Proptosis is basically displacement of one or
both eye balls forwards and or side ways. Proptosis may be due to
increase in the volume of the orbital contents or compression of the
orbit from outside. An increase in the volume of the orbital
contents occur in Dysthyroid orbitopathy, inflammatory lesions of
the orbit and tumors of the orbit. The orbit is surrounded by the
paranasal sinuses and any expansible lesion of the sinuses will
result in proptosis. The commonest sinus causes for proptosis are
mucoceles, fungal sinusitis, fibrous dysplasias, cysts and tumours.
Today all sinus lesions can be tackled by Endoscopic Sinus Surgery.
The orbit is deliberately entered through nose, through its medial
wall and orbital lesions are removed through the nose.
At Sinus and Nose, a technique of retracting the
medial rectus is devised to get better exposure of the intraconal
structures and orbital apex. The removal of disease from these areas
becomes more precise and complete .
