[Tympanotomy and sealing of the round window membrane in sudden sensorineural hearing loss: a retrospective analysis].
Article in HNO, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe pathogenesis of idiopathic sudden sensorineural hearing loss (ISSHL) still remains unclear. This retrospective study was performed to evaluate the effectiveness of tympanotomy and sealing of the round window membrane after unilateral idiopathic sudden sensorineural hearing loss.
methodsA total of 74 patients with idiopathic sudden sensorineural hearing loss were treated with antiphlogistic-rheologic infusion therapy according to Stennert (steroids and pentoxyphylline). In addition, all patients underwent exploratory tympanotomy and sealing of the round window membrane. Pure tone audiometry was performed pre- and postinterventionally.
resultsThe average hearing loss (four pure tone average) of all patients was 58.9 dB pre-, and 46 dB postinterventionally, which is an average improvement of 12.9 dB. Patients with hearing loss of more than 60% improved significantly compared to patients with hearing loss less than 60% (33.9% vs. +3.3%). Sealing of the round window membrane was found to be more effective when performed within 8 days after ISSHL. A membrane rupture did not lead to better therapy results. No significant correlation was found between therapy outcome and other clinical symptoms.
conclusionSealing of the window membrane shows equal results to conservative methods. If patients with hearing loss of more than 60% have more benefit in tympanotomy with sealing of the window membrane than patients with less hearing loss--as shown as in this study--has to be proved in randomized examinations. Intraoperatively found ruptures of the round window membrane had no significant effect on the therapy outcome.
