A telescoping surgical probe (20; 30; 50; 60; 70; 80; 100; 170) for treating a tissue region within a nasal cavity of a patient, the probe (20; 30; 50; 60; 70; 80; 100; 170) comprising: an elongate outer shaft having a distal end configured for insertion into a nostril of a nasal cavity of a patient, the outer shaft having a longitudinal axis and lumen therethrough; an elongate inner shaft positioned within the lumen of the outer shaft and translatable relative to the outer shaft; and an end effector (24; 34; 54; 64; 74; 104; 154) coupled to a distal end of the inner shaft, wherein a distal portion of the inner shaft is substantially aligned with the longitudinal axis of the outer shaft and the end effector (24; 34; 54; 64; 74; 104; 154) is positioned a first distance from the distal end of the outer shaft when the surgical probe (20; 30; 50; 60; 70; 80; 100; 170) is in a first configuration during insertion and advancement of the surgical probe (20; 30; 50; 60; 70; 80; 100; 170) into the nasal cavity, wherein the end effector (24; 34; 54; 64; 74; 104; 154) is attached to the distal portion of the inner shaft at an angle relative to a longitudinal axis of the distal portion of the inner shaft, and wherein a translation of the inner shaft relative to the outer shaft configures the end effector (24; 34; 54; 64; 74; 104; 154) longitudinally to a second distance greater than the first distance away from the distal end of the outer shaft and laterally away from the longitudinal axis of the outer shaft when the surgical probe (20; 30; 50; 60; 70; 80; 100; 170) is in a second configuration, wherein the end effector (24; 34; 54; 64; 74; 104; 154) in the second configuration is in lateral contact with a tissue region having at least one posterior nasal nerve and is configured to ablate the at least one posterior nasal nerve. an elongate outer shaft having a distal end configured for insertion into a nostril of a nasal cavity of a patient, the outer shaft having a longitudinal axis and lumen therethrough; an elongate inner shaft positioned within the lumen of the outer shaft and translatable relative to the outer shaft; and an end effector (24; 34; 54; 64; 74; 104; 154) coupled to a distal end of the inner shaft, wherein a distal portion of the inner shaft is substantially aligned with the longitudinal axis of the outer shaft and the end effector (24; 34; 54; 64; 74; 104; 154) is positioned a first distance from the distal end of the outer shaft when the surgical probe (20; 30; 50; 60; 70; 80; 100; 170) is in a first configuration during insertion and advancement of the surgical probe (20; 30; 50; 60; 70; 80; 100; 170) into the nasal cavity, wherein the end effector (24; 34; 54; 64; 74; 104; 154) is attached to the distal portion of the inner shaft at an angle relative to a longitudinal axis of the distal portion of the inner shaft, and wherein a translation of the inner shaft relative to the outer shaft configures the end effector (24; 34; 54; 64; 74; 104; 154) longitudinally to a second distance greater than the first distance away from the distal end of the outer shaft and laterally away from the longitudinal axis of the outer shaft when the surgical probe (20; 30; 50; 60; 70; 80; 100; 170) is in a second configuration, wherein the end effector (24; 34; 54; 64; 74; 104; 154) in the second configuration is in lateral contact with a tissue region having at least one posterior nasal nerve and is configured to ablate the at least one posterior nasal nerve.
