Abstract
Background: Rhinoplasty is a common surgical procedure that is requested and accepted by patients for cosmetic and functional reasons. Osteotomies are performed on nasal bone, maxillary crest, or vomer to fix the deviations of the nasal dorsum or septum. During the percussion of the osteotomes with the surgical mallet, the vibration energy diffuses to the cranium. Auditory and vestibular systems may be affected by these vibrations.
Objectives: To assess the effects of rhinoplasty, in which osteotomies were performed using a hammer, on the audiovestibular system.
Methods: Thirty adults who underwent rhinoplasty were included in the study group. Ten age and gender matched adults who had nasal surgery without surgical mallet or osteotome served as the control group. The patients in both groups were assessed using pure tone audiometry, tympanometry, distortion product otoacoustic emission testing, and vestibular evoked myogenic potential, as well as video head impulse tests (vHIT) before the operation and one week after the operation.
Results: On auditory assessment, there was no significant difference between the study and control groups regarding pure tone thresholds at frequencies of 250 Hz to 8 kHz (p>0.05) as well as otoacoustic emissions. The vestibular assessment performed by using vestibular evoked myogenic potential and vHIT did not reveal a statistically significant difference between the groups, before surgery, and after surgery (p>0.05).
Conclusions: Rhinoplasty appears to be a safe operation in terms of audiovestibular functions, and osteotomy, in which a hammer is usually used, does not have an impact on hearing and balance functions of the ear.
