Vibration Effect of Drill on Facial Nerve Motor Functions During Mastoidectomy

Objective & Hypothesis: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.

📊

Key Findings & Data: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 & Impact:Therefore, unnecessary drilling in the mastoid cavity should be avoided, and blunt-ended drills should be used.

Abstract

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.

Özet

Amaç: Mastoidektomi sırasında turun oluşturduğu vibrasyonun, fasial sinirin motor fonksiyonları üzerine bir etkisinin olup olmadığı; varsa bu etkilenmenin tur kullanma süresi ile ilgilisinin araştırılması amaçlandı.Yöntemler: Kronik Otitis Media (KOM) tanısı ile mastoidektomi uygulanan 23 hastaya, preoperatif ve postoperatif olarak bilateral fasiyal sinir elektronörografisi yapıldı. Operasyon sırasında turlama süresi hesaplanarak fasiyal sinir üzerindeki muhtemel hasar ve bu hasarın turlama süresi ile olan ilişkisi araştırıldı.Bulgular: Çalışma 23 hasta üzerinde gerçekleştirildi. Hastaların 10 (%43,5)'u erkek, 13 (%56,5)'ü kadındı. Yapılan istatistiksel analizde fasiyal sinir motor fonksyonlarında anlamlı bir bozulma saptanmadı (p>0,05). Sonuç: Günümüzde fasiyal sinirin mastoidektomi sırasında sadece direk temas ile hasarlanabileceği düşünülmektedir. Ancak turun yarattığı vibrasyon ve ısı sonucu fasiyal sinir zedelenebilir. Bu nedenle mastoid kavitede gereksiz ve kör uçlar kullanılarak yapılan turlamadan kaçınılmalıdır.
