Eruption of the Permanent First Premolar Associated with a Mandibular Keratocystic Odontogenic Tumor after Marsupialization in a 9-year-old Boy: A Case Report with 2 years of follow-up

Amongst odontogenic cysts, keratocystic odontogenic tumor (KOT) is a benign intra-osseous lesion, characterized by corrugated parakeratinized uniform stratified squamous epithelium, with potential for aggressive behavior and high tendency to recur. There are multiple treatment modalities for this cyst. Some surgeons prefer the conservative treatments such as marsupialization while the others prefer invasive treatments such as radical resection. The aim of this study was to present a case of KOT involving the right mandibular premolar area with an impacted tooth in a 9-year-old boy treated by marsupialization. The treatment resulted in eruption of the mandibular first premolar, and no signs of recurrence were observed after two years. Marsupialization was found to be an effective treatment in inducing the eruption of mandibular premolar associated with KOT in preadolescents and can be a reliable procedure to reduce recurrence tendency of KOT

Evaluation of Pre- and Post-operative Hemoglobin in Patients with Maxillofacial Injuries

Background: In the past decades, a significant increase has been observed in head and face traumas bleeding during and after surgery is one of the most important and dangerous factors for patients. This study was performed to assess the bleeding amount in patients during maxillofacial surgeries and the necessity of blood transfusion.Methods: In this cross-sectional study, 441 patients were enrolled, of which 83.2% and 16.8% were male and female, respectively. To compare the patients’ mean hemoglobin concentration before and after surgery, paired t-test was used. Furthermore, to compare the mean hemoglobin concentration and mean intraoperative bleeding between males and females, independent t-test was used. The significance level was set as 0.05 for all tests.Results: Results showed that the mean difference of hemoglobin concentration before and after surgery in patients of the study had a significant difference (P < 0.001). The amount of blood loss during surgery showed no significant difference between males and females (P > 0.050).Conclusions: The results of this study demonstrated that there was a decrease in mean hemoglobin concentration after surgery, and also, the amount of blood loss in patients during surgery was not high enough for blood transfusion. However, it should be considered that to prevent any problem during surgery, assessing patients with anemia before surgical operations is necessary

Misdiagnosis of Adenoid Cystic Carcinoma of Palate: A Case Report

Introduction: Neoplasms of the salivary glands are uncommon, accounting for approximately 3 to 5 percent of all head and neck tumors. Adenoid cystic carcinoma (ACC) is a rare salivary gland malignancy with a poor survival rate because of a high rate of late local recurrence and distant metastasis.   Materials and Methods: This paper reports a misdiagnosis of palatal ACC via fine needle aspiration cytology (FNAC). A 27-year-old female with painful swelling in the right side of the palate underwent FNAC and was misdiagnosed with pleomorphic adenoma. During surgery, hemi-maxillectomy was performed due to the fragile consistency of the tissues. Result: The tumor was found to be ACC after histopathologic evaluations. Hence, the patient underwent radiotherapy and chemotherapy postoperatively. Conclusion: Given specific limitations and diagnostic pitfalls, it seems that pre neural and pre vascular invasion of tumors as a sign of malignancy should be noticed
