Ligmaject system for local anaesthesia in otology

Area of Science:

• Otolaryngology
• Anesthesiology
• Medical Device Engineering

Background:

• Accurate and controlled local anaesthetic delivery is crucial in otological procedures.
• Conventional syringes may offer limited precision for micro-injections.
• Novel delivery systems are needed to improve patient experience and procedural efficiency.

Purpose of the Study:

• To evaluate the efficacy and patient acceptability of the Ligmaject syringe for local anaesthesia in otological surgery.
• To compare the Ligmaject syringe with conventional dental syringes in terms of user convenience and patient outcomes.

Main Methods:

• The Ligmaject syringe, featuring a pistol-grip and ratchet mechanism for precise aliquots, was employed.
• Local anaesthesia was administered using the Ligmaject for 22 otological procedures on adult patients.
• Patient acceptability and user convenience were assessed and compared to standard dental syringes.

Main Results:

• The Ligmaject syringe demonstrated favorable performance in providing local anaesthesia for otological procedures.
• Patient acceptability was high, indicating a positive experience with the novel syringe.
• User convenience for clinicians was comparable to, or better than, conventional dental syringes.

Conclusions:

• The Ligmaject syringe is a viable and effective tool for delivering local anaesthesia in otological surgery.
• Its design facilitates precise delivery, potentially improving patient comfort and procedural control.
• The Ligmaject syringe presents a user-friendly and acceptable alternative to conventional syringes in this clinical setting.
