Objective: To perform a systematic review of the diagnosis, treatment, and management of patients with otologic manifestations of eosinophilic granulomatosis with polyangiitis.
Databases reviewed: PubMed, Embase, Cochrane.
Methods: A systematic search for relevant published literature in PubMed, Cochrane Library, and EMBASE databases was done. Data was collected on demographics, otologic manifestations, specific diagnostic criteria fulfilled, common clinical, and imaging findings as well as medical and surgical treatments received.
Results: Fifteen articles encompassing 219 patients met inclusion criteria including 8 case reports and 7 case series. The mean age was 52.8 (range of 24-70). The most common otologic presenting symptoms were hearing loss (76%), otitis media with effusion (44%), vertigo (22%), tinnitus (21%), and chronic otitis media (20%). The most common diagnostic criteria observed in these patients were paranasal sinus abnormalities (75%), asthma (66%), and eosinophilia >10% (44%). The most common treatment was systemic steroids (66%), followed by surgery (52%), with myringotomy with tube insertion (M&T) (32%) and endoscopic sinus surgery (21%) being the most prevalent. Thirty-four percent of patients received an immunosuppressive agent. Successful treatments included systemic steroids (23%), surgical modalities (13%) with M&T being the most common (7%), topical nasal steroids (12%), and cyclophosphamide (10%).
Conclusion: Hearing loss and a middle ear effusion are the most common presenting otologic manifestations of eosinophilic granulomatosis with polyangiitis. Sinonasal disease was more prevalent in patients with otologic manifestations. Primary treatment consists of systemic steroids and immunomodulation. M&T, endoscopic sinus surgery, and local steroid administration can be adjunctive measures to alleviate local disease.Level of Evidence: Level 1.
