Endoscopic Sinus Surgery; Orbital Complications: a Case Series

.. Background: Endoscopic sinus surgery has become a preferred modality for management of various nasal and sinus disorders. Orbital complications, though rare, are reported amongst patients undergoing ESS. Study Design: Case series. Methods: A retrospective review was undertaken of four cases of orbital complications during endoscopic sinus surgery. Results: Two patients suffered from periorbital haematoma and subconjunctival haemorrhage. One patient developed subcutaneous emphysema and numbness of lower eyelid and cheek. One patient got oedema of lower eyelid. Conclusion: Ophthalmic complications occurring during ESS should be timely and properly addressed. By having sound knowledge of anatomy of nose, paranasal sinuses and orbit and detailed preoperative assessment, chances of orbital complications can be lessened.
