Traditional Chinese medicine in chronic rhinosinusitis: Mechanisms and postoperative recovery

Abstract

Background

Chronic rhinosinusitis (CRS) is inflammation of the sinuses and nasal passages that lasts for >3 months. Its pathogenesis is complex, treatment is difficult, and it has multiple effects on patients. Although surgical treatment can effectively relieve the symptoms, the recurrence rate is high, and there are postoperative complications such as infection. At present, nasal spray hormone, antibiotics and other western drugs are used in clinical treatment, but there are drug dependence and toxic side effects. However, traditional Chinese medicine (TCM) has made remarkable progress in the treatment and promotion of postoperative recovery, guided by its unique TCM theory, and has little toxic and side effects, providing more treatment options for patients.

Purpose

The review aims to elucidate the mechanism of CRS from the aspects of traditional medicine and modern medicine, and evaluate the influence of TCM compound, components of TCM, TCM nasal irrigation, TCM fumigation and other auxiliary treatment methods on CRS, providing a new perspective for the application of TCM in CRS.

Methods

We conducted the literature retrieval with PubMed, Web of Science, Google Scholar and CNKI databases in a systematic manner (up to July 2024). The keywords included "sinusitis", "chronic rhinosinusitis", "nasal polyps", "herbal medicine", "medicinal plants", "traditional Chinese medicine", "oxidative stress", "pathogenic microbial", "anatomic structure" and so on. The obtained literatures were comprehensively sorted out. For image creation, Figdraw 2.0 was methodically employed.

Results

The pathogenesis of CRS involves various interaction mechanisms such as bacterial biofilm formation, oxidative stress injury and impaired ciliary mucosa clearance. It is worth noting that TCM exerts therapeutic effects by targeting the above-mentioned pathological processes. Clinical studies have confirmed that TCM comprehensive therapy can significantly improve sinus symptom score, accelerate postoperative mucosal epithelialization, and promote postoperative rehabilitation of CRS. We also discussed the toxic side effects and clinical applications of related drugs.

Conclusion

In TCM, CRS is classified under the diagnostic category of Bi Yuan. Its pathogenesis is attributed to exogenous invasion of the six climatic pathogens (Liu Yin: wind, cold, summer heat, dampness, dryness, and fire), spleen-stomach qi deficiency, internal damp-heat accumulation, and qi-blood stasis. Guided by TCM principles, therapeutic strategies are individualized through syndrome differentiation, which tailors interventions to the patient's unique clinical manifestations. Therapeutic modalities include oral herbal formulations (e.g., decoctions or granules), acupuncture, and acupoint application. These approaches aim to restore physiological balance by harmonizing yin and yang, resolving meridian obstructions, and enhancing lung qi circulation to alleviate nasal congestion and improve ventilation.
