Salivary Gland Tumor- Epidemiology, Treatment Modalities And The Predictability Of Using Cryotherapy Model As Implemented In Breast Tissue Tumors

Objectives: Salivary glands tumors account for 3% of head and neck tumors.
The purpose of this study was to examine the option of using cryosurgery as a treatment for salivary gland tumors. Cryosurgery is already in use for treatment of breast benign tumors and is considered a minimal invasive procedure, has short treatment time, require local anesthesia, no need for an operational room, no hospitalization, minimal scarring and good nerve regeneration potential.
objectives :
1. To identify suitable tumor(s) to be treated by cryosurgery, based on the breast model.
2. To determine whether size of tumors at time of diagnosis comply with the cryosurgery probe size (0.35-3cm)
3. To assess the reliability of the FNA (Fine Needle Aspiration) test compared with final diagnosis
Methods: We reviewed all records of patients diagnosed with salivary gland tumors, treated in the departments of OMS / ENT at the Hadassah Medical center between the years 2000-2012. Variables included demographic details, complaints and clinical presentations at admission, tumor diagnosis by FNA and by final diagnosis (pathological evaluation of excised tumor), size of tumor, treatment and hospitalization details and recurrences.
Results: Pleomorphic Adenoma accounted for 55.1% of tumors. Among the PA cases, 93% were palpable at time of diagnosis, 91% showed obvious swollenness and 84.4% were within the cryosurgery potent diameter. There was 99.3% positive correlation between FNA diagnosis and pathological results. Treatment included 91% surgical excisions, with an average of 6.9 hospitalization days
Conclusions: Our findings suggest that PA of major salivary glands may be regarded as a suitable candidate for the cryosurgery approach. Reliability of FNA tests was high, suggesting we can prevent patients from going through general anesthesia and excisional surgery, risk of nerve damages and decrease hospitalization days
