RESUMEN
BACKGROUND: The aim of this study was to evaluate the effectiveness, indications, and contraindications of the extracorporeal approach in treating a severely deviated nose. METHODS: Sixty-four patients operated on for aesthetic correction of a severely deviated nose were studied. Forty-six of them were first operations and 18 were revision cases. The surgical procedure of choice was the closed technique. Septal cartilage was prepared and then dislocated, followed by external alignment and reimplantation. Hump reduction with lateral osteotomies and, occasionally, medial dislocation of nasal bones was carried out. RESULTS: Cosmetic results were satisfactory in all first operation cases. In 11 of the 18 revision cases, septal preparation was impossible; in 2, septal sagging was observed; and in 1, perforation was noted. CONCLUSIONS: Extracorporeal septoplasty is an effective, safe, and reliable technique, especially for twisted noses undergoing surgery for the first time. However, it is strongly contraindicated in a revised deviated nose.

BACKGROUND: The long-term reliability of cochlear implants over time is an important issue for patients and cochlear implant teams. The calculation of cumulative survival rates including all hard failures of cochlear implants is suitable to report objectively about cochlear implant reliability. METHODS: This is a report of 192 cochlear implants from different manufacturers in adults (n = 58) and children (n = 134). RESULTS: The overall cumulative implant survival rate was 91.7% for a period of 11 years. The main reasons for hard failures were design errors of the products and direct or indirect trauma to the cochlea implant site (especially in children) with consecutive breaks of the implant body or electrodes. CONCLUSIONS: To improve our knowledge about reliability of cochlear implants more studies on cumulative long time survival of cochlear implants are needed, where functional failures and complications for whatever reason (design, mechanical, electronic, medical) are included. Cochlear implant reliability data should be considered during the choice of an implant for each individual patient.
