Regulations from the Occupational Safety and Health Administration require the performance of audiometric tests on workers exposed to potentially hazardous noise levels. These tests are frequently performed by Occupational Hearing Conservationists who have taken a 20-hour course based on recommendations of the Council for Accreditation in Occupational Hearing Conservation. Unless audiograms performed by such personnel are promptly reviewed and appropriate referral to specialists made, significant and potentially life-threatening otic disease may go undetected. This paper reports a series of workers with acoustic tumors initially detected by an Occupational Hearing Conservation Program. It is dangerous to assume that the hearing loss and tinnitus reported by noise-exposed workers is necessarily the result of workplace noise exposure.

The roentgen findings of a rare benign chondroma of the petrous apex are presented. This patient's clinical history made it imperative that we rule out a metastatic breast lesion. A transcochlear approach verified the benign nature of this lesion

The admission MMPI profiles of approximately half of 337 male alcoholics treated at the Hazelden Foundation (Center City, Minnesota) were classifiable into four groups: neurotic, classic alcoholic, psychopathic, and psychotic. The discharge MMPI profiles of the neurotic, classic, and psychotic types showed foreshortening but maintained their basic configurations. The psychopathic type's discharge MMPI profile showed no major change either in elevation or shape. Several biodemographic and treatment outcome differences were found among the four profile types.

Bilateral lesions which appeared clinically to be branchial cleft sinuses were removed from a patient's neck. One was indeed a branchial cleft sinus, with elements of salivary tissue, but the other proved to be pure salivary tissue with a duct characteristic of a salivary gland. The embryology and clinical characteristics of heterotopic salivary glands are discussed. The occurrence of a heterotopic gland together with a branchial cleft sinus supports the contention that the heterotopic glands arise through errors of development in the branchial apparatus

The specific contribution of admittance procedures in the diagnosis of hearing impairment was studied in a group of 53 handicapped children. The value of admittance procedures was assessed in relation to that of otoscopy and pure tone audiometry. Admittance procedures and otoscopy were successfully performed in all but one of the children and indicated conductive pathology in about 40% of the subjects, whereas pure tone audiometry was not feasible or inconclusive in 30.2% of the subjects. In 5.7% of the subjects admittance procedures proved the only diagnostic tool.

An unusual recurring mass presented in the parotid region in a young woman. The presentation of the mass was unusual in that it varied with the positioning of the patient's head and with exertional and emotional activity. Prior surgical attempts at cure were unsuccessful. Biplanar subtraction radiographic techniques were used to pinpoint the anatomical problems. This lesion is a vascular anomaly, which requires specific attention to its morphology in order to effect a permanent cure. This case of parotid venous ectasia with its unusual symptom complex was successfully treated, and more than four years have passed without recurrence.

Seven of the 7000 patients who underwent cardiopulmonary bypass at Bellevue and University Hospitals between 1969 and 1978 developed sudden loss of hearing in one ear immediately after surgery. Four of the seven patients showed subsequent improvement in hearing but none recovered completely. None had vertigo. All were male. The most likely cause is particulate microemboli generated by cardiopulmonary bypass
