A modified single-puncture technique for temporomandibular joint arthrocentesis using a peripheral intravenous catheter: Case Report

Arthrocentesis is a minimally invasive surgical procedure widely used for the management of inflammatory temporomandibular joint (TMJ) disorders. Although the conventional two-needle technique has been well established for over two decades, recent modifications have introduced single-puncture arthrocentesis to reduce procedural morbidity. This report describes a modified single-puncture technique employing a dual-peripheral intravenous catheter assembly. The proposed modifications facilitate effective joint lavage, improve procedural efficiency, and offer technical advantages over previously described single-puncture arthrocentesis methods.
