How are Antrochoanal polyps diagnosed?
Penelope Carter How are Antrochoanal polyps diagnosed?
The gold standard for diagnosing an antrochoanal polyp is a CT scan showing a hypodense mass arising from an enlarged, opacified maxillary sinus. The polyps do not cause bony destruction. However, when large, they can expand and enlarge the ostium.
What is meant by antrochoanal polyp?
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.
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.
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 is antrochoanal polyp treated?
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.
Is antrochoanal polyp cancerous?
Antrochoanal polyps (ACPs) are benign polypoid lesions arising from the maxillary antrum and they extend into the choana. ACPs usually have two components and these are the cystic and solid polypoid parts (1-4).
What does a CT scan show?
CT scans show a slice, or cross-section, of the body. The image shows your bones, organs, and soft tissues more clearly than standard x-rays. CT scans can show a tumor’s shape, size, and location. They can even show the blood vessels that feed the tumor – all without having to cut into the patient.
What is a CT scan of your sinuses?
Computed tomography (CT) of the sinuses uses special x-ray equipment to evaluate the paranasal sinus cavities – hollow, air-filled spaces within the bones of the face surrounding the nasal cavity. CT scanning is painless, noninvasive and accurate.
How long does it take to recover from 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.
When is a CT scan needed?
Your doctor may recommend a CT scan to help: Diagnose muscle and bone disorders, such as bone tumors and fractures. Pinpoint the location of a tumor, infection or blood clot. Guide procedures such as surgery, biopsy and radiation therapy.
How are antrochoanal polyps diagnosed?
The gold standard for diagnosing an antrochoanal polyp is a CT scan showing a hypodense mass arising from an enlarged, opacified maxillary sinus. 3 The polyps do not cause bony destruction. 6 However, when large, they can expand and enlarge the ostium. The location of the polyp and its soft consistency, cause its characteristic dumbbell shape.
What are antiantrochoanal polyps (ACP)?
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.
Can sinus polyps be diagnosed on CT scan?
Comprising nasal mucosa, it originates in the maxillary sinus and can cause symptoms of nasal obstruction. The polyp can be definitively diagnosed on CT. Treatment involves surgery and recurrence is rare if the entire polyp is removed.
Do antrochoanal polyps have a narrow pedicle?
Although pathologically antrochoanal polyps have a narrow pedicle or stalk, this is usually not evident on CT. Occasionally, antrochoanal polyps may have a higher density (and Hounsfield values) if they are long-standing (i.e. desiccated) and/or have an associated fungal infection (see fungal sinusitis) 1.
