Extracapsular dissection of pleomorphic adenoma in the parotid gland: A case report and review of the literature

Abstract

Salivary gland tumors comprise of less than 3% of all tumors of the head and neck region. Pleomorphic adenoma represents 45 to 74% of all these salivary gland tumors and 65% of them occur in the parotid gland. Owing to the close proximity of this tumor to the facial nerve, there have been various techniques for surgical management of this tumor in the literature. Extracapsular dissection of pleomorphic adenoma is a conservative treatment modality which spares the handling of facial nerve. We are reporting a case of extracapsular dissection of pleomorphic adenoma in the lower pole of the superficial lobe of the parotid gland in a 22 year-old Indian male with a 1-year follow-up.

The outcome and decision‐making of extracapsular dissection for benign superficial lobe parotid tumours: Our experience in 144 patients

“…The decreased transient facial paralysis rate in the ECD group may be due to the minimal exposure of facial nerve. 4 Our results were compatible with previous studies.…”

“…The ECD group had less transient facial paralysis rate than the SP group (0% vs 15%, P < .001) with similar permanent facial paralysis rate (0% vs 1%, P > .99) and tumour recurrence rate (2% vs 2%, P > .99). The decreased transient facial paralysis rate in the ECD group may be due to the minimal exposure of facial nerve . Our results were compatible with previous studies.…”

“…3 The extracapsular dissection (ECD) was first described by Gleave on 1979 and was adapted gradually by the experienced surgeons. 4 It included the dissection of the parotid tumour with a 3-to 4-mm surrounding tissue outside the capsule as margin, leaving the capsule intact to prevent the residual tumour and the tumour seeding. 4 During the technique of ECD, the nerve dissection was avoided and the risk of nerve injury during nerve dissection was prevented.…”
