title: Acute Suppurative Parotitis Treatment by Diode Laser Combined with ER:YAG Laser.
abstract: OBJECTIVE
  The diode laser combined with Er:YAG laser is a new treatment modality for acute sialadenitis. A 78-year-old woman with acute suppurative parotitis was treated by traditional probe to the duct orifice with oral antibiotics for 2 weeks. The symptoms and signs did not subside after treatment. The Er:YAG laser was used to reduce severe infection and inflammation and low level laser therapy (LLLT) was applied to relieve pain sensation during incision and drainage. Less scar formation and obstruction was observed after the laser treatments.
  
  
  RESULTS
  Purulent secretions from the Stensen duct was noted after milking the parotid gland. The symptoms and signs were significantly relieved after combined laser treatments. The patient experienced no pain during the course of treatment. No recurrence of the symptoms and signs was noted after 1-year follow-up, and the prognosis was very good.
  
  
  CONCLUSIONS
  The hemostatic properties of the diode laser enable better control of the surgical field and faster healing of the wound lesions. The bactericidal effect of Er:YAG lasers has been proved by many researchers, and has been shown to reduce infection and inflammation for better wound healing. The combined laser therapy of diode and Er:YAG lasers is recommended in treating acute sialadenitis.
