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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

The grading system of the severity of obstructive sleep apnea hypopnea syndrome (OSAHS) used presently showed that the severe OSAHS had an extensive range of apnea hypopnea index (AHI) (≥30, even over 100). So this grading system is not rational. From Jan 1999 to June 2011, there were 2,618 patients complaining of snoring took the polysomnography. The patients were divided into 11 groups according to their AHI. Frequencies of OSAHS with hypertension in each group were tested using crosstabs. The incidence of hypertension was increased as the increasing of AHI. Crosstab analysis showed that there were four cutoff points of AHI (5, 30, 50, 100). There was a significant difference in the incidence of hypertension between the groups of AHI more than the cutoff point and AHI less than the cutoff point. So from the view of hypertension in each group, we recommend that the AHI <5 should be considered as normal or simple snorer, AHI = 5–30 as mild degree of OSAHS, AHI = 30–50 as moderate degree of OSAHS, AHI = 50–100 as severe degree of OSAHS, and AHI ≥100 as profound degree of OSAHS. 相似文献

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. 相似文献

Occurrence of professional dysphonia was analysed in a group of 309 patients treated in the Phoniatric Outpatient Clinic, Department of Otolaryngology, Medical Academy in Bia?ystok through the period of 1999-2001. In a group of professional voice users female teachers of primary schools and lower secondary schools predominated. Obtained results were compared with those from a group of 65 persons of other occupations. In the both groups other harmful factors affecting the voice organ were excluded. The clinical assessment included subjective and objective laryngological examination using videolaryngostroboscopy. The clinical material was evaluated in a view of functional and organic disorders of the voice organ. Early occurrence and aggravation of functional changes in the larynx was recorded in non professional voice users in the course of their seniority. In professional patients organic changes were more common and occurred earlier than functional disorders. Severity of dysphonia was related to the larynx pathology, especially of a functional character. 相似文献

OBJECTIVE: The rate of false passages during probing for congenital nasolacrimal system obstruction (CNLO) is a major limiting factor for a successful outcome. This shortcoming may be decreased with the use of a nasal endoscope during probing. This approach is particularly important in the probing training of ophthalmology residents. METHODS: An experienced pediatric ophthalmologist performed probings on 11 eyes, and a group of ophthalmology residents under his supervision performed probings on another 11 eyes for CNLO. Their claims of a successful or unsuccessful procedure were evaluated with nasal endoscopy by an ear--nose--throat (ENT) surgeon. The age range of the patients was 8-23 months. RESULTS: The ophthalmologist made two false passages, one of which he was aware, out of 11 eyes. The residents had five false passages, two of which were unclear to them, out of another 11 eyes. No false passages occurred in obstructions at the level of the Hasner valve. None of the successful probings required more than a 30 mm probe introduction into the nasolacrimal canal from the inferior punctum. CONCLUSION: It seems justified to have a nasal endoscopic evaluation, performed by an ENT surgeon, for probings during the training program of ophthalmology residents. Difficult cases with stenosis proximal to the inferior meatus, prior false passage experience on a particular case, and any indication for silicone tube implantation will benefit from the use of an endoscope during the procedure. In order to achieve the best results in CNLO, the collaborative teamwork of an ophthalmologist and an ENT specialist is necessary. 相似文献
