Resection of Tumors Located in the Anterior Skull Base and Sellar Region Through the Supraorbital Keyhole Approach via a Forehead Wrinkle Incision: Modifications and Deficiencies

Endonasal versus supraorbital approach for anterior skull base meningiomas: Results and quality of life assessment from a single-surgeon cohort

OBJECTIVE

In this prospective non-randomized study we reported our experience related to planum sphenoidale (PS) and tuberculum sellae (TS) meningiomas in a similar cohort of patients operated via the endonasal or the supraorbital route. A comprehensive quality of life analysis has been performed.

METHODS

Being comparable in general features, between November 2017 to January 2020, a total of 20 patients with anterior skull base meningioma were included. Hence, 10 patients were treated using the supraorbital keyhole procedure (SO) while 10 patients received an endoscopic endonasal approach (EEA). Both surgical techniques were analyzed and compared. Quality of life has been analyzed with the SF-36 questionnaire.

RESULTS

Twenty patients were identified who underwent either EEA (n=10) or SO (n=10). The average extent of resection achieved was not significantly different between the 2 groups. Post-operatively, the EEA group demonstrated a longer hospital stay and bed days compared with SO patients as well as a longer surgical time. There was a significant rate of more CSF leakage after EEA then after SO (20% vs 0%, p=0,0491). The follow-up period resulted shorter in the SO group, with a slight increased recurrence rate. Overall, no differences in visual outcome were detected. There were no differences in terms of quality of life between the two groups in all the explored items.

CONCLUSIONS

In this single-center single-surgeon study of similarly sized and located PS and TS meningiomas, EEA showed longer hospital stays with higher degree of CSF leak compared with the SO group. Supraorbital craniotomy via eyebrow incision reported a comparable quality of life results, even if with a slightly higher percentage of recurrence and less follow-up.
