True about septal hematoma is -a) Occurs due to traumab) Can lead to saddle-nose deformityc) Conservative treatmentd) May lead to abscess formation
First, I need to recall what a septal hematoma is. It's a collection of blood in the nasal septum, usually from trauma. So option a) is correct. That's a given. Now, saddle-nose deformity—what causes that? Oh right, it's usually from syphilis or from complications of septal hematomas if not treated. If the hematoma isn't drained, it can lead to necrosis of the septal cartilage, which then collapses, causing the saddle-nose deformity. So option b) is correct.
Option c) says conservative treatment. But septal hematomas need active treatment. If left untreated, they can clot and cause pressure necrosis. So conservative management isn't right; they need incision and drainage. So c) is incorrect.
Option d) mentions abscess formation. If the hematoma becomes infected, it can turn into an abscess. So d) is correct.
So the correct options would be a, b, d. The incorrect one is c. The question is phrased as "True about septal hematoma," so the answer includes a, b, d. But the user might have meant which are true, so the answer is all except c. Let me check the options again. The correct answer is options a, b, d. Therefore, the correct answer is options A, B, D. But the user's correct answer is not specified here. Wait, the user's correct answer is given as A. B. C. D. but the correct answer is supposed to be which options. The original question is in the format where the correct answer is one of the options, but the question is asking which statements are true. Wait, maybe the question is a multiple true/false question, but the user's correct answer is given as a single option. Wait, the user's correct answer is written as "Correct Answer: [Letter]. [Answer Text]" but in the question, the options are a, b, c, d. The user's correct answer is not specified here. Wait, maybe the original question is in a format where multiple options are correct, but the user's correct answer is not provided. Wait, the user provided the question and the correct answer as "Correct Answer: . " but left it blank. Maybe the user intended that the correct answer is all of the above except one. Let me check again.
The options are: a) occurs due to trauma (true), b) can lead to saddle-nose deformity (true), c) conservative treatment (false), d) may lead to abscess formation (true). So the correct answer would include a, b, d. Therefore, the correct answer is options A, B, D. But in the user's setup, the options are labeled A to D, and the correct answer is supposed to be one of them. Wait, this is confusing. The question is phrased as "True about septal hematoma is - a)..." which is a multiple true/false question. But the
