Introduction.The temporomandibular joint (TMJ) is the most complex elegantly designed joint in the human body. Abnormal development and growth of TMJ may lead to condyle aplasia present in several syndromes expressions, but it is extremely rare when not connected to any underlying pathological disorder or in conjunction with any syndrome.Objective.A rare case of aplasia of the mandibular condyle is presented, along with 3D computed tomography (3D CT) findings.Conclusion.Based on clinical and radiological findings we suggest the abnormal development of the TMJ as the origin. The 3D CT has provided high-quality images, which made diagnosis and a prompt treatment plan possible.

ABSTRACT Coronoid Process Hyperplasia is a rare condition characterized by the increase in size of a histologically normal bone. It can be confused with Temporomandibular Joint Dysfunction, due to the presence of major signs/symptoms, including the limitation of mouth opening, pain, and facial asymmetry. Although several theories have been proposed, the etiology remains unknown. The recommended treatment is mandibular coronoidectomy. In the present study, the importance of computed tomography to reach the proper diagnosis and the surgical treatment plan is demonstrated.

Computed tomography (CT) has been increasingly used in the examination of patients with craniofacial trauma. This technique is useful in the examination of the temporomandibular joint and allows the diagnosis of fractures of the mandibular condyle. Aiming to verify whether the three-dimensional reconstructed images from CT (3D-CT) produce more effective visual information than the two-dimensional (2D-CT) ones, we evaluated 2D-CT and 3D-CT examinations of 18 patients with mandibular condyle fractures. We observed that 2D-CT and 3D-CT reconstructed images produced similar information for the diagnosis of fractures of the mandibular condyle, although the 3D-CT allowed a better visualization of the position and displacement of bone fragments, as well as the comminution of fractures. These results, together with the possibility of refining and manipulating perspectives in 3D images, reinforce the importance of its use in the surgical planning and evaluation of treatment. We concluded that 3D-CT presented supplementary information for a more effective diagnosis of mandibular condyle fractures.

Introduction. The bifid mandibular condyle (BMC) is an unusual temporomandibular joint (TMJ) disorder with controversial etiology. The association of this entity with ankylosis is rare. Objective. The objective of the present study is to report a case of BMC with associated TMJ ankylosis in a patient with no history of trauma and/or infection. Case Report. A 17-year-old male patient sought care reporting pain on the right TMJ region and mastication difficulty due to a severe limitation of mouth opening. In the clinic and imaging examinations, a 15 mm mouth opening and BMC associated with ankylotic mass of the right TMJ were observed, besides a facial asymmetry with chin deviation to the right. The proposed treatment plan was condylectomy on the right side, bilateral coronectomy, and genioplasty, so the chin lateral deviation could be corrected, under general anesthesia. The patient remains under clinical and imaging follow-up of two years with functional stability and no signs of relapse of the ankylosis. Conclusion. The association of BMC with ankylosis is an atypical entity which must be diagnosed and treated early to prevent aesthetic and functional damages to the patient.

Fusion is a developmental anomaly characterized by the union of two adjacent teeth. In this paper we report a rare case of fusion involving permanent mandibular second molar with supernumerary tooth. The rarity with which this entity appears, along with its complex characteristics, often makes it difficult to treat. The use of high-end diagnostic imaging modalities such as spiral computed tomography can help the clinician in making a confirmatory diagnosis and determining the treatment plan before undertaking the actual treatment. In the present case, we have used spiral computed tomography (SCT) for better understanding the complicated root canal morphology of the fused tooth and successful management of this rare case.

Purpose: The aim of this article is to describe and illustrate the appearance of craniosynostosis on CT scan images. Methods: A total of 60 children during the years 2014-2018 were included. The medical and radiographic records of patients less than 3 years of age, clinically diagnosed with nonsyndromic craniosynostosis were studied. They underwent CT imaging examination in order to confirm the diagnosis and to accurately establish the surgical treatment plan. Results: The high diagnostic performance of CT with 3D surface-rendered reconstructions was pointed out together with the most common findings. Conclusion: 3D CT appears as the imaging modality with the best diagnostic performance in children with craniosynostosis. However, large prospective studies and further research are needed, in order to clearly define the role of 3D CT and minimize the unnecessary exposure of infants to radiation.

Abstract Background The vertical thickness of the peri-implant mucosa is associated with the amount of post treatment marginal bone loss. However, the variations in mucosal thickness at the different edentulous sites have been sparsely documented. The purpose of the study was to conduct a survey of the frequency distribution of variations in mucosal thickness at the different sites of the edentulous alveolar ridge and to compare them according to gender. Our study included 125 partially edentulous patients having a total of 296 implant sites. Cone-beam computed tomography (CBCT) scans were obtained by placing a diagnostic template with a radiopaque crown indicator on the ridge to determine the mucosal thickness at the crest of the alveolar ridge. Results The mucosal thickness was 3.0±1.3 mm in the maxilla, which was significantly greater than the mucosal thickness of 2.0±1.0 mm in the mandible (p<0.001). In both the maxilla and the mandible, the mucosa was the thickest in the anterior region, followed by the premolar and molar regions. Sites were further classified into two groups based on whether the mucosal thickness was greater than 2 mm. In the mandible, more than half of the sites showed a mucosal thickness of 2 mm or less. Conclusions Although this study was a limited preoperative study, the vertical mucosal thickness at the edentulous ridge differed between the maxillary and mandibular regions. The majority of sites in the mandibular molar region had a mucosal thickness of less than 2 mm. Practitioners might be able to develop an optimal dental implant treatment plan for long-term biologic and esthetic stability by considering these factors.

Abstract Purpose Bochdalek's hernia is a type of congenital diaphragmatic hernia occurring secondary to a defect in the posterior attachment of diaphragm. This condition commonly presents with respiratory insufficiency in infants. To date, there are less than 100 cases of Bochdalek's hernia presenting in adults published in the literature. The mainstay treatment of Bochdalek's hernia involves reduction of hernial contents back into the peritoneal cavity with a tensionless graft repair closing the diaphragmatic defect. Case Presentation We present an atypical case of the Bochdalek hernia presenting in a previously healthy 16-year-old male who presented to the Accident and Emergency department with a 2-day history of dysphagia and loss of breath. The Bochdalek hernia was confirmed on computed tomography (CT) imaging and the patient underwent surgical repair with Gore-Tex mesh. Conclusion The report shows a rare case of the Bochdalek hernia in a young adult, successfully managed with a laparotomy.

Bonebridge (BB) is the first active implantation system for bone conduction that is placed fully under the skin. Experience suggests that BB is characterized by low incidence of postoperative complications. This case report presents a rare case of a 16-year-old girl with incidence of emphysema occurring over the implant 1 year after operation. We performed a computed tomography scan that showed pockets of gas above the floating mass transducer so we provided the revision surgery and sealed the artificial opening with fat from the earlobe and fibrin glue. Since that time, no air has collected in the retroauricular area and the implant has been fully functional.

Tarsometatarsal Joint

Background Fibrocartilaginous coalition of the third tarsometatarsal joint has been indicated as an extremely rare form of tarsal coalition in the radiological literature, and most articles concerned with tarsal coalition do not mention involvement of this joint. Only two reports written in the English language that approach this subject were found, an orthopedic report and an anthropological report. Purpose To evaluate the prevalence of this finding and discuss and illustrate the radiological characteristics of this coalition. Material and Methods A retrospective analysis of 614 computed tomography or magnetic resonance imaging scans of the ankle and/or foot, acquired at a health service within a period of three months, was performed to assess the prevalence of this coalition. Results Of the examinations characterized as valid for analysis for the purposes of the study, 17 cases compatible with fibrocartilaginous coalition of the third tarsometatarsal joint were found, thus indicating an involvement of approximately 2.97% of the examined feet. Conclusion Our radiological findings are typical, and the prevalence found in this study was statistically significant, being similar to that described in the anthropological report (3.2%–6.8%).

Score Inflation

Introduction Extensive research relying on Injury Severity Scores (ISS) reports a mortality benefit from routine non-selective thoracic CTs (an integral part of pan-computed tomography (pan-CT)s). Recent research suggests this mortality benefit may be artifact. We hypothesized that the use of pan-CTs inflates ISS categorization in patients, artificially affecting admission rates and apparent mortality benefit. Methods Eight hundred and eleven patients were identified with an ISS >15 with significant findings in the chest area. Patient charts were reviewed and scores were adjusted to exclude only occult injuries that did not affect treatment plan. Pearson chi-square tests and multivariable logistic regression were used to compare adjusted cases vs non-adjusted cases. Results After adjusting for inflation, 388 (47.8%) patients remained in the same ISS category, 378 (46.6%) were reclassified into 1 lower ISS category, and 45 (5.6%) patients were reclassified into 2 lower ISS categories. Patients reclassified by 1 category had a lower rate of mortality ( P < 0.001), lower median total hospital LOS ( P < .001), ICU days ( P < .001), and ventilator days ( P = 0.008), compared to those that remained in the same ISS category. Conclusion Injury Severity Score inflation artificially increases survival rate, perpetuating the increased use of pan-CTs. This artifact has been propagated by outdated mortality prediction calculation methods. Thus, prospective evaluations of algorithms for more selective CT scanning are warranted.
