Q

What causes peritonsillar abscesses?

A

Peritonsillar abscesses are usually a complication of untreated or partially treated tonsillitis, although it can arise without tonsillitis.

Quinsy can occur just as frequently in teenagers and young adults as it does in children, unlike tonsillitis which is much more common in children.

Q

Management of quinsy?

A

Patients should be referred into hospital under the care of the ENT team for incision and drainage of the abscess under general anaesthetic.

Quinsy typically has an underlying bacterial cause, therefore antibiotics are appropriate before and after surgery. A broad spectrum antibiotic such as co-amoxiclav would be an appropriate choice to cover the common causes, but local guidelines will guide antibiotic choice according to local bacterial resistance.

Some ENT surgeons give steroids (i.e. dexamethasone) to settle inflammation and help recovery, although this is not universal.
