Follow-Up. Eventually, the tubes fall out as the hole in the eardrum closes. This may happen after several months or more than a year later. It is painless. In fact, the patient and parents may not even be aware that the tubes are out.

Twenty to 50% of children may have OME relapse and require additional surgery that involves adenoidectomy and myringotomy. Tube reinsertion may be recommended for children younger than 4 years of age.

Myringotomy

Myringotomy is used to drain the fluid and may be used (with or without ear tube insertion) in combination with adenoidectomy as a repeat surgical procedure if initial tympanostomy is not successful. It is not effective as a sole surgical procedure. Myringotomy involves the following steps:

• The surgeon makes a very small incision in the eardrum
• Fluid is sucked out using a vacuum-like device
• The fluid is usually examined for identifying specific bacteria
• The eardrum heals in about a week

Adenoid Removal

---

Adenoids are collections of spongy lymph tissue in the back of the throat, similiar to the tonsils. Removal of the adenoids, called adenoidectomy, is usually only considered for OME if a pre-existing condition exists such as chronic sinusitis, nasal obstruction, or chronic adenoiditis (inflammation of the adenoids). Unless these conditions exist, adenoidectomy is not recommended for treatment of OME.

Adenoidectomy plus myringotomy (removal of fluid) may be performed if an initial tympanostomy (tube insertion) procedure is unsuccessful in resolving OME. This combination procedure works best in children aged 4 years or older. Tube insertion is recommended for children under 4 years of age. It is not necessary to perform an adenoidectomy along with tube insertion for children under 4 years of age.

Laser-Assisted Myringotomy

Laser-assisted myringotomy is a technique that is being investigated as an alternative to conventional tympanostomy and myringotomy. At present, there is not enough evidence to determine how well it works in comparison to standard surgical procedures. Some clinical trials have suggested that the success rate for laser-assisted myringotomy is half that of standard tympanostomy/myringotomy. Many insurance companies consider laser-assisted myringotomy to be an investigational procedure and will not pay for it.
