    Opis:
    Introduction: Salivary gland tumours account for 3-6% of tumours of the head and neck. About 80% of salivary gland tumors occur in parotid glands, 10-17% of which are malignant The aim of the study was to assess whether there is an upward trend in cancer incidence within the parotid glands, with particular emphasis on cancers. Materials and methods: 322 patients underwent surgery and 328 parotid gland tumours were removed in the years 2005-2014 at the Department of Laryngology and Laryngological Oncology of the Upper Silesian Medical Centre in Katowice-Ochojec. Clinical, histopathological and statistical analyses of the removed parotid gland tumours were performed. Results and discussion: A significant increase in the incidence of benign tumours, especially mixed and Warthin tumours, was demonstrated. There was no significant increase in the number of malignant tumours over the analysed period of time.

    Opis:
    Introduction: Parotid gland neoplasms represent a heterogenous group of tumors, either benign or malignant. The diagnosis and management of parotid gland tumors is complicated by their relative infrequency and their diverse biologic behavior. Aim: The aim of this study is to investigate the epidemiological characteristics, the recurrence rates and the surgical approach employed for parotid gland tumors in Northern Greece. Material and methods: This is a single-center retrospective study. All patients admitted to the ENT department of “G. Papanikolaou” General Hospital of Thessaloniki from January 2012 to June 2019 with the diagnosis of parotid gland tumor were included in the study. Patients with incomplete charts and patients that underwent revision surgeries were excluded. Chi-squared tests were used to assess the associations between variables. Results: A total of 207 patients with a mean age of 54.97 (range 16–91) were included in the study. Benign neoplasms accounted for 87.9% of the cases. Warthin’s tumor was the most common neoplasm encountered, with an incidence of 46.8%, followed by pleomorphic adenoma (31.9%). There was a higher incidence of parotid gland tumors in males and smokers (P = 0.025, P = 0.001 respectively). The majority of the patients were treated with an extracapsular resection (60.4%) or with a partial superficial parotidectomy (22.6%). In 12 cases (5.7%), there was a recurrence of the lesion. The most common complications encountered were facial nerve injury, Frey’s syndrome and hematoma formation. Conclusions: Parotid gland tumors are typically benign, non-aggressive tumors, more frequently seen in men than women. There is a positive association between smoking and parotid gland tumor development. Comprehensive information regarding recurrence and complication rates is presented.

    Opis:
    Pleomorphic adenoma, also known as tumor mixtus, is one of the most common types of benign neoplasm of the salivary gland, which presents as a slow growing, painless tumor. Major salivary glands are the typical localization of this neoplasm. It rarely undergoes malignant transformation, however may recur locally post resection. In this study, we present the results of a retrospective analysis of 104 patients treated at the Clinical Department of Cranio-Maxillofacial Surgery, Clinic of Otolaryngology and Laryngologic Oncology of the Military Institute of Medicine between 2004 and 2015 due to pleomorphic adenoma. The study confirmed the parotid gland as the most common location of tumor mixtus. In some cases, the large size of the tumor and its location were the cause of life-threatening complications.

    Opis:
    Introduction: Tumors of large salivary glands constitute about 2–3% of all head and neck tumors. Their incidence is statistically greater in males than in females, with the first symptoms usually appearing between the 4th and 7th decade of life. Aim: The aim of the study was to assess the usefulness of the new classification proposed by European Salivary Gland Society (ESGS) in comparison with the divisions of procedures previously valid in the literature, making a retrospective analysis of patients operated on due to benign tumors of large salivary glands in the Department of Otolaryngology, Head and Neck Oncology of the Medical University of Lodz in 2012–2020. Material and methods: The retrospective examination was based on the material consisting of: surgical protocols, histopathological results, imaging results and clinical observations. The material includes 283 patients (141 women and 142 men): 249 patients with parotid gland tumor and 34 patients with submandibular gland tumor. The most common histopathological diagnosis was pleomorphic adenoma, which was found in 105 patients (42.17%) and adenolymphoma diagnosed in 94 patients (37.75%). Results: The most common type of surgery was superficial parotidectomy including total superficial parotidectomy in 86 patients (34.54%) and partial superficial parotidectomy in 49 cases (19.68%). Then, according to the frequency of surgery, extracapsular tumor dissection (ECD) was performed (91 patients – 36.55%). According to the ESGS classification, in most cases parotidectomy I, II (37.34% of all parotidectomies) and parotidectomy II (28.49%) were performed. In case of ECD, all tumors were located at level II. Conclusions: In summary, the new classification is aimed at unifying, but also simplifying the current nomenclature, reducing the existing nomenclature errors. Determination of the exact location and extent of the tumor within the parotid gland facilitates postoperative monitoring of patients by ENT doctors and those of other specialties.

    Opis:
    Introduction: Warthin’s tumor is a non-malignant tumor that occurs in major salivary glands. Diagnostics include an interview and physical examination as well as additional tests – ultrasonography, magnetic resonance tomography, fine-needle aspiration biopsy. Surgical tumor resection remains the method of treatment, the scope of which includes techniques from extracapsular tumor resection to a full range of parotidectomy. Material and methods: A retrospective analysis was conducted for available medical records of 53 patients treated surgically at the Department of Otolaryngology and Laryngological Oncology at the Collegium Medicum of the Nicolaus Copernicus University in Toruń in 2009–2016. Each patient underwent an interview, physical examination and a routine ultrasound examination. Results of treatment of 57 tumors were analyzed. Results: The study showed that in the case of extracapsular tumor excision in 57 patients in the treatment of Warthin’s tumors of the lower pole of the parotid lobe, there were no complications in the form of: permanent paralysis or facial nerve palsy, mucocele, symptoms of Frey’s syndrome or cosmetic facial defect. Ultrasound examination performed in 8 (14%) patients revealed lesions requiring further diagnostics or periodic ultrasound monitoring. Conclusions: 1. Extracapsular tumor excision appears to be an accurate surgical technique in Warthin’s tumor of the lower pole of the parotid gland’s superficial lobe. 2. After removal of a cancerous lesion of the parotid gland, every patient requires periodic laryngological monitoring.
