BACKGROUND: To validate the repair of frontal sinus cerebrospinal fluid (CSF) leaks with preservation of frontal sinus drainage pathway (FSDP), independently of the approach used, and to establish the indications and limits of the endoscopic approach. METHODS: A retrospective evaluation of patients undergoing surgery for frontal sinus CSF leaks was performed. Demographics, indications for both endoscopic/combined endoscopic and open approaches, complications, methods for maintaining FSDP, and perioperative outcomes were examined. RESULTS: Fifty-three patients (average age 45 years) with frontal sinus CSF leaks were treated surgically from 2000 to 2018. All CSF leak repairs were successful at the 1st attempt with a mean follow-up of 76.8 months (range 4-227 months). Etiology was spontaneous (14), traumatic (26), and iatrogenic (13). In 17 patients, a purely endoscopic approach was performed, while an endoscopic endonasal orbital transposition procedure was added in 4 out of this group. In 23 patients, a combined endoscopic and osteoplastic procedure was employed, while in 13 patients a combined craniotomy and endoscopic procedure was performed. All frontal sinuses remained patent except for 2 cranialization patients. CONCLUSION: With contemporary endoscopic instrumentation and techniques, endoscopic closure of frontal sinus CSF leaks even in the far superolateral wall is feasible in selected patients. However, the surgeon should consider the option of combining an external approach when required. Preserving the FSDP should be the main aim regardless of the approach.

Abstract

BACKGROUND: To validate the repair of frontal sinus cerebrospinal fluid (CSF) leaks with preservation of frontal sinus drainage pathway (FSDP), independently of the approach used, and to establish the indications and limits of the endoscopic approach. METHODS: A retrospective evaluation of patients undergoing surgery for frontal sinus CSF leaks was performed. Demographics, indications for both endoscopic/combined endoscopic and open approaches, complications, methods for maintaining FSDP, and perioperative outcomes were examined. RESULTS: Fifty-three patients (average age 45 years) with frontal sinus CSF leaks were treated surgically from 2000 to 2018. All CSF leak repairs were successful at the 1st attempt with a mean follow-up of 76.8 months (range 4-227 months). Etiology was spontaneous (14), traumatic (26), and iatrogenic (13). In 17 patients, a purely endoscopic approach was performed, while an endoscopic endonasal orbital transposition procedure was added in 4 out of this group. In 23 patients, a combined endoscopic and osteoplastic procedure was employed, while in 13 patients a combined craniotomy and endoscopic procedure was performed. All frontal sinuses remained patent except for 2 cranialization patients. CONCLUSION: With contemporary endoscopic instrumentation and techniques, endoscopic closure of frontal sinus CSF leaks even in the far superolateral wall is feasible in selected patients. However, the surgeon should consider the option of combining an external approach when required. Preserving the FSDP should be the main aim regardless of the approach.
