Unilateral Vocal Cord Paralysis

Unilateral vocal cord paralysis (UVCP) is relatively common, and previously, thyroidectomy used to be the leading cause. We retrospectively reviewed 98 cases of UVCP. The left vocal cord was involved in 70% of the cases and the right vocal cord in 30%. The cause was neoplastic in 32%, surgical in 30%, idiopathic in 16%, traumatic in 11%, central in 8%, and infectious in 3% of the cases. Only 4 cases were the result of thyroid surgery. Evaluation consisted of a review of the history, a physical examination, and computerized scanning or magnetic resonance imaging, as needed. The functional recovery rate as related to the cause was as follows: surgery 31%, idiopathic 19%, traumatic 18%, and neoplastic 0%. Thirty-five percent of patients required medialization Iaryngoplasty or Teflon injection. Lung and skull base tumors and their surgical treatment are the most common causes of UVCP.

Introduction: The presentation, course, and management of a rare laryngeal manifestation of neurosarcoidosis due to central nervous system (as opposed to peripheral nervous system) injury are described. Methods: The authors present 3 cases of vocal cord paralysis as the initial symptom of isolated neurosarcoidosis at a tertiary care laryngology clinic. Results: Laryngoscopy diagnosed unilateral vocal cord paralysis. Laryngeal electromyography revealed high vagal injury, prompting workup on brain magnetic resonance imaging. On magnetic resonance imaging, 2 cases showed basilar leptomeningeal inflammation and 1 case showed a brainstem mass. Patients were found at follow-up to have severe, progressive vagal injury, with patients developing severe quality of life impairments and medical complications. Conclusions: Neurosarcoidosis is not usually considered in the differential diagnosis of vocal cord paralysis. At initial presentation, all patients lacked other cranial neuropathies and systemic sarcoidosis manifestations, making diagnosis difficult. Otolaryngologists should be aware of this rare presentation, as prompt diagnosis by brain magnetic resonance imaging with or without central nervous system biopsy, as opposed to traditional chest radiography or computed tomography for the workup of peripheral nerve injury, is necessary. Serial laryngeal examinations are recommended for close monitoring of progressive disease and recommending treatment. Injection or medialization laryngoplasty can provide improvements in voicing but not swallow.

The aim of the review was to summarize information on clinical manifestations, diagnostic features, as well as methods for correction of scar defects after cesarean section (CS) outside pregnancy. Lack of the scar after CS, niche, isthmocele are a myometrium defect in the area of scar after CS, which is most often detected by ultrasound, sonohysterography or magnetic resonance imaging and is manifested by postmenstrual bleeding from the genital tract. In some cases, it can cause menorrhagia, dyspareunia, pelvic pain, infertility, uterine rupture during subsequent pregnancy and childbirth. Conservative therapy or surgical treatment with laparoscopy, laparotomy or vaginal approach is carried out depending on the symptoms, size of the defect, the thickness of the residual myometrium, as well as the womans reproductive plans.

Purpose: The aim of this study was to assess the volumetry of the hippocampus in the Leber’s hereditary optic neuropathy (LHON) of blind patients. Methods: A total of 25 patients with LHON were randomly included into the study from the national health database. A total of 15 patients were selected according to the inclusion criteria. The submillimeter segmentation of the hippocampus was based on three-dimensional spoiled gradient recalled acquisition in steady state (3D-SPGR) BRAVO 7T magnetic resonance imaging (MRI) protocol. Results: Statistical analysis revealed that compared to healthy controls (HC), LHON subjects had multiple significant differences only in the right hippocampus, including a significantly higher volume of hippocampal tail (p = 0.009), subiculum body (p = 0.018), CA1 body (p = 0.002), hippocampal fissure (p = 0.046), molecular layer hippocampus (HP) body (p = 0.014), CA3 body (p = 0.006), Granule Cell (GC) and Molecular Layer (ML) of the Dentate Gyrus (DG)–GC ML DG body (p = 0.003), CA4 body (p = 0.001), whole hippocampal body (p = 0.018), and the whole hippocampus volume (p = 0.023). Discussion: The ultra-high-field magnetic resonance imaging allowed hippocampus quality visualization and analysis, serving as a powerful in vivo diagnostic tool in the diagnostic process and LHON disease course assessment. The study confirmed previous reports regarding volumetry of hippocampus in blind individuals.

Unilateral Vocal Cord Paralysis

Five cases of unilateral vocal cord paralysis/ paresis were diagnosed following extracorporeal membrane oxygenation for newborn respiratory failure. All were right sided and transient in nature. None of the five patients had other findings commonly associated with vocal cord palsy. The extracorporeal membrane oxygenation procedure requires surgical dissection in the carotid sheath on the right side of the neck, an area immediately adjacent to both the vagus and recurrent laryngeal nerve. It is speculated that vocal cord paralysis in these infants was acquired as a result of the extracorporeal membrane oxygenation cannulation. Although the vocal cord paralysis resolved in all cases, two patients had difficult courses after extracorporeal membrane oxygenation. Therefore, laryngoscopic examination should be considered for patients after extracorporeal membrane oxygenation.

Background: Pure epidural spinal cavernous hemangiomas (SCH) account for only 4% of all spinal epidural lesions. Our literature review identified 61 publications reporting on, a total of 175 cases in the magnetic resonance imaging era. Here, we reviewed those cases, and have added our case of what appeared to be a multifocal SCH. Case Description: A 72-year-old male presented with a progressive paraparesis attributed to a T5/T6 dorsolateral extradural mass extending into the right T5/6 foramen. Surgical excision documented the lesion, histologically, was a SCH. A second similar lesion was noted involving the left C7/T1 foramen; as the patient was asymptomatic from this lesion, and no additional biopsy was performed. The patient returned to normal neurological function within 2 months postoperatively. Conclusions: Here, a 72-year-old male presented with a pathologically confirmed T5/T6 epidural SCH and a secondary C7/T1 foraminal lesion suspected to represent a secondary focus of an epidural SCH.
