Summary
Low-dose radiation therapy effectively treated persistent salivary fistulas and recurrent ranulas in two patients. This approach resolved salivary flow issues without causing dry mouth (xerostomia), offering a new treatment option.
Area of Science:
- Otolaryngology
- Radiation Oncology
- Surgical Complications
Background:
- Persistent salivary fistulas and recurrent ranulas can be challenging complications following head and neck surgery.
- Surgical management for these conditions may not always be successful, necessitating alternative therapeutic strategies.
Observation:
- Two patients presented with refractory salivary issues: one with a post-surgical salivary fistula near the parotid gland, and another with a recurrent ranula.
- Both patients had previously undergone surgical interventions without complete resolution.
Findings:
- Low-dose irradiation, with a total dose under 30 Gray (Gy), was administered to both patients.
- Complete resolution of the salivary fistula and ranula was achieved in both cases.
- No patient experienced adverse effects such as dry mouth (xerostomia).
Implications:
- Low-dose radiation therapy presents a viable, non-surgical option for managing persistent salivary fistulas and ranulas.
- This therapeutic modality offers a favorable safety profile, avoiding xerostomia.
- Further investigation into low-dose irradiation for refractory salivary disorders is warranted.
