Oropharyngeal airway obstruction after the accidental ingestion of arisaema amurense - Ryoo SM, Sohn CH, Oh BJ, Kim WY, Lim KS, Lee CC.

BACKGROUND: Arisaema amurense is widely known in Korean folklore as a poisonous plant, and its lethal toxicity has long been recognized. The toxicity of Arisaema amurense is due to its content of calcium oxalate, which causes painful oropharyngeal edema, h...

This study aimed to determine the correlations between the craniofacial morphology and pharyngeal airway volume in patients with complete bilateral cleft lip and palate (BCLP). DESIGN: Retrospective study. SETTING: Tertiary hospital. PARTICIPANTS: Twenty-seven patients with complete BCLP and 27 class I control patients, aged 10 to 14 years. MAIN OUTCOME MEASURE: The pharyngeal airway volume and craniofacial morphology were evaluated using cone-beam computed tomography. Measurements were compared between groups and any correlations were identified. RESULTS: A significantly smaller total pharyngeal a...

Mandibular setback surgery can change the position of the mandible which improves occlusion and facial profile. Surgical movement of the mandible affects the base of the tongue, hyoid bone, and associated tiss...

Abstract Conventional in vitro tests to assess the aerodynamic particle size distribution (APSD) from inhaler devices use simple right-angle inlets ("mouth-throats", MTs) to cascade impactors, and air is drawn through the system at a fixed flow for a fixed time. Since this arrangement differs substantially from both human oropharyngeal airway anatomy and the patterns of air flow when patients use inhalers, the ability of in vitro tests to predict in vivo deposition of pharmaceutical aerosols has been limited. MTs that mimic the human anatomy, coupled with simulated breathing patterns, have yielded estima...

CONCLUSION: The upper airway values did not show any significant discrepancies between the two groups during the observation period. CLINICAL SIGNIFICANCE: Functional devices were effective in solving class II relationships, but there is no evidence of successful breathing disorders prevention by using mandibular activators, probably due to the stability of airway tissues reached in pubertal age in both groups.

ConclusionThe present study is a basic study demonstrating how different techniques of ESP affect the position of the soft palate. The PP –SPC attachment can be transected in the patients with anterior–posterior palatal and lateral wall collapse to pull the soft palate anteriorly in addition to prevent the lateral wall collapse. The PP–SPC attachment can be preserved in the patients with only lateral wall collapse. Nevertheless, the clinical consequences of these static changes need to be evaluated in clinical studies.

Authors: Matsui R, Wong M, Waters B Abstract Transoral application of a nasopharyngeal airway (NPA) is a novel technique for difficult airway management. Clinically, it is an effective alternative for use in nonintubated dental cases under total intravenous anesthesia. This technique can help improve oxygenation and ventilation in clinical situations in which the conventional use of NPAs is ineffective, such as in patients who have findings of obesity; mandibular retrognathia or hypoplasia; maxillary hypoplasia; macroglossia; nasal obstruction secondary to hypertrophic tonsillar, adenoid, and/or lymphoid tissues or...

In the early twentieth century, many physician-anesthetists packed example(s) of an oropharyngeal airway in their toolboxes. Although metal varieties invented by Connell or Waters werestatus quo, these forced physicians to tolerate a patent but potentially traumatized patient airway in the form of bruised lips and chipped teeth. Enter Arthur E. Guedel, M.D. (1883 to 1956,left), with his “nontraumatic pharyngeal airway,” publicized in 1933 from his adopted hometown of Beverly Hills, California. Constructing his semicircular oropharyngeal airway of rubber that could flex to any individual’s anatomy, Dr. Gue...

AbstractObjectiveDistraction osteogenesis maxillary expansion (DOME) is a reliable method to expand the nasal floor and hard palatal vault in adults with obstructive sleep apnea (OSA). DOME results in a reduction in the apnea-hypopnea index (AHI) and subjective report of improved nasal breathing. Using rhinomanometry augmented computational fluid dynamic (CFD) modeling, we propose a mechanism of how DOME reduces upper airway pharyngeal collapse in adults with OSA.Material and methodA retrospective cohort with 20 subjects and mean age of 29.6 ± 8 years who completed DOME at Stanford University from September 2014 to ...

Authors: Yu X, Wang J, Hou S, Zeng R Abstract Temporomandibular joint (TMJ) ankylosis in pediatric patients is rare and may cause severe micrognathia and obstructive sleep apnea syndrome. The present study reports on the treatment and 4-year follow-up of a pediatric patient with early-onset bilateral TMJ ankylosis and severe secondary micrognathia, as well as obstructive sleep apnea syndrome. A typical 'bird face' appearance was noted with severe mandible retrognathism and a significant convex facial profile. The treatment of this patient involved TMJ ankylosis release with condylectomy and simultaneous bilateral m...

Conclusions: The prototype VHC may provide a potential option for patients previously unwilling to carry more conventional VHCs with them, in order to give delivery assurance of their reliever medication.
