Pulsatile Tinnitus --- The Accumulation of the Degree and Number of Risk
Factors Over Time
Abstract
Objectives: Pulsatile tinnitus (PT) is usually caused by vascular
pulsation, its pathogenic mechanism is still unclear. We conducted a
retrospective analysis of some patients diagnosed with PT, aiming to
provide clinical reference for future studies on PT. Design:
Retrospective study. Setting: Single institution. Participants: Surgical
treatment of PT in 52 patients. Methods: We counted basic
characteristics of all patients, analyzed the prognostic factors and the
treatment results, classified the etiology according to the imaging
findings. Results: The gender difference was statistically significant
in PT(2=44.308, P<0.001). The analysis results found a correlation
between duration of tinnitus and the prognosis of surgery
(P<0.05). we found 19 conditions can lead to PT. We reported
the first case in the world that the mirror man suffers from PT in our
study. Conclusions: Our study suggests that we attribute the cause of PT
to the superposition of the degree and number of risk factors over time.
The duration of tinnitus is related to prognosis. The hearing loss of PT
is mainly low frequency hearing loss. A total of 19 imaging conditions
can cause PT were found. PT caused by sigmoid sinus diverticulum had the
best surgical effect, while high jugular bulb had the worst. PT in
mirror person is reported for the first time, which provides clinical
reference for the diagnosis and treatment of PT in mirror person. At the
same time, we raised some new questions for the study of PT.
