Background:
Vestibular dysfunction (resulting in dizziness and imbalance) is common in acute traumatic brain injury (aTBI). The most frequently diagnosed cause of peripheral vestibular dysfunction in aTBI is benign paroxysmal positional vertigo (BPPV). However, post-traumatic BPPV is often undiagnosed and left untreated in these patients.
Objectives:
To investigate clinical risk factors for BPPV in patients experiencing aTBI.
Methods:
Patients were recruited from three Major Trauma Centres in London. Logistic regression was used to derive the adjusted odds ratio (aOR) of diagnosed BPPV for sex, categorised age, severity of traumatic brain injury (TBI), and site of skull fracture.
Results:
166 patients with aTBI were included. Approximately a third (n = 55; 33.1 %) tested positive for BPPV. Compared to patients aged less than or equal to 40 years, those aged 41 to 64 years were more likely to experience BPPV (aOR=3.86; 95 % CI: 1.47 to 10.16; p = 0.006), as were those aged 65 years and above (4.41; 1.52 to 12.81; p = 0.006). Patients that experienced both facial and cranial skull fracture were more likely to experience BPPV than those that didn't have a skull fracture (23.64; 6.36 to 87.89; p < 0.001).
Conclusion:
The risk of post-traumatic BPPV increased with increasing age, plus in those with combined skull and facial fractures when compared to those without a skull fracture. We advocate routine BPPV screening of those with aTBI, especially in older adults and those with combined facial and skull fractures.
