During 2011-2012, 56 patients diagnosed with parotid tumors were admitted to the Maxillofacial Surgery Department of “Lucian Blaga” University and in Euroclinic Hospital. 72% were benign tumors and 28% malignant. All patients received surgical treatment (total or partial parotidectomy). For the malignant tumors, radiotherapy was added to the modal treatment (94% of the cases). Pleomorphic adenoma was encountered in 70% of the benign cases, followed by Warthin tumor in 15%. Adenoid cystic carcinoma was noticed in 31% of the malignant cases, mucoepidermoid carcinoma in 25% of the cases, and squamous carcinoma and non-Hodgkin lymphoma on 12.5% of the malignant cases.

Background: Salivary gland tumors include a wide variety of benign and malignant tumors in the oral and maxillofacial region. Although these tumors are not common, they are not rare. The prevalence of these tumors varies with regard to age, gender, and their location in the body. Objectives: This study aimed to evaluate the frequency of benign and malignant salivary gland tumors in patients referred to three referral hospitals in Tehran, Iran. Methods: This retrospective cross-sectional study examined the demographic and pathologic records of the patients with salivary gland tumors submitted to the Department of Pathology of Amir Alam, Loghman Hakim, and Shohada Hospitals from 2005 to 2016. In this study, the histological variants of salivary gland tumors and clinical parameters such as age, gender, and the location of the tumor were examined. The clinical data were analyzed using SPSS software version 21. Results: Of 137632 patient records, 1180 cases were salivary gland tumors. Pleomorphic adenoma in 794 cases (67.3%) and adenoid cystic carcinoma in 109 cases (9.2%) were the most common tumors, respectively. Salivary gland tumors were more common in males, and the participants’ mean age was 42.86 ± 16.5 years. The most common site was parotid and minor salivary glands, with 937 (79.4%) and 137 (12%) cases, respectively. Conclusions: In this study, the most common benign tumor was pleomorphic adenoma in the parotid gland, and the most common malignant tumor was adenoid cystic carcinoma in the major salivary glands. Furthermore, benign tumors were more frequent than malignant tumors.

Introduction: Sarcomas are a rare group of malignant tumors. This study highlights important findings in 91 cases of non-odontogenic sarcomas of the orofacial region. Materials and Methods: Patients who presented with orofacial sarcoma at the Oral and Maxillofacial Surgery Department of a regional University Teaching Hospital between January 1997 and June 2017 were retrospectively studied. Excluded were cases of Kaposi and odontogenic sarcomas. Data obtained were analyzed using the Statistical Package for Social Sciences (SPSS) version 16 (SPSS Inc., Chicago, IL, USA). Results from descriptive statistics were represented in the form of charts. Results: A total of 91 cases were reviewed and consisted of 51 (56.0%) males and 40 (44.0%) females, with a male to female ratio of 1.3:1. The mandible (n=47; 51.6%) and the maxilla (n=26; 28.6%) were the major sites involved. Osteogenic sarcoma (n=44; 48.4%) and rhabdomyosarcoma (n=16; 17.6%) occurred more frequently. A total of 41 (45.1%) patients had surgery and the common hard tissue procedures were mandibulectomy (n=26; 28.6%) and maxillectomy (n=10; 11.0%). Non-surgical oncological treatment was administered to 32 (35.2%) patients, and this was the only modality of treatment in 8 (8.8%) cases. The period of follow-up Arranged from 1-43 months and within this period; there were 7 (17.1%) recurrences with 1 case of pulmonary metastasis. Discussion: Most recurrences were noted less than one-year post-treatment. There is a tendency for patients to present late and compliance with follow up review is poor in this environment.

This paper presents our experience of the problem of diagnosis and surgical treatment of malignant parotid tumors, based on a retrospective evaluation of a series of 478 parotid tumors, of which 100 were malignant. Out of 75 primaris malignant tumors of epithelial origin, 35 belonged to the « epidermoid » group (adenocarcinomas, undifferentiated carcinomas, malignant mixed tumors, squamous cell carcinoma), 20 were muco-epidermoid carcinomas, 15 adenoid cystic carcinomas and 5 were acinic cell carcinoma. Altogether, 58.7% of the treated patients do not at the moment present evidence of disease; 33.3% are dead from the disease or are alive with active disease; 5.3% are dead from other causes and 2.7% are lost to follow-up. Underlining the importance of histologic examination of the swelling by intraoperative biopsy, the authors propose a diagnostic and therapeutic protocol.

ABSTRACT Objectives Salivary gland neoplasms are uncommon, but they are of much interest and debate because of their remarkable variability in structure, clinical presentation, and behavior. We have studied 56 cases of parotid tumors and shared our views on the diagnosis and management of these rare tumors. Materials and methods Fifty-six patients with parotid swelling presented to us over a period of 5 years. Preoperatively, all these patients were evaluated with fine needle aspiration cytology (FNAC). Depending on the report, they were subjected to further treatment. Results Out of 56 cases, 44 (79%) were benign and 12 (21%) were malignant. Pleomorphic adenoma being the commonest benign tumor [32 cases (72%)] and among the malignant tumors, mucoepidermoid carcinoma was the commonest. Parotidectomy is the gold standard treatment for both the benign and malignant parotid tumors. Conclusion Parotid tumors are a rare entity. Among which benign tumors are more common than malignant. An accurate diagnosis preoperatively and timely surgical management would reduce the recurrence rate and risk of complications.

Knowledge Gaps

Objectives: The aim of this study was to evaluate available knowledge and identify knowledge gaps within the field of oral and maxillofacial surgery, by systematically collecting and evaluating systematic reviews. Twelve specific domains were selected: surgical removal of teeth, antibiotic and corticosteroid prophylaxis, orofacial infections, dental and facial trauma, orthognathic surgery, reconstructive surgery, benign tumors, cysts, premalignant lesions, oral complications of treatment of malignant tumors, hyperbaric oxygen therapy, temporomandibular joint surgery, cost effectiveness of different surgical treatments, and ethics.Methods: The literature search, covering four databases, was conducted during September 2014: PubMed, The Cochrane library, Centre for Reviews and Dissemination and EBSCO dentistry and oral science source. Retrieved systematic reviews were quality assessed by AMSTAR.Results: In all, 1,778 abstracts were identified, of which 200 met the inclusion criteria. Forty-five systematic reviews were assessed as of high to moderate quality. The results disclosed some existing evidence in a few domains, such as surgical removal of teeth and implant survival after sinus lifts. However, in all domains, the search revealed a large number of knowledge gaps. Also of concern was the lack of data regarding health economics and ethics.Conclusions: In conclusion, there is a need for well-conducted clinical research in the fields of oral and maxillofacial surgery.

Conventional Ct

To determine the most appropriate radiographic approach to parotid tumors, computed tomography (CT) was performed in 65 patients with 33 benign tumors, 19 malignant tumors, 3 abscesses and 10 other lesions with a clinical appearance of tumor. In 22 of the 65 cases CT-sialography and in 26 ultrasonography (US) were also performed. The mass was well recognized on CT without sialography in all patients, and the lesion was also well evaluated in all those examined with US. At CT-sialography the tumor was well shown, but this method made it difficult to differentiate a benign from a malignant lesion, because the character of the delineation and the border of the tumor were difficult to evaluate. It is concluded that US and CT without sialography are satisfactory for evaluating the parotid tumor, and the indication for CT-sialography is limited to those cases in which the tumor is demonstrated on US, but is unclear on conventional CT.

Objective The purpose of this study was to analyze and compare the value of fine-needle aspiration cytology (FNAC) and frozen section (FS) analysis in the assessment of parotid gland tumors. Study Design Chart review and cross-sectional analysis. Subjects and Methods FNAC and FS analysis of 110 parotid tumors, 68 malignancies and 42 benign tumors, were analyzed and compared with the final histopathologic diagnosis. Results The accuracy, sensitivity, and specificity of FNAC in detecting malignant tumors were 79 percent, 74 percent, and 88 percent, respectively. On FS analysis, the accuracy, sensitivity, and specificity in detecting malignant tumors were 94 percent, 93 percent, and 95 percent, respectively. The histologic tumor type was correctly diagnosed by FNAC and FS in 27 of 42 (64%) and 39 of 42 (93%) benign tumors, respectively, and in 24 of 68 (35%) and 49 of 68 (72%) malignant neoplasms, respectively. Conclusion The current analysis showed a superiority of FS compared with FNAC regarding the diagnosis of malignancy and tumor typing. FNAC alone is not prone to determine the surgical management of parotid malignancies.

Objective Histology of parotid tumors determines the extent of surgery. The aim was to test ultrasound (US) contrast enhancer-kinetics to identify histologic entities, possibly being superior to qualitative morphological parameters. Study Design In a cross-sectional assessment of ultrasound diagnosis, the subjective US-classification was compared with contrast analysis with histology as gold standard. Subjects and Methods A total of 64 male and 61 female patients with a mean age of 54 years were included, with 13 malignant tumors. These were classified with US morphology, then time-dependent contrast medium analysis. Results A total of 92.8% of tumors were classified correctly as malignant or benign. The sensitivity, specificity, positive- and negative-predictive values were 66.7%, 86.3%, 60.6%, and 89.1% for differentiating Warthin tumors, but only 46.2%, 98.2%, 75%, and 94% for malignant lesions. Contrast parameters yielded significant parameters for benign tumors, not for malignant entities. Conclusion Although contrast medium analysis provided statistical criteria, these, however, do not possess the ability to improve the diagnostic prediction of tumor histology. Neither the morphologic classification nor contrast medium analysis was able to identify a malignant lesion sufficiently.

Abstract INTRODUCTION The frequency of intraorbital tumors is small as 0.9% of all brain tumors, but its pathological type is diverse. Among them, the diagnosis of whether particularly malignant tumor scan clinically, is extremely important. Nuclear medical testing is essential for non-invasive differential diagnosis in brain tumors. SPECT, good malignancy differentiation, evaluation of malignancy, usefulness such as differentiation of non-tumorous lesions have been reported many. However, there are few reports that SPECT was useful in preoperative differential diagnosis of orbital tumors. Since 123IMP-SPECT was useful in preoperative differential diagnosis of intraorbital tumors, we report some literature considerations. METHOD Among the 27 cases of intraorbital tumors that were operated on in our clinic between August 2005 and August 2016, 14 cases of SPECT prior to surgery were examined for the usefulness of preoperative differential diagnosis. Breakdown of cases, as the malignant tumor, two cases of malignant lymphoma, MALT lymphoma 2 cases, adenoid cystic carcinoma 1 case, in one case plasma cytoma, as a benign tumor, false tumors 4 cases, three hemangioma cases, neurocytoma 1 case it was. RESULTS In IMP early image, accumulation of clear IMP was observed in all six cases of malignant tumors. In benign tumors, there is no accumulation in hemangioma and neurosheath, there is a strong accumulation in one of the four cases in false tumors, it was observed mild accumulation in the remaining two cases. Tumor to normal ratio of IMP early image was an average of 2.39 in six malignant tumors and 1.52 in 8 benign tumors. CONCLUSION This time, we examined the usefulness of 123IMP-SPECT in preoperative differential diagnosis of intraorbital tumors. The T/N ratio of intraorbital malignant tumors is higher than benign tumors, and it was thought to help to evaluate preoperative malignancy of intraorbital tumors.

INTRODUCTION: With a probability of 50% malignancy, salivary gland tumors are not too commonly noticed in children and adolescents. Most of these have idiopathic etiology but a few pre-disposing factors have been reported in literature. We hereby report eighteen cases of paediatric salivary gland tumors in a study conducted from September 2013 to August 2018 at department of Oral and maxillofacial surgery at Tatyasaheb Kore Dental college and Research Centre, Kohlapur, Maharashtra, India..AIM & OBJECTIVES: This study aimed to inspect the distribution, clinical and histopathological features of salivary gland tumours in children and adolescents.MATERIAL AND METHODS: A total of 18 cases of salivary gland tumors encountered in paediatric age group were studied and explored for age, gender, site proneness and for histopathological nature.RESULTS: Female gender had a predominance over males. Parotid tumors were more common (77.78%) as compared to tumors of submandibular glands. Six cases were diagnosed with benign tumors (pleomorphic adenoma) and rest had malignant tumors (mucoepidermoid in nature). Majority of the cases did not report undergoing any prior treatment.CONCLUSION Present study revealed that salivary gland tumors in paediatric age group are quite rare with female gender being more prone. With majority of cases being mucoepidermoid in nature, parotid gland is most commonly affected.
