Brief summary: The extent of thyroid resection in benign goiter is controversial. Potential advantages of TT over BST may include: one-stage removal of incidental thyroid cancer reported in up to 10% of operatively treated benign thyroid diseases, and lower risk for goiter recurrence. However, these potential advantages should outweigh the risk of morbidity associated with more radical thyroid resection.

The aim of this study was to compare outcomes of bilateral subtotal (BST) vs. total thyroidectomy (TT) for benign bilateral thyroid disease.

Detailed description: The extent of thyroid resection in bilateral multinodular non-toxic goiter remains controversial. Surgeons still continue to debate whether the potential benefits of total thyroidectomy outweigh the potential complications. Most low-volume surgeons avoid to perform total thyroidectomy owing to the possible complications such as permanent recurrent laryngeal nerve palsy and permanent hypoparathyroidism. On the other hand, the increasing number of total thyroidectomies are currently performed in high-volume endocrine surgery units, and the indication for this procedure include thyroid cancer, Graves disease and multinodular goiter. Recently there has been increasing acceptance for performing total thyroidectomy for bilateral multinodular non-toxic goiter as it removes the disease process completely, lowers local recurrence rate and avoids the substantial risk of reoperative surgery, and involves only a minimal risk of morbidity. This common perception is based largely on single-institution retrospective data, a few multi-institutional retrospective experiences, and only a few small prospective studies comparing the outcomes of total vs. subtotal thyroidectomy.

Eligibility criteria: Inclusion Criteria:

* a benign bilateral thyroid disease with the posterior aspects of both thyroid lobes appearing normal on ultrasound of the neck.

Exclusion Criteria:

* thyroid disease involving the posterior aspect/s of thyroid lobe/s,
* suspicion of thyroid cancer,
* previous thyroid surgery,
* pregnancy or lactation,
* age \< 18 years or \> 65 years,
* ASA 4 grade (American Society of Anesthesiology),
* and inability to comply with the follow-up protocol.

Primary outcomes:
measure: Primary outcome measure was the prevalence of recurrent goiter, incidental thyroid cancer and need for revision thyroid surgery.
timeFrame: folow-up at yearly intervals following thyroidectomy
Secondary outcomes:
measure: Secondary outcome measure was the postoperative morbidity rate (hypoparathyroidism, recurrent laryngeal nerve injury and bleeding).
timeFrame: 12-month follow-up after thyroidectomy
Other outcomes:
