Objective:
The purpose of this investigation is to examine the prevalence of allergy in patients with primary dysphonia.
Methods:
The medical records of patients diagnosed with primary dysphonia and who underwent allergy testing during the period extending from June 2018-2020 were reviewed. Patients' demographics, laryngoscopic findings and allergy skin prick testing were analyzed.
Results:
A total of 22 patients were included. Eleven out of twenty-two patients (50%) tested positive to at least 2 allergens, and eight (36%) tested positive for at least 3 allergens. The most common allergens tested positive were D. Farinae for household inhalants, followed by Chenopodium, Russian thistle and weed mix for weeds. In patients with a positive allergy testing, the most common laryngeal findings included edema in 36%, followed by excess mucus and MTD in 18% of cases each.
Conclusion:
Allergy is common in patients presenting with primary dysphonia and non-specific laryngeal findings. Allergy testing should be part of the diagnostic work-up of affected patients.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
