RESUMEN
There is a paucity of information regarding the use of cochlear implants within large populations. This article describes correlates of cochlear implantation procedures using a statewide hospital discharge database. Among the 146 implant procedures, 55% involved female patients, whereas the largest groups of patients were represented by younger and older persons (27% between ages 2 and 9 years and 24% 60 years and older). A bimodal distribution was apparent for average annual age-specific rates of cochlear implantation, with the highest rates among persons aged 2 to 9 years (5.4 implants per 1 million) and persons aged 60 to 69 years (3.7 implants per 1 million). Total hospital charges, excluding professional fees, exceeded $12,000 per implant and were found to vary significantly when examined by length of stay and by calendar year of procedure. The data presented are unique with regard to the total number of cochlear implant procedures included and the large, diverse population used. This study expands knowledge concerning the epidemiology and utilization of cochlear implantation.

Audiometric findings of 2405 stapedectomized individuals were subjected to computer analysis. Results are reported in yearly intervals for six years postoperatively. Air and bone conduction thresholds were significantly improved and showed excellent stability over the period of investigation. The high success rate and sustained improvement affirms the use of the Teflon wire piston as the prosthesis of choice for stapedectomy procedure.

An optical reader system used in conjunction with a CDC 6400 computer was utilized to obtain data summaries related to the stapedectomy procedure. Medical and audiological data of 2405 cases undergoing surgery for otosclerosis were analyzed. Results are reported in tabular, figurative and descriptive forms.
