Benign paroxysmal positional vertigo diagnosis and treatment

An October 2022 paper (1) from the Department of Otorhinolaryngology-Head and Neck Surgery, Osaka University Graduate School of Medicine, Osaka, Japan gives us the latest insights into the problem of Benign paroxysmal positional vertigo. A summary and brief explanatory notes of this paper are below.

“Benign paroxysmal positional vertigo (BPPV) is characterized by positional vertigo (brief attacks of rotatory vertigo triggered by head position changes in the direction of gravity) and is the most common peripheral cause of vertigo. There are two types of BPPV pathophysiology: canalolithiasis and cupulolithiasis. In canalolithiasis, otoconial debris is detached from the otolithic membrane and floats freely within the endolymph of the canal.”

Canalolithiasis

Explanatory Note: This debris inside your ear are tiny crystals of calcium carbonate (the stuff that antacids are made of). They are sometimes referred to as “ear rocks” as a more descriptive and understandable term than the more medical “otoconial.” The problem is caused by these rocks floating into the ear canals. More precisely these ear rocks detached from the otolithic membrane (the tissue in the vestibular system of the inner ear that helps the brain understand equilibrium) and floats freely within the endolymph (the fluid of the inner ear). Further broken down into posterior-canal-type BPPV and lateral-canal-type BPPV.

Posterior canal type BPPV

Lateral-canal-type BPPV

Cupulolithiasis

In cupulolithiasis, the otoconial debris released from the otolithic membrane settles on the cupula of the semicircular canal and the specific gravity of the cupula is increased.

Explanatory note: The cupula is the membrane covering the crista ampullaris of the semicircular canal The crista ampullaris senses the rotation of the head and helps convey messages to the brain to maintain balance.

The researchers of this study point out that during the medical examination of a patient with suspected BPPV, questions regarding the characteristics of vertigo, triggered movement of vertigo, duration of vertigo and cochlear symptoms during vertigo attacks are important for the diagnosis of BPPV.

The canalith repositioning procedure

The canalith repositioning procedure can move the ear rocks or debris to other parts of the ear where they cause no symptoms. The procedure involves several simple head movements. The canalith repositioning procedure for posterior canal type BPPV is called the Epley maneuver, and the CRP for lateral canal type BPPV is called the Gufoni maneuver.

When Benign paroxysmal positional vertigo treatment procedures do not work

We are going to go now to a July 2022 study in the journal European archives of oto-rhino-laryngology (2) that investigated the risk factors for residual dizziness (RD) in patients with benign paroxysmal positional vertigo (BPPV) after successful repositioning procedures.

In this review of 4487 patients the prevalence of residual dizziness (RD) was 43.0%.

Factors for residual dizziness included:

The researchers here concluded: “Despite successful treatment, nearly half of the BPPV patients developed residual dizziness (RD). RD seems to be a syndrome caused by multiple factors.”

“Despite successful treatment, nearly half of the BPPV patients developed residual dizziness. Residual seems to be a syndrome caused by multiple factors.”

Let’s focus on the above study and their findings that:

Cervical spine instability and recurrent benign paroxysmal positional vertigo

Compression on the brainstem and muscles spasms in the neck are characteristic of cervical spine instability. Not only can cervical spine instability cause dizziness and vertigo it can cause a myriad of symptoms.

This is an email we received, it has been edited for clarity:

“I woke up with sudden motion sickness and nausea after turning over in bed one morning. Upon fully standing and walking that same morning, experienced severe dizziness and room tilting, not spinning, as if a force was pushing me over. In the last months, have also experienced: severe headaches including pressure and tension, pins and needles or tingling, pain in face and teeth; difficulty sneezing; eye pain, eye strain, difficulty reading, light sensitivity; ear pain in and surrounding the ear, feelings of ear fullness, fluid in ears, ear ringing, sound sensitivity; tightness in throat, sometimes difficulty breathing; dizziness, feeling “off,” unsteady, wobbly, feeling like I might fall; depersonalization , derealization, disassociation, or general trouble of being present, being myself or comprehending reality. Recently experiencing more neck pain and irritation, neck muscles are tight and sore, and by the end of the day difficult to hold head up. These are all intermittent and unpredictable.”

The connection between cervical spine instability and recurrent benign paroxysmal positional vertigo is not without its controversies. An April 2022 paper in the  European archives of oto-rhino-laryngology (3) explored possible associations between cervical spine mobility, measured by cervical range of motion and a possible earlier onset of recurrent benign paroxysmal positional vertigo (BPPV), as well as an increased failure rate of canalith repositioning procedures.

A March 2022 study in the Ear, nose, and throat journal (4) also reviewed risk factors for Benign paroxysmal positional vertigo’s high recurrence rate. They found higher risk in patients who were:

Estrogens and Benign paroxysmal positional vertigo

Why the female gender? A February 2022 paper in the journal Current opinion in neurology (5) records that “recent work has identified a direct link between aberrant gonadal hormone levels and vestibular dysfunction. Benign paroxysmal positional vertigo research suggests that the disorder may be linked to the rapid decrease in estrogen, observed in menopausal women, which disrupts otoconial metabolism within the inner ear.”

A July 2022 paper in the journal Endocrine practice (6) writes of a high incidence of benign paroxysmal positional vertigo is reported in postmenopausal women, and the association between estradiol (E2) deficiency and the occurrence of BPPV has been made which may be a potential risk biomarker for postmenopausal women.

Now let’s center on problems identified as risk factors and found in the cervical spine

Cervical Spondylosis is an umbrella term used to describe degenerative changes in the cervical spine when there is no clear answer as to why you or a particular patient continues to suffer from any one of a long list of symptoms. Cervical Spondylosis has been implicated in problems of dizziness, vision problems, headaches, numbness or pins and needles sensation on one side of their face. Patients will tell us about fainting or nearly passing out from turning their head one way or another and problems we attribute to Vertebrobasilar insufficiency.

Cervical spondylosis is a non-specific degenerative process of the cervical spine, which can cause varying degrees of stenosis of both the central spinal canal and intervertebral neural foramina. Factors contributing to this narrowing include degenerative disc, osteophytes, and hypertrophy of the lamina, articular facets, ligamentum flavum, and posterior longitudinal ligament.
