Antrochoanal polyps (ACP) are benign lesions that arise from the mucosa of the maxillary sinus, grow into the maxillary sinus and reach the choana, and nasal obstruction being their main symptom. It is an interesting model to compare the pathophysiological mechanisms with those of bilateral nasal polyposis (NP).
Is Antrochoanal polyp cancerous?
The antrochoanal polyp, a benign solitary polypoid lesion, usually originates in a maxillary sinus, filling and enlarging the sinus cavity with no bone destruction. It passes through the ostium of the sinus into the choana, and from there into the posterior nasopharynx.
How can you tell the difference between an Antrochoanal polyp and an Ethmoidal polyp?
DIFFERENCIATE BETWEEN ANTROCHOANAL AND ETHMOIDAL POLYPS
| Antrochoanal Polyps | Ethmoidal Polyps |
|---|---|
| Clinical symptoms: Nasal discharge is unilateral, mucopurulent and occasionally blood stained. | Clinical symptoms: Nasal discharge in bilateral watery, accompanied by sneezing epiphora. |
Where can an Antrochoanal polyp be found?
Antrochoanal polyps (ACP) are solitary sinonasal polyps that arise within the maxillary sinus. They pass to the nasopharynx through the sinus ostium and posterior nasal cavity, enlarging the latter two.
What causes Antrochoanal polyp?
Although the etiology of antrochoanal polyps remains unknown, some authors have implicated allergic or inflammatory causes. Chronic sinusitis and cystic fibrosis also have been implicated.
How does Antrochoanal polyp grows posteriorly?
Antrochoanal polyp is a benign lesion originating from the mucosa of the maxillary sinus, growing through the accessory ostium into the middle meatus and, thereafter, protruding posteriorly to the choana and nasopharynx. Incomplete excision of antrochoanal polyp almost always leads to recurrence.
How common is Antrochoanal polyp?
The antrochoanal polyp is an inflammatory nasal polyp found more frequently in children than adults. It represents up to 42% of all nasal polyps in children and 4-6% in adults.
Is Antrochoanal polyp unilateral?
Antrochoanal polyps (ACPs) are benign polypoid lesions arising from the maxillary antrum and they extend into the choana. They occur more commonly in children and young adults, and they are almost always unilateral.
How successful is endoscopic sinus surgery?
In fact, endoscopic sinus surgery, which is the most common type of sinus surgery performed today, is about 85 to 90 percent effective. During endoscopic sinus surgery, the surgeon looks directly into your nose and sinuses through a narrow tube called an endoscope.
What is Ethmoidal polyp?
Ethmoidal polyps are multiple, bilateral, painless, pearly white, grape like masses arising from the ethmoidal air cells. Ethmoidal air cells are multiple air cells present on medial to the eyes.
Can you see nasal polyps on CT scan?
CT scanning also will tell if the polyps are coming from the nose or from the sinuses. Nasal polyps almost always occur on both sides. If a polyp is seen only on one side, a CT scan should be done to make sure that the growth is not something more serious. The scan also can accurately show the size of the growth.
Are polyps benign?
A polyp is a projection (growth) of tissue from the inner lining of the colon into the lumen (hollow center) of the colon. Different types of polyps look different under the microscope. Polyps are benign (non-cancerous) growths, but cancer can start in some types of polyps.
What is a Rhinolith?
Rhinolith (from the Greek rhino meaning nose, and lithos meaning stone) are rare. They are calcareous concretions that are formed by the deposition of salts on an intranasal foreign body.
What is the antrum sinus?
The maxillary sinus (or antrum of Highmore) is a paired pyramid-shaped paranasal sinus within the maxillary bone which drains via the maxillary ostium into the infundibulum, then through hiatus semilunaris into the middle meatus. It is the largest of the paranasal sinuses.
How do you permanently get rid of nasal polyps?
The treatment goal for nasal polyps is to reduce their size or eliminate them. Medications are usually the first approach. Surgery may sometimes be needed, but it may not provide a permanent solution because polyps tend to recur.
How do you get rid of an Antrochoanal polyp?
The current treatment of antrochoanal polyp is simple avulsion of the nasal part with or without removal of the antral part. The antral part is removed through a Caldwell- Luc antrostomy, inferior meatal antrostomy, or middle meatal antrostomy.
What happens if nasal polyps go untreated?
If polyps go untreated for a long period of time, the constant pressure can lead to widening of the nose and the space between the eyes.” Symptoms of nasal polyps can include: a runny or stuffed up nose, sneezing, a loss of taste or smell, snoring, headaches and, in some cases, pain.
Do nasal polyps need to be removed?
Larger growths or groups of nasal polyps can block your nasal passages or lead to breathing problems, a lost sense of smell and frequent infections. Nasal polyps can affect anyone, but they’re more common in adults. Medications can often shrink or eliminate nasal polyps, but surgery is sometimes needed to remove them.
How is functional endoscopic sinus surgery performed?
In a FESS procedure, the surgeon uses a magnifying endoscope to see and remove affected tissue and bone. Before FESS, surgeons cut directly into the outside of the face to find the problem and remove it, increasing infection risk and recovery time.
What is the cost of nasal polyp surgery?
On MDsave, the cost of a Nasal Polypectomy ranges from $2,557 to $3,093. Those on high deductible health plans or without insurance can save when they buy their procedure upfront through MDsave.
Where is the Choana located?
posterior nasal apertures The choanae (singular choana), posterior nasal apertures or internal nostrils are two openings found at the back of the nasal passage between the nasal cavity and the throat in tetrapods, including humans and other mammals (as well as crocodilians and most skinks).
What is ENT fess surgery?
Functional endoscopic sinus surgery (FESS) is a minimally invasive procedure which uses nasal endoscopes to enlarge the nasal drainage pathways of the paranasal sinuses to improve sinus ventilation and allow access of topical medications.
What is the recovery time for nasal polyp surgery?
In conclusion, the average time for recovery from Nasal Polyp Surgery is about two weeks. If you follow these tips you should quickly be able to return to your normal activities. Most patients notice better breathing soon after surgery. It is important to attend your scheduled follow-ups after the procedure.
What does polyps look like in the nose?
A nasal polyp is a clump of cells that forms inside your nasal passage or sinuses. The shape of the clump resembles a grape on a stalk (also called a pedunculated polyp). The color of the polyp can vary: appearing grey,yellow or pink. The size of the polyp can also vary.
What is Ostiomeatal complex?
The ostiomeatal complex (OMC) or ostiomeatal unit (OMU), sometimes less correctly spelled as osteomeatal complex, is a common channel that links the frontal sinus, anterior ethmoid air cells and the maxillary sinus to the middle meatus, allowing airflow and mucociliary drainage.
What are the symptoms of atrophic rhinitis?
Atrophic rhinitis is a chronic condition characterized by symptoms of nasal crusting, purulent discharge, nasal obstruction, and halitosis. Primary atrophic rhinitis is most prevalent in areas with prolonged warm seasons, including south Asia and the Middle East and is more common in women.
What is a polypectomy in medical terms?
Polypectomy is the removal of a polyp. The most common types of polypectomy are uterine polypectomy and colon polypectomy. However, a polypectomy can be performed on any area of the body that develops polyps, such as the nose or stomach. A polyp is a growth that begins in the tissue and extends into the hollow space.
What to expect after having nasal polyps removed?
You may experience pain and some bleeding from the nose for the next three to five days. Most people report feeling weak in the first week after the surgery. You may need to take at least a week off from your work to recover after nasal polyp removal.
What is removed during sinus surgery?
Surgery involves enlarging the openings between the sinuses and the inside of the nose so air can get in and drainage can get out. It may involve removing infected sinus tissue, bone or polyps.
How painful is endoscopic sinus surgery?
Pain: You should expect some nasal and sinus pressure and pain for the first several days after surgery. This may feel like a sinus infection or a dull ache in your sinuses. Extra-strength Tylenol is often all that is needed for mild post-operative discomfort.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
