[Clinical analysis for 56 cases of postnasal drip syndrome]

This paper is aimed to analyse the pathogeny of postnasal drip syndrome including of cough, postnasal drip and pharyngeal foreign body sensation. And explore to the appropriate diagnosis and treatment strategy.

The author took 56 cases of PNDs as examples. The 56 cases were switched to FESS. The author frequently visit the 56 patients after treatment for 6 months and did SNOT-20 (the sino-nasal outcome test-20) scale assessment of the symptom improvement in patients before and after the situation. The author also compared the symptom score differences between postnasal drip and cough and explored the disease causes and assess the postoperative recovery status.

In patients with 56 cases PNDs, chronic rhinosinusitis in 22 patients (39.3%), nasal polyps in 11 patients (19.6%), deviation of nasal septum partial in 5 patients (8.9%), the adenoids in 10 patients (17.9%), the fungal sinusitis in 5 patients (8.9%), the maxillary sinus hemorrhagic polyp in 2 cases (3.6%), the nasal-sinal neoplasm in 1 cases (1.8%). SNOT-20 rating scale result showed:r = 0.674 (P < 0.01), r = 0.062 4 (P < 0.01), postnasal drip and cough symptoms score with certain relevance. Before and after the operation of score comparison about the "postnasal drip" symptoms, scoring significant difference (P < 0.01), namely the surgical treatment had distinct effect. And "cough" symptoms score before and after operation had a significant difference (P < 0.01).

"postnasal drip" and "cough" symptoms occur with some relevance. After the FESS the two symptoms are improved significantly.
