Abstract

Immunoglobulin G4 (IgG4)-related disease is an immune-mediated disorder that commonly manifests in the salivary glands. As a recently described disorder, the description and classification of IgG4-related disease is an ongoing process. Diagnosis of IgG4-related disease requires integration of clinical history, histopathology, and radiographic findings, including ultrasonography and sialography. In this case report, we correlate parotid ultrasonographic and sialographic findings in a patient with proven IgG4-related disorder confirmed from analysis of previous submandibular gland resections. We aim to highlight the utility of multimodality imaging in the diagnosis of IgG4-related disease. [ABSTRACT FROM AUTHOR]

Abstract

This article discusses the use of a modified sclerotherapy needle catheter as a protective sheath for laser fiber passage in channelled flexible laryngoscopes. The authors found that the sharp tip of the laser fiber can cause damage to the working channel of the laryngoscope, leading to costly repairs. They propose using a 25-gauge sclerotherapy needle catheter as a sheath to protect the working channel during laser fiber insertion. The study found that this method was effective in preventing damage to the laryngoscope and resulted in no reported repairs. The authors suggest that this inexpensive alternative could be used to protect the working channel during ablative laryngeal procedures. [Extracted from the article]

10. Anatomic Variability of the Accessory Nerve: Implications for Dissection of Level IIB.

Author

Pagedar, Nitin A. and Hoffman, Henry T.

Abstract

Objectives: During neck dissection, level IIB lymphadenectomy necessitates manipulation of the spinal accessory nerve that might be avoided and might cause postoperative disability. Current literature does not describe the effect of variation in the spinal accessory nerve in the upper neck. We sought to measure the effect of the dimensions of level IIB on nodal yield in level IIB and on patient reported neck symptoms. Methods: We measured the boundaries of level IIB of 150 patients undergoing neck dissection. Level II was dissected and separated into levels IIA and IIB intraoperatively. Patient‐reported symptoms were assessed in 50 patients using the Neck Dissection Impairment Inventory. We computed descriptive statistics, and sought to identify correlation with the number and proportion of level IIB nodes and the number of metastatic nodes. Level IIB dimensions were analyzed as predictors of postoperative symptoms. Results: We measured 184 sides, with 37.7% of level II nodes found in level IIB. Mean accessory nerve length across level II was 2.5 cm. Every additional 1 cm in accessory nerve length was associated with two more level IIB nodes. At all accessory nerve lengths, meaningful numbers of nodes were present in level IIB. Accessory nerve length and other factors did not correlate with NDII scores. Conclusions: Longer lengths of accessory nerve across level IIB correlated with greater nodal yield. However, data did not point to an accessory nerve length cutoff below which level IIB dissection could be avoided. In addition, the dimensions of level IIB did not correlate with postoperative neck symptoms. Level of Evidence: 2 Laryngoscope, 134:154–159, 2024 [ABSTRACT FROM AUTHOR]

Abstract

Objective: Behcet's syndrome (BS) is a chronic, relapsing multisystemic inflammatory perivasculitis and can affect any tissue, including the nervous system. Neuro-Behcet's syndrome (NBS) most commonly affects the CNS parenchyma and presents with a subacute brainstem syndrome that includes cranial neuropathies. Here we describe a rare case of palato-pharyngo-laryngeal myoclonus as a manifestation of NBS and discuss it from a laryngology perspective. Methods: Case report at tertiary care center. Informed consent was obtained from patient. IRB approved as non-human subjects research. Results: A 52-year-old male presented with a progressive history of ataxia, fatigue, apathy, dysphagia, depressed mood, dizziness, poor appetite, subjective fever and recurrent orogenital lesions. He was diagnosed with NBS and treated with methylprednisolone, followed by infliximab and methotrexate. Despite treatment, his severe spastic dysarthria, dysphagia, and aspiration worsened over the next few months, necessitating a gastrotomy tube. With concern for laryngospasm, he was referred to otolaryngology and found to have synchronous and symmetric palatal, pharyngeal, and laryngeal rhythmic myoclonus bilaterally at a frequency of 2 Hz with inappropriate vocal cord closure. Treatment with baclofen and a scopolamine patch improved his breathing and reduced choking events. Conclusions: Palato-pharyngo-laryngeal rhythmic myoclonus can be a presentation of brainstem NBS in the otolaryngology clinic. We theorize perivascular disease in NBS results in a brainstem lesion in the denato-rubro-olivary tract, which results in hypertrophic olivary degeneration and subsequent activation of the inferior olives oscillatory activity, causing palato-pharyngo-laryngeal rhythmic myoclonus. Common symptoms include significant dysarthria, dysphonia, and dysphagia with concern for obstructive sleep apnea and airway compromise. Treatments include pharmacologic therapy, laryngeal botox, and tracheostomy in cases of significant airway compromise. [ABSTRACT FROM AUTHOR]

Titze (a), Henry T. Hoffman (a ) Keywords: Excised larynx; Cricoarytenoid joint; Rigid body mechanics Abstract: Summary: Rotational and translational stiffnesses were calculated for arytenoid motion about the cricoarytenoid joint. These calculations were obtained from measurements on five excised human larynxes. For each larynx, known forces were applied to the arytenoid cartilage, and three markers were tracked as a function of applied forces. Assuming rigid body motion, arytenoid translations and rotations were computed for each applied force. Translational stiffnesses were obtained by plotting force versus displacement, and rotational stiffnesses were calculated by plotting torque versus angular rotation. A major finding was that the translational stiffness along the anterior-posterior direction was three times as great as the translational stiffnesses in the other two directions. This nonisotropic nature of the stiffnesses may be an important consideration for phonosurgeons who wish to avoid subluxation of the cricoarytenoid joint in patients. The computed rotational and translational stiffnesses currently are being implemented in 2D and 3D models. These stiffness parameters play a vital role in prephonatory glottal shaping, which in turn exerts a major influence on all aspects of vocal fold vibration, including fundamental frequency, voice quality, voice register, and phonation threshold pressure.
