[Middle ear carcinoma].

Middle-ear cancer represents 5 to 10% of all ear neoplasms. Risk factors include chronic suppurative pathology of the middle ear and prior irradiation. Most malignant tumors are squamous-cell carcinomas. We report the case of a 51-year-old woman with this process. The ideal treatment is mastoidectomy or pterosectomy followed by radiotherapy. We made a bibliographic review of the clinical manifestations, diagnosis, treatment, and prognosis of middle-ear cancer. Five-year survival rates range from 25 to 50% in patients who undergo surgery and radiotherapy.

[Olfactory esthesioneuroblastoma. Review of seven cases].

Esthesioneuroblastomas are fairly rare malignant tumors: only 20 cases have been reported in Spanish records. It is locally aggressive and produces late recurrences. There is no such thing as a universally accepted treatment model. We describe our experience with 7 cases seen in our hospital from 1980 to 1996. A or B stages can be treated with irradiation, surgery or a combination of both. C stages with the most aggressive tendencies may require the combined use of preoperative irradiation, surgery and chemotherapy. We analyzed the forms of presentation, diagnosis, differential diagnosis, treatment, prognosis, and survival. The 5-year survival rate was 75, 60 and 41% for stages A, B and C, respectively.

[ENT outpatient surgery].

The number of patients who undergo outpatient surgery is constantly growing in Spain. Outpatient surgery is interesting not only because of its economy, but also the social benefits that derive from patients returning home sooner and the rapid reduction of the waiting list. We discuss our experience in the last year with 40 patients who underwent surgery. We made a comparative study of patients with the same pathology and anesthetic risk who were treated by outpatient surgery and those treated by inpatient surgery with a traditional technique who were admitted 24 hours before surgery. Our rate of complications (19%) was close to the traditional rate. However, 3, 927, 000 pesetas were saved and the patients were very satisfied, which encouraged us to continue. Indications and complications are discussed.
