- measure
- 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.
- timeFrame
- One year
- description
- 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
