AB0642 Otolaryngeal Manifestations of Behçet's Disease in a Northern European Population

Background The Otolaryngologic-related manifestations of Behcet9s Disease (BD), though previously described, have been less thoroughly explored in the literature, particularly in a Northern European population. These manifestations are said to be relatively rare and include hearing loss, pharyngeal and laryngeal ulceration and nasal mucosal involvement. Objectives The aim of this study was to undertake an assessment of a cohort of BD patients, documenting any laryngeal manifestations or evidence of reduced hearing. Methods Patients meeting the International Study Group for Behcet9s Disease (ISGBD) or the International Criteria for Behcet9s Disease (ICBD) criteria for diagnosis were identified from an institutional database. Patients underwent assessment with an otolaryngologist, including flexible laryngoscopy. Intra-oral, pharyngeal and laryngeal manifestations of BD were documented and characterised. Patients underwent hearing assessment with pure-tone audiometry. Results Fifteen BD patients were identified (4 male, 11 female; median age 36 years). 60% (n=9) showed evidence of disease on examination and flexible laryngoscopy. 33% (n=5) including two asymptomatic patients showed structural laryngeal changes related to BD. 13% (n=2) demonstrated bilateral, symmetrical sensorineural hearing loss. One patient warranted consideration for tracheotomy. Conclusions Our cohort of BD patients demonstrate significant structural laryngeal changes, which appear to be more common than was previously thought. Therefore, raised awareness of the risk of laryngeal pathology in BD patients, including potential risk for later airway compromise, even in the absence of overt clinical symptomatology, and early screening may result in earlier diagnosis and treatment. Rheumatologists and Otolaryngologists should consider closer multi-disciplinary co-operation in the management and follow up of patients with BD. References Webb CJ, Moots RJ, Swift AC.
