Abstract:
Objective: Background: Surgical management of cerebrospinal fluid (CSF) rhinorrhea can be done through a transcranial
approach or endoscopically using a transnasal approach. The endoscopic technology is relatively fresh in developing
countries. Keeping this in mind we conducted an audit of patients undergoing endoscopic repair of CSF leaks to review
their outcome in terms of recurrence and complications and compare them with the patients had transcranial repair. The
objective of the study is to review the management of patients who underwent repair of CSF rhinorrhea at Lyari General
Hospital, Aga Khan University Hospital and Memon Medical Institute Hospital – 10 years experience.
Study design: Cross-sectional observational study
Place and duration of Study: Lyari General Hospital, Aga Khan University Hospital and Memon Medical Institute Hospital,
from January 2005 to December 2014
Patients & methods: A review of patient charts having undergone surgical repair for CSF rhinorrhea in the last 10 years
at our institution was conducted. Thirty eight patients meeting the inclusion criteria of having undergone a surgical procedure
for the repair of CSF rhinorrhea with a minimum post operative follow up of 6 months were included in the study.
Results: Skull base defects were repaired with the help of minimally invasive transnasal endoscopic approach with a
success rate of 80% in comparison to transcranial repair success rate of 29%. Post-operative complications were seen in
only 10% of endoscopic group and 53% of transcranial group.
Conclusion: Although endoscopic management is associated with better outcomes there is room for improvement in the
approach in developing countries and training programs and detailed internal audits need to be conducted to improve the
situation to the level of developed countries.
