The authors have experienced 31 cases(male 20, female 11) of ear cancers during last 10 years(1970-1979) at the Dept. of Otolaryngology, Cancer Research Hospital. These ear cancers were diagnosed by the tissue biopsy and tried to treat with
CO60 irradiation. The authors report on this clinical and statistical study with literature review and the following results were obtained. 1) The peak incidence of age distribution was 40 to 60(54.8%), also, found in childhood. 2) There were 20 males and 11 remales with sex ratio 1.7 : 1. 3) The mean age was 39.7 in male, 47 in female and 42.3 in total. 4) The most frequently encountered ear cancers were found in the mastoid and temporal region 33.3% and then the external auditory canal 27.3%, middle ear 18.2%, auricle 15.2%, retroauricular region 6%. 5) The chief complaints and presenting symptoms were as followings; aural growth 41.9%, bloody otorrhea 41.9%, deep continuous pain 38.7%, facial paralysis 29%, hearing loss 9.7%, vertigo 9.7%. 6) The mean symptomatic duration prior to the first visit to the hospital was 1-6 months, as we could see externaly and 2-4 years couldn't see. 7) The mastoid x-ray findings were as followings: loss of mastoid air cells 93.5%, loss of mastoid air cells with surrounding bony destruction 83.9%. 8) Histopathologically the squamous cell carcinoma 67.7%, adenocarcinoma 9.7%, basal cell carcinoma 9.7%, sarcoma 6.45%, malignant papilloma 6.45%. Histopathological distribution of the ear cancers by regions was as followings: squamous cell carcinoma found in all region of the ear, adenocarcinoma in external auditory canal and middle ear, basal cell carcinoma in exernal auditory canal and auricle, sarcoma in external auditory canal and mastoid temporal region, and papilloma in middle ear and retroauricular region. 9) The regional lymph node metastasis was seen 12.9%, distant metastasis 6.5%. 10) Probably, prognosis is not so good.
