[Clinical aspects, evaluation and treatment of odontogenic myxomas (fibromyxomas)]

Myxomata are benign, locally invasive, growing tumours which presumably arise from the connective tissue of dental papillae. They grow slowly and do not give rise to any symptoms. They are therefore of considerable diagnostic importance. They arise in the dentigerous part of the jaws and extend into the ramus of the mandible and from the maxilla into the maxillary sinus. X-ray shows them as mono- or polycystic spaces. The benign nature of myxomata leads to the temptation to operate conservatively. Excochleation and curettage have a recurrence rate of about 25%. Further excision is therefore required which, depending on the extent of the tumours, consists of partial resection of upper or lower jaw. Personal experience of 10 patients is given and discussed.
