Objective:To evaluate the curative efficiency on vocal function of 56 laryngeal palsy patients underwent arytenoid adduction operationMethod:Voice analysis and laryngeal aerodynamical measurement were performed for the 56 laryngeal palsy patients to compare maximum phonation time(MPT),mean flow rate (MFR),voice intensity(SPL), and expiratory pressure(EP)before and after operation.Perceptual evaluation was also performed for comparison by using GRBAS system(G).Result:The postoperative average MPT increased by 3.1 times in males and 2.7 times in females.The average MFR decreased apparently from 827.3 ml/s in males and 477.1 ml/s in females before operation to 340.3 ml/s and 158 ml/s after operation,which was statistically significant(P＜0.01).The average SPL increased and the average EP decreased after operation.After operation the average G decreased from 2.8 to1.7 (P＜0.01) and the percentage of improvement over one grade was 71%.Conclusion:From these results mentioned above,it can be concluded that the arytenoid adduction operation might be one of the most effective operative methods to improve glottal incompetence caused by laryngeal nerve paralysis.

In dentistry, it is empirically known that the acute exacerbation of periodontal disease often occurs at the time of fatigue, but scientific verification has never been made about the relationship of fatigue and bleeding. In Kampo medicine, there is the concept of spleen failing to control the blood as bleeding at the time of fatigue. Kihito and kamikihito are often used for this condition. Spleen failing to control the blood means that lack of vital energy causes the bleeding. Kamikihito is most often used in the treatment of idiopathic thrombocytopenic purpura. Moreover, there have been some reports on the use of kamikihito in the treatment of gynecological fraud bleeding and aplastic anemia. However, there has been no report on the use of it in the treatment of gingival bleeding. In this case, neither cytopenia nor obvious coagulopathy was recognized. In Kampo medicine, not only spleen failing to control the blood but also blood stasis or blood heat is considered to be the cause of bleeding, but the effectiveness of kamikihito for this case suggested pathophysiology of spleen failing to control the blood. Kamikihito could be a choice to treat gingival bleeding at the time of fatigue.
