Clinicopathological Analysis of 907 Major and Minor Salivary Gland Tumors.

PURPOSE: The frequency and types of salivary gland tumors show significant geographical variations. The most common are primary epithelial tumors, with pleomorphic adenoma and mucoepidermoid carcinoma being the most frequent. This study aims to analyze the clinicopathological data of patients with major and minor salivary gland (MiSG) tumors. METHODS: The retrospective study included all patients with major and MiSG tumors diagnosed and treated between January 2000 and January 2019. Files of 907 patients were reviewed and investigated for clinicopathologic features of major and MiSG tumors in Serbia. RESULTS: The majority of tumors were of epithelial origin. Pleomorphic adenoma was the predominant type of tumor, with 35.1% among all tumors on all sites. Adenoid cystic carcinoma and mucoepider-moid carcinoma (with 7.1% and 2.7%, respectively) were the most common malignant ones. The most common localization was the parotid gland. Minor salivary gland tumors comprised 16.43% of all salivary gland tumors in our series, the most common localization being the oral cavity. The results of our study are mostly consistent with the results of other previously published studies. CONCLUSIONS: The most important finding, worth emphasizing, is that the most common malignant major and MiSG tumor in our population is adenoid cystic carcinoma, rather than mucoepidermoid carcinoma, in all investigated localizations. In addition, the nasal cavity is the most common localization among malignant MiSG tumors.

Effectiveness of the Treatment of Rhinogenic Headache Caused by Intranasal Contact.

OBJECTIVES: The aim of the study is to evaluate the effectiveness of the surgical and nonsurgical treatment of headache caused by contact points (CPs) between the nasal septum and inferior or middle turbinate. METHODS: The research was designed as a prospective clinical case-series study. The patients with CP headaches were offered to choose between 2 treatment options, surgery and medical treatment. Two groups of surgically treated patients (surgery groups 1 and 2, depending on whether there is a contact between nasal septum and inferior turbinate or middle turbinate) were evaluated and compared for headache intensity and frequency. Headache intensity was measured using a visual analog scale value from 0 to 10; the frequency of headache was expressed as the number of days during 1 month with a headache (before surgery, 1 month, and 6 months after surgery). A comparison was also made between surgically and nonsurgically treated patients. RESULTS: We found more intensive and frequent headache in patients who had CP between the nasal septum and the middle turbinate (P = .038 and P = .003, respectively). A significant reduction in headache intensity and frequency was found in both groups of surgically treated patients 6 months after surgery; however, this reduction was more significant in patients with mucosal contact between nasal septum and middle turbinate. The nonsurgical treatment made a significant reduction of headache intensity and frequency at 1-month follow-up (P = .012 and P = .031, respectively), but not at 6-month follow-up (P = .114 and P = .088, respectively). CONCLUSION: Surgery gave a statistically significant reduction in the intensity and frequency of headache, which was assessed 6 months after surgery. Surgery was found as superior to nonsurgical treatment in the therapy of CP headache.

[Surgical approach to parapharyngeal space tumors].

INTRODUCTION: Parapharyngeal space tumors are very rare comprising 0.5% of head and neck tumors. Tumors of this symptomatology as well as considerable surgical issue owing to inaccessibility. PATIENTS AND METHODS: Retrospective twenty-year study of patients with parapharyngeal space tumors included 69 patients. Data were obtained from medical records, and were pointed to diagnostic procedures, surgical approach and pathohistological findings. Symptoms and clinical signs were also investigated. RESULTS: Preoperative diagnostics is very important for precise tumor localization and relation to adjacent structures. Computerized tomography was the most common method used, and recently, magnetic resonance imaging and indication-based contrast angiography have been applied. All of 69 patients with parapharyngeal space tumors were treated surgically. The most often approach to this tumor was transcervical (62%), then transoral approach and combination transcervical transoral approach. Pathohistological examination verified that most of the tumors were benign (75%) and origin of these tumors was most frequently salivary (42%). CONCLUSION: For making a decision on surgical approach, diagnostic methods, other than thorough examination, such as computerized tomography (CT) and/or magnetic resonance imaging (MR), are necessary to be applied.
