ABSTRACT

Objective: To determine the efficacy of subtenonian botulinum toxin in the treatment of sixth cranial nerve palsy.
Methods: 20 files, from January 2004 to November 2006, of patients with sixth cranial nerve palsy of any etiology were analyzed. Patients were treated with subtenonian injection of botulinum toxin in the medial rectus. Data of patients regarding age, affected muscle, primary position, amount of duction limitation, presence of diplopia after and before treatment, and number of applicated doses were analyzed.
Results: The average age was 58.15 years (13 to 87 years) ten patients (50%) were male and ten (50%) were female. Twenty five doses were applied, 20 (75%) as first application and 5 (15%) as second due to absence of improvement. All patients (100%) had limitation of duction. After the treatment 15 patients (75%) had no limitation. Before the application none of the patients had ocular alignment, at the end of the treatment 18 patients (90%) obtained it.
Conclusions: The use of subtenonian botulinum toxin brings a fast and effective improvement in the treatment of sixth cranial nerve palsy of any etiology.
