Background: Hibernomas are rare, benign tumors of brown adipose tissue uncommonly found in the head and neck. Methods: A review of the English literature was conducted. We present a series of 2 laryngeal hibernomas treated with transoral laser microsurgical resection at a tertiary referral center over a period of 18 years. Results: Only 2 cases of laryngeal hibernoma have been previously described in the literature. Two additional cases were encountered at our institution. Preoperative imaging demonstrated a well-circumscribed neoplasm with fat density compatible with lipoma, but internal heterogeneity and vascularity seen in the context of liposarcoma. Transoral laser microsurgical resection was successfully performed in each case. Conclusions: Despite unique radiographic features, hibernomas are difficult to distinguish from well-differentiated liposarcoma and lipoma variants without pathologic correlation. Complete surgical resection is indicated. In our experience, transoral laser microsurgical excision of laryngeal hibernomas is a safe, effective treatment modality with little associated morbidity.
