Parotid fistula and tympanic neurectomy

Area of Science:

• Otolaryngology
• Surgical Innovation

Background:

• Parotid fistulas are typically posttraumatic, with spontaneous closure being the usual outcome.
• Conservative management includes bowel rest, pressure dressings, and intravenous nutrition; anticholinergic drugs may reduce salivary output.

Observation:

• Non-healing parotid fistulas necessitate more aggressive interventions.
• Treatment strategies vary based on whether the fistula is ductal or glandular.

Findings:

• Tympanic neurectomy is presented as a satisfactory treatment for selected parotid duct fistulas and the preferred method for glandular fistulas.
• Low-dose radiotherapy and surgical excision with duct ligation have also been described but showed limited success in some cases.

Implications:

• Tympanic neurectomy offers a viable therapeutic option for refractory parotid fistulas.
• The suppression of parasympathetic activity, even if transient, is sufficient to facilitate fistula healing and symptom resolution.
