Isolated oedema of the uvula induced by intense snoring and ACE inhibitor.

A case of snoring-induced angioedema of uvula is described in a patient who was treated with ACE inhibitor. The patient partially responded to complement C1-inhibitor concentrate and did not suffer any recurrences after the medication was withdrawn. When encountering a patient suffering from swellings of the orofacial area it should be considered whether the mechanism is mast-cell associated or not, as classical antiallergic treatment is ineffective in non-mast-cell-associated disease (ie, bradykinin-mediated angioedema). Other causes of uvular oedema are also discussed.
