Venous angiodysplasias with endoral manifestation. The problems of therapy

: Five oral venous angiodysplasia cases are presented by the authors. Besides subjective aesthetic and psychological factors, the treatment of these lesions depends on objective chewing problems and on haemorrhagic risk. This can be either spontaneous or in relation with dental surgery during teeth extraction or third molar pathology therapy. In two patients the lesions affected the tongue and cheek mucosa including the submandibular and masseter region. In one patient there was just one localization at the tongue apex. In another patient the lesion affected only the cheek mucosa and in another the cheek was affected in all its thickness at the left hemimandibular level. Three patients were treated surgically, another with sclerotherapy and another one didn't undergo any treatment, as the lesion didn't present any haemorrhagic risk and the symptomatology was only related to salivary lithiasis. During a three year follow up the patients surgically treated recovered completely, the patient treated with sclerotherapy showed a progressive reduction of the swellings ending in an almost complete recovery. The clinical experience and the literature review show that the correct oral venous angiodysplasia diagnosis and a right sclerotherapy or operation, preventive if necessary, nearly always allow dental surgery in the time required for the ongoing dental pathology.
