Notes to Financial Statements [Abstract]
Stock-Based Compensation	Note 2 - Stock-Based Compensation CTBI's compensation expense related to stock option grants was $19 thousand and $24 thousand for the three months ended March 31, 2012 and 2011, respectively.  Restricted stock expense for the first three months of 2012 and 2011 was $157 thousand and $160 thousand, respectively, including $30 thousand in dividends paid for each quarter.  As of March 31, 2012, there was a total of $0.1 million of unrecognized compensation expense related to unvested stock option awards that will be recognized as expense as the awards vest over a weighted average period of 0.6 years and a total of $1.5 million of unrecognized compensation expense related to restricted stock grants that will be recognized as expense as the awards vest over a weighted average period of 1.8 years. There were 331 shares of restricted stock granted during the three months ended March 31, 2012, and 45,542 shares granted during the three months ended March 31, 2011.  The restrictions on the restricted stock will lapse at the end of five years.  However, in the event of a change in control of CTBI or the death of the participant, the restrictions will lapse.  In the event of the disability of the participant, the restrictions will lapse on a pro rata basis (with respect to 20% of the participant's restricted stock for each year since the date of award). The Compensation Committee of the Board of Directors will have discretion to review and revise restrictions applicable to a participant's restricted stock in the event of the participant's retirement.  There were no options granted to purchase shares of CTBI common stock during the three months ended March 31, 2012 or 2011.
