[Treatment of vocal cord submucosal bleeding with pricking therapy].

Objective: To observe the clinical efficacy of pricking bleeding of 3 points of the thumb tip, and 3 points of the auricular helix for treatment of vocal cord submucosal bleeding (VCSB), so as to provide a better therapy for it.

Methods: Sixty VCSB patients were equally randomized into pricking bleeding group and ultrasonic atomizing inhalation (UAI) group. Pricking bleeding was applied to Shaoshang (LU 11, 0. 1 cun to the nail on the radial side), Zhongshang (the center of the thumb back, 0. 1 cun to the nail), Laoshang (0. 1 cun to the nail on the ulnar side), Lun 1, 3 and 5 (MA-H) of the helix, once daily for 7 days. Ultrasonic atomizing inhalation treatment was given to patients of the UAI group for 15 min every time, once daily for 7 days. The scores of symptoms and signs and their difference values were calculated before and after the treatment. The acoustical parameters maximum phonation time (MPT), frequency perturbation quotient (FPQ), amplitude perturbation quotient (APQ), ratio of harmonic to noise (H/N) were detected by using a USSA Computer Language Phonetic Spectrum Analysis System.

Results: Of the two 30 cases of VCSB patients in the pricking bleeding and UAI groups, 20 (66.67%) and 12(40.00%)were cured, 7 (23.33%) and 6 (20.00%) were improved remarkably, 3 (10.00%) and 8 (26.67%) improved, and 0 and 4 (13.33%) failed, with the cure plus markedly effective rates being 90% and 60%, respectively. The cure plus markedly effective rate of the pricking bleeding group was significantly superior to that of the UAI group (P<0. 01). The difference values between pre-treatment and post-treatment in hoarseness, laryngalgia, throat dryness, throat burning sensation, throat clearing, vocal bleeding, glottis dysraphism, and total score were significantly higher in the pricking bleeding group than those in the UAI group (P<0.05). In comparison with the pre-treatment, MPT and H/N values were increased obviously (P<0. 05), and FPQ and APQ decreased clearly in the two groups after the treatment (P<0.05), suggesting an improvement of the acoustical parameters after the treatment. But, no significant differences were found between the two groups (P>0. 05).

Conclusion: Pricking bleeding therapy is effective in relieving submucosal bleeding of the vocal cord and can improve its clinical symptoms and signs.
