{Abstract}: Hemifacial microsomia (HFM) patients may benefit from extended temporomandibular joint replacements (eTMJR) to improve function and quality of life. A cross-sectional survey was sent to surgeons who place alloplastic temporomandibular joints regarding their experience with and complications encountered when placing eTMJR in patients with HFM. Fifty-nine responded to the survey. Thirty-six (61.0%) reported treating patients with HFM and 30 (50.8%) of those reported placing an alloplastic temporomandibular joint (TMJ) prosthesis for patients with HFM. Twenty-three of the 30 surgeons (76.7%) placing alloplastic TMJ prostheses reported using an eTMJR in patients with HFM. The average maximum inter-incisal opening (MIO) after an eTMJR in HFM patients was repor ted as> 25 mm by 82.6% of the participants, and between 16 mm and 25 mm by 17.4%. No participants reported MIO < 15 mm. To avoid condylar sag and open bite changes postoperatively, over 70% reported using some form of modification to stabilize the occlusion. Respondents reported good functional outcomes for eTMJR in patients with HFM with relatively few complications. Therefore, eTMJR could be considered a viable option in the management of this patient population.
