Comparative study between biodegradable nasopore (BNP) and Merocel hemox 10 cm after septo-turbinoplasty procedure

The purpose of our study was to compare Merocel (Merocel Hemox 10 cm) and BNP (biodegradable nasopore) during a septoturbinoplasty procedure in terms of efficiency and patient comfort.

We carried out a retrospective review of 72 patients who had undergone septoturbinoplasty between January 2015 and January 2016. Each group, packed with BNP or Merocel Hemox 10 cm was composed of 36 patients. A standard visual analogue scale ranging from zero (no symptoms) to 10 (the most severe symptoms) was used to assess subjective symptoms. To compare the usefulness of materials we evaluated the postoperative bleeding, infection and adhesion after the removal of packing with and endoscopic examination using a 5-point scale (zero, absent; 1, mild; 2, moderate; 3, severe; and 4, very severe). Secretions and crusts were evaluated 1 week and 4 weeks after surgery in both groups using a 5-point scale (zero, absent; 1, mild; 2, moderate; 3, severe; and 4, very severe).

A total of 72 patients were enrolled in the study, 45 women and 27 men; age range 15-78 with a mean age of 47 years. In the group A (Merocel group), 21 cases showed grade 1 bleeding (58%), 11 cases grade 2 (30%) and 4 patients grade 0 (11.1%). In the group B (BNP group), 29 cases showed grade 0 bleeding (80.56%) and 7 cases showed grade 1 bleeding (19.44%). There was a statistical significant difference between the Merocel group and the BNP group in terms of bleeding after removal of packing material (p < 0.05). In the group A, 16 patients developed mild adhesion (44%), 8 patients moderate adhesion (22.2%), 3 patients severe adhesion (8.33%) and 1 patient very severe adhesion (2.77%). BNP nasal packing didn't cause any adhesion in 25 patients (69.4%), 11 patients developed mild adhesion (30.5%). So there was a statistical significant difference between group A and group B regarding the adhesion (p < 0.05). There was a statistically significance reduction of nasal secretions and crusts at a week after surgery in the BNP group vs. Merocel group. The difference is not statistically significant 4 weeks after surgery. About the severity of symptoms related to nasal packing, we found a statistically significant difference (p < 0.05) between Merocel and BNP group regarding the pain during packing removal, the general satisfaction and the pressure.

Biodegradable nasopore reduced pain and patient discomfort during packing removal and causes less bleeding compared to Merocel hemox 10 cm. This type of material can be used after septoturbinolplasty.
