Abstract
The aims of this study were (1) to evaluate the transparotid facial nerve dissection approach (TFND), in which the intraparotid cervicofacial or temporofacial division is identified first through a superficial lobe incision; and (2) to compare extracapsular dissection with a TFND (ECD-TFND) with partial superficial parotidectomy with a retrograde approach (PSP) for benign tumours in the tail of the parotid gland with respect to surgical outcomes. Eighty-nine patients underwent PSP or ECD-TFND for benign tumours in the tail of the parotid gland: 49 were treated surgically with PSP and 40 with ECD-TFND. The mean ( ± standard deviation) surgical time did not differ significantly between the groups: 64 ± 22.4 min for PSP and 59 ± 19.8 min for ECD-TFND (P = 0.302). There was a significant difference in sialocele: 18 (36.7%) patients in the PSP group and four (10%) in the ECD-TFND group (P = 0.002). There was also a significant difference in facial nerve injuries: temporary paralysis was observed in 13 (26.5%) patients in the PSP group and two (5%) in the ECD-TFND group (P = 0.007). It appears that TFND is a viable and safe approach when performing ECD for benign tumours in the tail of the parotid gland. ECD-TFND should be preferred over PSP for benign tumours in the tail of the parotid gland.
