Bilateral Temporal Myofascial Flap for the Reconstruction of Frontal Sinus Defects.

ABSTRACT

BACKGROUND: A frontal sinus infection, following a transsinus skull base procedure, portends potentially life-threatening complications, making surgical revision mandatory in refractory infections. The authors describe the application of the bilateral temporal myofascial flap (BTMF) as a valuable option for frontal sinus reconstruction, when pericranial or galeal-frontalis myofascial flap (GFMF) is no longer available. METHODS: A microanatomic laboratory cadaver investigation was conducted to obtain anthropometric measurements. Surgical technique is described, and intraoperative images are provided. RESULTS: The surgical steps of this technique and the related intraoperative images are reported. One case illustration regarding frontal sinus reconstruction following a postoperative infection, as a complication after a transsinus procedure, is reported. CONCLUSION: The BTMF should be considered as a valuable option for frontal sinus reconstruction after transsinus skull base procedures when GFMF is not available.
