CSF Leak Management for the General Practitioner

PROGRAM DESCRIPTION: Cerebrospinal Fluid (CSF) leaks occur when there is an abnormal communication between the intra-dural and extradural compartments. Diagnosis and management depend on the leak's location, etiology, and patient symptoms. Common causes include trauma, iatrogenic factors, tumors, and infections, while spontaneous and idiopathic cases are frequently seen by otolaryngologists and may be linked to comorbidities like obesity and idiopathic intracranial hypertension (IIH).

CSF leaks present a range of clinical manifestations that can complicate proper diagnosis. If not properly identified and treated, they can lead to serious complications such as meningitis. Key challenges in managing CSF leaks include:

-Heterogeneous clinical presentations that overlap with common otolaryngologic conditions.
-Intermittent symptoms with low-volume leaks.
-Selecting appropriate diagnostic tests.
-Localization of small dural fistulas for surgical management.
-Managing comorbid conditions like IIH.
-Limited knowledge of the latest treatment options.
This expert panel, consisting of anterior and lateral skull base surgeons and neurology, will guide practitioners through these challenges using a case-based format. The session will provide a practical framework for diagnosing and managing CSF leaks, including treatment options ranging from bed rest to surgical reconstruction, and discuss when to involve other specialists in a multidisciplinary team. Additionally we will discuss how to avoid common complications and provide updates on CSF + IIH guidelines and emerging treatments will also be covered.

Goals: Help general otolaryngologists identify, diagnose, and treat CSF leaks, focusing on the anterior and lateral skull base, with an emphasis on recurrence prevention and minimizing complications.

Target Audience: Comprehensive otolaryngologists encountering CSF leaks, especially those involving the anterior and lateral skull base, and those managing iatrogenic cases.

OUTCOME OBJECTIVE 1: Discuss the pathophysiology, epidemiology, and clinical presentation of CSF leaks

OUTCOME OBJECTIVE 2: Review work-up and initial management of anterior and lateral CSF leaks and the role of involving neurology

OUTCOME OBJECTIVE 3: Review standard and cutting-edge treatment options and discuss the timing of surgical intervention and specialist involvement

BACKGROUND STATEMENT: CSF leaks may be encountered by Otolaryngologists in a variety of presentations. Left untreated, leaks can be life-threatening. Moreover, IIH related CSF leaks are increasingly common. Nebulous presentations and diagnostic hurdles make this a challenging condition for ENTs to manage.

Comprehensive Otolaryngology Track Statement : Comprehensive ENTs often encounter CSF leaks, presenting diverse symptoms and causes, complicating diagnosis and treatment. Management requires holistic expertise from allergy, sleep apnea, rhinology, and otology.
