The Role of Allergy in Phonation.

BACKGROUND

Allergies are among the most common chronic conditions worldwide affecting 10%-30% of adult individuals and 40% of children. Phonation can be affected by different allergic conditions in various ways. The role of allergy in phonation has been under-researched and poorly understood and the respective literature is poor. Several studies have investigated the role of certain allergic diseases in phonation. In this review, we tried to include all allergic conditions that can affect voice production.

METHODS

We conducted a bibliography review looking for allergic conditions that can affect phonation. Allergic asthma, allergic laryngitis, allergic rhinitis and sinusitis, oral allergy syndrome, and angioedema were included in our search.

RESULTS

The literature on the impact of allergy in phonation remains poor and many key questions concerning basic information for epidemiology, pathophysiology, and larynx pathology in allergic patients with phonation problems still remain unanswered.

CONCLUSIONS

The role of allergy in voice production remains underinvestigated and many basic questions still remain open. Further research is needed to improve our understanding for these very common conditions.
