[Orbital congenital nevi: Principles of treatment about 51 cases].

INTRODUCTION

The incidence of congenital nevi is one over 20,000 newborns per year, 14 % of them are located in the head and neck area. Nevi of the orbital region are particularly difficult to handle on the aesthetic and functional side. The objectives of this study were to conduct an analysis of different clinical presentations of congenital nevi of the eyelid orbital region in children to establish a treatment algorithm.

MATERIEL AND METHODS

We realised a bi-centric retrospective study including 51 children with orbito-palpebral congenital nevi. We analysed the different clinical presentations, their treatments and their results.

RESULTS

Nineteen underwent direct suture excision; three a total skin graft; 15 a combination of treatments, among them four underwent tissular expansion and 14 patients were not operated and clinically followed-up. The average follow-up time was 6.6 years. In 33 cases residual nevic area was still present. The postoperative sequelae were: dyschromia (n=17), anatomical deformation of the eye (n=10), nevi outbreaks (n=8), internal canthus deformation (n=5) and ectropion (n=1).

CONCLUSION

The results of our study show that therapeutic abstention is preferred when the aesthetic wrong is accepted by the patient and when there is not a higher risk of malignant degeneration. In order to minimise the risk of postoperative sequelae, we propose a therapeutic algorithm for the management of congenital orbital nevi.
