ABSTRACT
A total of 20 stapedotomy and 24 stapedectomy cases were retrospectively reviewed to establish the causes of failure, and to evaluate hearing results after revision surgery. Our series included 23 male and 21 female patients. Mean age at revision time was 42 years, and the mean interval from primary surgery and revision stapes surgery was 27 months. The retrospective review of our data, revealed that the most common cause for revision surgery was a displaced prosthesis (47.7%). After revision surgery, the mean post-operative air-bone gap was 14.78 dB. A mean post-operative air-bone gap within 10 dB occurred in 24 patients (54.5%), in 14 patients (31.5%) this was between 11 and 20 dB, in 5 patients (11.5%) between 21 and 30 dB, and in one patient (2.5%) > 30 dB. There were no "dead ears" in this series. Our results compare to other reported series, and confirm that after revision stape surgery, an air-bone gap closure within 10 dB is difficult to obtain. In the present series, the use of the total ossicular replacement prosthesis resulted in the poorest functional hearing results.

Secondary neoplasms of the larynx are rare and account for 0.09 to 0.4% of all laryngeal tumors. These tumors can occur by hematogenous or lymphogenous spread and may represent a diagnostic dilemma when the laryngeal localization is the only manifestation of disease. When multiple metastases are present, the appropriate treatment becomes even more controversial. To our knowledge only 148 cases of metastatic laryngeal neoplasms have been reported in the literature, with cutaneous melanomas and carcinomas from the kidney representing the most frequent primary sites of origin. Our research of the available literature has shown that only nine cases of metastases from colon adenocarcinomas have been described. In general, the overall prognosis of patients with a secondary laryngeal tumor is poor, since involvement of the larynx by a distant tumor commonly occurs in the terminal phase of the primary disease process. As such, the aim of treatment frequently is only to improve the quality of life of the patient. We report a case of colon adenocarcinoma metastatic to the larynx and discuss the problems related to its pathogenesis, diagnosis and treatment.
