BACKGROUND: The summary of various studies done looking at size selection of the laryngeal mask airway (LMA) in adults is that, selection based on sex is appropriate, and that both sizes 4 or 5 are adequate for adult females. However, in our local population these sizes may be too large especially the size 5 for adult females. OBJECTIVE: To determine the optimal size of LMA in Malaysian female adults. METHOD: 135 ASA 1 or 2 adult female patients coming for elective surgery, requiring general anaesthesia suitable for LMA insertion were randomised into 3 groups to receive either a size 3, 4 or 5 LMA. Optimal size of the LMA was assessed based on 4 parameters, the number of attempts at placement, the oropharyngeal leak pressure (OLP), fibre optic score and the percentage of the vocal cords seen. RESULTS: The 3 groups were demographically similar. There was no difference in the 3 groups in terms of number of attempts of placement, OLP and fibre-optic score. The percentage of vocal cords seen with the size 3 LMA was significantly less than for the size 4 and size 5 (p = 0.009). For the size 5 LMA group in 10/45 patients, the size 5 LMA was too big making it incorrectly positioned after successful insertion and in another 3/45 patients it was difficult to pass the size 5 LMA past the open mouth during insertion. There were no such problems with the size 3 or 4 LMA groups. CONCLUSION: The optimal size of LMA for the female Malaysian adult is size 4.

Laryngeal mask airway (LMA) is an adjunctive airway device composed of a tube with a cuffed mask-like projection on the distal end, which is more practical than a face mask and less invasive than an endotracheal tube. It has the great economical advantage of being reusuable. Even though the LMA withstands a large number of sterilization cycles without undergoing damage, these sterilization cycles make the tear strength of the LMA lower. And it can be easily damaged during anesthesia or sterilization. We report a case of a fracture of the LMA during anesthesia probably caused by teeth as well as prolonged and repeated use.
