Isthmusectomy
Surgical removal of only the central isthmus of the thyroid — used for select small, well-defined nodules limited to this area, sparing both lobes and preserving full thyroid function.
What is Isthmusectomy?
Isthmusectomy is the surgical removal of only the central isthmus of the thyroid gland — the narrow bridge of tissue connecting the two lobes. It is selected for small, well-defined nodules confined entirely to the isthmus, especially low-risk cancers or worrisome benign lesions. By sparing both lobes, isthmusectomy preserves full thyroid function and avoids the need for lifelong hormone replacement in most patients. Dr. Tejasree Vengala performs isthmusectomy at Lux Hospitals, Hyderabad, with a small, well-concealed neck crease incision and excellent cosmetic results.
How the Procedure Works
Anaesthesia & Preparation
Surgery is performed under general anaesthesia. The neck is positioned in slight extension and the area is prepared and draped.
Small Neck Crease Incision
A small 3–4 cm incision is placed in a natural neck crease for the best cosmetic outcome.
Isthmus Mobilisation
The strap muscles are gently separated to expose the isthmus, which is dissected off the trachea with care.
Targeted Removal
The entire isthmus, including the nodule with a healthy margin, is removed without disturbing either lobe.
Closure & Recovery
The wound is closed in layers with absorbable sutures and skin glue. Most patients are discharged the same day or next, with quick recovery.
Outcomes
Who Needs This Treatment?
- →Both thyroid lobes are completely preserved
- →Most patients avoid lifelong hormone medication
- →Targeted removal of isthmus nodules with clear margins
- →Smaller incision and quicker recovery than full thyroidectomy
- →Excellent cosmetic outcome with neck crease scar
- →Suitable for select low-risk cancers limited to the isthmus
Isthmusectomy is a great example of doing exactly what the patient needs — no more, no less. When a nodule is sitting cleanly in the isthmus, removing only that segment spares both lobes and almost always spares the patient lifelong tablets.
