Registration Number
NCT02559284
Lead Sponsor
Laboratoire de la Mer
Brief Summary

The main objective of this study is to compare the effects of RESPIMER® NetiFlow® solution and device versus saline solution (0.9% NaCl), the standard treatment, used with RESPIMER® NetiFlow® device, both used postoperative care, in the context of ethmoid sinus surgery, at 14 days post-surgery.

Detailed Description

This is a comparative study between two postoperative treatments following ethmoid sinus surgery. The purpose of this study is to compare the effect of RESPIMER® NetiFlow® solution on nasal tissue repair versus saline solution (0.9% NaCl), the standard treatment.

The type of surgery selected for this study is total endoscopic ethmoidectomy. This is a frequently used standard surgery that requires nasal cleansing for an average of 28 days. This process allows the regeneration of the nasal epithelial lining of the wound (areas of exposed bone), as well as the healing of swelling and scarring due to the surgery.

The follow up last 28 days with 4 visits (D7, D14, D21 and D28).

RESPIMER® NetiFlow® : device of class I, with CE mark, in the indication of sinus postoperative care.

A - ExperimentalA postoperative care after ethmoid sinus surgeryTreatment Arm: 100 patients using Respimer® NetiFlow® solution as standard treatment for healing of nasal surgery wounds following an endoscopic ethmoidectomy as a postoperative care after ethmoid sinus surgery
B - ComparatorA postoperative care after ethmoid sinus surgeryControl Arm: 100 patients using saline solution (0.9% NaCl) as standard treatment for healing of nasal surgery wounds following an endoscopic ethmoidectomy as a postoperative care after ethmoid sinus surgery
Primary Outcome Measures
NameTimeMethod
Superior healing of nasal mucosa repair 14 days following endoscopic sinus surgery, between the RESPIMER® NetiFlow® solution and the saline solution armsD14 meaning 14 days (plus or minus 3 days) after surgery

Based on a ≥8 points difference in the total RHINO QoL score between the two groups.

Secondary Outcome Measures
NameTimeMethod
Efficacy in optimizing airway clearance and restoring respiratory health, as well as overall quality of lifePre-inclusion, D7, D14, D21 and D28

Compare the efficacy of RESPIMER® NetiFlow® versus saline solutions in optimizing airway clearance and restoring respiratory health, as well as overall quality of life using:

* RHINO QoL scores (a self-report of nasal congestion, facial pain, anterior and posterior rhinorrhea).

* NOSE nasal obstruction scores.

Additional details on duration of nasal washesD7, D14, D21 and D28 after surgery

Provide additional details on the duration of nasal washes according to the approved indication (patient record).

Satisfaction, convenience, ease of administration and ease of cleaning of the RESPIMER® NetiFlow® deviceD7, D14, D21 and D28 after surgery

VAS numerical values assessing the RESPIMER® NetiFlow® device in terms of satisfaction, convenience, ease of administration and ease of cleaning (patient's Case report Form).

Assess and compare the tolerabilityPre-inclusion, D7, D14, D21 and D28

Assess and compare the tolerability of RESPIMER® NetiFlow® versus saline solutions using a Visual Analog Scale (VAS) (burning sensation in the nose, alterations in taste and smell and epistaxis) (patient record).

Assess functionality of nasal liningD-1, D14, and D21

Assess functionality of nasal lining by evaluating mucociliary clearance by rhinoscintigraphy for all patients in the 2 Bordeaux centers' (Bordeaux University Hospital and Saint-Augustin Private Hospital):

* D-1 only for center's Bordeaux, 10 patients in each group (20 patients in total)

* D14 and D21 for all Bordeaux patients', estimated at 50 patients (15 in each group and in addition the same 10 patients of the D-1 visit, in each group).

Assess and compare the crustingPre-inclusion, D7, D14, D21 and D28

Assess and compare the crusting with :

* The number of patients with (whether or not obstruction exists) and without crusting.

* How many days it takes for the crusting to disappear and/or the difference in the total number of care days

Satisfaction and perceived efficacy of the nasal solutionD7, D14, D21 and D28 after surgery

VAS numerical values assessing the level of patient satisfaction and perceived efficacy in regard to the nasal solution that was used by each group (patient's Case report Form).

Efficacy in improving the trophicity of the nasal mucosa within the operated areaD14, D21 and D28

Assess the efficacy of RESPIMER® NetiFlow® versus saline solutions in improving the trophicity of the nasal mucosa within the operated area, using a Lund-Kennedy endoscopic score (20 points).
