Endonasal technique for orbital decompression surgery in a patient with Graves’ exophthalmopathy

Abstract

Female, 29, former smoker, diagnosed in September 2012 with Graves’ disease and rapid presentation of bilateral exophthalmos. In the ophthalmologic evaluation, it presented preserved motility, proptosis and upper fat sac in OA with retraction of PPSS and PPII and exophthalmetry in OD of 26 mm, and in OE of 24 mm. In May 2014, he performed the mapping of the retina that showed scars of chorioretinitis in both eyes and computerized campimetry, presenting a nasal step in OD, superior contraction, central-inferior depression. In June 2016, he underwent orbital decompression surgery of the medial and inferior bilateral walls by endoscopic approach using the Karl Storz nasal endoscope at 30 degrees of optics. The surgical approach of Graves’ ophthalmopathy should be used in the cicatricial phase except in cases with risk of loss of vision. Before performed by external access, orbital decompression can now be performed endoscopically, with minimal invasiveness and allows the removal of the inferior wall and Without external incisions. It is a safe procedure for the treatment of dysthyroidal orbitopathy, associated with lower morbidity, in which lesions are avoided in the nasolacrimal, nasofrontal, or infraorbital ducts and it is possible to reduce proptosis between 3 and 4 mm. The benefits of decompression are related to Improvement of visual acuity, besides the aesthetic result. The continuation of the surgical treatment will be performed by correction of palpebral retraction followed by blepharoplasty.
