Summary
This study presents a novel unilateral endoscopic endonasal approach for resecting intracranial dermoid cysts. This minimally invasive technique offers a viable alternative for specific anterior cranial fossa lesions, avoiding complications like anosmia.
Area of Science:
- Neurosurgery
- Otolaryngology
- Pathology
Background:
- Intracranial dermoid cysts are congenital tumors typically found in midline anterior cranial fossa regions.
- Traditional surgical resection often involves craniotomy, but endoscopic techniques are increasingly adopted.
- Endoscopic approaches, particularly binostril, are common for midline lesions.
Purpose of the Study:
- To describe the successful surgical resection of an intracranial dermoid cyst with significant intracranial extension using a unilateral endonasal endoscopic approach.
- To evaluate the feasibility and safety of this alternative technique for specific anterior cranial fossa dermoid cysts.
Main Methods:
- A case report detailing the surgical procedure for a patient with a 1.5-cm intracranial extension of a dermoid cyst.
- Utilized a unilateral endonasal endoscopic approach for cyst resection.
- Monitored for complications, including postoperative anosmia.
Main Results:
- Successful resection of the intracranial dermoid cyst was achieved.
- The unilateral endonasal endoscopic approach resulted in no complications.
- The patient experienced no postoperative anosmia.
Conclusions:
- The unilateral endonasal endoscopic approach is a viable and safe alternative for resecting selected intracranial dermoid cysts, especially those limited to one side of the falx cerebri.
- This technique may offer advantages over traditional craniotomy and standard binostril approaches for specific patient cases.
- Further consideration of this technique is warranted for anterior cranial fossa dermoid cysts amenable to unilateral access.
