The results of orbital decompression for thyroid eye disease are presented in a cohort of 33 patients. It was performed by an external Patterson approach in 21 individuals and in 13 by an endonasal endoscopic approach. The endoscopic approach was entirely comparable in respect of improvement in axial proptosis, giving a mean improvement of 4.4 mm as compared with a mean of 3.8 mm for the external approach, and produced a demonstrable improvement in visual acuity and perception of colour in three individuals, where this was compromised, and was associated with fewer complications.
