Summary
Retrosternal goiters are often symptomatic and can be surgically managed via cervical incision with low malignancy rates. Thyroidectomy is recommended for these thyroid enlargements.
Area of Science:
- Endocrinology
- Surgical Oncology
- Thoracic Surgery
Background:
- Retrosternal goiter is defined as thyroid enlargement extending below the thoracic inlet.
- Management guidelines are needed due to potential complications like tracheomalacia, nerve palsy, and hypocalcemia.
Purpose of the Study:
- To characterize patients and retrosternal goiters.
- To evaluate surgical techniques, morbidity, and malignancy incidence.
- To establish management guidelines for retrosternal goiter.
Main Methods:
- Prospective data collection over 14 years for thyroidectomies.
- Standardized capsular dissection technique used.
- 199 cases of retrosternal extension analyzed.
Main Results:
- Retrosternal extension more common on the left (3:2 ratio).
- 83.4% of patients experienced symptom relief post-surgery.
- Low malignancy rate (2.5%) and acceptable morbidity (30% temporary hypocalcemia).
Conclusions:
- Retrosternal goiter is frequently symptomatic with a low malignancy risk.
- Surgery via cervical incision is feasible with acceptable morbidity.
- Thyroidectomy is the recommended treatment of choice.
