Contralateral coronoid process bone grafts for orbital floor reconstruction: an anatomic and clinical study.
The first is characterized by the joint between the coronoid process and the jawbone, accompanied by cartilaginous structures and the formation of a synovial capsule [8].
Caption: Figure 1: 3-Dimensional reconstruction of CT imaging shows recurrent tumour of the grafted bone and remnant coronoid process.
Caption: Figure 2: OPG showing large unilateral radiolucencies extending from the 1st permanent molar along the ascending ramus up to the neck of the condyle and involving coronoid process and thinning of the lower border and bowing of angle of mandible.
In the computed tomographic examination of the 35-year-old male patient who was referred from the emergency unit of the medical faculty to our clinics with the complaints of post-traumatic limited mouth opening and pain, a fracture line was observed in the left zygomatic arch region with a displaced angled inward in a "greenstick" style, where the mandible was in contact with the coronoid process (Figure 1).

Orthopantomograph revealed a well defined unilocular radiolucent lesion with sclerotic radiopaque marginsextending from 37, involving impacted third molar, ramus up to coronoid process and subcondylar region of right side of mandible (Figure 2).
Common symptoms of CCD include hypoplasia or aplasia of the clavicles, delayed or even absent closure of fontanels, midface hypoplasia, short stature, delayed eruption or impaction of permanent and supernumerary teeth, as well as other skeletal malformations, such as wide pubic symphysis, brachycephalic skull, and abnormal mandibular ramus and coronoid process.[sup][1],[2] Among the various phenotypic spectra of CCD, hypoplasia or aplasia of the clavicles and dental abnormalities are common.
Mandibular alterations may be unilateral or bilateral and include enlarged mandibular and mental foramen, widened inferior alveolar canal, branching of mandibular canal, hyperostosis, deepened sigmoid notch, elongated condylar neck, rarefied condylar and coronoid process, medial concavity in mandibular ramus, decreased or flat gonial angle, irregular inferior cortex, and cyst like lesions [1-4, 6].
(63) The ulna is displaced posteriorly relative to the humerus, resulting in impaction of the coronoid process against olecranon and posterior capitellum against the radial head (Figure 13).
(1) The most common sites are the long tubular bones, especially the femur, humerus, and tibia) In the maxillofacial region, they are most common in the mandible, the condylar area, and the tip of the coronoid process. (2) To the best of our knowledge, involvement of the nasal bone has not been previously described.
