Abstract

Background: Radiation sinusitis after radiotherapy for nasopharyngeal carcinoma occupies a large proportion and affects the subsequent therapeutic process as well as diagnosis, which can be improved by traditional Chinese medicine treatments.

Methods: Based on the relevant clinical randomized controlled trials (RCTs) from eight databases, a network meta-analysis (NMA) in a frequentist framework was constructed after study selection, data extraction, and quality evaluation of the included studies. The outcomes included total effect, the Lund Kennedy score of nasal endoscopy and the Lund Mackay score of sinus CT.

Results: For total effect, the order of probability for the effect is: external herbal medicine + herbal medicine orally > nasal saline + herbal medicine orally > herbal medicine orally > external herbal medicine > external herbal medicine + nasal saline > nasal saline + western medicine orally > none > nasal saline. For the Lund Kennedy score, the order of probability for the effect is: nasal saline + herbal medicine orally > herbal medicine orally > external herbal medicine > none > nasal saline. For Lund Mackay score, the order of probability for the effect is: herbal medicine orally > nasal saline + western medicine orally > nasal saline + herbal medicine orally > nasal saline > external herbal medicine.

Conclusions: Herbal medicine taken orally and through nasal cavities combined with nasal saline has a better clinical effect than a single intervention for total effect and Lund Kennedy score. As the classification of this research is relatively macro and the sample size is insufficient, further higher-quality studies are needed to verify the conclusion.
