[Management of side effects following hyaluronic acid filler injections].

With the increase of esthetic procedures using hyaluronic acid injections, the risk of complications also increases. Due to their complexity, interdisciplinary treatment is often necessary. In recent months, three cases have been treated on an interdisciplinary basis at Leipzig University Medical Center.

Design and evaluation of an AR-based thermal imaging system for planning reconstructive surgeries.

Introduction: Thermal imaging can be used for the non-invasive detection of blood vessels of the skin. However, mapping the results to the patient currently lacks user-friendliness. Augmented reality may provide a useful tool to superimpose thermal information on the patient.

Effect of the lateral wall valgisation in the treatment of patients with endocrine orbitopathy.

Orbital decompression is an established procedure used to correct exophthalmos that results from excess orbital soft tissue. This study aimed to explore a new minimally-invasive technique that features three-dimensional planning and patient-specific implants for lateral valgisation (LAVA) of the orbital wall. We analysed the outcomes of this procedure in nine endocrine orbitopathy (EO) patients (32-65 years of age with a mean clinical activity score of 4.

Reference Values of Cerebral Artery Diameters of the Anterior Circulation by Digital Subtraction Angiography: A Retrospective Study.

A threshold-based classification of cerebral vasospasm needs reference values for intracranial vessel diameters on digital subtraction angiography (DSA). We aimed to generate adjusted reference values for this purpose by retrospectively analyzing angiograms and potential influencing factors on vessel diameters. Angiograms of the anterior circulation were evaluated in 278 patients aged 18−81 years.

The Supratrochlear Artery Sign-A New Piece in the Puzzle of Cerebral Vasospasm.

Background: Cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH) has been extensively investigated, but the impact of collateralization remains unclear. We investigated the predictive value of collateral activation for delayed cerebral ischemia (DCI)-related infarctions and functional outcome.

Methods: Data from 43 patients with CVS (January 2014 to August 2021) were evaluated for the angiographic presence of leptomeningeal and ophthalmic collaterals (anterior falcine artery (AFA), supratrochlear artery (STA), dorsal nasal artery (DNA)) on internal carotid artery angiograms.

Nimodipine vs. Milrinone - Equal or Complementary Use? A Retrospective Analysis.

Background: Cerebral vasospasm (CVS) continues to account for high morbidity and mortality in patients surviving the initial aneurysmal subarachnoid hemorrhage (SAH). Nimodipine is the only drug known to reduce delayed cerebral ischemia (DCI), but it is believed not to affect large vessel CVS. Milrinone has emerged as a promising option.

No Significant Bone Resorption after Open Treatment of Mandibular Condylar Head Fractures in the Medium-Term.

Open treatment of condylar head fractures (CHF) is considered controversial. In this retrospective cohort study our primary objective was therefore to assess bone resorption and remodeling as well as patients function after open treatment of CHF in a medium-term follow-up (15.1 ± 2.

Standardized Classification of Cerebral Vasospasm after Subarachnoid Hemorrhage by Digital Subtraction Angiography.

Background: During the last decade, cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH) was a current research focus without a standardized classification in digital subtraction angiography (DSA). This study was performed to investigate a device-independent visual cerebral vasospasm classification for endovascular treatment.

Methods: The analyses are DSA based rather than multimodal.

Standardized Diagnostic Workup and Patient-Centered Decision Making for Surgery and Neck Dissection Followed by Risk-Factor Adapted Adjuvant Therapy Improve Loco-Regional Control in Local Advanced Oral Squamous Cell Carcinoma.

Background: Standardized staging procedures and presentation of oral squamous cell carcinoma (OSCC) patients in multidisciplinary tumor boards (MDTB) before treatment and utilization of elective neck dissection (ND) are expected to improve the outcome, especially in local advanced LAOSCC (UICC stages III-IVB). As standardized diagnostics but also increased heterogeneity in treatment applied so far have not been demonstrated to improve outcome in LAOSCC, a retrospective study was initiated.

Methods: As MDTB was introduced into clinical routine in 2007, 316 LAOSCC patients treated during 1991-2017 in our hospital were stratified into cohort 1 treated before (=104) and cohort 2 since 2007 (=212).

Eyes wide shut: necessity and effect of adjunctive procedures after decompression surgery in patients with endocrine orbitopathy.

Background: Orbital decompression surgery is frequently the last therapeutic measure in the surgical treatment of endocrine orbitopathy (EO). Additional rehabilitative and corrective surgical treatments are often used to improve the resulting eyelid stigmata, such as an increased lid aperture and scleral show. The aim of the study was to evaluate the effect of adjunctive surgical procedures after orbital decompression surgery in patients with EO.

Mixed reality in oral and maxillofacial surgery: a symbiosis of virtual and augmented reality or a pointless technological gadget?

Introduction: Mixed reality (MR) represents a new evolution in technological development that combines both virtual reality (VR) and augmented reality (AR) to create a blend of the physical and digital worlds. However, the potential role of MR in preoperative diagnostics in oral and maxillofacial surgery has not been scientifically investigated and remains generally unclear. This article presents a workflow that integrated MR in its scheme.

Improved access in minimally invasive temporomandibular joint surgery through a novel endaural template.

Background: Digitally designed surgical templates for minimally invasive temporomandibular joint (TMJ) surgery (MITMJS) are a promising tool for improving the safety of these procedures. Given the TMJ anatomy, the template fitting and intraoperative overview are the most important issues for a safe surgery. This article is a technical advance article that aims to describe an endaural surgical template based on the Moses approach as a possible solution in TMJ surgery.

Quality of life in patients with oral hard or soft tissue defects after reconstructive microsurgery.

With current advances in medicine, many surgical methods have emerged for the reconstruction of soft and hard tissue defects of the head and neck. Current literature provides only a limited amount of evidence in studies addressing differences in quality of life for specific therapeutic measures in microvascular reconstruction. The validated University of Washington quality of life questionnaire version 4 (UW-QoL v4), a distress thermometer, and two questions addressing donor-site morbidity were sent to 134 patients at a tertiary care centre.

Impact of COVID-19 on Oral and Maxillofacial Surgery: Preliminary Results After the Curfew.

Introduction: The COVID-19 pandemic affects basic health care in maxillofacial surgery (MFS) due to the shift in resources and the change in patient disorders treated during the pandemic. This paper aims to elucidate the medical and financial consequences driven by the measures for COVID-19 treatment in a tertiary care centre.

Material And Methods: To evaluate the impact of pandemic measures on daily routines of MFS, the surgical schedule during the first 2 weeks after the onset of the curfew (March 2020), and to compare it with the schedule of the same period of time 1 year earlier.

The ideal auricular protrusion - An interactive perceptual pilot study.

Purpose: Excessive ear protrusion (prominauris) can negatively affect facial appearance. Because the concept of an ideal auriculocephalic angle is controversial, however, it is difficult to define when an obtrusive auricle requires surgical intervention. It is often assumed that angles exceeding 30° require corrective surgery.

Flow Chart for Reconstructive Head and Neck Surgery in Composite Soft and Hard Tissue Defects.

Introduction: Virtual planning of reconstructive surgical procedures in patients with osseous and composite defects in the head and neck region is becoming increasingly a state of the art modality. However, computational algorithms lack the capability of planning the involved soft tissue and vascular pedicle position. The authors present a flow-chart to solve this problem in the reconstruction of defects of the upper and lower jaw.

Donor-site morbidity after harvesting of radial forearm free flaps-comparison of vacuum-assisted closure with conventional wound care: A randomized controlled trial.

Introduction: Radial forearm free flaps (RFFF) are often used to replace tissue removed in head and neck surgery. In recent years, many attempts have been made to reduce donor-site morbidity and to prevent common complications such as infection, skin-graft necrosis, tendon exposure and subsequent impairment of hand function. One promising option is the use of vacuum-assisted-closure wound therapy (VAC).

Automatic detection of perforator vessels using infrared thermography in reconstructive surgery.

Purpose: Knowing the location of the blood vessels supplying the skin and subcutaneous tissue is a requirement during the planning of tissue transfer in reconstructive surgery. Commonly used imaging techniques such as computed tomography angiography and indocyanine green angiography expose the patient to radiation or a contrast agent, respectively. Infrared thermal imaging was evaluated with success as a non-invasive alternative.

Upper-eyelid weight implants for patients with lagophthalmos-comparison of rigid and flexible implants.

Introduction: For treatment of lagophthalmos, metallic weight implants can be inserted in the upper eyelid to aid eyelid closure. Rigid and flexible implants are available. The objective of this study was to investigate the effect of implant type and patient variables on the survival of lid load implants.

Is radical surgery of an inverted papilloma of the maxillary sinus obsolete? a case report.

Background: Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma.

Rare anatomical variation of the brachiocephalic trunk encountered in tracheostomy.

Tracheostomy is a common procedure in head and neck surgery and emergency medicine to secure a patent airway. Surgeons should always be aware of anatomical variants of the branches of the aortic arch, which could lead to life-threatening complications. Open tracheostomy is the safest emergency procedure.

Monitoring of microvascular free flaps following oropharyngeal reconstruction using infrared thermography: first clinical experiences.

The aim of this study is to investigate static and dynamic infrared (IR) thermography for intra- and postoperative free-flap monitoring following oropharyngeal reconstruction. Sixteen patients with oropharyngeal reconstruction by free radial forearm flap were included in this prospective, clinical study (05/2013-08/2014). Prior ("intraop_pre") and following ("intraop_post") completion of the microvascular anastomoses, IR thermography was performed for intraoperative flap monitoring.
