Aerodynamic characteristics in upper airways among orthodontic patients and its association with adenoid nasopharyngeal ratios in lateral cephalograms
Feng, Xin; Chen, Yicheng; Cai, Weihua; Lie, Stein Atle; Hellén-Halme, Kristina; Shi, Xie-Qi (Journal article; Peer reviewed, 2021)Background Adenoid hypertrophy among orthodontic patients may be detected in lateral cephalograms. The study investigates the aerodynamic characteristics within the upper airway (UA) by means of computational fluid dynamics ... -
Cell therapy induced regeneration of severely atrophied mandibular bone in a clinical trial
Gjerde, Cecilie Gudveig; Mustafa, Kamal Babikeir Eln; Hellem, Sølve; Rojewski, Markus; Gjengedal, Harald; Yassin, Mohammed Ahmed Alamin Yousif; Feng, Xin; Skaale, Siren G; Berge, Trond Inge; Rosén, Annika; Shi, Xieqi; Ahmed, Aymen B; Gjertsen, Bjørn Tore; Schrezenmeier, Hubert; Layrolle, Pierre (Journal article; Peer reviewed, 2018)Background Autologous grafting, despite some disadvantages, is still considered the gold standard for reconstruction of maxillofacial bone defects. The aim of this study was to evaluate bone regeneration using bone ... -
Computational fluid–structure interaction analysis of flapping uvula on aerodynamics and pharyngeal vibration in a pediatric airway
Chen, Yicheng; Feng, Xin; Shi, Xie-Qi; Cai, Weihua; Li, Biao; Zhao, Yijun (Journal article; Peer reviewed, 2023)The uvula flapping is one of the most distinctive features of snoring and is critical in affecting airway aerodynamics and vibrations. This study aimed to elucidate the mechanism of pharyngeal vibration and pressure ... -
The effect of rapid maxillary expansion on the upper airway’s aerodynamic characteristics
Feng, Xin; Chen, Yicheng; Hellén-Halme, Kristina; Cai, Weihua; Shi, Xie-Qi (Journal article; Peer reviewed, 2021)Background The effect of rapid maxillary expansion (RME) on the upper airway (UA) has been studied earlier but without a consistent conclusion. This study aims to evaluate the outcome of RME on the UA function in terms ... -
Image-based analyses of morphology and function in the upper airway of orthodontic patients
Feng, Xin (Doctoral thesis, 2021-06-11)Adenoid hypertrophy (AH) is one of the most common causes of nasal obstruction in children and adolescents. This may lead to breathing-related symptoms such as mouth breathing, snoring, asthma, speech problems, and obstructive ...
