A Case of Intracranial Complication after Endoscopic Marsupialization of Frontal Sinus Mucocele

Frontal sinus mucocele is a slow-growing benign lesion, which can expand large enough to compress the orbit and intracranial structures.When mucocele develops symptoms, the surgical procedure should be considered.Complete resection of mucocele is one surgical procedure and marsupialization, which makes ventilator pathway and preserves the inner wall of mucocele, is another way.A recent study announced that marsupialization shows similar or better results compared to external resection.We present a case of frontal sinus mucocele, which developed intracranial complication after successful marsupialization.
