Quick FAQ: When should I see an ENT specialist?
Breathing/swallowing difficulty, rapid enlargement or a new persistent adult neck lump needs prompt specialist assessment.
How I assess this in clinic
I first clarify duration, severity, whether symptoms are one-sided or bilateral, and their effect on daily life. I then perform a focused ENT examination and compare the findings with usually a lateral neck lump.
Endoscopy or audiometry is not required for everyone. I advise endoscopy when the nose, sinus, throat or voice box needs direct assessment, and audiometry/tympanometry when hearing or middle-ear function is in question.
A common misconception is that every ENT problem needs an antibiotic or an operation. Treatment should instead follow the diagnosis, functional impact, examination findings and evidence-based indications.
Do not wait when: Breathing/swallowing difficulty, rapid enlargement or a new persistent adult neck lump needs prompt specialist assessment.
