Role of Acetazolamide in Traumatic CSF Rhinorrhea and Otorrhea: A Randomized Controlled Trial

Area of Science:

• Neurosurgery
• Traumatology

Background:

• Cerebrospinal fluid (CSF) leaks (rhinorrhea and otorrhea) following head trauma can lead to serious complications like meningitis.
• Acetazolamide is known to reduce CSF production, but its efficacy in managing traumatic CSF leaks is not well-established.
• Few formal studies exist on the role of acetazolamide in traumatic CSF leaks.

Purpose of the Study:

• To determine the role and effectiveness of acetazolamide in the management of traumatic cerebrospinal fluid (CSF) rhinorrhea and otorrhea.
• To evaluate if acetazolamide provides any advantage over conservative management in reducing the duration of CSF leaks.

Main Methods:

• A randomized controlled trial was conducted with 134 patients suffering from head injuries and CSF leaks.
• Patients were randomized into an intervention group (received acetazolamide) and a control group (did not receive acetazolamide).
• Comparative analysis was performed on 76 patients (44 in the intervention group, 32 in the control group) after excluding those requiring surgery or lumbar drains.

Main Results:

• The mean duration of CSF leak showed no statistically significant difference between the group that received acetazolamide and the control group (p = 0.344).
• The majority of patients were young adults (21-30 years) and predominantly male, with road traffic accidents being the most common cause (75%).
• Meningitis was the primary complication, with a higher incidence observed after lumbar drain insertion.

Conclusions:

• Adding acetazolamide to conservative management does not offer a significant advantage in treating traumatic cerebrospinal fluid (CSF) leaks.
• The routine use of acetazolamide for traumatic CSF leaks should be reconsidered based on these findings.
• Further research may be needed to explore alternative or refined treatment strategies for traumatic CSF leaks.
