There are many ways to perform partial inferior turbinate resection, but the ultimate goal is to reduce the turbinates, improve breathing, and enhance the therapeutic effect of medications on rhinitis. With the gradual understanding and emphasis on the physiological function of the nasal cavity and the introduction of new technical means, some procedures have been abandoned, while others are showing great vitality and progressing towards the goal of “preserving the function of the inferior turbinate while reducing it to its optimal size”. Partial inferior turbinate resection and partial mucosal resection of inferior turbinate Partial inferior turbinate resection is a horizontal resection, oblique resection, anterior resection or posterior resection of inferior turbinate according to the surgeon’s judgment, which has a long-lasting effect. Among them, oblique excision can preserve the function of inferior turbinate to the greatest extent and is more widely used clinically. In recent years, with the use of electric cutters, it is possible to accurately remove part of the mucosa on the lateral side of the inferior turbinate in cases without bony hypertrophy. The effect of the ectopic scar healing after these procedures on the functional composition of the inferior turbinate is not yet clear. 2.Submucosal resection of inferior turbinate An incision is made at the front of the inferior turbinate to free the inferior turbinate bone, partially or completely remove the inferior turbinate bone, reset the mucoperiosteal flap, and then perform compression, which is suitable for cases of inferior turbinate bony hypertrophy. If the inferior turbinate bone is not large but only mucosal hypertrophy, the hypertrophied submucosal tissue can be thinned using a submucosal electric cutter. In those with an elevated inferior turbinate bone, the inferior turbinate fracture can be displaced externally. The advantages of these methods are that they can reduce the volume of inferior turbinate and widen the airflow pathway while preserving the mucosal surface of inferior turbinate intact, and they have less bleeding and fast postoperative recovery, which is considered the best surgical method at present. This procedure includes electrocautery, chemical coagulation, cryosurgery, microwave radiation and microluminescence on the mucosal surface of the inferior turbinate. During the operation, the mucosal surface is directly coagulated, gasified and burned by cold, heat and chemical burns to make the inferior turbinate scarred and reduced. This method is not recommended as it may lead to mucosal atrophy, extensive crusting and even inferior turbinate necrosis at the expense of destroying local mucosal function. 4, inferior turbinate submucosal tissue coagulation Because of the destructive nature of inferior turbinate surface coagulation, more functional surgical methods have been explored clinically: i.e. inferior turbinate submucosal coagulation, such as submucosal radiofrequency ablation and laser thermocoagulation. Through unipolar and bipolar electrodes, probes and optical fibers inserted into the submucosa, energy is released to coagulate the submucosal tissue and cause inferior turbinate wrinkling. Recently, some new techniques such as low-temperature plasma radiofrequency ablation can reduce the thermal damage to the surrounding tissues to a minimum, and C02 laser, KTΒ laser, and HE-YAG laser submucosal coagulation also have better efficacy. Therefore, many scholars believe that submucosal coagulation of inferior turbinate is in line with modern minimally invasive principles, simple operation and satisfactory efficacy, and should be the preferred method of inferior turbinate surgery. 5.Local corticosteroid and sclerotherapy injection of inferior turbinate The submucosal injection of corticosteroid and sclerotherapy of inferior turbinate was once widely used. The main problems of this procedure are short and unstable efficacy, and complications of visual impairment and inferior turbinate necrosis have been reported. This type of approach has now been clinically abandoned.
