Orbital approach for retrieval of transected extraocular muscles.
Transection of an extraocular muscle can occur from orbital and facial trauma, or as a complication of surgery. The injury can occur either near the muscle insertion or in the muscle belly. Identification of the proximal end of the muscle in the orbit may be difficult, especially if the transection occurs a farther distance from the insertion, and, in these cases, the muscle is often considered lost. We present two patients who suffered from traumatic transections of an extraocular muscle more than 10 mm from the insertion. Both patients underwent transconjunctival orbitotomy to retrieve and secure the severed extraocular muscle. Both patients achieved good primary gaze alignment postoperatively. Preoperative imaging should be considered in cases of traumatic extraocular muscle transection.
