Summary:The loss of midface structures always leads to significant functional and cosmetic deficits, and the reconstruction work remains a challenge for surgeons. We report a rare case with severe midfacial defects involving the maxilla, nasal bone, and zygoma. This patient was treated with a comprehensive approach that included distraction osteogenesis, computer-aided surgery, a fibula bone graft, dental implantation, orthognathic surgery, and rhinoplasty. The treatment procedures required 4 years to complete, and a dramatically improved facial contour and stable occlusion were achieved. The results demonstrated the importance of a multidisciplinary approach and computer-aided design when treating severe maxillofacial deformities. Other important elements of the treatment process were the meticulous physical examination, the selection of an optimal treatment sequence, the skill of the surgeons, and more importantly, the patient-oriented mindset.

“…Phillips et al, reported the first laboratory zygomatic distraction using an external distractor on the canine model [51]. Capote Moreno et al, performed zygomatic distraction osteogenesis for correction of midfacial support after hemimaxillectomy [52]. Zygomatic distraction was found to be an excellent treatment regime in patients with severe maxillary defects with insufficient bone and in whom other reconstructive methods have failed.…”

Distraction osteogenesis has emerged as an effective treatment modality for the correction of bone anomalies and abnormalities which are either pathological or developmental in origin. Earlier it was predominantly used in orthopaedics for the correction of axial skeleton. Its use in the field of dentistry began in the late twentieth century. Successful results from the initial clinical trials prompted more and more researchers to explore this field. Its use in dentistry involves the correction of craniofacial anomalies, alveolar ridge for the prosthetic rehabilitation and recently for the regeneration of lost periodontium.

“…The zygomatic bone serves as a potential landmark in the assessment of facial aesthetics along with maxilla. 1 It is a quadrangular shaped bone surrounded by facial bone, temporal bone and the maxilla. Zygoma anchorage system (ZAS) has lately been the area of interest among orthodontist as it has proven to be potential for securing skeletal anchorage devices that are utilized to assist various tooth movements like distalization of buccal segment in class II cases, intrusion of posterior segment for open bite correction.…”

Aim:The purpose of this cross-sectional study is to signify malar bone anatomy and to obtain linear correlation with varied skeletal pattern by utilizing cone beam computed tomographic views. Materials and methods:The experimental sample consisted of cone-beam computed tomography (CBCT) scans of 30 patients taken for the purpose of orthodontic treatment and peri implant planning (16 males and 14 females), 11-30 years of age (mean, 23.4 years). The sex and age were documented for all samples and nine landmarks were evaluated. The various CBCT were categorized into different malocclusions based on wits appraisal. Its prevalence was collated with age, sex and various malocclusion by Chi-square test. Results: Age and gender altogether influenced M1. The mean posterior zygomatic bone width (M1) for all sample was 63.7 mm. For M1 estimations, no huge contrast was observed among left and right side (p = 0.915). The mean anteriorzygomatic bone width (M2) was 51.8 mm. No noteworthy contrast amongst two sides (p = 0.995) or age (p = 0.067) was seen. Although sex altogether influenced M3 variety (p = 0.003), the mean greatest cortical thickness (max CT) (M4) was 9.36 mm, significant difference was observed between the minimum cortical thickness of skeletal class I and skeletal class III malocclusion design. Conclusion:Detailed evaluation of malar bone should be performed prior to any ortho-surgical procedure using CBCT. Clinical significance: Our study signifies the importance of consideration of zygoma during any pre-treatment evaluation of skeletal malocclusion. It also marks the pivotal role of zygoma while considering gross facial esthetics. Precise assurance of zygomatic bone size may likewise aid the choice of fitting surgeries and determination of zygomatic implant area.
