title: The use of double-needle canula method for temporomandibular joint arthrocentesis: clinical report.
abstract: OBJECTIVE
  The purpose of this study is to demonstrate a temporomandibular lavage instrument with double needles in a single canula that make the procedure easier for surgeons.
  
  
  METHODS
  38 year old woman was referred to our department with pain on the right temporomandibular joint (TMJ) region and restricted mouth opening. Magnetic resonance imaging reveals anterior disc displacement without reduction of the right TMJ. TMJ lysis and lavage was performed with double needle canula method.
  
  
  RESULTS
  The upper joint space was successfully lavaged with 50 mL of 0.9% saline solution. Maximal mouth opening and lateral jaw movement increased and jaw functions improved immediately after the procedure.
  
  
  CONCLUSIONS
  It is recommended as a simple alternative to classical arthrocentesis with two needles that it is easy to use and enables to perform lysis and lavage with a single puncture.
