One of the more-common causes of this disability is a bone problem within the elbow joint called fragmented coronoid process
, or FCP.
Mandibular fracture occurs in common location like body (29%), condyle (26%), angle (25%), symphysis (17%), ramus (4%) and coronoid process
01 mm), including: greatest length of skull (GLS), condylobasal length (CBL), basal length (BL), occipitonasal length (ONL), palatal length (PL), length of palatal bridge (PBL), length of incisive formina (LIF), breadth of incisive formina (BIF), length of upper tooth row (LUTR), length of upper molars (LUM), maximum upper molars breadth (GUMB), heigth of coronoid process
of mandible (HCPM), length of lower molar row (LLMR), lower tooth row (LTR), mandibular height (MH) (Fig.
The mandible of Bibimys looks impressive by the combination of a wide and triangular coronoid process
, a bulbous capsular projection located anteriorly (Fig.
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
Hypertrophy of the Mandibular Coronoid Process
and Structural Alterations of the Condyles Associated with Limited Buccal Opening : Case Report.
Intraoral incision must be made in the mucobuccal sulcus in the superior posterior direction between the coronoid process
and maxillary third molars (15, 16).
Within the mandible, susceptible site is posterior body followed by condyle, angle, ascending ramus, coronoid process
, anterior body and sigmoid notch in descending frequency.
The patient fell on his hand with his elbow extended; an axial load from the coronoid process
and varus stress could have impacted the trochlea.
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).
