Write a five mark short note on complication of thyroidectomy Make it compatible, compact but high yielding. So that... I can easily remember and, uh, write it in a... Systematic way being a 2nd year resident.

I now have excellent material from multiple authoritative surgical textbooks. Let me compile the comprehensive, high-yield, exam-ready short note:

Complications of Thyroidectomy

(5-mark short note — Systematic, High-Yield, Resident-Ready)

Classification

Complications are best remembered under "SHIT" mnemonic or organized by timing + system:

I. Immediate (Intraoperative / Within 24 hrs)

1. Haemorrhage / Neck Haematoma

Incidence: ~1%
Most dangerous complication - can cause airway compromise by venous congestion and tracheal compression
Mx: Immediately open the wound at bedside (do NOT wait for OT) to relieve airway compression, then take to OT for formal exploration
Fischer's Mastery of Surgery

2. Airway Injury / Tracheomalacia

Seen with long-standing large goiters - tracheal rings weakened by chronic pressure
Can collapse after gland removal
Risk of pneumothorax during substernal goitre resection
Barash Clinical Anesthesia, 9e

II. Early (24 hrs - 1 week)

3. Hypocalcemia / Hypoparathyroidism ⭐ (Most Common)

Due to: inadvertent removal, devascularization, or manipulation of parathyroid glands
Symptoms appear 24-96 hrs post-op
Features: perioral tingling, carpopedal spasm, tetany, laryngospasm (can be first sign), Chvostek's sign, Trousseau's sign
Transient: 1-30% (most recover within 1 month)
Permanent: ~2% (high-volume centres)
Highest risk: total thyroidectomy + central neck dissection
Hungry Bone Syndrome: severe/prolonged hypocalcaemia in hyperthyroid patients post-op (despite normal PTH) - also low Mg, low PO₄, high K
Mx: IV calcium gluconate (acute); oral calcium + Vit D (maintenance)
Current Surgical Therapy 14e; Fischer's Mastery; Barash

4. Recurrent Laryngeal Nerve (RLN) Injury ⭐ (Most Significant)

Transient hoarseness: up to 80% (resolves in weeks-months)
True RLN palsy: up to 10%; up to 30% in re-operative setting
Permanent: ~1-2% with experienced surgeons
Unilateral: hoarseness, weak voice, bovine cough
Bilateral: stridor, dyspnoea, aphonia - requires immediate reintubation / tracheostomy
Palsy lasting >6 months = likely permanent (may take up to 2 years to resolve)
Prevention: direct visualisation + Intraoperative Nerve Monitoring (IONM)
Fischer's Mastery; Current Surgical Therapy 14e; Barash

5. Superior Laryngeal Nerve (External Branch - EBSLN) Injury

Results in loss of cricothyroid muscle function
Features: inability to hit high notes, change in voice pitch, loss of voice projection
Often subtle; significant for singers and voice professionals
Sabiston Textbook of Surgery

III. Late Complications

6. Hypothyroidism

Inevitable after total thyroidectomy - requires lifelong levothyroxine
Can occur in up to 30-50% after subtotal thyroidectomy
Fischer's Mastery; Washington Manual

7. Thyroid Storm (Thyrotoxic Crisis)

Rare (~1-5% of hospitalised thyrotoxic patients), mortality up to 25%
Triggered by: surgery in a non-euthyroid patient, cessation of ATD, acute stress
Burch-Wartofsky scoring system for diagnosis
Prevention: ensure biochemically euthyroid before surgery (ATDs ± beta-blockers ± Lugol's iodine for Graves')
Current Surgical Therapy 14e

8. Wound Complications

Infection, keloid scar, poor cosmesis
Rare with transverse cervical incision placed in skin crease

Quick Recall Table

Complication	Key Feature	Timing
Haematoma	Open wound at bedside	Immediate
Hypocalcemia	Tetany, 24-96 hrs	Early
RLN - Unilateral	Hoarseness	Early/Late
RLN - Bilateral	Stridor + emergency airway	Immediate
EBSLN	Loss of high pitch	Late
Hypothyroidism	After total thyroidectomy	Late
Thyroid Storm	Non-euthyroid at surgery	Perioperative

Exam Tip Mnemonic: "H-H-R-S-T-W"

Haematoma - Hypocalcemia - RLN injury - SLN (external) - Thyroid storm - Wound/hypothyroidism

Complications of Thyroidectomy - High Yield Flashcard

Here's your pre-exam revision flashcard! Here's how to use it:

3 columns by timing - your eye naturally moves left to right as complications unfold: Immediate → Early → Late/Special

What to drill:

Red flags: Haematoma = open neck at bedside (not in OT). Bilateral RLN = emergency airway. These are the classic exam traps.
The two ⭐ stars = most common (Hypocalcaemia) and most significant (RLN injury) - examiners love these
Hungry Bone Syndrome is a high-yield differentiator from simple hypoparathyroidism
Thyroid Storm mortality (25%) and the Burch-Wartofsky score name are easy marks

The mnemonic H²-R-S-T-W at the bottom anchors all 6 categories so you don't blank in the exam hall. Run through it once before you write - takes 10 seconds.
