Condylar Head

Treatment of mandibular condyle fractures is still controversial, with surgical treatment slowly becoming the preferred option. However, fractures of the condylar head (diacapitular fractures) are still treated conservatively at many institutions. Recently, more and more surgeons have begun to perform open treatment for diacapitular fractures because it allows to restore the anatomical position of the fragments and disc, it allows an immediate functional movement of the jaw, and avoid the ankylosis of the temporomandibular joint induced by the trauma. Several techniques have been proposed to reduce and fix fractures of the condylar head, such as standard bone screws, resorbable screws, resorbable pins, and cannulated lag screws. Therefore, the aim of this article is to review the literature about the surgical treatment of fractures of the condylar head to resume the current knowledge about open treatment of such fractures.

Condylar Fractures

Intracapsular condylar fractures may account for 65% of all condylar fractures. This diversity of classifications makes epidemiological data collection challenging. Historically, intracapsular condylar fractures were treated in a closed or conservative manner, without open surgery and fixation of the bone fragments. Closed treatment has been described with acceptable outcomes without the risk of complications associated with the surgical treatment, that is, infection, damage to the facial nerve, and unaesthetic extra-oral scar. Recently, studies reporting the surgical treatment of condylar head fractures have reported better results regarding mandibular functional aspects, dental, and aesthetic results. It is also suggested that the repositioning of the articular disc during the surgical procedure, could prevent the consequences of its displacement in possible temporomandibular joint dysfunctions. The objective of this study is to report a clinical case of intracapsular condylar head fracture with open treatment, using lag screw fixation according to AO/ASSIF (Arbeitsgemeinschaft für Osteosynthesefragen/Association for the Study of Internal Fixation) protocols and recommendations.

Data suggest that adjuvant human papillomavirus (HPV)-vaccination in women treated for cervical HPV diseases reduces recurrent disease. This study investigates adjuvant HPV-vaccination and the rate of recurrence in women undergoing surgery for vulvar high-grade squamous intraepithelial lesions (HSIL). From January 2013 to April 2020, we enrolled 149 women in a prospective case-control study. The control group (NV-group) was treated by standard surgery alone, while the study group received adjuvant vaccination soon after surgery (V-group). A follow-up was performed by vulvoscopy and HPV test. Statistical analysis was performed by Fisher’s exact test. HSIL recurrence was observed in 24/76 (32%) patients in NV-group and in 8/42 patients (19%) of the vaccinated group. By analysing the recurrence rate related to the incident and reactivated latent HPV infection, we found a significant difference between (17/76) 22.3% in NV-group and (2/42) 4.8% in V-group (p = 0.01). A reduction of 78.5% in incident/reactivated HPV infections was demonstrated. Data results add to the current knowledge about the mechanism of post-surgical adjuvant HPV vaccination. Our prospective study is the first to document the vaccine clinical effectiveness in preventing “reactivation” of latent HPV infections. Quadrivalent HPV vaccine administered after the surgical treatment for vulvar HSIL appears to be useful in preventing recurrent disease.

Abstract Background Rheumatoid arthritis of the temporomandibular joint (TMJ-RA) has been reported to have a larger incidence range than systemic rheumatoid arthritis (RA). The presence or absence of mechanical stress (MS) is considered a factor in this. In this study, we hypothesized that TMJ-RA develops or worsens when excessive MS is applied to the temporomandibular joint of RA mouse models. We aimed to clarify the relationship between TMJ-RA and MS through morphological and histological evaluation. Methods Collagen antibody-induced arthritis (CAIA) was induced in male DBA/1JNCrlj 9–12 weeks old mice by administering Type II collagen antibody and lipopolysaccharide to produce RA model mice. MS was applied to the mandibular condyle. The group was separated into non-RA (control group (N = 5) and MS group (N = 5)), and RA group (CAIA group (N = 5)and CAIA MS group (N = 5)). To confirm the morphological changes in the mandibular condyle, micro-CT imaging was performed. Histological evaluation of the TMJ was performed by hematoxylin and eosin staining for condylar cartilage cell layer thickness, Safranin O staining for proteoglycans, and tartrate-resistant acidic phosphatase staining for osteoclast count. Immunohistochemical evaluation was performed to assess the localization of cartilage destruction enzymes using ADAMTS-5 (a disintegrin and metalloproteinase with thrombospondin motifs) antibody. Additionally, CD3 (cluster of differentiation), CD45, and γδ TCR (T cell receptor) antibodies were used to localize and identify the type of lymphocytes. Results In the CAIA MS model, a three-dimensional analysis of the temporomandibular joint by microcomputer tomography showed a crude change in the surface of the mandibular condyle. Histological examination revealed a decrease in the chondrocyte layer width and an increase in the number of osteoclasts in the mandibular condyle. T cell accumulation was observed, and γδ T cell involvement was confirmed. Conclusions In the CAIA model, the TMJ was less sensitive to the initiation of RA. However, the results suggested that it was exacerbated by MS, and that γδ T cells may be involved in TMJ-RA.
