Deformity of the forehead and face. The prognosis is grave, in consequence of the difficulty of exploring the depth of these cavities and of the possible nature of the tumour. Nevertheless, in the case of simple myxomata permanent recovery usually follows extirpation. Treatment is confined to extirpation, which is quite possible in the case of pedunculated tumours; in the case of sessile tumours free trepanation of the roof of the nasal cavities becomes necessary. The operation is quite safe. PURULENT COLLECTIONS IN THE NASAL SINUSES. NASAL GLEET. From the clinical point of view two varieties of this condition may be distinguished—inflammation of the mucous membrane of the maxillary.
