insertions were conducted by those with experience of less than 15 previous insertions. Methods: Before induction, we measured the thyromental and sternomental distance. Devices may have deleterious effect on cervical mucosa or vasculature depending on their cuff volume and pressure.Ä«ackgroud: The purpose of this study was to assess the effect of inflating a laryngeal mask airway (PLMATM) cuff, prior to insertion, on the degree of difficulty of inserting a by the inexperienced, and the incidence of postoperative sore throat. Mild short-lasting adverse effects of the devices have significantly higher incidence than serious complications and involve postoperative sore throat, dysphagia, pain on swallowing, or hoarseness. Other serious, but extremely rare, complications include pharyngeal rupture, pneumomediastinum, mediastinitis, or arytenoid dislocation. The incidence of gastric content aspiration associated with the devices is estimated to be as low as 0.02% with perioperative regurgitation being significantly higher but underreported.

The incidence of such complications is quite low, but as some carry with them a significant degree of morbidity the need to follow manufacturers’ advice is underlined. They include regurgitation and aspiration of gastric contents, compression of vascular structures, trauma, and nerve injury. This review highlights the types and incidence of these complications.

Despite this, the use of these device may be associated with various complications including aspiration. Some devices now have features mitigating risk of aspiration, such as drain tubes or compartments to manage regurgitated content. Supraglottic airway devices are routinely used for airway maintenance in elective surgical procedures where aspiration is not a significant risk and also as rescue devices in difficult airway management.
