节脱位对双侧气动关节隆起的患者有效。虽然,需要更多的时间来评估长期有效性。
    Performing a surgical treatment for TMJ dislocation combined with pneumatized articular eminence is a technical challenge for the surgeon, as this condition has a low population frequency. This article aimed to present one case of recurrent temporomandibular joint dislocation treated by eminoplasty with miniplates in a patient affected by bilateral pneumatized articular eminence. After 15 months of follow-up, the patient presented approximately 43 mm of interincisal distance. The miniplates remained in position with no fracture signs, and there was satisfactory clinical evolution with no more dislocation episodes. Eminoplasty with miniplates for the treatment of temporomandibular joint dislocation has been shown to be effective in a patient affected by bilateral pneumatized articular eminence. Although, more time is needed to evaluate long-term effectiveness.

    The aim of this study was to evaluate and discuss the long-term outcomes of patients with condylar osteochondroma managed through 3 different surgical techniques. Seven patients with condylar osteochondroma treated in the author\'s department from May 2012 to January 2019 were included in this retrospective study. Clinical evaluations (visual analogue scale for TMJ pain, jaw function, symmetry, and quality of life), maximum interincisal opening (MIO) and radiological findings were collected pre- and postoperatively. Other parameters assessed included tumour size and location; complications and follow-up. Radical condylectomy with immediate total joint alloplastic reconstruction was performed in 4 patients, local excision in 2 patients and low condylectomy with concomitant orthognathic surgery in 1 patient. During an average follow-up period of 40,8 months no clinical or radiographic signs of recurrence were found. Average MIO increased from 25,5mm to 39,5mm at the longest follow up, and all clinical evaluations were greatly improved. In conclusion, the described surgical techniques appear valuable in the treatment of condylar osteochondroma. Local excision is indicated in tumor involving less than half the surface of the condylar head; radical condylectomy with immediate alloplastic total joint reconstruction is indicated in gigantic lesion compromising the anatomical components and function of the joint. Orthognathic surgery procedures should be combined with tumor resection when correction of associated dentofacial deformities is indicated.

    本文介绍了一例罕见的急性错牙合畸形病例,该病例是由翼外肌单侧部分撕裂引起的,并对其病理学进行了最新文献综述。
    检查了一名37岁的女性;她的主要主诉是颞下颌关节(TMJ)区域右侧的疼痛以及与主要咬合修改和前开放咬合相关的咀嚼障碍。在TMJ的磁共振成像(MRI)和锥形束计算机断层扫描(CBCT)以及随后的软组织MRI之后,最终诊断为部分右侧翼外肌撕裂。
    该病例显示了联合成像在颞下颌关节紊乱病(TMD)中的价值以及除关节检查外的软组织评估的重要性,因为主要病理可能位于关节外。作者对当前文献的回顾迄今没有发现类似的案例。
    UNASSIGNED: The article presents a rare case of acute malocclusion produced by a unilateral partial tear of the lateral pterygoid muscle and an up-to-date literature review of the pathology.
    UNASSIGNED: A 37-year-old female was examined; her chief complaints were pain on the right side of the temporomandibular joint (TMJ) area and mastication impairment associated with major occlusal modifications and anterior open bite. After magnetic resonance imaging (MRI) and cone beam computed tomography (CBCT) of the TMJ and subsequent MRI for soft tissue, the final diagnosis was a partial right lateral pterygoid muscle tear.
    UNASSIGNED: The case shows the value of combined imaging in temporomandibular disorders (TMD) and the importance of soft tissue evaluation in addition to articular examination, as the primary pathology might lie outside the joint. The authors\' review of the current literature did not hitherto reveal a similar case.

    在晚期病例中,针对患者特定的TMJ置换的计算机引导方法被认为是最终可靠的选择。然而,凹陷的窝设计可能会发生con头脱位。在这种情况下描述并使用了平面设计。
    方法:一名15岁的男性患者,下颌骨不对称和IV级复发性右TMJ强直,接受了患者专用的人工关节,并进行了计算机引导的间隙关节成形术和正颌矫正手术。窝部分是完全平坦的,患者在接下来的一年中接受了随访。
    定制的TMJ假肢解决方案在高级情况下是可靠的,尤其是当显示面部矫正时;然而,常用的凹面设计显示,报告的位错需要一些设计修改,在提出的情况下。
    结论:人造TMJ的平坦窝设计确保了与解剖窝设计相同的结果,而没有脱位的发生。
    UNASSIGNED: The computer-guided approach for the patient-specific TMJ replacement is considered an ultimate reliable option in advanced cases. However, dislocation of the condylar head could happen with the concave fossa design. A flat design was described and used in this case.
    METHODS: A 15 years old male patient with mandibular asymmetry and class IV recurrent ankylosis of the right TMJ received a patient-specific artificial joint with computer-guided gap arthroplasty and orthognathic corrective mandibular surgery for the left side. The fossa component was made entirely flat, and the patient was followed up over the next year.
    UNASSIGNED: Customized TMJ prosthetic solutions are reliable in advanced cases, especially when facial corrections are indicated; however, the commonly used concave design showed reported dislocations requiring some design modifications as proposed in the presented case.
    CONCLUSIONS: The flat fossa design of the artificial TMJ secures the same results as the anatomical fossa design without the incidence of dislocation.

    Pigmented villonodular synovitis (PVNS) is a benign proliferative disorder of the synovium that usually involves joints, tendon sheaths, and bursae. It presents rarely, however, in the temporomandibular joints (TMJs). This paper reports a 59-year-old female patient with PVNS of the TMJ and its clinico-pathologic features are discussed. The patient was treated with surgery and postoperative radiotherapy (PORT). Follow-up was conducted, and there were no recurrences, metastases, skin changes or joint stiffness noted. The main treatment of PVNS is surgical resection. However, postoperative radiotherapy is important for local control of extensive tumors or positive margins. We conducted a literature review for postoperative radiotherapy case reports related to PVNS of the TMJ.
