Claude Bernard Horner’s-syndrome consists of the classic triad of blepharoptosis, miosis, and ipsilateral facial anhidrosis, associated with apparent enophthalmos. Specifically, in patients undergoing cervical discectomy, the incidence of Horner’s syndrome is uncommon, with reports indicating an incidence of 0.1 to 0.06%. Knowledge of the regional anatomy of the cervical sympathetic trunk is fundamental to limiting the iatrogenic syndrome of Horner; the subperiosteal dissection should be performed to facilitate the placement of the retractor under the longus colli muscle of the neck since lateral dissection of this muscle can cause sympathetic injury.

Palabras llave : iatrogenic Horner syndrome; cervical spine surgery; anterior approach.
