Combined endoscopy-assisted cranionasal approach for resection of infantile myofibromatosis of the ethmoid and anterior skull base. Case report.
The advent and widespread development of endonasal endoscopic techniques have recently expanded the frontiers of skull base surgery. The reduced invasiveness, wider and adjustable visualization of the operative field, and lack of postoperative cosmetic defects are well-known advantages of the endonasal endoscopic approaches compared with traditional surgical exposures both in adults and in children. The need to avoid disruption of facial growth centers and permanent tooth roots represents a further special consideration in favor of these endoscopic techniques in children. The authors report on a case of solitary myofibroma involving the ethmoid, mesial orbits, and anterior skull base with intracranial intradural expansion in a 17-month-old girl. The occurrence of such proliferative disease along the skull base is exceedingly rare. The tumor was successfully excised via an endoscopy-assisted cranionasal approach in which a transcranial microsurgical exposure was combined with endonasal endoscopic access to ensure a radical resection and optimize skull base reconstruction. To the authors' knowledge, the patient in this case is the youngest reported patient in the literature who has undergone treatment with this surgical strategy. The outcome in this patient underscores the feasibility and safety of endoscopic endonasal surgery even in toddlers and early childhood.
