Summary

SUMMARY Intratympanic injections commonly cause pain in the patients. Intratympanic steroid injection (ITS) application can be performed by direct injection without anesthesia or with local anesthesia induced by lidocaine spray, lidocaine injection, topical phenol, pantocaine, EMLA cream (lidocaine+prilocaine) or vibration anesthesia device (VAD). The advantage of VAD application over other anesthetic agents was that it eliminated the need to use local anesthetics that may disrupt wound healing. In addition, inducing anesthesia with VAD can be considered as an alternative method in patients allergic to drugs.

Detailed description

ABSTRACT In this study, we aimed to compare the efficacy of four methods including topical lidocaine spray, local anesthetic cream, vibration anesthesia device (VAD), and saline drops (control group) in the reduction of pain after intratympanic steroid injections (ITS's) and to demonstrate the effectiveness of VAD use. The prospective study included 40 patients aged 18-70 years with idiopathic sudden sensorineural hearing loss. Prior to each ITS, all the four methods including local anesthetic cream (EMLA® cream, AstraZeneca PLC), lidocaine spray (Vemcain® Spray), VAD (Blaine®, Blaine Labs, Santa Fe, USA), and saline drops (control) were administered in each patient. After each ITS, pain assessment was performed using Visual Analogue Scale (VAS), Numerical Rating Scales (NRS), and Verbal Rating Scales (VRS).

Type	Name	Description
DEVICE	Vibration Anesthesia Device (VAD)	In conclusion, induction of anesthesia with VAD in patients treated with ITS provided pain palliation in a similar way to other local anesthetic techniques. Moreover, the advantage of VAD application over other anesthetic agents was that it eliminated the need to use local anesthetics that may disrupt wound healing. In addition, inducing anesthesia with VAD can be considered as an alternative method in patients allergic to drugs. Our study will shed light on different techniques such as the application of ventilation tube in anesthesia with VAD.
DRUG	local anesthetic cream	Prior to each ITS, all the four methods including local anesthetic cream (EMLA® cream, AstraZeneca PLC), lidocaine spray (Vemcain® Spray), VAD (Blaine®, Blaine Labs, Santa Fe, USA), and saline drops (control) were administered in each patient. The order of administration was determined for each patient using the randomization software (random.org/lists/). For the fifth ITS, however, the method of administration was selected by the patient.
DRUG	lidocaine spray	Prior to each ITS, all the four methods including local anesthetic cream (EMLA® cream, AstraZeneca PLC), lidocaine spray (Vemcain® Spray), VAD (Blaine®, Blaine Labs, Santa Fe, USA), and saline drops (control) were administered in each patient. The order of administration was determined for each patient using the randomization software (random.org/lists/). For the fifth ITS, however, the method of administration was selected by the patient.
OTHER	saline drops	Prior to each ITS, all the four methods including local anesthetic cream (EMLA® cream, AstraZeneca PLC), lidocaine spray (Vemcain® Spray), VAD (Blaine®, Blaine Labs, Santa Fe, USA), and saline drops (control) were administered in each patient. The order of administration was determined for each patient using the randomization software (random.org/lists/). For the fifth ITS, however, the method of administration was selected by the patient.
