[CO2 laser-microscopy technique in treating tumors near the sella turcica]
1Department of Neurosurgery, Haikou Municipal People's Hospital, Haikou 570208, China.
Objective:
To assess the laser-microscopy technique in dealing with tumors near the sella turcica.
Methods:
Sixteen patients with tumors near the sella turcica who had been treated surgically by laser-microscopy technique from October 1996 to June 1998 in Haikou municipal hospital were analyzed retrospectively.
Results:
In these patients, 11 patients had tumors bodies excised totally, and 5 had tumors bodies excised partially. All of then were followed up for 4 to 30 months. The curative effects were satisfactory. In 9 patients with defect in vision before operation, 6 showed obvious improvement, 2 moderate improvement, and 1 unmarked improvement. In 6 patients with endocrinopathy before operation, 4 returned to normal, and 2 showed improvement. In 4 patients with intracranial hypertension before operation, symptoms were retrieved. Only one patient who had diabetes insipidus after operation, and recovered after medication.
Conclusions:
CO(2) laser-microscopy technique the treatment of tumors near the sella turcica is advantageous: few accidental injuries because of its high-accuracy; less harassment to the hypophysis and subthalamus; less complication; small exposure of operative field; less bleeding and clear operative field; no stimulation of metastasis of carcinoma;and no interference of bioelectric current.
Insights
The CO(2) laser-microscopy technique offers a safe and effective surgical option for tumors near the sella turcica, demonstrating high accuracy and minimal complications. This method leads to satisfactory outcomes, including improved vision and endocrine function in treated patients.
Area of Science:
- Neurosurgery
- Oncology
- Minimally Invasive Surgery
Context:
- Tumors near the sella turcica pose significant surgical challenges due to proximity to critical neurovascular structures.
- Traditional surgical approaches may involve substantial morbidity and complications.
Purpose:
- To evaluate the efficacy and safety of the CO(2) laser-microscopy technique for resecting tumors in the sellar region.
- To assess the impact of this technique on visual, endocrine, and neurological functions post-surgery.
Summary:
- Retrospective analysis of 16 patients with sellar region tumors treated with CO(2) laser-microscopy.
- Achieved complete resection in 11 patients and partial resection in 5.
- Demonstrated significant improvements in vision (6/9), endocrine function (4/6 normalized), and intracranial hypertension symptoms (4/4 resolved).
Impact:
- CO(2) laser-microscopy offers high accuracy, minimizing damage to the pituitary and subthalamus.
- Associated with reduced operative field exposure, bleeding, and complications.
- Presents an advantageous surgical modality for sellar region tumors with favorable patient outcomes.
