Comparing the Efficacy of 3% NaCl With Pressure Dressing and Oral Glycopyrrolate With Pressure Dressing in the Treatment of Parotid Sialocele in Postoperative Oral Squamous Cell Carcinoma Patients: Study Protocol of a Randomized Controlled Trial.

Introduction Parotid sialocele is a common complication following surgery for oral squamous cell carcinoma (OSCC), leading to discomfort and potential complications. Various treatment modalities have been proposed, including 3% NaCl with pressure dressing and oral glycopyrrolate with pressure dressing, yet evidence comparing their efficacy is limited. This randomized controlled trial aims to compare the efficacy of 3% NaCl with pressure dressing and oral glycopyrrolate with pressure dressing in the treatment of parotid sialocele among postoperative OSCC patients undergoing neck dissection. Material and methods Patients diagnosed with OSCC undergoing surgical intervention resulting in parotid sialocele will be randomly assigned to receive either 3% NaCl with pressure dressing or oral glycopyrrolate with pressure dressing. Treatment efficacy will be assessed based on the discharge of any serous collection from the suture line, the length of time required for resolution of salivary sialocele, wound dehiscence, the length of the postoperative stay, the amount of time to resume oral feeds, and the timing of postoperative adjuvant therapy. Results This is an ongoing study protocol, and we are expecting the analysis of the results in 2026. Conclusion This randomized controlled trial will furnish invaluable insights into the comparative efficacy of 3% NaCl with pressure dressing and oral glycopyrrolate with pressure dressing in the treatment of parotid sialocele among postoperative OSCC patients. The findings will inform evidence-based decision-making and optimize treatment strategies for this common complication.
