The cost of sinusitis surgery needs to be determined on a case-by-case basis. At present, most sinusitis surgeries use functional endoscopic sinus surgery, and the total cost of preoperative evaluation and related examinations, intraoperative supplies, and postoperative care and related examinations is about 10,000 to 15,000, but the cost of surgery varies depending on the condition and the medical institution chosen. If sinusitis is not accompanied by nasal polyps, drug treatment is preferred, such as intranasal application of decongestants and glucocorticoids, oral antibiotics, etc. If drug treatment does not improve, surgery can be considered; if sinusitis is accompanied by nasal polyps or abnormal nasal anatomy, surgery is preferred. Surgical treatment is divided into nasal surgery and sinus surgery. Deviated septum, vesicular middle turbinate, middle nasal tract polyps, hypertrophic rhinitis, nasal foreign bodies and tumors are the causes of obstruction in the sinonasal complex area, which must be corrected or removed by nasal surgery, which aims to lift the obstruction of the sinonasal complex and improve sinus drainage and ventilation. Sinus surgery can be divided into traditional surgery and nasal endoscopic surgery, and nasal endoscopic surgery has become mainstream in rhinology. The key to surgery is to remove the obstruction of nasal and sinus drainage and ventilation, and to preserve as much as possible the basic structures of the nasal cavity and sinuses, such as the middle turbinate, the normal mucosa of the sinuses and the diseased mucosa that can be benignly transferred, with the aim of maintaining and restoring the physiological function of the nasal cavity and sinuses. The cost of surgery varies depending on the condition and the medical institution chosen, and it is necessary to consult the specific medical institution for the specific cost.
