Office based inferior turbinate coblation treatment: a randomized controlled trial on effectiveness and tolerability of medicinal honey [PDF]
Rhinology Online, 2022 Background: When conservative treatment for nasal obstruction fails, surgery is often applied. Inferior Turbinate Hypertrophy (ITH) is a common cause of nasal obstruction, which can be treated by means of radiofrequency coblation.

The effect of nasal surgery on apnea-hypopnea index [PDF]
Reviews in Clinical Medicine, 2014 One of the factors, which is involved in obstructive sleep apnea, is anatomic or inflammatory pathologies of nasal airway obstruction. Thus, it is logical to observe improvement of polysomnographic parameters of sleep-disordered breathing after nasal ...

Pressure distribution and flow dynamics in a nasal airway using a scale resolving simulation [PDF]
Physics of Fluids 33, 011907 (2021);, 2021 Airflow through the nasal cavity exhibits a wide variety of fluid dynamicsbehaviour due to the intricacy of the nasal geometry. The flow is naturallyunsteady and perhaps turbulent, despite CFD in the literature that assumesa steady laminar flow. Time-dependent simulations can be used to generatedetailed data with the potential to uncover new flow ...
