Voice problems are seldom reported in pollen @entity566 , although the @entity56 reaction involves the entire airways. The objective of this study was to investigate @entity409 during the pollen season in @entity1 with @entity2023 . Thirty @entity1 with verified birch pollen @entity566 and 30 controls were investigated twice, during the pollen season and outside the pollen season. Both times they scored @entity1576 , the latter with the validated questionnaire Voice Handicap Index (VHI), and performed standardized voice recordings. These recordings were analyzed in a controlled manner by a professional voice therapist. During the @entity566 season, @entity1 reported more @entity1576 compared with controls. Those with @entity409 scored their voice quality during springtime as 31 mm (95% confidence interval [CI] 20-42 mm), compared with 13 mm (95% CI 6-21 mm for @entity1 without @entity409 (P<0.01). Furthermore, the group with experienced @entity409 scored significantly higher on the VHI in the functional and physical domains and in the total VHI score. Although @entity1740 during the pollen season are rarely discussed, in @entity2023 the larynx may also be involved. These findings support that some @entity1 experience voice change, an experience which can be objectively confirmed.
