BACKGROUND: Modern trends in reconstructive surgery involve the use of free perforator flaps to reduce the donor site morbidity. The course of perforator vessels has a great anatomic variability and demands detailed knowledge of the anatomical relationships and the variability of the course of the perforators. The numerous modifications to perforator nomenclature proposed by various authors resulted in confusion rather than simplification. In our study, we focused on the hypothesis that a septocutaneous perforator traverses from the given source vessel to the deep fascia adherent to but not to within the septum itself. METHODS: Sixty-nine septocutaneous perforators from three different limb donor sites (lateral arm flap, anterolateral thigh flap, and radial forearm free flap) were collected from the gross pathology specimens of 14 fresh cadavers. The gross picture and the cross-sections with the histological cross-sections on different levels were examined to determine the position of the vessel to the septal tissue. RESULTS: Of the observed 69 septal perforators, 61 (88.5%) perforators were adherent to but not within the septum. The remaining eight (12.5%) perforators passed through the septum. All these eight perforators were found in multiple different cross-section levels (2 of 19 in lateral arm flap, 3 of 27 in anterolateral thigh flap, and 3 of 23 in radial forearm free flap). CONCLUSION: Although septocutaneous vessels appear identical macroscopically, microscopically two types of vessels with paraseptal and intraseptal pathways are observed. The majority of these vessels are merely adherent to the septum having a paraseptal pathway, while a minority are within the septum and are "true" septocutaneous perforators. It is advisable to dissect with a piece of the septum in order to avoid damage or injury to the perforator.

INTRODUCTION: Our face plays an important role in communication and social life. Defects of the face have a big impact on socializing and psychics of patients with its deformities. A good esthetic outcome is an important task of each reconstructive surgery. With a modern concept of nose reconstruction, it is possible to achieve a better esthetic and functional outcome than it was possible with one phase reconstructions before. There was a specific tool missing to measure patients reported outcome and objectively evaluate benefits of nose reconstruction from a patients point of view and get reliable feedback about the whole procedure. The goal of this paper is to develop such a questionnaire. MATERIALS AND METHODS: A pilot questionnaire was developed with literature input. The questionnaire was tested on five patients. Based on patients feedback and a review from a psychologist, the second version of the questionnaire was made. It was sent to 39 patients, who underwent nose reconstruction in the years 2016-2020. After two appeals, 34 completed questionnaires were sent back (87,2%). The final version of the questionnaire was developed after a thorough mathematic and statistical analysis of collected data. RESULTS: The group of patients who completed the questionnaire consisted of 16 females (47%) and 18 males (53%). On average, the patients were 69 years old (17-88 years). The final questionnaire is structured into six categories from A to F: A - general information defining the patient and purpose for reconstruction, B - satisfaction with esthetic outcome, C - satisfaction with function and stability, D - satisfaction with medical treatment, E - social and psychological impact, F - overall satisfaction. Most of the questions use a 5-point rating scale. CONCLUSION: The questionnaire enables the patients to provide feedback on particular aspects of the treatment and their overall satisfaction with the whole procedure and its outcome. With statistical analysis, it is possible to discover specific treatment aspects that have crucial impact on overall satisfaction with the whole procedure. A patient-reported outcome helps to improve the quality of provided health care and the quality of patient life.

UNLABELLED: Background/Aims/Objectives: To verify the transfer of evoked potentials through anastomosis of an experimentally created micturition reflex arc and to detect said potentials directly on the detrusor and sphincter of rabbit urinary bladder. METHODS: During 2013-2015, 17 rabbits were operated upon and measurement followed during reoperation 3-16 months later. Suitable ventral spinal roots were electrophysiologically detected following laminectomy, and a somatic-central nervous system-autonomic micturition reflex arc was created. During reoperation, the ventral root was stimulated above and below the anastomosis, the evoked potentials on the bladder detrusor and sphincter were measured, and intravesical pressure was monitored. RESULTS: With stimulation above the anastomosis, 9 animals (53%) displayed a urinary bladder detrusor response and 7 (41%) a sphincter response. Four rabbits (24%) had elevated intravesical pressure. During the control stimulation below the anastomosis, we detected a detrusor response in 7 animals (41%), a sphincter response in 5 (29%), and elevated pressure in 4 (24%). Neither induction of micturition nor decrease in external sphincter activity occurred. CONCLUSIONS: Creation of a somatic-CNS-autonomic reflex arc is technically possible. However reflex activity transferring through the anastomosis is detectable on the detrusor only in some individuals, and is unable to induce a micturition reflex with or without accompanying detrusor-sphincter dyssynergia.
