Özet:
Tinnitus is a common health complaint in the general population and many personal
and psychological factors play a role in the induction and exacerbation of it. Hence,
the aim of the present study was to assess, for the first time in the literature, whether
individuals’ biological rhythms differences, i.e. morningness vs. eveningness, have
an impact on the severity of tinnitus. We included 93 tinnitus patients who did not
have any underlying systemic or metabolic diseases. The morningness–eveningness
questionnaire was used to determine chronotypes and the Pittsburgh Sleep Quality
Index was used to assess subjective sleep quality. A Visual Analog Scale was used to
assess the severity of tinnitus, using a scale from 0 (no tinnitus) to 100 (most severe
tinnitus). The evening-type patients reported more severe tinnitus symptoms than
morning-types. These findings suggest that individual chronobiological factors affect
subjective estimates of tinnitus severity.
