      <hc_freetext>Condition 1: Pain in the oropharynx after simultaneous surgery of the two jaws. Condition 2: Pain in the oropharynx after simultaneous surgery of the two jaws.</hc_freetext>
      <i_freetext>Intervention 1: Patients in the intervention group will be irradiated in the oropharyngeal region with 940 laser (Biolase, USA) immediately after surgery and before removal of the nasopharyngeal tube. Irradiation will be done continuously on all regions of oropharyngeal walls i.e posterior wall, lateral walls and posterior of the tongue. Irradiation will be fulfilled with a regular head and without contact to skin or mucosa.  Output power is 100 w and spot size is 0.5  cm2. Irradiation time in each region is 20 s and power density is 0.2 w/ cm2. Intervention 2: Control group: In patients in the control group, after laser surgery of both jaws, no 940 diode laser radiation (Biolase, USA) is performed in the oropharynx.</i_freetext>
