RESUMO
OBJECTIVE: Creation of the upper pole fullness is one of the basic goals in reduction mammaplasty. The superior pedicle (S-P) technique brings extra tissue to the upper pole, but folding of a long pedicle can compromise circulation of the nipple-areola complex (NAC). Although the pedicle is not folded in superomedial pedicle (SM-P) technique, it has disadvantage of not bringing extra tissue to the upper pole. We designed a new approach by combining the advantages of S-P and SM-P techniques. Thereby, we aimed to increase upper pole fullness in SM-P or superolateral pedicle (SL-P) mammaplasty. METHOD: We operated 20 female patients (study group) with the modified SM-P/SL-P technique for breast reduction between 2010 and 2022. Preoperatively, mean sternal notch-nipple distance was 32.6 ± 2.5 cm. The upper pole fullness was created by using a superiorly based glandular flap, while the SM-P (17 patients) or SL-P (three patients) was used to carry the NAC. We assessed the success rate of the upper pole fullness, compared with two control groups of 40 patients who underwent conventional SM-P mammaplasty (control group I: 20 patients) and who underwent conventional S-P mammaplasty (control group II: 20 patients). Two plastic surgeons, who do not know which technique was used, assessed before and after photographs of 60 patients regarding success rate of upper pole fullness. To evaluate the success rate, the degree of the difference in the upper pole fullness between before and after photographs has been scored 1-10 for each patient. Below 5 was considered as no difference (unsuccessful), 5-7 as moderate difference (average), 8-10 as significant difference (successful). Photographs of the patients had been taken from five different angles: frontal, right and left oblique views, and right and left sides. RESULTS: Out of 10, mean score was 8.2 ± 1.2 in study group, 7.1 ± 1.8 in control group I, 8.2 ± 1.5 in control group II. Postoperatively, no major complications were observed, such as glandular necrosis, total NAC necrosis, partial (> 50%) NAC necrosis, skin necrosis, or poor NAC sensitivity in none of 60 patients. CONCLUSION: By using this modification, it is possible to increase upper pole fullness in SM-P/SL-P mammaplasty.

RESUMO
Plexiform neurofibroma is a benign peripheral nerve-sheath tumor, rarely involving major nerves of the extremities. In the literature, there are no clear treatment strategies for plexiform neurofibroma of major peripheral nerves. Our experience encountered two patients with plexiform neurofibroma of the median nerve, presenting with a palmar mass and symptoms of carpal tunnel compression. Preoperatively, plexiform neurofibroma was diagnosed on MRI and clinical examination. Both patients also experienced significant neurological deterioration, with finger numbness and increased nerve/tumor size. Potential malignant transformation was also considered. For these reasons, resection of the involved area of the nerve and repair were indicated. In both patients, intraoperative pathological diagnosis was plexiform neurofibroma. The 45-year-old male patient refused further surgery after carpal tunnel release, which was performed under axillary block. One year postoperatively, nerve compression symptoms decreased moderately. In the other patient, a 7-year-old boy, a significantly enlarged area of the median nerve was resected, and neurorrhaphy was performed. One year postoperatively, median nerve motor-sensory functions recovered completely. Four years postoperatively, no enlargement of the residual tumor was observed.

INTRODUCTION: This study investigated the effect of periosteal graft + platelet-rich plasma (PRP) combination on facial bone defect healing. METHODS: Five-millimeter critical sized defects in zygomatic arches of 12 adult New Zealand rabbits were created. Rabbits were randomly divided into 3 groups: First group (control group): bone defects of left zygomatic arches of 6 rabbits were wrapped with a silicone tube. Second group (periosteal graft group): bone defects of left zygomatic arches of 6 rabbits were wrapped with periosteal graft. Third group (experimental group): bone defects of right zygomatic arches of 12 rabbits were wrapped with periosteal graft-PRP combination. New bone formation was evaluated at 8th and 16th weeks. One rabbit was sacrificed at 8th week. Remaining 11 rabbits were imaged with 3-dimensional computed tomography (CT) at 16th week; then, zygomatic arches were removed for micro-CT and histologic examinations. RESULTS: Three-dimensional CT analysis at 16th week revealed no significant difference between groups regarding new bone formation (P = 0.232). Micro-CT analysis of new regenerated bone at 16th week displayed significant differences between groups 1 and 3 regarding mean bone volume (BV, mm) (P = 0.028) and mean bone mineral density (BMD, mm) (P = 0.001). There was no difference between groups 2 and 3 or between groups 1 and 2, regarding BV or BMD. Histological Bone Regeneration Scorings at 16th week displayed significant difference between groups (P = 0.015). Negative correlation between 3-dimensional CT and histologic results (r = 0.120); positive correlations between BV/BMD values in micro-CT and histologic results (r = 0.524 and r = 0.456) were found. CONCLUSIONS: By enhancing bone formation capacity of periosteal grafts, periosteal graft-PRP combination provided bone formation having more volume and density comparing with silicone tube application.

INTRODUCTION: Facial bone defects are frequently encountered problems in clinical practice. Bone grafts, flaps, and alloplastic materials are often used in their treatment. This leads to donor site morbidity and prolongation of the operation. The authors have planned this study to examine whether adipose tissue derived stromal vascular fraction (SVF) has an osteogenic effect in the critical sized membranous bone defect of the zygomatic bone. MATERIALS AND METHODS: Twenty male Wistar Albino rats were used. Bilateral zygomatic arches were opened with lateral incisions. A standard 3-mm bone defect was created bilaterally on the zygomatic arches of the rats. In the experiment side, the stem cell-rich SVF that was obtained by applying centrifugal process to the adipose tissue derived from the inguinal fat pad was injected into the site of the right zygomatic arch bone defect. In the control side, left zygomatic arch was left for secondary bone healing without any treatment after a 3-mm critical bone defect was created. In the postoperative 10th (n:5) and 20th weeks (n:13), the healing areas of bone defects were assessed by a 3-dimensional tomography, and then, the rats were sacrificed and bone healing was examined histologically. RESULTS: There were no statistically significant differences on the 10th week results. At the 20th week new bone formation amount calculated from the 3-dimensional computed tomography results was significantly higher in the experiment side (Pâ=â0.033). In the histological examination at the 20th week, there was significantly more callus formation in the experiment side (Pâ=â0.0112). DISCUSSION: Stem cells can increase the rate of bone healing by differentiating into certain tissues. It is predicted that adipose tissue-derived SVF rich with mesenchymal stem cells can increase bone healing in facial bone defects and this application could replace the use of bone grafts and flaps in clinical practice. As a result, it is concluded that adipose tissue-derived stem cells can potentiate osteogenesis and reduce the possibility of developing necrosis on the bone ends.

BACKGROUND: Trigeminocardiac reflex (TCR) consists of bradycardia or asystole along with hypotension and apnea coinciding with stimulation of the trigeminal nerve. During rhinoplasty procedures, we noticed that local anesthetic solution (LAS) application to the columellar area results in bradycardia. We planned to conduct a randomized prospective study on 47 patients undergoing rhinoplasty to demonstrate the characteristics of TCR arising from the columella. METHOD: Local anesthetic solution containing 2% prilocaine with 1:80,000 adrenaline was applied under standard general anesthesia protocol. In group 1 (study group, n = 24), 2 mL of LAS was applied to the columella. In group 2 (control group, n = 23), 2 mL of LAS was applied to the nasal dorsum. In group 3 (control group, n = 20), after LAS was applied to nasal dorsum in group 2, we waited for 10 minutes. Then, 2 mL of LAS was applied to the columella. Here, recordings were taken for the columella.Heart rate (HR) and blood pressure (BP) were recorded just before needle insertion (baseline level), at the time of needle insertion (NIT) to the columella or dorsum, and after the 1st, 5th, 10th, 30th, and 60th seconds. RESULTS: Transient bradycardia (≥20% drop in HR) was observed in 33% of the patients in group 1.Decrease in HR compared to the baseline level in group 1 was significantly greater than that of groups 2 and 3 at all times (P ≤ 0.05).Systolic BP in NIT and in 60th second in group 1, only in NIT in group 2 was significantly lower than that of baseline levels (P ≤ 0.05). CONCLUSIONS: We concluded that stimulation of a sensory branch of the trigeminal nerve in the columellar area leads to TCR under general anesthesia by eliciting clinical hypotension with a drop in systolic BP and in HR of more than 20% compared to the baseline level.Knowing the existence of a certain TCR area will be helpful to the surgeon and anesthesiologist to exercise extra vigilance and to make continuous and meticulous monitoring of the electrocardiogram, HR, and BP during which the TCR may be precipitated such as local anesthetic infiltration to the columellar area in rhinoseptoplasty operations.

Occipital condyle fractures are rare, and conservative treatment is sufficient for many cases. Surgical treatment may be required if the condyle fracture is accompanied by atlantooccipital dislocation. Unfortunately, condyle fracture generally cannot be diagnosed with X-ray in the emergency department. Recently, computed tomography scans have been used more frequently, and enable easier diagnosis of these types of fractures. In this report, we describe a patient who admitted to our emergency department after a major trauma. She complained of neck pain, and maxillofacial trauma was more evident. Her cervical X-rays were normal, but cervical computed tomography revealed unilateral occipital condyle fracture.

Proliferating trichilemmal (pilar) cysts, also known as pilar tumors, are most commonly found on the scalp of elderly women. Proliferating trichilemmal cysts are rare, slowly growing, lobular masses inherited autosomal dominantly and localized on scalps, and believed to arise due to a complication of a trauma and inflammation, and 5-10% of people are reported to be effected. Herein, we present the case of a 70-year-old woman with a 23-year history of multiple enlarging scalp masses. Clinically, squamous cell carcinoma was considered in the differential diagnosis, and the lesion was totally excised. Our case emphasizes the necessity for detailed clinical and pathological correlation for differential diagnosis.

BACKGROUND: Proximal phalanx fractures are common. In this study, our preferred methods regarding the treatment of proximal phalanx fractures and their long-term objective results are presented. METHODS: Between October 2001 and March 2010, in the Plastic Reconstructive and Aesthetic Surgery Department of Düzce Medical Faculty, we treated 23 patients with 32 proximal phalanx fractures. Stable fractures (n=5) were treated with splints, while unstable fractures (n=27) were stabilized with 1.0 mm percutaneous intramedullary Kirschner wires following open reduction. RESULTS: At follow-ups, ranging from 3 months to 9 years, patients were evaluated with radiologic efficiency, range of motion (ROM), total active movements (TAM), and grip power of the digit. TAM scores of 20 fingers were perfect (≥220° for D2-5, ≥150° for D1), for 7 fingers were good (180- 220° for D2-5, 120-150° for D1), and for 5 fingers were either moderate or poor. No difference was observed between grip strength of broken fingers and that of healthy fingers. As a major complication, non-union occurred in one finger. CONCLUSION: We concluded that Kirschner wire fixation is a reliable and simple method of treating unstable proximal phalangeal fractures, and excellent long-term results can be obtained in suitable cases. In stable proximal phalanx fractures, splints provide sufficient treatment.

Total ear amputation is common, and management can necessitate different procedures, especially microsurgical anastomosis. Partial ear amputations supplied by narrow pedicles, however, have been reported rarely. In a subtotally amputated auricle, the chance of survival depends on the vascularization within the pedicle. In our case, the right ear of a 36-year-old male patient was subtotally amputated following a traffic accident, leaving only a 6-mm skin pedicle on the cranial side. The subtotally amputated segment was bleeding from the wound margins. The ear was reattached with primary suture without using microsurgical techniques after optimal debridement. Postoperatively, we administrated dextran 40 for 5 days to improve the microcirculation and increase blood volume and antibiotic to control the infection. No signs of edema, venous congestion or arterial insufficiency were observed immediately after the operation or subsequently. The replanted auricle healed completely with 100% survival, resulting in an essentially normal contour and appearance. This successful result without microvascular anastomoses also points out the anatomical features of the auricular vascular networks.

A 48-year-old female patient presented with gigantomastia. The sternal notch-nipple distance was 55 cm for the right breast and 50 cm for the left. Vertical mammaplasty based on the superior pedicle was performed. The resected tissue weighed 3400 g for the right breast and 2800 g for the left breast. The outcome was excellent with respect to symmetry, shape, size, residual scars, and sensitivity of the nipple-areola complex. Longer pedicles or larger resections were not found in the literature on vertical mammaplasty applications. In our opinion, by using the vertical mammaplasty technique in gigantomastia it is possible to achieve a well-projecting shape and preserve NAC sensitivity.

OBJECTIVE: We report that a 4-year-old boy presented with right unilateral complete cleft lip and palate, right anophthalmos, left congenital nystagmus, absence of the vomer bone, mental-motor retardation, and normal lymphocyte karyotype (46, XY). METHODS: For reconstruction of the deformities, we performed cleft lip repair by Millard's rotation-advancement technique and planned cleft palate repair. CONCLUSIONS: This combination of cleft lip and palate, anophthalmos, congenital nystagmus, absent vomer bone, and mental-motor retardation has not, to our knowledge, previously been described. We suggest that this represents either another case of the rare Fryns "anophthalmia-plus" syndrome or a new syndrome.

AIM: To investigate the feasibility of the autologous fascia graft in urethra defect reconstruction. METHODS: In 24 adult male rabbits, a standardized defect (17 mm) was created within the midportion of each urethra. Two-cm long fascial tube grafts were interposed between the cut ends of the urethra. Twenty-four rabbits were divided into 12 groups. At 0, 3, 10, 15, 21, 30, 45, 60, 90, 120, 150, and 180 days postoperatively, one group was killed. In the first four groups, rabbits were killed and specimens were obtained for histological examination. After 21 postoperative days, in the subsequent eight groups, retrograde urethrograms were carried out to evaluate urethral patency and caliber, then rabbits were killed and specimens were obtained. RESULTS: In the histological study, advancement of the urethral transitional epithelium along scaffold provided by the fascial graft was determined. At the 30th day, the new urethra was completely covered with the transitional epithelium. Fistula formation was observed in two of 24 rabbits. In urethrograms, narrowing was determined in three of 16 rabbits. CONCLUSION: For segmental urethral reconstruction, fascial graft is a good urethral substitute because of its rapid epithelization capacity, low contraction degree and thinness. We therefore propose the use of fascial grafts for reconstruction of male-urethra defects in humans.

The large myelomeningocele defects that cannot be closed reliably by simple skin undermining require a close cooperation between the neurosurgeon and the plastic surgeon. In this study, a 3-year review was undertaken of nine consecutive patients with a myelomeningocele defect treated in our hospital. The aim of the study was to analyze the size, location of myelomeningocele defects, features of the surrounding tissue, and type and results of the reconstruction method for skin closure. Of the nine patients, five were repaired within the first 48 h of life, two within the 1st month of life, and two were repaired within the 1st year of life. Of the nine patients, seven (78%) underwent repair with direct skin approximation by the Neurosurgical Service. For three patients (33%) with large lumbosacral meningomyelocele defects, including one patient who had failed direct skin approximation, the Plastic Surgery Service achieved the skin closure by bilateral paralumbar fasciocutaneous rotational flaps. Minimal area in the patients referred to the Plastic Surgery Service was 24 cm2 (range 24-48 cm2); patients having 18 cm2 or less skin defect were not referred for closure. In conclusion, fasciocutaneous rotational flaps provided tension-free, durable, innervated and well-vascularized skin coverage over the dural repair in all three referred patients, without using skin graft. Since myelomeningocele defects vary in size, shape, and location, no single procedure applies to all. Therefore, other reconstruction methods involving skin grafts, fasciocutaneous flaps, and musculocutaneous flaps are reviewed in this report.

Complex maxillofacial fractures demand a detailed understanding of the three-dimensional (3D) pattern of injury. Evaluation of the outcome of the facial fracture repair additionally requires optimal demonstration of fracture gap, bony union, fibrous callus or incorporation of fracture ends, presence of incomplete fusion, or pseudoarthrosis. Although 3D computed tomography (CT) is reliably used for the diagnosis of complex facial fractures, its value in facial fracture healing is unknown. An experimental study was conducted to determine the accuracy of 3D spiral CT scans in evaluating facial fracture healing during the early and late postoperative periods. In 10 adult Wistar Albino rats, a standardized bone defect (3 mm) was created within the mid portion of each zygomatic arch (n = 20). At 10 and 20 weeks postfracture, gap distance displayed by 3D CT and plane radiography (posteroanterior) were measured. At 20 weeks postfracture, intraoperative measurement was also performed. A comparison between 3D CT, radiography, and intraoperative findings was performed. At 10 weeks postfracture, the fracture sites displayed larger bone defects in imaging with 3D CT than with plane radiography. The difference between groups was statistically significant (P < 0.05). The mean defect size imaged by 3D CT was 0.91 +/- 0.82 mm (standard deviation) and by plane radiography was 0.42 +/- 0.16 mm. At 20 weeks postfracture, the mean defect size imaged by 3D CT was 0.56 +/- 0.64 mm, and by plane radiography was 0.38 +/- 0.22 mm. The difference between groups was not statistically significant (P > 0.05). The defect size imaged by both plane radiography and 3D CT was significantly less than the measurement obtained from the intraoperative assessment (P < 0.05). It was concluded that 3D CT has limited benefit in the detection of newly formed bone at week 10 and in the detection of fibrous callus, which can eventually give rise to the bony tissue. Plane radiography is more valid during the early postoperative period (week 10), because it can detect the fibrous callus and newly formed bone more precisely. Gap distance between fracture ends could be determined by 3D CT accurately at week 20, although there was a tendency, which was not statistically significant, to overestimate the amount of bone defect measured by 3D CT when compared with that of plane radiography.

In surgical treatment of head and neck cancer, when local tumor recurrence or failure of the previous reconstruction method occurs, reoperation for reconstruction of complicated soft-tissue defects can become a challenge for the plastic surgeon. This article describes the authors' experience with the extended vertical trapezius myocutaneous flap for head and neck complicated soft-tissue defects in nine patients ranging in age from 17 to 72 years. The causes of the defects were squamous cell carcinoma of the external ear (n = 2), lip (n = 2), larynx (n = 1), and oral cavity floor (n = 1); congenital hemifacial atrophy-temporomandibular joint ankylosis (n = 1); synovial sarcoma at the mandibular ramus (n = 1); and malignant fibrous histiocytoma at the posterior cranial fossa (n = 1). Eight of the nine patients had previously been operated on using other flap procedures, including free flaps and/or distant pedicled flaps (pectoralis major and deltopectoral flaps). One patient had been operated on using a graft procedure. After failure of the previous flap procedures in four patients and tumor recurrence in five patients, the extended vertical trapezius myocutaneous pedicled flap was used as a salvage procedure. The mean flap size was 7 x 34 cm. The flap was based solely on the transverse cervical artery. Superior muscle fibers of the trapezius were preserved and the caudal end of the flap was extended from 10 to 13 cm beyond the caudal end of the trapezius muscle. Three weeks postoperatively, the pedicle was separated. No flap failure occurred. The donor sites were closed primarily. There were no disabilities with regard to shoulder motion. Tumor recurrence was observed in two patients. In conclusion, for complicated soft-tissue defects of the head and neck, the extended vertical trapezius flap can be preferred as a salvage procedure because it is a simple, reliable, large flap that is located far enough from the damaged area.
