Objective assessment of the severity of unilateral facial palsy using OKAO Vision® facial image analysis software

Vestibular compensation is defined as the process of behavioural recovery that occurs following the loss of sensory input from one or both vestibular labyrinths. The visual and postural instability resulting from the vestibular damage must alter the homeostasis of the subject; however, very little research has been conducted that investigates the interaction between vestibular compensation and the adaptive stress response of the body, i.e. the hypothalamic—pituitary—adrenal (HPA) axis. The aim of this review is to describe and evaluate the experimental evidence indicating a link between vestibular compensation and the body's response to stress, via the HPA axis.     

Experiencing tinnitus: which factors are important for perceived severity of the symptom?

This study attempted to determine those factors important for predicting the experienced severity of tinnitus. For this purpose, we examined affected patients' perception of tinnitus as an illness, comorbidity, scores on locus of control, length of time since onset of tinnitus, pitch and loudness of tinnitus sounds, and depression. One hundred and forty-nine patients (72 women, 77 men) experiencing chronic tinnitus participated in our study. An ordinal logit regression analysis showed that depression and loudness of tinnitus sounds were the best predictors of perceived severity of tinnitus and were followed in importance by the internal locus of control. In contrast, the patients' perception of tinnitus as an illness and comorbidity had no predictive value on the severity of tinnitus. These findings underscore the predominant role of depression, loudness of tinnitus, and internal locus of control in patients with tinnitus and provide an overview of relevant factors concerning tinnitus described in studies to date.     

Measuring the density of the fissula antefenestram and the section of the basal turn of the cochlea: Are they useful in the radiological diagnosis of otosclerosis?

IntroductionThe role of objective parameters in terms of improvement of the accuracy of high-resolution computed tomography (HRCT) of the temporal bone in the diagnosis of otosclerosis remains unclear.ObjectivesTo investigate the relationship between the density of the fissula antefenestram (FAF) and of the width of the transversal section of the basal turn of the cochlea (BTC), and the diagnosis of otosclerosis.MethodsThis is a retrospective study in which preoperative HRCT data from ears of patients submitted to stapedotomy due to otosclerosis (case group) were evaluated. For the control group, normal hearing ears having undergone HRCT for other purposes were included. Case and control HRCT images were objectively assessed by an experienced blinded radiologist. During this evaluation, measurements of the relative radiological density of the FAF and of the transversal section of the BTC were obtained. The results were compared between the groups. Also, a receiver operating characteristic curve was created and the area under the curve (AUC) was calculated for each variable. Significance level was set at .05.Results40 ears were included in each group. Case ears presented reduced values for the relative radiological density on the FAF (p-value<0.0001). Moreover, ears with otosclerosis (p-value: 0.022) presented lower transversal section of the BTC. The AUC for these variables reached 0.929 and 0.646, respectively.ConclusionsOtosclerotic ears present reduced radiological density on the FAF and narrower BTC. The relative density of the FAF also shows a great diagnostic power in the context of this disease.     

Are corticosteroids useful in all degrees of severity and rapid recovery of Bell’s palsy?

Conclusions The results provide preliminary evidence that corticosteroids were not effective in all grades of dysfunction and for achieving a rapid remission in the early phase of BP, highlighting the need to define standard and rigorous criteria to prescribe corticosteroids in these patients. Objectives The main aim of this study was to investigate whether the use of corticosteroids better associated than paralleled with neuromuscular training (C?+?FNT) is more effective than facial neuromuscular training (FNT) applied alone, in terms of recovery degree and facial symmetry during the early phase of Bell’s palsy (BP). Patients and methods A prospective single-blinded study involved 73 patients: the C?+?FNT group (n?=?42; median age = 37.5 years) and FNT group (n?=?31; median age = 49.0 years). Patients were assessed before and 6 weeks after treatment by House-Brackmann (HB-FGS) and Sunnybrook Facial Grading System (SB-FGS). Results Recovery degree and facial symmetry improved significantly in both groups (p?p?>?0.05). However, the C?+?FNT group displayed better outcomes for cheek (p?=?0.004) and mouth (p?=?0.022) resting symmetry at SB-FGS, instead of compared to the FNT group. The corticosteroids had no significant effect on all recovery degrees (p?=?0.992) and rapid remission (p?=?0.952). Multiple linear regression analysis showed that the type of intervention was not a significant predictor for recovery degree (p?=?0.917).     

Pleomorphic adenomas in the materials of the Department of Otolaryngology of the Academy of Medical Sciences in Poznań

In the years 1958-1997 were surgically treated in the Department of Otolaryngology Karol Marcinkowski University of Medical Sciences in Poznań 365 patients with pleomorphic adenomas. Majority of the tumors originated of the major salivary glands was parotid gland (273 cases). The given materials confirms the viewpoint that enucleation in the pleomorphic adenomas of the parotid salivary gland--based on total removal of the tumor together with the capsule and pouch constitute a completely sure surgical procedure.     

Comparison of the application methods and effects of skin flaps in the repair of defects in different parts of the nose according to the concept of aesthetic nosesubunits北大核心CSCD

Objective To analyze the difference of application methods and effects of local flap in small and medium‑sized defects of different aesthetic subunits of nose, in order to provide reference for clinical work. Methods A retrospective analysis was made on 59 patients with external nasal masses and scars who underwent surgical treatment in the Department of Aesthetic Plastic Surgery of the Affiliated Hospital of Qingdao University from July 1, 2021 to January 30, 2022, including 27 females and 32 males, aged 15 to 69 years. Using Likert scale, the repair methods and effects of local flap for nasal soft tissue defects were evaluated and summarized from three aspects of texture, flatness and scar concealment. GraphPad Prism 5.0 software was used for data statistics and analysis. Results The use of skin flaps to repair small and medium‑sized areas of the nose could achieve satisfactory results. For patients with different subunits, in terms of skin flatness and scar concealment degree in the operation area, patients′ satisfaction with the dorsal and lateral nasal areas was higher than that of the alar and tip areas, respectively (F=6.40, P=0.001; F=10.57, P<0.001). For patients with different skin flap repair methods, the satisfaction of patients with Z‑plasty and Dufourmentel skin flap was higher than that of other skin flap repair methods (F=4.38, P=0.002), and the satisfaction of patients with Dufourmentel skin flap was the highest in the degree of scar concealment (F=2.57, P=0.038). Conclusions In the small and medium‑sized defects of the nose, the use of multiple local flaps can achieve good cosmetic effects and functional recovery. The operator should select the appropriate flap repair method according to the characteristics of different aesthetic subunits of the nose. © 2023 Authors. All rights reserved.     

Is the Trachea a Marker of the Type of Environmental Pollution?

OBJECTIVES/HYPOTHESIS: The differentiated character of changes in the mucous relief of the trachea as induced by air containing pollutants from the wastes of nickel-, mercury-, and cement-producing plants and by Candida albicans occurring in the waste disposal site of a large town are identified. The trachea was chosen because it is the entrance gate for the penetration of polluted air into the lungs. Changes on the trachea influence the character and extent of changes in lungs. STUDY DESIGN: Histological study with Viennese grey strain laboratory rabbits and rats caught directly on an investigated site. METHODS: We present new results of the functional morphology of the respiratory system as the results of scanning and transmission electron microscopy studies that can reveal character and range of damage of mucosal relief of trachea relevant to the functional dynamics of mucociliary clearance. Under physiological conditions this mechanism allows that only respirable dust particles enter the deep respiratory tract. RESULTS: In case of a damaged tracheal relief because of exposure to various aerosols, the functional morphology is changed, which aids in understanding the mechanisms damaging to mucociliary clearance induced by living in heavily polluted areas. CONCLUSION: Understanding of these morphological changes on base of detailed electron microscopic findings sheds new light on elaborating novel diagnostic methods for clinical practice.     

The causes of the development of cicatrical stenosis of the larynx and trachea in the patients presenting with Guillain-Barré syndrome

The problem of rehabilitation of the patients presenting with post-intubation stenosis of the larynx and trachea remains unresolved despite the development of new methods for the diagnostics and treatment of this condition. One of the indications for long-term artificial lung ventilation is the severe form of Guillaine-Barret syndrome associated with paralysis of breathing muscles, development of bulbar symptoms, and disturbances of trophic process in the skin and mucous membranes. However, prolonged (mean 26 days) artificial lung ventilation may result in the formation of many-layer stenosis of the larynx and trachea whereas disturbed trophic processes in the skin and mucous membranes coupled to inadequate innervation complicate the postoperative conditions of the patients and promote restenosis of the tracheal lumen.
