Summary
A novel open transnasal surgical approach offers superior access to midline skull base tumors compared to traditional methods. This technique provides wider exposure and preserves mucosal integrity for better postoperative sealing.
Area of Science:
- Neurosurgery
- Otolaryngology
- Skull Base Surgery
Background:
- Transfacial approaches are standard for anterior skull base tumor resection.
- Existing methods like rhinal and sublabial approaches have limitations in exposure and orientation.
Purpose of the Study:
- To introduce and evaluate a new open transnasal surgical technique for accessing the midline skull base and pituitary region.
- To compare the efficacy of this new approach with traditional transfacial methods.
Main Methods:
- The technique was developed based on experience with open septorhinoplasty.
- Initial cadaveric studies were performed, followed by clinical application in 28 patients.
- The approach was used for resecting various midline skull base tumors.
Main Results:
- The open transnasal approach provided wider exposure and a true midline orientation.
- Preservation of the mucosal membrane ensured a better postoperative seal.
- The technique was successfully applied in 28 consecutive patients for tumor resection.
Conclusions:
- The described open transnasal approach is a valuable alternative for midline skull base tumor resection.
- It offers significant advantages over traditional transfacial techniques regarding exposure and postoperative sealing.
