Plain English Summary

Background and study aims
Secretory otitis, commonly referred to as glue ear, is a childhood condition where fluid (mucus) builds up in the middle ear. This can cause hearing problems and affect the child’s social adaptation and academic performance. The mucus can just stay in the ear, can cause a hole to develop in the eardrum (perforated eardrum), or can cause an ear infection (acute otitis media), which would require treatment with antibiotics. The recent guidelines concluded that there is no single effective treatment for secretory otitis, and recommend a period of three months of monitoring during which the secretory otitis may improve spontaneously. If there is no improvement after 3 months, surgical treatment may be required to place tubes (grommets) in the ear to drain the mucus, with or without adenoidectomy (an operation to remove the adenoids). The aim of this study is to assess the effectiveness of homeopathy as an addition to the conventional treatment for children with secretory otitis.

Who can participate?
Children age 2 months to 12 years with secretory otitis

What does the study involve?
Participants are randomly allocated into two groups. One group receives homeopathic treatment and the other group receive a placebo (dummy drug). Both groups also receive conventional treatment (budesonide and ambroxol hydrochloride in an aerosol [spray]) for 20 days at a rate of one session per day.

What are the possible benefits and risks of participating?

Study information

Scientific title

Effectiveness of homeopathic treatment (Agraphis nutans 5CH, Thuya occidentalis 5CH, Kalium muriaticum 9CH and Arsenicum iodatum 9CH), as an adjuvant in secretory otitis (SO) in childhood: a randomized parallel double-blind clinical trial


Study hypothesis

The coadjuvancy with homeopathy, in patients aged 2 months to 12 years, can improve or resolve the SO, diagnosed through the Bilateral pneumatic otoscopy (OPN), the primary endpoint being a dichotomous one (positive or negative mobility of the tympanic membrane).

Primary outcome measures

The presence or absence of secretory otitis in childhood depending on the tympanic mobility measured with pneumatic otoscopy

Secondary outcome measures

1. Need for surgery (DTT + / - adenoidectomy) in any of the patient's ears with secretory otitis at the end of study to meet the surgical indications of the Spanish Society of Otolaryngology and cervico-facial
2. Number of Secretory Otitis Media, Secretory Otitis Media complicated and tympanic perforations in one of the two ears of patients with secretory otitis during the study period (3 months)
3. Number of days of absence from school or work, the patient or primary caregivers have been forced to make during the study period (3 months) for reasons related to hearing problems (Secretory Otitis Media, Complications of Secretory Otitis Media or perforated eardrum)
4. The proportion and type of intercurrent adverse events will be collected during the trial in both study groups
