Effect of intranasal stents (AlaxoLito, AlaxoLito Plus and AlaxoLito Xtreme) on the nasal airway: A case report

Figure 1 AlaxoLito (A) and AlaxoLito Plus (C-E) Nasal Stents with insertion tube. Insertion method: B and C: The stent is placed inside the insertion tube, which allows for easy insertion; D: Once the insertion tube is placed into the nasopharynx; E: It is withdrawn, allowing the stent to open inside the nasal cavity.

Figure 2 Rhinomanometric data without and with stents.

Figure 3 Comparison of coronal magnetic resonance imaging of nasal passages prior to and 1 year post regular stent use. A: Magnetic resonance imaging (MRI) from December 2015 prior to regular use of stents, without stents; B and C: MRI from June 2017 one year post regular use of AlaxoLito Plus stent (B: without stents in situ; C: with AlaxoLito Plus in situ).

Figure 4 Coronal magnetic resonance imaging showing measurements of middle nasal passage without stents (A-C) and with stents in situ (D-F). A and D: Magnetic resonance imaging (MRI) from December 2015 prior to regular use of stents; B and E: MRI from June 2017 one year post regular use of AlaxoLito Plus; C and F: MRI from September 2018, 3.5 mo post regular use of AlaxoLito Xtreme.
