Gender Disparities in Voice Outcomes After Tracheoesophageal Puncture in Total Laryngectomy Patients (UC Davis)

To perform a multi-site prospective study assessing, both subjectively and objectively, the gender disparities in speech outcomes of patients using TEP after total laryngectomy.

The investigators hypothesize that speech outcomes, both subjective and objective measures, will be significantly poorer for female patients compared to male patients. The outcome of the study is to prospectively assess both subjective and objective gender disparities in voice and speech outcomes of patients using TEP after total laryngectomy across a multiple institutions. The investigators hypothesize that both subjective and objective measurements of voice, speech and quality of life will be poorer for female patients in comparison to male patients.

Total laryngectomy (TL) is typically performed in patients with advanced laryngeal cancer as a means of removing the entire larynx and surrounding structures that have been affected by the malignancy. Following total laryngectomy, patients lose ability to produce voice. Thus, they require the use of alternative methods of to produce voice along with extensive speech rehabilitation. Currently, there are three main speech alternative options, esophageal speech, tracheoesophageal speech, and electrolarynx speech. The focus of this study will be on patients rehabilitating their speech using tracheosophgeal speech through a tracheoesophageal prosthesis (TEP). It has been shown that generally for TL patients, better voice quality and satisfaction with voice is associated with improved quality of life. Currently, speech rehabilitation outcomes are measured with a multidimensional approach, using various scales ranging from acoustic analysis, perceptual evaluation, and patient-reported outcomes. The majority of studies analyzing outcomes in total laryngectomy patients, however, is predominated by assessment of the male laryngectomee population. Historically, this has been due to the greater incidence of laryngeal cancers in males than females. Due to this, there has been minimal research investigating potential gender differences in the laryngectomy population. Of the limited data available regarding the female laryngectomee population, it has been shown that gender frequency differences seen in normal subjects are lost following total laryngectomy and the resulting tracheoesophageal voice is more similar to the normal male voice, thus females face a greater voice handicap compared to their male counterparts (Kazi, 2006; Deore, 2011). While some studies have assessed the resulting quality of life differences between the genders in the laryngectomy population (Lee, 2010), few have investigated voice outcomes using both subjective and objective scales as used in this study. The outcomes of this study will be key to understanding what metrics are potentially contributing to the voice and lifestyle dissatisfaction that prior studies have demonstrated in the female laryngectomee population. This quantifiable data will provide a way of modifying future voice rehabilitation in the female population to enable better satisfaction and minimize gender differences in voice outcomes.
