Functional MRI during tongue strength tasks before and after partial glossectomy: Insights into the cortical activation of tongue motor function.

Aim: Because the tongue is a midline structure, studies on the neural correlates of lateralized tongue function are challenging and remain limited. Patients with tongue cancer who undergo unilateral partial glossectomy may be a unique cohort to study tongue-associated cortical activation, particularly regarding brain hemispheric lateralization. This longitudinal functional magnetic resonance imaging (fMRI) study investigated cortical activation changes for three tongue tasks before and after left-sided partial glossectomy in patients with squamous cell carcinoma of the tongue.

Correction to: Volumetric Changes to the Pharynx in Healthy Aging: Consequence for Pharyngeal Swallow Mechanics and Function.

This erratum notifies the readers of the Dysphagia journal of an error in the original published version of this manuscript. In that manuscript, a previously available open source spreadsheet tool was used to calculate the position of the posterior laryngeal air column on lateral view videofluoroscopic images as a proxy for the bottom of the pharynx. We have subsequently been made aware of an error in the mathematical formula built into the spreadsheet, which resulted in a reversal of the results for the X and Y planes of measurement.

Motor Learning, Neuroplasticity, and Strength and Skill Training: Moving From Compensation to Retraining in Behavioral Management of Dysphagia.

Purpose Learning a motor skill and regaining a motor skill after it is lost are key tenets to the field of speech-language pathology. Motor learning and relearning have many theoretical underpinnings that serve as a foundation for our clinical practice. This review article applies selective motor learning theories and principles to feeding and swallowing across the life span.

Speech-Language Pathology Guidance for Tracheostomy During the COVID-19 Pandemic: An International Multidisciplinary Perspective.

Purpose As the COVID-19 pandemic has unfolded, there has been growing recognition of risks to frontline health care workers. When caring for patients with tracheostomy, speech-language pathologists have significant exposure to mucosal surfaces, secretions, and aerosols that may harbor the SARS-CoV-2 virus. This tutorial provides guidance on practices for safely performing patient evaluation and procedures, thereby reducing risk of infection.

Effects of jaw exercise intervention timing on outcomes following oral and oropharyngeal cancer surgery: Pilot study.

Background: Common in head and neck cancer patients, trismus can make speech and swallowing difficult and can compromise quality of life (QOL). Jaw range of motion exercise therapy may prevent or treat trismus in surgical patients. While the importance of these exercises is well-documented, there is little literature regarding the optimal timing of exercise initiation.

The impact of time after radiation treatment on dysphagia in patients with head and neck cancer enrolled in a swallowing therapy program.

Background: Swallowing dysfunction after radiotherapy (RT) for head and neck cancer can be devastating. A randomized control trial compared swallow exercises versus exercise plus neuromuscular electrical stimulation therapy and found no overall difference in outcomes.

Methods: Quality of life (QOL), diet, and swallowing variables collected at discrete intervals on 117 patients were reanalyzed to test the hypothesis that shorter time between the completion of radiotherapy and beginning of the swallowing therapy program yielded improved outcomes.

Prospective instrumental evaluation of swallowing, tongue function, and QOL measures following transoral robotic surgery alone without adjuvant therapy.

Background: Transoral robotic surgery (TORS) has been utilized to deintensify treatment. No studies have measured swallow safety and efficiency, nor assessed the functional impact of TORS alone.

Methods: This prospective cohort underwent baseline and 1-month postsurgery assessments including modified barium swallow evaluation, using the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) rating system, tongue range of motion assessment, the Performance Status Scale (PSS), and quality of life with the MD Anderson Dysphagia Inventory (MDADI).

Objective and subjective hyposalivation after treatment for head and neck cancer: Long-term outcomes.

Objectives/hypothesis: This study examined saliva weight over time and its association with diet and patient-rated swallowing, dry mouth, sticky saliva, and dysgeusia quality of life in head and neck cancer (HNCA) patients treated with surgery plus adjuvant chemoradiotherapy (CRT), or primary CRT.

Study Design: Prospective cohort study in an outpatient HNCA center setting.

Methods: Patients were seen pretreatment, and 1, 3, 6, 12, 24, and 36 + months post-treatment.

Volumetric Changes to the Pharynx in Healthy Aging: Consequence for Pharyngeal Swallow Mechanics and Function.

Pharyngeal lumen volume is prone to increase as a consequence of pharyngeal muscle atrophy in aging. Yet, the impact of this on swallowing mechanics and function is poorly understood. We examined the relationship between pharyngeal volume and pharyngeal swallowing mechanics and function in a sample of healthy community-dwelling seniors.

Swallow Event Sequencing: Comparing Healthy Older and Younger Adults.

Previous research has established that a great deal of variation exists in the temporal sequence of swallowing events for healthy adults. Yet, the impact of aging on swallow event sequence is not well understood. Kendall et al.

Alterations to Swallowing Physiology as the Result of Effortful Swallowing in Healthy Seniors.

A significant proportion of healthy seniors report difficulty swallowing, thought to result from age-related decline in muscle bulk/function. Effortful Swallowing (ES) is used both as a compensatory maneuver to improve pharyngeal propulsion/clearance and has been proposed as an exercise to improve pharyngeal strength. This study sought to quantify the immediate kinematic, temporal, and functional changes during an ES maneuver to quantify its exercise potential to combat age-related changes in swallowing.

Total lower lip and chin reconstruction with radial forearm free flap: A novel approach.

Background: The management of large chin and lower lip defects is challenging due to this facial subunit's tremendous functional and aesthetic importance. Specific methods for total lower lip and mentum reconstruction are not well chronicled. Aesthetic and functional goals of this reconstruction include restoration of oral competence by maintaining lower lip height, vermilion reestablishment, color-matched skin introduction to the chin, sensation restoration, and ideally restoration of dynamic activity to the lower lip.

Prophylactic Swallow Therapy for Patients with Head and Neck Cancer Undergoing Chemoradiotherapy: A Randomized Trial.

Evidence supporting prophylactic swallow exercises for patients with head and neck cancer (HNC) has not been universally demonstrated. This RCT examined diet level, feeding tube use, swallow function, and quality of life (QOL) of patients undergoing chemoradiotherapy who performed prophylactic swallowing exercises. Sixty HNC patients were randomized into exercise versus control groups.

Impact of Compliance on Dysphagia Rehabilitation in Head and Neck Cancer Patients: Results from a Multi-center Clinical Trial.

A 5-year, 16-site, randomized controlled trial enrolled 170 HNC survivors into active (estim + swallow exercise) or control (sham estim + swallowing exercise) arms. Primary analyses showed that estim did not enhance swallowing exercises. This secondary analysis determined if/how patient compliance impacted outcomes.

Dynamic Imaging Grade of Swallowing Toxicity (DIGEST): Scale development and validation.

Background: The National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE) is the universal framework for toxicity reporting in oncology trials. The objective of this study was to develop a CTCAE-compatible modified barium swallow (MBS) grade for the purpose of grading pharyngeal dysphagia as a toxicity endpoint in cooperative-group organ-preservation trials for head and neck cancer (HNC). It was hypothesized that a 5-point, CTCAE-compatible MBS grade (Dynamic Imaging Grade of Swallowing Toxicity [DIGEST]) based on the interaction of pharyngeal residue and laryngeal penetration/aspiration ratings would be feasible and psychometrically sound.

Staged laryngeal reconstruction with a prefabricated flap for radiation recurrent glottic carcinoma.

Objectives/hypothesis: Although salvage total laryngectomy remains the definitive approach to recurrent/persistent glottic cancer following failed radiation therapy for favorable early-stage disease, it comes at the price of a permanent laryngostome and an impact on quality of life. We describe a three-stage method of laryngeal reconstruction for salvage partial laryngectomy to address the unique challenges of operating on radiation recurrent/persistent cancer.

Study Design: This was a single-surgeon retrospective case series of patients who underwent a three-stage laryngeal reconstruction for salvage partial laryngectomy.

Efficacy of electrical stimulation and exercise for dysphagia in patients with head and neck cancer: A randomized clinical trial.

Background: Neuromuscular electrical stimulation (NMES) is a highly sought after but poorly studied treatment for dysphagia among patients with head and neck cancer with dysphagia. This study investigated the efficacy of NMES in this patient population.

Methods: In this double-blinded, randomized controlled trial, 170 patients with head and neck cancer experiencing posttreatment dysphagia were randomized into active NMES + swallow exercise versus sham NMES + swallow exercise groups.

Background: Our surgical approach describes a bipaddled radial forearm free flap (RFFF) for closure of chronic tracheoesophageal fistulae (TEF) in patients who underwent total laryngectomy. The desired functional results were achieved.

Methods: Eight patients underwent the procedure.

A survey of variables used by speech-language pathologists to assess function and predict functional recovery in oral cancer patients.

Oromotor and clinical swallow assessments are routinely performed by speech-language pathologists (SLPs) who see head and neck cancer (HNC) patients. However, the tools used to assess some of these variables vary. SLPs routinely identify and quantify abnormal functioning in order to rehabilitate the patient.

Special groups: head and neck cancer.

Head and neck cancer is a unique cause of dysphagia. Altered swallow function can be secondary to the mechanical effects of a tumor invading normal anatomy needed for deglutition, or as a direct sequela of cancer treatment (surgery and/or radiation ± chemotherapy). This article outlines the incidence of head and neck cancer, effects of anatomic changes associated with common surgical intervention, and the consequences of treatment-induced dysphagia.

Tongue strength as a predictor of functional outcomes and quality of life after tongue cancer surgery.

Objectives: Surgical resection of oral cancer can result in altered speech, swallowing, and quality of life (QOL). To date, the oral outcome variables of tongue strength, tongue and jaw range of motion, and saliva production have not been extensively assessed. This pilot study was done to assess tongue strength along with other oral outcomes and their relationship to performance status for speech, swallowing, and QOL after partial glossectomy.

Dynamic magnetic resonance imaging of the pharynx during deglutition.

Objectives: We utilized dynamic magnetic resonance imaging to visualize the pharynx and upper esophageal segment in normal, healthy subjects.

Methods: A 3-T scanner with a 4-channel head coil and a dual-channel neck coil was used to obtain high-speed magnetic resonance images of subjects who were swallowing liquids and pudding. Ninety sequential images were acquired with a temporal resolution of 113 ms.

3 Tesla turbo-FLASH magnetic resonance imaging of deglutition.

Objectives/hypothesis: In this article we describe a methodology for obtaining high-quality dynamic magnetic resonance imaging (MRI) sequences of the swallow sequence in healthy volunteers. The study includes comparison to previous work done in our lab using a 1.5 Tesla (T) magnet.

Comprehensive approach to restoration of function in patients with radiation-induced pharyngoesophageal stenosis: report of 31 patients and proposal of new classification scheme.

Background: The treatment for upper aerodigestive tract malignancy with external beam radiation therapy and chemotherapy can result in a "cure," yet result in pharyngoesophageal (PE) stenosis. To improve communication, compare therapeutic results, and assist in treatment planning, we developed a new classification system to describe PE stenoses. Additionally, we analyzed our 6-year experience.
