Adenoid cystic carcinoma (ACC) is a rare malignant tumor that might occur in nasal cavity and paranasal sinuses. It is characteristic for poor prognosis, especially the solid histopathological subtype of the tumor. ACC might spread along nerves and fascias and it is usually diagnosed at advanced stage. Computed tomography and magnetic resonance imaging together with fine-needle biopsy are the gold standards in the diagnostic procedure of the cancer. Surgery with adjuvant therapy are the most common methods of treatment. Among the surgical approaches, the functional endonasal sinus surgery seems to be the most appropriate and favorable way of treatment. In the study, the authors present a case of a 62-year-old patient with T4aN0M0 ACC tumor treated endoscopically at the Department of Laryngology and ENT Oncology, WSS No. 5 in Sosnowiec. The authors indicate the usefulness of FESS procedure in the treatment of malignancies of nasal cavity and paranasal sinuses. They also review the recent publications on endonasal versus open approach in similar cases. In conclusions, the authors favor endonasal approach as a mini-invasive method of surgical treatment of ACC of paranasal sinuses that results in satisfactory oncological outcome and high quality of patient’s life.

Implementation of TES, direct subcortical white master stimulation, DTI and fMRI into the management protocol of the surgical treatment of insular tumours resulted in total and subtotal resections in 66% of cases with permanent motor disability in 6.6% of patients. Poor prognosis for independent living after surgery mainly affects patients with WHO grade III or IV.

The FTOZA is a useful technique for removal of tumours expanding superiorly to the middle cranial fossa base without significant compression of the brain. Ability to remove tumours through the described approach decreases as the degree of infiltration of the clivus increases.

A proper selection of the range of the approach to jugular foramen paragangliomas based on their topography and volume reduces perioperative injury without negative consequences for the radicality of the resection.
