Not without interest is a case of disease of Highmore’s antrum, originating in the following way. A charlatan attempted to extract by means of a common key a canine tooth which had erupted in an abnormal position. He applied the hollow of the key to the tooth and beat upon the handle with a stone. But the tooth, instead of penetrating into the hollow of the key, was driven into the maxillary sinus.[441] Two important cases of “stony excrescence” of the gums (probably osteomas) are to be found in Chapter XXXII. One of these tumors was removed by the dentist Carmeline after the patient had been tortured with useless operations by surgeons, who, not recognizing the true seat of the evil and mistaking it for a tumor in the cheek, had, over and above all the rest, produced a permanent disfigurement of the patient’s face and a perforation of the cheek that he was obliged to keep closed for the remainder of his life with a wax plug, to prevent the exit of the saliva and of liquid or masticated aliments.[442] Several important observations on obstinate cases of cephalalgia, prosopalgia, otalgia, and other varieties of pain arising from dental caries are to be found in Chapter XXXIII. In all these cases the removal of the decayed tooth or teeth procured the prompt cessation of pain. Among others worthy of note is a case of violent otalgia caused by the decay of a lower molar, which, however, was itself not painful. This circumstance drew Fauchard himself into error, causing him to believe that the otalgia was independent of the decayed tooth; he therefore merely stopped the tooth to prevent the caries from extending farther. The pain in the ear continued, however, and the patient therefore consulted a doctor of the Faculty of Paris, Coutier, who told her that the decayed tooth might be the cause of the earache, and that, therefore, before undertaking any other cure, she ought to have it extracted. This advice was followed and the earache ceased promptly and completely.[443]
