Collar Buttons
The symmetry of these devices is inspired by sound engineering principles, this common feature being expressed in differing forms to address a variety of applications, where short-term ventilation is indicated of, say, seven to nine months.

Reuter Bobbins
The shortness of these tubes means that they are highly unlikely to abrade the mucous membrane of the middle ear, which might cause the lumen to become blocked with a blood clot or serum. The unusually wide flanges extend the period of patency, especially when fenestrated, so that tissues of the tympanic membrane may penetrate them to act as stabilizing dowels. For medium-term ventilation, say, twelve to thirteen months.

Jain Vent Tube
A new optimised design, being a small device for better visualisation, with an internal lumen diameter of 1mm, which is suitable for both adults and children!
The angled tab of the outer flange allows a secure and firm grasp, presenting the grommet at the correct angle providing good visibility of the inner flange and making insertion easy and quick even in narrow and tortuous canals. For medium-term ventilation, say, twelve to twenty four months.

Developed for: Dr. Parmod Jain, Poole, Dorset, UK

Shah Ventilation Tubes
This popular pattern affords medium-term ventilation of the middle ear cleft. Its design facilitates insertion through the myringotomy incision and aids retention of the tube, especially if the inner flange points to the head of the malleus. Its duration in situ is typically fifteen to eighteen months.

Reddy Grommet
The unique Reddy Grommet has been used widely for several years. It offers the advantage of a unique grasping feature, which enables the tube to be presented to the incision in the correct orientation. This small tube reduces the risk of tympanosclerosis, while its design assures medium-term ventilation, say, thirteen to fifteen months, especially if the inner flange is pointed towards the head of the malleus.

Bel-Air Ventilation Tube - U.S. Patent No. 5,389,088
This tube:

is narrow at one point only, so less likely to be blocked with exudate
affords good visibility of the middle ear cleft
is easy to insert
remains patent for approximately two years

Developed for: Prof. M. Hageman, Haarlem, The Netherlands

Shah Permavent
The bevelled flange is intended to be cut to the shape best suited to the clinical characteristics presented. The absence of an outer flange aids retention and clinical studies show that this long-term tube which, if deliberately removed, is unlikely to leave a perforation in the tympanum. This tube will ventilate the middle ear for approximately three years.

Exmoor T-Tubes
The absence of an external flange makes premeture extrusion less likely while, being soft and flexible, these tubes are easily shortened to the required size and removal can be readily accomplished, if necessary, by gentle traction. These are long-term ventilation tubes and, in order to minimise the possibility of a residual perforation, they should be deliberately removed.

Donaldson Grommet
This soft silicone product is available in both regular pattern and with a tab to aid insertion. The compressibility of these tubes permits insertion with minimal tympanic trauma. They resume their shapes when released in situ and the design makes for good retention, typically twelve to thirteen months.

Shah Mini Grommet
The Shah Mini Grommet is small enough to be positioned in the anterosuperior quadrant, even via narrow external ear canals. Its size and shape facilitate insertion with minimal trauma. It is appropriate to the treatment of severe 'glue ear' or to maintain equal pressure across a new tympanic graft.
Clinical studies suggest that, if the inner flange is orientated to point towards the head of the malleus, this tube will remain patent typically for five months and, if used as the tube of first choice in cases of otitis media with effusion, a substantial majority would require no further surgical intervention and resultant tympanosclerosis would be minimal.

The Tiny T-Tube will remain patent typically for twelve to fourteen months and is intended to extend the period of ventilation to young ears, with minimal scarring of the tympanum.
