Usefulness of endonasal mucoplasty in the surgical treatment of chronic rhinosinusitis with nasal polyps. Prospective study.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a disease with great impact on health. The surgical option using endoscopic sinus surgery is the therapeutic alternative when control of the disease is not achieved with medical treatment. Extensive endoscopic approaches are being postulated as a possible best surgical treatment option in certain phenotypes of CRSwNP. Endonasal mucoplasty associated with these approaches has been shown to be a complementary technique that improves both healing and mucosal edema in patients with CRSwNP in the short term. The aim of our study was to analyse the results of endonasal mucoplasty associated with a complete ethmoid-sphenoidotomy plus grade III frontal sinusotomy in the treatment of CRSwNP in the medium term. For this purpose, a prospective case-control study (10/10) was carried out on patients with CRSwNP. In the case group, endonasal mucoplasty in the left nostril was associated with surgery, and the control group was not. The assessment of quality of life at one year after surgery, as measured by the mean difference in SNOT-22 (mean [SD]), was significantly better in the case group than in the control group (45.9 [19.6]-26.6 [16.05] P=0.027). The endoscopic improvement in healing and mucosal edema, measured by the Modified Lund-Kennedy scale, showed relevant improvements, when comparing both nostrils, but without reaching significance (P=0.29). Endonasal mucoplasty promotes short-term healing, improving the quality of life in the medium term (one year) of patients treated with extensive endoscopic mucosal resections.
