Objective: Evaluate the risk of recurrent laryngeal nerve injury during thyroid gland surgery, while performing the extra-capsular dissection technique with exposure of the recurrent laryngeal nerves, without their continuous monitoring.
Study Design: Retrospective.
Material and Methods: We performed a retrospective research of 65 patient files submitted to thyroid surgery in the period between the 1st of April 2007 and the 30th of July 2007, in the Head and Neck Department of IPOFG- Lisbon.
Results: The total of vocal cord paralysis, including both temporary and permanent, was 3,77% of the exposed recurrent laryngeal nerve. Of those, 2,83% (which corresponds to 75% of total paralysis) were temporary paralysis, in comparison to 0,94% which were permanent.
Conclusion: The extra-capsular dissection technique of the thyroid gland, with exposure of the recurrent laryngeal nerve, dispensing with its monitoring, is by far the choice procedure to reduce the risk of postoperative nerve dysfunction, and we still manage to achieve the same recurrent laryngeal nerve injury rates described in current literature.References
