Summary
This study reconstructs surgical paths for Functional Endoscopic Sinus Surgery (FESS) using CT scans. These reconstructions aid in developing robot-assisted sinus surgery simulations.
Area of Science:
- Otorhinolaryngology
- Medical Imaging
- Robotics in Surgery
Background:
- Chronic sinusitis necessitates minimally invasive Functional Endoscopic Sinus Surgery (FESS).
- FESS involves navigating surgical instruments through the nasal cavity to access paranasal sinuses.
Purpose of the Study:
- To reconstruct the surgical paths used in FESS for accessing paranasal sinuses.
- To provide data for Finite Element modeling and simulations in robot-assisted endonasal surgery.
Main Methods:
- Utilized volumetric CT data for 3D reconstruction.
- Developed methods to trace and analyze surgical instrument paths within the nasal cavity.
Main Results:
- Successfully reconstructed the specific paths for approaching each paranasal sinus.
- Generated data suitable for computational modeling and surgical simulation.
Conclusions:
- Path reconstruction from CT data is feasible for FESS.
- The reconstructed paths are valuable for advancing robot-assisted endonasal surgery simulations.

01:30Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

01:29Endoscopic Procedures I: Esophagogastroduodenoscopy
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
During an EGD, the endoscope can be used to:
01:26Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
