    Evaluation of the relationship between tympanic plate morphology and degenerative bone changes of condyle and articular eminence
    (Elsevier, 2021) Belgin, C. Aktuna; Serindere, G.; Aksoy, S.; Orhan, K.
    Introduction: This study aimed to evaluate the relationship between tympanic plate morphology and degeneration of temporomandibular joint (TMJ) condyle and articular eminence (AE). Material and methods: Cone beam computed tomography images of 700 patients (345 males, 355 females) were evaluated. The prevalence and location of tympanic plate pneumatization (TPP) and foramen tympanicum (FT) were recorded. Sagittal scans of the TMJs were classified according to the degenerative bone changes of condyle and AE (flattening, osteophytes, erosion, sclerosis, and subcortical cysts). Results: TPP was found in 106 of 700 patients (15.2%) while FT was found in 165 (23.2%) of the patients. TPP and FT were bilateral in 52 (49.1%) patients and 46 (27.9%) patients, respectively. The mean axial diameter of FT was 2.53 mm and the mean sagittal diameter was 2.52 mm. The most common degenerative changes for condyle and AE were flattening. Conclusion: To know these structures is important for surgical operations in the region of TMJ and ear to prevent complications. CBCT is useful to evaluate these anatomical landmarks and the relationship between them and the degenerative bone changes of condyle and AE. (C) 2020 Elsevier Masson SAS. All rights reserved.

    Prevalence of Multiple Miliary Type of Osteoma Cutis in the Maxillofacial Region as an Incidental Finding: A Retrospective Cone Beam Computed Tomography Study
    (University of the West Indies, 2024) Gunduz, K.; Serindere, G.; Avsever, H.; Orhan, K.
    Objective: Miliary osteoma cutis (MOC) is a rare variant of osteoma cutis in which multiple fragments of bone formations are embedded in the skin. In general, they are asymptomatic, benign and detected incidentally on radiographic examination. Methods: This prevalence study was made by using cone beam computed tomography (CBCT) scans. A total of893 CBCTscans were evaluated. A total of202 ofthem were excludedbecause of poor diagnostic quality. The occurrence frequency of incidentally found multiple miliary type of osteoma cutis in head and neck area was noted. Median and range were used to describe the age of the patients. Results: A total of691 CBCT images were screened. Ofthese, 268 (38.8%) werefrom female patients and 423 (61.2%) were from male patients. The median age ofpatients referredfor CBCTwas 45.0 (IQR=30.0) years andwithin the age range of5-84 years. A total of22 (3.2%) multiple MOC cases in the maxillofacial region were discovered on 691 patients’CBCTscans. Conclusion: Calcified lesions in the head and neck region were commonly seen in CBCT -mages. Although most of-he calcifications are asymptomatic and require no treatment, diagnosis should be carefully made to avoid unnecessary further diagnostic assessments. It will also provide the ability to comprehensively evaluate underlying diseases. © 2024 University of the West Indies. All rights reserved.
