What is the treatment for blocked Eustachian tubes for adults

The short version: for most adults with blocked Eustachian tubes, the first-line treatment is a stepwise self-inflation technique, not drugs or surgery.

The evidence for a stepwise approach is solid. A 2021 study tested a sequence of Valsalva, extended Valsalva, and then a nasal balloon (Otovent) in 134 ears with negative pressure after a flight [1]. The combined method restored normal middle ear pressure in 86% of ears [1]. The nasal balloon alone worked for 69% of ears that failed the simpler maneuvers [1]. This is a cheap, low-risk, self-administered treatment that you can try at home.

Drugs are a different story. A 2017 trial on otitis media with effusion (fluid behind the eardrum, a common cause of blockage) in children found that oral steroids speeded up short-term resolution but offered no benefit at all by 6 months compared to watchful waiting [2]. Intranasal steroid sprays were no better than doing nothing [2]. The evidence for steroids in adults is even thinner, and the long-term risks of oral steroids (immune suppression, bone density loss, blood sugar disruption) are not trivial. The burden of proof for putting a drug into your body for a blocked ear is high, and this evidence does not meet it.

For chronic, treatment-resistant cases, balloon dilation of the Eustachian tube is a surgical option. A large retrospective study of 622 patients (1076 ears) reported that 71% of ears improved at 2 months and 73% at 1 year, with a revision surgery rate of 10.5% [3]. No serious complications were reported in that study [3]. But this is a procedure that involves inflating a balloon to 10 bars of pressure inside the tube for 2 minutes [3]. The evidence comes from a retrospective cohort, not a randomized trial against sham surgery or continued conservative care. The long-term durability is unclear: at 4 years, only 2 patients had data, and their scores had dropped [3]. The burden of proof for an invasive procedure on a healthy body part is high, and the evidence here is moderate at best.

My call: start with the stepwise self-inflation sequence (Valsalva, hold, then nasal balloon) for at least a few weeks. Skip steroids and sprays unless there is clear allergic inflammation. Reserve balloon dilation for cases that fail months of conservative treatment and cause significant symptoms. Confidence: high for the self-inflation approach, moderate for the surgical option, low for drug treatments.
