Introduction:
Elongated mandibular coronoid process is a rare condition defined as enlargement of the coronoid process. The only useful way to treat the mouth-opening limitation is resection of the elongated coronoid process. Four-dimensional CT (4DCT; three spatial dimensions plus time axis) is a novel imaging technique. Its usefulness of for evaluation of dynamic movements such as joint motion has been reported. Here, we show the potential usefulness of 4DCT evaluation in a patient with elongated mandibular coronoid process.
Case Presentation:
A 59-year-old female who suffered from mouth-opening difficulty and pressure during mouth opening was referred to our department. Elongation of the right coronoid process was evident in a panoramic X-ray image. The mandibular movement and temporal muscle motility before and after coronoidectomy in this patient on 4DCT could be evaluated.
Conclusions:
4DCT is useful in the diagnosis and surgical outcome of elongated coronoid process.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
