Abstract: Objective   To explore the clinical significant on protection of parathyroid and recurrent laryngeal nerve（RLN）by meticulous capsular dissection in thyroid lobectomy.Methods  Clinical date of 211 patients who underwent thyroid lobectomy by meticulous capsular dissection were retrospectively analyzed.  Results  All of the 211cases underwent thyroid lobectomy successfully without death,and the operative time was 85 min.The pathological results showed that there were thyroid papillary carcinoma in 48 cases,thyroid medullary carcinoma in one case,thyroid adenoma in 21 cases and nodular goiter in 141cases.After operation,12 cases suffered transient hypocalcemia whose symptom disappeared witnin one week to one month after therapy;3 cases suffered hoarseness whose symptom disappeared after one month,there was no case suffering permanent hypocalcemia and laryngeal nerve injury.There was no recurrence happened during the followed up period.No recurrence was found during the followup period. Conclusion  Meticulous capsular dissection can effectively protect function of parathyroid and reduce or stop the injury of RLN，so meticulous capsular dissection is worth using in the clinical practice.
