[Evidence-based treatment options for allergic diseases in otolaryngology: an update].

Allergic diseases in the area of otolaryngology (ENT) are common, increasing and associated with a number of comorbid disorders, such as bronchial asthma and atopic dermatitis. If allergen avoidance is not possible, allergen-specific immunotherapy is the only causative treatment option. Options for pharmacotherapy are mast cell stabilizers, antihistamines, glucocorticoids, leukotriene receptor antagonists and nasal decongestants. In type 1 allergic reactions, topical glucocorticoids are currently the most effective treatment and are considered to be the first-line therapy together with nonsedating antihistamines. A novel formulation (MP29-02) combining a nasal glucocorticoid and antihistamine in one single preparation has demonstrated an improvement of the effective total nasal symptom score by 39 % in comparison to monotherapy with fluticasone propionate. In type IV allergies, such as eczema treatment with topical glucocorticoids or calcineurin inhibitors is standard.
