“…So, it is usually underdiagnosed, but a thorough background anatomical knowledge can help in examining the patient clinically and radiologically. 14,15 This ultimately will help in the line of management and a better clinical outcome. 16 The coronoid process can be removed intra-orally without any functional deficiency and facial disfigurement.…”

The Coronoid process is a triangular upward projection from antero-superior part of ramus of mandible giving attachment to two important muscles of mastication. Aims: The aim of our study was to observe the variations in shape and size of coronoid process and establish the morphometric profile in Indian population. Materials and Methods: The material for this study comprised of 500 adult human mandibles. The shape of coronoid process was observed and its height and length were measured. Results: Three variants of coronoid process were observed (round, triangular and hook) with incidence percentage 46, 42 and 12 respectively. The mean value of height and length of coronoid process came out to be 60.62 mm and 12.53 mm respectively. Conclusions: This morphometric treatise provides valuable inputs relevant for anthropological comparisons, forensic investigations and reconstructive procedures.

“…Intraoral removal of this process causes no functional defects or facial malformations. Thus, this bone can be used for reconstruction of orbital floor defects, alveolar defects, nonunion mandibular fractures, sinus augmentations, reconstruction of bone abnormalities, and other craniomaxillofacial surgical procedures [1] .…”

The coronoid process is a beaklike process in the ramus of the mandible. Coronoid process hyperplasia (CPH) is a rare possible cause of reduced mouth opening. An overgrown process interferes with mandibular rotation and lateral excursion and hence leads to restricted mouth opening (RMO). Although some factors are suggested, etiology of CPH is not completely known. Prescription of suitable radiography is necessary for an accurate diagnosis. This article reports a 30-year-old man with bilateral CPH and progressive RMO since childhood. This disorder affected his oral hygiene and quality of life. With the help of different types of radiography, CPH was diagnosed and coronoidectomy was the only treatment option. The patient showed normal jaw movements after the surgery and postoperative physiotherapy. General dentists have an important role in noticing RMO and referring the patients to maxillofacial radiologists. Although it is a rare phenomenon, general dentists need to keep CPH in mind as a possible cause. Panoramic imaging accompanied by computed tomography or cone beam computed tomography is the best imaging option in such cases.

“…16 . The length of the coronoid process was found to be longer on the left side than the right side, this may be due to genetic factors, functional factors, and hormonal impact on muscle growth, bone remodelling and probably lead to enhanced functional stress on mandible due to mastication 17 .…”

Background:The coronoid process of mandible is thin flat triangular process from the ramus of the mandible. This varies in the shapes and size. It gives attachment to two main muscles that is temporalis and masseter muscle. The coronoid process is the favourable donor site. A Coronoid process graft can be used for alveolar defects repair, orbital floor repair, maxillary augmentation, repair of non-union fracture of mandible. These grafts can be widely used in the reconstruction of osseous defects in oral and maxilla-facial region. Aim of the Study: This study is done to find out the variation in shape of coronoid process of mandible, Intercoronoid distance, coronoid-condylar distance and the length and breadth and thickness of the coronoid process of mandible. Methods: The study was done on the 100 dry human mandibles from the osteology bank of Saveetha medical college and hospital. The distance was measured using the digital vernier callipers and the values were analysed. Results: This study is useful for the maxillofacial surgeon and this useful for determining the buccal vestibule during denture fabrication and helps us to understand the angle and extent opening of the mouth. INTRODUCTION:The mandible is the largest, strongest bone of the facial skeleton and it is the second bone in the body to ossify. It has a horizontally curved body and two vertically placed rami that ascend in the posterior aspect. The rami bear the coronoid and the condylar process. The coronoid process projects upwards and slightly forwards as a triangular plate of bone. Its posterior border bounds the mandibular incisures and its anterior border continues into that of the ramus.
