Introduction. The incidence of head and neck cancers in Poland demonstrated a general tendency to stabilize in the last two decades. However, a global phenomenon in the change of morbidity structure in terms of the specific anatomical location is observed, which will probably increasingly apply also to Poland. Aim. The aim of the study was to present the changes that have occurred in the structure of the incidence of oropharyngeal cancer in comparison to laryngeal cancer in the period from 1980 to 2013, in the region of south-eastern Poland and the whole country. Material and methods. A retrospective analysis of the incidence due to the head and neck organ cancer in 1980-2013 in the region of south-eastern Poland and the whole country was performed based on demographic data from the Provincial Statistical Office in Rzeszow and Podkarpackie Cancer Register as well as the Department of Epidemiology, Oncology Centre in Warsaw. Results and conclusion. In the last three decades, the percentage of laryngeal cancer incidence in women (13% vs 18%) as well as oropharyngeal cancer (18.2 % vs 21.6%) was lower in Podkarpacie than in Poland overall. The incidence of oropharyngeal cancer in men in Podkarpacie was lower in the analyzed period than in Poland overall, and only in the last 3 years of observation has it reached a value close to the average for the country. The incidence of laryngeal cancer in men showed a dramatic downward trend both in Poland and in the Podkarpacie province, whereby both in terms of incidence rates and standardized rates and percentages – it is far more pronounced in the analyzed province.
Surgical voice rehabilitation performed by means of voice prosthesis post laryngectomy

Introduction. In 1972, in Poland, Professor Erwin Mozolewski presented a pioneering thesis concerning the creation of intubated voice fistula in a group of 24 patients. It was undoubtedly the prototype of today’s voice prosthesis. Materials and method. The study involved 33 men after total laryngectomy due to advanced squamous cell carcinoma, treated in the Otolaryngology Ward of the District Hospital in Skarżysko-Kamienna between the years 2012–2017, who were implanted with a voice prosthesis Provox II and Provox Vega. Results. During the analyzed period, 127 voice prosthesis were replaced in 33 patients. This paper focuses on complications connected with the implantation of voice prosthesis. The most common reason for replacement of a voice prosthesis was fluid leakage through the voice prosthesis channel – 95 cases. Spontaneous prolapse of the voice prosthesis occurred in 11 patients, and after re-insertion of the prosthesis, the correct fistula voice was obtained. The voice prosthesis was replaced due to difficulty in creating the prosthetic speech in 8 patients. A much more serious complication is the occurrence of leakage around the voice prosthesis. In the examined group, leakage around the prosthesis occurred in 5 patients. An inflammatory plaque was formed around the prosthesis, which was removed in case of significant prosthetic cover or at the request of an alarmed patient – in 4 patients. The prosthesis protruded and rotated in the trachea and hung on a fragment of mucous membrane of the trachea in 1 patient.
