Outcome Measures
Primary Outcomes (1)
Number of cases that don't develop post surgical parotidectomy facial nerve weakness after using preoperative intravital staining of the gland with methylene blue dye.
Twenty cases presented to outpatient clinic in Assiut university hospital with benign or primary malignant parotid gland tumors will be included in the study, clinically evaluated, confirmation of diagnosis will be achieved by CT, MRI, or CT/MRI investigations , ultrasonography and fine-needle aspiration biopsy (FNAB). then Divide the selected cases into two groups randomly; group A for surgeries with MB staining and group B for surgeries without MB staining that serves as control group. type of surgery will be chosen according to CT or MRI data and fine-needle aspiration biopsy (FNAB)then Follow up facial nerve injury manifestations for the included cases for one year for comparison between 2 groups
One year
Study Arms (2)
MB group
ACTIVE COMPARATORMb group will undergo surgeries with methylene blue staining
Control group
NO INTERVENTIONControl group will undergo surgeries without methylene blue staining
Interventions
For MB group, the staining of the glandular tissue will be obtained with 3-4 mL of 1% MB that will be introduced into the gland via the salivary duct several minutes before the surgery.The trans-oral catheterization of the Stensen's duct will be performed and the solution will be injected via intravenous cannula.The glandular tissue will turn dark blue.
Eligibility Criteria
You may qualify if:
- All new cases presented with primary benign or malignant parotid tumors.
You may not qualify if:
- Cases with secondary tumors of the gland
