Long-term improvement of clinical symptoms after endoscopic sinus surgery in patients suffered from endocrine ophthalmopathy and orbital complications of rhinosinusitis.

Rhinosinusitis may cause serious complications, such as secondary orbital infections, resulting in expansion and erosion of process through the orbital wall. The aim is to evaluate long-term outcome of ESS in patients suffered from endocrine ophthalmopathy and orbital complications of rhinosinusitis. Thirteen patients with loss of vision, endocrine ophthalmopathy and orbital complication of rhinosinusitis were treated by ESS. Preoperative and postoperative vision was rated by best-corrected visual acuity (BCVA) testing. Nine (69%) have been reinvestigated after 6 years by ophthalmology examination and 10-point scale for assessment of clinical symptoms. The mean BCVA significantly increased after surgery comparing to results before surgery (0.84, 0.62; respectively) ( = .007). The mean values of 10-point scale for subjective assessment of symptoms 6 years after surgery were: headache 2.11, sinonasal pressure 1.72, subjective estimation of vision quality on the affected eye was 7.33 and olfaction 7.66. None of the patients developed impairment of vision loss in postoperative period. Long-term outcome of ESS showed decreased symptoms in patients who had endocrine ophthalmopathy and orbital complication of rhinosinusitis. ESS has numerous advantages for patients with orbital complication and vision loss comparing to conservative treatment and should be considered even in abscess absence.
