Successful application of antimicrobial photodynamic and photobiomodulation therapies for controlling osteoradionecrosis and xerostomia after laryngeal carcinoma treatment: A case report of full oral rehabilitation.

We present a clinical case where a conservative treatment based on photonics [antimicrobial Photodynamic Therapy (aPDT) associated to Photobiomodulation therapy (PBMT)] of a patient with osteoradionecrosis (ORN) due to radiotherapy treatment of a laryngeal cancer. As a result of this combined treatment the ORN was controlled (e.g. the necrosis, infection and suppuration disappeared). Moreover, the symptoms reported by the patient (pain and xerostomia) also diminished along with the repair of oral mucosa. In future cases this combined therapy (e.g. PBM therapy and the aPDT) will be further examined.
