REVIEW
Heather Shaw Bonilha, Maude Desjardins, Kendrea L Garand, Bonnie Martin-Harris
OBJECTIVE: Laryngeal endoscopy with stroboscopy, a critical component of the assessment of voice disorders, is rarely used as a treatment outcome measure in the scientific literature. We hypothesized that this is because of the lack of a widely used standardized, validated, and reliable method to assess and report laryngeal anatomy and physiology, and undertook a systematic literature review to determine the extent of the inconsistencies of the parameters and scales used in voice treatment outcome studies...

PURPOSE OF REVIEW: The management of benign vocal fold lesions (BVFLs) continues to evolve. This article will review the recent literature surrounding the nomenclature, cause, diagnosis, and treatment of BVFLs, including polyps, nodules, cysts, and reactive lesions. RECENT FINDINGS: The taxonomy of vocal fold lesions has been refined, and it serves as a common descriptive language for diagnosis, treatment algorithms, and reporting of outcomes. Though these lesions are known to be the result of phonotrauma, investigation into inflammatory mediators, apoptosis, and laryngopharyngeal reflux provide further elucidation of their underlying pathophysiology...

T J Gal, Brian Hixon, Paul Zhang
This case report describes the use of trans-oral robotic surgery (TORS) for the excision of a combined laryngocele. Mixed or combined laryngoceles extend from the supraglottic larynx through the thyrohyoid membrane into the neck. Surgical excision for these benign lesions often requires combined external (transcervical) and internal (transoral endoscopic) approaches which carry significant morbidity. We present the case of a 37-year-old male who was diagnosed with a large laryngopyocele and was subsequently managed with a transoral excision using the da Vinci Si surgical robot system...

F Minary, D Rabus, G Martin, J-M Friedt
Stroboscopy provides an energy and computationally efficient means of sampling radiofrequency and microwave signals assumed to be reproducible under external excitation. While well known for impulse mode RADAR receivers, we here investigate its use for interrogating surface acoustic wave (SAW) transducers acting as passive cooperative targets. Amongst the originality of the implementation is the need to keep phase coherence between successive pulse generations which last up to tens of the radiofrequency periods to optimally transfer energy to the transducer...

Purpose: Videostroboscopy (VS) uses an indirect physiological signal to predict the phase of the vocal fold vibratory cycle for sampling. Simulated stroboscopy (SS) extracts the phase of the glottal cycle directly from the changing glottal area in the high-speed videoendoscopy (HSV) image sequence. The purpose of this study is to determine the reliability of SS relative to VS for clinical assessment of vocal fold vibratory function in patients with mass lesions. Methods: VS and SS recordings were obtained from 28 patients with vocal fold mass lesions before and after phonomicrosurgery and 17 controls who were vocally healthy...

BACKGROUND: Multi-step cancerogenesis guides laryngeal cancer onset and it includes a wide variety of pre-cancerous lesions macroscopically challenging to identify and distinguish from initial cancerous foci. OBJECT: Different modalities of diagnostic techniques of laryngeal epithelial lesions exist and they do not offer a single system to make a differential diagnosis. Hence, this meta-analysis aimed to synthesize the validity of each single diagnostic tool to improve laryngeal patient management...
