As neonatal endotracheal intubation (ETI) is a low-frequency, high-consequence event, it is essential that providers have access to resources to aid in ETI. We sought to determine the impact of video laryngoscopy (VL) with just-in-time training on intubation outcomes over direct laryngoscopy (DL) when performed by neonatal nurses. We conducted a prospective, randomized, crossover study with neonatal nurses employed at a level 2 neonatal intensive care unit (NICU). Nurses performed both DL and VL on a neonatal mannequin using a CMAC (Karl Storz Corp, Tuttlingen, Germany) either with the assistance of the screen (VL) or without (DL)...

Various radiotherapy planning methods for T1N0 laryngeal cancer have been proposed to decrease normal tissue toxicity. We compare helical tomotherapy (HT), linac-based intensity-modulated radiation therapy (IMRT), volumetric-modulated arc therapy (VMAT), and 3-D conformal radiotherapy (3D-CRT) techniques for T1N0 laryngeal cancer. Overall, 10 patients with T1N0 laryngeal cancer were selected and evaluated. Furthermore, 10 radiotherapy treatment plans have been created for all 10 patients, including HT, IMRT, VMAT, and 3D-CRT...

BACKGROUND: Positioning of a lightwand in the midline of the oral cavity can be challenging in patients with cervical immobilization. Direct laryngoscopy may permit the lightwand tip to more easily access the glottic opening. We tested our hypothesis that a laryngoscope-assisted lightwand technique allows more successful endotracheal intubation than does a conventional lightwand approach. METHODS: A total of 162 patients requiring cervical immobilization during intubation for cervical spine surgery were allocated randomly to 2 groups...

OBJECTIVES/HYPOTHESIS: The primary suspicion for glottic malignancy during office laryngoendoscopy is based on lesion appearance. Previous studies investigating laryngeal use of narrow band imaging (NBI) are mostly descriptive. The additive value of NBI relative to white light (WL) requires further investigation. STUDY DESIGN: Observational matched study. METHODS: NBI was compared with WL images of 45 vocal fold lesions suspected for malignancy (21 carcinoma, 22 dysplasia, two benign)...

OBJECTIVE: To compare the effectiveness of the GlideRite stylet with the conventional malleable stylet (CMS) in endotracheal intubation (ETI) by the Macintosh laryngoscope. METHODS: This study is a randomized, crossover, simulation study. Participants performed ETI using both the GlideRite stylet and the CMS in a normal airway model and a tongue edema model (simulated difficult airway resulting in lower percentage of glottic opening [POGO]). RESULTS: In both the normal and tongue edema models, all 36 participants successfully performed ETI with the two stylets on the first attempt...

Transoral laser Assisted Microsurgical resection, Radiotherapy or Open partial laryngeal surgery are the management options for early glottic cancer. When endoscopic access is difficult(1-4) , radiotherapy or open surgery seems to be the other available options. The oncological safety of a Flexible Endoscopic Diode Laryngeal Laser Assisted Surgical (FEDLAS) Technique for patients with early glottic cancer and difficult laryngoscopy was tested in a preliminary pilot study. Patients with Grade three or more laryngoscopy(Cormack-Lehane classification)(5) and biopsy proven glottic cancer were included in the study...

A cohort study was undertaken to analyze the risk of recurrence among 1616 patients with primary squamous cell carcinoma of the larynx from 1983 to 2010 at a single, tertiary academic center in Oslo, Norway. The cohort was followed from the date of diagnosis to September 2011. Competing risk regression analysis assessed the association between various risk factors and the risk of recurrence, where death was considered a competing event. Recurrence was observed in 368 patients (23%) during the study period. The majority (71%) of recurrences involved the location of the primary tumor...

A 62-year-old man with a left temporal lobe tumor was scheduled for a semiurgent craniotomy for tumor excision. Previously, the patient had a laryngeal carcinoma that was resected and treated with chemotherapy and radiotherapy and a history of laryngeal biopsy with awake fiberoptic intubation. Because a difficult airway was anticipated, awake fiberoptic nasopharyngoscopy of the airway was performed under topical anesthesia in the operating room. This revealed a narrow glottic opening with no supraglottic pathology or friable tissue...

Bilateral vocal fold immobility (BVFI) is commonly caused by injury to the recurrent laryngeal nerve (RLN) and leads to stridor and dyspnea of varying onsets. A retrospective study was done at the Department of Otorhinolaryngology of Universiti Kebangsaan Malaysia Medical Centre on laser microsurgical posterior cordectomy for BVFI. The objectives were to identify the average duration of onset of stridor from the time of insult and to evaluate the outcome of laser posterior cordectomy as a surgical option. From 1997 to 2007, a total of 31 patients with BVFI were referred for surgery...

Sensory receptors are distributed throughout the oral cavity, pharynx, and larynx. Laryngeal sensitivity is crucial for maintaining safe swallowing, thus avoiding silent aspiration. Morphologic description of different receptor types present in larynx vary because of the study of many different species, from mouse to humans. The most commonly sensory structures described in laryngeal mucosa are free nerve endings, taste buds, muscle spindles, glomerular and corpuscular receptors. This study aimed at describing the morphology and the distribution of nerve endings in premature newborn glottic region...
