    High riding jugular bulb: Is it an etiological factor for benign paroxysmal positional vertigo?
    (2021) Çoban, Kuebra; Kansu, Leyla; Ergun, Tarkan; Aydin, Erdinc
    Introduction: High jugular bulb (HJB) is usually discovered incidentally; however, it may interfere with inner ear structures such as vestibular aqueduct (VA), facial nerve, and the posterior semicircular canal (PSCC). Objective: The aim is to investigate the incidence of HJB in benign paroxysmal positional vertigo patients with PSCC involvement (PSCC-BPPV). Materials and Methods: The study group included 53 consecutive, PSCC-BPPV patients, diagnosed in our clinic. Following the diagnosis, their high resolution computed temporal bone tomography were performed. The control group consisted of 90 patients, who attended to our clinic for various complaints, and to whom high resolution computed tomography of the temporal bone was conducted. Results: The incidence of HJB in the study group was 41.5% (n = 22). The incidence of ipsilateral HJB in this group was 28.3% (n = 15). The incidence of HJB in the control group was 11.1% (n = 10) (P < 0.001). The closest distance between HJB and PSCC canal in the control and study groups was 1.61 +/- 0.74 mm and 1.17 +/- 0.37 mm, respectively (P = 0.098). Conclusion: The HJB is significantly more frequent in PSCC-BPPV patients. Furthermore, the rate of incidence of HJB in the ipsilateral ears of these patients is significantly higher. Venous hypertension or the turbulence may cause strong pulsations, which influence the detachment of the otoconia into the PSCC.

    Upright positioning-related reverse nystagmus in posterior canal benign paroxysmal positional vertigo and its effect on prognosis
    (2020) Jafarov, Sabuhi; Hizal, Evren; Bahcecitapar, Melike; Ozluoglu, Levent N.; 0000-0002-2150-0237; 0000-0002-9699-6783; 0000-0002-7302-4199; 32597824; AAI-8020-2021; A-5853-2018; AAI-8044-2021
    BACKGROUND: Positional nystagmus elicited by the Dix-Hallpike maneuver often reverses its direction as the patient is re-seated from the provoking head hanging position. The incidence of reverse nystagmus and its association with prognosis in posterior canal benign paroxysmal positional vertigo (pcBPPV) is not clear. OBJECTIVE: To determine the incidence of upright positioning-related reverse nystagmus and its association with the success of canalith repositioning (Epley) maneuver (CRM) treatment in pcBPPV. METHODS: The records of patients that had been tested with video-nystagmography in a tertiary care center, between October 2016 and March 2019, were reviewed. Data were obtained from detailed analysis of video recordings of 321 patients with typical pcBPPV. RESULTS: Reverse nystagmus was determined in 85% of the patients with pcBPPV. The number of CRMs required for treatment was lower in patients with reverse nystagmus (1.32 +/- 0.68) compared to patients without reverse nystagmus (1.81 +/- 0.98) (p < 0.001). There was not a statistically significant relationship between reverse nystagmus and recurrence (p = 0.623). CONCLUSIONS: The absence of reverse nystagmus on upright positioning during the Dix-Hallpike test predicts poor success for the CRM, as repetitive repositioning maneuvers might be required to achieve successful treatment in pcBPPV.

    Benign Paroxysmal Positional Vertigo After Nonotologic Surgery: Case Series
    (2015) Kansu, Leyla; Aydin, Erdinc; Gulsahi, Kamran; 25838683
    Benign paroxysmal positional vertigo is one of the most common types of vertigo caused by peripheral vestibular dysfunction. Although head trauma, migraine, longterm bed rest, Menie're disease, viral labyrinthitis, and upper respiratory tract infections are believed to be predisposing factors, most cases of benign paroxysmal positional vertigo are idiopathic. Ear surgery is another cause, but after nonotologic surgery, attacks of benign paroxysmal positional vertigo are rare. We describe three cases of benign paroxysmal positional vertigo attacks after non-otologic surgery (one patient after a nasal septoplasty and two patients after dental endodontic treatment) and discuss the pathophysiological mechanismof benign paroxysmal positional vertigo seen after non-otologic surgery, its diagnosis and treatment

    Benign Paroxysmal Positional Vertigo in Pregnancy
    (2017) Coban, Kubra; Yiğit, Nilufer; Aydin, Erdinc; 29392061
    Benign paroxysmal positional vertigo (BPPV) is a clinical entity characterized by acute, brief paroxysmal attacks of rotational vertigo induced by head position changes. It is the most common peripheral vestibular pathology and is seen more frequently in women. However, to our knowledge, there is very limited data on the association between BPPV and pregnancy in both English and Turkish literature. We present four pregnant women diagnosed with BPPV for the first time during gestation and revise the etiological factors of BPPV and the role of pregnancy-related changes in BPPV.
