Summary
Surgical treatment for Frey's syndrome after parotidectomy is explored, reviewing various options. While no definitive gold standard exists, local flaps are increasingly favored over older techniques like tympanic neurectomy.
Area of Science:
- Otolaryngology
- Plastic Surgery
- Surgical Oncology
Background:
- Frey's syndrome, characterized by gustatory sweating, can occur post-parotidectomy.
- Surgical interventions for Frey's syndrome aim to be prophylactic or therapeutic.
- Current treatment strategies lack a universally accepted gold standard.
Purpose of the Study:
- To provide a comprehensive overview of the current state of surgical management for Frey's syndrome.
- To review the indications, benefits, and drawbacks of diverse surgical approaches.
- To analyze the evolution of surgical techniques over time.
Main Methods:
- A scoping review adhering to PRISMA guidelines was performed.
- Searches were conducted across PubMed, Scopus, Cochrane, and Web of Science databases.
- The PICO protocol and specific keywords guided the literature search for Frey's syndrome surgical treatment.
Main Results:
- Fifteen articles met the inclusion criteria for the review.
- Surgical outcomes for gustatory sweating have varied, with no definitive gold standard established.
- A notable shift in surgical trends is observed, moving from tympanic neurectomy to local flap interposition techniques.
Conclusions:
- Surgical intervention is a feasible treatment option for Frey's syndrome.
- Indications for surgery include treatment failure, tumor recurrence, debilitating symptoms, and cosmetic concerns.
- Local flaps represent a more recent and preferred surgical approach.

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
