Adjustable Phonatory PEEP to Treat Dysphonia: A Preliminary Investigation of Progressive Masked Voice Exercises (PMVE).
Semin Speech Lang
December 2024
Intermountain Healthcare, Salt Lake City, Utah.
The Progressive Masked Voice Exercises (PMVE) with an innovative semioccluded ventilation mask fitted and adjustable positive end-expiratory pressure (PEEP) valve was evaluated. This study aimed to compare the effectiveness of the PMVE with the PEEP device and the Vocal Function Exercise (VFE) program on acoustic, auditory-perceptual, aerodynamic, and self-report measures. Twenty-five participants diagnosed with voice disorders met the criteria.

Article Synopsis
- Crocodylians have a specialized gular valve that forms a water-tight seal in their mouths, allowing them to dive while keeping their mouths open.
- This study reveals that the gular valve consists of an integrated dorsal component (the dorsal gular fold) and a mobile ventral part (the tongue and hyolingual apparatus), connected by a newly identified structure called the velar chord.
- The findings suggest that the tension in the velar chord changes the shape of the dorsal gular fold, affecting various behaviors like swallowing and vocalization beyond just diving.
Ortner's syndrome due to aneurysmal dilatation of the left pulmonary artery secondary to mixed pulmonary valve disease.
BMJ Case Rep
August 2024
Department of Radiology, Imperial College Healthcare NHS Trust, London, UK
Article Synopsis
- A young female patient experienced a 5-year history of worsening hoarseness and loss of voice, prompting a referral to an ENT clinic.
- A chest X-ray revealed significant enlargement of the left pulmonary artery, but no signs of pulmonary arterial hypertension were detected.
- The provisional diagnosis indicated that the left recurrent laryngeal nerve was being compressed by the left pulmonary artery and aortic arch, a condition known as Ortner's syndrome, which was later confirmed through various diagnostic tests.
Introduction: Tracheostomy is a common emergency procedure for critically ill patients to secure their airway. The speaking valve is a one-way ventilation valve that is attached to the end of the tracheostomy tube to help the patient remodel subglottic pressure. However, the efficacy and safety of speaking valves in adult patients with tracheostomy remain controversial.

Department of Ear, Nose and Throat Surgery, The Royal London Hospital, Bart's NHS Trust, London, UK.
This case report describes a man in his mid 40s, with a history of chronic smoking, who presented with dysphonia. He underwent microlaryngoscopy and biopsy for a suspicious lesion on the anterior right vocal cord. Mask ventilation proved difficult on induction of general anaesthesia due to a solid lesion acting as a ball valve into the glottis.
