| Summary for Members and Families |
This document describes clinical studies and expert recommendations, and explains whether certain treatments for ear problems, such as creating a small opening in the eardrum (called a myringotomy) or placement of small tubes through the ear drum (called a tympanostomy tube) to improve the airflow and fluid drainage, are appropriate. The following summary does not replace the medical necessity criteria or other information in this document. The summary may not contain all of the relevant criteria or information. This summary is not medical advice. Please check with your healthcare provider for any advice about your health.
Key Information.
Myringotomy and tympanostomy tube insertion are treatments used when fluid builds up behind the eardrum. This fluid buildup can be caused by infections, injury, or other problems. Myringotomy in combination with or without tympanostomy tubes are commonly used to help drain fluid buildup and air move in and out of the middle ear and keep it dry. These tubes are also called ear tubes, grommets, or PE (pressure equalization) tubes. Most often, these procedures are used in children, but adults can benefit too. In some cases, doctors may perform a myringotomy without inserting tubes, especially for very young infants, people with certain health conditions, or when the eardrum is too inflamed. The procedures are usually safe and help prevent ear infections, improve hearing, and reduce pain or pressure. Newer tools can let doctors place tubes in a clinic setting without needing general anesthesia. Like all medical procedures, these come with risks and should be used only when truly needed.
What the Studies Show
Tympanostomy tubes have been studied in many clinical trials. They can help children hear better in the short term, but the benefits may not last beyond a few months. Some studies show fewer ear infections after tube placement, but others find no big difference compared to medicine alone. One large trial showed no long-term difference in ear infection rates between kids who got tubes and those who had medical treatment.. Experts agree that tubes help when ear problems cause delays in speech or learning. However, using myringotomy alone (without a tube) is not well-studied and may not work as well. It may be used in newborns or people with serious health issues when tube placement is not possible. Tympanostomy tubes are now sometimes placed in doctors’ offices using special tools for older babies and adults, avoiding the risks of general anesthesia. This in-office option works well in people who are calm and have no ear problems that could interfere with the procedure.
When is Myringotomy or Tympanostomy Clinically Appropriate?
Myringotomy with tympanostomy tube insertion may be appropriate in these situations:
Myringotomy alone may be appropriate in these situations:
When is this not Clinically Appropriate?
Myringotomy with or without tympanostomy tubes is not considered appropriate when none of the above conditions are met. The procedures should not be used for other reasons. Unnecessary procedures can lead to risks like ear discharge, scarring, or hearing problems. Studies show that tubes do not help in cases without ear fluid or when used for very short-term problems. Better studies are needed to know if myringotomy alone improves health.

| Discussion/General Information |
Summary:
This document addresses the use of myringotomy and tympanostomy tube insertion for middle ear conditions requiring decompression or prolonged ventilation and summarizes updated evidence on clinical effectiveness, procedure approaches, and patient-selection considerations. The evidence base includes randomized trials, meta-analyses, and long-term cohort studies evaluating outcomes such as hearing improvement, recurrence of otitis media, quality of life, and adverse events. The Discussion incorporates professional guidance from the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS), including updated statements from the 2022 clinical practice guideline on tympanostomy tubes in children, as well as recommendations from the American Academy of Pediatrics (AAP) regarding recurrent acute otitis media. Additional expert consensus from AAO-HNS is cited regarding in-office tympanostomy tube placement for appropriately selected individuals. This reflects a synthesis of clinical evidence and professional society recommendations relevant to the appropriate use of these procedures.
According to the AAO-HNS, myringotomy is defined as a surgical procedure in which a small incision is made in the tympanic membrane (ear drum) for the purpose of draining fluid or providing short-term ventilation. The procedure is also used to relieve pressure caused by excessive buildup of fluid or to drain pus from the middle ear. It is most commonly done as a treatment for OME but may also be considered as a treatment for ear trauma (including pressure-related barotrauma) and eustachian tube dysfunction.
Tympanostomy is a companion procedure to myringotomy and involves the insertion of a small tube into the eardrum through a myringotomy incision in order to keep the middle ear aerated for a prolonged period of time, and to prevent the accumulation of fluid in the middle ear. The procedure to place a tube involves myringotomy and is performed under local or general anesthesia. There are many different tube designs available on the market. The most commonly used type is shaped like a grommet. When it is necessary to keep the middle ear ventilated for a very long period, a "T"-shaped tube may be used, as these "T-tubes" can stay in place for 2-4 years.
The use of myringotomy and tympanostomy tube insertion has become a widely used and accepted method of treating various middle ear conditions in children and adults.
The AAO-HNS published an updated clinical practice guideline addressing the use of tympanostomy tubes in children (Rosenfeld, 2022). The recommendations are substantially unchanged from the previous guideline with the following exceptions:
Additionally, this document provides the following recommendations related to criteria for tympanostomy tube placement:
These recommendations are based on multiple studies addressing the use of tympanostomy, which demonstrate a “preponderance of benefit over harm” (Broen, 1996; Casselbrant, 1992; Gebhart, 1981; Gonzales, 1986; Hellstrom, 2011; Iino, 1999; Lous, 2012; Mandel, 1989, 1992; Paradise, 2001, 2005; Ponduri, 2009; Rosenfeld, 2011, 2016; Rovers, 2001a, 2001b, 2005; Sheahan, 2002). Additionally, the authors acknowledged a moderate to low level of evidence supporting Statement 11. The statement reflects that the expected benefit of adjunctive adenoidectomy is only a potential benefit.
The AAP published their clinical practice guideline titled The Diagnosis and Management of Acute Otitis Media in 2013 (Lieberthal, 2013). This document includes the following Key Action Statement based on multiple studies (Casselbrant, 1992; Gebhart, 1981; Gonzales, 1986; Rosenfeld, 2000; Witsell, 2005):
Clinicians may offer tympanostomy tubes for recurrent AOM (3 episodes in 6 months or 4 episodes in 1 year, with 1 episode in the preceding 6 months). (Evidence Quality: Grade B, Rec. Strength: Option).
The use of myringotomy and tympanostomy tube insertion has become accepted as a treatment method for individuals with severe complication of acute otitis media such as meningitis, intracranial abscess, mastoiditis, or facial nerve paralysis. While there is little evidence addressing such treatment, there is wide agreement in the otolaryngology community supporting it. In such cases it is deemed prudent to use myringotomy and tympanostomy to prevent further progression of complications.
In 2017, Steele published the results of a meta-analysis investigating the effectiveness of tympanostomy tubes in children with chronic otitis media with effusion and recurrent acute otitis media. The analysis involved 54 publications, with 29 studies describing the results of 16 RCTs and another 24 studies reporting the results of 24 non-randomized controlled trials. The authors reported that children with chronic otitis media with effusion who were treated with tympanostomy tubes had a net decrease in mean hearing threshold vs. watchful waiting of 9.1 dB at 1 to 3 months and 0.0 dB at 12 to 24 months. They noted that children with recurrent acute otitis media may have fewer episodes after placement of tympanostomy tubes. Finally, they found that adverse events are associated with tympanostomy tube placement are poorly defined and reported. They concluded,
Tympanostomy tubes improve hearing at 1 to 3 months compared with watchful waiting, with no evidence of benefit by 12 to 24 months. Children with recurrent acute otitis media may have fewer episodes after tympanostomy tube placement, but the evidence base is severely limited. The benefits of tympanostomy tubes must be weighed against a variety of associated adverse events.
In 2021 Hoberman reported the results of an RCT involving 250 children between 6 and 35 months of age with recurrent AOM assigned to treatment with either tympanostomy tubes (n=129) or medical management (n=121). At the end of the 2-year follow-up period, 208 participants had completed the trial, with 13 (10%) participants in the tube group not undergoing their procedure. In the medical group, 54 (45%) participants subsequently underwent tube placement procedures; 35 (29%) of whom received tube placement according to protocol due to recurrence of AOM and 19 (16%) at the request of the parent. The authors reported their results using a per protocol analysis that included in the tube group the 35 participants from the medical group who underwent tube placement. The primary outcome, rate of occurrence of AOM during the study period, was not significantly different between groups (p=0.66). Similarly, no significant differences between groups were found with regard to secondary outcomes, including percentage of episodes of AOM categorized as ‘probably severe,’ the percentage of children who had protocol-defined diarrhea or medication-related diaper dermatitis, extent of antimicrobial resistance, quality of life, use of medical and nonmedical resources, or parental satisfaction with the treatment assignment. Significant differences were reported in favor of the tube group for fewer days per year with otitis-related symptoms other than tube otorrhea, and fewer days per year receiving systemic antimicrobial treatment (no p-values provided). In the medical group, 55 participants met treatment failure criteria. An analysis of this group found them to be younger at baseline than the 46 medical group participants who did not experience treatment failure nor underwent subsequent tube placement. The authors concluded, “Among children 6 to 35 months of age with recurrent acute otitis media, the rate of episodes of acute otitis media during a 2-year period was not significantly lower with tympanostomy-tube placement than with medical management.”
Almari (2024) conducted a meta-analysis to evaluate the effectiveness of tympanostomy with adenoidectomy versus tympanostomy alone in children with OME. Five studies were included in the analysis, which showed that tympanostomy with adenoidectomy significantly improves hearing levels in both ears compared to tympanostomy alone (SMD -0.17, 95% CI [-0.29, -0.05], p=0.005). However, the pooled results were not heterogeneous (p<0.25, F=24%). The authors concluded that tympanostomy with adenoidectomy improves hearing more than tympanostomy alone, but both treatments have similar effects on ear infection rates. Further prospective randomized trials are necessary to evaluate the overall health benefits and long-term outcomes of adding adenoidectomy to tympanostomy tube insertion.
McCoul et al. (2012) provide a well-described, initial validation of the Eustachian Tube Dysfunction Questionnaire (ETDQ-7) as a brief, disease-specific patient reported outcome (PRO) for adult eustachian tube dysfunction (ETD), showing acceptable internal consistency, good test-retest reliability, and strong discrimination between clearly defined ETD and non-ETD clinic participants. However, the small sample, use of tympanometry as an imperfect reference standard, and very high diagnostic accuracy suggest that ETDQ-7 should be viewed primarily as a symptom and outcome measure, not a definitive diagnostic test. Later studies generally support its validity, reliability, and responsiveness across BDET trials, but they also indicated more modest diagnostic performance and limitations in distinguishing ETD subtypes. Holm (2025) subsequently reported a prospective observational study of 75 adults with symptoms suggestive of ETD and objective signs of negative middle ear pressure using the ETDQ-7. Ventilation tube insertion was performed on the affected ears; ETDQ-7 and before and 1 month after ventilation tube insertion were compared to 75 healthy controls. The results showed that the mean ETDQ-7 score decreased from 31.9 to 15.8 (p<0.0001), remained stable on unaffected ears, and was 9.6 in controls. A minimal clinically important difference was achieved on all affected ears after ventilation tube insertion. A cut-off score of greater than 14.5 for diagnosing ETD yielded 100% sensitivity and 94.2% specificity for ETDQ-7. The study was limited by the use of negative middle ear pressure as a diagnostic standard for ETD, this could have inflated sensitivity and specificity, since ETDQ-7 captures symptoms while the reference standard captures only a subset of ETD presentations. Additionally, there was no sham or untreated ETD comparison arm and a short follow-up period of only 1-month after tube insertion. The authors concluded that the study presents encouraging evidence that ETDQ-7 is responsive to treatment, dependable, and capable of distinguishing ETD participants from healthy controls, but the diagnostic accuracy claims are likely inflated due to design limitations, particularly the use of healthy controls and a narrow objective definition of ETD. The results support ETDQ-7 as a symptom severity and outcome measure, not a definitive diagnostic tool. Longer-term follow-up, broader ETD phenotypes, methodologically rigorous design and ear-level scoring are needed to strengthen future evidence.
The procedure to place a tympanostomy tube is commonly performed in an operating room (OR) under general anesthesia. However, in 2019, a device intended to create a myringotomy and insert a tympanostomy tube under local anesthesia in a clinician’s office (Tula® Tympanostomy System) was approved by the FDA. The device was approved for use in adults and in pediatric individuals aged 6 months and older. Soon after, a similar device, the Hummingbird® Tympanostomy Tube System, was cleared for use in children 6-24 months old. Advantages of these devices include avoiding of the need for general anesthesia for tube placement. Risks may include inadequate local anesthesia, dizziness and other common tympanostomy procedure risks such as otorrhea and tympanosclerosis. Prospective, multicenter studies have demonstrated success rates of at least 90% for in-office tympanostomy tube procedures (Truitt, 2021; Zeiders, 2015). In selected individuals with AOM who have normal ear anatomy and can avoid excessive movement, the in-office procedure provides a reasonable alternative to inpatient tympanostomy tube insertion. The AAO-HNS concurs in their 2019 statement on in-office placement of tubes:
The position of the AAO-HNS is that tympanostomy tubes are safe and effective for managing otitis media in children who meet current guidelines for tube insertion [Rosenfeld 2013]. Although insertion of tympanostomy tubes in children is generally accomplished in the operating room under general anesthesia, insertion in the clinic in appropriately selected patients using shared decision making between clinicians and families can be appropriate.
The use of myringotomy alone is poorly studied in the medical literature. In most circumstances, there is no available evidence to demonstrate that the use of myringotomy without tube insertion has any incremental benefit over myringotomy with tube insertion for the treatment of OME or AOM; to the contrary, there is limited published literature indicating that it is inferior for these indications (Mandel, 1992). The use of tubes in conjunction with myringotomy in circumstances where myringotomy alone has been proposed adds longer-term benefits such as prolonged ventilation and drainage, and pressure release. Further, middle ear fluid cultures are generally considered unnecessary when planning or adjusting antibiotic choices, and could be accomplished via less invasive procedures, if required. However, there are some isolated circumstances where myringotomy alone may be warranted. Such circumstances may include when an individual’s tympanic membrane is inflamed to the point where tube placement is not possible or in neonates when tube placement presents too great a risk. Other instances for myringotomy alone may be presented in individuals who are immunocompromised and who may present with advanced OM requiring immediate treatment or to obtain cultures to identify the infectious agent.
