To examine neurosensory changes in the chin following bilateral sagittal split ramus osteotomy (BSSRO) using the heat flux technique.
Twelve healthy adults (C-group) and 23 patients undergoing BSSRO (P-group) were examined. The warm sense threshold (WHF) and cold sense threshold (CHF) in the chin of these patients were measured by the heat flux technique. In the P-group, touch sensation also was measured with a visual analog scale (VAS) and the Semmes-Weinstein monofilament test (SW test).
Both WHF and CHF were significantly larger in the P-group than in the C-group (P = .024). Touch sensation (VAS and SW test) were damaged in some patients of the P-group. However, no correlation was revealed between thermal sensation (WHF and CHF) and touch sensation (VAS and SW test) in the P-group.
These results suggest that the thermal sensation in the chin was damaged after BSSRO. The heat flux technique appears to be one of the useful methods for the examination of neurosensory disturbance in the chin.
采用热通量技术研究双侧矢状劈开下颌支截骨术（BSSRO）后颏部的神经感觉变化。
对12名健康成年人（C组）和23例行BSSRO的患者（P组）进行检查。采用热通量技术测量这些患者颏部的温觉阈值（WHF）和冷觉阈值（CHF）。在P组中，还使用视觉模拟量表（VAS）和Semmes-Weinstein单丝试验（SW试验）测量触觉。
P组的WHF和CHF均显著大于C组（P = .024）。P组部分患者的触觉（VAS和SW试验）受损。然而，P组的热觉（WHF和CHF）与触觉（VAS和SW试验）之间未发现相关性。
这些结果表明，BSSRO后颏部的热觉受损。热通量技术似乎是检查颏部神经感觉障碍的有用方法之一。
