Letter to the Editor: In Response to "Minimally Invasive Technique for Repairing CSF Leaks Due to Defects of Posterior Table of Frontal Sinus".

Abstract

We recently reviewed the article “Minimally Invasive Technique for Repairing CSF Leaks Due to Defects of Posterior Table of Frontal Sinus” by Bhavana et al.1 The authors present a technique of repairing traumatic cerebrospinal fluid (CSF) leaks of the posterior table through a frontal trephine and then use an endoscope to visualize and repair the defect using fat, cartilage, fascia lata, and fibrin glue as an alternative to the conventional approach of obliteration of the frontal sinus. They demonstrated that at a mean follow-up of 1 year, no patients had a CSF leak recurrence, and there was minimal morbidity (neuralgic pain and hypertrophic scar).
