RESUMEN

Free anterolateral thigh flap (ALT) and latissimus dorsi myocutaneous flap (LDMF) are well-defined flaps frequently used to reconstruct head and neck defects. Our study aimed to compare the advantages and disadvantages of these flaps regarding esthetics, complications, and cost burden. The authors retrospectively evaluated 10 patients who applied to our clinic between January 2016 and December 2021 and required free flap reconstruction for the defect in the head and neck region. The first group consisted of 5 patients with ALT flaps, and the second group had 5 patients with LDMF flaps. The average cost burden of the first group was calculated as 18,373 TL, and the second group's was 23,362 TL. Our study found that the cost and complication rates were statistically higher in the LDMF flap group, and using an ALT flap was more reasonable due to its advantages.

RESUMEN

ABSTRACT: Accessory breast tissue is a relatively common variant of ectopic breast tissue. It defines a tissue that can be seen in conjunction with a nipple, areola, and underlying glandular tissues and can develop in addition to the normal breast tissue. While swelling may be accompanied by symptoms such as pain that worsens with the menstrual period, lactation, and limitation of shoulder joint movements, aesthetic concerns also constitute an important part of the surgical needs of patients. An 18-year-old patient without any known comorbidities attended because of a developmental disorder in her left breast that has existed since birth and an accessory breast tissue containing the nipple and areola in the upper-outer quadrant of the left breast. The surgical aim was to excise the patient's accessory breast tissue and ensure symmetry, and a two-stage surgical intervention was planned. In the first stage, the accessory breast tissue in the upper-outer quadrant of the breast was transposed preserving the 2nd and 3rd Internal Mammary Artery-based perforators by passing it through a subcutaneous tunnel and folding it in its ideal place. At second stage, the reduction mammoplasty surgery was performed on the right breast to ensure symmetry with the left breast, and resection was performed on the nipple in the middle lower quadrant of the left breast. At the end, acceptable symmetry and patient satisfaction were achieved.

RESUMEN

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.

RESUMEN

Pyrethroids (PYRs) may act as endocrine disrupters and lead to infertility. The aim of the study was to analyze the levels of anti-androgenic PYRs (cypermethrin, deltamethrin, and permethrin) and 3-phenoxy benzoic acid (3-PBA), a general metabolite of PYRs, in both semen and urine samples of men with oligozoospermia. The PYRs and 3-PBA metabolite levels in the semen and urine samples of the men were analyzed through GC-MS. The results indicated that the levels of PYRs in the semen samples of the infertile group were significantly higher than those of the fertile group. It was determined that cypermethrin exposure was associated with changes in sperm count and total sperm motility, while permethrin, deltamethrin, and 3-PBA levels were associated with changes in sperm morphology. It was determined that there was a significant negative correlation between semen deltamethrin levels and sperm morphology and sperm count. In addition, exposure of these patients to deltamethrin (range; 1.53-8.02 µg/l) and having farmer parents were determined to increase the risk of infertility. In conclusion, the findings of this study showed that exposure to environmental PYRs may adversely affect semen quality, especially in terms of sperm morphology, in men with oligozoospermia.

RESUMEN

Frey syndrome is still a significant problem in postparotidectomy patients 6 to 18 months after surgery. The most accepted theory of the pathogenesis of Frey syndrome is the aberrant regeneration theory. Creating a barrier between the remnant parotid gland and the overlying skin prevents Frey syndrome. A 51-year-old female patient who developed pleomorphic adenoma in the parotid gland was operated. After superficial parotidectomy, a barrier between the underlying postganglionic parasympathetic nerves in the deep parotid gland and the overlying cutaneous tissue was created with a local skin flap to prevent Frey syndrome. The patient was successfully treated, and she was followed up to 5 years. No postoperative complications were observed. No signs of Frey syndrome were found in follow-up. This case highlights that local skin flaps can be an innovative natural method as it is a quick and simple method to create this barrier in the presence of expanded skin.

RESUMEN

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, fascio-cutaneous 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 6.6×14.8 cm. The mean size of fasciocutaneous flaps was 4.08×5 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.

RESUMEN

BACKGROUND: The purpose of this study was to investigate the use of tissues with multiple traumas, scarred pedicles, and medial scarring as a flap. 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). DISCUSSION: 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.

RESUMEN

Osteoseptocutaneous fibula flap is commonly used as the workhorse flap for bone reconstruction. However, the use of previously fractured fibula as a free or pedicled flap for bone reconstruction has a limited knowledge in the literature. There is not any data in the literature about a case with proximal level of fibula fracture which was used as an anterograde pedicled osteocutaneous fibula flap for composite tibial reconstruction after high-energy injury. Based on a patient in whom the composite defect of the proximal tibial region was reconstructed with osteocutaneous fibula flap after a gunshot injury, it was tried to show that the fibula with a proximal level fracture could be used with anterograde flow in the subacute period and it is thought that the usability of this flap should be kept in mind. It is possible to harvest the pedicled fibula flap even in the subacute period with the evaluation of CT angiography preoperatively and with the checking the patency and flow direction of peroneal artery perioperatively. The success of the procedure may be increased through total dissection of inflammatory areas of pedicle which would extend into the injury zone during the subacute period.
