Introduction:
The purpose of the present study was to determine the possible effect of allergic rhinitis (AR) on voice change in children with acoustic analysis and Turkish children's voice handicap index-10 (TR-CVHI-10).
Methods:
This is a case-control study. Forty-one children with AR, and a positive skin prick test, as well as 39 children of controls who had produced a negative skin prick test and lacked a history of allergic disease, were selected for the study. Each assessment included recordings for the purposes of acoustic voice analysis (fundamental frequency [f0], jitter %, shimmer %, and harmonics-to-noise ratio (HNR)), and aerodynamic analysis (maximum phonation time (MPT) and s/z ratio). All participants completed TR-CVHI-10.
Results:
The mean TR-CVHI-10 score of the AR group was significantly higher than the control group (p = 0.013). No difference was observed between the AR and control groups in terms of jitter, shimmer, HNR, and MPT values and s/z ratio (p > 0.05). Conversely, the f0 value was more pronounced in controls (270.9 ± 60.3 Hz) than in the AR group (237.7 ± 54.3 Hz) (p = 0.012).
Conclusion:
The study's results revealed that AR can have an effect on fundamental frequency and voice quality in children. The diagnostic process should include AR as a potential cause of voice disorders in children.

Larynx
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,...
Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
Asthma-I: Introduction
Chronic Pharyngitis
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,...
