Objective:
The retrospective analysis of the surgical procedures in primary parotid and metastatic or adjacent parotid tumors.
Patients And Methods:
Retrospective review of the records of 145 patients operated on for primary, metastatic or adjacent parotid tumors revealed 85 patients with benign tumors, 24 with primary malignant tumors, 19 with squamous skin carcinomas, 12 with skin melanomas, 3 with basocellular carcinomas and 2 with sarcomas of the parotid region. The analysis included the type of parotidectomy, the need for facial nerve sacrifice (FNS), type of neck dissection and soft part reconstruction.
Results:
Superficial parotidectomy was performed in 81% of the benign parotid tumors and 100% of skin melanomas. Total parotidectomy was frequent in malignant parotid tumors (62%), epidermoid skin tumors (64%) and in basocellular/sarcomas of the parotid region (80%). Skin graft or flaps was infrequent in primary malignant tumors (12.5%), and frequent in epidermoid skin tumors (74%), melanomas (58%) and basocellular/sarcomas (100%). FNS was necessary in primary malignant (25%), adjacent epidermoid (37%), melanomas (17%) and basocellular/sarcomas (80%). Details on neck dissections are provided.
Conclusions:
Superficial parotidectomy was an adequate procedure for most benign parotid tumors and for melanoma patients. In primary malignant and adjacent or metastatic skin tumors, total parotidectomy, neck dissection and soft part reconstruction were frequent procedures. FNS and soft part reconstruction should be anticipated more frequently in squamous/basocellular skin tumors or sarcomas adjacent to the parotid gland.
