Assessing the Impact of Allergic Rhinitis on Eustachian Tube Function (CODE- T0022)

Introduction: The Eustachian tube plays a vital role in preserving middle ear health by equalizing pressure, protecting against harmful external sounds and pathogens, and facilitating the clearance of secretions. Allergic rhinitis (AR), a common upper airway disorder, may impact Eustachian tube function (ETF), potentially leading to middle ear dysfunction. This study explores the interplay between AR and ETF to enhance understanding and inform effective management strategies.

Aim and Objectives:

Aim:

• To evaluate the Eustachian tube function in patients with Allergic Rhinitis.

Objectives:

• To assess the effect of Allergic Rhinitis on Eustachian tube function.
• To determine the influence of Allergic Rhinitis severity on Eustachian tube function.

Methods: This cross-sectional study was conducted at the Dr. KNS Memorial Institute of Medical Sciences from August 2022 to March 2024. Seventy-five patients aged 25–65 years diagnosed with AR were included. Data were collected using clinical examinations, tympanometry, serum IgE level assessment, and questionnaire-based history taking.

Results: A significant association between AR and Eustachian tube dysfunction (ETD) was observed (chi-square: 42.26, p<0.001). Females exhibited a higher prevalence of middle ear dysfunction and experienced longer annual symptom durations than males. Antihistamine use correlated with reduced symptom severity and improved quality of life, as measured by lower Rhinitis Quality of Life Questionnaire (RQLQ) scores. Younger adults (30–40 years) were more susceptible to AR-related ETD, highlighting the importance of early diagnosis and intervention.

Conclusion: AR significantly impacts ETF, particularly in females and young adults. This underscores the need for early intervention, routine screening, and tailored treatment approaches. Future longitudinal studies with larger cohorts are necessary to validate findings and optimize management protocols, ultimately improving care for patients with AR-related ETD.
