Summary
Extracapsular dissection (ECD) offers shorter operative times, reduced drainage, and fewer complications like Frey syndrome and temporary facial nerve injury compared to partial superficial parotidectomy (PSP) for benign parotid tumors. Both techniques show comparable safety, with ECD presenting perioperative benefits.
Area of Science:
- Otolaryngology
- Surgical Oncology
- Head and Neck Surgery
Background:
- Benign parotid tumors are common, requiring surgical intervention.
- Choosing between extracapsular dissection (ECD) and partial superficial parotidectomy (PSP) involves balancing oncologic safety with functional and cosmetic outcomes.
- Systematic reviews are crucial for comparing surgical techniques in head and neck oncology.
Purpose of the Study:
- To systematically review and meta-analyze perioperative outcomes and surgical safety of ECD versus PSP for benign parotid tumors.
- To compare operative duration, drainage, hospital stay, and complication rates between the two surgical approaches.
- To assess the oncologic efficacy, including recurrence and complete excision rates, of ECD and PSP.
Main Methods:
- A comprehensive literature search was conducted in PubMed, Embase, and Cochrane Library up to March 2025.
- Fourteen English-language studies directly comparing ECD and PSP for benign parotid tumors were included.
- Random-effects meta-analyses were performed to compare outcomes such as operative duration, drainage volume, hospital stay, Frey syndrome, and facial nerve injury.
Main Results:
- Extracapsular dissection (ECD) was associated with significantly shorter operative duration, lower drainage volume, and shorter hospital stays compared to partial superficial parotidectomy (PSP).
- ECD demonstrated reduced incidences of Frey syndrome and temporary facial nerve (FN) injury.
- No significant differences were observed in tumor size, recurrence rates, permanent FN injury, or complete tumor excision rates between ECD and PSP.
Conclusions:
- Both extracapsular dissection (ECD) and partial superficial parotidectomy (PSP) exhibit comparable surgical safety for benign parotid tumors.
- ECD provides notable perioperative advantages, making it a potentially suitable option for carefully selected patients.
- Further prospective research is recommended to validate these findings and optimize surgical decision-making.
