3D Slicer reconstruction combined with neuroendoscopic keyhole approach for the treatment of cerebrospinal fluid rhinorrhea：2 cases report and literature review.

BACKGROUND AND IMPORTANCE

Explore the techniques, advantages and disadvantages of 3D Slicer reconstruction combined with transcranial neuroendoscopy in cerebrospinal fluid rhinorrhea surgery.

CLINICAL PRESENTATION

We collected complete clinical data of two patients with cerebrospinal fluid rhinorrhea who underwent minimally invasive surgery using 3D Slicer reconstruction combined with transcranial neuroendoscopy through the supraorbital eyebrow arch keyhole approach in our hospital from June 2022 to May 2023. The patients were one male and one female, aged 50 and 63 years old. At the same time, a retrospective summary of relevant literature at home and abroad in recent years was conducted. 1 case had spontaneous cerebrospinal fluid rhinorrhea with secondary cribriform plate lesion, and the other 1 case had traumatic cerebrospinal fluid rhinorrhea. Both 2 patients were ineffective after long-term conservative treatment, and ultimately recovered after detailed preoperative evaluation and preparation and surgical treatment.

CONCLUSION

Cerebrospinal fluid rhinorrhea is a challenging disease in neurosurgery, and improper management can lead to serious complications such as meningitis. Our team used 3D Slicer reconstruction combined with transcranial endoscopic minimally invasive keyhole surgery to treat cerebrospinal fluid rhinorrhea, achieving good results, proving that this combined technology has certain advantages and is a new surgical technique worth promoting. However, the widespread application and promotion of this technology in anterior skull base surgery still require comprehensive and reliable prospective clinical studies to test.
