The Clinical and Surgical Characteristics of Parotid Tumors with Parapharyngeal Space Involvement-A Multicenter Experience of the Polish Salivary Network.

Parotid gland tumors (PGTs) with parapharyngeal space (PPS) involvement have a specific clinical course and they can be a great challenge for surgeons, especially due to more difficult approaches and the risk of serious complications. The aim of this study is to present the characteristics of PGTs with PPS involvement. : Retrospective, multicenter analysis of 1954 primary PGTs from 5 years (2017-2021) was performed.

Rationale for Increasing Oncological Vigilance in Relation to Clinical Findings in Accessory Parotid Gland-Observations Based on 2192 Cases of the Polish Salivary Network Database.

The accessory parotid gland (APG, Vth level) differs in histological structure from main parotid tissue. This gives rise to the hypothesis, mirrored in clinical observations, that the representation of tumours is different than in the rest of the gland. The aim of the study was to analyse the epidemiological and histological differences of parotid tumours located in regions I-V, with particular emphasis on the distinctiveness of region V.

Jejunal and ileocolic free flaps for digestive tract reconstruction following pharyngo-laryngo-oesophagectomy - 30 years of single-centre experience.

Introduction: Hypopharyngeal cancer accounts for 3-5% of all squamous-cell carcinoma (SCC) of the head and neck and has one of the worst prognoses. The aim of the study was to evaluate oncologic and functional treatment outcomes in patients with T3-T4a squamous cell hypopharyngeal and laryngeal cancer.

Material And Methods: Retrospective analysis of the material from one treatment site included 90 patients (81 male, 9 female) who had undergone surgery between 1986 and 2010.

Gender-related incidence, risk factors exposure and survival rates of laryngeal cancers - the 10-years analysis of trends from one institution.

Objectives: The aim of the study was the analysis of the epidemiology of laryngeal cancer over 10 years in relation to known risk factors and to assess the current survival rates in this group of patients.

Methods: The data were retrospectively collected from patients' medical records, then entered in the database using dedicated software and a statistical analysis was performed.

Results: 512 subjects - 443 men (86.

[Adenoid cystic carcinoma of the head and neck--a 10 years experience].

Introduction: Adenoid cystic carcinoma (ACC) was first described in 1853 and 1854 by three french scientists, Robin, Lorain and Laboulbène. ACC is a rare cancer of the head and neck (about 1%) and it comprises from 6% to 10% of all malignant tumors of the salivary glands. 15%–30% of these tumors are located in submandibular gland, 30% occur in small salivary glands (in the palate, tongue, mouth, nose, sinuses, mucous membrane of the cheeks) and about 6% in parotid gland.
