Purpose: Evaluation of the utility of the free anterolateral thigh flap reconstruction of the defects resulting from radical temporal bone resection in the management of lateral skull base malignancies in a single institution.
Methods: An analysis of 17 en bloc subtotal petrosectomies for removal of malignant tumours was performed. There were 12 squamous cell carcinomas, 4 basal cell carcinomas and 1 adenoid cystic carcinoma.
Objectives: Presentation of radiation-induced lesions in carotid arteries of patients with head and neck squamous cell carcinoma (HNSCC) and the evaluation of the effectiveness of endovascular treatment of symptomatic stenoses.
Materials And Methods: We retrospectively analyzed 26 patients who underwent surgery and subsequently cervical radiotherapy (RT) for HNSCC, focusing on radiation-induced vascular disease in neck arteries-from the latency period to the occurrence of neurological events-and the endovascular treatment of the internal carotid artery (ICA) and/or of common carotid artery (CCA) stenoses. The vascular lesions were diagnosed with Doppler ultrasonography and selective digital angiography.
Osteopetrosis is a heterogeneous group of skeletal disorders. It is a rare genetic disease caused by osteoclast dysfunction, leading to invalid bone desorption and remodeling and an increase in skeletal mass and density. We present the case of a 52-year-old female with osteopetrosis of the temporal bone.

Material And Methods: This prospective, observational study carried out between January and May of 2014 encompassed 24 female patients aged 22-44 years (average - 31 years) diagnosed with PCS. Diagnosis of PCS was established by medical history physical examination, transvaginal Doppler ultrasound examination and confirmed by MRI.
Introduction: The use of closed technique in cholesteatoma treatment carries a significant risk of development of residual disease thus requires a second look operation in a proportion of patients. In those with no residual cholesteatoma the second surgery could be avoided.
The Aim Of The Study: was to evaluate the use of non-echo planar HASTE diffusion-weighted MR imaging in the detection of cholesteatoma in patients after canal wall up surgery due to cholesteatoma.
Introduction: Free fibula flap is widely used in head and neck reconstruction. Imaging studies of the donor site can reveal vascular abnormalities and therefore prevent acute leg ischemia.
Aim: Evaluation of the role of donor site vascular imaging studies for free fibula flap planing.
Objective: Pathology of the external and middle ear is the most frequent reason to prescribe antibiotics and perform surgery in children and young adults. In the majority of cases imaging studies are not performed; the need for imaging comes when complications are suspected or when treatment is not effective. This paper discusses indications for temporal bone imaging studies and presents the most frequent pathological conditions, together with differential diagnosis, clinical symptoms and methods of treatment.

Material And Methods: The study was conducted on 43 patients with laryngeal carcinoma. The levels of Cd, Co, and Ni in carcinoma and healthy control tissues was determined by inductively coupled plasma optical emission spectrometry (ICP - OES) using sequential spectrometer.
Background: The aim of this study was to assess head and neck squamous cell cancer and surrounding tissue in computed tomography contrast enhanced and perfusion studies, and to examine the role of perfusion imaging in depiction of tissue infiltration.
Material/methods: We prospectively evaluated 43 primary malignant head and neck tumors, using standard CT followed by perfusion. Blood flow, blood volume, mean transit time, and permeability values were obtained using regions of interest (ROIs) over lesions and surrounding tissue.
Background: Hereditary hemorrhagic telangiectasia (HHT) is a rare systemic fibrovascular dysplasia also known as Rendu-Osler-Weber disease. Epistaxis is often the first and foremost symptom of the disease and recurrent epistaxis is the main complaint.
Purpose: Evaluation of effectiveness and safety of endovascular treatment of epistaxis in HHT patients.

Computed tomography and magnetic resonance imaging-based techniques of functional imaging are proven to be sensitive and reliable tools for detection and staging of head and neck cancer. These new techniques enable to visualize and differentiate subtle pathologic changes before they become evident on standard cross-sectional images. However, it is their role in evaluating possible recurrence and estimation of treatment response that holds the biggest promise.

Sole anatomic imaging has its drawbacks, as early lesion detection often remains challenging, non-neoplastic processes can mimic malignancies and there are doubts concerning the extent of tumour. The purpose of this study was to perform assessment of head and neck squamous cell cancer and surrounding tissue, in order to examine the relationship between perfusion measurements derived from CT perfusion imaging (CTP) and histologic evaluation of resected tissue.

Their presence reduces overall 5-year survival by 50%. The aim of the study was to evaluate the role of computed tomography perfusion (CTP) for differentiation between metastatic and non-metastatic cervical lymph nodes in patients with squamous cell cancer of hypopharynx and larynx.

Material And Methods: Retrospective analysis of 19 patients with histopathologically confirmed WHO grade II glioma and 2 patients with central neurocytoma was conducted.
The aim of the study was to evaluate and compare various helical CT display modes [virtual endoscopy (VE)] and multiplanar reformations (MPR), conventional flexible tracheobronchoscopy (FT) and intra-operative (IO) findings in patients with tracheal stenosis and to analyze the advantage of MPR and VE in diagnosis and treatment planning and in postoperative follow-up. Thirty-seven patients with tracheal stenosis underwent standard neck and chest CT followed by MPR and VE. Results were correlated with the results of FT and IO findings.

It has been defined as neoplastic proliferation of Langerhans cells that express CD1a and S-100 proteins and have Birbeck granules on the ultrastructural examination. Clinical presentation and behaviour are heterogeneous and can range from a solitary lytic bone lesion with a favourable course to a fatal disseminated leukaemia-like form, with a wide spectrum of intermediate clinical presentations between these two extremes.

Patients with RVD need more intensive treatment, and the prognosis is more severe. The aim of this study was to evaluate the usefulness of the measurement of the coronary sinus in the assessment of RVD in patients with acute PE and to compare it with other indicators of RVD.

Approximately 3% of paragangliomas occur in the head and neck area accounting for about 0,6% of all tumours of this region. Head and neck paragangliomas are divided into two groups: neck tumours (carotid body tumor and vagal paraganglioma) and temporal paragangliomas (jugular bulb tumor and tympanic paraganglioma).

Multi-slice computed tomography has become the main method to diagnose and evaluate the intensity of acute pulmonary embolism (PE). The most common cause of PE is thrombosis of veins of the lower limbs and pelvis. The paper presents various aspects of the use of combined pulmonary artery arteriography and indirect venography performed using multi-slice tomography in relation to other methods imaging the venous system used so far.

The major aim of the review is presenting contemporary diagnostic methods applied in gastric imaging as well as their place in clinical treatment. The authors discuss both conventional and modern methods. Although the method of double contrast barium meal is still the most important in stomach diagnostics, the modern methods such as EUSG, CT and MRI are becoming more and more meaningful not only in evaluating gastric neoplastic pathological changes.

Pulmonary embolism (PE) is a common and still difficult clinical problem. On autopsy, PE is diagnosed in 15-25% of hospital deaths, intravitally the diagnosis is reached in only 1/3 of cases. An early diagnosis and antithrombotic treatment decreases the mortality rate from 30 to 2-10%.
