Abstract Background. The objective was to identify the risk factors for, and incidence of, facial palsy following conservative parotidectomy. Methods. Conservative parotidectomies for benign diseases ( N = 626) were studied retrospectively. postoperative determined by univariate multivariate analyses of variables related patient demographics, comorbid illnesses, characteristics operation. Results. rate transient palsies 23.16% Significant diabetic mellitus (odds ratio [OR] 1.727 [95% CI:...

Laryngeal neuroendocrine carcinomas (LNECs) are rare and highly heterogeneous which present a wide spectrum of pathological clinical manifestations. Fourteen patients with histologically demonstrated LNEC were collected analyzed retrospectively. The 14 cases classified into 3 subtypes: typical carcinoid in 2, atypical 5, small cell carcinoma 7. mean survival time the this study was 112.5 months (95% CI, 81.5–143.6). Surgeries performed for 2 carcinoid, they alive no evidence recurrence after...

The aim of the present study was to investigate effect glucocorticoid intervention on olfactory dysfunction in mice with allergic rhinitis (AR). An AR animal model established by intraperitoneal injection and intranasal application ovalbumin mice. function evaluated using a buried food test, morphological changes nasal mucosa were determined hematoxylin eosin staining. expression marker protein (OMP) tested immunohistochemistry, observed days 7 14 after glucocorticoid. incidence rate 75.34%,...

Bell's palsy is a commonly seen cranial nerve disease and can result in compromised facial appearance functions. Its etiology, prognosis treatment are still being debated. This paper review of recent development the understanding diagnosis non-surgical palsy.

The purpose of this study was to explore the effectiveness wideband acoustic immittance (WAI) in diagnosis otosclerosis by comparing differences energy reflectance (ER) WAI between patients with and age- gender-matched normal hearing controls Chinese population.Twenty surgically confirmed otosclerotic ears were included group. ER at ambient peak pressures, resonance frequency, 226-Hz tympanogram collected prior surgery using a Titan test platform (Interacoustics A/S, Middelfart, Denmark)....

Abstract Background To investigate the prognostic value of a three-dimensional dynamic quantitative analysis system to measure facial motion (3D ASFM) in acute palsy patients and compare it with subjective grading methods electroneurography. Methods We continuously recruited 37 (< 1 month) Bell’s palsy. An integrated evaluation was performed for each patient. The included House-Brackmann (H-BGS), Sunnybrook Facial Grading System (SFGS), electroneurography objective measurements. Then,...

Thalamic hemorrhage (TH) is a devastating disease with high mortality rate; however, no specific form of therapy has been proven to reduce mortality. Patients hemorrhagic stroke undergo intracranial pressure (ICP) monitoring. However, cases involving pseudoaneurysms caused by ICP monitoring in patients intracerebral have not reported previously. Here, we report case pseudoaneurysm an monitor that was fitted due hypertensive cerebral hemorrhage.

Background: A tumor deposit (TD) is a phenomenon that has not been well studied in head and neck squamous cell carcinoma (HNSCC) but might have prognostic significance. The present study was conducted to explore the presence significance of TDs patients with HNSCCs. Methods: Six hundred forty-two pathologically confirmed HNSCC dissection samples were enrolled this retrospective study. Patients followed up evaluated every 3 months first years after surgery, 6 thereafter by physical...

Objective: To measure movements of markers over the primary site and associated mimic muscles in certain facial expressions, for evaluating paresis synkinesis. Methods: Participants included 22 normal subjects aged 45–66 years. Maximum shift (Smax) velocity (Vmax) were measured using a custom-designed 3-D dynamic quantitative analysis system motion (3-D ASFM) based on capture technology. Measures taken from peri-oral during forceful brow raising tight eye closure, around grinning,...

This study was conducted to design new instruments solve the current issues of one-hand control and obscuring endoscope by blood during transnasal endoscopic surgery. An holder an electronically controlled irrigation-suction system were designed manufactured. The feasibility effectiveness operation models verified in a model surgery procedure performed on mongrel dog. During operation, one hand used perform move endoscope, other for irrigation suction keep surgical field clear. combined use...

Background Head and neck paragangliomas (HNPGLs) are rare neuroendocrine tumors that pose significant challenges in both diagnosis treatment. The pathogenic mechanism remains unclear, there is no proteomic analysis-based molecular classification. Therefore, gaining a deeper understanding of this disease from the protein level crucial because proteins play fundamental role occurrence development tumors. Methods We collected 44 tumor samples patients diagnosed with HNPGL. adrenal paraganglioma...

The selection of appropriate materials and techniques for reconstructing skull base defects is crucial restoring function, minimizing complications, enhancing aesthetics. Dermal fat grafts (DFGs) have been established in many surgeries contour correction. However, there little literature describing the application free dermal reconstruction lateral surgery defects. Therefore, aim this study was to evaluate clinical effect using

This study aims to discuss the necessity，surgical method and effect of reconstruction internal carotid artery （ICA） in resection paraganglioma head neck.

The current study summarized the surgical key points and technique advantages of endoscope holder in revision tympanoplasty. Fifteen patients who underwent tympanoplasty using between January 2023 April 2024 at Department Otorhinolaryngology, Peking Union Medical College Hospital were retrospectively collected. There 6 males 9 females, with an average age (37.1±13.4) years. All successfully completed under holder. median follow-up time was 8 months (range: 2-16 months). Postoperative...

Objective: To investigate the clinic feature, pathology, therapy and prognosis of sarcomatoid caricinoma or carcinosarcoma larynx. Methods: We reviewed clinical records 7 patients with laryngeal /sarcomatoid who were treated at our hospital between June 1996 August 2016. All men (mean age, 65.9 years; range, 52 to 94 years). Among patients, 6 had a history smoking; 2 underwent radiotherapy; 5 didn't undergo radiotherapy complained hoarseness. The glottis was most frequent site involvement....

Surgeons are continuing to strive toward achieving higher quality minimally invasive surgery. With the growth of modern technology, intelligent medical devices being used improve safety Milling beyond bone tissue wall is a common abnormal milling state in ear surgery, as well entanglement drill bit with cotton swab, which will do harm patient's encephalic tissues. Various methods have been investigated by engineers and surgeons an effort avoid this type during This paper outlines new method...

The aim of this study was to measure the facial motion patients with paralysis using a three-dimensional dynamic quantitative analysis system (3D ASFM) and analyze its correlation subjective grading systems.We included 30 healthy volunteers 50 unilateral paralysis.
