11. A Selective Type of Thoracoplastic Operation.

William A. Hudson, Detroit, Michigan.

Abst. Since 1933 a type of thoracoplasty has been used which is characterized by anterior resection of the greater parts of the first two ribs freeing of the pleural attachments along the anterior mediastinum and vertebral gutter at the first stage, and a posterior resection at the subsequent stage or stages.

12. The End Results in Approximately 500 Thoracoplasty Patients.

E. J. O'brien, Detroit, Michigan.

13. Extrafascial Air as an Adjunct to Thoracoplasty with Extrafascial Apicolysis.

T. B. Aycock and (by invitation) Otto C. Brantigan

and Hugh Welch, Baltimore, Maryland.

Abst. In our hands extensive rib resection was not sufficient to close many large cavities or to afford adequate rest to many cases of diseased lung tissue. Following the employment of the "Semb Procedure" we were greatly encouraged with the immediate results but somewhat disappointed with finding months later that the regeneration of ribs had taken place convexly at a higher level than earlier plates gave promise. To offset this we began to introduce air into the extrapleural space in sufficient amount to hold the periosteum, extrapleural fascia and lung down in its position of first collapse, until rib regeneration took place in a concave manner. We feel that in a very few instances the necessity for a second operation is avoided, and in many instances the second operation may be delayed for an indefinite period without fear of regeneration interfering with the second stage collapse.

14. Planography (Body Section Radiography) as Applied Especially to Pulmonary Disease.

Warren C. Breidenbach, Dayton, Ohio (by invitation).

Abst. Brief historical review and outline of principles involved with description of types of apparatus used. There will be a presentation of illustrative cases and evaluation of the procedure from the standpoint of the internist.

15. Four Years Experience with Extrapleural Pneumo-Oleothorax.

Oscar S. Proctor, Seattle, Washington.

Abst. A summary of the principles of the procedure is given together with a discussion of the indications, technic, dangers, normal course, complications, and results based on an experience of four years with some thirty cases.
