Orthognathic Surgery Cases with PONV Risk Factors, 2014-2024

A retrospective observational study of 667 orthognathic surgery cases from 632 patients treated at a single department between 2014 and 2024. The dataset, created by Takuma Watanabe, examines associations between clinical variables and postoperative nausea and vomiting (PONV). It includes patient demographics, surgical details, and outcomes, with descriptive statistics and logistic regression results provided.

Use Cases

• Modeling risk factors for postoperative nausea and vomiting based on patient age, surgery type, and nasogastric tube placement.
• Analyzing temporal trends in orthognathic surgery volume from 2014 to 2024.
• Evaluating the association between prophylactic measures like ondansetron administration and complication rates.

Strengths

• 667 patient cases spanning a 10-year period (2014-2024).
• Includes multivariable logistic regression results with odds ratios and confidence intervals for key variables.
• Explicitly states key descriptive statistics: mean age (27.2 years), gender distribution (69.3% female), and PONV incidence (7.9%).

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• Data is from a single department, which may limit generalizability.
• The dataset is very small (13.5 KB), indicating limited scope and likely a summary table rather than raw records.
