Cross-sectional screening for inflammation in tinnitus with near-normal hearing.

Tinnitus is the perception of sound without an external stimulus. Recently, inflammation has been implicated in the pathophysiology of tinnitus. In tinnitus animal models, cytokine levels are increased throughout the whole auditory pathway, and microglia and astrocytes are activated.

Tinnitus: an underreported condition following microvascular decompression for hemifacial spasm.

Purpose: While hearing loss is a well-known condition following microvascular decompression (MVD) for hemifacial spasm (HFS), tinnitus is an underreported one. This study aims to identify prevalence, characteristics, severity, and predictors of tinnitus following MVD for HFS.

Methods: A single-center cohort of 55 HFS patients completed a questionnaire approximately 5 years following MVD.

Cerebellar Gray Matter Volume in Tinnitus.

Tinnitus is the perception of sound without an external source. The flocculus (FL) and paraflocculus (PFL), which are small lobules of the cerebellum, have recently been implicated in its pathophysiology. In a previous study, the volume of the (P)FL-complex correlated with tinnitus severity in patients that had undergone cerebellopontine angle (CPA) tumor removal.

The Role of Inflammation in Tinnitus: A Systematic Review and Meta-Analysis.

Subjective tinnitus is the perception of sound without the presence of an external source. Increasing evidence suggests that tinnitus is associated with inflammation. In this systematic review, the role of inflammation in subjective tinnitus was studied.

The cerebellar (para)flocculus: A review on its auditory function and a possible role in tinnitus.

The cerebellum is historically considered to be involved in motor control and motor learning. However, it is also a site of multimodal sensory and sensory-motor integration, implicated in auditory processing. The flocculus and paraflocculus are small lobes of the cerebellum, in humans located in the cerebellopontine angle.

The relation between flocculus volume and tinnitus after cerebellopontine angle tumor surgery.

Purpose: Chronic tinnitus is a common symptom after cerebellopontine angle (CPA) tumor removal. Sometimes, the tinnitus is gaze-modulated. In that case, patients can change the loudness or pitch of their tinnitus by ocular movements.
