Summary
Function-preserving surgery for benign parotid tumors offers better cosmetic results and fewer complications than conventional methods. This approach enhances facial contour, nerve recovery, and patient satisfaction while reducing surgery time.
Area of Science:
- Otolaryngology
- Surgical Oncology
- Plastic Surgery
Background:
- Parotid tumor treatment has evolved from extensive resections to less invasive partial parotidectomy.
- Evaluating the efficacy of contemporary surgical techniques for benign parotid tumors is crucial.
Purpose of the Study:
- To compare functional outcomes between conventional and function-preserving surgical techniques for benign parotid tumors.
- To assess cosmetic results, nerve function, and complication rates.
Main Methods:
- A randomized controlled trial involving 101 patients with benign parotid tumors.
- Patients were allocated to either conventional surgery (49) or function-preserving surgery (52).
- Function-preserving surgery included modified facelift incision, greater auricular nerve preservation, partial parotidectomy, and parotid fascia coverage.
Main Results:
- Function-preserving surgery resulted in shorter operation times and significantly lower complication rates.
- Higher patient satisfaction with scars and facial contours was observed in the function-preserving group.
- Transient facial paralysis and Frey's syndrome were infrequent (12% and 6%), with high auricular nerve sensory recovery. Salivary flow reduction was less pronounced (71.9%) compared to conventional surgery (20.7%). No tumor recurrence was noted in either group over a mean follow-up of 48 months.
Conclusions:
- Function-preserving surgery for benign parotid tumors yields superior cosmetic, sensory, and salivary functional outcomes.
- This approach reduces surgery duration and operative morbidity compared to conventional procedures.
- Enhanced patient satisfaction and preservation of facial nerve function are key benefits.
