Summary

Eczematous otitis externa is a common inflammatory condition of the external auditory canal characterized by itching, discomfort, discharge, and pain. Topical corticosteroids are widely used for treatment; however, alternative therapies with fewer side effects are of increasing interest. This study aims to compare the efficacy of Nigella sativa (black seed) oil and mometasone furoate ear drops in the treatment of eczematous otitis externa. Nigella sativa is a natural product with known anti-inflammatory and antimicrobial properties. In this randomized, controlled clinical trial, adult patients with eczematous otitis externa will be assigned to receive either Nigella sativa oil or mometasone furoate ear drops for 10 days. Clinical symptoms and inflammatory findings will be evaluated at baseline and after treatment. The objective of this study is to determine whether Nigella sativa oil is an effective and safe alternative to topical corticosteroid therapy.

Detailed description

Eczematous otitis externa is a chronic inflammatory condition of the external auditory canal characterized by pruritus, erythema, scaling, and discomfort. Although topical corticosteroids are commonly used as first-line therapy, their prolonged use may be associated with adverse effects, prompting interest in alternative treatment options. Nigella sativa oil, a natural product with documented anti-inflammatory, antioxidant, and antimicrobial properties, may represent a potential therapeutic alternative in inflammatory ear conditions. This study will be conducted as a prospective, randomized, single-blinded, controlled clinical trial. Adult patients with clinically diagnosed eczematous otitis externa will be randomly assigned in a 1:1 ratio to receive either Nigella sativa oil or mometasone furoate 0.1% ear drops, administered twice daily for 10 days. Clinical assessments will be performed at baseline and at the end of treatment. Patient-reported symptoms, including itching, discomfort, otorrhea, and pain, will be evaluated using a numeric rating scale. Objective inflammatory findings, including hyperemia and squamation of the external auditory canal and external ear, will be assessed using standardized photographic documentation by a blinded evaluator. The primary outcome will be the change in objective inflammatory findings from baseline to the end of treatment. Secondary outcomes will include changes in patient-reported symptom scores. The results of this study are expected to provide evidence regarding the efficacy and safety of Nigella sativa oil as a potential alternative to topical corticosteroid therapy in the management of eczematous otitis externa.

Conditions

Interventions

Type	Name	Description
DRUG	Mometasone Furoate (MF)	Mometasone furoate 0.1% solution will be administered as ear drops, with two drops applied to the affected ear twice daily for 10 days. Mometasone furoate is a topical corticosteroid used for its anti-inflammatory effects.
DIETARY_SUPPLEMENT	Nigella sativa oil	Participants will receive Nigella sativa oil administered as ear drops, with two drops applied to the affected ear twice daily for 10 days.
