Purpose: The aim of this study was to assess a non-endoscopic transoral versus extraoral technique in the open reduction and internal fixation of displaced or dislocated fractures of the condylar neck.
Material And Methods: A total of 104 patients, treated from 2007 to 2012 with 114 class II or class IV fractures according to Spiessl and Schroll were included in this study. Facial nerve function, scarring, pain and functional clinical parameters, such as protrusion, mediotrusion and maximum interincisal distance, were judged clinically (at 21 ± 12.1 months); repositioning and reossification were measured upon preoperative, postoperative and follow-up (at 8.8 ± 7 months) radiographs. Patient satisfaction was evaluated using the OHIP-G 14 questionnaire.
Results: In all, 36 patients (35%) with 43 fractures (38%) presented for clinical follow-up. Both treatment groups showed clinically and radiologically comparable results. Scarring was obvious in all extraorally treated patients, and hypertrophic scars occurred in four class IV cases (24%). One class IV patient (6%) had a persistent facial nerve palsy; temporary pareses were more frequent (n = 4; 24%).
Conclusion: The transoral approach did not jeopardize facial nerve function, and extraoral scars were avoided. Repositioning and fixation results and the frequency of revision operations were comparable. The transoral approach can be recommended generally in class II and class IV cases.

Background: Bell's palsy (BP) is a cranial nerve disorder in which unilateral or bilateral paralysis of the facial nerve occurs. The study aims to study BP's characteristics, including its clinical manifestations, prognosis, and complications among adult patients aged 18 years and above.
Methods: A retrospective study of adult patients diagnosed with BP in a primary care setting] [January 2015 to December 2022].

Introduction: Pediatric temporal bone fractures (TBFs) can result in adverse outcomes including meningitis, significant sensorineural hearing loss requiring cochlear implantation (CI), facial nerve weakness, cerebrospinal fluid (CSF) leak, and labyrinthitis. The objective of this study is to determine the risks of these outcomes for TBFs with hearing loss.
Methods: Using the multinational TriNetX database, a retrospective cohort study was performed of patients less than 18 years old with diagnostic codes for other fracture of base of skull and hearing loss to serve as an approximation of TBF.

Purpose: To assess the impact of retrograde dissection of the facial nerve along the mandibular margin on the postoperative quality of life in patients with benign superficial parotid tumors.
Methods: One hundred and sixteen patients who underwent surgical treatment for benign superficial parotid tumors at Qingdao Central Hospital from January 2020 to January 2023 were involved. The patients were randomly allocated into two groups, with 58 patients in each group using the touch ball method.
Characterization of Tip Fold-Over Using Fluoroscopy and Intracochlear Pressure in Cadaver Specimens.

Department of Otolaryngology, University of Colorado School of Medicine, Aurora, Colorado, U.S.A.
Objectives: Cochlear implant array malpositioning is associated with impaired speech perception, vertigo, and facial nerve stimulation. Tip fold-over is a subset of malpositioning that occurs more often with perimodiolar electrodes, but historically it has not been characterized due to lack of knowledge regarding electrode movements of the electrode within the cochlea. The aim of this study was to characterize the mechanics of tip fold-over events and their associated insertion pressure profiles.

Hemifacial spasm (HFS) is a disorder that causes involuntary movements of the ipsilateral facial muscles because of vascular compression of the facial nerve. Microvascular decompression (MVD), a surgical procedure to detach the culprit vessel from the nerve is believed to be the most effective treatment for HFS. Nevertheless, in the rare case in which the vessel penetrates the nerve, positioning the vessel sufficiently far from the nerve is challenging.
