Benign paroxysmal positional vertigo and post-treatment quality of life

Benign paroxysmal positional vertigo is probably the most common cause of vertigo. It is characterized by acute short-lived episodes of severe vertigo in association with change in the position of the head. This condition is benign, and after the repositioning procedure, the cure rate is between 70 to 80%. Numerous studies describe the association between vertigo and social handicap and emotional disturbance. In our study, we report for the first time the level of anxiety and social consequences, tested with the Hamilton anxiety scale and vertigo handicap questionnaire, in a group of patients who had suffered only from positional vertigo and were clinically cured when the questionnaires and test were administered. The important role played by psychological factors in maintaining or increasing the social consequences and perception of vertigo is revealed in this study.     

Benign paroxysmal positional vertigo after dental surgery

We investigated the relationship between dental and maxillofacial surgery and benign paroxysmal positional vertigo (BPPV). BPPV represents the most frequent cause of vertigo of labyrinthine origin. BPPV has been reported following surgical trauma from various surgical interventions, regarding anatomical site and technical execution. A surgical origin is, in many cases, supported by the temporal relation to the surgical intervention as well as by the clinical picture. We considered eight BPPV cases of suspected iatrogenic origin focusing our attention on dental surgery with particular reference to surgical extraction of included teeth through rotating tools. The cases taken into account had no other inner ear disease and BPPV risk indicator. We conclude that dental surgery is a risk factor for BPPV.     

Epley's canalith-repositioning manoeuvre for benign paroxysmal positional vertigo

The efficacy of the Epley's canalith-repositioning manoeuvre in the treatment of BPPV was assessed in this prospective study of 62 patients. Patients were selected based on symptoms of positional vertigo and positive Dix-Hallpike's positional test. Patients were divided into two groups; first group comprising 34 patients underwent Epley's manoeuvre alone where as the other group comprising 28 patients underwent Epley's manoeuvre along with mastoid oscillator. At the end of 1 month patients were assessed subjectively by visual analogue scale (VAS) and objectively by Dix-Hallpike's positional test. On VAS, 85.7% patients had complete resolution of symptoms of BPPV in both the groups. Objectively 88.2% did not have positional nysfagmus after 1 month in first group whereas in the second group 86% had complete response at the end of 1 month of therapy. Follow up of 6 months could be done in 38 patients, out of which 7 (18.4%) had recurrence of their symptom of vertigo and positive Dix-Hallpike's positional test, whereas one patient continued to have no relief by Epley's manoeuvre. There was no difference in subjective and objective parameters even when CRP was performed using mastoid vibrator.     

Differentiation of migrainous positional vertigo (MPV) from horizontal canal benign paroxysmal positional vertigo (HC-BPPV)

This article presents an approach to differentiation of migrainous positional vertigo (MPV) from horizontal canal benign paroxysmal positional vertigo (HC-BPPV). Such an approach is essential because of the difference in intervention between the two disorders in question. Results from evaluation of the case study presented here revealed a persistent ageotropic positional nystagmus consistent with MPV or a cupulolithiasis variant of HC-BPPV. The patient was treated with liberatory maneuvers to remove possible otoconial debris from the horizontal canal in an attempt, in turn, to provide further diagnostic information. There was no change in symptoms following treatment for HC-BPPV. This case was diagnosed subsequently as MPV, and the patient was referred for medical intervention. Treatment has been successful for 22 months. Incorporation of HC-BPPV treatment, therefore, may provide useful information in the differential diagnosis of MPV and the cupulolithiasis variant of HC-BPPV.

Benign paroxysmal positional vertigo after stapedectomy

OBJECTIVE: To determine the incidence of benign paroxysmal positional vertigo (BPPV) following stapedectomy in a patient group and the efficacy of the Epley maneuver in this group. STUDY DESIGN: Prospective study in a university-based tertiary referral system. METHODS: The patient group comprised 63 patients who had undergone stapedectomy; a control group consisted of normal healthy individuals with no otolaryngological complaints. All individuals underwent the Dix-Hallpike maneuver for the diagnosis of BPPV. Patients who exhibited vertigo, torsional nystagmus (which reverses its direction on return to sitting position) preceded by a latent period, and the fatigability of these findings were considered to have BPPV. If the test result was positive, they underwent the Epley therapeutic maneuver. RESULTS: Four of the patients who had undergone a stapedectomy showed characteristic findings of BPPV. No individual in the control group had BPPV. All patients responded well to the Epley maneuver. CONCLUSIONS: Stapedectomy may be regarded as an etiological factor in BPPV. Because the fenestra is located in the posterior part of the stapes footplate, the pathophysiology appears to be related to utricular rather than saccular trauma. Correct measurement of the distance between the incus and stapes footplate is essential in stapedectomy. An Internet survey of the relevant literature in English shows a scarcity of publications on the incidence of BPPV following stapedectomy. In the present study, 63 patients who had undergone a stapedectomy were investigated for the presence of BPPV; all had Dix-Hallpike maneuvers performed for the diagnosis. Sixty-three individuals with no otolaryngological complaints made up the control group. Four of the patients who had undergone stapedectomy showed characteristic findings of BPPV, and no individual in the control group had BPPV; the difference between the two groups was statistically significant. All four of the patients diagnosed with BPPV responded well to the Epley maneuver. The pathophysiology appears to be related to utricular trauma. Correct measurement of the distance between the incus and stapes footplate is essential in stapedectomy.

Canal switch after canalith repositioning procedure for benign paroxysmal positional vertigo

Canal switch is a complication following canalith repositioning procedure (CRP) for posterior canal benign paroxysmal positional vertigo (BPPV). Instead of being returned to the utricle, the loose otoconia migrate into the superior or horizontal semicircular canal. Patients remain symptomatic, and treatment can be ineffective unless the switch is recognized and additional repositioning maneuvers directed toward the appropriate semicircular canal are performed. This report provides the first videographic documentation of canal switch involving conversion of unilateral posterior semicircular canal BPPV to geotropic horizontal canalithiasis.
