Functional results of 394 bilateral stapedotomies evaluated with the Glasgow Benefit Plot

Abstract

This study aimed to evaluate the results of 394 bilateral stapedotomies according to the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guidelines and with the Glasgow Benefit Plot (GBP) and also analyze the benefit of a second-ear stapedotomy in achievement of normal and symmetrical hearing using retrospective chart review. The charts of 1,369 stapedotomies performed by senior author (J.H.) from 1991 to 2006 were reviewed. Results of 394 bilateral stapedotomies were included. The hearing results were evaluated according to the 1995 AAO-HNS Committee on Hearing and Equilibrium (CHE) guidelines and the GBP criteria. Success rates after the first and second ear surgeries were separately analysed. ABG closure < or =20 dB was demonstrated in 98% of cases after both first and second procedures. Postoperative AC gain was higher in the first ear surgery compared with the second ear surgery in all groups of preoperative hearing impairment. As a result of first ear surgery, 142 (72%) patients changed into the category of unilateral hearing loss. As a result of second ear surgery, 125 (64%) patients changed into the category of normal and symmetric hearing. In this study the largest group of 394 primary bilateral stapedotomies was simultaneously evaluated according to AAO-HNS guidelines and GBP criteria. The results showed that the first ear surgery was more successful in achievement of normal hearing in the operated ear. Second ear surgery was more beneficial in providing symmetric hearing.

Minimally Invasive Surgery for the Treatment of Hyperacusis

“…While the second ear surgery does not show a significant increase in ULL, the participants’ subjective statements substantiate the benefit of second ear surgery. Similar phenomena where greatest benefit occurs after the first ear surgery has been observed in subjects who underwent bilateral stapedotomies (26). While we were not able to perform statistical testing because of our small sample size, a positive trend was noted with improvement of the ULLs when analyzing first ear and second ear surgeries.…”

Predictors of Listening Capabilities and Patient Satisfaction After Stapes Surgery in Otosclerosis

“…The Belfast rule of thumb is empirically defined, but more commonly used is its graphic derivative (23), the Glasgow Benefit Plot (14,17,19,20,23): normal hearing is a hearing impairment of 30 dB or lesser and symmetrical hearing as interaural difference of 10 dB or lesser. Using this stricter definition of symmetrical hearing in this study would make the small symmetrical hearing group even smaller and further impair statistical comparison among The overall score is the mean score of the 4 listening situations.…”

Evaluating the benefits and outcomes of second ear surgeries in bilateral stapedectomies: a comprehensive analysis

“…The hearing outcome in bilateral otosclerosis has been documented by fewer studies only. 6,7 Database research in the past shows varying results with some studies showing second ear surgery are less successful compared to the first while few other studies have shown satisfactory results in both ears. [16][17][18][19] Our study aimed at providing evidencebased recommendation rather than just an opinion and helps both clinicians and patients getting the valuable based reference data.…”

“…Today with a well experienced hands more than 95% of optimal results can be achieved with a low incidence of complications. [5][6][7] In recent years, there has been an increasing interest in evaluating the benefits and outcomes of second ear surgeries in bilateral stapedectomies. Considering the patient for operating the second ear it is still a dilemma for many surgeons as the risk of immediate or permanent sensorineural hearing loss (SNHL) and vestibular dysfunction exists while exposing for the second time.…”

“…Moreover, some surgeons have reported that they cannot guarantee a similar outcome as that of the first ear. 6,7 It is crucial to monitor and evaluate both auditory and vestibular functions in patients who have undergone second ear surgeries in bilateral stapedectomies. Hence in this study we aim to assess the advantages and results of second ear surgeries in bilateral stapedectomies, in terms of audiological outcomes and functional improvements.…”
