A Pilot Study to Assess the Sialendoscopy-Assisted Transfacial Approach in Parotid Gland Sialolithiasis.

Abstract

Twenty percent of the total lithiasis that affect a major salivary gland will be found in the parotid gland. An exclusive sialoendoscopic approach has achieved success rates close to 80%. In a significant percentage of these remaining cases, combined transfacial approaches assisted by sialendoscopy are presented as an option to be taken into account. A prospective analysis of cases treated by combined transfacial approach assisted by sialendoscopy for lithiasis of the parotid gland and the impact of the facial nerve stimulator used during surgery. Five patients were included; all of them operated satisfactorily. In 4 of them, the approach proposed by McGurk and modified by Capaccio was used, and in 1 of them, the approach proposed by Nahlieli was used. We suffered a complication in just case due to the appearance of postoperative sialocele. According to our results and those previously published, the transfacial approach assisted by sialendoscopy can be considered a useful technique. Proper planning ensures an optimal result in the treatment of parotid gland lithiasis. The use of facial nerve stimulator guarantees extra security when working near to a branch of the facial nerve is suspected.
