Complications of transpalpebral bony orbital decompression for dysthyroid orbitopathy

Introduction : Complications of bony orbital decompression (BOD) are rather unrerorted and often neglected. The aim of this study was to assess the ri sks of this surgery. Material and methods : 44 patients (76 orbits) were studied. There were 19 malignant orbitopathies and 57 cosmetic rehabilitations. All side-effects a nd true complications were reported. A questionnary was send to the patient and to his ophthalmologist. Results: Infra-orbital hypoesthesia, oculomotor disorders, entropion, chang es of lid position were the most: frequent complications. A case of hypoglo bus, a case of lacrimal stenosis, a case of decreased visual acuity were re ported. Discussion : Side-effects of BOD are frequent. Higher rates are even found in the litterature. These effects tend to decrease spontaneously or can be treated by adequate medical or surgical care. Some measures are proposed to perform surgery safer. Conclusion : More precise information should be given to the patients befor e surgery and a better prevention can be afforded.
