A new millimeter muscle hook for strabismus surgery

ABSTRACT

Objective:

To evaluate a new type of muscle hook (Felício's millimeter hook) and its effectiveness in strabismus surgeries.

Methods:

Seeking an independent approach, with minimal assistance from the assistant, the new instrument was used in retrocession and resection surgeries, to compare its efficacy and safety with the traditional technique.

Results:

14 patients participated in the study, divided into two groups. The group who underwent surgery with the traditional technique had a mean age of 14.7 years and the group using the new hook, 17 years. Both groups obtained a similar reduction in initial strabismus, with an average of 87.84% in the traditional group and 93.04% with the new hook, but without statistically significant difference (p=0.274).

Conclusion:

Felicio's millimeter hook proved to be a useful option for the surgeon in performing strabismus surgery with a reduction in the importance of the assistant, in a safe and reproducible way.
