OBJECTIVES: Pneumatic compression garment therapy (PCGT) has been established as treatment for postradiotherapy lymphedema, and its use in head and neck patients is becoming more common. Although effects on interstitial edema of the cervical soft tissues have been studied, effects on internal laryngopharyngeal edema, as well as associated symptoms of dysphagia and dysphonia, have yet to be published.
METHODS: We surveyed 7 patients treated with radiation for head and neck cancer (HNC) who had also been prescribed PCGT for cervical lymphedema. Patients were asked about subjective experience with the device, and also administered the Eating Assessment Tool-10 (EAT-10) and Voice Handicap Index-10 (VHI-10) surveys regarding their symptoms after using PCGT. Laryngoscopy videos from these same periods were also reviewed and scored using a validated tool for assessing laryngopharyngeal edema.
RESULTS: 85% of patients reported at least some improvement in dysphagia and dysphonia following PCGT. Average EAT-10 score after PCGT was 11.4 and average VHI-10 score after PCGT was 8.7. These compare more favorably to historical scores for the same questionnaires in similar patient populations. Laryngeal edema scores on endoscopic examination were not significantly different after at least 3 months of therapy (pre: 20.15, post: 20.21, P = .975); however, the utility of this result is limited by a low inter-rater reliability (Krippendorff α = .513).
CONCLUSIONS: While we are unable to show any difference in objective assessment of laryngopharyngeal edema on endoscopic examination in this small pilot study, patients report substantial subjective improvement in postradiotherapy dysphagia and dysphonia following cervical PCGT that warrants more formal investigation.
