“…The LMA also has the potential to interfere with upper and lower oesophageal sphincter tone and cause subclinical regurgitation 9 . There have also been reports of lingual nerve 10,11 , inferior alveolar nerve 12 recurrent laryngeal nerve 13,14 and hypoglossal nerve injuries 15 following the use of an LMA. It is suspected this was caused by pressure and restriction of the nerves involved by the incorrect placement of the LMA.…”

Aims: We have developed a technique to secure the LMA without obstructing the surgical field and have minimal interference with airway maintenance. Nasal endo‐tracheal tube is the gold standard for airway maintenance; however, it can slow turnover time due to it requiring a longer recovery time compared with the laryngeal mask airway (LMA). The LMA position often obscures the surgical field in these cases often necessitating repositioning intra‐operatively. This can adversely affect airway patency. Materials and methods: We audited two different techniques of securing LMAs (north‐facing with our modification vs. south‐facing conventional taped to the lower lip/chin) in a total of 223 patients undergoing bilateral extractions. A questionnaire for surgeons and anaesthetists was used to assess their suitability and complications occurred noting particularly obstructions caused to the LMA, cause for obstruction, management taken to correct obstruction. Results: We found the risk of partial or total obstruction of the airway during surgical extractions with a conventionally placed LMA to be around 36% compared with 19% with a retromolar positioned flexi‐LMA during our study. Conclusion: The retro‐molar positioned LMA not only increased operating space but showed a reduced number of obstructions caused to the LMA.
