Introduction To The Functions Of Otorhinolaryngology Endoscopy

A nasal endoscope is an indispensable instrument for endoscopic nasal surgery. Endoscopic nasal surgery is performed under the guidance of a nasal endoscope in the nasal cavity and sinuses. It offers advantages such as excellent illumination and precise surgery, reducing unnecessary surgical trauma. Endoscopic nasal surgery is mainly used to treat chronic sinusitis, nasal polyps, removal of benign nasal tumors, management of nasal bleeding, repair of nasal trauma, and as an adjunct treatment for paranasal and middle ear diseases.

Nose endoscopy, also known as functional endoscopy, is a newly developed technology. It is most commonly used to treat nasal diseases such as nasal polyps, sinusitis, allergic rhinitis, paranasal sinusitis, and nasal cysts, with a success rate exceeding 98%. Compared to traditional surgery, it offers advantages such as being painless, minimally invasive, having a faster recovery, and providing better results.

The application of nasal endoscopy represents a revolutionary advancement in the field of rhinology, a completely new technology. With the aid of the excellent illumination provided by an endoscope, traditional destructive surgery has been transformed into a procedure that, while thoroughly removing lesions, preserves the normal structure of the nasal cavity and paranasal sinuses, ensuring good ventilation and drainage, and maintaining the normal morphology and function of the nasal and sinus mucosa. Its application has expanded to research fields such as the ear, nose, pharynx, larynx, head, and neck.

Nose endoscopy, also known as functional endoscopic sinus surgery, utilizes the excellent illumination of an endoscope and appropriate surgical instruments to make the surgery more precise. The procedure is performed inside the nostrils, without incisions in the nose or face. It is a surgical technique that can remove disease while preserving normal physiological function. It transforms traditional radical or complete curettage of the sinus mucosa into a functional surgery that, while removing lesions, preserves as much of the normal mucosa and structure of the nasal cavity and sinuses as possible, ensuring good ventilation and drainage, and promoting the restoration of the morphology and physiological function of the nasal and sinus mucosa. Depending on the severity of the lesion, the recovery of the nasal cavity and sinuses' own physiological function can achieve the desired therapeutic effect.

Because of its strong light-guiding ability, wide angle, and broad field of view, nasal endoscopes can directly visualize many important areas within the nasal cavity, such as the openings of the sinuses, the grooves, hidden narrowings within the sinuses, and subtle lesions in the nasopharynx. In addition to surgical treatment, simultaneous imaging can be performed to preserve data for consultations, teaching demonstrations, and research summaries. This method has advantages such as minimal trauma, less pain during and after surgery, thorough surgery, and precise operation. Nasal endoscopic surgery can not only remove rhinitis, sinusitis, and nasal polyps, but also simultaneously correct nasal septum deviation and remove vocal cord polyps, thus reducing the postoperative recurrence rate.
