Incidence of infraorbital hypesthesia and sinusitis after orbital decompression for thyroid-related orbitopathy: a comparison of surgical techniques.
OBJECTIVE
To compare the incidence of postoperative infraorbital (V2) hypesthesia and sinusitis between transantral/Caldwell-Luc and transconjunctival orbital decompression for thyroid-related orbitopathy.


METHODS
A retrospective review of all orbital decompressions from January 1994 to January 2001 performed by one surgeon was done. Seventy-eight patients (133 orbits) with thyroid-related orbitopathy underwent orbital decompression for compressive optic neuropathy, exposure keratopathy, or uncontrolled intraocular pressure. Main outcome measures were the presence of V2 hypesthesia and sinusitis determined at 3 postoperative evaluations (1 to 2 weeks, 1 to 3 months, 3 to 6 months).


RESULTS
The incidence of V2 hypesthesia in the transconjunctival group declined from 29.2% (19/65) to 6.1% (4/65), whereas the incidence of V2 hypesthesia in the transantral/Caldwell-Luc group decreased from 68.2% (43/63) to 46% (29/63) over the postoperative course. The rate of sinusitis in the transconjunctival group stayed constant at 6.1% (4/65) at early and late postoperative visits, whereas the transantral group rate of sinusitis declined from 33.3% (21/63) to 9.5% (6/63).


CONCLUSIONS
Transconjunctival orbital decompression results in a statistically significant decrease of early and late postoperative infraorbital hypesthesia and early postoperative sinusitis when compared with the transantral approach.
