[Retrospective Evaluation of the Use of a Dermal Substitute in Septorhinoplasty].

Background: At the present time, various methods exist for camouflaging the dorsum of the nose in septorhinoplasty. The subject of this paper is a retrospective descriptive evaluation of the surgical use of the bovine collagen/glycosaminoglycan matrix Integra Dermal Regeneration Template Single Layer Thin (IDRT-SL Thin) developed by Integra LifeSciences in septorhinoplasty procedures.

Methodology: The focus of this work is to evaluate the postoperative tolerability, the safety, and the course of wound healing when IDRT-SL Thin is applied as a collagen sheet in septorhinoplasty.

[Statement on hospitalization of children after otorhinolaryngologic interventions in Germany : Position paper from the Pediatric Otorhinolaryngology Working Group of the German Society of Otorhinolaryngology, Head and Neck Surgery].

The inpatient care of children after ENT surgery is organized heterogeneously across Germany. In this statement, the working group on Pediatric ENT comments a national survey on the status quo of child care after ENT interventions in German hospitals. The statement should serve as a basis for further interdisciplinary discussion.

[Teaching otorhinolaryngology in times of COVID-19: to what extent can digital formats replace face-to-face teaching?].

Objective: Due to the coronavirus disease 19 (COVID-19) pandemic, postgraduate training in otorhinolaryngology in 2020 was transferred completely from face-to-face to digital teaching. This paper assesses whether this change was possible without a reduction in the quality of teaching and learning.

Methods: Results of final written examinations were compared for the years 2016-2020, and the results of the teaching evaluation by the students for 2017-2020.

HoloSelecta dataset: 10'035 GTIN-labelled product instances in vending machines for object detection of packaged products in retail environments.

To assess the potential of current neural network architectures to reliably identify packaged products within a retail environment, we created an open-source dataset of 295 shelf images of vending machines with 10'035 labelled instances of 109 products. The dataset contains photos of vending machines by the provider Selecta, the largest European operator of vending machines. The vending machines are a mix of machines in public and private office spaces.

[Surgical management of high-grade ear malformations in childhood].

Malformations of the ear are the most common dysplasias in childhood. Ear malformations are classified into dysplasias of the auricle, of the ear canal, and of the middle and inner ear. The latter types are fortunately relatively rare.

[Complex fracture of the larynx caused by a horse kick].

Every blunt laryngeal trauma requires examination by an ENT physician and may necessitate observation for a number of hours. The literature shows a heterogeneous picture regarding airway management (tracheotomy vs. intubation).

[ENT emergency treatment and alcohol related head and neck injuries].

The spectrum of ENT-diseases can differ widely among emergency departments (ED) of different geographic regions. Especially in terms of head and neck trauma a higher number of injuries can be expected in large cities due to alcohol related violence.The ED of a large hospital situated in the center of Hamburg Germany was analysed for ENT-emergency treatments in 2011 retrospectively.

[Multiple hemangiomas, polyposis coli, endometrial and papillary thyroid cancer].

A 27-year-old female patient presented with multiple lipomas and cavernous hemangiomas of the skin, hemangioma of the parotid gland, polyps of the gastrointestinal tract and endometrial carcinoma. After 1 year the patient presented with papillary thyroid carcinoma and a diagnosis of Cowden syndrome (CS) was made. Genetic testing revealed a pathogenic PTEN gene mutation.

[Intraorbital wooden foreign body undetected on CT].

We present the case of an orbital fracture and a wooden foreign body found during surgery. The patient had undergone a pre-operative computed tomography scan but the foreign body had not been seen on these images. We discuss the difficulties in demonstrating wooden objects on CT and describe indicators in patient history, examination findings and radiological signs that might suggest the presence of a wooden object.

[MALT and the Epithelium of the Middle Ear Mucosa. Morphological Studies].

Introduction: The mucosa of the middle ear and the Eustachian Tube changes in different ways when faced with recurrent episodes of inflammation. It thereby adapts to these new stimuli and insults from the environment. One of these changes is the development of MALT (mucosa associated lymphoid tissue).

[Bright white vocal folds and capillary ectasias. Late sequelae after radiotherapy].

We report on visible laryngeal changes after radiotherapy. In this study, three women and two men aged 50-64 years were involved. In three cases, the primary tumor was a carcinoma of the thyroid gland and in one case a carcinoma of the esophagus.

[Experiences with intraoperative application of prednisolone during Isshiki type I thyroplasty].

Laryngeal edema is considered a postoperative problem in phonosurgery. In a prospective study we examined if a single intraoperative application of prednisolone can decrease the incidence of postoperative laryngeal edema after Isshiki type I thyroplasty. We examined ten patients undergoing unilateral type I thyroplasty [seven men and three women, age range: 19-60 years (average: 48 years)].

[Is the observation of patients with sleep-apnea-syndrome after surgery of the upper airway in an intensive care unit generally necessary?].

Background: Although it is known that after surgery of the nose and/or the paranasal sinuses serious complications can arise for patients suffering from Sleep-Apnea-Syndrome (SAS), there exists no general recommendation for postoperative care of these patients. This retrospective analysis is dealing with the question whether it is generally necessary to observe SAS-patients after nasal surgery including intubation in an Intensive Care Unit (ICU).

Patients And Methods: 24 Patients of the ORL-Dept.

[Orbital stabilisation with suprabrow myofascial transposition flaps].

Background: Common reasons for orbital defects are midfacial traumas or defects following tumor resection within the sinu-orbital region. In these cases, reconstruction of the medial or inferior orbital wall often is required. Common materials for orbital reconstruction, such as titanium-mesh, are used where epithelialisation problems are frequently encountered.

[The monthly interesting case - case no. 63].

Angiosarcomas are rare, aggressive tumors of vascular origin. They occur most often in areas of long term sun exposed skin in the elderly, in long standing lymphoedema or after radiation therapy. The prognosis is poor, radical surgery required, in addition radiation or chemo-therapy are considered to be therapeutical options.

[Transposition flaps for reconstruction of deep defects of the medial eyelids. Fasciocutaneous rotations- and transposition flaps and modified pure fascial transposition flap].

Tumor resection in the medial canthal area may result in deep defects with involvement of the ethmoidal bone and destruction of the lacrimal ducts. While shallow defects with little involvement of bone can be covered with the classic glabellar flap, deep defects require larger fasciocutaneous flaps from the forehead that can also be used for the reconstruction of the involved medial parts of the eyelids. The preferred techniques of the median or paramedian transposition flaps and a modified paramedian fascial flap for reconstruction of the medial orbital wall and support of the orbit are described.

[Reconstruction of the frontal sinus with a calvarium split galea periosteum transplant after inflammatory complications].

After reconstruction of the frontal sinus with alloplastic material, with or without obliteration of the lumen, inflammatory complications may occur. The authors present a plastic-surgical functional reconstruction technique for revision surgery in cases of inflammatory complications following frontal sinus implantation of alloplastic material, by means of a modified autologous calvarian split graft. The inflammatory complications after primary reconstruction or obliteration of the frontal sinus occurred after a period of 1-10 years.

[Therapy of iatrogenic pharyngocutaneous fistulas--possibilities of surgical treatment].

Background: During tumor surgery of the upper respiratory and digestive tract, pharyngocutaneuos fistulas may occur postoperatively. Predisposing factors are tissue disorders, as can be seen after radiation therapy or wound infections. The aim of this study was to create a systematic approach to the treatment of such complications.
