In order to improve on any existing facility, periodic audit evaluation is paramount. In this way proper and relevant service delivery can be achieved. Objective: To evaluate the range and volume of dental and cranio-maxillofacial diagnostic radiographic services offered at the University of Nairobi Dental Hospital (UNDH) in Kenya over a 5-year period (2006-2010). Methods: Retro-spective survey involving manual examination of patient records at the Division of Dental and cra-nio-maxillofacial Radiology registry of the UNDH. Results: Over the study period, the range of diagnostic radiographic services offered comprised of both intra- and extra- oral examinations. The total volume of radiographs taken was 48,874 among which 41,980 (86%) were intraoral and 6894 (14%) extraoral views. Among the intraoral views, 74% were bitewing, 25% periapical and only 1% were occlusal diagnostic views. The majority (95%) of the extraoral projections consisted of panoramic views and only 5% constituted other techniques. The volume of radiographs was high from January to September while November and December had the lowest number of examination requests. Conclusion: Intraoral radiography was the commonest examination with bitewings having been the majority while the panoramic tomography was the commonest extraoral examination performed.展开更多

Nevertheless, the regional practice patterns are highly influenced by availability, affordability and accessibility of imaging services as well as competence in interpreting radiological images and the practice of defensive medicine. The aim was to assess the use of maxillofacial trauma imaging modalities as well as to document patterns of skeletal injuries at selected government-sponsored health facilities in Kenya. Material and Methods: A cross sectional study, done in three health facilities. Results: There were 137 (81.5%) males and 31 (18.5%) females with a mean of 27.73 ± 9.86 years. Commonest aetiology of trauma was interpersonal violence (80, 47.62%) and road traffic crashes (63, 37.50%). The total number of radiological examinations was 250 with a mean of 1.49 ± 0.99 examinations per patient. Plain film radiographs were more (210, 84%) than computed tomographic scans (39, 15.6%). Dental panoramic technique was the most (104, 61.9%) popular. Most participants experienced isolated fractures to the mandible (99, 58.9%) and midface (28, 16.7%). Conclusion: Dental panoramic radiography remained the imaging of choice for mandibular fractures which had the commonest occurrence. There is a shift from the traditional conventional skull radiography to computed tomography in the diagnosis of midfacial fractures. Judicious utilization and prompt provision of affordable services in dental panoramic and computed tomographic scanning at the study centers and other upcoming health facilities are paramount in ensuring timely diagnosis and management of maxillofacial injuries in Kenya.展开更多
