    Odontogenic myxoma: a clinicopathological study in a South African population
    (Blackwell, 2016) Titinchi, Fadi; Hassan, Bassam A.; Morkel, Jean A.; Nortje, Christoffel
    Background: Odontogenic myxoma is a benign, locally aggressive neoplasm of the jaws. Prevalence rates range between 0.5% and 17.7% of odontogenic tumours. There are few reports in the literature on this lesion in African populations, and therefore, this study aimed to report on odontogenic myxoma in a South African population over a 40-year period. Methods: The clinical records and orthopantomograms of 29 histopathologically diagnosed odontogenic myxoma were retrospectively analysed. Details of age, gender, ethnic origin and clinical, histological as well as radiological features were recorded. Results: The ages of patients ranged from 7 to 44 years with a mean of 21.3 years. The male-to-female ratio was 1:2.6 with the majority of patients being of mixed race and Africans. Clinically, 31% complained of pain while 58.6% had a history of swelling. The majority of odongenic myxomas (62.1%) were located in the mandible with the posterior region being most commonly affected. Multilocular lesions (69.2%) were more common and were significantly larger than unilocular lesions (P < 0.05). The outline of these tumours was mostly well-defined (84.6%) with different degrees of cortication. Only one tumour caused tooth resorption, while 20 cases (76.9%) caused tooth displacement. Six tumours expanded into the maxillary sinus, and 14 tumours caused expansion of the mandible. Conclusions: Odontogenic myxomas have variable clinical, radiological and histological features. Most of these features in this population were similar to other populations. It is mandatory to use conventional radiographs along with histopathological examination to aid in arriving at an accurate diagnosis.

    Residual cyst of the jaws: A clinico-pathologic study of this seemingly inconspicuous lesion
    (Public Library of Science, 2020) Titinchi, Fadi; Morkel, Jean A.
    Residual cysts are relatively rare inflammatory cysts of the jaws. They are essentially radicular cysts without the presence of the offending dentition. These lesions have the ability to destroy bone within the jaws without any symptoms. Moreover, they can mimic more aggressive cysts and tumours on radiographs. The aim of this study was to describe the clinico-pathological features of residual cysts in order to discern them from other cystic lesions as well as analyse their management and recurrence patterns.

    Substance abuse and maxillofacial injuries
    (South African Dental Association, 2014) Ranchod, S.; Smit, Dirk A.; Morkel, Jean A.
    Some of the major causes of maxillofacial injuries are assault/ inter-personal violence (IPV), motor vehicle accidents (MVAs), work-related injuries, sporting accidents and falls. However, the epidemiological data for the different types of injury vary significantly and are influenced by geographic location, socioeconomic status, the time of year when patients are assessed and the type of facility where the study is conducted. The 2012 Statistics South Africa's release document on 'mortality and causes of death in South Africa' indicated that 9.8% of all deaths in South Africa were reported as nonnatural. Transport accidents were the third most common (11.2%) reported cause of non-natural deaths followed by assaults at 10.2%. According to a number of international studies, the face is the most common site affected by assault- related trauma. Substance abuse is a major public health concern in South Africa and has also been rated as the leading health problem in the United States. Intoxication is also the most common denominator associated with violence and injury. In a Swiss study, Eggensperger found that almost a quarter of assault-related facial fractures were caused by people intoxicated with alcohol, illicit drugs or a combination thereof. This article explores epidemiologic data and relevant information related to maxillofacial trauma, specifically associated with alcohol and substance abuse.
