Most sinusitis surgeries today do not require external incisions and are generally minimally invasive procedures performed endoscopically.
Functional sinus surgery can be performed endoscopically if the sinusitis meets the indications for surgical treatment, mainly through small or localized intranasal surgeries as a means of addressing a wide range of sinus-related diseases.
The goal of functional sinus surgery is to remove diseased tissue, correct defective structures, and restore sinus drainage and ventilation. Sinusitis surgery through endoscopy can achieve the advantages of omnidirectional vision, accurate operation, less trauma, and can maintain normal tissues and structures.
A small number of patients with sinusitis combined with hyperplastic neoplasm and other diseases, may need to make auxiliary incisions in the arch or the oral cavity for joint treatment, but the process of most also need to operate under the nasal endoscopy.
In summary, most diseases of sinusitis can be surgically treated under minimally invasive.
