BACKGROUND The purpose of the study is to compare the effects on the pharyngeal airway space of skeletal anchored face mask with those of tooth-borne facemask. METHODS We used two types of facemask for maxillary protraction, the tooth-borne facemask (TBFM) and the skeletal anchored facemask (SAFM), and evaluated the effects of each facemask on the pharyngeal airway. Twenty-eight patients (mea...

BACKGROUND The facemask is used to treat early class III malocclusion, in combination with expansion therapy. There is a great deal of controversy in literature regarding the effectiveness of protraction facemask treatment as studies report results anywhere from considerable changes to lack of any maxillary improvement. This controversy may be due to the fact that the process of placing the ort...

Introduction: This case report describes the use of a Supraglottic airway device, air-QTM as a substitute for facemask ventilation in the induction of anesthesia in a neonate with oral tumors. Case presentation: A 6-day-old female with large oral tumors extruding from her mouth was scheduled to undergo surgery, but difficulty using the facemask ventilation was predicted. Therefore, we planned a...

Flavoring a facemask with a lip balm for inhalational induction in children is a common practice. However, most anesthesia providers are unaware of potential complications and the management of allergic reactions caused by lip balm. We describe the occurrence of allergic reaction to lip balm-flavored facemask in a child who underwent an inhalational anesthetic induction. The facial rash resolve...

BACKGROUND Respiratory protection efficiency of facemasks is critically important in the battle against communicable respiratory infections such as influenza and severe acute respiratory syndrome (SARS). We studied the spatial distributions of simulated virus-laden respiratory droplets when human subjects wore facemasks and were exposed to regulatory viral droplets by conducting in vivo experim...

PURPOSE We sought to compare the ability of novice operators to provide artificial ventilation using a standard facemask and a new ergonomically designed facemask. Whether or not proper technique was used was also assessed. METHODS Thirty-two allied-health students used both masks in random crossover fashion to ventilate an airway trainer. Breaths were delivered by a mechanical ventilator and...

OBJECTIVES The purpose of this study was to determine effects of different airway devices and tidal volumes on lung ventilation and gastric inflation in an unprotected airway. METHODS Thirty one non-anaesthesia house officers volunteered for the study, and ventilated a bench model simulating an unintubated respiratory arrest patient with bag-valve-facemask, laryngeal mask airway, and combitub...

who required only oxygen for a brief period, and the same facemask had been used. None of them had developed any signs ofinfection. On the initial screening S pneumoniae type 6 was isolated from the T piece connector of the face mask (figure). Repeat examination ofthe same facemask and connector seven days later yielded S pneumoniae type 6 from the thread of the T piece, which was contaminated ...
