OBJECTIVE: The objective of this study was to evaluate efficacy and safety of a Hypertonic Seawater Solution (2.3% NaCl) containing brown and blue-green Algae (HSS-A) in comparison to Isotonic Saline Solution (ISS) regarding the improvement of nasal breathing in patients that have undergone surgical correction of a deviated nasal septum and radiofrequency turbinate volume reduction.

PATIENTS AND METHODS: A total of 101 individuals were enrolled in the study (HSS-A: 57; ISS: 44). Nasal breathing was evaluated using a Peak Nasal Inspiratory Flow (PNIF) measurement device at four timepoints: prior to surgical intervention (up to 30 days pre-surgery) and at the 2nd, 10th and 20th postoperative days. On the 20th postoperative day, patients also answered a Nasal Surgical Questionnaire (NSQ) evaluating breathing ability and overall satisfaction from the use of both nasal sprays.

RESULTS: No significant differences were observed in PNIF measurements between groups at different points. On the 20th postoperative day, NSQ analysis showed that ISS-treated patients had more frequently moderate nasal bleeding compared to the HSS-A group (85.7% vs. 14.3%, p=0.038). No other statistically significant differences were observed between groups. When NSQ parameters were evaluated in a binary mode, a trend for reduced crusting scores was seen in the HSS-A group (15.9% vs. 35.5% in ISS, p=0.053). No safety concerns were reported throughout the study.

CONCLUSIONS: In patients that have undergone surgical correction of a deviated nasal septum and radiofrequency turbinate volume reduction, PNIF values did not differ significantly in patients receiving HSS-A and ISS solutions. Nasal bleeding was more frequent in ISS patients versus HSS-A. Overall, both solutions provided symptomatic relief and use satisfaction in the absence of side effects.
