1 · What the graph read from it

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.

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.

Abstract

purposeWe aimed to evaluate the speech intelligibility benefit in noise provided by stapedotomy in the treatment of unilateral otosclerosis.

methodsWe enrolled adults suffering from unilateral conductive hearing loss and followed them up until 9 months after surgery. The patients underwent a free field speech hearing evaluation using the French Matrix test before and after stapedotomy. Speech material was sent to the front of the patients (S0) and noise was presented either at the front (N0), or at the operated ear (N-90) or at the non-operated ear (N + 90). The speech intelligibility benefit in noise was assessed by comparing Squelch effect (SE), Head shadow effect (HS) and Binaural redundancy (BR) before and after surgery. SE was measured as the difference in speech reception thresholds (SRT) between S0N + 90 situations before and after surgery, HS as the difference in SRT between S0N + 90 and S0N-90 situations, and BR as the difference in SRT between S0N0 situations before and after surgery. In addition, two quality of life's questionnaires were completed by patients to evaluate their discomfort.

resultsAmong 25 patients, 19 were followed up during 9 months, 4 were excluded and 2 were lost for the following-up. Stapedotomy provided a restoration of SE of 3.7 dB SNR (p < 0.001) and a BR gain of 1.8 dB SNR (p < 0.001). HS did not show any statistical variation after surgery (p = 0.077). Finally, the questionnaires showed a residual hearing discomfort.

conclusionStapedotomy provided a binaural benefit with the restoration of the SE and BR but which remained lower than in the normal-hearing population.
