A laryngeal foreign body (FB) is a significant, life-threatening event in the paediatric population. Incomplete airways obstruction by a thin, laminar, radiolucent FB lodged in the glottis or supraglottis is a rare occurrence that may present with non-specific symptoms, absence of chest findings, and normal radiographic investigations, resulting in misdiagnosis, delay in diagnosis, or prolonged recovery. We report two cases of 10-month-old male infants, each with a thin radiolucent FB lodged between the vocal folds that was detected with low-dose multidetector computed tomography (MDCT) and thin-slice reconstruction...

Mammalian attachment behaviors, such as crying, are essential for infant survival by receiving food, protection, and warmth from caregivers. Ultrasonic vocalization (USV) of infant rodents functions to promote maternal proximity. Impaired USV emission has been reported in mouse models of autism spectrum disorder, suggesting that USV is associated with higher brain function. In utero and lactational dioxin exposure is known to induce higher brain function abnormalities in adulthood; however, whether perinatal dioxin exposure affects behavior during infancy is unclear...

Hoarseness is a common presentation in primary care practices. Combined with other voice-related changes, it falls under the umbrella diagnosis of dysphonia. Hoarseness has a number of causes, ranging from simple inflammatory processes to less common psychiatric disorders to more serious systemic, neurologic, or cancerous conditions. Medication-induced hoarseness is common and should be considered. The initial evaluation begins with a targeted history and physical examination, while also looking for signs of potential systemic etiologies...

OBJECTIVES: The hard onset, also known as a hard attack, or glottal onset, is a technique of vocal production in which the vocal folds are adducted prior to exhalation and forced open to begin phonation. In this study, we assessed the short-term efficacy of voice therapy incorporating hard onset techniques for patients with functional hypoadduction and presbyphonia. DESIGN: Prospective cohort study. SETTING: Tertiary academic medical center...

The development of the therapeutic possibilities of vocal cord immobility necessitated the parallel renewal of diagnostic methods. In the last years, laryngeal electromyography, which was first introduced more than 70 years ago, has been re-discovered. After reviewing the international literature and their own experience, the authors present the indications, technical requirements, method and, particularly, the evaluation of the results of this procedure. Laryngeal electromyography makes the differentiation between mechanical fixation and immobility with neurological origin of the vocal folds possible...

Human phonation is based on the interaction between tracheal airflow and laryngeal dynamics. This fluid-structure interaction is based on the energy exchange between airflow and vocal folds. Major challenges in analyzing the phonatory process in-vivo are the small dimensions and the poor accessibility of the region of interest. For improved analysis of the phonatory process, numerical simulations of the airflow and the vocal fold dynamics have been suggested. Even though most of the models reproduced the phonatory process fairly well, development of comprehensive larynx models is still a subject of research...

A French bulldog with a previous history of leishmaniosis was presented due to respiratory distress associated with a laryngeal mass. The mass was excised and cytological and histopathological examination revealed pyogranulomatous inflammation with Leishmania spp. amastigotes. After surgery, the respiratory condition resolved; however, 3 months later the dog developed clinicopathological signs of leishmaniosis, which improved with systemic treatment. This case shows an atypical presentation of leishmaniosis with a focal tumour-like mass in the vocal folds as the only clinical sign...

Giant cell tumor of the larynx is a rare tumor. It was first reported by Wessely et al in 1940. Thirty-nine cases have been reported until now and together with the current case 2 recurrences were encountered. In this case report, our aim was to discuss conservative management because of the suspicion of recurrence. A 70-year-old male patient was admitted to our clinic with the complaint of hoarseness. A tumor measuring 1 × 1 cm located in the anterior half right vocal fold and extending to the anterior comissure was found on laryngeal endoscopy...

OBJECTIVES: Bilateral vocal fold paralysis (VFP) is a severe complication after laryngotracheal (LT) surgery. The reduced glottic opening leads to significant respiratory distress immediately after the operation and requires the placement of a tracheostomy in most cases. Patients with a pre-existing unilateral VFP or expected recurrent nerve resection are at the highest risk for glottic failure. These patients might benefit from a pre-emptive glottic enlargement before LT surgery. METHODS: We performed a retrospective review of patients who received a pre-emptive glottis enlargement before LT surgery at the Medical University of Vienna from October 2011 to December 2016...

There is a growing need for evaluation tools allowing the quantification of the outcome after voice surgeries. Since the end of the 1990s, multiple unfruitful attempts have been made to reach a consensus, including the Dejonckere protocol for the European Laryngological Society in 2001. This suggested to perform objective and quantifiable measures in the following domains: perception, acoustic, aerodynamic, self-evaluation by the patient and videolaryngostroboscopy. But in a PubMed® search with the keywords "Voice Assessment" and "Voice Outcome" since 2001 retrieving 452 articles, only 33 of them were using methods taking into account the first four dimensions proposed by Dejonckere...

W-F Su, M-C Lan, S-C Liu
A suture lateralisation (SL) instead of an endolaryngeal tissue ablation procedure under endoscopy has been utilised to treat bilateral vocal fold immobility (BVFI) since 1980. However, mechanical fixation (MF) of the cricoarytenoid joint (CAJ) has continually challenged the effectiveness of glottic dilatation both in the SL procedure and the tissue ablation procedure. From 2007 to 2015, a total of 38 patients with BVFI underwent 40 exo-endolaryngeal suture lateralisation (exoeSL) procedures and three were diagnosed with MF in our hospital...

OBJECTIVE: Paradoxical vocal fold motion (PVFM) is responsive to behavioral therapy, often resulting in a remission of symptoms, but little is known about whether treatment is beneficial with regard to PVFM-associated psychological symptoms or functional limitations. The goal of the study was to identify patient perceptions of the impact of treatment for PVFM and characteristics associated with treatment outcomes. METHODS: A survey was conducted of all adults who had received at least 1 session of treatment for PVFM in our outpatient clinic over a 2-year period...
