Abstract
PURPOSE: The transantral approach to orbital decompression remains useful for the management of exophthalmos associated with dysthyroid orbitopathy. However, the risk of postoperative diplopia is a concern. Preservation of the anterior periorbita may help support the orbital contents and decrease the incidence of diplopia. METHODS: The medical records were reviewed of 15 consecutive patients who underwent 30 transantral orbital decompressions for proptosis associated with dysthyroid orbitopathy. The procedures were completed in standard fashion, including removal of the inferomedial bony strut between the medial orbital wall and the floor. However, stripping of the periorbita was only done posteriorly; the anterior 10 to 15 mm of periorbita were left intact. RESULTS: Six patients had preoperative diplopia that persisted after decompression. Of the nine patients without diplopia preoperatively, none developed diplopia. Proptosis was reduced a mean of 3.5 +/- 2.6 mm. CONCLUSIONS: Preservation of the anterior periorbita during transantral orbital decompression reduces the risk of postoperative diplopia. An adequate reduction in proptosis is also achieved.
