Abstract
The authors reviewed the changes in operative treatments of otolaryngological diseases from the data at the Aoto Hospital, The Jikei University School of Medicine.
On average, 500 to 600 otolaryngological operations were performed in one year in the hospital during the period.
Radical operation of the paranasal sinuses for chronic sinusitis made up about 80% of the total operations, while 90% consisted of nasal surgery each year during the period from 1949 to 1985.
The number of conservative sinus operations increased after 1960 and comprised 45% of all nasal operations during the period from 1969 to 1979.
The number of radical sinus operations is on the decrease and was responsible for 50% of the total for the same period.
The changes in operative treatments are also seen in ear surgery. Radical mastoidectomy, which had comprised 70% of all the ear surgery during the period from 1949 to 1958, decreased to 10 to 20%, while tympanoplasty operations increased to 90% after 1956.
The numbers of laryngomicrosurgery and middle ear intubation have increased during the past several years.
