The fast, gentle way to open your sinuses with a
simple, in-office procedure.
The Vent-Os Sinus Dilation System is a small, low-pressure, self-expanding insert designed to relieve symptoms of sinusitis with a simple procedure. The procedure uses a small capsule-shaped device that is gently placed in your sinus opening. In most patients, the device can be placed in the physician’s office, with local—and often topical—anesthesia. Once in position, it gradually absorbs moisture from the lining of your sinus passage and expands. After an hour, the device is removed and drainage is restored. At the conclusion of the procedure, you may return to normal activities immediately.
How the Vent-Os Sinus Dilation System opens blocked sinuses.

1 | Sinusitis occurs when sinus passages are blocked by swelling or inflammation.
2 | The Vent-Os Sinus Dilation System is a small, capsule-shaped device that your physician temporarily places into the blocked sinus opening.
3 | Once in position, the device absorbs moisture from the sinus passage lining and gradually expands.
4 | The device is then removed, thereby opening the passage, restoring sinus drainage and making it easier for you to breathe. Depending on the severity of your symptoms, your doctor may place and remove the capsule device during your sinus surgery procedure performed in the office.
A proven way to open your sinuses.
Clinical study results for the Vent-Os™ Sinus Dilation System.
The Vent-Os Sinus Dilation System is used for dilation of the maxillary sinus ostia and associated spaces in adults for diagnostic and therapeutic procedures.
In the multicenter study, 93% of the treated sinus passages were found to be open to allow ventilation and drainage of maxillary sinuses after one year post procedure: 1

- 34 patients with chronic sinusitis were treated; 55 sinus passages (ostia) were dilated
- 29 patients received the Vent-Os procedure in conjunction with FESS
- 5 patients received the Vent-Os procedure in-office
- No adverse effects occurred during insertion or removal of the devices
- Immediately post procedure, 95% of passages treated were confirmed visibly open and 5% could not be visualized
- Patients were followed up at 3 months, 6 months and 12 months*
- At 3 months, 33 patients* were available for follow-up and 51/55 (93%) of the treated sinus passages were visibly open, with 4/55 (7%) could not be visualized
-
At 6 months, 29 patients were available for follow-up and 43/47 (91%) of the treated sinus passages were visibly open, with 4/47 (9%) could not be visualized
-
At 12 months, 27 patients were available for follow-up and 42/45 (93%) of the treated sinus passages were visibly opened, with 3/45 (7%) could not be visualized
-
No device related or procedural complications were encountered during the evaluation period
The Vent-Os Sinus Dilation System is intended for use by or under the direction of a physician. The Vent-Os procedure has associated risks, including tissue and mucosal trauma, infection, or possible optic injury. Consult your physician for a full discussion of risks and benefits to determine whether this procedure is right for you.
