Pacific Rim Master Class 2023

Pacific Rim Master Class in Endoscopic Endonasal and Keyhole Surgery

A collaboration between University of Colorado & Pacific Neuroscience Institute

March 24-26, 2023 | Santa Monica, California, USA

This endoscopic endonasal and keyhole surgery CME course will provide an extensive immersion in advanced endonasal and transcranial keyhole surgical techniques using didactic and anatomical lectures, cadaveric dissections, and a live surgery on Day 1.

The course faculty are highly experienced and recognized world-experts in minimally invasive endoscopic and keyhole surgery.

The course emphasis will be on:

  • Patient and approach selection
  • Surgical judgement
  • Anatomical awareness
  • Technical nuances
  • Complication avoidance
  • Maintaining quality of life
  • Optimizing clinical outcomes

Specific approaches discussed and performed in the lab will include:

  • Endoscopic endonasal route including extended approach variations
  • Supraorbital eyebrow craniotomy
  • Mini-pterional craniotomy
  • Gravity-assisted transfalcine and transtentorial endoscopic approaches
  • Retromastoid route

A team approach involving neurosurgery, otolaryngology and neuro-ophthalmology will be stressed as well as collaboration with neuro-oncology, endocrinology and radiation oncology.

The course will have parallel sessions on keyhole surgery for neurosurgeons, and endonasal approaches for ENTs/ophthalmologists.


Neurosurgeons, otolaryngologists/ENT/rhinologists, plastic surgeons, and neuroophthalmologists/ ophthalmologists with some prior experience in endoscopic and keyhole surgery who want to expand their repertoire and capabilities.
