=Otomycosis= or fungus infection of the auditory meatus is rare. It usually resembles other infections symptomatically, but often without pus. A microscopic examination will serve to diagnose the condition. The treatment consists of thorough cleansing, drying and the free application of alcohol. Alcohol is dropped into the ear until the canal is full and a pledget of cotton applied to retain it. Usually two or three applications are sufficient to effect a cure. =Eczema= of the auricle and meatus is of two types, the squamous or scaly form and the sclerotic form. Both forms are chronic and may be readily diagnosed by the appearance. =Treatment.=—Some cases are very difficult to cure but we have had excellent results with the following treatment: Careful adjustment of cervical and mandibular lesions; thorough treatment of any local infections of head or neck; direct application of phenol-glycerine, local cleanliness and protection from irritation. Diseases of the Middle Ear Clinically the middle ear consists of the tympanic cavity and its contents, the Eustachian tube and the mastoid cells. Acute Suppurative Otitis Media Acute infections of the middle ear result from acute nasopharyngeal affections such as colds, influenza, measles, mumps, whooping cough, etc. Bathing in contaminated water often results in infection to the middle ear through the Eustachian tube. =Diagnosis.=—Earache, pain on pressure under the angle of the jaw and sudden deafness are the symptoms. (There are also the common febrile symptoms.) The chief physical signs are: redness and bulging of drum membrane, and contraction and tenderness of upper cervical muscles. =Treatment.=—If the patient is seen before the drum has ruptured it is seldom necessary to lance the drum if the proper treatment is given promptly. Drainage must be obtained and maintained by catheter aspiration through the tube irrigation of the nasopharyngeal cavity, irrigation of the meatus by means of the continuous ear irrigator and application of dry heat over the affected part. Heat is best applied by means of a therapeutic lamp. (Any lamp with reflector that will furnish proper heat is efficient as there is no virtue in colored light.) The skin surface over the ear, side of face and mastoid region is first well lubricated with some mineral oil to prevent blistering and the heat is applied either constantly or intermittently. A pledget of absorbent cotton dipped into phenol-glycerine is placed in the meatus and forced loosely against the drum. This should be removed every few hours and a fresh pledget put in. The neck and upper dorsal muscles should be kept relaxed and adjustive treatment given frequently.
