ABSTRACT
Objective To explore the effect of exposure of the recurrent laryngcal nerve(RLN) in prevention of RLN injury during thyorid surgery.Methods The clinical data of 810 cases of thyroid operation in which the RLN was exposed in 252 cases(group A) and was unexposed in 558 cases(group B) were analyzed.Results Although the extent of thyroid resection was greater in group A than in group B,the rate of RLN injury in group A(1.19 %) was significantly lower than that of group B(3.05 %,P
ABSTRACT
Objective To retrospectively evaluate the necessity to dissect the recurrent laryngeal nerve in operation of thyroid gland.Methods From Jan 2004 to Jan 2009,there were 512 patients in our hospital who underwent operation of thyroid gland,and they were divided into two groups aecording to whether or not the recurrent laryngeal nerve was dissected during the operation.The rate of injury of recurrent laryngeal nerve between the two groups was compared.Results Among the 189 cases in dissection of recurrent laryngeal nerve group,3 cases(1.59%) had hoarseness after operation,and in the 323 cases without dissection of the recurrent laryngeal nerve group,5 cases(1.55%) had hoarseness after operation,but the difference was not significant(1.59% vs.1.55%).However,in the high risk cases between the two groups,the difference was significant(1.02% vs.3.95%).Conclusions Whether oe not to dissect the recurrent laryngeal nerve should be decided by the specific circumstances.For most benign lesions,one should,if possible,not expose the recurrent laryngeal nerve;but for large thyroid neoplasms,second or multiple operations and thyroid cancer,exposure of recurrent laryngeal nerve is necessary.
ABSTRACT
Objective To study the method and effect of exposure the recurrent laryngeal nerve(RLN) in preventing the damage of RLN in thyroid surgery. Methods One thousand and ten sides total and(or) subtotal thyroidectomies were operated on 574 cases with RLN exposure in our hospital in recent 9 years. Results The RLN injury rate was 0.3% in this series.Of them, permanent RLN injury occurred in 2 cases and temporary injury in 1. Conclusions The exposure of RLN can greatly decrease the nerve injure in thyroid surgery, especially in total lobectomy. The dissection of RLN must followed the principle of RLN exposure . RLN should be dissected around the inferior thyroid artery first, if the RLN is difficult to be found,then dissecting around the thyroid cartilage, or finding the cervical vagus inside of carotid sheath to find RLN should be done.
ABSTRACT
Objective To study the effect of exposure of recurrent laryngeal nerve(RLN) in prevention of RLN injury during thyroid surgery under general anesthesia.Methods The clinical data of 389 patients who underwent thyroid operations under general anesthesia were retrospectively reviewed.The RLN was exposed in 163 cases and was not exposed in 226 cases.Results Two cases(1.10%) suffered from temporary RLN injury in exposure group and 12 cases(5.30%) suffered from RLN injury in non-exposure group(temporary nerve injury in 7 cases and permanent nerve injury in 5 cases)(P
ABSTRACT
Objective To explore the relation of recurrent laryngeal nerve damage with the mode of surgery and exposure of the nerve in thyroidectomies.Methods We retrospectively reviewed the clinical data of 2142 thyroidectomy patients.There were 540 unilateral and 1602 bilateral procedures with 3744 nerves at risk of injury.Among them,1986 nerves were explored and indentified,and 1758 nerves were not exposed.Results The overall incidence of recurrent laryngeal nerve injury was 0.93%(20/2142),and with an incidence of 0.37%(8/2142)for permanent damage.The injury incidence in the nerves exposure and non-exposure groups was 0.30% and 0.80%,respectively,the difference was significant between the two groups(P0.05).Conclusions The occurrence of recurrent laryngel nerve injury can be reduced or avoided by its careful exposure and identification during thyroid operation.
