The purpose of this study is to determine whether subanesthetic ketamine addition to lidocaine decreases postoperative pain scores in infiltration anesthesia during rhinoplasty.
In rhinoplasty operations local infiltration anesthesia uses for surgery insight and patient comfort. The investigators designed this study to prolonged the time of infiltration block and preventive analgesia. So, before operation, study drugs will infiltrate to the submucosa of intranasal cavity. Then, surgeon and patient satisfaction, postoperative analgesic demand, postoperative pain scores and side effects will determine.

Postoperative pain scores on the Visual Analogue Scale
Pain scores will examine with Visual analogue scale (VAS, 0-100) in the first 24 hours of postoperative period. The examination will repeated in different time period(5.min, 15.min, 30.min, 1 h, 2h,4.h, 6.h, 8.h, 16.h, 24.h). Patients that have VAS\>40 will receive 1mg/kg tramadol.
Time frame: 24 hours
Patient satisfaction
At the end of postoperative 24 h, the patient satisfaction will examine by a score as (1 poor, 2 middle, 3 good, 4 perfect)
Time frame: 24 hour
Analgesic demand
At the first day of postoperative period, analgesic requirement will record. When Visual analogue scale \> 40, intravenous 1 mg/kg tramadol bolus will give.
Time frame: 24 hour
