Publication Open Access Effects of orthognathic surgery on pharyngeal airway space: A literature review(2014-05) Nguyen, Minh Truong; Surakit Visuttiwattanakorn; สุรกิจ วิสุทธิวัฒนากร; Truong, Dung Manh; Natthamet Wongsirichat; ณัฐเมศร์ วงศ์สิริฉัตร; Surakit Visuttiwattanakorn; สุรกิจ วิสุทธิวัฒนากร; Mahidol University. Faculty of Dentistry. Department of Oral and Maxillofacial SurgeryPharyngeal airway changes after orthognathic surgery have been concerned because of the effects on breathing function of the patients. Moreover, sleep quality of patients can be improved or worsened by these changes. Obstructive sleep apnea is a... disorder characterized by episode of pharyngeal airway collapse. It may be better following a maxillomandibular advancement surgery or may be worsened or developed after mandibular setback surgery. The purpose of this study is to review the changesPublication Metadata only Prediction of pharyngeal airway changes in skeletal class III deformity patients after orthognathic surgery(2015-01-01) Minh Truong Nguyen; Surakit Visuttiwattanakorn; Natthamet Wongsirichat; Mahidol University; HANOI© 2015 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI. Background: Pharyngeal airway changes after orthognathic surgery in skeletal class III patients have been of concern because of the effects on breathing function. Objectives: The aim... of this study was to evaluate the pharyngeal airway changes in patients with skeletal class III deformity who underwent orthognathic surgery. Materials and methods: Thirty-two patients who underwent orthognathic surgery at Oral and Maxillofacial SurgeryItem Metadata only Volumetric Changes in the Pharyngeal Airways of Skeletal Class III Patients Following Various Orthognathic Surgeries: A Short-/Long-Term Follow-Up(2026-01-01) Soodtoetong U.; Kitisubkanchana J.; Srimaneekarn N.; Seifert L.B.; Vorakulpipat C.; Soodtoetong U.; Mahidol UniversityOrthognathic surgery corrects skeletal deformities affecting the pharyngeal airway. This study assessed immediate and long-term volumetric changes in the airway after surgery. In this observational study, upon orthognathic surgery, 52 class III... prediction model for % change in pharyngeal volume using ∆B (P<0.05). Orthognathic surgery, particularly isolated mandibular setback, narrows the pharyngeal airway. Monitoring postoperative airway changes is crucial, especially for obstructive sleep apneaItem Metadata only Performance enhancement of deep learning based solutions for pharyngeal airway space segmentation on MRI scans(2024-12-01) Leeraha C.; Kusakunniran W.; Yodrabum N.; Chaisrisawadisuk S.; Vathanophas V.; Siriapisith T.; Leeraha C.; Mahidol UniversityThe automatic segmentation of the pharyngeal airway space has many potential medical use, one of which is to help facilitate the creation of the Tubingen Palatal Plate. Therefore, it is of great importance to understand which methods are suitable..., while others were taken from the medical or pharyngeal airway space segmentation literature. Some models are convolutional neural networks, while others are transformer-based model or a mix of both convolutional and transformer-based model. These modelsItem Metadata only Automated Computed Tomography Segmentation of the Pharyngeal Airway and Palate to Accelerate Tübingen Palatal Plate Fabrication in Pierre Robin Sequence(2025-12-10) Yodrabum N.; Vongviriyangkoon T.; Apichonbancha S.; Kuskunniran W.; Leeraha C.; Siriapisith T.; Tantipanichkul K.o.; Vathanophas V.; Chaisrisawadisuk S.; Yodrabum N.; Mahidol Universityrequires serial intraoral impressions and repeated nasoendoscopy, which prolongs airway compromise. Computed tomography (CT) enables single-session virtual spur design, yet manual pharyngeal airway and hard palate segmentation is labor-intensive, delaying...Infants with Pierre Robin sequence frequently develop upper airway obstruction due to micrognathia and glossoptosis. The Tübingen palatal plate repositions the tongue base anteriorly to improve airway patency; however, conventional fabricationPublication Metadata only The Ramathibodi Nasal filter in a simulated human airway: Evaluated with laser smoke particles and a laser diode dust portable monitor(2001-12-01) Kunchitthape Tanpowpong; Chumroon Chiratthiti; Mahidol University; Thailand Ministry of Public HealthThe Ramathibodi nasal .filter was specially designed as a personal respiratory protective device. It was attached to a simulated human airway composed of a nasal and pharyngeal model, airway passage and lung model machine. The system was run in a... laser smoke particles environment. The laser smoke particles with suspended particulate matter size of less than 15, 10 and 2.5 microns (PM15, PM10 and PM2.5) were selected. The amount of each particle size in the simulated human airway with and withoutPublication Metadata only Choanal atresia(2009-05-01) Paraya Assanasen; Choakchai Metheetrairut; Mahidol UniversityChoanal atresia is caused by failure of resorption of the bucco-pharyngeal membrane during embryonic development. The atresia can be membranous or bony in nature, but is usually mixed in most cases. When the atresia is bilateral, newborns can have... severe airway distress and cyanosis is alleviated by crying. Bilateral choanal atresia is managed with an oropharyngeal airway. Flexible nasal endoscopy and computed tomography can confirm the diagnosis. Surgery is the definitive treatment with two mainPublication Metadata only Efficacy of the Ramathibodi nasal filter in a simulated human airway evaluated by a laser diode portable dust monitor under low laser smoke particle concentration(2002-02-01) Kunchitthape Tanpowpong; Chumroon Chiratthiti; Mahidol University; Thailand Ministry of Public HealthThe Ramathibodi nasal filter attached to a simulated human airway was proposed to filter laser smoke particles. The simulated human airway composed of nasal and pharyngeal model, airway passage and lung model machine which mimicked the human... to March 2000. The simulated human airway got an equal amount of laser smoke particles in a sealed plastic box for 1 min. The residual amount of laser smoke particles in a closed system of the simulated human airway was measured by a laser diode portablePublication Metadata only Overview of surgical therapies for obstructive sleep apnea: A concise review literature(2020-01-01) Lee Kian Khoo; Sutichai Norranitchaiyakul; Suphachai Suphangul; Natthamet Wongsirichat; Walailak University; Mahidol University; Vinayaka Mission's Research Foundation© 2020 Faculty of Medicine Siriraj Hospital, Mahidol University. The surgical therapy of Obstructive Sleep Apnea (OSA) requires addressing anatomical obstructions or collapse of the pharyngeal airway by skeletal and soft tissue surgeries. Numerous... surgical options have been documented for OSA therapy with varying success. OSA surgery is vital when patients refuse continuous positive airway pressure (CPAP). The aim of this article is to review surgeries for OSA and the effectiveness of each surgeryItem Metadata only Deglutition Assessment, Using Fiberoptic Endoscopic Evaluation of Swallowing in Patients underwent Frontolateral Laryngectomy(2023-09-01) Ongard S.; Keskool P.; Chotigavanich C.; Plasen N.; Metheetrairut C.; Mahidol Universityto be normal in 27 cases (75%), however, six cases or 16.7% had mild residue accumulation after food swallowing, whereas three cases (8.3%) had moderate symptoms of either minimal pharyngeal stasis plus unsafe airway or moderate pharyngeal residue accumulation
