简介：
Overview
This protocol describes the removal of congenital cholesteatoma using minimally invasive transcanal endoscopic ear surgery with a two-handed approach and a robotic endoscope holder. The technique demonstrates feasibility in a narrow auditory canal of a three-year-old child.
Key Study Components
Area of Science
- Otolaryngology
- Pediatric surgery
- Endoscopic techniques
Background
- Congenital cholesteatoma can occur in the middle ear cavity.
- This condition may extend from the ossicles to the supratubal recess.
- Minimally invasive techniques are crucial for pediatric patients.
- The use of robotic endoscope holders enhances precision during surgery.
Purpose of Study
- To demonstrate a two-handed endoscopic technique for cholesteatoma removal.
- To assess the feasibility of this approach in a pediatric population.
- To provide a detailed protocol for future surgical applications.
Methods Used
- Insertion of the endoscope into a robotic holder.
- Examination of the tympanic membrane.
- Infiltration of the ear canal to prevent blood accumulation.
- Use of an angled cautery needle to open the tympanic cavity.
Main Results
- The technique allows for effective visualization and access to the cholesteatoma.
- There was no bony erosion observed in the case presented.
- The approach was successful in identifying the malleus neck.
- Minimally invasive methods reduced trauma to surrounding tissues.
Conclusions
- The two-handed endoscopic technique is feasible for pediatric cholesteatoma removal.
- Robotic assistance enhances surgical precision in narrow canals.
- This protocol can serve as a guide for similar future procedures.
What is congenital cholesteatoma?
Congenital cholesteatoma is an abnormal skin growth in the middle ear that can lead to hearing loss and other complications.
Why is a minimally invasive approach preferred?
Minimally invasive techniques reduce recovery time and trauma to surrounding tissues, especially in pediatric patients.
What role does the robotic endoscope holder play?
The robotic endoscope holder stabilizes the endoscope, allowing for better precision and control during surgery.
How does the two-handed technique improve surgery?
The two-handed technique allows for greater dexterity and manipulation of instruments in confined spaces.
What are the potential complications of cholesteatoma surgery?
Potential complications include hearing loss, infection, and damage to surrounding structures.
Is this technique applicable to adults?
While this study focuses on pediatric patients, the principles may be adapted for adult cases as well.
