Abstract

|
|
Malignant tumors of the ear are relatively rare, of which majority occurring in the external auditory canal extend to middle ear or mastoid cavity. But in advanced cases the site of origin is often obscure. Prognosis is poor because of delay in diagnosis, limited therapeutic procedure, and difficulty of access to this region for evaluation and treatment.
Authors experienced 5 cases of malignant tumor of the ear from March 1986 to May 1989.. The following results were obtained. . 1) The incidence was 5 cases (0.002%) among 2700 outpatients with otologic disease. 2) The ratio of male and female was 4: 1.
3) The ratio of right and left site was 4: 1.
4) Average age was 51 yrs with a range 9 to 65 yrs of age.
5) The mean duration from onset of symptom to first examination was 21.4 months with a range of 2 months to 3 years.
6) Histopathologically, squamous cell carcinoma was 3 cases, adenocarcinoma was 1 case, rhabdomyosarcoma was 1 case.
7) The commonest presenting symptoms were bloody or purulent otorrhea and otalgia, and
others were deafness, facial nerve paralysis, vertigo and postauricular fistula.
8) 4 cases were treated by operation followed by radiation with or without chemotherapy
and 1 case was treated by radiation alone.
