  • Background and Objectives : This study aimed to evaluate patients' subjective and objective outcomes after laryngeal microsurgery for benign vocal fold (VF) lesions, and to identify usefulness of surgical treatment. Materials and Methods : The authors reviewed the 102 patients medical records, retrospectively who received laryngeal microsurgery for benign VF lesions from January 2013 to August 2017. Subjective voice were measured using the Voice Handicap Index (VHI). Objective voice were recorded with Multi-Dimensional Voice Program (MDVP) just before surgery, and after at least 3 months of surgery. Results : Benign VF lesions were categorized as VF nodule (n=34, 33%), VF Polyp (n=47, 26%), Intracordal cyst (n=15, 15%), Reinke's edema (n=6, 6%), and VF Papilloma (n=2, 2%). Post-operative voice assessment at VHI scores showed statistically significant reductions in all of functional, physical and emotional parts (p<0.001). MDVP were showed significant improvement of Jitter (P=0.001), Shimmer (p<0.001) and Noise to Harmonic Ratio (NHR) (p=0.001). Conclusion : Laryngeal microsurgery for benign vocal fold lesions is effective treatment with statistically significant improvement at subjective and objective vocal quality assessment.

  • The purpose of this study was to evaluate the efficacy of a multiple voice therapy technique ($SKMVTT^{(R)}$) using laughter for the treatment of various benign vocal fold lesions. To achieve this, 23 female patients diagnosed with vocal nodules, vocal polyp, and muscle tension dysphonia through videostroboscopy were enrolled in vocal hygiene and $SKMVTT^{(R)}$. All of the patients were treated once a week for 4 to 12 sessions. The GRBAS scale was used to confirm the changes in voice quality before and after the treatment. Acoustic analysis was performed to evaluate jitter, shimmer, NHR, fundamental frequency variation, amplitude variation, PFR, and dB range. Videostroboscopy was performed to confirm the changes in the laryngeal features before and after the treatment. After the $SKMVTT^{(R)}$, the results of the perceptual evaluation demonstrated that the G, R, and B scales significantly improved. An acoustic evaluation also demonstrated that jitter, shimmer, NHR, vAm, vFo, PFR, and dB range also significantly improved after the $SKMVTT^{(R)}$. In comparison to the videostroboscopic findings, the size of the vocal nodules and vocal polyp decreased or disappeared after the treatment. In addition, the size of the cuneiform tubercles decreased, the length of the aryepiglottic folds became longer, and the laryngeal findings of the supraglottic compressions improved after the $SKMVTT^{(R)}$. These results suggest that the $SKMVTT^{(R)}$ is effective in improving the vocal quality of patients with benign vocal fold lesions. In conclusion, it seems that laughter and inspiratory phonation suppressed abnormal laryngeal elevation and lowered laryngeal height, which seems to have the effect of improving hyperfunctional phonation.

  • The pulsed photoangiolytic 532-nm potassium-titanyl-phosphate (KTP) laser has emerged in recent years as an efficacious treatment modality for vocal fold lesions. It also has broadened the indications for other laryngeal laser surgery. Features of KTP laser that it is a fiber-based delivery system and its energy is selectively absorbed by oxyhemoglobin make it suitable for office-based laryngeal procedures. An office-based KTP laser surgery provides an alternative management option for benign laryngeal diseases and can be performed comfortably under flexible endoscopic guidance which is placed through the nose of a fully awake patient. Office-based laryngeal surgery with a KTP laser can alleviate the need for general anesthesia. However, there are some limitations to apply due to reduced visual precision and the fact that the vocal folds are moving during procedures. Clinicians should carefully weigh the advantages and disadvantages of office-based procedures before a treatment option is selected. Patient selection and standardized laser energy parameters may help in decreasing complications and improving the treatment results.

  • Benign vocal fold lesions, such as vocal nodules, polyps and Reinke's edema, usually result from chronic voice overuse. Conservative management such as voice therapy and pharmacotherapy are used as the primary treatment techniques. The main purpose of voice therapy is to identify and reduce voice misuse to achieve the optimal voice. But complete resolution may not be possible in all patients after voice therapy. Furthermore, some patients with voice-related occupations, voice rest and voice therapy are sometimes difficult, which makes it hard to carry out the treatment. When conservative therapy is ineffective, laryngeal microsurgery can be performed under general anesthesia. However, potential complications following laryngeal suspension and violation of the layered structure of the vocal fold during surgery should be considered before surgery. In recent decades, emerging literatures have demonstrated the potential usefulness of vocal fold steroid injection as an alternative treatment option for benign vocal fold lesions. The most advantageous feature of vocal fold steroid injection is the maintenance of regional anti-inflammatory effects while preventing the potential systemic adverse effects of the steroid. Many non-surgical treatment methods can be conducted using different approaches in the office setting. It can be applied as an alternative treatment modality for the management of various benign vocal fold lesions.

  • Background and Objectives:The Voice Handicap Index (VHI) evaluates the patients perception of impact of voice disorder in term of functional, physical, emotional factors. The purpose of this study was to evaluate the change of patient's subjective voice handicap index before and after laryngeal microsurgery for benign vocal cord lesions. Materials and Methods:We analyzed 55 patients who received laryngeal microsurgery for benign vocal cord disease from January 2011 to February 2013 retrospectively. There were 50 vocal nodules, 3 vocal polyps, 2 vocal cysts. VHI were analyzed before surgery and 3 months after surgery. Results:The VHI scores showed statistically significant reductions postoperatively in functional and emotional VHI (p=0.01 and p=0.034). Also, Emotional VHI score after microsurgery was higher in female than male [adjusted odd ratio (AOR)=0.292 ; 95% confidence interval, CI=0.098-0.869, p=0.01]. Conclusion:In other words, males experience significant more emotional effects that are improved after microscopic surgery.

  • Transoral $CO_2$ laser microsurgery has been widely used for various laryngeal diseases. Laser cordectomy for the management of early laryngeal carcinoma has advantages with regards to oncologic results, preservation of laryngeal functions, morbidity and cost in comparison to those of open surgery or radiation therapy. $CO_2$ laser is also applicable to benign vocal fold lesions such as nodules, polyps, cysts, reinke's edema, granulomas, papillomas, hemangiomas and glottis webs. $CO_2$ laser is suitable for microsurgery because it has small focus size and hemostatic effect. We should also recognize the risks of $CO_2$ laser for safe use.

  • Recently, conservative and bloodless operative procedures have been focused, so that endoscopic laser have been used. However application of endoscopic laser surgery for laryngeal lesion is capable for followings: (1)capability of delivery through an operating microscope, (2) vaporization of ultraspot. $CO_2$ laser which has been used, has limitations for voice improvement because of 700 micron beam spot. KTP-532 laser which is capable of delivery through an operating microscope vapore 200 micron ultraspot has developed and applied to microlaryngeal surgery. We have experienced 60 cases who were contracted with hoarseness(53 cases of benign lesions vocal nodule 13, vocal polyp 13, bilateral diffuse polyposis of vocal cords 11, intracordal cyst 8, vocal papilloma 5, laryngocele 1, laryngeal stenosis 2 and 7 cases of malignant lesions : laryngeal carcinoma stage I and II) since 1991. We operated them with KTP-532 Laserscope(3 Watt/0.05 sec., pulsed or continuous. San Jose, Calif, USA). Forty eigh cases(90.6%) of 53 bengin laryngeal lesions and 4 cases(57.1%) of malignant lesions were significantly improved in their voices. There were a few complications and technical problems, but laser surgery alone had a limitation to eradicate the disease.

  • Papillary cystadenoma is a rare, benign salivary gland neoplasm containing cystic cavities with intraluminal papillary projections. In the head and neck area, it occurs mainly in major and intraoral minor salivary glands, but rarely in the larynx. We report a case of a 67-year-old female with a chief complaint of hoarse voice diagnosed as laryngeal papillary cystadenoma. This paper emphasizes the need to consider papillary cystadenoma as one of differential diagnosis when benign looking lesions are observed in the larynx, where it uncommonly occurs.

  • Examination of the vibrations of the vocal fold is very important in patients with voice changes. The newly developed videokymography (VKG) takes images in real time and records irregular vibrations of the vocal fold. However, there are few data on VKG findings. We studied VKG to evaluate the vibratory characteristics of the vocal fold in benign vocal fold lesions. Unique vibratory patterns, blurred demarcation of the mucosal propagation, decreased margin amplitudes, asymmetry in phase or amplitude, and a level difference of the contact site were observed in each benign vocal-fold lesion. We conclude that each type of laryngeal lesion has specific characteristic which are revealed by VKG examination, these parameters can be quantified and used to objectively evaluate VKG findings. Based on these results, VKG can be used as a supplementary diagnostic tool.

  • Xanthoma disseminatum (XD) is a benign, non-Langerhans cell histiocytosis characterized by disseminated xanthomatous lesions with face, flexures, and mucosa. Most of XD develops in mucocutaneous lesions including skin, oral cavity and pharynx, however laryngeal involvement is uncommon. While the natural course of XD is usually benign and often self-limiting, but XD develop in critical anatomical locations may result in morbidity and mortality. Localized mucous lesions in oropharynx and larynx lead to dysphagia, dyspnea and air way obstruction. The diagnosis of XD was based on clinical, histological and immunohistochemical findings. The treatment is complex and non-consensual. Local treatment with cryotherapy, radiotherapy, surgery, and carbon dioxide lasers have been attempted with various results. Systemic medication with peroxisome proliferator-activated gamma receptors, statins, fenofibrate, chlorodeoxyadenosine, cyclophosphamide, doxycycline, and cyclosporine have also been reported, but none have proven particularly successful. A 59-year-old man presented with respiratory symptoms because of laryngeal involvement of XD. We had to remove the obstructive lesion for relieving the symptoms. We experienced XD in Larynx that was rare in otorhinolaryngology. So we report this case with review of literatures.
