Caution in the use of TissuePatchDS-P™ in drainless benign superficial parotidectomy, a pilot study: our experience in three patients.

Benign parotid surgery is a common Head & Neck procedure often requiring up to two nights as an inpatient, however fibrin glue products are allowing for drainless parotid surgery. TissuePatchDS-PTM is a synthetic adhesive patch dressing which has been used successfully in skull base surgery and neck dissections to reduce CSF leaks and drainage output. TissuePatchDS-PTM was used in 3 pilot patients undergoing benign superficial parotid surgery as a replacement for surgical drain. All patients were discharged within 24 hours with minimal symptoms and no complication. Within 72 hours all pilot patients developed a sialocoele which was managed with repeated aspirations with no long-term patient harm. It was therefore deemed appropriate to close this pilot study.
