[Operative approach to the retromaxillary space]

From 1977-1982 we observed 59 tumours involving the retromaxillary fossa. The primary site, direction of spread and histology are described. In selecting one of the various approaches to this anatomical region it is necessary to distinguish between tumours which have invaded the retromaxillary fossa secondarily and those which have developed primarily within it. The importance of the transfacial premaxillary approach for the latter group is shown.
