Application of nasal flexible laryngeal mask airway in anesthesia for oral surgery

Flexible laryngeal mask airway management for dental treatment cases associated with difficult intubation

“…In our experience, FLMA could be used to obtain an airway during general anesthesia. The FLMA passed beyond the tongue, forming a laryngeal seal, eliminating the risk of causing upper airway obstruction [ 4 5 6 ]. The cuff portion of the FLMA is similar to that of the classic version of the LMA but the FLMA has a long and non-rigid flexometallic tube [ 7 8 ].…”

“…Devices such as the laryngeal mask airway (LMA) and fiberoptic scope are effective in establishing an airway during a difficult intubation [ 2 3 4 ], and the LMA can be used for maxillofacial surgery [ 5 6 ]. Of note, the flexible LMATM (FLMA; The LMA Company, San Diego CA, USA) has a long cuff portion and non-rigid flexometallic tube [ 4 ], which might decrease the risk of developing an airway disorder. Here, we present our experience using FLMA airway management for two dental treatment cases involving difficulty with intubation.…”

The laryngeal mask airway and otorhinolaryngology head and neck surgery

“…Although pushing the tube of an LMA with a finger into the oral vestibule and the retrodental space opposite to the treatment site may be a solution to this problem, dislodgment of the mask or obstruction of the tube may occur. Attempts have been made to develop an LMA inserted transnasally, which may further improve oropharyngeal procedures 25–27…”

A detachable, reinforced laryngeal mask airway for transnasal application in oral surgery

“…Although pushing the tube of RLMA with a finger into the oral vestibule and the retrodental space opposite to the treatment site may be a solution to this problem, dislodgment of the mask part or obstruction of the tube part may occur [5]. In 2007, Arisaka et al [7] described a modification of the method. In 1997, Marchionni et al [6] reported a method for inserting an RLMA tube retrogradely through the nostril using via a Foley catheter.…”
