Sinusitis and nasal polyps are clinically common and frequent diseases, with an incidence of 1% – 4% of the total population. The impact on the physical and intellectual development of adolescents, on the memory of adults, and on the health of middle-aged and elderly patients caused by the lack of oxygen due to long-term nasal congestion cannot be ignored. Many patients delay effective treatment because of the fear of surgery, and their quality of life is affected to varying degrees. Now is the surgical treatment of sinusitis nasal polyps really still painful? Let’s review the evolution of the surgical approach to such diseases. At the beginning of the last century, the surgical method of nasal polyps is the most traditional removal, doctors use a wire trap from the patient’s nasal cavity to pull the polyp directly to achieve the purpose of removal, the surgical method is simple but rough, very easy to cause damage and injury to the normal structure of the nasal cavity, and the efficacy is not good, easy to recur, the patient feels extremely painful. Later, on this basis, there are a variety of sinus radical surgery, limited to the level of understanding and technical means at the time, to improve the efficacy is at the cost of greater trauma, the patient’s pain is even worse, because this type of surgical methods used for many years, many patients and family members of the current age of sinusitis nasal polyp surgery is still at this stage of knowledge, fear is the most obvious feature. By the 1980s, with the advancement of science and technology and the widespread use of endoscopy, the surgical concept also changed from the traditional radical to the modern functional surgery, and the improvement of efficacy was based on the development of science and technology, and the pain of patients was greatly reduced. From the beginning of this century, with the continuous advancement and development of endoscopic technology, a new surgical approach – minimally invasive surgery – has emerged in the field of surgery based on the previous functional surgery. Minimally invasive surgery for sinusitis and nasal polyps is based on the core of endoscopic technology, changing the action of pulling, tugging and pulling of mucosal forceps commonly used in early surgery, and replacing it with cutting and biting of biting forceps to minimize the damage to the normal mucosa during surgery, and recently, the advanced cut-and-suction system is used, with different angles of cut-and-suction head to protect the normal mucosa while correctly removing the diseased tissue of nasal cavity and sinus with the help of endoscope. With the progress of related science, even the nasal stuffing material used to stop bleeding after surgery has been changed from traditional oil gauze to various new synthetic materials, which further reduces the pain after nasal stuffing. It can be said that nowadays, the patient’s pain during and after the minimally invasive surgery for sinusitis and nasal polyps is incomparable. In the field of rhinology, minimally invasive surgery has been widely used in many surgeries such as refractory rhinorrhea, anterior septal neurectomy, nasal polyp removal, functional sinus surgery, lacrimal sac rhinostomy, cerebrospinal fluid nasal leak repair, and nasal sinus tumor resection, which has completely changed the situation of large incisions, multiple injuries, and different degrees of functional destruction of such diseases. With the maturity and wide application of laser technology, microwave technology and low-temperature plasma technology, the development of minimally invasive technology has provided a broader space. Minimally invasive technology is a surgical technique to cure surgical diseases. It is a new kind of surgery with the help of miniaturized “high-tech” imaging system, which is different from the traditional one, taking into account the radical treatment and paying more attention to the function preservation and recovery. Modern minimally invasive surgery technology is not only an objective need to protect the interests of patients, but also an inevitable trend in the development of surgical technology, and numerous successful clinical experiences have been achieved to show us that the era of minimally invasive surgery has quietly come.
