Profunda femoris artery perforator flaps: a detailed anatomical study.

The thigh region has many perforators when compared to the other areas in the body. Surgeons have disregarded the posterior thigh region as a potential donor site for perforator flap surgeries, presumably owing to the positioning difficulties of the patients during the intervention and inadequate anatomical information. The purpose of this study was to provide comprehensive data concerning the profunda femoris artery. Perforator flaps on an anatomical basis, and to describe anatomical landmarks, easing topographical flap dissection in various combinations. Eleven fresh cadaver thighs were obtained from different individuals using the Willed Body Program. The mean age was 43.5 years (29-63), and the male/female ratio was 7/4. We evaluated each cutaneous perforator for localization, diameter, source artery, numbers, length, and type (musculocutaneous or septocutaneous).We observed at least two perforators in all thighs in the study. Medial perforators consisted of 74.5% musculocutaneous and 25.5% septocutaneous perforators. Lateral perforators consisted of 68.3% septocutaneous perforators and 31.7% musculocutaneous perforators. Positioning difficulties of the patient during surgery and inadequate anatomical information cause surgeons to avoid this area. However, surgeons may easily perform these flaps in reconstructive surgery as a local or free flap with substantial success.

A novel method for flap delay vacuum assisted flap delay: an experimental study in rabbits.

Flaps are the workhorse of plastic surgery practice. The delay procedures have been defined to prevent flap necrosis. The golden standard method of delay is a surgical delay. On the other hand, a major drawback of surgical delay is two sessions of surgery. Efforts have been made to omit one session and increase the patient safety and decrease the costs. The writer's aim was to evaluate the effects of topical negative pressure, applied prior to flap elevation, on flap survival, perfusion and compare the results with the surgical delay. In a rabbit random flap model, prior to elevation, the writers used a topical negative pressure system on the lateral thoracic region of, for induction of delay and compared the results with surgical delay and the control group. The total and necrotic flap areas, necrosis ratio, histomorphometric vascular density, immunohistochemical evaluation of neovascularization (CD31/CD34), Laser Doppler images and computerized tomography contrast uptake were used to compare the groups. In all of the parameters, the vacuum assisted flap delay was equivalent to surgical delay. Both were superior to non-delayed flaps. Control group had 65.56 ± 18.02% flap necrosis rate, while Surgical Delay group had 37.31 ± 30.74% and Vacuum Assisted Flap Delay group had 19.58 ± 27.35%. Vacuum Assisted Flap Delay did not require an extra operation for the delay procedure. The mechanism of action in the vacuum-assisted flap delay is unclear. The clinical significance should be studied further. However, vacuum assisted flap delay seems to be a promising method in the clinical setting.

Experiences with a modified preauricular mini incision with subdermally dissection in condylar and subcondylar fractures of the mandible.

OBJECTIVE: Condylar and subcondylar fractures (CSFs) are among the most common mandible fractures. If reduction of these fractures is not carried out correctly, serious complications can result, including infection, damage to temporomandibular joint (TMJ) function, malocclusion, nonunion, malunion, and ankylosis of the TMJ. METHODS: We used a preauricular, mini-incision, open technique (PMIOT) for CSF of the mandible. 66 patients (48 males, 18 females), with a total of 72 CSFs of the mandible, were repaired with PMIOT between 2011 and 2016. Average age was 37.8 years (range: 8-78). CSFs were located on the right side, left side, and bilaterally in 21, 27 and six patients, respectively. We used only one mini incision of length 2 cm for non-displaced subcondylar fractures. However, we had to perform a second mini incision for condylar fractures displaced by more than 45°, where subcondylar fractures overlapped, or where there was deep surgical exposure and difficulty with reduction. RESULTS: No early complications, such as bleeding, hematoma, seroma, infection, or parotid fistula, were seen in any patients. Temporary facial nerve paresis was reported in three patients, but these recovered spontaneously with conservative treatment within 15 days. Permanent facial nerve paralysis occurred in none of the patients. CONCLUSION: We believe that PMIOT is an effective, reliable, and feasible method for repair of CSF. It does not need any expensive and sophisticated tools, and has low complication rates. The mini incision used in our technique results in both a hidden scar and protection of essential structures in the region.

Chimeric Reverse Temporal Muscle and Pericranial Flap for Double-Layer Closure of Deep Facial Defects.

PURPOSE: Volumetric or multiplane defects of the upper and midface remain a challenge for reconstruction because of limited regional flap options. In this study, the authors harvested the reverse temporalis muscle flap and pericranial flap (RTMP flap) based on the same vascular pedicle, the superficial temporal artery, in a chimeric manner to obtain double-layer closure of deep facial defects. MATERIALS AND METHODS: This study was a prospective case series performed in the Department of Plastic Surgery of Ataturk University (Erzurum, Turkey). The outcomes, including flap survival, postoperative complications, reconstructive success, esthetic appearance, and donor site morbidity, were clinically evaluated. RESULTS: Fourteen patients (10 male and 4 female) with deep defects of the middle third of the face underwent reconstruction using the chimeric RTMP flap. All chimeric RTMP flaps survived without postoperative complications. All defects were successfully repaired and covered with chimeric RTMP flaps. Patients were satisfied with the esthetic results. CONCLUSION: The chimeric RTMP flap is a good reconstruction option and can be used safely for moderate to large 3-dimensional defects of the middle and upper face. Smooth and durable coverage over the bulky muscle flap used to fill the volume defect and a larger flap for larger volume defects can be obtained by including the pericranial segment of the chimeric RTMP flap.

The Temporal Artery Island Flap: A Good Reconstructive Option for Small to Medium-Sized Facial Defects.

PURPOSE: The reconstruction of facial defects is esthetically vital because of the unique skin color and texture of the face. The aim of this study was to show the utility of different temporal artery island flap designs for the reconstruction of upper and middle facial defects without contrast to the color and texture of the face. MATERIALS AND METHODS: This study is a retrospective case series conducted from November 2004 through May 2015. Patients older than 18 years with upper and middle facial defects smaller than 5 cm were included. RESULTS: The temporal artery island flap was used in 34 patients (21 men and 13 women). The etiologies were skin tumor in 17 patients, trauma in 10 patients, and burns in 7 patients. Major defect localization was in the temporal area in 12 patients, followed by the ear in 9 patients, the cheek in 6 patients, the eyebrow in 4 patients, and the nose in 3 patients. Flap designs consisted of the antegrade-flow island flap, the V-Y flap, and reverse-flow island flap in 23, 7, and 4 patients, respectively. All flaps survived completely except for 1 partial flap necrosis. Scars in the donor areas were inconspicuous. Patients' median age was 47.5 years (quartiles, 40.75 to 54), 61.8% were men, and median duration of follow-up was 11 months (range, 6 to 18 months). CONCLUSIONS: The temporal artery island flap could be a good option for the closure of minor to medium-size defects of the upper and middle face because of its good color and texture match, constant and reliable pedicle, wide pivotal movement, low donor site morbidity, and reverse-flow pattern.

Management of Saddle Nose Deformity Using Dermal Fat and Costal Cartilage "Sandwich" Graft: A Problem-Oriented Approach and Anthropometric Evaluation.

PURPOSE: In the surgical treatment of saddle nose deformity (SND), costal cartilage is often used. However, it can result in some potential complications such as resorption, bending, displacement, and its appearance under the skin (silhouette deformity). We prepared a composite "sandwich" graft by camouflaging the costal cartilage underneath the dermal fat graft as a novel method and applied it on SNDs using the closed rhinoplasty technique to prevent or minimize these risks. MATERIALS AND METHODS: The method was used for 21 patients (12 males and 9 females). Six anthropometric measurements, including the nasal dorsum projection, nasal supratip projection, nasal tip projection, nose length, labiocolumellar angle, and nasofrontal angle, were taken using the ImageJ program (National Institutes of Health, Bethesda, MD) on preoperative and postoperative lateral photographs. The data were compared statistically. RESULTS: The mean follow-up time was 29.95 months. No donor site complications developed. The sandwich grafts transferred to the nose were well tolerated in all patients. A partial graft failure and a mild bending, which were treated conservatively without supplemental surgery, developed in 1 patient each. No resorption, migration, bending, or appearance under the skin of the sandwich grafts were seen in the remaining patients. A statistically significant difference was found in all anthropometric measurements from the preoperative and postoperative groups except for 2. CONCLUSIONS: The severity of the deformity should be exactly determined before surgery, and cartilage grafts should be used accordingly for successful repair of SND. The sandwich technique, as a practical, effective, and long-lasting treatment method, could minimize the potential complications and risks of revision.

Reconstruction of the Wide Scalp Defects Using Free Latissimus Dorsi Flap Assisted With Arteriovenous Loop.

Reconstructions of the wide scalp defects are still a challenging task because of the accompanied recipient vessel issues. Arteriovenous loop (AVL) grafts are a suitable vascular conduit that can be used to support free tissue transfer, when adjacent blood supply is inadequate. We report 2 patients of successful wide scalp reconstruction, using a free latissimus dorsi (LD) flap assisted with AVL. Both flaps and AVL grafts fully survived postoperatively. No complications related to the recipient and donor areas developed. The flaps obtained a durable barrier and an acceptable aesthetic appearance. We believe that AVL can be a useful adjunct for increasing the success rate of wide scalp reconstructions with inadequate adjacent arterial inflow or venous outflow. The free LD flap is a good option with its wide surface, rich vascularity and relatively low donor morbidity in such reconstructions.

Neurotized sural flap: An alternative in sensory reconstruction of the foot and ankle defects.

INTRODUCTION: The sensory reconstruction of the lower extremity is one of the main goals in lower extremity reconstruction. Reconstructive options endowing sensory recovery are limited. The aim of this report is to evaluate the neurotized sural flap in reconstruction of foot and ankle defects. PATIENTS AND METHODS: Seven cases that were operated for foot and ankle skin defects with the neurotized sural flap were reported. The largest flap was 10 cm × 14 cm in size. Median age was 38 years. Four defects were on the heel, two were on the ankle, and one was on the dorsum of the foot. The sural nerve was coaptated to a recipient nerve in seven patients. RESULTS: All flaps survived totally. Follow-up time ranged between 9 and 29 months. All cases had hot-cold perception and two-point discrimination at average 14 ± 1.63 mm at 6th month. Sensory conduction test revealed very low action potentials related to stimulation of the flap. CONCLUSION: The neurotized sural flap is a versatile modification, for the sensory reconstruction of the moderate size foot and ankle defects.

Total lower lip reconstruction using free neurotendinofasciocutaneous anterolateral thigh composite flap: a case report.

Total lower lip reconstructions are challenging procedures because of poor aesthetic and functional outcomes and limited availability of donor tissues that anatomically imitate the lip. We hereby report the free neurotendinofasciocutaneous anterolateral thigh composite flap as a new reconstructive option. A 48-year-old man presenting with a squamous cell carcinoma of the lower lip underwent wide resection of tumor, bilateral neck dissection, and lower lip reconstruction with the mentioned flap where the lateral femoral cutaneous nerve and tensor fascia lata tendon were included. No complication was encountered postoperatively. The flap survived totally. Understandable speech, oral competence, and uneventful nutrition were obtained. Furthermore, tactile, pain and heat sensations, and two-point discrimination of 12 mm at the flap were regained. In reconstruction of the lower lip, this flap was first described in the literature and can be a good candidate as a reconstructive option.

Latissimus dorsi flap harvest with a short incision.

Latissimus dorsi (LD) flap is one of the most common options utilized in reconstructive armamentarium. In this report, we present our experience on harvest of the full LD muscle flap through a short incision. Twelve free and two pedicled full LD muscle flaps were raised in 14 patients (9 males and 5 females). In this technique, an oblique incision was placed 5-7 cm caudal to axillary apex, beginning from the posterior axillary line, so as to center the neurovascular hilus. The length of incision was 10 cm in adults and 8 cm in children. Mean dissection time was 45 min. All flaps survived totally. Seroma formation developed in two cases and treated with syringe aspiration and compressive dressing. In late postoperative period, donor site scars became inconspicuous and patient satisfaction was high. Short incision technique may be a good option to overcome scar problems in donor site of the LD flap. The technique reduces the dissection time and does not require sophisticated surgical devices and skill, when compared to endoscopic LD flap harvesting from the literature.

Versatile use of the muscle and nerve sparing latissimus dorsi flap.

In this report, we describe the technique of muscle and nerve sparing latissimus dorsi (LD) flap and evaluate the outcomes of reconstruction of various defects with 12 free and 2 pedicled muscle and nerve sparing LD flaps in 14 patients. The LD muscle functions at operated and nonoperated muscles were evaluated clinically and with electroneuromyography. All flaps survived completely but one which had a partial necrosis. The mean follow-up time was 12.3 months. Adduction and extention ranges of the shoulders were the same bilaterally in all patients. In electroneuromyography, no significant difference was available statistically between the sides. This muscle and nerve sparing latissimus dorsi flap has advantages of thinness, muscle preservation and reliability, and thus can be a good option to other fasciocutaneous flaps in reconstruction surgery.

Maxillofacial fracture experiences: a review of 152 cases.

OBJECTIVE: The fractures of facial structures lead to great morbidity. Cross-sectional studies are needed to evaluate the current state of maxillofacial traumas. Thus, this study aims to evaluate these experiences and to compare these results with the current literature. MATERIALS AND METHODS: The medical records of the maxillofacial fracture cases hospitalized between January 2004 and November 2011 were examined. The age, sex, etiology, fracture localization and treatment method for each case were documented. The affected facial bones were grouped as mandible, maxilla, zygoma, naso-orbitoethmoid complex (NOEC) and blow-out. Nasal fractures were excluded. The cases were assigned to 3 groups with respect to age (below 16, above 65 and between 17 and 64). The chi Square test was used to assess the significance of the difference in mandibular fracture rates in the pediatric population compared to others. RESULTS: The total number of cases was 152. The total number of fractures was 185. Of the 152 cases, 117 were male and 35 were female. The average age was 31.4 (±18.3), ranging between 2 and 81. Thirty-one cases were 16 years old or less. Nine cases were 65 years old or more. Mandibular and zygomatic fractures were the most prevalent fractures in the adult group. Mandibular fractures were significantly more common in the pediatric age group compared to rest of the population (X(2), p<0.05). Traffic accidents were the most common etiological factor, with a 55.3% ratio. Open reduction and internal fixation was the most frequently conducted treatment modality in all age groups. CONCLUSION: Retrospective studies are important for the projection of future prospects. In summary, our results indicate that pediatric fractures are mostly in the lower face and usually affect the condylar region, which is consistent with the literature.

Evaluation of lower-limb arteries with multidetector computed tomography angiography prior to free flap surgery: a radioanatomic study.

In this study, we aimed to evaluate the vascular structures of the lower limb with multidetector computed tomography (CT) angiography and to reveal the importance of this method in preoperative planning of microsurgical transplantation. In 24 patients, lower-limb arteries were bilaterally evaluated with 16-detector spiral CT scanner in terms of patency, stenosis, or occlusion; maximal and minimal external diameters through their traces; and variations as well as length of the peroneal artery. The peroneal artery was absent unilaterally in two patients (4.3%). The mean maximal and minimal diameters were as 2.77 and 1.63, 2.92 and 1.75, and 2.72 and 1.50 mm for anterior and posterior tibial and peroneal arteries, respectively. The ranges of lengths of peroneal arteries were 50 to 117 mm. This valuable tool can provide detailed information about vascular and the remaining anatomic structures by means of its high-resolution characteristics before planning free flap surgery.

Versatile use of rhomboid flaps for closure of skin defects.

OBJECTIVE: The aim of this study is to present our clinical experience with rhomboid flaps. MATERIALS AND METHODS: Twenty-four patients who were operated on between January 2006 and October 2010 were included in the study. All defects were reconstructed using rhomboid flaps. RESULTS: Twenty-four patients were operated on for various reasons, and 26 rhomboid flaps were performed. Eleven of the 24 cases were male, and the median age of participants was 47.5 years. Eight cases were operated on under general anesthesia, and 13 were locally anesthetized; the remaining cases were operated on under regional anesthesia. In 17 cases, the defect was due to a benign or malignant tumor excision, and five cases were operated on due to burn contracture. There were no occurrences of partial or total flap necrosis or hematoma in our series. CONCLUSION: Our series indicates that rhomboid flaps can be safely used to reconstruct small to moderately sized skin defects.
