INTRODUCTION
Video laryngeal masks have become alternatives to classical supraglottic airway devices in recent years. This review provides information on the background of these new medical devices, the most popular and widely used video laryngeal masks, their advantages, disadvantages and their main applications in airway management.
AREAS COVERED
In this review, the physical differences between video laryngeal masks and second-generation laryngeal mask airways, and their properties in specific clinical settings are discussed.
EXPERT COMMENTARY
To limit airway-related morbidity, an optimal position of supraglottic airway devices must be the primary goal. Extensive research has shown that blindly inserted laryngeal mask can be malpositioned in 50% to 80% of the cases. Therefore, blind insertion should be the exception rather than the rule unlike current practice. Video laryngeal mask airways have clear advantages in routine use and in difficult airway management since they allow a vision-guided technique. Henceforth, the properties perceived in clinical practice must be endorsed with quality clinical evidence.

The first device was supraglottic laryngeal mask. These tools help us to handle a normal and difficult airway, other than direct laryngoscopy. Supraglottic devices positioned above the vocal cords are used to ventilate patients. Address and resolve the disadvantages of the endotracheal ventilation. There are different types of laryngeal mask: Classical, Proseal, Flexible, Fastrach, Disposable: Supreme; i-gel.

Review
The laryngeal mask, provides a totally patent airway when positioned in the hypopharynx with remarkable patient tolerance, even at very light planes of sedation. The major advantages of the laryngeal mask are its ease of insertion, the absence of contact with the vocal cards, and the fact that it frees the hands of the anesthesiologist. Contraindications to its use result from its failure to seal the airway against regurgitation of gastric content. Laryngeal masks can be used easily instead of facial masks during anesthesia with spontaneous ventilation and, with experience, can be used for longer procedures using controlled ventilation. Suspected difficult intubation and establishment of a patent airway in emergency conditions are good indications for the use of this device. The laryngeal mask does not replace endotracheal intubation. It can, however, permit better management of the airway while waiting for personnel trained in endotracheal intubation. The nature of the pulmonary pathology seen in intensive care patients limits use of the laryngeal mask during intensive care. In the operating room few complications have been described, and postoperative discomfort is minimal. The laryngeal mask is a device positioned in the hypopharynx which allows separation of the digestive tract from the airway, without violation of either the larynx or the upper oesophageal sphincter. An endotracheal tube, because of its positioning, hinders normal glottic movement and narrows the airway.(ABSTRACT TRUNCATED AT 250 WORDS)

Review
Introduction of the laryngeal mask airway (LMA) has been a revolutionary development in airway management over the last decades. It was first used clinically in 1981 by A. Brain and has been widely used in Germany since 1990. Originally intended as a substitute for conventional mask respiration for short periods of general anaesthesia, the laryngeal mask is in the meantime used in many areas as an alternative to elective endotracheal intubation as well as an option for controlling difficult airways. This contribution provides an overview of the basics as well as practical aspects of LMA use, and discusses the possibilities and limitations of the laryngeal mask in daily practice.

Randomized Controlled Trial
This study aimed to compare the clinical effects of the Medis flexible laryngeal mask airway (FLMA) with those of the Ambu AuraFlex FLMA in pediatric ophthalmic surgery. A total of 80 patients, aged 1 to 5 years, in American Society of Anesthesiologists I-II, weighing ≥10 kg, and without any existing airway difficulties, were enrolled in this study. The patients were randomly divided into Group M (Medis FLMA) and Group A (Ambu AuraFlex FLMA). The time of insertion, number of attempts, finger assistance required, manipulation, oropharyngeal leak pressure (OLP), fiberoptic grade of view, and complications such as bloodstaining, hoarseness, and sore throat were recorded. Group M showed a significantly higher OLP than did Group A (P = .002); however, Group M required more finger assistance than did Group A (P = .009). There were no statistically significant differences between the 2 groups in terms of insertion time, number of attempts, manipulation, fiberoptic view grade, or complications. Both the Medis and Ambu AuraFlex FLMA can provide smooth ventilation during pediatric ophthalmic surgeries. The Medis FLMA showed a higher OLP than did the Ambu AuraFlex FLMA but required more finger assistance during insertion.
