Background:
Enucleation has been reported as a minimally invasive surgery for Warthin's tumor (WT). However, the definite indications for enucleation have not been clarified.
Methods:
Enucleation was indicated by the following findings: findings of WT, cystic fluid, or benign leukocytes by fine-needle aspiration cytology; a well-margined and homogeneous pattern on imaging; and a tumor location in the tail or preauricular area of the parotid gland. We reviewed 552 cases treated with parotid gland surgery in our hospital.
Results:
A total of 108 tumors were treated with enucleation and included no malignant solid tumors or pleomorphic adenoma. Enucleation demonstrated low invasiveness and complication rates. Revision surgery for WT reappearance after enucleation was rare and showed minimal scarring, with a lower risk of facial weakness.
Conclusions:
The indication criteria for enucleation were validated. Such enucleation is useful, as it is associated with minimal invasiveness, low complication rates, and safety in revision surgery.
