Osteoma cutis (OC) is a rare benign disorder where osseous nodules form in the reticular layer of normal skin. These nodules are formed by the deposition of lamellar bone and are characterized by osteocytes in the core and osteoclasts around the periphery. Interpretation of osteoma cutis cases has always been challenging especially using conventional two-dimensional (2D) radiographs, owing to difficulty in localization. Cone beam CT (CBCT), with its three-dimensional (3D) capabilities, offers a great tool to help detect and diagnose these calcific entities. We report a case of miliary type OC incidentally detected in the maxillofacial region using CBCT imaging.

The purpose of this article is to present the case of maxillofacial trauma patient with maxillary sinus fracture diagnosed with cone-beam computed tomography (CBCT) and to explore the applications of this technique in evaluating the maxillofacial region. A 23-year-old male patient attempted to our clinic who had an injury at midface with complaints of swelling, numbness. The patient was examined before in emergency center but any diagnosis was made about the maxillofacial trauma. The patient re-examined clinically and radiographically. A fracture on the frontal wall of maxillary sinus is determined with the aid of CBCT. The patient consulted with the department of maxillofacial surgery and it is decided that any surgical treatment was not necessary. The emerging technique CBCT would not be the primary choice of imaging maxillofacial trauma. Nevertheless, when advantages considered this imaging procedure could be the modality of choice according to the case.

Objective The purpose of this study was to investigate the value of cone beam computed tomography (CBCT) scanners versus plain radiography for detection and classification of fractures of the wrist and hand after acute trauma. Methods Images of 56 patients that received both plain radiography and CBCT after presenting to our emergency department with suspected fracture of the wrist or hand between November 2015 and July 2016 were analyzed retrospectively by three blinded observers. Results Using plain radiographs compared to CBCT, 69% of fractures of the carpals and 37% of fractures of metacarpals and phalanges remained undetected. Higher fracture classification reliability in radius fractures was observed when using CBCT. Conclusion CBCT is superior to plain radiography in detecting wrist and hand fractures in an emergency setting and presents an alternative first line imaging tool in the acute trauma patient population.

The aim of the present study was the determine the location of the mental foramen and accessories, their relationships with the alveolar and basal rims found in Peruvians adults. A descriptive, transverse and retrospective study was carried out. The sample was composed of 100 cone beam CT scans of patients, between the ages of 20 to 55 years of age, these patients were attended at the clinic of the Faculty of Dentistry of Mayor National University of San Marcos UNMSM. Were considered tomograms of mandibular dentate patients taken during 2015, classified according to age and sex, identifying in them the location of the mental foramen and accesories in relation to a lower tooth, according to the classification of Al Jasser- Nwoku.The distance of the mental foramen on the left side to the alveolar ridge had an average of 12.62 mm and on the right side it had a mean of 12.90 mm and the distance from the mandibular ridge on the left side showed an average of 14.14 mm and on the right side was 13.91 mm. The relationship of the mental foramen to the teeth was located below the second mandibular premolar. The 14% presented accessory hole, predominating position 4 (at the level of the second premolar).
