Ultrasound-guided measurement of hyomental distance (HMD), an indicator of submandibular space, has emerged as a promising anatomy-based alternative. This study aimed to compare the efficacy and safety of ultrasound-guided HMD-based sizing with conventional weight-based sizing of the ProSeal LMA\u2122 (Teleflex Inc., Wayne, PA, USA) (PLMA) in adult patients undergoing elective surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This prospective, double-blinded randomised controlled trial included 116 American Society of Anesthesiologists (ASA) physical status I\u2013II adults aged 18\u201360 years scheduled for elective surgery under general anaesthesia. Patients were randomised into two groups: Group A underwent PLMA size selection based on body weight, while Group B underwent ultrasound-guided HMD-based size selection. The primary outcome was first-attempt insertion success. Secondary outcomes included insertion time, number of attempts, need for reinsertion, and postoperative oral injury.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Demographic characteristics were comparable between groups. First-attempt insertion success was similar in both groups (93.1% in weight-based group vs. 96.6% in HMD group;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.67). The mean insertion time was comparable (18.1 \u00b1 4.8 s vs. 18.5 \u00b1 4.6 s;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.60). The HMD group predominantly received smaller PLMA sizes (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.001) without increased reinsertion rates or complications.
