Delayed Recurrent Post Cochlear Implantation Hydroma: A Four Patients Series

Objective: we report our series of late hydroma after cochlear implantation, this complication has not been widely reported in the literature. Method: retrospective study. Results: four children who had undergone a cochlear implantation aged between 3.2 and 5.3 years (median 4.5 years) were studied. The hydroma episode occurred 4 months to 3 years after cochlear implantation. Two patients had two recurrent episodes. No obvious etiological factors were found, including trauma or infection. No patient benefited from a fine needle aspiration or drainage, all the patients were treated with a broad-spectrum antibiotic with corticosteroid and a slightly compressive bandage with good results in all cases. Conclusion: Late-onset hydroma is a minor complication with no obvious etiology and good evolution and risk of recurrence, its management remains no codified due to the limited number of cases reported in the literature.
