xlomafota13 shared this article with you from Inoreader A Tissue Engineered Construct for Laryngeal Regeneration: A Proof‐of‐Concept Device Design Study Via The Laryngoscope Objectives/Hypothesis Develop a patient-specific tissue engineered construct for laryngeal reconstruction following a partial laryngectomy. Study Design Bench and animal research. Methods A construct made from a porous polyethylene scaffold shaped in a canine-specific configuration and seeded with autologous canine adipose-derived stem cells in fibrin glue was implanted in a canine following a partial laryngectomy. After 1 year, the construct was first evaluated in vivo with high-speed imaging and acoustic–aerodynamic measures. It was then explanted and evaluated histologically. Results The canine study at 1 year revealed the construct provided voicing (barking) with acoustic and aerodynamic measures within normal ranges. The canine was able to eat and breathe normally without long-term support. The construct was integrated with epithelialization of all areas except the medial portion of the vocal fold structure. No anti-infective agents were needed after the standard perioperative medications were completed. Conclusion This study provided a successful first step toward developing a patient-specific composite construct for patients undergoing partial laryngectomies.

xlomafota13 shared this article with you from Inoreader The music-related quality of life: Italian validation of MuRQoL into MUSQUAV questionnaire and preliminary data from a cohort of postlingually deafened cochlear implant users Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Jan 28. doi: 10.1007/s00405-022-07258-1. Online ahead of print. ABSTRACT PURPOSE: Cochlear implant (CI) users do not receive much of the auditory information necessary for an accurate perception of music. This usually entails a dissatisfaction with the music they hear, so that their quality of life may potentially be affected. The main aim of this paper was to translate and validate into Italian an instrument to evaluate these aspects-The Music-Related Quality of Life Questionnaire (MuRQoL)-to help the work of clinicians and therapists. METHODS: The translation of the MuRQoL into "Questionario Musica e Qualità della Vita" (MUSQUAV) was done according to the international guidelines. The translated questionnaire was administered to normal hearing (NH) and CI users adults. Exploratory factor analysis, confirmatory factor analysis and known group method were used to confirm construct validity and app licability of MUSQUAV. RESULTS: We retrieved 225 results. The MUSQUAV questionnaire was acceptable according to the goodness-of-fit indices. The correlation between the items, evaluated using Cronbach's α coefficient, indicates a good internal consistency (> 0.80). The non-parametric Mann-Whitney test showed significant differences in the distinct populations tested. CONCLUSIONS: The MUSQUAV questionnaire is a valid, low-cost and rapid instrument for professional workers in the audiological field, especially useful in the assessment of the patients' perception and musical engagement.

Intraoral Approach for Parapharyngeal Branchial Cleft Cysts

xlomafota13 shared this article with you from Inoreader Intraoral Approach for Parapharyngeal Branchial Cleft Cysts Via ear nose throat Ear Nose Throat J. 2022 Jan 28:1455613211067846. doi: 10.1177/01455613211067846. Online ahead of print. ABSTRACT Branchial cleft cyst (BCC) most frequently arises from the second branchial cleft and is located anterior to the sternocleidomastoid muscle at the mandibular angle. However, very rarely, this may occur in the parapharyngeal space. Interestingly, the parapharyngeal BCC is frequently misdiagnosed as a peritonsillar abscess. In this study, we reported 2 cases of para pharyngeal BCC misdiagnosed as peritonsillar abscess. PMID:35088618 | DOI:10.1177/01455613211067846 View on the web Inoreader.

Evaluation of chemosensory function in patients with upper respiratory tract post-viral olfactory dysfunction

xlomafota13 shared this article with you from Inoreader Evaluation of chemosensory function in patients with upper respiratory tract post-viral olfactory dysfunction Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2022 Jan 7;57(1):29-35. doi: 10.3760/cma.j.cn115330-20210331-00163. ABSTRACT Objective: To observe the changes of olfactory function, intranasal trigeminal nerve function and taste function in patients with upper respiratory tract post-viral olfactory dysfunction (PVOD), and to explore the correlation of chemosensory function. Methods: The clinical data of 42 patients with PVOD who visited to the Olfactory and Taste Center of Otorhinolaryngology Head and Neck Surgery Department of Beijing Anzhen Hospital from January to December of 2019 were analyzed retrospectively, including 20 males and 22 females, aging (48.86±11.47) years (x¯). Twenty subjects in normal control group were selected according to the sex ratio of PVOD patients. Sniffin' Sticks olfactory tests were performed on the subjects, including threshold test (T), discrimination test (D) and identification test (I), and the sum of the above three test scores was the TDI value. At the same time, olfactory event-related potentials (oERPs), trigeminal event-related potentials (tERPs) and taste function test were performed. According to the taste function test, the patients were divided into normal gustation (NG) group and gustatory dysfunction (GD) group. The results of olfaction, taste and intranasal trigeminal nerve function tests were compared among different groups, and the correlation analysis was carried out. SPSS statistical software was used for statistical analysis. Results: GD was present in 14 (33.3%) of 42 PVOD patients with a course of PVOD of 5 (3, 6) months (M (Q1, Q3)). The gustatory function of patients with PVOD was related to gender (r=0.565, P<0.001), smoking status (r=-0.512, P=0.001), duration (r=-0.357, P=0.020) and olfactory function (all P<0.05). The olfactory function of GD group was worse than that of NG group, and the differences of TDI value and T value between the two groups were statistically significant (10.25±4.58 vs 13.35±3.61, 1.54±0.66 vs 2.10±0.88, t value was 2.40 and 2.10 respectively, both P<0.05). The amplitudes of oERPs and tERPs were significantly lower in GD group than those in NG group (all P<0.05). Conclusion: In patients with PVOD, the subjective and objective olfactory function, intranasal trigeminal nerve function and taste function were decreased, and there was a correlation, suggesting that there was a synergistic effect between the chemosensory functions of PVOD patients.

The importance of systemic immune-inflammation index in obstructive sleep apnea syndrome

xlomafota13 shared this article with you from Inoreader The importance of systemic immune-inflammation index in obstructive sleep apnea syndrome Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Jan 29. doi: 10.1007/s00405-021-07227-0. Online ahead of print. ABSTRACT OBJECTIVE: This study aims to explore the importance of systemic immune-inflammation index (SII) in patients diagnosed with obstructive sleep apnea (OSA). MATERIALS AND METHOD: In this study planned as a retrospective cohort, the files of the patients who presented with sleep apnea/snoring complaint between 10.01.2017 and 10.01.2021 and underwent polysomnography (PSG) and complete blood count analyses were reviewed. PSG findings (age, sex, body mass index (BMI), apnea-hypopnea index (AHI), mean oxygen saturation) were compared with SII in 194 patients meeting study eligibility criteria. RESULTS: Patients included in this study were divided into 4 groups by AHI value. Statistical difference was detected between the groups in terms of age, sex, body mass index (BMI), and mean oxygen saturation (p < 0.05). There is an ap proximately 30% positive statistically significant correlation between the severity of OSA and SII (p < 0.001). As for the mean SII values of the AHI groups, it was observed that the more severe AHI is, the higher the mean SII value is. The correlation between SII and the severity of OSA was found to be more significant than the correlation with neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR). CONCLUSION: There is a significant correlation between SII and the severity of OSA. This correlation is stronger compared to NLR and PLR. SII can be used to demonstrate the chronic systemic inflammation observed in OSA patients, and can be utilized as a simple and inexpensive biomarker as it can be easily calculated from the parameters present in routine blood analyses.
