Effects of Arytenoid Adduction and Type I Thyroplasty Combined Surgery for Unilateral Vocal Cord Paralysis / 대한이비인후과학회지

Type I thyroplasty, we know, could not overcome the large posterior glottal chink and arytenoid adduction have been proved to be uneffective in the cases of unilateral vocal cord paralysis with vocal cord atrophy or bowing deformity. So we performed type I thyroplasty in conjunction with arytenoid adduction and tried to compare the postoperative results with that of arytenoid adduction. We experienced 8 cases of arytenoid adductions and 6 cases of combined operations in the cases of unilateral vocal cord paralysis. All 14 patients had large posterior glottal chink. In order to compare the postoperative voice results of two groups as objective as possible, we performed preoperative and postoperative videoimage analysis(chink size, interarytenoid distance) and computer-assisted voice analysis(MPT, Jitter, Shimmer, S/N ratio). As a results, the postoperative voice outcome is superior with the combined operation than with the arytenoid adduction only in the cases of unilateral vocal cord paralysis with large glottal chink.

Sequential Change of Fibrosing Alveolitis On High-Resolution CT: Correlation with Finding at Pulmonary Function Test and Bronchoalveolar Lavage

PURPOSE: To evaluate prospectively relationship between the extent of abnornelities of fibrosing on high resolution CT and these of pulmonary function test, and bronchoalveolar lavage. MATERIAL AND METHODS: This study included 27 patients with pathologically proved UIP. We prospectivel analyzed correlation of the extent of gound glass opacity, consolidation, irregular lines with honeycombing initial CT scan and quantitative change of ground glass opacity on follow up CT scans with pulmonary function test(PFT) and bronchoalveolar lavage(BAL). RESULTS: On initial CT scan, score of extent of disease significantly correlated with FEV1(r=-0.5148, p=0. 0310) and DLco(r=--0.7102, p=0.0001). Proportion of indivisual cell in BAL was not correlated with ground glass opacity or extent of disease;lymphocyte(p=-0.0165, r=0.9616), eosinophil(p=-0.0077, r=0.9832), neutrophil: (p=-0.1732, r=0.5903). On follow up CT scan, quantitative change of ground glass opacity correlated with DLco/VA(r=-0.6825, p=0. 0025) and TLC(r=0.5248, p=0.0429). CONCLUSION: The quantitative analysis of extent of disease on HRCT is useful for evaluation of clinical statu& Also change of ground glass opacity on follow-up HRCT significantly correlated with improvement of diffusing capacity in fibrosing alveolitis.
