Endonasal endoscopic orbital decompression – introducing the five steps technique

OBJECTIVE. To describe and evaluate the five- step approach for endonasal endoscopic orbital decompression. STuDy DESIGN. A retrospective noncomparative case series. METHODS. The distinctive five-steps technique for endonasal endoscopic orbital decompression was performed on 97 patients suffering from dysthyroid orbitopathy over the period of eleven years (2000-2010). RESuLTS. The method resulted in significant benefit for patient’s visual acuity, proptosis, intraocular pressure, retraction of the eyelids and exposure keratitis. New-onset diplopia developed in 23 patients (23.7%). It persisted in 94.6% of patients with preoperative diplopia while 22.6% of patients experienced postoperative relief of diplopia. CONCLuSIONS. Endonasal endoscopic orbital decompression is effective and safe procedure that improves vision, decreases proptosis and intraocular pressure with favorable cosmetic results in most patients. Post-decompression strabismus and diplopia are successfully managed by either eye muscle surgery or application of prisms.
