Transcaruncular approach for the management of frontoethmoid mucoceles.

AIMS: To present transcaruncular medial orbitotomy as the preferred approach to manage frontoethmoid mucoceles.

METHODS

11 patients with frontoethmoid mucoceles received transcaruncular orbitotomy from 2000 to 2002 at the National Taiwan University Hospital. The incision was made through the caruncle to explore the medial wall periosteum. Then the periosteum was opened and extended to provide adequate surgical field exposure. Frontoethmoid mucoceles could be viewed and removed directly. A transnasal drainage tube was inserted before closure of the caruncle wound.

RESULTS

The mean follow up period was 12 (SD 9.1) months (range 1-26). Both functional recovery and cosmetic outcome were excellent. There was no recurrence of mucoceles. One patient complained of diplopia, which subsided after 2 months.

CONCLUSION

Transcaruncular orbitotomy provides a wide exposure and a safe access to the medial orbital extraperiosteal space. Furthermore, there is less damage to skin and muscle layer and less manipulation of other ocular adnexal structures, such as medial canthal tendon and lacrimal sac. It can be an excellent approach for the management of frontoethmoid mucoceles.
