An age-unknown, 4.8 kg, male, wild, domestic short-hair cat was presented for left hindlimb lameness. A physical examination revealed a draining tract which was suspected of bite on left calcaneal bone. The left tarsal joint was markedly swollen and exudates were observed around the draining tract. Sequestrum at left calcaneus bone, and osteolysis were identified by radiography. The sequestrum and its surrounding exudative tissue were debrided during surgery and the tissue was submitted for bacterial culture and sensitivity test. The debridement caused a bone defect ($1.5cm{\times}0.5cm{\times}0.5cm$) on the medial left calcaneal bone. Plate and screw fixation was performed to the calcaneus bone as buttress plate. Recombinant human bone morphogenetic protein-2 (rhBMP-2) loaded hydroxyapatite was implanted in the bone defect. Furthermore, Amikacin-impregnated collagen sponges were also placed around bone plate to deliver local antibiotics. A systemic antibiotic treatment regimen based on bacterial culture and sensitivity test results was administered for 4 weeks. The wound properly healed without any signs of infection, and the bone healing was confirmed by radiography. The patient showed normal weight bearing ambulation at 18 weeks after surgery. The use of rhBMP-2 and local antibiotic delivery system is a good surgical option for the one-stage treatment of chronic osteomyelitis.
Objective : Our aim is to evaluate the early changes of biologic markers such as white blood cell[WBC] count, erythrocyte sedimentation rate[ESR] and C-reactive protein[CRP] in early diagnosis of postoperative infection and to differentiate infection from inflammatory reaction in lumbar spine surgery. Methods : We reviewed 330patients who had undergone spinal operations between May 1999 and October 2001. For this study, the patients were classified into two groups, which include a group that underwent spinal decompressive surgery without instrumentation[SD], and the other group that underwent fusion surgery with spinal instrumentation[SI]. And each group was also subdivided into two groups respectively, one with infection and the other without infection. We retrospectively analyzed the WBC count, ESR and CRP preoperatively and postoperatively, according to their operation type and postoperative infection history. Results : Inflammatory indices were physiologically affected by instrumentation itself. But ESR and CRP elevations were more prolonged and sustained under infection. In SD patients without infection, ESR and CRP were stabilized 5 days after surgery. In SI patients without infection, CRP was stabilized about 7days after surgery, but ESR showed sustained and variously elevated. In both SD and SI groups, the stabilization of CRP was the most reliable behavior of surgery without infection. Conclusion : C-reactive protein is most sensitive parameter for postoperative spine infection. The knowledge of the inflammatory indices and their relatively uniform patterns with or without infection offers surgeons the ability to infer the state of surgical wound.
Lateral eyebrow mass with primary skull lesion are rare in pediatric population. Although epidermoid cyst and dermoid cyst are the most commonly encountered skull lesions in pediatric population, Langerhans cell histiocytosis (LCH) is rarely reported. We report a case of LCH arising from the lateral eyebrow with osteolytic lesion involving the frontal bone. A 5-year-old boy was presented with a hard, fixed mass in his lateral eyebrow. Contrast magnetic resonance imaging revealed inhomogeneous enhancement of the mass with direct invasion of the frontal bone and adjacent dura mater. Under general anesthesia, linear incision at the lateral eyebrow region was made. Intraoperative evaluation revealed hard, fixed and well-defined soft tissue mass. The final extirpated mass was $2.5{\times}2.4cm$ in size, and was accompanied by a $1{\times}1cm$ sized defect on the frontal bone with intact dura mater. The surgical wound was closed primarily by a layer-by-layer fashion. Histologic examination was later performed for definite diagnosis. The histologic examination revealed abnormal proliferation of Langerhans cell with granuloma formation. Radionuclide bone scan and positron emission tomography was taken and revealed free of multi-organ involvement. At 3 months after surgery, natural looking contour at the lateral eyebrow region was observed with no tumor recurrence. Differential diagnosis of the hard and fixed mass at the lateral eyebrow region affecting the primary skull lesion from pediatric population includes epidermoid cyst, dermoid cyst and LCH. Generally, brief physical examination with plain X-ray view can be performed for clinical evaluation, but for a definite diagnosis, contrast MRI may be helpful.
The diagnosis of the main complications resulting from lipoabdominoplasty has not yet been standardized. Infrared thermal imaging has been used to assess possible complications, such as necrosis and changes in micro- and macro-circulation, based on perforator mapping techniques, among others. The objective of this study was to present two clinical cases involving thermal imaging monitoring of the healing process of lipoabdominoplasty in the immediate postoperative evaluation and its preliminary results. Infrared thermography was performed 24 hours after the operation and on postoperative days 5, 25, and 27. In clinical case 1, it was found that the delta-R (∆TR)-defined as the difference in minimum temperature between the highest and lowest points in the SA3 region (caution suction area) following the classification established by Matarasso-was 0.4℃ at 24 hours after surgery and decreased to 0.1℃ on a postoperative day 5. There were no complications in this case. In contrast, in clinical case 2, the ∆TR was 1.7℃ at 24 hours after surgery (upon hospital discharge) and remained high, at 2.2℃, on postoperative day 5. A higher ∆TR was found in the second patient, who developed necrosis of the surgical wound. The ∆TR thermal index may be a new tool for predicting possible complications, complementing the clinical evaluation and therapeutic decision-making.

Our faces can express a remarkable range of subtle emotions and silent messages. Because the face is so essential for complex social interactions that are part of our everyday lives, aesthetic repair and restoration of function are an important tasks that we must not take lightly. Soft-tissue defects occur in trauma patients and require thorough evaluation, planning, and surgical treatment to achieve optimal functional and aesthetic outcomes, while minimizing the risk of complications. Recognizing the full nature of the injury and developing a logical treatment plan help determine whether there will be future aesthetic or functional deformities. Proper classification of the wound enables appropriate treatment, and helps predict the postoperative appearance and function. Comprehensive care of trauma patients requires a diverse breadth of skills, beginning with an initial evaluation, followed by resuscitation. Traditionally, facial defects have been managed with closure or grafting, and prosthetic obturators. Sometimes, however, large defects cannot be closed using simple methods. Such cases, which involve exposure of critical structures, bone, joint spaces, and neurovascular structures, requires more complex treatment. We reviewed and classified causes of significant trauma resulting in facial injuries that were reconstructed by microsurgical techniques without simple sutures or coverage with partial flaps. A local flap is a good choice for reconstruction, but large defects are hard to cover with a local flap alone. Early microsurgical reconstruction of a large facial defect is an excellent choice for aesthetic and functional outcomes.
Author planed peroneal artery perforator flap for ankle reconstruction and experienced successful result using sural neuro-lesser saphenous venous flap due to an unexpected event. A male Asian patient, 24 years old, had a history of recurrent operation wound disruption in the ankle region. Under general anesthesia, peroneal perforator and saphenous vein, as well as the sural nerve branches, were identified and preserved. In the process of flap rotation, an accidental division of peroneal artery perforator has occurred. Despite the division of the perforator, circulation was normal. The patient experienced no complication after the surgery. Some study reported that accompanying arteries and the vascular plexus around the sural nerve communicate. In conclusion, sufficient blood supply was possible only with the accompanying artery of the sural nerve without peroneal perforator. So, it is essential to always preserve not only perforator but also neurovascular bundles at any circumstances and any location.
Background The endoscopic transnasal approach is widely used for reconstructing the medial orbital wall by filling it with a silicone sheet or Merocel, but this technique has the disadvantage of retaining the packing for a long time. To overcome this drawback, a method of positioning an absorbable plate in the orbit has been introduced, but there is a risk of defect recurrence after the plate is absorbed. Here, the authors report the results of a novel surgical technique of placing a nonabsorbable titanium mesh with porous polyethylene into the orbit through the endoscopic transnasal approach. Methods Fourteen patients underwent surgery using the endoscopic transnasal approach. Preoperative computed tomography (CT) was used to calculate the size of the bone defect due to the fracture, and the titanium mesh was designed to be shorter than the anteroposterior length of the defect and longer than its height. The titanium mesh was inserted into the orbit under an endoscopic view. The authors then confirmed that the titanium mesh supported the orbital contents by pressing the eyeball and finished the operation. Immediately after surgery, CT results were evaluated. Results Postoperative CT scans confirmed that the titanium mesh was well-inserted and in the correct position. All patients were discharged without any complications. Conclusions We obtained satisfactory results by inserting a titanium mesh with porous polyethylene into the orbit via the transnasal approach endoscopically.

Background: Cryptotia is a congenital anomaly in which the upper part of the retroauricular sulcus is absent and buried underneath the temporal skin. Various surgical techniques have been reported for the correction of cryptotia following Kubo's V-Y plasty in 1933. Conventional methods using a local skin flap, skin grafting, tissue expansion, Z-plasty, and any of these combined approaches can result in skin deficiency of the upper auricle. The aim of this study was to develop a new method that improves cosmetic results and has fewer complications. Methods: This study involved four patients in whom five cryptotia deformities were corrected using V-Y plasty and Z-plasty. After elevation of the flap, acellular dermal matrix (ADM; MegaDerm) that was over 5 mm in thickness was applied to the cephalo-auricular angle and positioned to enhance the projection of the ear. Lastly, the flap was transposed to complete the repair. Results: Between January 2014 and February 2018, cryptotia correction with ADM graft was performed in four patients. None of the patients developed a recurrence of cryptotia, and there were no postoperative complications such as wound infection, seroma formation, and dehiscence. In addition, the procedures resulted in a favorable cosmetic appearance. Conclusion: Based on these findings, i.e., no recurrence and a favorable cosmetic result, when using an ADM graft, it is suggested that this technique could be an alternative method of cryptotia correction. It could also lessen donor-site morbidity when compared to autologous cartilage grafting and be more cost-effective than using cartilage from a cadaver.
Background: To compare the outcomes of video-assisted thoracoscopic surgery (VATS) in comparison to open thoracic surgery in pediatric patients suffering from empyema. Methods: A prospective study was carried out in 80 patients referred to the Department of Pediatric Surgery between 2015 and 2018. The patients were randomly divided into thoracotomy and VATS groups (groups I and II, respectively). Forty patients were in the thoracotomy group (16 males [40%], 24 females [60%]; average age, $5.77{\pm}4.08years$) and 40 patients were in the VATS group (18 males [45%], 22 females [55%]; average age, $6.27{\pm}3.67years$). There were no significant differences in age (p=0.61) or sex (p=0.26). Routine preliminary workups for all patients were ordered, and the patients were followed up for 90 days at regular intervals. Results: The average length of hospital stay ($16.28{\pm}7.83days$ vs. $15.83{\pm}9.44days$, p=0.04) and the duration of treatment needed for pain relief (10 days vs. 5 days, p=0.004) were longer in the thoracotomy group than in the VATS group. Thoracotomy patients had surgical wound infections in 27.3% of cases, whereas no cases of infection were reported in the VATS group (p=0.04). Conclusion: Our results indicate that VATS was not only less invasive than thoracotomy, but also showed promising results, such as an earlier discharge from the hospital and fewer postoperative complications.
Reconstruction of defects around the knee region requires thin and pliable skin. The superior lateral genicular artery (SLGA) flap provides an excellent alternative to muscle-based flaps. The anatomy and the surgical techniques of the SLGA flap were reviewed and the results of cases using the SLGA flap for coverage of knee and proximal leg defects were analyzed. SLGA flaps were performed in two cases and followed up for at least 6 months. Twelve articles on the use of the SLGA flap were also identified. A review of 39 cases showed that the mean diameter of the perforator supplying the skin of the flap was 1.04 mm, while the mean diameter of the SLGA at its origin was 1.78 mm. The mean length of the pedicle measured from the origin of the popliteal artery was 7.44 cm. The average dimensions of the flap were 14.8×6.6 cm with primary closure of the donor site in 61.5% of cases. Of these cases, 38.5% were due to trauma, 23.1% were post-burn complications, 12.8% were defects after resection of tumors, and 10.3% were for ulcers post-bursectomy. The most common complication was flap tip necrosis. All studies reported favorable outcomes with complete wound healing.
