swelling, pain
Following surgery, the patients received a questionnaire to complete, in
order to determine their level of pain and discomfort. The questionnaire
consisted of six items, five of which used a Likert scale with a four-point
response range, and one with a three-point range. Participants were
questioned about their subjective experiences with discomfort while eating,
pain, and their perception of swelling on the surgical side at two different
time points, T1 and T2, where T1 was 24 h following the surgical procedure
and T2 was three days later.
