[Therapeutic strategies for covering traumatic defects of the heel area]. / Therapiestrategien zur Deckung traumatischer Defekte der Fersenregion.

Tissue defects of the heel region are a challenging problem. Various reconstructive techniques were performed in 44 patients with 59 defects around the heel region, who were treated between 1994 and 1999 following a traffic accident in 27%, a burn injury in 25%, and other traumatic causes in 48%. Free flap coverage was performed in 20 defects (36%), local flaps were used in 15 patients (27%) and autologous skin transplantation in 21 patients (36%). The overall complication rate was 18% with the highest rate after local flap procedures. A therapeutic strategy was developed, which is based mostly on the localization and extension of the defect area.

[First continuous nerve monitoring in thyroid gland surgery]. / Erstes kontinuierliches Nerven-Monitoring in der Schilddrüsenchirurgie.

UNLABELLED: A new "all in one" sensing device was developed for continuous transtracheal intraoperative monitoring and in situ detection of the recurrent laryngeal nerve (RLN) during thyroid surgery. PATIENTS AND METHODS: The new system is based on a double-balloon endotracheal tube with integrated atraumatic stimulating and tracing electrodes. The recurrent laryngeal nerve is stimulated transtracheally and compound action potentials are recorded from the laryngeal muscles. Fifty-five patients were introduced into a phase-one clinical trial. Thirty-five patients with primary thyroid operations, 20 patients with reoperations, 10 of whom had neck dissections. All patients were evaluated laryngoscopically and phoniatrically by an ENT specialist before and after surgery. RESULTS: Compound muscle action potentials were recorded continuously during the whole operation and responded sensitively to tension and pressure to the nerve. There were no accidental permanent RLN palsies. CONCLUSION: The new system offers five advantages: (1) it is atraumatic; (2) it is easy to use; (3) it can monitor continuously with an audio feedback to the surgeon; (4) it works outside the operation field; and (5) it is highly sensitive, even indicating reversible irritation to the nerve.
