Solitary Fibrous Tumour of the Sinonasal Cavity-Case Report of Endoscopic Resection Using Coblation

Solitary Fibrous Tumour of the Sinonasal Cavity – Case Report of Endoscopic Resection Using Coblation

Background: Solitary fibrous tumours (SFT) are extremely rare mesenchymal tumours. Surgery can be complicated by bleeding. This case describes the treatment by endoscopic approach, using novel operative strategies in a high-risk patient who was unable to have blood transfusion.
Case report: This 28 year old Caucasian female underwent trans-nasal surgery 8 years previously for a right sided sinonasal SFT. She re-presented on this occasion with recurrence of symptoms. Imaging revealed a part calcified mass at the base of anterior skull base with involvement of the right cribriform plate and with intra-cranial extension. Peri-operative embolization was found to be too hazardous.
Conclusions: To minimise surgical trauma, a trans-nasal endoscopic approach was undertaken, and macroscopic clearance was achieved primarily using coblation. This novel technique, which is as yet unreported in the literature for sinonasal SFT, was found to be a very effective means of ensuring haemostasis whilst maintaining an excellent field of view.
