The endoscope, in combination with the development of sophisticated instruments, has allowed dedicated nasal surgeons to perform increasingly complex nasal operations with a minimally invasive approach. 

This dramatically reduces the side effects which more invasive “open” or external surgical techniques may cause.

Examples:

• Endoscopic surgery for nose bleeds – sphenopalatine artery ligation               
• Endoscopic dacryocystorhinostomy [DCR] – to clear blocked tear ducts
• Endoscopic orbital decompression - cosmetic surgery for correction of prominent eyes which may be associated with overactive thyroid disorders.
• Endoscopic pituitary surgery
• Endoscopic repair of cerebrospinal fluid leaks [CSF leaks]
• Complex endoscopic surgery for frontal sinusitis and mucocoeles
