Surgical Outcomes for Petrous Apex Lesions by Anatomical Location and Approach

Tianyang Wu's dataset, uploaded to figshare in March 2026, contains a descriptive analysis of perioperative outcomes for 27 patients with petrous apex lesions. The data compares outcomes for three surgical approaches—Kawase, endoscope-assisted retrosigmoid, and pterional—based on the lesion's anatomical subregion. The study is a single-center, retrospective analysis with a limited sample size.

Use Cases

• Compare gross total resection rates and complication profiles based on surgical approach.
• Analyze the association between anatomical lesion location and specific postoperative risks.
• Investigate outcome differences for a predominant pathology (meningioma) across different surgical approaches.
• Evaluate the trade-offs between operative time, tissue trauma, and cranial nerve dysfunction for different techniques.

Strengths

• Data includes a direct comparison of three distinct surgical approaches (Kawase, retrosigmoid, pterional).
• Analysis is stratified by anatomical subregion (anteromedial, posterior, superoanterior) and includes a subgroup analysis for meningioma (n=20).
• Specific outcome metrics are reported, such as gross total resection rate (100% for Kawase) and cranial nerve injury rates (e.g., 50% trigeminal nerve injury for pterional).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The study is a single-center, retrospective analysis with a limited sample size (27 patients), as noted by the author.
