Pituitary adenoma is a benign tumor that affects the pituitary gland. The pathology of this organ accounts for about 20% of cases. The peculiarity of this disease is that it often passes asymptomatically. Such a pathology is found mostly accidentally. In this case, timely diagnosis is important, because only in the early stages of adenoma can be successfully and fairly quickly cured.
The tumor grows slowly, differs ability to squeeze surrounding tissues. This leads to serious neurological disorders, which can be dangerous for the patient's life. Often ends with a disability or a fatal outcome (in the absence of adequate and timely treatment).
The peculiarities of the therapy of this disease are determined by the type of disease, the nature and size of the neoplasm, the sensitivity to this or that type of effect. Medical therapy, hormone replacement therapy, surgical and radiation treatment are used. Surgical methods of treatment are resorted to if other methods are ineffective. It is rather difficult to remove the adenoma of the pituitary gland, because it is located near important structures of the brain. Also there are difficulties of operative access to the adenoma itself. The conclusion about the expediency of removing the tumor can only be made by a neurosurgeon after a careful study of the patient's history and examination. You also need to get all the necessary characteristics of the tumor.
Modern neurosurgery has various minimally invasive techniques for removing adenoma. In many cases, this makes it possible to avoid traumatizing surrounding tissues. Also, in connection with the possibility to avoid trepanation of the skull, the risk of complications is significantly reduced. Various minimally invasive endoscopic methods are widely used today. In particular, a method is also practiced, such as remote removal of a tumor with the help of a cyberknife.
A characteristic feature is that the operation is performed using transnazal access. In this case, the surgeon introduces the probe through the nasal passage. The process of removal is monitored on the monitor. The advantage of the method is that no incision and dissection of the skull is required. The effectiveness of this method of treatment is 90% for tumors of small size. If the tumor is large, the probability of a successful outcome is dramatically reduced. Thus, there is no doubt about the need for early diagnosis.
Transsphenoidal adenomectomy
By transphenoidal adenomectomy is meant a modern and highly effective method of surgical treatment of adenoma. Its effectiveness is about 84%, which is quite a lot for surgery. The risk of complications is minimized. At the same time, the effectiveness and safety of the procedure can be compared with endoscopic treatment techniques.
It is an invasive technique that allows you to visualize the wound surface, provides a high view. The level of manipulative opportunities is also significantly increasing. This allows you to provide a lower level of trauma, reduce the risk of damage to surrounding tissues. As a result, recovery is much faster, the operation is easier to transfer. Eventually, the number of days spent in a hospital is significantly reduced. The period of incapacity for work is also significantly reduced. The duration of postoperative treatment and preliminary preoperative preparation is drastically reduced.
The disadvantages of this method include the lack of visibility of the operating field in the volume. This deficiency can be leveled by improving the endoscopic equipment. In particular, it is necessary that it provides a voluminous survey of the field being operated.
