Horner syndrome after temporomandibular joint arthroscopy: a new complication.

healthy 58-year-old woman had undergone arthrosopy of both temporomandibular joints because of ilateral mandibular clicks and recurrent episodes of aw block that did not respond to nonsurgical treatent. The preoperative examination showed general estriction of mandibular motility (maximal oral aperure 26 mm, right and left lateral deviation 11 and 8 m, respectively, protrusion 10 mm, and dental eroion without significant muscular contractures). Magetic resonance imaging demonstrated bilateral anteior disc displacement with reduction and restricted otility of the right condyle (Fig 1). Uneventful arthroscopy of both joints was perormed under general anesthesia, after conventional asotracheal intubation. The head was placed in a donut,” in a natural position, not overextended, with mild tilt. The double puncture technique was used first, 4 mL of a mixture of lidocaine and adrenaline as injected into the superior joint space using a 3-gauge needle, followed by continuous perfusion of actated Ringer’s solution). During the procedure, the
