Objective—Extent of vocal fold injury impacts the nature and timing of wound healing, and voice outcomes. However, depth and extent of the lesion created to study wound healing in animal models vary across studies, likely contributing to different outcomes. Our goal was to create a surgery classification system to enable comparison of postoperative outcomes across animal vocal fold wound healing studies.
Study design—Prospective, controlled animal study.
Methods—Rats underwent one of three types of unilateral vocal fold surgeries classified by depth and length of resection. The surgeries were a subepithelial injury, resection of epithelium and superficial layer of the lamina propria …

Purpose: Vocal fold epithelium is composed of layers of individual epithelial cells joined by junctional complexes constituting a unique interface with the external environment. This barrier provides structural stability to the vocal folds and protects underlying connective tissue from injury while being nearly continuously exposed to potentially hazardous insults, including environmental or systemic-based irritants such as pollutants and reflux, surgical procedures, and vibratory trauma. Small disruptions in the epithelial barrier may have a large impact on susceptibility to injury and overall vocal health. The purpose of this article is to provide a broad-based review of current knowledge of the vocal …

This chapter addresses Spanish-speaking, English Language Learners (ELLs) in the United States (U.S.) who are sequential bilinguals; that is, oral and written English is acquired as a second language (L2) at school. Within this population, substantial variation exists with regard to individual students’ language and literacy learning experiences. The specific focus here is the writing patterns of ELLs with atypical language development, who often present with multiple complexities in authenticating their language learning profiles in both Spanish and English.

Objectives/Hypothesis: An intact epithelium is an important part of vocal fold defense. Damage to the epithelium can compromise vocal fold homeostasis and protection of the host tissue from viral and bacterial invasion. Elucidating the effects of damage on epithelial architectural and barrier integrity provides insight into the role of epithelium in protecting vocal folds. Using an animal model, we evaluated the time course of structural and functional epithelial restoration following injury. Study Design: Prospective, controlled animal study. Methods: Forty rats underwent surgery to remove vocal fold mucosa unilaterally. Larynges were harvested at five time intervals between 3 to 90 days …
