Pressure Infusor Assisted Arthrocentesis

Area of Science:

• Oral and Maxillofacial Surgery
• Orthodontics
• Biomedical Engineering

Background:

• Temporomandibular joint (TMJ) internal disorders often cause limited mouth opening and pain.
• Treatment strategies vary from conservative to surgical interventions.
• Current arthrocentesis techniques may lead to operator fatigue and inconsistent irrigation flow.

Purpose of the Study:

• To introduce a novel modification to arthrocentesis for TMJ internal disorders.
• To utilize a pressure infusion cuff for enhanced irrigation control and operator comfort.
• To improve patient compliance and enable quantitative data collection.

Main Methods:

• A pressure infusion cuff (VBM Classic Infusor) was adapted for TMJ arthrocentesis irrigation.
• The cuff system replaced traditional syringes or peristaltic pumps for fluid delivery.
• Continuous pressure monitoring via the cuff's integrated sphygmomanometer was employed.

Main Results:

• The pressure infusion cuff provided stable and efficient irrigation flow throughout the procedure.
• The technique reduced operator hand and wrist strain associated with manual irrigation.
• Pressure monitoring allowed for real-time adjustments, enhancing patient comfort and compliance.

Conclusions:

• The modified arthrocentesis technique using a pressure infusion cuff offers a viable alternative for TMJ internal disorder treatment.
• This method improves procedural efficiency, operator ergonomics, and patient experience.
• The system facilitates objective pressure monitoring, beneficial for clinical studies and data acquisition.
