Opis:
Transfacial surgery with the use of microscopic end endoscopic techniques has been used for resection malignant tumors of the paranasal sinuses and anterior skuli base. After tumor resection the dura mater injuries should be carefully closed to avoid the most common postoperative complications (encephalocele, meningocele, meningitis, intracranial abscess and pneumo-encephalus). Authors analyzed cases of tumors of nasal cavity and paranasal sinuses with extension to anterior scull base treated in ENT Department of Medical University of Warsaw. In case of smali injuries to 10 mm in diameter the reconstruction was usually performed with multi-layer technique. In cases of bigger defects the dural piane was rebuild with fascia lata flap by suturing it to the dura mater. Authors conclude that malignant tumors of the paranasal sinuses and anterior skul) base can be resected entirely, together with dura mater by the extracranial approach through a lateral rhinotomy incision.

Opis:
Maxillofacial tumors are rare malignancies that constitute about 0.2–0.5% of all human malignancies. The initial symptoms of the disease are non-typical and imitate inflammation of paranasal sinuses. Most often, patients report one-sided nasal obstruction with bloody and purulent discharge and headaches. In addition to physical examination – often with the use of endoscopic nasal cavity assessment, it is necessary to perform computed tomography of the paranasal sinuses and magnetic resonance for accurate assessment of the extent of the lesions. Histopathological examination of tumor specimens is necessary for making the final diagnosis and planning treatment. Squamous cell carcinoma is the most common histological type in the sinonasal region. Other common malignancies in this area include adenocarcinoma, carcinoma adenoides cysticum, lymphomas, melanoma, and olfactory neuroblastoma. The treatment of choice of all malignant changes in the sinonasal complex, except for lymphomas, is surgical treatment. Unfortunately, a still high percentage of lesions is diagnosed at an advanced stage of the disease, when the infiltration includes the skull base. In these cases, the decision to perform a radical surgical treatment in the patient is very difficult and requires a lot of experience in the surgery of the skull base. However, due to the low radiosensitivity and low effectiveness of chemotherapy in sinonasal malignancy, resection of lesions and complementary treatment contribute to the prolongation of overall survival in this group of patients. The article discusses the cases of two patients with advanced cancer of the sinonasal complex reffered to the Otolaryngology Department of the Medical University of Warsaw.

Opis:
Introduction: Proliferative-inflammatory pathologies may occupy the temporal bone, resulting in: hearing loss, vestibular dysfunction, and neuropathies from cranial nerve compression. Although their occurrence is episodic, the appropriate diagnostic procedure is extremely important to achieve expected therapeutic effect. Aim: The aim of study was characterization of selected proliferative-inflammatory pathologies that may occupy the temporal bone: fibrous dysplasia, inflammatory pseudotumor, osteoradionecrosis, and presentation of diagnostic methods for the differentiation of these diseases as well as discussion on appropriate therapeutic options. Fibrous dysplasia (FD) is a slowly progressive, benign bone disorder of unknown etiology characterized by abnormal proliferation of fibrous tissue. Inflammatory pseudotumor (IPT) is a rare, non-malignant inflammatory process of unknown etiology, characterized by connective tissue proliferation and infiltration of inflammatory cells. Osteoradionecrosis of the temporal bone (TB-ORN) is a rare but potentially fatal complication of radiotherapy for head and neck cancer. Results: Due to the similarity of symptoms with typical inflammatory conditions of middle ear (pain, otorrhea, hearing loss), selected disorders may be a dilemma regarding the diagnosis and proper further treatment. The clinical examination is mandatory, however radiological imaging may demonstrate the presence of specific changes and direct the diagnosis. The computed tomography (CT) of fibrous dysplasia shows the abnormal organization of the bone structure. Magnetic resonance (MRI), as the most sensitive for inflammatory pseudotumors, visualizes inflammatory infiltration in soft tissues. The CT of temporal bone identifies the erosion in the course of osteoradionecrosis. However in all cases the final diagnosis may be establish using histopathological examination and after exclusion of the neoplastic process.
