“…The present results emphasize the importance of a systematic follow-up to assess the impact of plugging of a semicircular canal on inner ear function. Systematic objective vestibular results are lacking and reported outcomes vary between studies [11,15,16,[18][19][20][26][27][28]. Mantokoudis et al evaluated three patients up to 1-4 months after plugging of the superior semicircular canal through a middle cranial fossa approach and showed recovery of lateral semicircular canal gain in 3/3 patients, while 1/3 showed recovery of posterior semicircular canal gain [15].…”

“…Previous studies have reported cases of transient hearing loss [12], persistent (high-frequency) sensorineural hearing loss [12][13][14], a decrease in vestibulo-ocular reflex (VOR) gain of all ipsilateral semicircular canals [15,16], or an increase in semicircular canal paresis, up to caloric areflexia [17][18][19]. Unfortunately, structured data on the occurrence of these side effects is lacking, especially regarding objective vestibular function [11,20]. Furthermore, since many studies use a single moment of postoperative evaluation and the follow-up interval differs between studies, assessment of the evolution of inner ear function over time is impeded [11,20].…”

Background Certain cases of superior semicircular canal dehiscence or benign paroxysmal positional vertigo can be treated by plugging of the affected semicircular canal. However, the extent of the impact on vestibular function and hearing during postoperative follow-up is not known. Objective To evaluate the evolution of vestibular function and hearing after plugging of a semicircular canal. Methods Six patients underwent testing before and 1 week, 2 months, and 6 months after plugging of the superior or posterior semicircular canal. Testing included caloric irrigation test, video Head Impulse Test (vHIT), cervical and ocular Vestibular Evoked Myogenic Potentials (VEMPs) and audiometry. Results Initially, ipsilateral caloric response decreased in all patients and vHIT vestibulo-ocular reflex (VOR) gain of each ipsilateral semicircular canal decreased in 4/6 patients. In 4/6 patients, postoperative caloric response recovered to > 60% of the preoperative value. In 5/6 patients, vHIT VOR gain was restored to > 85% of the preoperative value for both ipsilateral non-plugged semicircular canals. In the plugged semicircular canal, this gain decreased in 4/5 patients and recovered to > 50% of the preoperative value. Four patients preserved cervical and ocular VEMP responses. Bone conduction hearing deteriorated in 3/6 patients, but recovered within 6 months postoperatively, although one patient had a persistent loss of 15 dB at 8 kHz. Conclusion Plugging of a semicircular canal can affect both vestibular function and hearing. After initial deterioration, most patients show recovery during follow-up. However, a vestibular function loss or high-frequency hearing loss can persist. This stresses the importance of adequate counseling of patients considering plugging of a semicircular canal.

“…Some surgeries have been performed in cases of intractable BPPV. In particular, canal plugging of the posterior canal has been reported [16,17]. This surgical effect depends on stopping ampullopetal and ampullofugal endolymph flow and its effect on the ampulla.…”

Background: There have been no useful imaging methods to diagnose benign paroxysmal positional vertigo (BPPV), a common cause of vertigo, depending on the characteristic symptom. Objective: To visualize horizontal canal (HC) BPPV using 3DCT and assess its clinical usefulness. Subjects and methods: Ten BPPV patients were diagnosed with distinct BPPV, canalolithiasis, and cupulolithiasis of the HC (hc-BPPV, hc-BPPV-cu), which were definitely diagnosed on the basis of criteria of BPPV by the Barany Society and 10 healthy subjects without a history of dizziness were investigated using 3DCT with several different CT window values (CTWVs). Results: The HCs of BPPV patients were clearly visualized and the luminal aspects showed differences among ears with cupulolithiasis, canalolithiasis and no symptoms healthy subjects. Conclusions and significance: 3DCT images visualized the characteristic changes of the HC of patients with BPPV compared to healthy subjects. The HC images were coincident with the clinical condition of cupulolithiasis and canalolithiasis. This imaging technique is clinically useful for diagnosing, treating and assessing the prognosis of HC BPPV ARTICLE HISTORY

“…Posterior canal plugging poses a substantial risk to hearing (3-20%), but success rate is about 85 to 90%. 12 Gacek proposed transaction of the posterior ampullary nerve for relief of BPPV. Most of the studies done earlier have compared the effectiveness of maneuvers but in this study, we compared the effectiveness of Cawthorne Cooksey exercise with Brandt Daroff exercise in patients with residual symptoms after successful Epley's maneuver.…”

Background: Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vertigo. Vertigo and balance disorders are among the most common symptoms experienced in patients who visit ENT outpatient department. BPPV is a common vestibular disorder leading to significant morbidity and psychosocial impact. Residual dizziness is a common condition that manifests as persistent disabling imbalance after successful repositioning maneuvers for BPPV.Methods: In this study we analysed and compared the effectiveness of Cawthorne Cooksey Exercise with Brandt Daroff Exercise to treat residual dizziness after successful Epley’s maneuver for posterior canal benign paroxysmal positional vertigo. A total of 30 subjects with residual dizziness after successful Epley’s maneuver for posterior canal BPPV were included in our study, 10 were male and 20 were female. The Group A received the Cawthorne Cooksey exercise post Epley’s maneuver and Group B received the Brandt Daroff exercise post Epley’s maneuver. Results: We conclude that both the groups have significant improvement in their symptoms and balance. This was indicated by the results. Despite the significant results within the groups, there was no significant difference between the groups, means both exercises showed almost equal improvement in their respective group.Conclusions: This study concludes that both Cawthorne Cooksey exercise and Brandt Daroff exercise are helpful in treating residual dizziness after successful Epley’s maneuver in posterior canal BPPV patients. These exercises are safe and able to reduce subjective symptoms and imbalance hence, any of these can be recommended for treating post Epley’s residual dizziness in patients with posterior canal BPPV.
