Late effects of head and neck cancer (HNC) treatment include profound dysphagia, chronic aspiration, death. Functional laryngectomy (FL) can improve patient survival quality life (QoL); however, removing a failing larynx for noncancer reason is difficult decision. Data regarding the ability FL to self-perceptions voice, swallowing, QOL in survivors HNC with intractable aspiration are inconclusive.

The purpose this investigation was to determine the validity reliability PILL-5, self-administered patient reported outcome measure (PROM) quantify degree (tablet capsule) dysphagia. Pill-5 5-item questionnaire maximum symptom score 20. Methods: PILL-5 administered 190 patients referred for videofluoroscopic esophagography (VFE). Construct assessed by...

Objective Liquid thickeners are commonly recommended in individuals with dysphagia and recurrent aspiration as a strategy for pneumonia prevention. The goal of this study was to examine the effects small amounts aspirated liquid thickener on lungs. Study design Animal model. Prospective animal clinical trial. Methods Adult Sprague Dawley rats (n = 19) were divided into two groups underwent three intratracheal instillations either xanthan gum‐based nectar‐thick water (0.1–0.25 mL/kg) or...

Introduction: Multiple system atrophy (MSA) has detrimental effects on swallowing function. The function of patients with MSA not been systematically characterized and the underlying pathophysiological mechanisms dysphagia remain poorly understood. Objectives: To investigate characteristics swallow in using high-resolution manofluorography (HRMF). Methods: We conducted a retrospective review twenty-five who underwent HRMF from 2016 to 2017. was utilized only oral diet (Functional Oral Intake...

Objectives/Hypothesis Contrast agent (CA) aspiration is an established complication of upper gastrointestinal and videofluoroscopic swallow studies. The underlying molecular biological mechanisms acute response to CA in the respiratory organs remain unclear. aims this study were elucidate histological influences three kinds CAs on lung clarify differences responses. Study Design Animal model. Methods Eight‐week‐old male Sprague Dawley rats divided into five groups (n = 6 each group). Three...

To evaluate the precise objective fluoroscopic abnormalities in persons with dysphagia following anterior cervical spine surgery (ACSS).129 patients after ACSS were age and sex matched to 129 healthy controls. All individuals underwent videofluoroscopic swallow study (VFSS). VFSS parameters abstracted included upper esophageal sphincter (UES) opening, penetration aspiration scale (PAS), pharyngeal constriction ratio (PCR). Other data collected patient-reported outcome measures of voice...

Abstract Background Laryngopharyngeal sensory neuropathy (LSN) has been observed to be a contributing factor swallowing dysfunction in head and neck cancer (HNC) survivors. Methods Retrospective review of 43 tube‐dependent HNC survivors was conducted. LSN assessed with direct palpation the aryepiglottic fold by traversing true vocal folds without eliciting cough reflex flexible laryngoscope. Results The primary tumor sites were oropharynx (51%), larynx (14%), nasopharynx (4.7%), oral cavity...

Objective Radiotherapy of head and neck cancer (HNCA) causes dysfunction through radiation‐induced fibrosis (RIF). We hypothesize that the degree cervical is associated with swallowing dysfunction. This study evaluated association between in patients after radiation therapy for HNCA. Study Design Cross sectional study. Methodology A convenience sample dysphagia who were at least 1 year post HNCA underwent simultaneous ultrasound (US) video‐fluroscopic swallow (VFSS). US determinants...

Objectives/Hypothesis Penetration and aspiration during the oropharyngeal swallow have different clinical implications.
