Tympanostomy tubes and water

[Tympanostomy tubes and water].

OBJECTIVE An in vitro study was conducted to set the necessary pressure in fluids that could break resistance and cross the opening of a tympanostomy tube. METHODS A water column model was created and graduated in centimeters from base to top. We adapted three sorts of tympanostomy tubes. In each model, fluids were tested (tap water, seawater, river water, soapy water and eardrops). The colum...

Tympanostomy tubes and water exposure: a practical model.

OBJECTIVE To determine whether water exposure causes middle ear contamination in patients with collar button tympanostomy tubes (TTs). METHOD AND DESIGN An in vitro model of a human head that contained an auricle, external auditory canal, tympanic membrane with TT, middle ear, eustachian tube, and mastoid cavity was developed. Two electrodes connected to an external ohmmeter resided in the mi...

Tympanostomy tubes: patient selection and special considerations

Indications for tympanostomy tube (TT) placement in children with chronic serous effusions and hearing loss are fairly well established. The use of TTs for children with recurrent acute otitis media (rAOM) has not been studied as extensively as for those with hearing loss from middle-ear effusions. There is a subset of children who fall outside established guidelines for either of the preceding...

Clinical practice guideline: Tympanostomy tubes in children.

OBJECTIVE Insertion of tympanostomy tubes is the most common ambulatory surgery performed on children in the United States. Tympanostomy tubes are most often inserted because of persistent middle ear fluid, frequent ear infections, or ear infections that persist after antibiotic therapy. Despite the frequency of tympanostomy tube insertion, there are currently no clinical practice guidelines in...
