Management of Frontal Sinus Cerebrospinal Fluid Leaks
Frontal sinus cerebrospinal fluid (CSF) leaks are technically challenging to repair, and there are a number of important considerations in evaluation and surgical management. The superior and lateral extents of the frontal recess are difficult to reach endoscopically, while the inferior and posterior portions of the frontal recess are challenging to reach from an external approach. In some cases, a combined approach may be warranted. An important guiding principle in repair is maintenance of frontal sinus patency, as an established outflow tract is necessary to prevent the formation of synechiae and mucoceles. In the following chapter, the anatomy and categorization of frontal sinus CSF leaks are discussed. Etiologies, diagnosis, and surgical approach for frontal sinus CSF leak are reviewed in detail.
