Compressive symptoms: nodule size and orthopnoea, not globus, pick the patients who improve

Design

Single-centre retrospective cohort study over ten years

Population

214 patients (87% women, average age 50) referred for compressive symptoms attributed to thyroid nodules, goitre or cysts, 2015-2025

Primary outcome

Symptom resolution correlated with imaging findings, treatment and alternative diagnoses

Effect

82 (38%) operated, 83% improved; median nodule volume 36.41 vs 6.38 cm³ (p<0.05); dyspnoea and orthopnoea predicted surgery (both p<0.01); orthopnoea resolution 91%

"Compressive symptoms" is a phrase that carries an assumption — that the gland is doing the compressing. This review of every patient referred to one academic otolaryngology clinic between 2015 and 2025 with aerodigestive symptoms attributed to thyroid nodules, goitre or cysts tests that assumption against outcomes. Two hundred and fourteen patients, 87% women, average age 50.

Eighty-two (38%) had thyroid surgery and 69 of them (83%) reported improvement. The other 110 were not recommended for surgery, and their commonest presenting symptoms were globus (n=18) and dysphagia (n=21). The commonest alternative diagnoses in that group were gastro-oesophageal reflux disease (n=39, 36%) and laryngeal muscle tension (n=39, 23%).

What separated the two groups was size and symptom type. Median nodule volume was 36.41 cm³ in those operated on against 6.38 cm³ in those not (p<0.05). Dyspnoea (n=35, p<0.01) and orthopnoea (n=29, p<0.01) both predicted a surgical recommendation — and patients with orthopnoea had the highest resolution rate after surgery, at 91%.

The change this argues for is in the workup, not the operation. A patient sent with globus and a 6 cm³ nodule needs a reflux and muscle-tension assessment before a surgical discussion, because the operation is unlikely to fix what is wrong. A patient who cannot lie flat with a 36 cm³ goitre is a different patient. In India, where goitre prevalence and the volume of thyroid referrals are both high, sorting those two apart at the first visit is worth real clinic time.

• Measure nodule volume, not maximum diameter, when assessing compression
• Treat globus plus a small nodule as a reflux or muscle-tension problem until shown otherwise
• Orthopnoea is the symptom with the best postoperative resolution rate — 91% here
• Offer the alternative diagnosis explicitly rather than simply declining surgery
• Document why surgery was not recommended, because the patient will be re-referred

Why it matters

It gives concrete selection criteria for an operation currently offered on the strength of a phrase in a referral letter.

Don't overread it

Improvement was patient-reported in a selected surgical group with no comparator; this is not evidence of a treatment effect.

The statistics, in plain English

This is a retrospective review, so patients were selected for surgery by clinicians who expected them to improve — the 83% improvement rate reflects that selection as much as the operation. The size difference is large enough to be meaningful (roughly sixfold in median volume), but 'improvement' was self-reported without a validated instrument, and no one compared operated patients with similar unoperated ones.
