Reconstruction of head and neck defects after surgery for cancer remains challenging. The choice of the reconstruction technique  depends on the tumor size and localization, type of the defect,  patient’s age, concomitant diseases, and disease prognosis.  Surgeons have currently a broad range of material for reconstructive surgery, from free flaps to revascularized flaps. Microsurgical  reconstruction has made a revolution in treatment of patients with  complex head and neck defects. However, the use of this technique may not be advisable for some patients. The search for  new techniques is needed to improve functional and aesthetic results and reduce traumatism without compromising oncologic outcomes.  Thirty-six patients underwent surgery with reconstruction using the  submental island flap, a new alternative in the reconstruction of  various head and neck defects. The graft was taken after making a  neck incision for neck lymph node dissection. A few patients develop  total and marginal necrosis of the graft. Short- and long-term results showed no worsening of oncologic outcomes in the selected group of patients.

Introduction. The increasing incidence of oropharyngeal squamous cell carcinoma observed globally in recent decades gave rise to research in this area. In 2005, human papillomavirus was proved to be an etiological factor of oropharyngeal squamous cell carcinoma. Currently, oropharyngeal squamous cell carcinoma associated with human papillomavirus is believed to have some unique characteristics. The analysis of oropharyngeal squamous cell carcinoma epidemiology appears to be highly relevant.Objective – to assess the incidence and prevalence of oropharyngeal squamous cell carcinoma associated with human papillomavirus in Russia on the example of a certain sample of patients.Materials and methods. We analyzed medical records of 199 oropharyngeal squamous cell carcinoma patients treated in N. N. Blokhin Russian Cancer Research Center between 2016 and 2021. We analyzed the frequency of tumors associated with human papillomavirus, age, sex, tumor spread and stage depending on р16 status.Results. More than half of the patients from our cohort (58.3 %) were р16‑positive. The peak incidence was observed in individuals aged 45 to 64 years (more than 60 % of cases). Males were twice as likely to have р16‑positive tumors than females. A total of 60.9 % of patients with р16‑positive tumors had stage I disease, whereas 51.2 % of patients with p16‑negative tumors had stage IV disease.Conclusion. The results obtained for a sample of Russian patients are comparable with the findings of foreign authors.

Introduction. Lymphomas are a heterogenic group of tumors of the lymphatic and hematopoietic systems, and in many cases tumor process develops in the area of the head and neck including skin and mucosa, orbit, nasal cavity and paranasal sinuses, oral cavity, oropharynx, salivary glands, thyroid, and cervical lymph nodes. Differential diagnosis of lymphomas of the head and neck is complicated because it can be accompanied by another non-tumor pathology. High heterogeneity of lymphomas of the head and neck requires structurization of knowledge on their epidemiological and clinical manifestations.The study objective is to optimize early diagnosis as it allows to significantly increase cancer alertness in local practitioners, oncologists, diagnosis specialists and, in turn, to decrease verification frequency in generalized disease processes. Study of clinical characteristics of lymphoproliferative disorders of the head and neck leads to increased quality of differential diagnosis.Materials and methods. A study of lymphoproliferative disorders affecting head and neck was performed. Study material consisted of data on 174 patients hospitalized at the N.N. Blokhin National medical Research Center of Oncology between 1999 and 2020.Results. Based on the current clinical and morphological classification of lymphoproliferative disorders, data on location of lesions, characteristic signs of extranodal lesions and cervical lymph nodes involvement, as well as methods of diagnosis of lymphomas of the head and neck, are presented.Conclusion. The obtained data helps solve problems of diagnosis of lymphoproliferative disorders affecting the head and neck and serve as a basis for successful, predictable treatment of lymphomas.
