Area of Science:

  • Oral and Maxillofacial Surgery
  • Surgical Outcomes Research
  • Predictive Modeling

Background:

  • Individualized prediction of postoperative symptom severity is crucial for effective intervention planning following mandibular third molar (M3M) removal.
  • Current methods may lack precision in anticipating patient-specific recovery trajectories.

Purpose of the Study:

  • To develop and validate a predictive nomogram for estimating postoperative symptom severity after M3M extraction.
  • To provide a tool for personalized risk assessment and intervention selection.

Main Methods:

  • A prospective cohort study involving 321 patients undergoing M3M removal.
  • Data included demographic, anatomic, radiographic, and operative variables.
  • A nomogram was developed using multivariable logistic regression and validated on an independent dataset.

Main Results:

  • Gender, age, smoking status, operation time, Pell-Gregory ramus classification, and preoperative symptoms were identified as significant predictors.
  • The nomogram demonstrated adequate discrimination (AUC=0.69) and good calibration in the validation set.
  • The model achieved an accuracy of 65.1% in the testing dataset.

Conclusions:

  • An effective nomogram has been developed for the individualized prediction of postoperative symptom severity after M3M removal.
  • This tool has potential applications in guiding clinical decision-making and tailoring patient management.
