简介：
Overview
This article describes the microscopic transcanal technique for stapes surgery, providing detailed step-by-step surgical instructions. This minimally invasive approach reduces postoperative pain and avoids the need for larger incisions.
Key Study Components
Area of Science
- Otolaryngology
- Minimally invasive surgery
- Stapes surgery
Background
- The transcanal approach is challenging and requires specialized training.
- It offers advantages such as reduced postoperative pain and no need for retroauricular or endaural incisions.
- Proper patient positioning and instrument handling are crucial for success.
- This technique can be applied to various otologic procedures.
Purpose of Study
- To provide a comprehensive protocol for otologic surgeons.
- To enhance the understanding of the transcanal surgical approach.
- To improve surgical outcomes through detailed instructions.
Methods Used
- Step-by-step surgical instructions for the transcanal approach.
- Use of specialized instruments and techniques for minimal invasiveness.
- Patient positioning in reverse Trendelenburg for optimal access.
- Monitoring of facial nerve during surgery to prevent complications.
Main Results
- Successful application of the transcanal approach in 66 patients.
- Only one patient required a retroauricular incision.
- High preservation rate of the chorda tympani nerve.
- Effective use of prostheses with minimal complications.
Conclusions
- The transcanal approach is effective for various otologic surgeries.
- Proper technique and instrument handling are essential for success.
- This method can lead to improved patient outcomes and satisfaction.
What is the main advantage of the transcanal approach?
The main advantage is its minimally invasive nature, which reduces postoperative pain.
How is the patient positioned for the surgery?
The patient is positioned in a reverse Trendelenburg position with the head tilted towards the contralateral side.
What instruments are used in this technique?
Bent instruments are used to maintain an open working field during the procedure.
What is the significance of facial nerve monitoring?
Facial nerve monitoring is crucial to prevent nerve damage during surgery.
What types of prostheses are commonly used?
Common prostheses include the Richards piston and Matrix Slim Line KURZ prosthesis.
How many patients were included in the study?
The study included 66 patients who underwent stapes surgeries.
What is the importance of cleaning the ear canal?
Cleaning the ear canal is vital to avoid intraoperative infections.
