We prospectively studied 10 patients who were status postenucleation and primary placement of the hydroxyapatite orbital implant. Both the technetium-99m bone scan and gadolinium-enhanced magnetic resonance images (MRI) were obtained on the same day at variable time points in the postoperative period in order to assess the degree of vascularization. Up to 78% of the bone scans were interpreted as being completely vascularized, while only 10% of the corresponding MRI scans were consistent with complete vascularization. Cost analysis showed that MRI was cost-effective imaging modality. We conclude that contrast-enhanced MRI provides a more accurate assessment of vascularization of the hydroxyapatite orbital implant when compared to bone scan.

Department of Oral and Maxillofacial Surgery, SDM Craniofacial Unit, SDM College of Medical Sciences and Hospital, Dharwad, Karnataka, India.
Objectives Of The Study: (1) To evaluate the effect of platelet-rich fibrin (PRF) with bone marrow aspirate on regenerative capacity in patients undergoing iliac bone grafting for secondary alveolar bone grafting. (2) and to compare it with group 2 where only bone marrow aspirate was used along with iliac bone graft in secondary alveolar bone grafting.
Materials And Methods: A prospective study on patients with cleft alveolus, requiring bone grafting and reporting to our unit from October 2018 to October 2020 was included in this study.

Jansen metaphyseal chondrodysplasia (JMC) is an ultra-rare disorder caused by constitutive activation of parathyroid hormone type 1 receptor (PTH1R). We sought to characterize the craniofacial phenotype of patients with the disease. Six patients with genetically confirmed JMC underwent comprehensive craniofacial phenotyping revealing a distinct facial appearance that prompted a cephalometric analysis demonstrating a pattern of mandibular retrognathia.

Cherubism is a rare autosomal dominant skeletal dysplasia, affecting the maxilla and/or mandible. The condition typically has childhood onset, followed by progression until puberty, with subsequent regression. Cherubism lesions share histological features with giant cell tumor of bone, where high-dose monthly denosumab is an effective medical treatment.

Lung cancer exhibits a diverse array of morphological manifestations and molecular changes, significantly influencing patient diagnosis, prognosis, and treatment strategies. We present the case of a 47-year-old man with a history of smoking, who presented to the emergency room with a 12-month history of haemoptysis. A chest computed tomography (CT) scan revealed a mass in the right upper lobe of the lung and bilateral lung nodules.
