Neck mass is a common clinical finding in all age groups. Although most neck masses have the nature of benign processes, malignant diseases must ruled out. Careful medical history, such as the duration of the mass, the presence of pain, history of upper airway infection, contact history of animals, and travel, should be obtained. Thorough physical examination should be also performed. The patients' age and the location, size, and duration of the neck masses are important pieces of information. Neck masses in children (0 to 15 years) are more commonly inflammatory than congenital or developmental and those in young adult (16~ 40 years) are more commonly congenital than neoplastic. However, the first consideration in elderly adults (>40 years) should be neoplasia. The location of the mass is particularly important with respect to the differentiation between congenital and developmental masses because such lesions are consistent in their location. For metastatic neck masses, their location may be the key to the identification of the primary tumor. Inflammatory and infectious causes of neck masses, such as cervical adenitis and cat-scratch disease, are common in young adults. The progressively increasing size of the mass indicates malignancy, however, a rapid change of size usually suggests an infectious mass. Congenital masses, such as branchial anomalies and thyroglossal duct cysts, should be considered in the differential diagnosis. Neoplasms (benign and malignant) are more likely to be present in older adults. Ultrasonography-guided biopsy is the best diagnostic method for evaluating neck masses. Panendoscopy (nasopharyx, palatine tonsil, base of tongue, piriform sinus, esophagus, stomach, trachea, and lungs) must be performed in all patients of malignant disease. The Open biopsy should be performed only in case of the neck masses which persist beyond four to six weeks after a single course of a broad-spectrum antibiotic or suspects the malignat lymphoma.

BACKGROUND AND OBJECTIVES: High-speed videolaryngoscopy (HSV) is the only technique that captures the true intra-cycle vibratory behavior of the vocal folds by capturing full images of the vocal folds. However, it has problems of no immediate feedback during examination, considerable waiting time for digital kymography (DKG), recording duration limited to a few seconds, and extreme demands for storage space. Herein, we demonstrate a new post-processing method that converts HSV images to two-dimensional digital kymography (2D-DKG) images, which adopts the algorithm of 2D videokymography (2D VKG). MATERIALS AND METHODS: HSV system was used to capture images of vocal folds. HSV images were post-processed in Kay image-process software (KIPS), and conventional DKG images were retrieved. Custom-made post-processing system was used to convert HSV images to 2D-DKG images. The quantitative parameters of the post-processed 2D-DKG images was validated by comparing these parameters with those of the DKG images. RESULTS: Serial HSV images for all phases of vocal fold vibratory movement are included. The images were converted by the scanning method using U-medical image-process software. Similar to conventional DKG, post-processed 2D DKG image from the HSV image can provide quantitative information on vocal fold mucosa vibration, including the various vibratory phases. Differences in amplitude symmetry index, phase symmetry index, open quotient, and close quotient between 2D-DKG and DKG were analyzed. There were no statistical differences between the quantitative parameters of vocal fold vibratory movement in 2D-DKG and DKG. CONCLUSION: The post-processing method of converting HSV images to 2D DKG images could provide clinical information and storage economy.

BACKGROUND AND OBJECTIVES: Advanced or recurrent laryngeal cancers after chemoradiotherapy were mainly treated by total laryngectomy because of inadequate surgical margin, multifocal recurrent site, and delayed diagnosis. Recently, voice preservation through conservative laryngeal surgery in case of advanced or recurrent laryngeal cancer with strict application of surgical indication became possible. In this study, authors studied the usefulness of surpracricoid partial laryngectomy (SCPL) for advanced or recurrent laryngeal cancers is discussed. MATERIALS AND METHOD: Twenty-five laryngeal cancer cases of cricohyoido-epiglottopexy (CHEP) or cricohyoidopexy (CHP) from May 1996 through April 2001 were analysed retrospectively. In recurrent cases after radiotherapy, there were 8 cases with glottic T1, 6 with T2, 3 with T3, one with T4, one with supraglottic T2 and T3. In advanced cases without radiotherapy, there were 3 cases with glottic T3 and 2 with supraglottic T3. Evaluation of oncological and functional results were conducted. The mean follow-up period was 29.1 months. RESULTS: Local recurrence occurred in 1 patient (4.3%) and cricoid perichondritis in 5 patients (21.7%), laryngocutaneous fistula in 1 patient (4.3%) after the operation. Four patients (17.3%) had to be treated with completion laryngectomy. Voice function was preserved in 19 patients (82.7%). CONCLUSION: Our experience with supracricoid partial laryngectomy with CHEP or CHP suggests that this technique can be a valuable alternative to the total laryngectomy in the recurrent or advanced laryngeal cancer.

BACKGROUND AND OBJECTIVES: Supracricoid partial laryngectomy (SCPL), one of the conservative techniques for supraglottic laryngectomy, can be used to control advanced laryngeal cancers extending to paraglottic space, thyroid cartilage with or without epiglottis and preepiglottic space. This procedure can preserve physiologically phonatory and swallowing function, and achieve similar local control rates as total laryngectomy but voice quality is somewhat less efficient than that of normal speakers. Authors evaluated prospectively speech and voice parameters for efficiency of phonation in patients treated with SCPL for recurrent laryngeal carcinoma after primary radiotherapy. MATERIALS AND METHODS: Authors compared 5 male patients who underwent SCPL with 8 normal subjects of the same age. RESULTS: No significant difference of phonatory function was found between subjects before or 3 to 6 months after the operation. However, MPT, C/B, jitter and shimmer were significantly different between the normal and post-operative 3 months group (p<0.05) and jitter and shimmer between the normal and post-operative 6 months group (p<0.05). CONCLUSION: All patients complained of breathy voice but could not breathe through the oro-nasal airway and swallow without aspiration within 2 to 3 months after SCPL. In conclusion, SCPL is a recommendable procedure in selected cases of laryngeal cancer which can not be controlled by vertical partial laryngectomy or supraglottic laryngectomy.
