How to Use the Otovent Device for a 7-Year-Old Child
The Otovent device is used by having the child blow into a nosepiece to inflate a balloon through one nostril while pinching the other nostril closed, performing this 3 times per nostril, twice daily for 1-3 months 1.
Step-by-Step Instructions
Preparation
- Attach the balloon to the nosepiece of the Otovent device
- Have the child sit comfortably in an upright position
Technique
- Insert the nosepiece into one nostril while pinching the other nostril closed with fingers
- Blow steadily through the nose to inflate the balloon to approximately the size of a grapefruit
- Repeat this inflation 3 times through the same nostril
- Switch sides and perform 3 inflations through the other nostril
- Frequency: Perform this routine twice daily (morning and evening works best for most families)
Duration of Treatment
Continue treatment for 1-3 months as recommended in the primary care evidence 1. The highest success rates occur when treatment is maintained for the full duration, with compliance rates of 89% at 1 month and 80% at 3 months 1.
Making It Work for Children
The key to success is making the treatment enjoyable and incorporating it into the daily routine 2. Consider these strategies:
- Gamification: Turn it into a game or competition (who can blow the biggest balloon)
- Routine integration: Link it to existing daily activities like brushing teeth
- Initial excitement: Children are often excited by the novelty initially, but maintaining engagement requires creativity 2
- Parental involvement: Most children can successfully use the device with parental assistance, even when they cannot perform a Valsalva maneuver 3, 4
Clinical Effectiveness
The evidence shows that autoinflation is effective for otitis media with effusion (OME) in school-aged children, with 47.3% achieving normal tympanograms at 1 month and 49.6% at 3 months, compared to 35.6% and 38.3% in controls respectively 1. This represents a number needed to treat of 9 children 5, 1. The device also produces significant improvements in ear-related quality of life and hearing outcomes 1.
Important Caveats
Contraindications - Do NOT use if the child has:
- Skull base or orbital defects
- Craniofacial anomalies
- Active ear infection or inflammation 6
Expected Side Effects
- Mild ear pain during the first week is common in approximately half of children but is generally tolerable 6
- Adverse events are otherwise mild, infrequent, and comparable to no treatment 1
When Treatment May Fail
Be aware that autoinflation is less effective in children with:
- Recurrent OME
- Recurrent or prolonged respiratory tract infections
- History of previous middle ear surgery 6
Where to Purchase
The Otovent device can be purchased from:
- Pharmacies: Available over-the-counter at most major pharmacy chains
- Online retailers: Amazon, medical supply websites
- Medical equipment suppliers
- Direct from manufacturer: Otovent is manufactured by Abigo Medical (Sweden)
The device typically costs between $15-30 USD and includes the nosepiece and multiple balloons for replacement.
Clinical Context
Autoinflation with Otovent represents a reasonable first-line conservative treatment option before considering surgical intervention (ventilation tubes) for persistent OME 5. Current guidelines recommend a 3-month period of watchful waiting before surgical intervention 5, and autoinflation fits well within this timeframe as a non-invasive alternative. The device generates lower but significantly more consistent pressures than the Valsalva maneuver (278 daPa vs 486 daPa plateau pressure), making it more suitable for diagnostic and therapeutic purposes in children 7.
