There are a few recorded cases of congenital division of the nose. Bartholinus, Borellus, and the Ephemerides speak of duplex noses. Thomas of Tours has observed congenital fissure of the nose. Rikere reports the case of an infant of three weeks who possessed a supernumerary nose on the right nasal bone near the inner canthus of the eye. It was pear-shaped, with its base down, and was the size of the natural nose of an infant of that age, and air passed through it. Hubbell, Ronaldson, and Luscha speak of congenital occlusion of the posterior nares. Smith and Jarvis record cases of congenital occlusion of the anterior nares. Anomalies in size of the mouth are not uncommon. Fournier quotes the history of a man who had a mouth so large that when he opened it all his back teeth could be seen. There is a history of a boy of seventeen who had a preternaturally-sized mouth, the transverse diameter being 6 1/2 inches. The mother claimed that the boy was born with his foot in his mouth and to this fact attributed his deformity. The negro races are noted for their large mouths and thick lips. A negro called "Black Diamond," recently exhibited in Philadelphia, could put both his fists in his mouth. Morgan reports two cases of congenital macrostoma accompanied by malformation of the auricles and by auricular appendages. Van Duyse mentions congenital macrostoma with preauricular tumors and a dermoid of the eye. Macrostoma is sometimes produced by lateral fissures. In other cases this malformation is unilateral and the fissure ascends, in which instance the fissure may be accompanied by a fistula of the duct of Stensen. Sometimes there is associated with these anomalies curious terminations of the salivary ducts, either through the cheek by means of a fistula or on the anterior part of the neck. Microstoma.--There are a few cases on record in which the mouth has been so small or ill-defined as not to admit of alimentation. Molliere knew an individual of forty whose mouth was the exact size of a ten-centime piece. Buchnerus records a case of congenital atresia of the mouth. Cayley, Smith, Sourrouille, and Stankiewiez of Warsaw discuss atresia of the mouth. Cancrum oris, scarlet fever, burns, scurvy, etc., are occasional causes that have been mentioned, the atresia in these instances taking place at any time of life.
