“…Dead ear was rarely reported, usually with figures under 1% [Smyth, 1977;Tos et al, 1984;Vartiainen and Seppä, 1997], although one paper reported 13% dead ears, which was attributed to the use of chlorhexidine in the preoperative sterilization [Bicknell, 1971]. Bone threshold conduction impairment after myringoplasty has been attributed to manipulation of the intact ossicular chain, use of the drill, and suction irrigation during surgery [Parkin et al, 1980;Katzke and Sesterhenn, 1982;Basset et al, 1985;Bellucci, 1985;Black and Wormald, 1995], but the contribution of these procedures to postoperative sensorineural hearing impairment is controversial. Ossicular manipulation, even when studied by electrocochleography [Kylén et al, 1980], has not been associated with significant bone threshold conduction impairment [Völter et al, 2000].…”

Introduction: Inner ear function can be modified by middle ear surgery. Objectives: This study aimed to describe bone threshold conduction changes after myringoplasty. Design: Prospective study. Materials and Methods: Determination of preoperative and 6- to 12-month postoperative bone conduction thresholds for patients consecutively treated by primary underlay myringoplasty. Results: The mean bone conduction threshold improvement was 1 ± 6 dB (p = 0.006). There were significant differences in bone conduction threshold changes by surgical approach and for patients with tympanosclerosis. There were no ‘dead ears’ following intervention, and only a 1% risk of impairment. Conclusions: Anatomically successful myringoplasty can partially improve bone conduction with minimal risk of impairment.

“…Sensori neural hearing loss has been observed after middle-ear surgeries such as type I tympanoplasty (with or without mastoidectomy) and stapedectomy [2][3][4][5][7][8][9], After type I tympanoplasty, sensorineural hearing loss has been reported to range from 0.12 to 18.5% [5,6], Frequencies between 2 and 8 kHz appear to be most commonly affected, and hearing loss has also been reported to range from 3 to 17 dB [1,3,4,6,10].…”

“…Manipulation of the eardrum can produce pressure changes at the stapes footplate corresponding to 140 dB SPL [11], Drilling with an intact ossicular chain in temporal preparations has been noted to produce stapes footplate movements corre sponding to 130-150 dB SPL [12]. Depending on the size of the tip utilized, suctioning has been found to produce noise levels as severe as 150 dB SPL [ 10,13].…”

100 patients were tested in a prospective, randomized, double-blinded study to assess the perioperative efficacy of a calcium channel blocker (diltiazem) in preventing acoustical trauma during otologic surgery. The patients were randomly divided into a therapy group (diltiazem) and a control group (placebo). Bone conduction hearing thresholds were examined preoperatively and again 1 day and 3 months postoperatively. Frequency-dependent changes in postoperative bone conduction and the number of patients with various degrees of postoperative hearing loss in both groups were statistically analyzed. The results indicated only a small postoperative hearing loss after ear surgery in both groups. There was a tendency for better results in the therapy group, but this was not statistically significant. Despite favorable results in animal trials utilizing different types of noise and the prophylactic application of diltiazem, further studies in humans are needed to determine the role of calcium antagonist drugs in the prophylaxis or treatment of acoustical trauma.

Objective To determine sound levels resulting from aural suctioning of the external auditory canal. Methods Unweighted decibels (dB) and A‐weighted decibels (dBA) sound pressure level measurements were recorded using a retrotympanic microphone in cadaveric human temporal bones. Sound measurements were made with common otologic suctions, size 3, 5, and 7 French, within the external ear canal at the tympanic membrane, 5, and 10 mm from the tympanic membrane in the dry condition. In the wet condition, the ear canal was filled with fluid and completely suctioned clear to determine sound effects of suctioning liquid from the ear canal. Results Sound levels generated from ear canal suctioning ranged from 68.3 to 97 dB and 62.6 to 95.1 dBA. Otologic suctions positioned closer to the tympanic membrane resulted in louder sound levels, but was not statistically significant (P > .05). Using larger diameter suctions generated louder dB and dBA sound levels (P < .001) and the addition of liquid in the ear canal during the suction process generated louder dB and dBA sound levels (P < .001). Conclusions Smaller caliber suction sizes and nonsuctioning techniques should be utilized for in‐office aural toilet to reduce noise trauma and patient discomfort. Level of evidence 5
