Surgical Outcomes for Benign Parotid Tumors: Meta-Analysis of 23 Studies

Supplementary file 1_Permanent facial palsy and recurrence rate after surgery for benign parotid tumors: pairwise and network meta-analysis of different parotid surgery techniques.docx contains meta-analysis results comparing total parotidectomy, partial parotidectomy, and extracapsular dissection. The dataset aggregates data from 23 studies involving 4,674 adult patients, with a mean follow-up of 66.0 months. It was authored by Caroline Bernhard and published on figshare in May 2026.

Use Cases

• Compare recurrence rates between surgical techniques based on the reported tumor recurrence rate (TRR) metric.
• Analyze permanent facial palsy risk based on the reported facial palsy rate (FPR) metric.
• Perform statistical meta-analysis using arcsine transformed rates and arcsine differences (ASD) as described.
• Evaluate the long-term safety profile of extracapsular dissection versus more invasive procedures.
• Identify gaps in comparative research, such as the lack of studies comparing ECD with TP for FPR.

Strengths

• Aggregates data from 23 studies, providing a substantial sample size of 4,674 patients.
• Includes a mean follow-up period of 66.0 months, allowing for analysis of long-term outcomes.
• Compares three distinct surgical techniques (TP, PP, ECD) using both pairwise and network meta-analysis methods.
• Reports specific average rates: TRR of 2.9% and FPR of 3.0%.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes a lack of studies with long-term follow-up, which may affect the robustness of conclusions.
