The role of serial physical examinations in the management of angioedema involving the head and neck: A prospective observational study☆
2016
Abstract Objective To elucidate the progression of angioedema of the head and neck with routine management and to assess the utility of serial physical exams and fiberoptic laryngoscopy in its management. Methods This study was a prospective observational research. From 2013 to 2014, a prospective observational study was conducted at a tertiary referral center. Forty patient were approached, 7 refused, 33 (18–90 years old) were enrolled. Patients presented with angioedema involving the head and neck over a 12 month period were asked to participate in the study. Physical examination and fiberoptic laryngoscopy were performed at presentation and then repeated at least 1 h later. Results Thirty-three patients with head and neck angioedema from any cause were enrolled (mean age 58, range 23–89 years). The upper lip was the most commonly involved site (58%). On reevaluation, 82% of patients reported subjective improvement in symptoms. The association between subjective improvement and the physical exam, including fiberoptic laryngoscopy findings, was statistically significant ( P Conclusion In stable patients with angioedema of any head and neck subsite, self-reported symptoms are associated with clinical stability or improvement as assessed by physical signs and fiberoptic laryngoscopy. Patients' symptoms may be an appropriate surrogate to monitor clinical status without the need for routine serial physical examinations or fiberoptic laryngoscopy, though further study is needed.
