  • Title: Transnasal endoscopic removal of an extensive immature teratoma in a three-month-old child.
    Author: Voegels RL, Luxemberger W, Stammberger H.
    Journal: Ann Otol Rhinol Laryngol; 1998 Aug; 107(8):654-7. PubMed ID: 9716865.
    Abstract:
    The use of endoscopy in the paranasal sinuses has grown and diversified in the past few years. We present a case of an immature malignant teratoma originating from the sinuses, with intracranial extension to the middle and posterior fossae, that was managed and removed endoscopically. At the age of 2 months, the patient was hospitalized for respiratory instability. Diagnosis was made with biopsy, and chemotherapy was introduced. After 4 weeks, an endonasal endoscopic approach was performed, and a complete macroscopic removal of the tumor was achieved without complications. Follow-up for 10 months with magnetic resonance imaging and endoscopic examination has not revealed recurrence. In selected cases, the endonasal endoscopic technique may be a good alternative to the external approach, reducing the operative trauma and mortality.
