Surgical outcome of modified Karydakis flap and modified Limberg flab in the management of sacroccygeal pilonidal disease: a comparative study

Introduction: Sacrococcygeal pilonidal disease (SPD) is a chronic suppurative condition of the sacrococcygeal region causing chronic sinus tract or cyst. It is an acquired complex disease more common in young adult males, causing considerable morbidity and long periods of interruption in work or education. From simple conservative techniques to complex flap reconstruction, many debatable treatment options are offered; however clear dynamics toward the widespread use of minimally invasive methods and off-midline flap reconstruction are suggested in all guidelines, which recommend the Karydakis and Limberg flap modification. The plethora of literature compares procedures for identification of a single best treatment approach, which has proven to be difficult. The surgical outcome of both techniques is compared in the present study. Objective: To compare the surgical outcomes of the modified Karydakis flap (MKF) versus the modified Limberg flap (MLF) in SPD. Materials and Methods: The present study was conducted at the general surgery department on SPD patients who were ≥18 years old. A total of 67 participants were included after obtaining the informed consent, with group A comprising 33 patients undergoing the MLF procedure and group B comprising 34 patients undergoing the MKF procedure. Results: The mean patient age was 28.85 (range, 18-44) years old. For the MKF and MLF methods, the average operating duration was 32.5 (range, 25-40) and 54.5 (range, 45-65) minutes, respectively. The MKF approach was found to significantly improve pain score, mean sitting painless time, return to normal activity, wound healing time, and patient satisfaction. Conclusion: Comparative outcomes were seen between both MKF and MLF; however, our findings show that MKF is a more favourable method than MLF with superior outcomes. (AU)

Viability of the random pattern dorsal skin flap in mice submitted to photobiomodulation and therapeutic ultrasound / Viabilidade do retalho cutâneo randômico dorsal em camundongos submetidos à fotobiomodulação e ultrassom terapêutico

INTRODUCTION: The skin flap is a surgical technique widely used in clinical practice and generally presents postoperative complications. Therefore, elucidating interventions that assist in tissue conservation is essential. Photobiomodulation (PBM) and therapeutic ultrasound (TUS) are non-invasive alternatives for assisting tissue repair, however, there is no consensus on the parameters used. OBJECTIVE: To describe the effectiveness of the different parameters of PBM and TUS in the viability of the dorsal random pattern skin flap in mice. METHODS: Fifty-five Swiss mice were used, distributed in eleven groups. The animals were submitted to surgical technique including revascularization of the area limited through a plastic barrier (polyester/polyethylene) with the same dimension as the flap. PBM or TUS was applied for five consecutive days. Photographic and thermographic recordings were performed with Cyber-Shot DSC-P72 and FlirC2 cameras and analyzed using the ImageJ® and FLIR Tools software, respectively. In the statistical analysis, the data were submitted to the GraphPad Prism® 8.0 software. Analysis of variance (ANOVA Two-way) and Tukey's post-test was performed, considering 5% significance level. RESULTS: Groups 5 (PBM830 nm; 10 J/cm²) and 6 (TUS 3 MHz; 0.4 W/cm²) showed percentages of viable tissue significantly higher on the third and fifth day of the experiment, when compared to the other groups. The temperature decreased significantly in group 1 when compared to the others in the postoperative period. CONCLUSION: The continuous TUS at 3 MHz and PBM 830 nm were more effective in improving the viability of the dorsal random pattern skin flap in mice.

INTRODUÇÃO: O retalho cutâneo é uma técnica cirúrgica amplamente empregada na prática clínica e comumente apresenta complicações pós-operatórias. Portanto, elucidar intervenções que auxiliem na conservação do tecido são fundamentais. A fotobiomodulação (FBM) e o ultrassom terapêutico (UST) são alternativas não invasivas que auxiliam no reparo tecidual, contudo, ainda não há consenso sobre os parâmetros a serem utilizados. OBJETIVO: Descrever a efetividade dos diferentes parâmetros da FBM e do UST na viabilidade do retalho cutâneo randômico dorsal em camundongos. MÉTODOS: Utilizou-se 55 camundongos Swiss, distribuídos em onze grupos. Os animais foram submetidos à técnica cirúrgica com a revascularização da área limitada através de uma barreira plástica (poliéster/polietileno) da mesma dimensão do retalho. Aplicou-se a FBM ou UST durante cinco dias consecutivos. O registro fotográfico e termográfico foi realizado com as câmeras Cyber-Shot DSC-P72 e FlirC2, sendo posteriormente analisados nos softwares ImageJ® e FLIR Tools, respectivamente. Na análise estatística, os dados foram submetidos ao software GraphPad Prism® 8.0 e ao teste Shapiro-Wilk para a análise da normalidade. Realizou-se a análise de variância (ANOVA Two-way) e pós-teste de Tukey, com nível de significância de 5%. RESULTADOS: Os grupos 5 (FBM 830 nm; 10 J/cm²) e 6 (UST 3 MHz; 0,4W/cm²) apresentaram porcentagens de tecido viável significativamente maiores no terceiro e quinto dia do experimento. A temperatura reduziu significativamente no grupo-1 quando comparado aos demais no pós-operatório. CONCLUSÃO: O UST contínuo a 3 MHz e FBM 830 nm, foram mais eficazes melhorando a viabilidade a do retalho cutâneo randômico dorsal em camundongos.

Reanimação estática do lábio inferior na paralisia facial como complicação de preenchimento / Static lower lip reanimation as a filler complication of facial paralysis

Procedimentos de rejuvenescimento facial substitutos da cirurgia tradicional tornaram-se cada vez mais populares para promover uma aparência jovial com procedimentos minimamente invasivos, como toxina botulínica injetável, preenchimento de tecidos moles e peelings químicos. No entanto, complicações podem ocorrer mesmo na presença de um injetor habilidoso e experiente. Apresentamos o caso de uma paciente submetida a reanimação labial estática usando retalho dermoadiposo para lesão do nervo facial direito após remoção de nódulos como complicação de preenchimento. A "abordagem modificada de bull horn" foi realizada para elevação do lábio superior em torno das asas nasais e columela e ao longo do sulco nasolabial direito. O retalho foi desepitelizado e obtido. Usando a ponta aberta de uma pequena cânula de lipoaspiração, a porção distal do retalho foi encapsulada e fixada diretamente em C-loop e foram utilizados pontos U, transfixando o retalho para o periósteo do arco zigomático. Nos três anos de seguimento não foram observadas complicações significativas e a paciente não relatou nenhuma limitação funcional ou insatisfação com o aspecto das cicatrizes no sulco nasolabial e ao redor das asas nasais e da columela.

Facial rejuvenation procedures to circumvent traditional surgery have become increasingly popular to promote a youthful appearance with minimally invasive procedures such as injectable botulinum toxin, soft-tissue fillers, and chemical peels. Nevertheless, complications can occur even with an astute and experienced injector. Here we present the case of a patient who underwent static lip reanimation using a dermoadiposal flap for right facial nerve damage following nodule removal as a filler complication. A "modified bulls horn approach" to the upper lip lift was performed around the nasal wings and columella and along the right nasolabial fold. The flap was de-epithelized and harvested. Using the open tip of a small liposuction cannula, the distal portion of the flap was tunneled and fixed directly in a C-loop fashion using U stitches, transfixing the flap to the periosteum of the zygomatic arch. At 3 years follow-up, no significant complications were observed, and the patient reported no functional limitations or dissatisfaction with the scars in the nasolabial fold or around the nasal wings and columella.

Tratamento para queloides: revisão de literatura / Treatment of keloids: a literature review

Introdução: Queloides surgem de resposta excessiva à lesão da derme, resultando em proliferação de fibroblastos, produção exagerada de colágeno e comprometimento da pele sadia adjacente. O diagnóstico é clínico e muitos métodos conservadores e cirúrgicos já foram utilizados para tratamento. Porém, dados da eficácia desses tratamentos são limitados e não há consenso na literatura quanto a melhor técnica a ser empregada, permanecendo uma lacuna que necessita ser preenchida, a fim de que seus usos sejam indicados com maior confiabilidade, em um modelo de medicina baseada em evidências. Métodos: Revisão não sistemática da literatura sobre "queloides" nas bases de dados PubMed, Scielo, MEDLINE, UptoDate e livros-texto das áreas de Dermatologia e Cirurgia Dermatológica. Revisão de Literatura: Foram enumeradas e abordadas as principais informações sobre técnicas cirúrgicas e adjuvantes empregadas para essas lesões, que são: excisão, injeções intralesionais, crioterapia, laserterapia, revestimento com gel de silicone, radioterapia e pressoterapia. Torna-se relevante o levantamento dessas informações, tendo em vista que, além de poder causar dor, prurido e restrição de movimento, o principal motivo da procura de assistência médica para queloide é devido ao aspecto cosmético/estético, e as taxas de reincidência e falha terapêutica ainda são altas, sendo necessário conscientizar o paciente sobre o procedimento e seus efeitos. Conclusão: São muitos os tratamentos disponíveis para o queloide, sejam cirúrgicos ou não, todavia não há consenso sobre uma abordagem universalmente aceita. São necessários mais estudos, com a finalidade de definir a melhor conduta e atingir melhores resultados, visto a qualidade mediana das evidências apresentadas nos estudos.

Introduction: Keloids are characterized by an abnormal response to dermal trauma, resulting in fibroblast proliferation, excessive collagen production, and impairment of adjacent healthy tissue. The diagnosis is clinical, and many conservative and surgical methods can be used as treatments. However, data on the efficacy of these treatments are limited, and there is no consensus regarding the best treatment option. This gap needs to be filled by developing comprehensive evidence-based therapies. Methods: A non-systematic literature review of keloid scars was carried out using PubMed, Scielo, MEDLINE, UptoDate, and dermatology and dermatological surgery textbooks. Literature review: The search retrieved relevant information on surgical and adjuvant therapies used for keloids, including excision, intralesional injections, cryotherapy, laser therapy, silicone gel sheeting, radiation therapy, and pressure therapy. These data are crucial because, in addition to complaints of pain, itching, and restriction of movement, the main reason for seeking treatment for keloids is for cosmetic and aesthetic improvement, and the rates of recurrence and treatment failure are high, emphasizing the importance of creating awareness regarding the available procedures and their effectiveness. Conclusion: Many surgical and adjuvant therapies for keloids are available. Nonetheless, there is no consensus on a universally accepted treatment. Therefore, additional high-quality studies are needed to identify the most effective therapeutic approaches to achieve better results.

Comparación entre suturas convencional coadyuvada con ulmoplus® y sin ulmoplus® en el cierre de incisiones de piel de conejo ( Oryctolagus cuniculus ) / Comparison between conventional sutures with ulmoplus® and without ulmoplus® in the incision closure of rabbit skin ( Oryctolagus cuniculus )

Considerando los avances en las investigaciones que relacionan los efectos terapéuticos de la miel en el proceso de cicatrización de heridas, la presente investigación tuvo como objetivo evaluar y comparar cualitativamente, a través de una análisis morfológico, la respuesta tisular local entre sutura convencional coadyuvada con Ulmoplus® y sin Ulmoplus® en el cierre de la incisión de piel de conejo. Se utilizaron 10 conejos adultos, divididos en grupo S (sutura) y grupo S+U (sutura más Ulmoplus®). Se les realizó una incisión de 10 mm de largo, en la región anterior de la pierna, a través de la epidermis y dermis, hasta llegar a la fascia profunda que cubría al músculo tibial anterior. Posteriormente, solo al grupo S+U se le aplicó Ulmoplus®. Luego, en ambos grupos, la incisión fue suturada con dos puntos intradérmicos de ácido poliglicólico (vicryl 2/0). Después de 10 días post incisión fueron tomadas las biopsias de la piel y procesadas para su observación en microscopio de luz. El estudio se llevó a cabo considerando las recomendaciones de la Guía para el Cuidado y Uso de Animales de Laboratorio. Ambos grupos presentaron una incisión cerrada al día 10, con características microscópicas propias de una fase proliferativa. No obstante, el grupo S+U mostró una cicatriz de menor longitud y de aspecto más plano, cuya epidermis estaba mejor organizada y era de menor grosor, con células basales diferenciadas. A nivel dérmico se observó contracción de la herida, evidenciándose una zona cicatrizal de menor tamaño. Ulmoplus®, es una buena alternativa como coadyuvante en el proceso de cierre de heridas quirúrgicas utilizando sutura convencional, ya que acelera el proceso de cicatrización y permite mejores resultados estéticos de la cicatriz.

Considering the advances in research that relate honey therapeutic effects in wound healing process, the present investigation aimed to evaluate and compare qualitatively, through morphological analysis, the local tissue response between conventional suture with Ulmoplus ® and without Ulmoplus ® in the closure of the rabbit skin incision. We used 10 adult rabbits, divided into group S (suture) and group S + U (suture plus Ulmoplus®). An 10 mm long incision was made in the anterior region of the leg, passing through epidermis and dermis, until reaching the deep fascia that covered the anterior tibial muscle. Subsequently, only the S + U group was given Ulmoplus®. Then, in both groups, the incision was sutured with two intradermal points of polyglycolic acid (vicryl 2/0). After 10 days post incision, biopsies of the skin were taken and processed for observation in a light microscope. The study was carried out considering the recommendations of the Guide for the Care and Use of Laboratory Animals. Both groups had a closed incision at day 10 with microscopic characteristics of a proliferative phase. However, the S + U group showed a scar of shorter length and flatter appearance, whose epidermis was more organized and thinner, with differentiated basal cells. At the dermal level, wound contraction was observed, evidencing a smaller scar area. Ulmoplus®, as a coadjuvant in closing surgical wounds process using conventional suture is a good alternative, since it accelerates the healing process and allows better aesthetic results of the scar.

Seguridad, eficacia y tolerabilidad de un novedoso apósito de gel de silicona para uso posoperatorio en cirugía dermatológica / Safety, efficacy and tolerability of a novel silicone gel dressing for postoperative use in dermatological surgery

Durante muchos años, el gel de silicona ha tenido un rol primario en el tratamiento y la prevención de cicatrices anómalas en forma de cicatrices hipertróficas y queloides luego de la epitelización. Los autores publican los hallazgos preliminares sobre el uso de un novedoso apósito de gel de silicona grado médico que forma una película y que fue aprobado para ser usado en heridas abiertas y en lesiones de la piel como único tratamiento y en combinación con otros tratamientos previos a la reepitelización. Un estudio observacional de 105 pacientes analizó la efectividad del gel de silicona en la estimulación de la epitelización acelerada, la reducción de la respuesta inflamatoria y la prevención de la formación de cicatrices. El estudio se realizó en una variedad de intervenciones quirúrgicas dermatológicas. Las observaciones de los autores confirmaron el rol de la silicona en la aceleración de la cicatrización de heridas, la prevención de la formación de cicatrices y la utilidad de este nuevo apósito de silicona que forma una película cuando se lo combina con otras modalidades de tratamiento. (SKINmed. 2012; 10:S1- S7).

The authors publish the pre-elimination findings use of a novel medical grade silicone gel dressing that form a film that was approved for use in open wounds and in skin as the only treatment and in combination with other treatments prior to re-epithelialization. An observational study of 105 patients analyzed the effectiveness of silicone gel in the stimulation of accelerated epithelialization, reducing the inflammatory response and preventing the formation of scars. The study was conducted on a variety of dermatological surgeries. The authors' observations confirmed the role of silicone in acceleration of wound healing, prevention of the formation of the usefulness of this new silicone dressing that forms a film it is combined with other forms of treatment.

Clinical Analysis of Serial (Staged) Excision for Congenital Melanocytic Nevi: A Single-center Experience / 대한피부과학회지

BACKGROUND: Serial (staged) excision of congenital melanocytic nevi (CMN) is an important treatment option for medium-sized CMN. However, few studies have investigated the outcomes of serial excision in detail.OBJECTIVE: We report our experience regarding serial excision of CMN, including methods to effectively reduce the procedural stages and scar length.METHODS: We retrospectively reviewed medical records of patients with CMN treated between 2008 and 2015; 33 patients (7 men and 26 women) underwent serial excision.RESULTS: The CMN were located on the face (n=11), arms (n=6), legs (n=11), and other areas of the body (n=11), including the back (n=2), chest (n=1), deltoid region (n=1), and buttocks (n=1). The mean CMN area was 19.7 cm². The mean number of surgical stages was 2.2. The mean interval between surgeries was 10.6 months. A marginal S-shaped incision along both edges of the nevus was preferred over elliptical excision, to reduce scarring. Pulsed dye, erbium:yttrium–aluminum–garnet (YAG), neodymium-doped:YAG, and carbon dioxide fractional lasers were used to improve the final outcomes and minimize scarring.CONCLUSION: Serial excision is an effective treatment option associated with greater patient satisfaction, particularly for medium-sized and hairy CMN. Conventional elliptical serial excision is associated with the formation of elongated scars and sacrifices normal skin adjacent to the lesion. The marginal S-shaped incision reduces scarring by dispersing mechanical tension on the scar without skin wastage. Compared with the elliptical excision method, the marginal S-shaped incision reduces the number of surgical stages and results in a cosmetically superior scar. Performing a marginal S-shaped incision is technically challenging in certain anatomical locations, such as the eyes, nose, and mouth. Therefore, it is necessary to combine this procedure with erbium:YAG and neodymium-doped:YAG ablation.

Effect of short-term ischemia on microcirculation and wound healing of adipocutaneous flaps in the rat

Abstract Purpose Composite flaps used in reconstructive surgery may intra- and postoperatively suffer from hypoperfusion and/or ischemia-reperfusion influencing wound healing. We aimed to follow-up the effect of ischemia on adipocutaneous flaps' wound healing and microcirculation. Methods In anesthetized rats groin flaps were formed bilaterally. In Control group the flaps were repositioned and sutured back. In Ischemia-Reperfusion (I/R) group before repositioning and suturing the flap pedicles were clamped for 60 minutes. Laser Doppler (LD) fluxmetry and temperature probes were applied on the cranial, central and caudal flap regions before/after preparation and ischemia, re-suturing, and on the 1st-3rd-5th-7th-14th postoperative days, before the final examinations and biopsies for histology. Results Flaps' skin temperature quickly recovered after repositioning. LD values were lower in the I/R group, reaching a significant level by the 3rd postoperative day, and remained lowered till the 14th day. The magnitude of alterations differed in the flap regions. Histologically normal wound healing process was seen, except for some I/R flaps, where hypertrophized mammary glands were found. Conclusions Short-term ischemia could influence flap microcirculation and wound healing, and may result in hypertrophized mammary glands. Laser Doppler could be used to evaluate intra- and postoperative microcirculatory changes and may have significance in predicting complications.

Electrocirugía en procedimientos dermatológicos en pacientes portadores de dispositivos eléctricos cardíacos implantables / Electrosurgery in dermatological procedures in patients with implantable cardiac electrical devices

Debido al acelerado envejecimiento de la población, cada vez es mayor la cantidad de usuarios portado-res de dispositivos electrónicos cardíacos implan-tables (DECI). Muchos de estos pacientes se verán enfrentados a procedimientos dermatológicos que con frecuencia utilizan equipos de electrocirugía. Es-tos tienen riesgo potencial de producir interferencias electromagnéticas (IEM), y por lo tanto alterar el fun-cionamiento de estos dispositivos. Si bien no todos los DECI tienen las mismas características, las nuevas tec-nologías de estos dispositivos han disminuido, aunque no eliminado completamente, el riesgo de IEM. Este artículo tiene como propósito revisar el tema y recopilar las recomendaciones generales que todo dermatólogo debe conocer tanto en la fase preoperatoria, intraoperatoria, como postoperatoria al utilizar equipos de electrocirugía en un paciente con DECI.

Due to the accelerated population aging, an increa-sing number of users is carrying cardiac implantable electronic devices (CIEDs). Many of these patients will face dermatological procedures that often use electrosurgical equipment. The latter has the poten-tial to produce electromagnetic interference (EMI), and therefore alter the operation of these devices. While not all CIEDs have the same characteristics, new technologies for these devices have decreased if not eliminated completely the risk of EMI.The purpose of this article is to review CIED topic and compile general recommendations that every dermatologist should be aware of, both in the preoperative, intraoperative, and postoperative phases when using electrosurgery equipment in a patient with CIED.

Outcomes of external septorhinoplasty in a Turkish male population / Resultados de rinosseptoplastia externa em uma população turca do sexo masculino

Abstract Introduction The first and one of the most important steps in facial plastic surgery is accurate preoperative facial analysis and recording of data that may help the surgeon to check the outcomes of his/her techniques, promoting a surgeon's professional development. Objective To evaluate the esthetic outcomes of external septorhinoplasty relevant to ethnic facial harmony and to investigate the relationship of the columellar incision scar with the type of skin and columellar incision type in a Turkish population. Methods In total, 28 consecutive adult male patients with a mean age of 32.14 ± 10.66 years (range: 18-61 years) were included the study. Primary outcomes were preoperative and postoperative photogrammetric facial analyses of the patients including measurement of nasofrontal angle, nasolabial angle and nasal projection ratios (Gode) assessed according to the data derived from the Rhinobase program. Results were compared to facial proportions of the Turkish population. Columellar incision scar scores related to the Fitzpatrick skin type classification of the patients and columellar incision types used for the external approach were secondary outcomes of the study. Results Mean preoperative and postoperative nasofrontal angles were 148.04° ± 8.18° and 144.50° ± 7.15°, respectively, while mean preoperative and postoperative nasolabial angles were 87.59° ± 14.01° and 98.50° ± 9.71°, respectively. Mean preoperative and postoperative nasal tip projection ratios were 0.56 ± 0.05 and 0.60 ± 0.06, respectively. The differences between pre- and postoperative measurements were all significantly different and were in accordance with Turkish nasal harmony. Columellar inverted "V" incisions were performed in 15 (53.6%) patients while "V" incisions were used in 13 (46.4%) patients. Fitzpatrick skin Type 4 was seen in 46.42% of the patients, Fitzpatrick Type 3 in 46.42% and Fitzpatrick Type 2 in 7.14% of the patients. No significant difference was seen between columellar scar scores according to skin type and columellar incision type used for external septorhinoplasty. Conclusions This study demonstrated that outcomes for nasofrontal angle, nasolabial angle and nasal tip projection ratios analyzed using the Rhinobase program in patients who underwent external septorhinoplasty were similar to reference values for the Turkish population.

Resumo Introdução O primeiro e um dos mais importantes passos na cirurgia plástica facial é a análise pré-operatória facial precisa e o registro de dados que podem ajudar o cirurgião a verificar os resultados de suas técnicas, promovendo seu desenvolvimento profissional. Objetivo Avaliar os resultados estéticos da rinosseptoplastia externa relevantes para a harmonia étnica facial e investigar a associação da cicatriz de incisão columelar com o tipo de pele e o tipo de incisão columelar em uma população turca. Método No total, 28 pacientes adultos consecutivos com média de idade de 32,14 ± 10,66 anos (intervalo: 18-61 anos) foram incluídos no estudo. Os desfechos primários foram as análises faciais fotogramétricas pré-operatórias e pós-operatórias dos pacientes, incluindo a medida do ângulo nasofrontal, ângulo nasolabial e razões da projeção nasal (Gode), avaliados de acordo com os dados derivados do programa Rhinobase. Os resultados foram comparados às proporções faciais da população turca. Os escores de cicatriz de incisão columelar relacionados com a classificação de Fitzpatrick do tipo de pele dos pacientes e os tipos de incisão columelar usados para a abordagem externa foram os desfechos secundários do estudo. Resultados Os ângulos nasofrontais pré- e pós-operatórios médios foram 148,04 ± 8,18° e 144,50 ± 7,15°, respectivamente, enquanto os ângulos nasolabiais pré- e pós-operatórios médios foram 87,59 ± 14,01° e 98,50 ± 9,71°, respectivamente. As razões médias da projeção nasal pré- e pós-operatória foram de 0,56 ± 0,05 e 0,60 ± 0,06, respectivamente. As diferenças entre as medidas pré- e pós-operatórias foram todas significativamente diferentes e estavam de acordo com a harmonia nasal turca. A incisão columelar em "V" invertido foi utilizada em 15 (53,6%) pacientes e a incisão em "V" foi utilizada em 13 (46,4%) pacientes. Pele Fitzpatrick tipo 4 foi observada em 46,42% dos pacientes, Fitzpatrick tipo 3 em 46,42% e Fitzpatrick tipo 2 em 7,14% dos pacientes. Não foi observada diferença significativa entre os escores de cicatriz columelar de acordo com o tipo de pele e o tipo de incisão columelar utilizados na rinosseptoplastia externa. Conclusões Este estudo demonstrou que os desfechos para ângulo nasofrontal, ângulo nasolabial e razões de projeção nasal analisados pelo programa Rhinobase em pacientes submetidos à rinosseptoplastia externa foram semelhantes aos valores de referência para a população turca.

Effectiveness of double tie-over dressing compared with bolster dressing

BACKGROUND: Skin grafting is a commonly performed operation in plastic and reconstructive surgery. The tie-over dressing is an effective technique to secure the grafted skin by delivering persistent downward pressure. However, if an additional dressing is required due to incomplete graft healing, the process of re-implementing the tie-over dressing may be frustrating for both patients and surgeons. Therefore, we introduce the double tie-over dressing, which readily allows for an additional tie-over dressing after the first dressing, and we present a comparison of its effectiveness with that of the simpler bolster dressing. METHODS: Of 128 patients with a skin defect, 69 received a double tie-over dressing and 59 patients received a simple bolster dressing. Using the independent t-test, the mean healing time, which was defined as the mean time it took for the wound to heal completely so that no additional dressing was required and it was washable with tap water, was compared between the 2 groups in both the head and neck region and in other areas. RESULTS: The mean healing time for the head and neck region in the double tie-over dressing group was 9.19±1.78 days, while it was 11.05±3.85 days in the bolster dressing group. The comparison of the 2 groups by the independent t-test revealed a P-value of 0.003 for the mean healing time. CONCLUSIONS: In the head and neck area, the double tie-over dressing required less time to heal than the simple bolster dressing.

Giant congenital melanocytic nevi: 40 years of experience with the serial excision technique

Abstract: Although giant congenital melanocytic nevus is a rare lesion, it causes significant deformity and carries a risk of malignant degeneration. Different surgical techniques for the lesion removal are described, including serial resection, resection with skin grafting, and resection and coverage with expanded skin flap (skin expanders). The aim of this study is to report the author's 40 years of experience with cases requiring at least 4 serial excisions to complete the treatment. Serial resection is an effective, safe, and simple technique that requires a lot of patience. Treatment often results in a single linear scar, requires no donor sites, nor large flaps. It is not subject to potencial complications of expanders and avoid aesthetic deformities depending on the location.
