What is middle meatal antrostomy?

Page 1. MIDDLE MEATAL ANTROSTOMY. 1. Definition: Enlargement of the natural opening of the maxillary sinus into the middle meatus.

What is nasal antrostomy?

Maxillary antrostomy is a surgical procedure to enlarge the opening (ostium) of the maxillary sinus. This allows for further surgical intervention within the maxillary sinus cavity as well as improved sinus drainage.

How is nasal antrostomy done?

During surgery, the ENT surgeon passes a narrow tube called an endoscope into your nose. This tube has a tiny camera and a light at the end of it, so the surgeon has an excellent view of your maxillary sinus, the opening to the maxillary sinus, and the area of the nose where it drains (the osteomeatal complex).

What are the complications of Fess?

Complications of FESS LP is a thin bone and can be fractured easily resulting in fat herniation, intra-orbital bleeding and EOM damage. Posteriorly, ON is at risk as it lies in a more medial plane, and closer to the lateral wall of the posterior ethmoid cells (Onodi cells) and sphenoid sinus.

What is middle meatus?

The middle meatus is the nasal passageway that lies between the inferior meatus and the middle meatus. This space is important for: Drainage of three of the paranasal sinuses; the maxillary, frontal, and front (anterior) ethmoid sinuses. Airflow through the paranasal sinuses which creates the tones of our voices.

Can maxillary sinus be cured?

Their study showed that more patients were cured or improved more quickly with antibiotic therapy compared to placebo, but also that two thirds of patients receiving placebo recovered spontaneously. In addition, serious complications of bacterial sinusitis were rare.

What is inferior meatal antrostomy?

An inferior antrostomy provides an alternate pathway of drainage allowing the cilia to become functional. It also helps for polyp disease, thick secretions, large retention cysts, maxillary related choanal polyps or fungal disease removal.

What is a mega antrostomy?

Endoscopic maxillary mega-antrostomy (EMMA) is a mucosal sparing technique that facilitates mucus clearance and sinus irrigation in terminally dysfunctional maxillary sinuses.

What is antrum puncture?

Antral lavage is a largely obsolete surgical procedure in which a cannula is inserted into the maxillary sinus via the inferior meatus to allow irrigation and drainage of the sinus. It is also called proof puncture, as the presence of an infection can be proven during the procedure.

How long is recovery after sinus surgery?

You will probably be able to return to work or school in about 1 week and to your normal routine in about 3 weeks. But this varies with your job and the extent of your surgery. Most people feel normal in 1 to 2 months. You will have to visit your doctor regularly for 3 to 4 months after your surgery.

What is empty nose syndrome?

Empty nose syndrome (ENS) is a rare, late complication of turbinate surgery. The most common clinical symptoms are paradoxical nasal obstruction, nasal dryness and crusting, and a persistent feeling of dyspnea.

Is fess a minor surgery?

Conclusions. We believe that FESS is a safe, effective and fast procedure. In our series the incidence of minor and major complications is 5-10% and 0.34% respectively. We think that performing a revision FESS is more difficult and time demanding than a primary FESS, due to altered anatomy and scarring.

What happened to middle meatal antrostomy in sinus surgery?

As a result, the concept of middle meatal antrostomy fell out of favour. Kennedy (1987) reintroduced endoscopic middle meatal antrostomy in sinus surgery in 1987.

When is a middle meatal antrostomy (MMA) indicated?

Creation of middle meatal antrostomy is sometimes needed for the following cases: biopsy of an antral mass; resection of a maxillary sinus fungal ball or inverted papilloma;

What is the history of the middle meatal antrostomy?

In the early part of the 20thcentury, Siebenmann et al. (1912) advocated a middle meatal antrostomy because of the ease of the approach. However, there was concern about the possibility of permanent damage to the primary vascular, lymphatic and neurological communications if the ostium was traumatized (Proetz 1941).

What are the risks of a middle meatal antrostomy?

over the potential risks of middle meatal scarring, interruption of mucociliary clearance, improper ostial function, development of maxillary recirculation by not including the natural ostia in the middle meatal antrostomy, and the likely need for revision maxillary
