Objective : The purpose of this study was to evaluate the efficacy of the anterior approach following intraoperative reduction under general anesthesia in patients with cervical facet fracture and dislocation. Methods : Twenty-three patients with single level cervical facet fracture and dislocation who were subjected to the anterior approach alone following immediate intraoperative reduction under general anesthesia from March 2013 to December 2017 were enrolled in this study. Neurological status, clinical outcome, and radiological studies were evaluated preoperatively, postoperatively, and during the follow-up period. Results : The cohort comprised 15 men and eight women with a mean age of 57 years (from 24 to 81). All patients were operated on within the first 8 hours following the injury. After gentle manual reduction or closed reduction with Gardner-Wells traction, under general anesthesia monitored by somatosensory-evoked potentials, all operations were successfully completed using the anterior approach alone except in two patients, who had a risk of over-distraction. In them, a satisfactory gentle manual reduction or closed reduction was not possible, and required open posterior reduction of the locked facets followed by anterior cervical discectomy and fusion. In one patient, screw retropulsion was observed in 1 month after surgery. There were no reduction-related complications or neurological aggravations after surgery. All patients showed evidence of stability at the instrumented level at the final follow-up (mean follow-up, 12 months). Conclusion : Anterior approach following intraoperative reduction monitored by somatosensory-evoked potentials under general anesthesia for cervical dislocation and locked facets is a relatively safe and effective alternative when cervical alignment is achieved by intraoperative reduction.

Objective: This systematic review aimed to provide a comparative analysis of the treatment outcomes, including hard and soft tissues, postoperative stability, temporomandibular disorders (TMD), and quality of life (QoL), in patients with facial asymmetry who underwent orthognathic surgery. Methods: The primary objective was to address the question, "How do different factors related to surgery affect the outcomes and stability of orthognathic surgery in the correction of facial asymmetry?" A meta-analysis was conducted on the outcome parameters, such as skeletal, dental, and soft tissue symmetry, TMD, QoL, and relapse, using the Hartung-Knapp-Sidik-Jonkman method for random-effects models. Subgroup analyses were conducted considering surgery-related factors such as surgical techniques (one-jaw vs. two-jaw), use of the surgery-first approach, utilization of computer simulation, and analytical methods employed to evaluate asymmetry (2D vs. 3D). Results: Forty-nine articles met the inclusion criteria. The metaanalysis demonstrated a significant improvement in the symmetry of hard and soft tissues. The subgroup analysis indicated that the treatment outcomes showed significant improvement, regardless of the factors related to surgery. Changes in TMD signs and symptoms varied according to the surgical technique used. Quality of life improved in the facial, oral, and social domains. Skeletal relapse was observed during the follow-up. Conclusions: Our findings support the positive outcomes of orthognathic surgery in the treatment of facial asymmetry in terms of skeletal and soft tissue improvements, stability, relief of TMD symptoms, and enhancement of QoL. However, most of the included studies showed a low certainty of evidence and high heterogeneity.

Backgrounds/Aims: No reports to compare incisional hernia (IH) incidence between laparoscopic and open colorectal liver metastases (CRLM) resections have previously been made. This is the first comparative study. Methods: Single-center retrospective review of patients who underwent CRLM surgery between January 2011 and December 2018. IH relating to liver surgery was confirmed by computed tomography. Patients were divided into laparoscopic liver resection (LLR) and open liver resection (OLR) groups. Data collection included age, sex, presence of diabetes mellitus, steroid intake, history of previous hernia or liver resection, subcutaneous and peri-renal fat thickness, preoperative creatinine and albumin, American Society of Anesthesiologists (ASA) score, major liver resection, surgical site infection, synchronous presentation, and preoperative chemotherapy. Results: Two hundred and forty-seven patients were included with a mean follow-up period of 41 ± 29 months (mean ± standard deviation). Eighty seven (35%) patients had LLR and 160 patients had OLR. No significant difference in the incidence of IH between LLR and OLR was found at 1 and 3 years, respectively ([10%, 19%] vs. [10%, 19%], p = 0.95). On multivariate analysis, previous hernia history (hazard ratio [HR], 2.22; 95% confidence interval [CI], 1.56-4.86) and subcutaneous fat thickness (HR, 2.22; 95% CI, 1.19-4.13) were independent risk factors. Length of hospital stay was shorter in LLR (6 ± 4 days vs. 10 ± 8 days, p < 0.001), in comparison to OLR. Conclusions: In CRLM, no difference in the incidence of IH between LLR and OLR was found. Previous hernia and subcutaneous fat thickness were risk factors. Further studies are needed to assess modifiable risk factors to develop IH in LLR.

Objective : Pituitary apoplexy is one of the most serious life-threatening complications of pituitary adenoma. The purpose of this study is to investigate the visual outcome after early transsphenoidal surgery for the patients with pituitary apoplexy. Methods : We retrospectively reviewed the 31 patients with pituitary apoplexy who were admitted due to acute visual acuity or field impairment and treated by transsphenoidal surgery. Five patients were excluded because of the decreased conscious level. The visual acuity of each individual eye was evaluated by Snellen's chart Visual fields were also checked using automated perimetry. To compare the visual outcome according to the surgical timing, we divided the patients into 2 groups. The first group, 21 of the patients have been undertaken transsphenoidal approach (TSA) within at least 48 hours after admission. The second group included 8 patients who have been undertaken TSA beyond 48 hours. All patients were monitored at least 12 months after surgery. Results : Patients were 21 males and 8 females (M : F=2.6 : 1) with the mean age of 42.4 years. Among the enrolled 29 patients, 26 patients presented with decreased visual acuity and 23 patients revealed the defective visual field respectively. Postoperatively, improvement in the visual acuity was seen in 15 patients (83.3%) who underwent surgery within the first 48 hours of presentation, as compared to those in whom surgery was delayed beyond 48 hours (n=5; 62.5%) (p=0.014). Improvement in the visual field deficits was observed in 15 (88.2%) of patients who had been operated on within the first 48 hours of presentation, as compared to those in whom surgery was delayed beyond 48 hours (n=3; 50.0%) (p=0.037). Conclusion : This study suggests that rapid transsphenoidal surgery is effective to recover the visual impairment in patients with pituitary apoplexy. If there are associated abnormalities of visual acuity or visual fields in patients with hemorrhagic pituitary apoplexy, early neurosurgical intervention within 48 hours should be also required to recover visual impairment.

Background Giant congenital melanocytic nevus (GCMN) is a rare disease, for which complete surgical resection is recommended. However, the size of the lesions presents problems for the management of the condition. The most popular approach is to use a tissue expander; however, single-stage expansion in reconstructive surgery for GCMN cannot always address the entire defect. Few reports have compared tissue expansion techniques. The present study compared single and serial expansion to analyze the risk factors for complications and the surgical outcomes of the two techniques. Methods We retrospectively reviewed the medical charts of patients who underwent tissue expander reconstruction between March 2011 and July 2019. Serial expansion was indicated in cases of anatomically obvious defects after the first expansion, limited skin expansion with two more expander insertions, or capsular contracture after removal of the first expander. Results Fifty-five patients (88 cases) were analyzed, of whom 31 underwent serial expansion. The number of expanders inserted was higher in the serial-expansion group (P<0.001). The back and lower extremities were the most common locations for single and serial expansion, respectively (P =0.043). Multivariate analysis showed that sex (odds ratio [OR], 0.257; P=0.015), expander size (OR, 1.016; P=0.015), and inflation volume (OR, 0.987; P=0.015) were risk factors for complications. Conclusions Serial expansion is a good option for GCMN management. We demonstrated that large-sized expanders and large inflation volumes can lead to complications, and therefore require risk-reducing strategies. Nonetheless, serial expansion with proper management is appropriate for certain patients and can provide aesthetically satisfactory outcomes.

Spontaneous extensor pollicis longus tendon rupture is commonly caused by attrition of the tendon from trauma or inflammatory processes. We experienced a patient with extensor pollicis longus tendon rupture after steroid injection, in which the rupture may have been caused by the effects of steroid itself as well as direct damage from the needle. A 51-year-old woman complained of inability to extend her right thumb at the first metacarpophalangal & interphalangeal joint level. The patient had a history of local steroid injection into the dorsal & radial side of wrist on two occations, and had no history of trauma or rheumatologic disease. After a physical examination of the patient, we decided to explore the wrist. The patient agreed with operation. Intraoperatively, an incision was made into the wrist and the proximal and distal ends of the ruptured extensor pollicis longus tendon were identified. The defect between the proximal and the distal end was measured to approach 8cm, and a palmaris longus tendon graft was performed. After three months of rehabilitation, the first metacarpophalangal & interphalangeal joint recovered the normal range of motion. Steroid injection has been widely used in various musculoskeletal disorders such as rheumatoid arthritis and osteoarthritis. However, inadvertent steroid injection into the extra or intra articular spaces may lead to tendon rupture. Steroids reduce tensile strength by decreasing tenocyte activity and collagen synthesis. Also, the physical effect of direct needle-stick injury into the mesotenon and blood vessels around the tendon may cause damage. In addition, hematoma and edema may increase pressure around the tendon and compromise blood supply, leading to tendon degeneration and subsequent rupture. When injecting steroid into an articular area, all physicians should have a complete understanding of the surrounding anatomy and always keep in mind the hazards of such procedures.

Purpose: Eczema herpeticum, caused by herpes simplex virus, is an infectious disease involving skin and internal organs. Varieties of physiologic, psychosocial, or environmental stress reactivate reservoir virus which exists in the trigeminal nerve ganglia. Authors report rare cases of nasal eczema herpeticum following corrective rhinoplasty. Methods: First case, 22-year-old female underwent corrective rhioplasty through an external approach in a local clinic. She developed progressive and painful erythema, nodules and vesicles on nose on the 9th day postoperatively. This unfamiliar lesion lead to a misdiagnosis as a bacterial infection, and had accelerated its progress to the trigeminal innervation of the nasal unit. Second case, a 23-year-old female underwent corrective rhinoplasty by external lateral osteotomy. Ten days after the surgery, disruption occurred on the external osteotomy site, and the ulceration gradually worsened. The surgeon misdiagnosed it as secondary bacterial infection and only an antibacterial agent was applied. Results: Both cases were healed effectively without any complication with proper wound dressing and antiviral therapy, and show no sequelae during an 8-month follow-up period. Conclusion: Eczema herpeticum is rare in the field of plastic surgery, but it should be kept in mind that secondary bacterial infections may lead to serious complications such as full-thickness skin loss. Thus, acknowledgement of the patient's past history regarding perioral or intraoral lesion may provide the surgeon with the possible expectancy of eczema herpeticum. Thus, if anyone develops eczema herpeticum, following facial plastic surgery, early diagnosis and immediate proper antiviral therapy will allow fast recovery without serious complications.

Background The aim of unilateral breast reconstruction after mastectomy is to craft a natural-looking breast with symmetry. The latissimus dorsi (LD) flap with implant is an established technique for this purpose. However, it is challenging to obtain adequate volume and satisfactory aesthetic results using a one-stage operation when considering factors such as muscle atrophy, wound dehiscence and excessive scarring. The two-stage reconstruction addresses these difficulties by using a tissue expander to gradually enlarge the skin pocket which eventually holds an appropriately sized implant. Methods We analyzed nine patients who underwent unilateral two-stage LD reconstruction. In the first stage, an expander was placed along with the LD flap to reconstruct the mastectomy defect, followed by gradual tissue expansion to achieve overexpansion of the skin pocket. The final implant volume was determined by measuring the residual expander volume after aspirating the excess saline. Finally, the expander was replaced with the chosen implant. Results The average volume of tissue expansion was 460 mL. The resultant expansion allowed an implant ranging in volume from 255 to 420 mL to be placed alongside the LD muscle. Seven patients scored less than six on the relative breast retraction assessment formula for breast symmetry, indicating excellent breast symmetry. The remaining two patients scored between six and eight, indicating good symmetry. Conclusions This approach allows the size of the eventual implant to be estimated after the skin pocket has healed completely and the LD muscle has undergone natural atrophy. Optimal reconstruction results were achieved using this approach.

Background: Clefts in newborns are associated with severe morphological and functional impairment. Especially the lip is of importance as if the treatment result is unsatisfactory, it can lead to psychological changes in the patient. Different operative procedures have been developed over the last decades. The aim of the presented study was the comparison of the surgical techniques according to Millard and Pfeifer regarding the temporal development of the postoperative symmetry of the lip height and mouth width. Methods: Digitized photographs of patients from the department of oral and maxillofacial surgery at the University of Göttingen were evaluated from 1979 to 1996. With a video analysis program, the lip height and mouth width were analyzed regarding the symmetry. We demonstrated the symmetry values over a period of 8 years in order to show the influence of growth on postoperative results. Results: The development of the vertical symmetry of the Philtrum and the lip vermillion on the cleft side in comparison to the healthy side behaves differently depending on Pfeifer and Millard. The lip height of the cleft lip was shorter in both techniques than on the healthy side, but Pfeifer's difference was significantly more pronounced. The lip vermillion height on the cleft side was slightly shorter in the Millard group and markedly larger in the Pfeifer group. Both techniques can achieve good symmetry results for the vertical dimension of the lip. According to Pfeifer, the development of the horizontal dimension on the cleft side is bigger within the first 4 years than on the healthy side; according to the Millard technique, the horizontal development is smaller. These differences are greater within the first 6 years and approach between the 6th and 8th year. Conclusions: The Millard technique demonstrates better results concerning the philtrum and vermillion symmetry during growth within the first 6 years. Over the whole study period, growth corrects the philtrum and vermillion symmetry within the Pfeifer group.

Sternal malunion, or loss, developed after a median sternotomy cannot only be difficult to manage and treat, but also may diminish one's quality-of-life drastically. The technique presented here represents a multispecialty approach in one stage for the reconstruction of an unstable thoracic cage. The procedure utilized a donated sternum and ribs. The sternum with ribs harvested from a single donor included adipose derived stromal vascular fraction (ADSVF) cells with marrow also from the same donor. Autologous muscle flaps, stabilized with acellular dermal matrix were utilized to provide a robust blood supply to the ADSVF cells and bone grafts. Acellular dermal matrix was used to construct the ribs and stabilize the plugs of stem cells and bone. These procedures, in the hands of multispecialty physicians, have led to several successful reconstructions involving complex chest wall deformities. This surgical intervention was performed in a one stage operation. This represents the first successful complete sternal transplant in a patient with return to normal activities and increased quality-of-life.
