  • Title: Endoscopic Endonasal Reconstruction Using a Pedicled Middle Turbinate Flap for Spontaneous Cerebrospinal Fluid Rhinorrhea.
    Author: Takahara K, Ueda R, Toda M.
    Journal: J Craniofac Surg; 2022 May 01; 33(3):e318-e320. PubMed ID: 35727659.
    Abstract:
    Although endoscopic skull-base reconstruction protocols to reduce cerebrospinal fluid (CSF) leakage are reported, the most effective management strategies have not been determined. We describe the successful repair of a spontaneous CSF leak using a vascularized middle turbinate flap (MTF) via an endonasal endoscopic approach and also discuss the effective reconstruction with other available pedicled flaps. An 11-year-old girl had a 5-month history of intermittent CSF rhinorrhea. Endoscopic endonasal skull base reconstruction was performed using the pedicled MTF technique, which sufficiently covered the unilateral cribriform plate and ethmoidal fovea including suspicious leakage site. Middle turbinate flaps may be good for repairing spontaneous CSF leaks, which commonly have small, low-flow CSF fistulas around a cribriform plate. As spontaneous CSF leaks are known to have a higher recurrence rate, MTF may be advantageous because more of the normal structures are retained.
