Background:
Correction of secondary nasal deformities frequently requires cartilage to build the framework of the nose. Traditionally, autologous costal cartilage has been used because of the paucity of the septal cartilage. Because of associated donor-site complications and increased operating time, irradiated allografts have been used. These grafts have a higher rate of resorption and infection. Thus, the authors have used fresh frozen, nonirradiated, cadaveric rib cartilage as donor cartilage to avoid these shortcomings, and they present their early experience.
Methods:
The operative data of 50 patients who underwent secondary rhinoplasty performed by the senior author between 2014 and 2017 were analyzed. The outcomes of the rhinoplasty were evaluated by preoperative and postoperative photographs by four blinded plastic surgeons, and the results were tabulated using the Independent Rhinoplasty Outcome Score.
Results:
Fifty patients were followed up over an average period of 3.35 months (range, 1 to 18 months). There was only one complication (infection, 2 percent), which did not need revision surgery. There was no warping or extrusion in this cohort.
Conclusions:
The authors believe that fresh frozen, nonirradiated cartilage allografts are an evolving source of donor cartilage grafts for revision rhinoplasty because they are associated with lower complication rates. However, further long-term studies with an increased sample size are necessary to prove that fresh frozen cartilage grafts are better than other sources.

Therapeutic, IV.
Background: The occurrence of hearing loss in the course of chronic renal failure (CRF) was investigated in numerous research studies, attempting to explain both the etiological factors and treatment possibilities. According to various authors, the percentage of occurrence of hearing loss in patients suffering from CRF differs between 20% and 80%.Objectives: Our study was conducted in this context as an attempt to find the prevalence of sensorineural hearing loss in chronic renal failure patients, to assess the frequency and type of hearing loss in patients with CRF, to find any correlation between duration of illness and SNHL and also to assess the etiological factors related to sensorineural hearing loss among chronic renal failure patients.Methodology:This is a hospital based cross-sectional study conducted at Dr S.M.C.S.I. Medical college, Karakonam, during the period November 2013 -June 2015. A sample of 89 chronic renal failure patients were assessed by pure-tone audiogram.Results: Out of the 89 chronic renal failure patients, 57 patients (64%) were detected to have sensorineural hearing loss in the order of frequency high>mid>low frequency. In this study, there is a statistically significant correlation between age of the patients and stage of the disease with SNHL. However there is no significant correlation between duration of chronic renal failure and blood parameters with SNHL.Conclusion: SNHL is common among patients with chronic renal failure. Hence a pure tone audiometry should be done routinely in all chronic renal failure patients even if they don't report hearing loss. Moreover periodic audiological assessment should be incorporated in their management to start rehabilitation as early as possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
