Deep orbital Sub-Q restylane (nonanimal stabilized hyaluronic acid) for orbital volume enhancement in sighted and anophthalmic orbits.

OBJECTIVE

To describe a new technique of injecting Restylane Sub-Q (Q-Med, Uppsala, Sweden) into the intraconal and extraconal posterior orbit.

METHODS

Retrospective review. Eight injections were performed in 5 patients using 2-mL Sub-Q in the intraconal and extraconal posterior orbit for orbital volume enhancement. Four injections were performed in sighted orbits and the remaining in anophthalmic orbits. The age range was 18 to 36 years; the follow-up time was 5 to 12 months.

RESULTS

Orbital volume enhancement was achieved in all cases with an improvement in upper eyelid sulcus and skin fold. Enophthalmos reduction was 2 mm per 2-mL injection. The procedure was well tolerated. One patient experienced a vasovagal episode lasting 3 hours and 1 patient had postoperative pain. No such episodes occurred after I began injecting local anesthesia before performing the Sub-Q injection. One patient required hyaluronidase for migrating gel, which caused lower eyelid swelling.

CONCLUSION

This small case series suggested the safety and tolerability of deep orbital Sub-Q. Injections are easily performed in the outpatient setting. The expected volume enhancement was achieved in all cases with no long-term adverse effects to date.
