Brainstem evoked response audiometry is useful in the identification of threshold levels as well as in the diagnosis of eighth nerve tumors. The instrumentation is a modification of the electroencephalograph and an averaging computer; 3,000 clicks, 16/s, are presented and averaged for each printed response. Evoked responses can be obtained from a patient who is unable or unwilling to respond to conventional behavioral testing; best results are obtained from quiet or asleep patients.

Blunt chest trauma with tracheobronchial rupture.

The unusual complex of physiological problems associated with rupture of the tracheobronchial tree complicating blunt chest trauma is discussed. The mechanics of injury leading to rupture are abrupt compression of the chest with consequent fixation of the cervical trachea where it enters the mediastinum, separation of the lungs, and fracture of the bronchus over the vertebral bodies. Treatment by aspiration thoracentesis, tracheotomy, and thoracotomy with primary repair as well as expectant therapy are discussed. Two cases, one treated expectantly and one treated by thoracotomy, both with complete recovery, are presented.

Tonsillectomy and adenoidectomy: incidence and mortality, 1968--1972.

To determine the number of tonsillectomies and adenoidectomies (T-As) from 1968 to 1972 and their associated morbidity and mortality rates, a questionnaire was sent to all the hospitals listed in the Directory of the American Hospital Association (6,759). The data were analyzed and statistical projections were made. An analysis was also made of the summary report of the "Study on Surgical Services for the United States," with regard to the incidence of T-A was also made. The results are presented in the following report.

Nasopharyngeal irradiation treatment of hyperplastic adenoids.

Radiotherapy treatment in childhood is an important cause of thyroid cancer. In the 1930 to 1950 era, radium irradiation of the nasopharynx was used to control hyperplastic adenoids. Because of the technical characteristics of this applicator, sufficient radiation was not applied to the thyroid by this technique to stimulate the development of thyroid malignancies. No malignancies have been reported thus far as a result of this treatment.
