The incidence and risk of developing trismus is effectively related to the proximity of the tumors to the masticatory muscles. Surgical resection, scarring, and postoperative radiation in such areas are risk factors for developing trismus. 1 The insertions of the internal pterygoid and masseter muscles to the mandible or their resection also during a posterior maxillectomy explain why such locations, together with the retromolar trigone, have been described as risk factors for trismus. 2 Our study 3 didn't however show any differences in trismus release surgery and microsurgical reconstruction results depending on the initial tumor location. It did reveal though that the results were more related to the previous resections performed rather than the tumor location. This could be because the resections involved in different or even in the same locations can be very heterogeneous. For example: a soft palate resection may include or not a posterior maxillectomy, and a buccal resection can include or not a posterior maxillectomy or mandibulectomy. Therefore it makes sense that what really determined the outcome was indeed the type of resection performed rather
