Ear Tube Placement for Recurrent Ear Infections and Persistent Middle Ear Fluid

Purpose of Ear Tubes

• The American Academy of Otolaryngology-Head and Neck Surgery recommends tympanostomy tube insertion as the most effective treatment for persistent middle ear fluid causing hearing loss and for recurrent ear infections with persistent fluid, providing immediate ventilation of the middle ear and reducing future infection episodes 1, 2
• Ear tubes are small tubes approximately 1/20th of an inch in width that are placed in the eardrum to ventilate the middle ear space, providing a direct pathway for air to enter the middle ear, bypassing the poorly functioning eustachian tube in children 1, 3
• Tubes eliminate negative pressure (vacuum) in the middle ear that can cause fluid buildup and infections, and allow drainage of fluid from the middle ear space, preventing buildup that can cause hearing loss 4, 2
• The procedure is typically performed under general anesthesia but can sometimes be done in-office, and the entire procedure is brief, usually taking less than 15 minutes 3, 4

Primary Indications for Placement

• The American Academy of Otolaryngology-Head and Neck Surgery indicates that ear tubes are recommended for chronic OME (fluid persisting for 3 months or longer) with hearing difficulties, and when fluid is present in both ears and causing hearing loss 5
• Tubes are an option when chronic fluid contributes to balance problems, poor school performance, behavioral problems, ear discomfort, or reduced quality of life 5
• The American Academy of Otolaryngology-Head and Neck Surgery recommends tubes for recurrent AOM (3+ episodes in 6 months or 4+ episodes in 12 months with at least 1 in the past 6 months) WITH persistent middle ear fluid 5, 3

Special Populations

• Children with risk factors for developmental difficulties, such as permanent hearing loss, speech/language delay, autism spectrum disorder, Down syndrome, cleft palate, blindness, developmental delay, intellectual disability, learning disorders, or ADHD, may benefit from earlier tube placement 3

Procedure for Ear Tube Placement

• A surgical incision (myringotomy) is made in the tympanic membrane, and a small tube is inserted through the incision to maintain an opening in the eardrum 1

Types of Ear Tubes

• Short-term tubes last approximately 8-18 months before naturally extruding, while long-term tubes last 2+ years but have a higher risk of complications 5
• The American Academy of Otolaryngology-Head and Neck Surgery recommends short-term tubes for initial surgery unless there is a specific need for prolonged ventilation 6, 7

Benefits of Ear Tube Placement

• Reduction in future ear infection episodes, and improved quality of life, including better sleep, daytime behavior, and social interactions 4
• Allows treatment of ear infections with antibiotic ear drops rather than oral antibiotics, and may improve developmental progress in children receiving therapy for delays 4

Potential Complications

• Persistent tympanic membrane perforation after tube extrusion (risk higher with long-term tubes), and tympanostomy tube otorrhea (drainage through the tube) 5, 8
• Risks associated with general anesthesia 4

Important Clinical Considerations

• Most ear problems resolve by age 7-8 years as the eustachian tube matures and the immune system develops, and for children ≥4 years old, adenoidectomy may be considered along with tube placement to reduce future recurrence and need for repeat tubes 4, 6, 9

Follow-up Care

• Regular monitoring every 3-6 months is recommended for children who have ear tubes, and if a child has ear tubes and develops an ear infection, drainage will often be visible from the ear canal 5, 10
• Infections with tubes in place can typically be treated with antibiotic ear drops rather than oral antibiotics 4

Pressure Equalization Tube Placement for Recurrent Acute Otitis Media

Definition and Indications

• The American Academy of Otolaryngology-Head and Neck Surgery recommends that PE tubes should be offered to children with recurrent acute otitis media (AOM) defined as 3 or more well-documented episodes in 6 months OR 4 or more episodes in 12 months with at least 1 episode in the preceding 6 months, AND who have middle ear effusion (MEE) present at the time of assessment 11, 12
• Recurrent AOM is defined as 3 or more well-documented and separate AOM episodes in a 6-month period OR 4 or more episodes in a 12-month period with at least 1 episode in the preceding 6 months, according to the American Academy of Pediatrics 13
• Risk factors for recurrence include winter season, male gender, and passive smoke exposure, as noted by the American Academy of Pediatrics 13

Indications for PE Tube Placement

• The American Academy of Otolaryngology-Head and Neck Surgery indicates that clinicians should NOT place PE tubes in children with recurrent AOM who do not have MEE in either ear at the time of assessment 14, 15, 12
• At-risk children with developmental concerns may benefit from earlier tube placement with less stringent criteria, as suggested by the American Academy of Otolaryngology-Head and Neck Surgery 14, 16

Benefits of PE Tubes for Recurrent AOM

• The American Academy of Pediatrics notes that PE tubes can reduce future AOM episodes by approximately 1.5 episodes in the 6 months following surgery 13

Pre-Procedural Evaluation

• The American Academy of Otolaryngology-Head and Neck Surgery recommends that hearing evaluation should be obtained prior to surgery when a child becomes a candidate for PE tube insertion 14, 12
• Clinicians should determine if a child is at increased risk for speech, language, or learning problems from otitis media due to baseline sensory, physical, cognitive, or behavioral factors, as advised by the American Academy of Otolaryngology-Head and Neck Surgery 15

Alternative Management Options

• For children with recurrent AOM without MEE at the time of assessment, observation with episodic treatment is recommended by the American Academy of Otolaryngology-Head and Neck Surgery 14, 15, 12

Follow-up Care

• Clinicians should educate caregivers about the expected duration of tube function and detection of complications, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 15

Spontaneous Tympanostomy Tube Extrusion: Evidence‑Based Guidelines

Definition and Natural Course

• Spontaneous tube extrusion is the expected, normal endpoint of tympanostomy tube function and is not considered a complication; it reflects the tube being expelled as the tympanic membrane heals and migrates laterally. American Academy of Otolaryngology‑Head and Neck Surgery (AAO‑HNS) notes this definition. 17, 18

• Normal spontaneous extrusion is identified when the tube is visualized in the external auditory canal or has fallen out completely, and the tympanic membrane heals closed without a residual perforation. 17, 18

Timing and Premature Extrusion

• Premature extrusion—tube loss before adequate middle‑ear ventilation—is observed in approximately 7.7 % of cases and occurs more frequently in children with recurrent acute otitis media than in those with chronic otitis media with effusion. 17

Complications Related to Tube Position

• Tube medialization (displacement of the tube into the middle‑ear space) constitutes a true complication that requires surgical removal, according to AAO‑HNS guidance. 17, 18

• A retained tube—defined as a tube persisting beyond its expected lifespan (greater than 2 years for short‑term tubes)—increases the risk of adverse events and should be considered a complication. 18

Clinical Management

• Caregivers should receive education during the peri‑operative period about the anticipated duration of tube function and that spontaneous extrusion is normal, as recommended by AAO‑HNS. 18, 19, 20

• After tube extrusion, a follow‑up otoscopic examination is required to confirm that the tympanic membrane has healed properly and that no persistent perforation remains. 17, 18

• Routine periodic follow‑up should continue until tube extrusion occurs, with an initial examination scheduled within 3 months of tube insertion and ongoing monitoring thereafter. 19, 20
