Some biological characteristics of transferred free flaps

Abstract

At the Clinic for plastic surgery and burns of the MMA, we examined 33 patients with transferred 5 cutaneous, 18 myocutaneous, and 10 osteocutaneous free flaps out of which 10 were done on foot, 13 on the lower leg, and 10 on the face. We analyzed the blood circulation (patency of arterial microanastomosis and perfusion) of transferred free flaps, recovery of sensitivity, functioning of the sebaceous and sweat glands as well as histomorphologic changes in the skin of the transferred free flaps during the period of 6 up to 36 months after the free flap transfer and compared with the same characteristics of the skin and tissue of the surrounding area of the recipient region.

Analysis of reconstructive methods in surgical treatment of nasal skin defects

“…Twopoint discrimination and functioning of sweat glands was also examined. Pain sensitivity was evaluated using pinprick, light touch was measured using von Frey hairs and hot and cold sensitivity was tested by thermal esthesiometer with water +10°C or water +40 °C 10,11 . The lowest value at which the patient correctly identified 2 points at least 3 out of 5 ti-mes was recorded as the value for 2-point discrimination.…”

“…The lowest value at which the patient correctly identified 2 points at least 3 out of 5 ti-mes was recorded as the value for 2-point discrimination. The functioning of sweat glands was tested using ninhydrin test 11 . Sensory function and functioning of sweat glands was assessed on the central portion and 4 peripheral sectors of each flap and full thickness skin graft.…”

Sensibility of vagina reconstructed by McIndoe method in Mayer-Küster-Rokitansky-Hauser syndrome

“…Ispitivanje senzibiliteta obuhvatilo je ispitivanje osećaja dodira, toplote i hladnoće na tri različita mesta (ulaz, sredina zida i dno), kod ispitanica sa rekonstruisanom i ispitanica sa normalnom vaginom. U literaturi nema podataka o ispitivanju senzibiliteta, izvršenom na ovaj način za rekonstruisanu sluzokožu vagine, ali postoje podaci o ispitivanju senzibiliteta transplantata kože i režnjeva u drugim oblastima rekonstruktivne hirurgije 20,21,24,25 .…”

Impact of groin flap ischemia-reperfusion on red blood cell micro-rheological parameters in a follow-up study on rats

“…It is known from the clinical practice, that one of the most crucial factors for transferred free-flap survival is the ischemia-reperfusion [1,8,12,16,28,30]. The possible causes for flap ischemia and necrosis include intraoperative and postoperative ones.…”
