“…This has practical implications for both the patient and the surgeon. 7 Noise exposure results in dysfunction of the outer hair cells, which may produce a temporary hearing loss on surgery applied or other ears. 8 Tympanoplasty can also cause a SNHL by a mechanism of acoustic trauma.…”

Objective: In otology, a wide variety of devices are used that have significant noise output, both operated ear and the patient. We aimed to determine hearing damages due to drill-generated acoustic trauma in ear surgery. We want to find how degree drill-generated acoustic trauma is responsible from sensorineural hearing loss in ear surgery. Materials and methods:We designed a retrospective study about 100 patients who underwent radical or modiphied radical mastoidectomy and tympanoplasty. The audiometric testing was done both pre and postoperatively to detect any significant hearing loss in the immediate postoperative period. The data were analyzed using the Wilcoxon sign and Mann-Whitney U tests. This study proposes that hearing loss is caused by drill noise conducted to the operated ear by vibrations of temporal bone.Results: A sensorineural hearing loss soon after mastoid surgery is seen due to the noise generated by the drill. Mean pure-tone thresholds obtained was significantly more in mastoidectomy applied patients when compared to tympanoplasty . Mean bone conduction (BC) hearing levels impaired 6,6 dB in 1 kHz ,5.5 dB in 0.5 kHz , 5 dB in 4.kHz and 3.1 dB in 2 kHz in mastoidectomy groups but improved 5.5 dB in 0.5 kHz, 2.2 dB in 1 kHz , 2.7 dB in 2 kHz in tympanoplasty groups. Statistically significant differences were observed at the 0.5-1 and 4 kHz frequencies pre and postoperative in the hearing thresholds of BC changing in mastoidectomy group, however, the averages of ranks of all pre and postoperative measurement of hearing levels show differences between mastoidectomy and tympanoplasty groups was significant in statistically at independent groups (p < 0.05). Conclusion:We conclude that drill-generated noise during mastoid surgery has been incriminated as a cause of sensorineural hearing loss. Drilling during mastoid surgery may result in temporary or permanent noise-induced hearing loss. Possible noise disturbance to the inner ear can only be avoided by minimizing the duration of harmful noise exposure and carefull using burr to near the cochlear structures.

“…The expected hearing loss may be missed if pure tone audiometry is utilized [3,4] . Although Da Cruz et al [5] reported drill-induced contralateral temporary hearing loss by changes in amplitudes of distortion product OAEs (DPOAEs), longitudinal recovery of this temporary hearing loss has not been studied before.…”

Mastoid drilling can cause transient hearing loss in the contralateral normal hearing ear. A study was designed to evaluate hearing in the contralateral normal ear before and after the mastoid surgery in a longitudinal manner and find out the duration of this temporary hearing loss. Twenty-two patients requiring mastoid surgery in their diseased ears, having contralateral normal ear were included. Pure tone audiometry and otoacoustic emissions (OAEs) were utilized for baseline evaluation. OAEs were repeated during the immediate postoperative period and daily up to the 6th postoperative day. The amplitudes of the OAEs of contralateral normal ears were found affected immediately after surgery and progressive improvement was detected with full recovery at 72–96 h. None of the patients had permanent deterioration in OAE amplitudes. The burs used during mastoid surgery can cause temporary hearing threshold changes in the contralateral ears. This adverse effect recovers spontaneously within 72–96 h postoperatively.

“…Urquhart et al (12) reported in their study that they did not find early hearing loss associated with vibration after drilling, but they stated that long-term effects of drilling were unknown. In this study conducted in 1992, standard audiometric analysis was performed to test hearing.…”

Objective: We aimed to evaluate the vibration effect of drilling on facial nerve motor functions during mastoidectomy and to investigate the impact of this round of interest with its duration of use.Methods: Twenty-three patients with a diagnosis of chronic otitis media were enrolled. Using electroneurography, all patients were determined to have pre-and postoperative bilateral facial nerve. The duration of drill during the operation was calculated, and the possible damage over the nerve and its association with the duration of drilling were investigated. Results:The study included 23 patients, with 10 (43.5%) male and 13 (56.5%) female patients, There was no statistically significant deteriorating effect on facial nerve motor functions (p>0.05). Conclusion:It is currently considered that facial nerves might be damaged only by direct contact during mastoidectomy. However, the nerves could be damaged by the vibration and temperature effects of the drill. Therefore, unnecessary drilling in the mastoid cavity should be avoided, and blunt-ended drills should be used.
