[Evaluation of single-injection caruncular sub-Tenon's anesthesia].
BACKGROUND
Because of its complications, particularly globe perforation, retrobulbar injection has been progressively replaced by peribulbar anesthesia. However, with peribulbar anesthesia, the excessive rate of imperfect blockade requires supplemental injection. We have been performing local anesthesia using caruncular sub-Tenon single injection for many years. This technique is evaluated.


METHODS
A prospective study has been carried out on 183 eyes. Regional anesthesia was given by a caruncular sub-Tenon single injection. For each case, we studied akinesia, analgesia, pain before, during, and after surgery, the number of supplemental injections, eyeball orientation, and surgical conditions.


RESULTS
A total motor blockade was obtained in 157 cases (85.8%) and total lid akinesia in 176 patients (96.2%). Eight patients (4.4%) needed a second injection. During surgery, 10 patients complained of pain (5.5%). We found 27 eyes (14.7%) were divergent and 12 (6.5%) were convergent. Surgical conditions were good or very good in 90% of cases. No complications due to the injection (perforation or lesion of the eyeball or the optic nerve) were noted.


CONCLUSIONS
Single-injection caruncular sub-Tenon anesthesia is an alternative technique to classical peribulbar anesthesia. This technique is efficient, simple, easy to learn, reproducible, and seems to have a low rate of complications.
