Official Description

Nasal endoscopy, surgical, ethmoid sinus, placement of drug eluting implant

Common Language Description

An endoscopic procedure known as nasal endoscopy is performed to examine the ethmoid sinus, which is situated between the eyes. This surgical intervention involves the placement of a drug-eluting implant designed to deliver medication directly to the affected area. The procedure may also include surgical debridement, biopsy of sinus tissue, and the removal of polyps, depending on the specific needs of the patient. The primary indications for this procedure are chronic rhinosinusitis (CRS) and inflammation of the paranasal sinuses and nasal passage lining that persists for more than 12 weeks and does not respond to medical management. The goal of the nasal endoscopy and subsequent implant placement is to restore normal sinus ventilation and drainage, thereby alleviating symptoms associated with sinus obstruction. During the procedure, a rigid or flexible endoscope is inserted through the nasal passage and advanced to the ethmoid sinus. If necessary, polyps are excised using a snare, and tissue samples can be collected with biopsy forceps. The drug-eluting implant, which is a synthetic bio-absorbable device containing a steroid compound, is introduced into the ethmoid sinus using a proprietary endoscopic delivery system. Once in place, the implant expands to fit the sinus cavity, helping to stabilize the middle turbinate, prevent obstructive adhesions, and reduce inflammation. The CPT® Code 0406T encompasses the surgical nasal endoscopy of the ethmoid sinus along with the placement of the drug-eluting implant, while the related code 0407T includes additional procedures such as biopsy, polypectomy, or debridement in conjunction with the implant placement.

1. Indications

The indications for performing nasal endoscopy with the placement of a drug-eluting implant include the following:

Chronic Rhinosinusitis (CRS) - A condition characterized by prolonged inflammation of the nasal and sinus mucosa lasting longer than 12 weeks, which is unresponsive to medical management.
Inflammation of the Paranasal Sinuses - Persistent inflammation affecting the sinuses that may lead to obstruction and other complications.
Nasal Passage Lining Inflammation - Ongoing inflammation of the nasal lining that contributes to symptoms of nasal obstruction and sinus pressure.

2. Procedure

The procedure involves several key steps to ensure effective examination and treatment of the ethmoid sinus:

Step 1: Endoscope Insertion - A rigid or flexible endoscope is carefully inserted through the nostril and advanced to the ethmoid sinus. This allows the physician to visualize the sinus cavity and assess any abnormalities.
Step 2: Surgical Debridement and Biopsy (if indicated) - If necessary, the physician may perform surgical debridement to remove diseased tissue or polyps. Additionally, tissue samples can be obtained using biopsy forceps for further analysis.
Step 3: Implant Placement - A synthetic bio-absorbable implant containing a steroid compound is introduced into the ethmoid sinus through a proprietary endoscopic delivery system. This step is crucial for delivering medication directly to the site of inflammation.
Step 4: Implant Expansion - Upon delivery, the implant expands and conforms to the contours of the sinus cavity. This expansion helps stabilize the middle turbinate, which is essential for preventing obstructive adhesions and reducing swelling in the sinus area.

3. Post-Procedure

After the procedure, patients may experience some discomfort or nasal congestion as part of the recovery process. It is important for healthcare providers to monitor the patient's response to the implant and assess for any potential complications. Follow-up appointments may be scheduled to evaluate the effectiveness of the treatment and to ensure proper healing of the sinus tissues. Patients are typically advised on post-operative care, which may include instructions on nasal hygiene and the use of saline sprays to promote healing and maintain sinus patency.
