| Abstract: | We report a case during which a new method of reconstruction for a nasopharyngeal and skull base defect was successfully performed. A 45‐year‐old female with granulomatosis with polyangiitis presented with computed tomography (CT) findings demonstrative of chronic clival and cervical spine osteomyelitis secondary to nasopharyngeal destruction. The posterior nasopharyngeal defect, evident as a wide area of mucosal erosion exposing the clivus centrally, was successfully reconstructed with an anterior serratus muscle‐free tissue transfer via both transcervical and endoscopic transnasal approaches utilizing a laparoscopic fixation device, a previously unreported method for free flap inset, to secure the free flap. The patient tolerated this well and no major complications were encountered. At 2‐year follow‐up, the patient was without signs of cerebrospinal fluid leak or sequelae of infectious complications, including meningitis and osteomyelitis. A combined transcervical and endoscopic transnasal approach using a laparoscopic fixation device for free flap inset can be an effective method to reconstruct posterior nasopharyngeal defects in those patients whom local reconstructive options are not available. |
