Abstract / Summary
Background: Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), represents a chronic immune-mediated disorder frequently associated with extraintestinal manifestations. While musculoskeletal, dermatologic, and ocular complications are well recognized, ear, nose, and throat (ENT) involvement remains underrecognized despite its potential morbidity. Objective: To systematically evaluate the spectrum of ENT manifestations in IBD, focusing on clinical presentation, diagnostic approaches, and outcomes. Methods: A systematic literature search was conducted in PubMed and Scopus in accordance with PRISMA 2020 guidelines. Eligible studies included English-language human studies (2015-2026) reporting ENT manifestations in UC or CD. Following screening, 23 studies were included in the qualitative synthesis. Extracted data comprised study design, IBD subtype, patient demographics, ENT manifestations, diagnostic methods, and clinical outcomes. Results: The majority of studies consisted of case reports and small observational series. Sensorineural hearing loss (SNHL) was the most frequently reported manifestation in both adult and pediatric populations, with evidence suggesting immune-mediated mechanisms and variable responsiveness to corticosteroids. Nasal involvement included pyoderma gangrenosum, pyoderma vegetans, and aseptic nasal septal abscess, occasionally resulting in severe structural complications such as saddle-nose deformity. Laryngeal and airway involvement included dysphonia, tracheitis, and rare but potentially life-threatening inflammatory airway disease. Additional findings included associations with chronic rhinosinusitis. Diagnosis relied on audiometry, imaging, endoscopy, and histopathology. Systemic corticosteroids were frequently effective; however, delayed recognition may lead to irreversible sequelae. Conclusions: ENT manifestations in IBD constitute a clinically heterogeneous but important group of extraintestinal complications. Increased awareness of ENT manifestations may support earlier diagnosis and multidisciplinary management of IBD, potentially reducing irreversible complications.
