A submucous resection is a surgical procedure used to correct a deviated septum. The deviated septum refers to the misalignment of the wall between the nostrils, which can cause breathing difficulties and other nasal problems. During a submucous resection, the surgeon removes or reshapes the deviated portion of the septum to improve nasal airflow and alleviate symptoms. This procedure is commonly performed to address nasal obstruction and is considered a more conservative approach compared to a full rhinoplasty, which involves reshaping the external nose for cosmetic purposes.Rate this question:

952. Which sinus is entered during an intranasal antrostomy (antral window)?
- A.
Ethmoid
- B.
Sphenoid
- C.
Maxillary
- D.
Frontal
Correct Answer
C. MaxillaryExplanation
During an intranasal antrostomy (antral window), the maxillary sinus is entered. This procedure involves creating an opening in the maxillary sinus to provide drainage and relieve symptoms of sinusitis or other sinus-related conditions. By entering the maxillary sinus, the surgeon can remove any blockages or infected material, improving the patient's symptoms and promoting healing. The ethmoid, sphenoid, and frontal sinuses are not entered during this specific procedure.Rate this question:

- D.
Nasal snare
Correct Answer
D. Nasal snareExplanation
Nasal polyps are growths that occur in the nasal cavity. They can cause symptoms such as nasal congestion, runny nose, and difficulty breathing. In order to remove nasal polyps, a medical instrument called a nasal snare is commonly used. The nasal snare is a looped wire that is inserted into the nasal cavity and used to grasp and remove the polyps. This method allows for precise and controlled removal of the polyps, reducing the risk of damage to surrounding tissues. Therefore, the correct answer is nasal snare.Rate this question:

Frontal sinus trephination
Correct Answer
A. Caldwell-LucExplanation
Caldwell-Luc surgery is a procedure that involves making an incision under the upper lip above the teeth. This surgery is typically performed to treat certain conditions of the maxillary sinus, such as chronic sinusitis or the removal of cysts or tumors. The incision allows access to the maxillary sinus, which is located in the cheekbone area, and allows for the removal of diseased tissue or the drainage of fluid.Rate this question:

954. Which of the following medications would be used as a topical anesthetic before nasal surgery?
- A.
Numorphan
- B.
Codeine
- C.
Cocaine
- D.
Marcaine
Correct Answer
C. CocaineExplanation
Cocaine is commonly used as a topical anesthetic before nasal surgery because it has vasoconstrictive properties, meaning it constricts blood vessels, reducing bleeding during the procedure. It also has local anesthetic properties, numbing the area and providing pain relief. This makes it an effective choice for nasal surgeries where precision and minimal bleeding are important. Numorphan, codeine, and Marcaine are not typically used as topical anesthetics before nasal surgery.Rate this question:
