A total of ten cases of neurilemmoma were encountered during the last several years at the department of otolaryngology at Jikei University School of Medicine and its affiliated hospitals. They were two cases of neurilemmoma of the ear, two cases of the nose or paranasal sinuses, three cases of the pharynx, two cases of the cervical region, and one of the face. The number of the cases of neurilimmoma reported so for in Japanese literature amounted to 88 (38 cases in male, 44 in female and 6 unknown) exclusive of acoustic neurinoma. The number of cases presented in medical meetings counted to be 107 cases (36 cases in male 58 cases in female and 13 cases unkown). The ratio of incidence among male and female was 1 to 1.38. The general notion that neurilemmoma is a rare disease should be corrected when we see this number of incidence. The site of occurance was the tongue 40 cases, cervical region 36 cases pharynx 32 cases 36 cases larynx 27 cases, paranasal sinuses 22 cases and the middle ear 10 cases. The author discussed on the ages, symptoms, site of frequent occurence and on surgical procedures featured by 1) Preoperative neurologic examination. 2) Anatomical relations with sorounding tissue or organs. 3) preventive measures of injury to major organs. 4) Nerve anastomosis following to resection of the tumor. 5) Careful operative procedures. 6) Complete removal of the tumor with its capsule. 7) Preventive measures for bleeding.
The authors report on the results of speech audiometry performed on aircrafts in flight. Apart from routine speech audiometry, words with similar pronounciations were used in this test since pilots are required to distinguish the confusing words in receiving instructions during their flights.
A total of 54 cases with nasal allergy were treated with histaglobin. An evaluation of the efficacy of this drug revealed 68.5% of the cases fell in categories either “mildly improved” or “improved”, while only singe case was termed as “markedly improved”. Histaglobin however, was found to be equally effective in type I through type III. This drug may be used with favorable effect to those cases in which their allergens are not identified. A combined treatment by histaglobin and desensitization for type I nasal allergy seems to enhance the effect of treatment.
The authors reported a case of hemophila whose chief complaint was bleeding from the tonsils. Literature for last 15 years was reviewed for cases with hemophilia whose manifestations were in the nose and throat.
The patient was a 28 year old male, who developed following to nasal surgery exophthalmos, visual disturbance associated with pain which appeared in each eye in succession. The patient finally came to a total loss of vision. The pathological examination of the tissue removed from the orbit showed a granulous tissue. This patient incidentally developed cancer of the pituitary gland about 15 years after the surgery to the orbit. An autopsy revealed a pseudotumor remaining in the orbit. The author considered the tumor in the orbit was a pseudotumor due to a collagen disease.
The author previously reported on a use of polaroid camera in oto-laryngological field. (Oto-laryngology-Tokyo 9.2, 61, 1966). This is the second report on this subject inwhich the author reported on handy use of color films for medical photography by means of a special filter. The color pictures remained fresh and clear even in three years after they were developed.
