Predictive factors for post-operative drainage after partial superficial parotidectomy: a case-control study

Area of Science:

• Surgical Oncology
• Otolaryngology

Background:

• Post-operative drainage is a common concern following parotidectomy.
• Identifying factors influencing drainage is crucial for patient management.

Purpose of the Study:

• To investigate post-operative drainage patterns after partial superficial parotidectomy.
• To evaluate the impact of a bipolar vessel-sealing device on drainage and operative time.

Main Methods:

• Retrospective analysis of 49 patients undergoing parotidectomy.
• Comparison of drainage in patients with and without bipolar vessel-sealing device use.
• Analysis of predictive factors including body weight, diabetes, and operative time.

Main Results:

• Increased post-operative drainage was associated with higher body weight and non-use of the bipolar vessel-sealing device.
• A trend towards increased drainage was observed in diabetic patients.
• Bipolar vessel-sealing device use significantly reduced operating times.

Conclusions:

• Obesity and diabetes increase the risk of prolonged post-operative drainage.
• The bipolar vessel-sealing device is effective in reducing drainage and operative time.
• Extended drain placement may be necessary for obese and diabetic patients.
