RESUMO
Oral cancer is usually preceded by oral potentially malignant disorders (OPMDs) and early detection can downstage the disease. The majority of OPMDs are asymptomatic in early stages and can be detected on routine oral examination. Though only a proportion of OPMDs may transform to oral squamous cell carcinoma (OSCC), they may serve as a surrogate clinical lesion to identify individuals at risk of developing OSCC. Currently, there is a scarcity of scientific evidence on specific interventions and management of OPMDs and there is no consensus regarding their management. A consensus meeting with a panel of experts was convened to frame guidelines for clinical practices and recommendations for management strategies for OPMDs. A review of literature from medical databases was conducted to provide the best possible evidence and provide recommendations in management of OPMDs
RESUMO
Progassive hemifacial atrophy is an uncommon and poorly understood degenerative condition characterized by atrophic changes involving the entire one side of the face, head and associated structures and typically appearing during the growth spurts to young adulthood. The condition involves both soft tissues and bone of the affected side. Intraorally the tongue, lips and salivary glands may be involved. Developing teeth may also show incomplete root development deleyed eruption. The couse of the condition is obscure or unknown although speculation has considered trophic malfunction of the cervical sympathetic nervous system, a history of prior trauma has been documented in some cases, although other reports have considered a viral or borrelial infection. It is usualy sporadic but a few familial cases have been reported suggetsting a possible hereditary influence and many investigators believe it to be a localized from of scleroderma. Five cases of Hemifacial Atrophy (Parry Romberg Syndrom) has been reported and discused.
