The etiology and pathogenesis of laryngeal microwebs are heterogeneous, and in most cases they are an incidental finding. It has also been suggested that microwebs could be a familial trait, representing a postblastogenic embryonic vestigial structure that might alter the biomechanical and vibratory properties of the vocal fold. Vocal nodules are small benign swellings along the margins of the vocal cords, with preferential location at the junction of the anterior and middle thirds, and usually resulting from mechanical trauma. The authors studied a sample of 107 patients with vocal nodules, looking for a possible correlation with microwebs due to the predicted involvement in the vibration of vocal cord margins. Glottic proportion, type of glottic closure, nodule location and the main complaints in patients with microwebs were compared with those in a sample of patients without microwebs. In the present study, microwebs were found in 9.4% of the patients, who showed much smaller glottic proportion than patients with micronodules only. Furthermore, vocal nodule location was not related to the presence and/or absence of laryngeal microwebs.

    ABSTRACT: It has become the current trend to measure the status of a scientific journal by its impact factor and to measure a scientist by the impact factor of journals in which he/she publishes. While the underlying idea is good, applying the measure universally leads to highly disturbing trends. Based on country policies, some universities and their departments, especially in Europe, have started to distribute finances based on the average impact factor and average ‘relative impact factor’ (i.e., journal ranking based on impact factor within a subject category recognized by the Thomson Scientific Institute for Scientific Information, ISI) calculated from all the publications published by the scientific staff. In order to financially survive, the scientific staff should publish in journals with the highest impact factor possible. Any publication in a journal with a low impact factor or low relative impact factor decreases the overall score of the department. Consequently, researchers are strongly recommended to avoid journals with low impact factors.

    ABSTRACT: Vocal fold masses are often complex in nature and can have a devastating result on the professional voice. These lesions are usually multifactorial with synergistic contributions over time from voice use demands and technique, medical conditions, medications, and the environment. General categories of benign vocal fold masses in professional voice include nodules, polyps, and cysts, but other pathology should be considered, such as reactive lesions, intracordal scarring, feeding varices, and reparative granuloma. A perspective on these issues is essential for proper diagnosis and management. Video procedures for nodule and polyp surgery accompany this content online.
