One-hundred and thirty four myringoplasties were performed during the last five years by the author. The prodedures employed could be divided into six different techniqes which were 1. total replacement of the tympanic membrane 2. partial closure 3. Shea's technique 4. Swing door plasty by Palva 5. Closure of epitympanic perforation 6. Sheehy's technique. The closure of the tympanic membrane may be attained by any of the above procedures but the author recommended to avoid total replacement since it tended to result in functionalfailure. Myringoplasty is contraindicated for cholesteatoma of the epitympanium, even if without actual infection. The techniques No.2 through No.6 except No.5 were found to be excellent but cases should be selected carefully based upon the size and location of the perforation, pathology of the middle ear, hearing threshold of the other ear and the ages of the patients.
Mucosus otitis media or otitis media caused by pneumococcus Type III was one type of otitis media that was notorious to pre-war otolaryngologists in Japan. In spite of acute infection of the middle ear it acutally is, the manifestations are more like of chronic character featured by pale tympanic membranes, less pains associated with low grade fever. The hearing loss due to the disease is often severe, and the complication sometimes ensue abscess in the cervical region, intracranial infections and even septicemia. Surgical intervation was often the treatment of choice for prevention of the above complications. The incidence of mucosus otitis was considered exteremely rare after the advents and avairability of various antibiotics, however, the author encountered five cases of mucosus otitis media in the past year and feared that this type of otitis media might increase in years to come as resistive organisms would develop over the abuse of antibiotics.
