Risks are minimal — bleeding, wound infection, and very rare nerve or parathyroid issues because dissection is strictly central. It is one of the lower-risk thyroid operations when performed for the right indication.

✦ Isthmusectomy

Isthmusectomy

Q: Who is suitable for isthmusectomy?

Patients with an isolated nodule confined to the isthmus — either benign, indeterminate, or a small low-risk papillary microcarcinoma. Pre-op ultrasound must confirm no extension into either lobe or nearby structures.

Q: Will I need thyroid medication?

Usually not — both lobes remain intact and functional, so thyroid hormone levels typically stay normal. Periodic blood tests are recommended to confirm ongoing normal function during follow-up.

Q: Is surveillance needed afterward?

Yes — annual ultrasound and thyroid function tests ensure the remaining thyroid stays healthy and monitors for any new nodules. For cancer cases, closer surveillance with TSH monitoring is recommended long-term.

Removal of only the central thyroid isthmus — a selective operation for isolated isthmic nodules or small cancers limited to the isthmus.

What is Isthmusectomy?

Isthmusectomy is the surgical removal of only the thyroid isthmus — the narrow central portion that connects the two thyroid lobes. It is a selective procedure indicated for isolated benign or small low-risk malignant nodules confined strictly to the isthmus, avoiding the need for lobectomy or total thyroidectomy. Dr. Abhishek performs isthmusectomy at Lux Hospitals through a small collar incision, preserving both thyroid lobes and their vascular supply, with minimal risk to the recurrent laryngeal nerves and parathyroid glands.

How the Procedure Works

Anaesthesia & Positioning

General anaesthesia is given; the patient is positioned supine with the neck extended.

Small Collar Incision

A 3–4 cm transverse incision is made in a natural skin crease for access to the central thyroid.

Isthmus Exposure

Strap muscles are separated in the midline; the isthmus is exposed with clear margins on each side.

Vessel Control & Division

Small isthmic vessels are ligated; the isthmus is divided from each lobe with clear tissue margins.

Closure

Haemostasis is confirmed; strap muscles are approximated; skin is closed with subcuticular sutures.

Who Needs This Treatment?

→Preserves both thyroid lobes and maximum gland function
→Very low risk of hypothyroidism or hypocalcaemia
→Minimal risk to the recurrent laryngeal nerves
→Short procedure with same-day or next-day discharge
→Small cosmetic scar in a natural neck crease
→Ideal for isolated isthmic nodules without extension

For a patient with an isolated isthmic nodule, isthmusectomy is an elegant, gland-sparing solution. It treats the problem definitively while preserving normal thyroid function — a genuinely patient-centred operation.
