[Recurrences of chemodectomas and hemangiomas of the ear: their diagnosis and treatment]. / Retsidivy khemodektom i gemangiom ukha, ikh diagnostika i lechenie.

Chemodectomas and hemangiomas of the ear account for 53.9% of overall occurrence of benign tumors of the ear. Recurrences are also a frequent finding. The leading treatment approach is surgical. The recurrences are managed surgically in combination with cryotherapy delivered by means of optic quantum generators. Follow-up of 45 patients established the maximal time of recurrence onset--10 years. Tumors which arise later should be considered as metachronous multifocal.
