Orbital complications of functional endoscopic sinus surgery at King Hussein Medical Center

الملخص EN

Objectives: To evaluate major orbital complications of functional endoscopic sinus surgery (FESS) at King Hussein Medical center.

Methods: A retrospective study conducted at King Hussein Medical Center.

The medical records of patients who underwent functional endoscopic sinus surgery (FESS) for the last 5 years (between January 2012 and January 2017) were evaluated for the presence of any operative orbital complication, the results of orbital CT and MRI were obtained for such cases.

The Demographic data for the patients included in the study were reviewed in addition to method of surgery and type of orbital complication.

Any patient who was lost to follow up was excluded from the study.

The collected data were analyzed and compared with other studies conducted worldwide.

Results: Twelve patients out of 565 with a mean age of 42 years were found to have orbital complications.

Diplopia occurred in 5 patients as result of involvement of the medial rectus (4 patients) and inferior rectus muscle (one patient).

Orbital hemorrhage occurred in 3 patients, orbital cellulitis occurred in two patients and injury to the nasolacrimal drainage system occurred in two patients.

Computed Tomography and MRI were able to detect those complications in all patients.

Conclusion: Major orbital complications of functional endoscopic sinus surgery were infrequent at our hospital.

Only 12 complications (2.1%) were encountered in the study.

The most common complication was involvement of the extraocular muscle particularly the medial rectus.

Radio-imaging (MRI and CT) were very sensitive in detecting and defining orbital complication of functional endoscopic sinus surgery.
