Pre-operative high-frequency ultrasound: a reliable management tool in auricular and nasal non-melanoma skin cancer.

Background And Objectives: The knowledge of depth infiltration in non-melanoma skin cancer (NMSC) using pre-operative ultrasound could enable clinicians to choose the most adequate therapeutic approach, avoiding unnecessary surgeries and expensive imaging methods, delaying diagnosis and treatment. Our single-center retrospective study determined the usefulness of high-frequency ultrasound (HFUS) for depth infiltration assessment in auricular and nasal NMSC and assessed the subsequent change in therapeutic approach.

Patients And Methods: In 60 NMSC cases, we assessed the accuracy of HFUS in cartilaginous/bone infiltration detection as well as the correlation of sonographic and histological parameters.

Ultrasonographic Assessment of Depth Infiltration in Melanoma and Non-melanoma Skin Cancer.

The preoperative assessment of infiltration depth in melanoma and non-melanoma skin cancer by means of high-frequency ultrasound (≥18 MhZ) is essential for optimizing the therapeutic approach in our patients. Often, histologically confirmed skin tumors are directly referred to surgical departments for resection, and sonography is increasingly helping us identify those subjects who are no longer candidates for extensive surgical interventions. In cases of deep tumor infiltration, with potential surgical failure e.

Retrospective Analysis of Complication Rates Associated With Auricular Reconstruction After Skin Cancer Surgery.

Background: There is limited data regarding postoperative complications after microtia surgery or tympanoplasty; however, complication rates after pinna reconstruction following tumor resection and comorbidities associated with suboptimal outcomes have not been investigated so far.

Objective: To examine the incidence of postoperative complications after auricular reconstruction surgery following tumor resection and determine the association between postoperative complications and defect size, patients' comorbidities, and reconstruction type.

Methods And Materials: In a retrospective case series ( = 146, January 2014 to October 2018), we examined the surgical outcome and amount of postoperative complications following auricular surgery as well as the association with different comorbidities.

Surgical management of skin cancer and trauma involving the middle third of the auricle.

The main causes of acquired auricular defects are surgical treatment of skin tumors and trauma. Due to the complex anatomy of the external ear, surgical reconstruction of defects in this area is challenging for surgeons, especially in case of midhelix-antihelix involvement with significant loss of soft tissue and cartilage. Our purpose is to illustrate the main reconstructive techniques of large midhelix and antihelix defects, as well as the advantages or disadvantages associated with each surgical procedure.

Chirurgische Versorgung von Hautkrebs und Trauma im mittleren Drittel der Ohrmuschel.

Die Hauptursachen erworbener Ohrmuscheldefekte sind chirurgische Behandlung von Hauttumoren und Traumata. Wegen der komplexen Anatomie des Außenohrs ist die chirurgische Rekonstruktion von Defekten in dieser Region für Operateure herausfordernd, insbesondere wenn die mittlere Helix und Anthelix von größeren Weichteil- und Knorpelverlusten betroffen sind. Wir stellen hier die wichtigsten Techniken zur Rekonstruktion großer Defekte der mittleren Helix und Anthelix sowie die Vor- und Nachteile jedes chirurgischen Verfahrens vor.

Dermatochirurgie bei Kindern: Gegenwärtiger Stand zu Indikation, Anästhesie, Analgesie und potentiellen perioperativen Komplikationen.

Hintergrund: Anders als Erwachsene benötigen Kinder bei dermatochirurgischen Eingriffen besondere Aufmerksamkeit; die Anwendung verschiedener Analgetika, Anästhetika oder Sedativa erfordert eine gründliche Kenntnis von Pharmakokinetik und -dynamik der Medikamente. Außerdem können Medikamente zur Sedierung/Allgemeinanästhesie bei operierten Kindern zu Anästhesie- oder Analgesie-bedingten Komplikationen einschließlich Störungen der geistigen Entwicklung führen. ZIEL: Auf Basis unserer klinischen Erfahrung und einer Literaturübersicht stellen wir die gängigsten in der pädiatrischen Dermatochirurgie verwendeten Analgetika, Anästhetika und Sedativa dar und diskutieren Risiken und Komplikationen nach dermatochirurgischen Eingriffen.

Dermatologic surgery in children: an update on indication, anesthesia, analgesia and potential perioperative complications.

Background: Children undergoing dermatosurgical procedures require, unlike adults, particular attention; the administration of various analgesics, anesthetics or sedatives requires a thorough knowledge of drug pharmacokinetics and pharmacodynamics. Furthermore, there are concerns that drugs used for sedation/general anesthesia may result in anesthetic/analgesic complications in children undergoing surgery, with a risk of impaired mental development.

Objectives: Based on our clinical experience and a literature review, we illustrate the most commonly used analgesic, anesthetic and sedative drugs in pediatric dermatosurgery, and identify risk factors and complications following dermatosurgical procedures.
