Muscular Versus Non-Muscular Free Flaps for Soft Tissue Coverage of Chronic Tibial Osteomyelitis.

World J Plast Surg 2018 Sep;7(3):294-300

Department of Plastic, Reconstructive and Aesthetic Surgery, Geneva University Hospitals, Faculty of Medicine, University of Geneva, Switzerland.

Background: Eradication of chronic tibial osteomyelitis necessitates aggressive debridement is often followed by soft tissue reconstruction. Muscular flaps are said to be more effective than non-muscular flaps for infection treatment, while fasciocutaneous and perforator flaps are considered to be less invasive and offering a better aesthetic result.

Methods: In this study, we reviewed 24 consecutive cases of chronic tibial osteomyelitis treated according to a specific protocol in a tertiary hospital. Soft tissue coverage was done with either muscular or non-muscular free flaps. Infection recurrence and complications were compared between different flap types. Additionally, we assessed the long-term functional and aesthetic results and patient's satisfaction.

Results: Muscular flap was used in 13 patients (13 latissimus dorsi and 1 serratus anterior) and 11 patients underwent fasciocutaneous/perforator flaps [1 anterolateral thigh flap, 4 lateral arm flaps, 5 thoracodorsal artery perforator (TAP) flaps and 1 radial forearm flap]. Infection was resolved for 84.6% of patients in the muscular flaps group and 90.9% in the non-muscular flaps group. None of the patients with muscular flaps were satisfied with the aesthetic appearance of their reconstructed leg when compared to 83.3% of patients with non-muscular flaps. Also, a slight regain of touch sensitivity was acknowledged in the non-muscular flap group compared to the muscular.

Conclusion: In this study of adult chronic tibial osteomyelitis cases, we demonstrated that fasciocutaneous and perforator free flaps offer a comparable efficacy to the muscle flaps for infection treatment, with a significantly higher patient satisfaction and aesthetic result.

Is Salvage of Recently Infected Breast Implant After Breast Augmentation or Reconstruction Possible? An Experimental Study.

Aesthetic Plast Surg 2018 Apr 23;42(2):362-368. Epub 2018 Jan 23.

INSERM, Univ. Lille, CHU Lille, U1189-ONCO-THAI-Image Assisted Laser Therapy for Oncology, Lille, France.

Introduction: The reinsertion of an infected implant when peri-prosthetic infection occurs early after breast augmentation or breast reconstruction remains controversial. In this experimental study, the authors tried to remove bacteria, and their biofilm, from the colonized surface of breast prostheses, without damaging their integrity.

Materials And Methods: A total of 112 shell samples of silicone breast prostheses, smooth (SPSS) and textured (TPSS), were colonized by S. epidermidis (SE) or S. aureus (SA) strains, all able to produce biofilms. After 15 days, all the samples were removed from the contaminated culture broth and constituted 4 groups of 20 contaminated samples: SPSS/SE (group I), SPSS/SA (group II), TPSS/SE (group III), TPSS/SE (group IV). In another group-group SEM-, 16 colonized samples were used for documentation with scanning electron microscopy (SEM). The remaining 16 samples were used to test the limits of detection of the sterility test. All samples of groups I-IV and 8 samples of group SEM were « washed » with a smooth brush in a povidone-iodine bath and rinsed with saline solution. A subset of the washed samples was sent for SEM and the others were immersed in sterile broth and were incubated at 35 °C for 3 weeks (groups I-IV).

Results: Fifteen days after contamination, all the samples in groups I-IV were colonized. In the SEM group, SEM images attested to the presence of bacteria in biofilm attached to the shells. After cleaning, SEM did not reveal any bacteria and there was no visible alteration in the outer structure of the shell. Sterility tests performed after decontamination in groups I-IV remained negative for all the samples.

Conclusion: Breast prostheses recently contaminated with Staphylococci, frequently involved in peri-prosthetic breast implant infection and capable of producing biofilms, can be efficiently decontaminated by the procedure used in this study. Our decontamination procedure did not alter the surface structure of the prostheses. This decontamination procedure could allow reinsertion of an infected implant when peri-prosthetic infection occurs early after breast augmentation or breast reconstruction and when a salvage procedure is indicated.

[Sensibility of the abdomen after high superior tension abdominoplasty].

Ann Chir Plast Esthet 2009 Dec 13;54(6):545-50. Epub 2009 Feb 13.

Service de chirurgie plastique, centre hospitalier de Luxembourg, 4, rue Barblé, 1210 Luxembourg, Luxembourg; Service de chirurgie plastique, CHU Sart-Tilman, 4000 Liège, Belgique.

Introduction: Patients who undergo an abdominoplasty frequently complain about the loss of sensibility of the abdominal wall. In this study, we analyze this sensibility after the high tension abdominoplasty.

Patients And Methods: This is a prospective study of 23 females operated between July 2003 and January 2005. The abdominoplasty technique used in our study combines extensive liposuccion, limited undermining centered on the linea alba and traction sutures. The sensibilty tests are carried out preoperatively, as well as at 3 and 6 months postoperatively. The three components of the skin sensibility -tactile, algesic and thermic- are evaluated in four differents areas of the abdomen.

Results: In the lateral areas of the abdomen (liposucted only), the thermoalgesic sensibility is diminished at 3 months and completely recovers at 6 months. At 3 months postoperatively, the tactile sensibility is even better than the preoperative one and continues to improve by 6 months. The postoperative hypogastric area is widely undermined during surgery. In this area, the three types of sensibility are heavily altered at 3 months and only partially recover at 6 months. The undermining of the postoperative epigastric area is limited. In this zone, the postoperative thermoalgesic sensibility is diminished at 3 months, but completely recovers at 6 months. At 3 months, the tactile sensibility is less than the preoperative one, but it improves with time to even exceed the preoperative values at 6 months.

Conclusion: The high tension abdominoplasty only needs a limited undermining and largely preserves the innervation of the abdominal flap. Only the hypogastric area, largely undermined, presents a sensitivity loss. These results are better than those previously reported in the literature.

[A case of iatrogenic scrotal elephantiasis: reconstruction of the scrotal purse and the cutaneous sleeve of the penis with local skin flaps].

Ann Chir Plast Esthet 2008 Feb 26;53(1):79-83. Epub 2007 Mar 26.

Università degli Studi di Sassari, Cattedra di Chirurgia Plastica, V.le San Pietro 43/b, 07100 Sassari, Italie.

Scrotal elephantiasis is a pathology of often unknown etiology. Symptomatology is characterized by an oedematius infiltration of skin and subcutaneous tissue, hard-bound aspect and purplished color. The scrotum, the penis and the perineal area are gradually affected. This pathology is very invalidating for the patient, on functional, sexual and aesthetic aspects. The authors present the case of a 58-year-old man with an enormous scrotal mass invading the penis and drowning the testicular elements, which were impossible to palpate. The aetiology was determined by exclusion and an iatrogenic origin following the cure of bilateral inguinal hernia was retained. Resection of the scrotal mass was performed. The reconstruction of the scrotal purse and the cutaneous sleeve of the penis were carried out using local flaps of the remaining healthy skin.
