A retrospective review of clinical records of 34 cases with polypoid vocal folds who underwent endolaryngeal microsurgery was carried out. The results were followings; 1) The incidence was high in elder age group(mean age : 53.7 years old). 2) Bilateral lesions were much more frequent than unilateral ones(67.6% vs. 32.4%). 3) Nine out of 34 patients had associated local pathologies and nine out of 34 patients had associated systemic pathologies. 4) Smoking appeared to be the most dominant predisposing factor(76.5%). 5) Maximal phonation time was decreased in 10 cases out of 14 cases(71.4%) and phonation quotient was increased in 9 cases out of 14 cases(64.3%). 6) All the cases were treated with sucking technique and the voice quality was improved in 32 cases(94.1%) The average duration for voice improvement was 2.8 months.

Vocal folds injury from vocal abuse is important topics of phonosurgery. Recent advances in diagnostic equipment, phonosurgery and speech analysis equipment have provided a lot of Information about fine movement of the vocal folds. However, predicting the reaction of the vocal folds to phonatory trauma remains difficult. The vocal folds need to withstand great vibratory and shearing stress and anchoring fibers of basement membrane Bone play a role in maintaining structural integrity of histologically different epidermis and superficial layer of lamina propria(cover of vocal folds). The purpose of this study is to demonstrate the changes of anchoring fibers in vocal polyp using transmission electron microscope. Various defects were observed : a irregular thickening of basement membrane, a near absence of normal anchoring fiber, a lot of electron dense material in superficial layer of lamina propria, a destruction of hemidesmosome and many vesicles carrying electron dense material In basal keratinocyte. These observations were suggestive of a hyperactivity of basal keratinocyte of vocal folds epithelium in response to vibratory stress.
