    Author: Valencia-Sanchez BA, Zhou S, Patel VA, Gomez G, Ference E.
    Journal: Ear Nose Throat J; 2023 Sep; 102(9_suppl):40S-42S. PubMed ID: 37394967.
    Abstract:
    Background: Spontaneous cerebrospinal fluid (CSF) rhinorrhea in the pediatric population is an exceedingly rare condition that occurs when the dura mater is breached, resulting in CSF drainage from the subarachnoid space into surrounding sinonasal tissue. Objective: This work delineates a step-by-step surgical approach to visually demonstrate the feasibility of an uninarial endoscopic endonasal approach for pediatric spontaneous CSF leak repair. Postoperative Outcome: A 2-year-old male with a 6-month history of clear rhinorrhea, intermittent headaches, and a previous episode of bacterial meningitis was evaluated as an inpatient consultation. Computed tomography cisternography revealed active CSF extravasation at the right sphenoid sinus roof. An endoscopic endonasal approach was performed including a complete sphenoethmoidectomy plus middle turbinectomy to provide access to the skull base defect. Once identified, a middle turbinate free mucosal graft was placed for cranial base reconstruction given the child's young agre. Sinonasal debridement 3 weeks following surgery under anesthesia revealed an intact viable graft with no evidence of CSF leak. There was no evidence of CSF leak recurrence or complications 1 year following surgery. Conclusion: The uninarial endoscopic endonasal approach is a safe and effective option for the surgical management of spontaneous CSF leak rhinorrhea in the pediatric population.
