    Title translation Verschlucktes Gebiss im proximalen Ösophagus steckengeblieben.
    Abstract A 72-year-old male with dementia and Parkinson's disease presented at the otorhinolaryngology outpatient clinic with acute dysphagia. A chest x‑ray showed a dental prosthesis in the upper esophagus, which was subsequently extracted via rigid esophagoscopy. Due to suspected esophageal perforation on postoperative CT, a cervical approach to the esophagus and flexible esophagoscopy were used, but no evidence of perforation could be identified. This case highlights challenges in managing high-risk esophageal foreign bodies in the upper esophagus, emphasizing the need for careful assessment and a multidisciplinary approach.

    Abstract Patients with scala tympani (ST) ossification present a distinct surgical challenge. Three-dimensional (3D) segmentation of the inner ear offers accurate identification of ossification and surgical planning of the cochleostomy to access the scala vestibuli. The scala vestibuli placement of cochlear implantation electrode is an alternate solution in these patients and is well supported by the literature.The present report describes a case of cochlear implantation in the scala vestibuli assisted by 3D segmentation of the cochlea for a patient with ossification in the ST and reviews the relevant literature. Clinical presentation of a 45-year-old Austrian female who was referred with a history of sudden sensorineural hearing loss 2 years ago in the right ear, confirmed by pure tone audiometry (PTA) and acoustically evoked auditory brainstem response (ABR). 3D segmentation of the inner ear identified the extent of ossification in the ST and assisted in the surgical planning of cochleostomy drilling anterior-superior to the round window to access the scala vestibuli for the electrode placement. Postoperative computed tomography (CT) to confirm the electrode placement in the scala vestibuli and PTA was performed to assess the hearing threshold following the cochlear implantation. Postoperative CT confirmed the full insertion of a flexible electrode. The hearing threshold measured by PTA was ≤ 40 dB across all frequencies tested. Review of the literature identified a total of 13 published reports on cochlear implantation electrode placement in scala vestibuli in cases with ossification in the ST.

    Abstract Background: Septoplasties and septorhinoplasties are very commonly performed surgical procedures in modern aesthetic and functional medicine. Throughout the surgery, close manipulation to the incisive nerves' course is being executed. This retrospective analysis followed up on potential sensitivity disorders of the anterior palate due to nerve damage.
    Methods: This retrospective review of 2000 patients' charts, who had undergone the procedure of a septoplasty or septorhinoplasty between June 2013 and January 2019 was conducted at the Department of General Otorhinolaryngology, Medical University of Graz. Medical records of all included patients were reviewed with special attention to postoperative numbness of the anterior palate.
    Results: Among the 2000 included patients, a septoplasty was performed in 48% (n = 955), a septorhinoplasty in 35% (n = 703) and a septoplasty in combination with a functional endoscopic sinus surgery in 17% (n = 342). In total, 86% (n = 1721) showed no complications at all during the follow-up period. In 0.25% (n = 5) a sensitivity disorder of the anterior palate occurred. Of the five cases with a postoperative numbness of the anterior palate four occurred after a septoplasty and the fifth occurred following a septorhinoplasty.
    Conclusion: At this current time, this is the largest study investigating postoperative numbness of the anterior palate retracing septoplasty or septorhinoplasty. As a result, the currently used techniques for the operations do not pose a risk for the incisive nerve despite close surgical manipulation to the nerves' course. Nevertheless, patients should be informed and educated about the possibility of an occurring sensitivity disorder regarding the anterior palate during informed consent.

    Abstract Background: Sinonasal mucosal melanoma (SNMM) is a rare disease entity comprising 0.4-1.3% of all melanomas. Surgery with free margins has been the primary treatment over decades. Neither the addition of radiotherapy nor chemotherapy could significantly improve outcome rates of this devastating malignancy. This study presents our clinical experience with SNMM over a 19-year period and summarizes the current body of literature on SNMM.
    Methods: This retrospective analysis included 12 patients with SNMM treated from 2001 to 2019 at an academic center. Additionally, a literature review of the last 29 years on treatment and survival data of SNMM was conducted.
    Results: Main initial symptoms were epistaxis and nasal obstruction. Of the patients 9 underwent endoscopic surgery, 6 received adjuvant therapy. 3 patients who did not undergo surgery, received chemoradiotherapy, radiotherapy alone, and chemotherapy alone, respectively. At the time of diagnosis 2 patients had distant metastases and 4 patients developed distant metastases during the course of the disease. Mean overall survival (OS) was 30.6 months, 3‑year and 5‑year OS were 25%, and 18.2%, respectively.
    Conclusion: Unspecific symptoms and hidden anatomic locations lead to delayed diagnosis and increased rates of metastatic dissemination. Distant metastasis is the main treatment failure in SNMM. Surgery with free margins remains the primary treatment for SNMM. Adjuvant radiotherapy might improve local control in individual cases but efficient systemic therapy is needed to improve outcome rates. To evaluate and define more effective targeted treatment options and improve outcome rates, homogeneous data and prospective multicentric analysis are needed.

    Abstract The anterolateral thigh flap and the tensor fasciae latae flap are supplied by the lateral circumflex femoral artery (LCFA). Different branching patterns of the LCFA have been described, leading to confusion, discrepancies and difficulties in clinical and cadaveric study comparisons. The aim of this study was to evaluate the branching patterns of the LCFA in dissected lower limbs and propose a simplified nomenclature. One hundred and two lower limbs fixed with Thiel's method were investigated. Meticulous dissection was performed, and the branching pattern of the arteries was documented by illustration and photography. These were analysed and allocated to the currently existing terminologies regarding the numbers of the branches (Part 1), and these subgroups were evaluated according to the variability of the trunk formations (Part 2). In Part 1, four subgroups could be classified (A, B, C and D). Group A included a total number of three branches (n = 50), Group B included four (n = 41), Group C included five (n = 5) and Group D included only two branches (n = 6). Part 2 showed in total 11 different trunk variations. Group A had four trunk variations: A1 (n = 38), A2 (n = 5), A3 (n = 2) and A4 (n = 6); Group B also had four variations: B1 (n = 16), B2 (n = 18), B3 (n = 3) and B4 (n = 4); Group C displayed two variations: C1 (n = 1) and C2 (n = 4); and in Group D, there was only one variation observed D1 (n = 6). Branching patterns were highly variable and inconsistent in terms of the number of branches and trunk variations, which resulted in different possible and justified interpretations and classifications. A new terminology should be defined cooperatively among anatomists and clinicians that will be useful for everybody. We propose a terminology oriented to the associated muscles.

    Abstract Objective: To evaluate potential clinical parameters having an impact on visual outcome after endoscopic optic nerve decompression in acute optic neuropathy patients.
    Methods: A retrospective chart review of patients with acute optic neuropathy, who underwent endoscopic optic nerve decompression between June 2001 and November 2018 at an academic center was performed. Patients were divided into groups according to visual improvement after surgical treatment (yes/no). Following clinical parameters were compared between groups: perioperative steroid use, evidence of optic nerve affection in preoperative neuroimaging, additional optic nerve sheath incision, surgery delay and preoperative C-reactive protein (CRP) levels. Further subgroups analyses were conducted based on etiology (trauma/tumor).
    Results: Among 32 included cases, 16 patients (50%) reported visual improvement after endoscopic optic nerve decompression. There was no significant difference in visual improvement between etiology subgroups (trauma: n = 9/20 (45%) vs. tumor: n = 7/12 (58.3%), p = 0.465). Tumor subgroup patients with visual improvement had a significantly higher prevalence of optic nerve affection in preoperative neuroimaging than those without visual improvement (p = 0.018, φ = 0.683). Perioperative steroid administration was negatively associated with visual outcome (p = 0.034, φ = 0.375). Nerve sheath incision, surgery delay and preoperative CRP levels did not have a significant impact on visual outcome (p > 0.05).
    Conclusion: Radiological findings can help as an indicator for surgical treatment since an affected optic nerve in preoperative neuroimaging resulted in better visual outcome after surgery. The use of steroids should be considered more carefully since it did not show any beneficial effect.

    Abstract Introduction: Percutaneous radiofrequency facet denervation (PRFD) by thermocoagulation is a useful treatment for nonspecific thoracic pain syndrome. To guarantee that maximal thermal lesion is applied to the nerve, it is essential to have precise knowledge of the topography of the thoracic dorsal branches of the spinal nerves. This special anatomy was investigated, and the results were compared with the existing technique for PRFD, where the active needle tip is placed in the junction of the superior articular process and the transverse process.
    Methods: Twenty thoracic spines of cadavers (10 females and 10 males) embalmed according to Thiel's method were bilaterally dissected. After careful removal of skin and subcutaneous fat tissue, the lateral and medial branches were traced centrally. In addition, the articular branch to the thoracic facet joint was traced peripherally. The distance of the medial branch to the inferior articular process at the level of the nerve passing the superior costotransverse ligament was measured.
    Results: The dorsal branch bifurcates into lateral and medial branches medial to the superior costotransverse ligament. The medial branch runs laterally first to pass in between two parts of the intertransverse ligament running dorsally and to turn medially superficial to this ligament. The zygapophysial branch always originated from the medial branch passing the inferior articular process laterally by running caudally to turn medially and send branches to the capsule of the zygapophyseal joint. The distance of the medial branch lateral to the inferior articular process was constantly 3 mm.
    Conclusions: The current technique of PRFD at the thoracic spine targets the medial branch distal to the separation of the articular branch, rendering the lesion ineffective at denervating the zygapophyseal joint. For selective thermocoagulation of the articular branches of the thoracic zygapophyseal joint, a new technique should be developed. We propose an anatomically informed needle position that can now be confirmed clinically.

    Abstract Introduction: The zygapophyseal joints represent one possible cause for back pain. Therefore, many interventions are targeting the denervation of the facet joints. The aim of this study is to describe the course of the medial branch of the dorsal branch of the spinal nerve and its articular branches to the zygapophyseal joints in the segments T10-T12.
    Methods: The medial branches in the thoracic segments T10-T12 were dissected in 20 Thiel embalmed cadavers. An Eschenbach magnifying glass (4.0× magnification) was used during dissection preserving the articular branches. The topography and the branching pattern of the medial branches was observed.
    Results: The course of the nerves in the segments T10-T12 differed from each other because of the different osseous anatomy of each segment. The medial branch at the segment T10 crossed the tip of the transverse process in 28 of the 40 hemivertebral specimens. In the remaining cases it passed superior to the transverse process. At T11 the medial branch ran constantly through an osteofibrous canal. At the segment T12 the medial branches showed a similar course to the medial branches in the lumbar region. In many cases two articular branches, which arose from the medial branch were identified.
    Conclusions: The results of this study show a considerable anatomic variety at the segment T10. It also demonstrates that the transverse process is an important landmark to encounter the medial branch. Furthermore, the possibility of a double innervation of the facet joints should always be considered.
