Investigating the Effect of Korean Red Ginseng on the Viability of Random-Pattern Skin Flaps in Rats.

OBJECTIVE: This experimental study investigated the efficacy of Korean Red Ginseng (KRG) extract in reducing the partial losses of random flaps. METHOD: Forty Wistar Albino rats were randomly distributed into 4 groups as (A) control group, (B) stress group, (C) oral KRG group, and (D) intraperitoneal KRG group. The modified McFarlane flap of 9 × 3 cm with a caudal pedicle was harvested from the back of the rats in all the groups. Korean Red Ginseng was administered to groups C and D at standard doses for 10 days. After 10 days, the flaps were removed in all groups and were examined macroscopically, histopathologically, histochemically, and biochemically. The results were statistically analyzed and compared among the groups. RESULTS: The flap necrosis rates were significantly lower in groups C and D compared with groups A and B (P < 0.05). The vascular density, antioxidant activity, and hypoxia-inducible factor-1α levels were significantly higher in the groups C and D compared with the groups A and B (P < 0.05). Although vascular density, hypoxia-inducible factor-1α, and catalase levels were negatively correlated with the flap necrosis rates, there was a significantly positive correlation between malondialdehyde and necrosis rates. CONCLUSIONS: Korean Red Ginseng increases the viability of random pattern skin flaps, resulting in reduced rates of distal necrosis. Korean Red Ginseng has antioxidant activity and increases neovascularization.

Platelet-Rich Fibrin Improves the Viability of Diced Cartilage Grafts in a Rabbit Model.

BACKGROUND: Diced cartilage may be wrapped with synthetic or biological materials before grafting to a recipient site. These materials have unique advantages and disadvantages, and a gold standard is not available. OBJECTIVES: The authors investigated the effects of platelet-rich fibrin (PRF) on the survival of cartilage grafts in a rabbit model. METHODS: In this experimental study, diced cartilage pieces from the ears of 9 male rabbits were left unwrapped or were wrapped with PRF, oxidized regenerated cellulose, or fascia. Specimens then were placed into subcutaneous pockets prepared on the backs of the rabbits. The animals were sacrificed 2 months after the procedure, and the grafts were excised for macroscopic and histopathologic examination. RESULTS: The cartilage graft wrapped with PRF showed superior viability compared with the cartilage graft wrapped with oxidized regenerated cellulose. No significant differences were found among the other groups. The groups were not significantly different in terms of rates of inflammation, fibrosis, or vascularization. CONCLUSIONS: PRF enhances the viability of diced cartilage grafts and should be considered an appropriate biological wrapping material for cartilage grafting.

Congenital Lateral Cleft Palate of Unknown Etiology.

The term cleft palate (CP) refers to midline defects extending from the prealveolar ark to the uvula, and these defects present with varying degrees. CP may be complete, incomplete, unilateral, bilateral, or submucosal. It is often observed with cleft lip (CL). In various studies, the incidence of isolated CP has been reported as 1.3 to 25.3 per 1000 births. As a result of deterioration of the anatomical structure of the palate, illnesses such as regurgitation, respiratory tract infections, otitis, and speech disorders may occur. These defects are often observed in the midline and are rarely laterally localized. Cleft palates with lateral localization are outside the natural midline cleft closure line and cause clinical complaints similar to other types of CP. Two cases of laterally localized CP have previously been published in the literature. The case presented here is the third known case to be reported.

Technical details of rotation palatoplasty in patients with Veau 1 cleft palate.

In cleft palate repair, elongation of the cleft toward the posterior is critically important to prevent velopharyngeal insufficiency. The purpose of many cleft palate repair techniques has been to ensure this elongation. Rotational palatoplasty is a recent cleft palate repair technique. In this technique, the soft palate is transformed into a rotational flap to allow the palate to elongate in patients with a cleft palate. This technique, which is used in all types of cleft palate and velopharyngeal insufficiency, is easy to use, practical, and efficient, especially in patients with a Veau 1 cleft palate. The aim of this study was to explain the technical details of the rotation palatoplasty technique in Veau 1 cleft palate with the aid of figures.

Technical details concerning myomucosal advancement method in the repair of large lower lip defects.

The most important decision that a surgeon has to make in large lower lip defect reconstruction is whether to use a free flap or local flap. Despite efficient transplantation, serious cosmetic problems can occur in total or in near-total lower lip reconstruction with a free flap. On the other hand, better cosmetic results can be brought about in reconstructions with local flaps when a repair is made in tissues with similar properties in terms of color, thickness, or pilosity. However, functional problems such as microstomy can be encountered when inefficient transplantation is carried out during local flap repairs. If a repair technique with local flap that enables efficient transplantation can be applied, satisfactory cosmetic as well as functional results can be provided. In this text, the technical details of the myomucosal advancement flap method, which is a successful functional local flap application with good cosmetic results, were reported and explained with the help of schematic drawings.

Comparison of the fistula risk associated with rotation palatoplasty and conventional palatoplasty for cleft palate repair.

OBJECTIVES: The aims of the cleft palate repair techniques are to reduce the velopharyngeal insufficiency risk and oronasal fistula development to minimal levels without affecting the maxillofacial development. In this article, we present a retrospective study comparing the conventional palatoplasty techniques with the new technique of rotation palatoplasty for the risk of development of oronasal fistula. MATERIALS AND METHODS: Of the 100 patients who were operated on because of cleft palate between the years 2002 and 2008, 12 patients had Furlow palatoplasty, and 88 patients received the Veau-Wardill-Kilner (V-Y pushback) operation (group C). A total of 67 patients who were operated on between 2008 and 2011 had rotation palatoplasty (group R). RESULTS: One hundred patients were men, and 67 were women. Among all the patient groups, 22.8% were classified as Veau 1, 24.6% were classified as Veau 2, 37.1% were classified as Veau 3, and 15.6% were classified as Veau 4. The rate of fistula was found to be 17.7% in all patients. Fistula development was found in 6% of the patients in group R (4/67) and in 18% of the patients in group C (18/100). The difference between group R and group C regarding the number of patients who developed fistula was statistically significant (P = 0.011). CONCLUSIONS: The Veau classification of the cleft palate affects the risk of fistula development, and the risk for fistula after rotation palatoplasty is lower than that associated with the V-Y pushback technique.

Effect of brow lifting using botulinum a toxin on upper eyelid height in patients with ptosis undergoing the frontal sling technique.

In this study, brow lifting with botulinum A toxin was performed on patients whose ptosis was corrected using the frontal sling technique, and the effects of this application on ptosis were investigated. Seven patients (with 12 eyelids) on whom the frontal sling procedure was performed using a tensor fascia lata graft were enrolled in the study. The patients underwent brow lifting using botulinum A toxin. Digital photographs of the patients were obtained before and 21 days after botulinum A injection. In digital imaging analysis, although a statistically significant elevation was detected in the eyelids and brows of the patients following botulinum A injection, it did not to lead to a significant difference in the degree of lagophthalmos. In the current study, this procedure was found to reduce the degree of ptosis without increasing the degree of lagophthalmos in patients who had previously undergone ptosis correction using the frontal sling.

Island volar advancement flap for reconstruction of thumb defects.

BACKGROUND: The volar advancement flap of the thumb described by Moberg has been used for pulp defects up to 1 to 1.5 cm since its mobility is quite limited due to the stiff nature and fibrous connections of the regional skin with underlying structures. There have been several attempts to increase the mobility of this useful flap by adding V-Y and Z-plasty concepts into the technique. These modifications could provide a slight increase in the flap advancement and achieve closure of defects up to 2 cm in length at best. METHODS: In this study, we describe the island volar advancement flap of the thumb in which all attachments, except the neurovascular pedicle of the flap, were divided to provide maximum mobility and advancement. This technique was used in 12 patients for reconstruction of traumatic defects of the distal thumb up to 3 to 3.5 cm in length. RESULTS: The flaps healed uneventfully in all patients. There was no patient with flap failure. All patients were followed up for 2 to 6 years (4 years on an average). Our results revealed sensible and durable skin coverage with maximum preservation of the thumb length. CONCLUSIONS: The island volar advancement flap seems to be a safe and useful procedure for thumb reconstruction. Providing a 1.5 cm of extra flap advancement, this new procedure enables us 1-stage closure of considerably large defects and is a critical achievement in thumb reconstruction.

Is the coexistence of intraoral synechia and cleft palate anomaly a sequence?

Intraoral synechia is a rarely seen intraoral anomaly. As a result of intraoral synechiae, fusion of the palatal shelves may be prevented because of the abnormal interposition of the tongue. Hence, cleft palate anomaly accompanies intraoral synechiae in many patients. The main problem for these patients is the inadequate oral opening for feeding. Flexible nasopharyngeal examination before intubation may help the anesthetist for simple excision of synechiae in the newborn period. In this article, a newborn who had a congenital synechia between the mandible and the maxilla has been presented, and the etiopathogenesis of intraoral synechia and the importance of flexible nasal endoscopy before endotracheal intubation are discussed.

Clinical outcomes of suture delay in forehead flap.

The delay phenomenon is a surgical procedure performed to raise a wider skin flap and to improve the survival of skin flaps. Surgery, chemicals, sutures, and lasers can be used for the delay procedure. In this study, delayed forehead flaps created by suturing were used for coverage of nasal skin defects in eleven patients. In 7 patients, the cross-paramedian forehead flap was used to increase the extent of flap lengthening. In the first session, suture delay was performed on both sides of the forehead flap margin. In the second session, the flap was elevated and sutured to its new position, 7 to 10 days after the initial surgery. All flaps were completely viable, and patient satisfaction was optimal in all cases. The positive effect of surgical delay on flap survival has been shown in experimental and clinical studies. However, experimentally, suture delay or chemical delay procedures have been shown to be beneficial in flap survival only. Suture delay seems to be an inexpensive, effective, easily performed, atraumatic, and safe technique, especially among patients with systemic diseases such as diabetes or cardiovascular diseases, smoking patients who may lose the flap, or patients who need very wide and long flaps.

Hunter's technique without Hunter's rod.

Silicon rods initially advocated by Hunter have been widely used in two-stage flexor tendon reconstruction. Two-stage tendoplasty is an expensive procedure; with the addition of the high cost of rods, it is still more expensive. An experimental study investigated cheaper alternatives to silicon rods, but no clinical studies seem to have been reported so far. This study involved 17 patients undergoing two stage flexor tendon grafting. In all fingers, silicon urinary catheters were used as tendon prosthesis. The Wehbe et al modification of the Boyes and Stark classification was used for preoperative classification and Strickland formulation and Buck-Gramcko criteria for postoperative analysis. This clinical study showed that comparable clinical results and proper pseudosheaths for tendon grafting with similar histological and physical features can be obtained using a silicon urinary catheter which is fifty times less costly than Hunter's rod.

Upper extremity injuries due to threshing machine.

BACKGROUND: The aim of this study was to report the patients who were admitted to our hospital with upper extremity injuries due to threshing machine, to determine the most appropriate classification, to estimate the treatment modalities, and to discuss the prevention methods. METHODS: Twenty-five patients who had suffered injuries sustained by a threshing machine were retrospectively investigated. The patients were analyzed with respect to age, gender, admission month, hospitalization period, the type of injured tissue, and the treatment modality. RESULTS: Twenty-four of the patients were male and one was female, and the mean age of the patients was 19.4 (2-51) years; 60% of the patients were under the age of 15. The patients were admitted most commonly in the month of August. CONCLUSION: We believe that shielding the rotating components of farming machinery that cause injuries, informing and educating farming families (by physicians), forbidding the entrance of children to areas with agricultural machines, providing information to children in schools (in those regions with developing agriculture) about agricultural accidents and their prevention methods, and adjusting the working hours of farming personnel, especially in the hottest months of the year, may be beneficial in preventing accidents due to farming machinery.

Presence of accompanying head injury in patients with maxillofacial trauma.

BACKGROUND: Patients with maxillofacial fractures are at high risk of accompanying traumatic cranial injuries. Prompt determination of head injury in these patients is crucial for improving patient survival and recovery. METHODS: The records of 246 patients with maxillofacial fractures referred to the emergency department of our hospital between January 2006 and September 2009 were reviewed in this retrospective study. The patients' age and gender, cause, type and location of the maxillofacial fracture, and the cranial injuries were analyzed. RESULTS: The mean age of the patients was 23.61±16.75 years (83.3% males and 16.7% females). Cranial injury was observed in 38 patients with maxillofacial trauma. While the risk of head injury was found to be 3.44-fold lower among patients with single facial bone fracture (p<0.001), the risk of experiencing head injury significantly increased in patients with multiple facial bone fractures (p<0.001). The risk of head trauma significantly increased in patients with fractures of the nasal bone, maxillary bone, mandibular bone, and with frontal region fractures (p<0.05 in each group). CONCLUSION: The patients with multiple facial bone fractures should be investigated with regard to head injury even if they do not have clinical findings.

Closure of large myelomeningocele defects using dorsal intercostal artery perforator flap.

Small meningomylocele defects can be closed primarily. Other repair techniques are required for closure of meningomyelocele defects of >5 cm. In this anomaly, in which random or musculocutaneous flaps are usually used, the technique for skin defect closure should have the following criteria: a safely harvested flap with good blood supply; minimal morbidity in the donor site; closure with adequate thickness to protect the underlying neural structure; and a repair to prevent leakage of cerebrospinal fluid. The dorsal intercostal artery perforator flap is a new perforator flap with a large skin island that can be used safely in the dorsal region. In this article, repair of large skin defects due to myelomeningocele has been attempted using a dorsal intercostal artery perforator flap, and the results are discussed.

Effects of lidocaine infiltration on cost of rhinoplasty made under general anesthesia.

This study aimed to compare the effects of combined and noncombined lidocaine with adrenaline infiltration in general anesthesia (GA) procedures, in which the standard anesthesia depth is monitored by Bispectral Index monitoring, on minimum alveolar concentration (MAC) levels and the costs. Following approval by the local ethics committee, an American Society of Anesthesiologists physical status I­II group of 40 adult patients for whom elective rhinoplasties under GA were planned was divided into 2 double-blind randomized groups. In group 1, GA and lidocaine + adrenaline were administered, whereas in group 2, only GA and adrenaline were administered. All the patients who had been taken to the operation room underwent electrocardiography and measurements of the peripheral oxygen saturation, end-tidal carbon dioxide, heart rate, mean blood pressure, and Bispectral Index monitoring. Using the operation time and the MAC% values, the total consumed inhalation agent amounts were calculated, and the cost difference was determined. The mean blood pressure values were lower in group 1 (P < 0.05). In group 1, the MAC% was 20.83% lower than that of group 2; the consumed desflurane amount was 20.29%, and the cost was 20.29% lower than that of group 2 (P < 0.05). In rhinoplasties under GA, the lidocaine + adrenaline combination infiltration not only decreased inhaled anesthetic requirement and cost but also supported the hemodynamic stability. In addition, surgical satisfaction increased in the lidocaine + adrenaline group because of small number of agitated patients during the recovery period.

Use of rotation flap in repair of cleft palate and velopharyngeal insufficiency.

Although cleft palate anomaly is frequent, the criterion standards in surgical treatment have not been determined yet. There are a few techniques described for cleft palate repair owing to the limited tissue in the palatal mucosa, the rigid structure of the palatal mucosa, and the limited vascularity of the hard palate. In this study, a novel cleft palate repair technique based on separating the soft palate from the hard palate as a musculomucosal flap and using it as a rotation flap has been described. The operation is evaluated individually for each anomaly because variations occur in the surgical technique according to the extension of the cleft toward the teeth in the palate. This operation was performed on a total of 28 patients (17 girls and 11 boys) aged between 1.5 and 16 years and presented to our clinic. Patients were assessed for speech analysis outcomes, tympanogram values, hearing functions, magnitude of palatal lengthening during the operation, and rate of fistulae. Statistically significant differences in values of the speech analysis and the audiometric assessment were determined between before and 6 months after surgery. Complete recovery of otitis was observed 1 month after surgery without another treatment in 9 (42.8%) of 21 patients who were detected to have serous otitis media preoperatively. Tension-free closure, lower risk of fistula, good restoration of velopharyngeal functions, ability to be performed on all types of cleft palate, ability to provide a good intraoperative exposure, and being a single stage seem to be the most important advantages of this technique.

Primary repair of the alveolar cleft.

Nasoalveolar fistula and oropharyngeal fistula of the anterior palatal region are very commonly seen in cases when there are concomitant clefts of the lip and the palate. Absence of adequate tissue in that region complicates the treatment and necessitates new tissue transfers from near or distant tissues. Today, the techniques used for correcting cleft lip cannot successfully solve these 2 problems. In this study, we describe a technique that depends on the principle of using the lip mucosal tissues that remains during the Tennison cleft lip correction technique, with a flap designation, to correct the tissue defect of the cleft between the foramen incisivum and lip and the alveolar region. Twenty-two patients (13 boys and 9 girls), with ages ranging from 3 to 53 months (mean, 24 mo), with unilateral cleft lip and palate underwent surgery with this new technique. In all these patients, clefts in the anterior palatal and alveolar regions were successfully corrected. Fistula was observed in none of these patients in these regions. Through this method, clefts in the anterior palatal and alveolar regions can be corrected during repair of cleft lips.

A case report of a patient with cleft palate carrying the risk of tetraplegia.

Spondyloepiphyseal dysplasia congenita (SEDC) is an inherited disorder of bone growth that results in short-trunk dwarfism, skeletal abnormalities, disorders in vision and hearing, atlanto-axial instability, and cleft palate. This important anomaly of the cervical vertebrae carries the risk of tetraplegia during cleft palate operations. In this case report, we discuss a case of spondyloepiphyseal dysplasia congenita, the perioperative and postoperative measures, and the risk of tetraplegia.

[The effects on complications and myopathy of different voltages in electrical injuries]. / Elektrik çarpmalarinda voltaj farkinin komplikasyonlar ve miyopati üzerine etkisi.

BACKGROUND: The purpose of this study was to investigate the demographic and clinical characteristics of electrical injuries, laboratory findings, complications, and mortality and morbidity rates of these injuries. METHODS: Patients with electrical injuries admitted to the emergency department between January 2006-2010 were retrospectively analyzed. The cases were evaluated by age, gender, source of electrical power (low-high voltage), seasonal distribution, ECG changes, laboratory findings, clinical care units, complications, and mortality rate. RESULTS: Eighty-four (57.1%) of the cases were exposed to low-voltage electricity (Group I), while 63 (42.9%) of the cases were exposed to high-voltage electricity (Group II). The majority of cases with electrical injuries were aged 26-45 years. Thirty of the women (85.7%) were wounded by low-voltage while 58 of the men (51.8%) were wounded by high-voltage electricity. Alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, creatine kinase, and CK-MB levels were higher and the level of calcium was lower in Group II. Complications (pathologies due to fall from high levels, cardiac dysrhythmias, compartment syndrome) and the mortality rate were higher in Group II. CONCLUSION: In cases with high-voltage electrical injuries, cardiac complications, complications due to fall from high levels and the mortality rate increase in conjunction with the degree of the muscle damage.

A rare case of fistula: nasocutaneous fistula.

A three-year-old male patient was brought to our clinic by his family with the complaint of a non-healing wound with discharge on his forehead and the nasal region. He had a history of a fall one-year ago. The patient had recurrent complaints of swelling and hyperemia following this trauma. He had undergone an operation with the pre-diagnosis of foreign body in soft tissue six months ago. However, no foreign body had been detected and the inflamed tissue had been excised and closed again. The swelling and purulent discharge in the region between nose and eye continued after this surgery. The patient underwent an operation and a circular defect 0.5 cm in diameter was detected on the dorsum of the nasal bone and a fistula tract was found to have developed between this defect and the skin between the nose and the eye. A subcutaneous forehead flap without skin tissue was removed including the periosteum from the left part of forehead after excision of the fistula tract. The flap was transferred to the nasal dorsum and the component of the forehead flap including the periosteum was used for reconstruction of the nasal mucosa. The wound healed without any problems and no fistula or infection developed again during the six-month follow-up.
