  Purpose

There are different kinds of ear tubes that may be inserted into the tympanic membrane to relieve recurrent acute otitis and hearing impairment due to otitis media with effusion. The tubes differ in size, shape and material.

No-one knows if there are differences between the different kinds of tubes regarding complications.

The investigators' hypothesis is that there is differences between the different kinds of tubes regarding complications.

To test the investigators' hypothesis, the investigators are about to conduct a randomized controlled study of four kinds of tubes having two different material and two different shapes.

Further study details as provided by Danderyd Hospital:

Primary Outcome Measures:
  • Time to complete expulsion of the ventilation tube from the tympanic membrane [ Time Frame: 45 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Persistent tympanic membrane perforation [ Time Frame: 45 months ] [ Designated as safety issue: No ]
  • Need for tube extraction (pain or infection) [ Time Frame: 45 months ] [ Designated as safety issue: No ]
  • Pain leading to health care contact [ Time Frame: 45 months ] [ Designated as safety issue: No ]
  • Tube related ear infection [ Time Frame: 45 months ] [ Designated as safety issue: No ]
  • Obstruction of the tube [ Time Frame: 45 months ] [ Designated as safety issue: No ]
  • Presence of myringosclerosis [ Time Frame: 45 months ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: 1 Device: Insertion of a specific type of ventilation tube through the tympanic membrane

The ventilation tubes are tested using one type in one ear and another type as an active comparator in the other ear.

The investigators will test in total 4 different kinds of tubes. Four different combinations of tubes will be tested.

The first combination will test:

"Shepard tube" (double flanged, Fluoroplastic) vs "Donaldson tube" (double flanged, silicone)

The second combination will test:

"Straight tube" (single flanged, Fluoroplastic) vs "Armstrong" (single flanged, silicone)

The third combination will test:

"Armstrong" (single flanged, silicone) vs "Donaldson tube" (double flanged, silicone)

The fourth combination will test:

"Straight tube" (single flanged, Fluoroplastic) vs "Shepard tube" (double flanged, Fluoroplastic)
