Anesthesia is usually general anesthesia, the second is local anesthesia, some hospitals have local anesthesia plus some intensive anesthesia, basically it is general anesthesia and local anesthesia. In general, general anesthesia is routinely recommended if the patient has sinusitis and nasal polyps all over the nose. During general anesthesia, the anesthesiologist is required to control the blood pressure at the ideal level, which is called controlled hypotension, so as to ensure less bleeding during the operation, and the safety factor of the operation is also larger, and the field of vision is clearer, so that the effect of the operation is better. Local anesthesia may be if the whole group of sinusitis, the first easy to bleed, the second pain tolerance is not enough, so generally the whole group of sinusitis nasal polyp patients recommended general anesthesia surgery. If a single small polyp of the middle nasal tract, sinusitis does not involve too much, so you can local anesthesia, you can take the operation of the nasal mucosa of the local infiltration, the operation can be nerve block, but also can achieve a very ideal operation, postoperative recovery is also good.
