A single-puncture arthrocentesis technique, using a peripheral intravenous catheter.

Area of Science:

• Oral and Maxillofacial Surgery
• Orthopedics
• Biomedical Engineering

Background:

• Arthrocentesis is a standard procedure for treating temporomandibular joint (TMJ) disorders.
• The conventional two-needle technique involves lavage and lysis of fibrous strands in the supradiscal space.
• This classical method presents challenges and limitations in clinical practice.

Purpose of the Study:

• To introduce and describe a simplified single-puncture arthrocentesis technique for the TMJ.
• To highlight the advantages of the single-puncture approach over the traditional two-needle method.
• To present a cost-effective and feasible alternative for TMJ lavage.

Main Methods:

• A single-puncture technique utilizing a peripheral intravenous catheter for simultaneous inflow and outflow.
• Application of low or high volume irrigation for TMJ lavage.
• Description of the procedure for accessing the superior joint space of the TMJ.

Main Results:

• The single-puncture technique offers a less traumatic and easier alternative to the two-needle approach.
• Potential advantages include reduced procedure time, improved needle stabilization, and enhanced medication retention.
• The method is feasible, cost-effective, and uses readily available medical devices.

Conclusions:

• The described single-puncture arthrocentesis technique provides a viable and advantageous alternative for TMJ lavage.
• This approach simplifies the procedure, potentially improving patient outcomes and operator experience.
• The use of peripheral intravenous catheters makes this a widely accessible and economical option.
