“…In each case, the diagnosis of UVFP and the side of paralysis was confirmed using transnasal flexible endoscopy. We examined the relationship between thyroid, cricoid, and arytenoid cartilages by performing computed tomography (CT), including three-dimensional (3D) CT [20][21][22][23][24][25][26]. Following a comprehensive evaluation and examination of CT, 3DCT, and nasal endoscopy findings, we confirmed that there was no dislocation or trauma to the arytenoid cartilage.…”

The association between swallowing function and cough strength in patients with unilateral vocal fold paralysis (UVFP) is unknown. We evaluated the relationship between voluntary cough strength and dysphagia among patients with UVFP (UVFP group) by comparing their data with that of corresponding healthy participants (healthy control [HC] group) in a prospective observational study. From February 1st, 2018 to March 30th, 2019, we recruited patients with a voice disorder due to UVFP, who were referred to our university hospital. Patients with a history of laryngeal surgery, vagal nerve paralysis, or cardiac and respiratory failure were excluded. Descriptive and clinical data regarding swallowing, voice, and cough peak flow (CPF) were collected as a measure of cough strength. The UVFP group comprised six women and seven men (median age, 68.0 years), and the HC group comprised six women and eight men (median age 65.5 years). The groups differed significantly in the Eating Assessment Tool (EAT)-10 scores and CPF rates (P < 0.001). Among patients with UVFP, 84.6% had an abnormal EAT-10 score of ≥ 3. Additionally, 16.7% of the patients exhibited liquid aspiration with contrast medium on a videofluorographic swallowing study (VFSS). There was no correlation between the CPF values, EAT-10 scores, or the VFSS results. Therefore, patients with severe UVFP, whose condition had been fixed, had difficulties when swallowing (85% of cases), and some even presented with aspiration on VFSS (20% of cases), while receiving a regular diet.

“…Autologous tissue, allogeneic, artificial materials and tissue engineering technology were utilized to repair and reconstruct laryngeal cartilage damage [3]. At present, natural macromolecule biomaterials, synthetic polymer materials, bioceramic materials and composites have been the primary materials for tissue engineering scaffolds [4][5][6][7][8]. Natural biological materials possess excellent adhesion for cells, hydrophilicity and compatibility, which include gelatin, sodium alginate, collagen, chitosan, and fibrin gels.…”

Abstract. Due to the limitation of self-repairing capability for cartilage injury, the construction of tissue engineering in vitro has been an ideal treatment to repair tissue injury. In this paper, hydroxyapatite (Hap) and chitosan (Chi) were selected to fabricate the scaffold through low temperature deposition manufacturing (LDM) technique. The scaffold was characterized with interconnected structure and high porosity, as well as lower toxicity to cells (TDC-5-EGPE). Animal experiment was performed, Twelve white New Zealand rabbits were randomly divided into two groups, the side of the thyroid cartilage was removed, Chi-HAP composite scaffold was implanted into the cartilage defect as the experimental group A. Group B was treated for thyroid cartilage defects without any treatment. After 10 weeks, hematoxylin-eosin(HE) staining and S-O staining were carried out on the injured tissues. The result showed that newborn chondrocytes were found in repaired areas for group A, and there are no new cells found for group B. Therefore, Chi-HAP composite scaffolds formed by LDM possess biological activity for repairing injury cartilage.

“…Cricoarytenoid joint subluxation is a rare lesion with less than 200 cases described in the literature [1]. The exact incidence of this condition is unknown because the immobility of the vocal fold may be confused with vocal fold palsy, therefore it is believed that the actual incidence is being underestimated [2,3].…”

Cricoarytenoid joint subluxation is rare condition. There are \200 cases reported in the English literature. The most frequent cause of this condition is a traumatic tracheal intubation which account for approximately 80 % of all cases. The most common symptoms are dysphonia and pain of the anterior region of the neck which appear after upper airway manipulation or cervical trauma. In this report we present a well-documented case of a 31 year old male that was referred to the outpatient clinic because of acute dysphonia and pain that appeared immediately after receiving a blow of a soccer ball. Diagnosis was suspected after patient reported the acute onset of symptoms after the traumatic event along with findings in flexible fiberoptic laryngoscopy and videostroboscopy. A CT scan of the larynx was done where the injury of the left cricoarytenoid joint was seen. The patient was informed of the condition and was given the option of surgical reduction or speech therapy. Speech therapy was done for 3 month and the patient was satisfied with the result, although the anatomical abnormality persisted. We reviewed the literature and we discuss the diagnosis process and possible treatment options.
