What is Thyroid Cancer Neck Dissection?

Cervical lymph node metastasis in differentiated thyroid cancer (DTC) is common - 50-80% in papillary, 20-30% in follicular. Central compartment (level VI) is the first-station drainage; metastases progress to lateral compartments (II-V) thereafter. Therapeutic neck dissection is mandatory for clinically apparent or biopsy-proven nodal disease (cN1). Prophylactic central neck dissection (PCND) for cN0 is debated and performed selectively (T3-T4, multifocality, age >55).

Central neck dissection (CND) - level VI: includes prelaryngeal (Delphian), pretracheal, paratracheal (right and left), and tracheoesophageal lymph nodes. Boundaries: superior - hyoid, inferior - innominate vessels, lateral - carotid sheath. Critical structures: recurrent laryngeal nerve (always identified-preserved), superior and inferior parathyroids, esophagus, trachea. Postoperative complications: hypoparathyroidism (20-30%), recurrent nerve paralysis (1-3%).

Lateral neck dissection (LND): levels II-V (modified radical neck dissection - MRND), preserves accessory nerve (level V), internal jugular vein, sternocleidomastoid muscle. Critical structures: vagus nerve, thoracic duct (left side), accessory nerve, internal jugular vein, common carotid artery. Indications: biopsy-proven lateral metastasis (FNAC + thyroglobulin washout), suspicious USG criteria. Outcomes: dissection extent and recurrence rate inversely correlated.

Symptoms

Cervical mass and palpable lymph node
USG-detected lateral cervical lymphadenopathy
Hoarseness (recurrent nerve invasion)
Dysphagia (advanced disease)
Persistent thyroglobulin elevation
Asymptomatic - imaging finding

Risk Factors

Differentiated thyroid cancer (papillary)
Tumor size >2 cm
Multifocality
Extrathyroidal extension
Age >55 years
Family history (familial DTC)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Cervical lymph node mass detected
  • Suspicious USG (round, hilum loss, microcalcification)
  • FNAC + thyroglobulin washout positive
  • Surgical planning before primary thyroidectomy
  • Recurrence-progression in known DTC
  • Multidisciplinary council evaluation

Treatment Methods

01
Therapeutic CND/LND (proven metastasis)
02
Recurrent laryngeal nerve identification (always)
03
Parathyroid preservation (autotransplantation)
04
Postoperative thyroglobulin and Tg-Ab follow-up
05
RAI ablation (post-RAI scan)
06
Long-term USG and biochemical surveillance
