Biofilm Formation on Silicone Tympanostomy Tubes With Polyvinylpyrrolidone Coating

Biofilm formation on silicone tympanostomy tubes with polyvinylpyrrolidone coating.

OBJECTIVE To determine whether biofilm formation on silicone tympanostomy tubes (TTs) is prevented by polyvinylpyrrolidone (PVP) coating. DESIGN In vitro microbiologic study. SUBJECTS Silicone TTs with and without a PVP coating. INTERVENTION The TTs were exposed to blood or phosphate-buffered saline and cultured with Pseudomonas aeruginosa or Staphylococcus aureus. After 4 days, antibioti...

Tympanostomy Tubes

[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 in Children With Otitis Media

Otitis media is often preceded by a viral upper respiratory tract infection that causes Eustachian tube obstruction, negative middle ear pressure, and accumulation of fluid in the normally air-filled space of the middle ear. Acute otitis media (AOM) is defined as the presence of fluid in the middle ear with signs and symptoms of an acute infection, such as fever and ear pain. Otitis media with ...
