Candida sternal wound infections (SWIs) following cardiac surgery are rare but are associated with a high mortality rate. Guidelines on this topic either propose no suggestions for management or offer recommendations based on a small number of reports. This paper presents a case of a Candida SWI and its successful treatment with debridement using a burr, negative pressure vacuum therapy (NPVT) and dermal grafting. To investigate different methods of treating Candida SWIs following cardiac surgery, a review was completed using the MEDLINE database. Reports without English abstracts and without defined outcomes of therapy for individual patients were excluded. Seventy-seven cases of Candida SWIs following cardiac surgery were identified in 20 articles published since 1999, including our case. Treatment strategies are identified: omentum flap; muscle flap; debridement and secondary wound healing with or without NPVT; debridement and primary closure; incision and drainage; only medical therapy. Patients documented in the articles were classified based on the following outcomes: cured (n = 41 patients [including the present case]), relapse infection (n = 25 patients) and death (n = 11 patients). The various methods used to treat patients were analysed. Delayed closure reoperation with surgical debridement and NPVT have favourable outcomes. In the presence of widespread osteomyelitis, the use of omental flaps is advocated. Treatment with muscle flaps has a high rate of relapse. Debridement and secondary healing or conservative management with antifungals alone can be considered in the treatment of relapsing infection.

Background/aim: The purpose of this study was to investigate the use of tissues with multiple traumas, scarred pedicles, and medial scarring as a flap. Materials and methods: Forty-eight rats were randomly divided into four equal groups. The modified McFarlane flap was chosen as the flap model. In Group 1 (control), a dorsal skin flap was elevated and then sutured back into original position. In the other groups, a two-phase procedure was used. In Group 2 (pedicle incision), scar tissue was created with a skin incision at the prospective pedicle site of the flap and then sutured to its original site. In Group 3 (preconditioning), multiple full-thickness traumas were performed along the entire flap body, and in Group 4 (middle incision) scar tissue was created with a skin incision at the prospective middle region of the flap. Then, after 45 days, dorsal flaps were raised in all rats and then sutured back into position. Seven days later, flap survival was evaluated through microangiography and histological evaluation of flap segments. Histopathological examination included assessment of the number of vessels, necrosis, infiltration with polymorphonuclear leukocytes, edema, fibrosis, inflammation, increase in fibroblast activity, and neovascularization. Results: The flap survival rates were 66.78% in Group 1, 68.05% in Group 2, 68.5% in Group 3, and 60.01% in Group 4. The flap survival rate was significantly lower in Group 4 (p < 0.05). There was no significant difference in flap survival between Groups 1, 2, and 3. On microangiographic examination, the vascular network extended more distally and was densest around the scar line in Group 2. Vascularization was poorest in Group 4. On histological examination, the number of vessels tended to be greatest in Groups 3 and 4 but this was not significantly different between groups (p < 0.05). Conclusion: The study findings showed that it may be possible to raise a flap from a previously mutilated site secondary to scar formation and multiple full-thickness traumas along the flap body. However, distal necrosis may occur in situations when the scar is positioned in the middle region of the prospective flap.

In addition to precautions taken with perioperative surgical techniques, nasal packing and external nasal splinting are frequently employed to ensure the stability of the nasal bones following osteotomies performed during rhinoplasty. However, despite these precautions, nasal bone fragments, generally caused by trauma or healing problems, can approach the midline, progress in a posterior direction and heal with malunion in an infractured manner. Since cavities on the infractured side can result in asymmetries and/or airway narrowing, revision osteotomy is required to correct these problems. Subsequent potential recurrent infractures caused by nasal fragments can easily be prevented with late-absorbed sutures passing through the neighboring holes and opening near the osteotomy lines. This technique would be useful for both primary and secondary rhinoplasty, but especially in secondary rhinoplasty operations. (Level of Evidence: Level IV)

BACKGROUND: Cross leg free flaps are one of the salvage methods used for free tissue transfer in large tissue defects in the absence of recipient vessels. The fasciocutaneous flap above the posterior tibial artery can be harvested to protect the pedicle and to advance a distance to wound, which is equal to the length of fasciocutaneous flap. METHODS: Patients who were operated with cross leg free flap with the supporting fasciocutaneous flap on unwounded side were included in the study between years 2010 and 2020. Age, sex, location and size of the defects, arterial patencies, flap choices, fasciocutaneous flap size, duration of operation, cross flap separation timing, complications, and time to return to work were evaluated. RESULTS: There were six patients with the etiology of high-energy electrical burns and trauma. There was only one arterial refilling for three patients and no refilling for others. Latissimus dorsi skin muscle flap was used in all but one patient. The mean defect size was 6.6x14.8 cm. The mean size of fasciocutaneous flaps was 4.08x5 cm. The mean operation time was 360 min. There was no complication except one dehiscence and one marginal necrosis and infection which were healed with wound care. Average time to return to work was 9 months. CONCLUSION: In similar cases, as wounded lower extremities with one or no artery refill, harvesting a fasciocutaneous flap with recipient vessels will be useful before considering the option of using a bridge free flap in medium to moderate sized defects.

Background/aim: Human Demodex mites are parasites that live in the pilosebaceous unit and can cause demodicosis. While demodicosis may occur as a primary skin disease, it may also result from immunosuppression and topical or systemic immunosuppressive therapies. Surgical rhinoplasty is one of the most commonly performed cosmetic procedures, and it is the cause of a variety of cutaneous complications, particularly acne, as it affects the skin's adnexal structures. Thus, this study aimed to investigate whether the cutaneous changes in surgical rhinoplasty patients render them vulnerable to Demodex infestation. Materials and methods: Individuals who had undergone rhinoplasty (patients) and age- and sex-matched healthy volunteers (controls) were included in this prospective case-control study. To determine the Demodex density, samples were collected from the malar and nasal regions of both the patients and controls using the standard superficial skin biopsy method. Results: A total of 50 rhinoplasty patients and 50 healthy controls were enrolled in the study. The Demodex density on the nose was significantly higher in the rhinoplasty patients (p = 0.0001). Furthermore, the frequency of xerosis and pustules was significantly higher in the rhinoplasty patients compared to the control group (p = 0.046 and p = 0.001, respectively). Conclusion: Surgical rhinoplasty may be a risk factor for demodicosis, and patients will recover faster after surgery with proper diagnosis and treatment.

Background Keloid is a dermal fibroproliferative disease unique to humans. Due to the ambiguity in its pathophysiology and the frequent recurrence of keloid, there is no clear consensus on the treatment of keloid and there are many treatment methods defined. In order to benefit from the positive effects of fat grafting on pathological scars, we applied fat grafting to patients who underwent keloid enucleation. Methods Fifteen ear keloid patients included in the study. All patients underwent the same surgical procedure by the same surgeon. Routine follow-ups and examinations were performed to evaluate the results and in addition, the Patient and Observer Scar Assessment Scale (POSAS) survey was used. Results In the study, 15 patients were followed for a median (IQR) period of 21 (13–28) months. No recurrence was observed in any patient during follow-up, which occurred for a median of 21 (13–28) months. In the questionnaire filled out by the patients, the preoperative median value was found to be 48 (IQR: 12), whereas the postoperative median value was found to be 14 (IQR: 8). According to the patients, there was a statistically significant (P < 0.05) positive improvement after surgery. Conclusions Historically, surgical procedures were avoided because the surgical recurrence rate was very high, but today, recurrence rates are decreasing with combined treatments. These treatment combinations may require more than one intervention and require frequent clinical follow-ups. With our technique of fat grafting after enucleation, the treatment was completed with a single operation and no additional intervention was required.
