A septoplasty instrument includes at least one shaft having an end effector at a distal end thereof. The end effector includes first and second electrode members, each having an electrode disposed within an insulative housing. At least one of the housings includes a lumen configured to circulate a cooling fluid therethrough. The lumen extends the length of the electrode member along an outer periphery thereof. At least one of the electrodes is adapted to conduct energy through tissue disposed therebetween. The electrode members are positionable on either side of the nasal septum. Upon application of energy to the electrode(s), energy is conduced between the electrodes and through the nasal septum such that the nasal septum is heated above about 50° C. and up to about 57° C. to allow reformation thereof, while the cooling fluid is circulated within the lumen to maintain tissue surrounding the electrode in a cooled state.
