“…19,20 To verify the concept, another 43-year-old male patient with herpes zoster oticus, manifested by eruption, facial paresis, and hearing loss on the right ear, was adopted for comparison. 16 Serological assay confirmed the reactivation of varicella-zoster virus, and MR imaging demonstrated a linear gadolinium-enhanced lesion in the IAC of the right ear ( Figure 3B). Although recovery of facial nerve function was identified, hearing loss on the right ear remained unchanged despite treatment.…”

“…An inner ear test battery including audiometry, cVEMP, oVEMP, and caloric tests, revealed abnormal responses on the lesion ear (Figures 1 and 2), indicating that the respective inner ear end organs, that is, cochlea, saccule, utricle, and semicircular canals were substantially affected. 16 Since vascular insufficiency and autoimmune disease are less relevant in young adults, viral infection may play a dominant role for precipitating SSHL in young adults after dental procedure. Serological assay identified increased varicella-zoster virus IgM antibody titers, further confirmed that SSHL following dental procedure in this young adult is caused by reactivation of the varicellazoster virus.…”

This study investigated the etiology and treatment outcome in sudden sensorineural hearing loss (SSHL) patients following dental procedure. During the past 2 decades, only 6 patients with SSHL following dental procedure were experienced including tooth extraction in 5 and endodontic treatment in 1. Three were males and 3 were females, with ages ranging from 10 to 75 years (median, 47 years). All patients underwent an inner ear test battery. Types of audiogram consisted of total deafness in 3 ears, flat-type loss in 2 ears, and high-tone loss in 1 ear. The pretreatment mean hearing level from 4 frequencies was 76 ± 37 dB for the lesion ears, significantly higher than 23 ± 15 dB for the opposite healthy ears. The treatment outcome is unsatisfactory. Five patients remained hearing unchanged 3 months after treatment. Only 1 (17%) patient had hearing improvement who was proved as having reactivation of the varicella-zoster virus. In conclusion, reactivation of the varicella-zoster virus may be one of the etiologies for SSHL patients following dental procedure. Serological assay coupled with MR imaging may help identify the etiology, determine the medication, and predict the outcome.

“…Vestibular disorders in RHS have been reported more frequently, in 50-80% of cases [13,17]. The different means of investigation (i.e., only caloric tests or a larger number of exams) may justify this wide range.…”

“…The different means of investigation (i.e., only caloric tests or a larger number of exams) may justify this wide range. Huang et al reported that in a sample of 20 subjects, only 40% showed abnormal calorics, while 65% presented pathological cervical vestibular-evoked myogenic potentials (cVEMPs) [17]. Conversely, the authors found that involvement of the eighth nerve was prognostic for poor recovery of facial palsy [18].…”

The varicella-zoster virus (VZV), a member of the Herpesviridae family, causes both the initial varicella infection and subsequent zoster episodes. Disorders of the eighth cranial nerve are common in people with herpes zoster oticus (HZO). We performed a review of the literature on different databases including PubMed and SCOPUS, focusing on cochlear and vestibular symptoms; 38 studies were considered in our review. A high percentage of cases of HZO provokes cochlear and vestibular symptoms, hearing loss and vertigo, whose onset is normally preceded by vesicles on the external ear. It is still under debate if the sites of damage are the inferior/superior vestibular nerves and cochlear nerves or a direct localization of the infection in the inner ear. The involvement of other contiguous cranial nerves has also been reported in a few cases. We report the case of a patient with single-side HZO presenting clinical manifestations of cochleo-vestibular damage without neurological and meningeal signs; after 15 days, the patient developed a new episode of vertigo with clinical findings of acute contralateral vestibular loss. To our knowledge, only three other such cases have been published. An autoimmune etiology may be considered to explain these findings.

“…Therefore, the functional repair of peripheral nerves and pain relief can be effectively promoted. 30 Ultrasound-guided puncture has been proven to be a simple, safe, economic, and less painful microinvasive technique. With ultrasound guidance, doctors can more clearly observe the local structure of the target, the puncture pathway, and the real-time diffusion of local anesthetics, thus greatly improving the success rate of nerve block and reducing complications.…”

Objectives: To compare the clinical outcomes of repetitive paravertebral block (PVB) combining oral medication in the treatment of zoster-related pain (ZP) with different courses.Methods: : Sixty-seven patients with ZP were divided into 3 groups based on their course of herpes zoster Original Article (HZ). Group I: 24 patients with acute herpetic neuralgia (within one month of disease onset); group II: 22 patients with subacute herpetic neuralgia (disease onset from 1 to 3 months); group III: 21 patients with postherpetic neuralgia (more than 3 months since disease onset). All patients received ultrasound-guided repetitive PVB with oral gabapentin and tramadol sustained-release tablets. The VAS and QS scores and the incidences of hematoma, dizziness, nausea, and drowsiness were compared at 1 day, 3 months, and 6 months after treatment.Results: Pain intensity and sleep quality of the 3 groups improved to varying degrees after treatment. The best efficacy was achieved in the acute group, followed by the subacute group, and the poorest efficacy was observed in the chronic group. Conclusion:The efficacy of ultrasound-guided repetitive PVB with oral medication varied with the courses of HZ. The shorter the time since onset, the better the efficacy. This combined treatment showed better efficacy in patients at the acute and subacute stages and significantly improved their pain and sleep quality, while demonstrating limited pain relief in chronic patients.

Test Battery of Cranial Nerves VII and VIII for Assessing Herpes Zoster Oticus

Abstract: Grading of the facial nerve alone fails to predict the outcome of facial paresis in patients with HZO mainly because it overlooks the involvement of CN VIII. Alternatively, a combined test battery of CNs VII and VIII may serve as a strong predictor for facial nerve recovery.
