Visual analogue scale assessment of postoperative swelling. A study of clinical inflammatory variables subsequent to third-molar surgery.
Subsequent to removal of impacted lower third molars the interrelationship of four postoperative variables (swelling, pain, trismus, and dysphagia) was assessed. Patient assessment of postoperative swelling using a visual analogue scale (VAS) was easily accepted by a group (n = 40) of patients aged 17 to 46 years. A significantly positive correlation (r = 0.66, p less than 0.01) existed between metric extraoral swelling and VAS-assessed swelling; however, the latter may represent a more sensitive method when swelling is discrete. Both extraorally and VAS-assessed swelling showed no correlation with dysphagia and VAS-assessed pain. Trismus correlated moderately positively with pain and extraoral swelling (r = 0.38, p less than 0.05) and dysphagia (p less than 0.01). In the present study dysphagia showed no correlation with pain. This study shows that registration of postoperative swelling by means of a VAS may be a sensitive and accurate method with obvious practical advantages.
