In patients with idiopathic sudden hearing loss, the extent of the inner ear lesion tends to correlate with the severity of cochlear damage. Vestibular assessment may be valuable in predicting the final outcome.
Cochlear implantation is generally a safe procedure. The most common complication was device failure. Although complications in this adult population were rather uncommon, some of them were serious, and an immediate intervention was necessary for a successful outcome.
A combination of vestibular evoked myogenic potential and electronystagmography testing indicated the existence of vestibular involvement in many patients with idiopathic sudden hearing loss. Both tests are necessary in order to obtain a more thorough and in-depth knowledge of the pathophysiology of idiopathic sudden hearing loss.
The results of the present study highlight the importance of well-planned interventions in order to reduce depression and increase self-efficacy in diabetic adults and to help them further improve their quality of life.
It is suggested that ovarian factors rather than exhaustion of pituitary reserves are important for termination of the endogenous LH surge during the normal menstrual cycle.
The aim of this study was to report our experience with cartilage tympanoplasty (CT) in smokers and compare it with that of non-smokers using a retrospective chart review at a tertiary referral center. Between September 2008 and September 2010, cartilage tympanoplasty was performed in 52 patients. Among them, 27 were active smokers and 25 former or non-smokers. The entire tympanic membrane was replaced with conchal cartilage, shaped either as a shield for cases with intact canal wall mastoidectomies, or crashed for cases with canal wall down procedures. The mean post-operative follow-up was 12 months (range 6-18 months). A complete pre- and post-operative audiologic evaluation was obtained in all patients. Graft take was successful in all patients. The overall average pre-operative and post-operative pure tone average air-bone gaps (PTA-ABG) was 52.2 dB ± 17.7 dB and 35.4 dB ± 17.9 dB, respectively, with an overall improvement of 16.8 dB (p < 0.001). A post-operative PTA-ABG of 25 dB or less was achieved in 39 (75 %) patients (p < 0.001). In smokers, the hearing improvement was 17.6 dB (p < 0.001) with a PTA-ABG of 25 dB or less in 19 (70 %). In non-smokers, the average hearing improvement was 16.8 dB (p < 0.0005) with a post-operative PTA-ABG of 25 dB or less in 19 (76 %), (p < 0.001). The results showed that the CT technique is a very effective procedure for smokers. Excellent graft take and satisfactory hearing results can be accomplished regardless of smoking habits.
Aim: To explore in a prospective study the evidence of certain viral and toxoplasmosis infections in sudden sensorineural hearing loss (SSHL). Methods: 84 consecutive patients with SSHL meeting certain criteria. All patients were assessed for specific IgM antibodies against cytomegalovirus, herpes simplex virus, toxoplasma and Epstein-Barr virus. All were treated with intravenous steroids and assigned to two groups: 76 IgM negative (NV group) and 8 IgM positive (no history of acute infection – V group). Results: The mean hearing level at presentation was 86.5 dB HL (median, 100) in the V group and 60.7 dB HL (median, 61) in the NV group. The difference was statistically significant (p = 0.003). The mean hearing level following treatment was 81.8 dB HL (median, 88) in the V group and 48.7 dB HL (median, 39) in the NV group. The difference was statistically significant (p = 0.004). There was a considerable improvement in hearing after treatment only in the NV group (p < 0.000001). Conclusions: Recent subclinical viral or toxoplasmosis infections may be involved in the pathogenesis of SSHL (in approx. 10% of cases), suggesting that SSHL is not a single disease. When certain viruses or toxoplasmoses are involved, the hearing is much worse in comparison to patients with no such indication of infection. An alteration in treatment dosage or method of steroid administration may be needed in such cases.
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.
