“…Katz et al [ 13 ] used PSG results to show that the duration of apnea–hypopnea > 2 breathing cycles, AHI ≥ 5 times/h, and LSR < 92% were the diagnostic criteria for children with OSA. In terms of treatment, surgical removal of its anatomical stenosis is an important principle for the treatment of OSA [ 14 ].…”

Background Current research about hemifacial microsomia (HFM) patients after distraction osteogenesis (DO) most emphasize the morphologic changes. This case report shows the outcome of DO on the upper airway of a HFM patient with obstructive sleep apnea (OSA) based on the use of computational fluid dynamics (CFD). Case presentation An 11-year-old boy was diagnosed as HFM with OSA, and underwent unilateral DO. Polysomnography and CT scans were performed before and 6 months after treatment. After DO, lowest blood oxygen saturation increased from 81% to 95% and apnea and hypopnea index decreased from 6.4 events/hour to 1.2 events/hour. The oropharynx and nasopharynx were obviously expanded. We observed apparently increased average pressure, decreased average velocity and pressure drop in all cross-sections, and largely decreased airflow resistance and maximum velocity entirely in the airway. Conclusions The results suggest that DO might be effective for the treatment of OSA by expanding the upper airway and reducing the resistance of inspiration.

“…At present, it is considered that the stenosis and dysfunction of the upper airway are the most important causes of OSA [15]. In terms of treatment, OSA is a sleep disorder characterized by obstruction of the upper airway, and surgical removal of its anatomical stenosis is an important principle for the treatment of OSA [16]. Among the surgical treatments, tracheotomy is the earliest, but it is only used in palliative or emergency situations.…”

“…Therefore, the knowledge and understanding of the flow properties of upper airway are practically important for medical practitioners and surgeons to accurately locate the obstruction in OSA patients [14,15] . Surgical correction of OSA syndrome is one of the alternative methods to tackle the obstruction of the upper airway [16] . The understanding of a three-dimensional (3D) airway anatomy is crucial for the surgical correction of OSA because it involves a number of parameters such as internal airflow velocity, wall shear stress, and pressure drop [17] .…”

Background and objective: Human upper airway (HUA) has been widely investigated by many researchers covering various aspects, such as the effects of geometrical parameters on the pressure, velocity and airflow characteristics. Clinically significant obstruction can develop anywhere throughout the upper airway, leading to asphyxia and death; this is where recognition and treatment are essential and lifesaving. The availability of advanced computer, either hardware or software, and rapid development in numerical method have encouraged researchers to simulate the airflow characteristics and properties of HUA by using various patient conditions at different ranges of geometry and operating conditions. Computational fluid dynamics (CFD) has emerged as an efficient alternative tool to understand the airflow of HUA and in preparing patients to undergo surgery. The main objective of this article is to review the literature that deals with the CFD approach and modeling in analyzing HUA.Methods: This review article discusses the experimental and computational methods in the study of HUA. The discussion includes computational fluid dynamics approach and steps involved in the modeling used to investigate the flow characteristics of HUA. From inception to May 2020, databases of PubMed, Embase, Scopus, the Cochrane Library, BioMed Central, and Web of Science have been utilized to conduct a thorough investigation of the literature. There had been no language restrictions in publication and study design of the database searches. A total of 117 articles relevant to the topic under investigation were thoroughly and critically reviewed to give a clear information about the subject. The article summarizes the review in the form of method of studying the HUA, CFD approach in HUA, and the application of CFD for predicting HUA obstacle, including the type of CFD commercial software are used in this research area.
