Objective: To assess the feasibility and success of repair of transfrontal sinus cerebrospinal fluid (CSF) rhinorrhea through pterional transcranial extradural approach using endoscope. Summary of Background Data: Repair of CSF rhinorrhea has seen advancement with the evolution of endoscopic transnasal techniques. However, leaks from defect in the posterior wall of frontal sinus still remain a challenge for the skull base surgeons and requires conventional craniotomy more often. We describe a novel technique to repair these leaks by purely endoscopic pterional extradural (PEPE) approach thereby avoiding complications associated with conventional craniotomy and endoscopic transnasal approaches. Materials and Methods: Thirty-five patients with traumatic CSF rhinorrhea from the posterior wall of frontal sinus underwent repair with the present technique. They were followed up for 6\u201318 months and were evaluated for feasibility of procedure, recurrence of leak, and occurrence of the fresh neurological deficit. Results: Thirty-five patients underwent CSF rhinorrhea repair using the above technique. The procedure was accomplished in all patients without any intraoperative complications. There was no requirement of blood transfusion in any case. All patients had a cessation of CSF leak in the postoperative period, and there was no recurrence. There was no evidence of frontal lobe retraction injury in any of these patients, and no fresh neurological deficit was observed. Conclusion: This PEPE approach to repair CSF leak through the posterior wall of the frontal sinus is a novel technique in which we can avoid disadvantages associated with both conventional craniotomy as well as transnasal endoscopic approaches.<\/jats:p>","DOI":"10.4103\/0976-3147.176182","type":"journal-article","created":{"date-parts":[[2016,2,12]],"date-time":"2016-02-12T00:01:29Z","timestamp":1455235289000},"page":"310-313","source":"Crossref","is-referenced-by-count":3,"title":["Purely endoscopic pterional extradural approach: A novel technique for repair of cerebrospinal fluid rhinorrhea"],"prefix":"10.25259","volume":"07","author":[{"given":"Ajit Kumar","family":"Sinha","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Sir Ganga Ram Hospital, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sumit","family":"Goyal","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Sir Ganga Ram Hospital, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2019,9,25]]},"reference":[{"key":"key-10.4103\/0976-3147.176182-1","first-page":"274","volume-title":"Radiological study of primary spontaneous CSF rhinorrhoea","author":"Tolley","year":"1991","journal-title":"J Laryngol Otol"},{"key":"key-10.4103\/0976-3147.176182-2","first-page":"250","volume-title":"Cerebrospinal fluid fistula and endoscopic sinus surgery","author":"Stankiewicz","year":"1991","journal-title":"Laryngoscope"},{"key":"key-10.4103\/0976-3147.176182-3","first-page":"857","volume-title":"Endoscopic management of cerebrospinal fluid leaks and cephaloceles","author":"Mattox","year":"1990","journal-title":"Laryngoscope"},{"key":"key-10.4103\/0976-3147.176182-4","first-page":"1166","volume-title":"Transnasal endoscopic repair of cerebrospinal fluid rhinorrhea: A meta-analysis","author":"Hegazy","year":"2000","journal-title":"Laryngoscope"},{"key":"key-10.4103\/0976-3147.176182-5","first-page":"709","volume-title":"Endoscopic repair of frontal sinus cerebrospinal fluid leaks","author":"Woodworth","year":"2005","journal-title":"J Laryngol Otol"},{"key":"key-10.4103\/0976-3147.176182-6","first-page":"139","volume-title":"Unilateral endoscopic approach for repair of frontal sinus cerebrospinal fluid leak","author":"Roehm","year":"2011","journal-title":"Skull Base"},{"key":"key-10.4103\/0976-3147.176182-7","doi-asserted-by":"crossref","unstructured":"Marshall AH, Jones NS.
