Frequently Asked Questions

For medical professionals

1. What is the DALENT Sinusleeve?

The Dalent Sinusleeve is a balloon sinus dilation device (BSD) which provides access to the frontal, sphenoid and maxillary sinuses.  The Sinusleeve acts as a sleeve with the ability to slide over most existing suction devices and other rigid instruments. This allows the surgeon to combine balloon dilation with familiar instrumentation without the requirement for multiple BSD devices. 

2. Which sinuses can be treated with the Sinusleeve?

The Sinusleeve is designed to allow treatment of the frontal, sphenoid and maxillary sinuses.

3. Which instruments are compatible with the Sinusleeve?

The Sinusleeve is compatible with sinus instruments measuring from 7 to 10 FR.

4. What is the dilation size/diameter of the Sinusleeve?

 The Sinusleeve will create up to a 7 mm size dilation. 

5. Can you utilize suction with the Sinusleeve?

Yes, the Sinusleeve will fit over common/conventional sinus surgery suction instruments. This allows for simultaneous suction and dilation during sinus surgery.

6. Where can I use the Sinusleeve?

The Sinusleeve can be used in the operating room or office. The Sinusleeve provides the surgeon with the ability to convert commonly used sinus instruments into a dilation device. This flexibility assists sinus surgeons when performing endoscopic sinus surgery in combination with balloon dilation (also known as a hybrid sinus procedure). The Sinusleeve can also be used for stand-alone balloon dilation procedures.

7. Does the Sinusleeve contain latex?

No, the Sinusleeve is a latex-free device.

8. Who is DALENT Medical?

Dalent Medical is an FDA registered facility and the Sinusleeve is an FDA listed medical device.  The Sinusleeve is manufactured and packaged in the USA.

For Consumers

1. What and where are my sinuses??

The sinuses are air filled spaces with in the bones of our face. Most commonly, there are four pairs of sinuses on each side of the school. They are known as the frontal, maxillary, ethmoid, and sphenoid sinuses. They extend up around our forehead, behind the nose and cheek bones and between the eyes. They are connected to our nose through drainage areas. This keeps the sinuses ventilated and allows for the drainage of mucous and fluid.

2. What is chronic sinusitis? 

Chronic sinusitis is when the sinuses become infected and inflamed resulting in a buildup of fluid, mucous and bacteria in the sinus cavities. This produces symptoms of nasal congestion, facial pain, headache and pressure.

3. What causes sinusitis?

There are several factors which can predispose you to sinusitis. Allergies and upper respiratory infections may result in inflammation and obstruction of the drainage areas connecting the sinuses to the nose. Additionally, chronic thickening of the lining of the drainage areas or nasal polyps may block sinus outflow and lead to build of infection and mucous in the sinuses.

4. How is chronic sinusitis treated?

Sinusitis is commonly treated with medications and antibiotics. Nasal saline irrigations, topical nasal steroid spray, oral antihistamines, and steroids are medications used to help reduce the inflammation caused by sinusitis. Antibiotics are used to treat the infection within the sinus cavities.

5. When is surgery used to treat sinusitis?

Surgery is used to treat sinusitis when medical treatment has failed.

6. How is surgery performed?

Surgery is typically performed through the nose with the aid of a camera known as an endoscope.  The goal of surgery is to restore the ability of the sinuses to drain and alleviate the buildup of mucous and fluid. This can be done with the use of hand held cutting and powered instruments (known as endoscopic sinus surgery) or dilation of the sinus drainage areas via the use of balloon dilation.

7. What type of surgery is best for my sinuses?

The best treatment for your sinuses depends on the underlying cause of your sinusitis. This is determined by your otolaryngologist/ENT surgeon. If your sinusitis is able to be treated with balloon dilation utilizing the sinusleeve it should result in a short and painless recovery.  The sinusleeve may also be utilized in the office or in conjunction with endoscopic sinus surgery performed in the operating room.
