Persistent Symptoms After Tympanostomy Tube Placement

Immediate Diagnostic Evaluation

The American Academy of Otolaryngology-Head and Neck Surgery recommends performing pneumatic otoscopy to verify the tube is patent, properly positioned, and that the tympanic membrane is not retracted, for patients with persistent symptoms after tympanostomy tube placement 1
Obtain tympanometry to assess for persistent type B (flat) pattern, which would indicate continued middle ear dysfunction despite the tube, in patients with ongoing symptoms after tube placement 1
Conduct age-appropriate hearing testing to quantify any conductive hearing loss, which should improve by 6-12 dB with patent tubes, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 2, 1

Tube obstruction or malfunction can prevent adequate middle ear ventilation, leading to persistent symptoms, according to the American Academy of Otolaryngology-Head and Neck Surgery 1
Persistent middle ear effusion may not drain adequately even with a patent tube, causing ongoing symptoms, as noted by the American Academy of Otolaryngology-Head and Neck Surgery 1
Underlying sensorineural hearing loss would not improve with tubes and requires separate evaluation, as stated by the American Academy of Otolaryngology-Head and Neck Surgery 3

The American Academy of Otolaryngology-Head and Neck Surgery recommends continuing observation for 3 months total from the time of tube placement, for patients with patent and functioning tubes 1
Optimize the listening environment if mild hearing loss persists, by getting within 3 feet before speaking, turning off background noise, and facing the child when speaking, as suggested by the American Academy of Otolaryngology-Head and Neck Surgery 4
Consider nasal balloon auto-inflation as an adjunct therapy, which has demonstrated benefit (NNT=9) for clearing middle ear effusion, according to the American Academy of Otolaryngology-Head and Neck Surgery 2, 1

Do not assume tubes are functioning without direct visualization, always examine the tympanic membrane to confirm tube patency, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 1
Do not use intranasal corticosteroids for Eustachian tube dysfunction, as they have shown no improvement in symptoms or middle ear function, according to the American Academy of Otolaryngology-Head and Neck Surgery 2, 1
Do not use topical nasal decongestants for more than 3 days to prevent rhinitis medicamentosa, as stated by the American Academy of Otolaryngology-Head and Neck Surgery 2

Patients should experience immediate relief of pressure sensation as the tube allows direct air entry into the middle ear, according to the American Academy of Otolaryngology-Head and Neck Surgery 1
Hearing improvement of 6-12 dB is expected while tubes remain patent, as noted by the American Academy of Otolaryngology-Head and Neck Surgery 2, 1
Resolution of muffled hearing should occur within days to weeks, as stated by the American Academy of Otolaryngology-Head and Neck Surgery 1
