Comparison of the effects of the temperature of intratympanic dexamethasone injections on vertigo

Post-stapedotomy dizziness after applying topical steroid on footplate: A randomized controlled trial

Background

Otosclerosis is characterized by abnormal bone growth in the otie capsule. Nowadays, stapedotomy is commonly used for otosclerosis treatment. Currently, postoperative dizziness has been associated with stapedotomy. In 1981, intratympanic dexamethasone was utilized to manage inner ear disorders like tinnitus and acute sensorineural hearing loss. However, there is much uncertainty regarding the effect and safety of topical steroid therapy in the middle ear during stapedotomy. In the present study, we assessed the effect of topical steroid therapy during stapedotomy on postoperative dizziness.

Methods

Otosclerosis patients eligible for stapedotomy were randomly divided into two groups based on dexamethasone administration or placebo. Audiometric and tympanometry results were observed and recorded for the involved frequencies. The Dizziness Handicap Inventory was used to quantify patient perceptions of dizziness and balance issues. Audiometry and dizziness assessments were repeated at discharge and 4 months after the operation.

Results

The study comprised 72 otosclerosis patients undergoing stapedotomy. At discharge, the intervention group showed a significant reduction in the incidence of dizziness compared to the placebo group. However, in the 4-month follow-up after the operation, both groups experienced a decrease in dizziness incidence, with no significant difference between them. There was also no significant difference in audiometric levels between the two groups. Interestingly, the intervention group had a significantly lower need for systemic anti-dizziness drugs after surgery compared to the control group.

Conclusion

Topical dexamethasone during stapedotomy effectively minimizes dizziness at discharge and reduces the need for postoperative anti-dizziness medication.

[Tolerance and acceptance of intratympanic injections]

Hintergrund

Die intratympanale Gabe von Steroiden ist Bestandteil der Therapie von akuten Hörverlusten. Bislang existieren nur wenig Daten zur Akzeptanz und Toleranz aus Sicht der Patient*innen.

Material und Methoden

Zu den gesundheitlichen Voraussetzungen und den Umstäden ihrer intratympanalen Therapie wurden 84 Patient*innen befragt.

Ergebnisse

Es stellten sich 38 Frauen und 46 Männer im Alter von durchschnittlich 57,2 Jahren meist auf Empfehlung ihres HNO-Arztes zur Zweitlinientherapie vor und empfanden die Injektionen zu 3,6 % als schmerzhaft, 22,6 % unangenehm, 67,9 % erträglich und zu 41,7 % als schmerzfrei (Mehrfachnennungen möglich). Eine Weiterempfehlung gaben 77,4 %, eine fehlende Empfehlung resultierte aus mangelnder Wirkung und unangenehmer Empfindung.

Schlussfolgerung

Der weit überwiegende Anteil der Behandelten beurteilt die intratympanale Therapie als erträglich und gibt eine Weiterempfehlung. Die enge Patientenführung ist ein entscheidender Therapiebaustein.

Effect of video-assisted information prior to intratympanic steroid injection on patient anxiety

OBJECTIVE

Patients may be afraid when they receive knowledge that medications are injected into the middle ear through the tympanic membrane using a fine needle during intratympanic treatment. The aim of this study was to evaluate the effect of video-assisted information prior to intratympanic steroid injection on patient anxiety.

STUDY DESIGN

Prospective, Non-randomized, controlled trial.

SETTING

Tertiary academic medical center.

METHODS

A total of 85 patients who had an indication for intratympanic treatment due to idiopathic sudden sensorineural hearing loss and tinnitus were included in this prospective study. 40 cases received video-assisted information before intratympanic steroid injection in the study group, while 45 cases were verbally informed face-to-face in the control group. Then, patient anxiety was measured using the Visual Analog Scale (VAS) and Spielberger State-Trait Anxiety Inventory (STAI).

RESULTS

The mean VAS score was 3.58 ± 3.37 (mean rank = 42.09) in the study group and 3.87 ± 3.56 (mean rank = 43.81) in the control group. The mean STAI-S score was 37.03 ± 10.637 in the study group and 39.11 ± 11.783 in the control group. The mean STAI-T score was 40.18 ± 9.151 in the study group and 38.73 ± 11.438 in the control group. It was found that there were no statistically significant differences in the mean VAS, STAI-S and STAI-T scores between the two groups (p > 0.05).

CONCLUSION

We revealed that video-assisted information prior to intratympanic steroid injection had no superiority in reducing anxiety over face-to-face verbal information.
