PURPOSE: To describe an unusual case of pediatric iris melanocytoma with pigment dispersion glaucoma that resolved after resection of the primary tumor. METHODS: Retrospective case review of the clinical record, ultrasonographic images, and histopathology. RESULTS: A 6-year-old Asian girl, with a dark iris tumor, pigment dispersion, and secondary glaucoma, was initially treated with topical antiglaucoma medication and observation. Rapid growth prompted biopsy, revealing melanocytoma. As the tumor continued to grow, excision of the primary tumor was performed. Surgery proved curative in that the pigment dispersion slowly reabsorbed and her glaucoma resolved. CONCLUSIONS: In this case, rapid growth did not indicate malignant transformation. Initial observation for growth and judiciously timed surgical intervention prevented progression, loss of vision, and potentially the loss of the eye.

Computer assisted modeling (CAM) has become an important tool in surgical oncology and reconstructive surgery. The preservation of the limb is an important consideration when approaching the treatment of lower extremity and pelvic tumors. The use of cutting guides allows for optimal conservation of disease-free bone and maintenance of function. We present a small case series that illustrates the use of CAM in patients with lower extremity and pelvic bone tumors.

OBJECTIVE: To report on the prevalence of voice disturbances in the pediatric craniofacial population and to prove that the pediatric Voice Handicap Index (pVHI) is a useful questionnaire for this unique population. STUDY DESIGN: Case series with chart review. SETTING: Tertiary care center. SUBJECTS: Pediatric patients seen by a pediatric otolaryngologist in a craniofacial clinic. METHODS: Consecutive patients (N = 366) seen by a single pediatric otolaryngologist in a craniofacial clinic from July 2011 to September 2012 were included. Any patient specifically referred for airway problems or voice difficulties completed a pVHI questionnaire. Patients each underwent an evaluation including flexible fiberoptic laryngoscopy and videostroboscopy. Voice disturbance was further characterized into dysphonia, hypernasality, or hyponasality. RESULTS: Of all the patients evaluated, 280 (77%) were specifically referred for airway problems or voice disturbance. Of those referred, 39 (10.7%) were found to have an organic vocal fold pathology causing dysphonia, as seen on the videostroboscopic examination; 53.7% of these lesions were attributable to potential iatrogenic causes. Hypernasality and hyponasality were seen in 116 (31.7%) and 78 (21.3%) patients, respectively. The pVHI was 3.95, 26.3, 11.34, and 10.53 for those with no voice disturbance, dysphonia, hypernasality, and hyponasality, respectively. CONCLUSION: Pediatric patients with craniofacial disorders have a higher prevalence of dysphonia than the general pediatric population. The majority of causes of dysphonia in these patients are possibly iatrogenic in origin. The pVHI serves as a useful questionnaire in this unique patient cohort to quantify the disability from not only dysphonia but also hypernasality and hyponasality.

The subspecialty of craniofacial surgery emphasizes skeletal exposure, preservation of critical structures, and provision of a superior cosmetic result. In recent decades, an emphasis on minimally invasive neurosurgical exposure has paved the way for increased collaboration between neurosurgeons and craniofacial surgeons.The 1990s saw the growing popularity of an eyebrow incision for orbital roof craniotomies in neurosurgery to address lesions in the anterior skull base. Disadvantages of this approach included conspicuous scarring above the brow skin, risk of injury to the frontal branch of the facial nerve, and numbness from supraorbital or supratrochlear nerve transection.A transpalpebral approach was first described in 2008 in the neurosurgical literature. An approach familiar to the craniofacial surgeon, transpalpebral exposure is used for zygomaticomaxillary complex fractures as well as aesthetic brow and periorbital surgery.In conjunction with neurosurgery, the authors have applied craniofacial principles to address the major pitfalls of the transpalpebral craniotomy. The authors present their patient series experience. Hopefully, in the future, other institutions will have increased collaboration between craniofacial surgeons and neurosurgeons.

PURPOSE: To compare the bone bonding capabilities of 2 different surface treatments at an early healing period. Titanium alloy (Ti6Al4V) custom-made rectangular plates (1.4 x 2.4 x 4 mm) were either dual acid etched (Ti6Al4V-DAE) or DAE/nanotextured blasted (Ti6Al4V-NTB). MATERIALS AND METHODS: Implants were placed in the distal femurs of 10 Wistar rats and were allowed to heal for 9 days. After euthanasia, the bone immediately proximal and distal to the implant was removed to test the bone bonding force with a universal testing machine. Ultrastructure of the bone/implant interface was assessed by scanning electron microscopy. RESULTS: Ti6Al4V-NTB samples exhibited significantly greater bond strength than Ti6Al4V-DAE samples. Morphologically, the Ti6Al4V-NTB surfaces presented intimate interaction with bone, whereas little interaction between the Ti6Al4V-DAE surface and bone was observed. CONCLUSION: The results of this study indicated a significant increase in bone bonding for the DAE/nanotextured blasted surface, which is suggested to be the outcome of the nanotexturing.

BACKGROUND: Refinements in microsurgical breast reconstruction have refined superficial inferior epigastric artery (SIEA) and superficial circumflex iliac artery (SCIA) flaps, yet technical difficulties and varied success rates limit widespread acceptance. The authors present the outcomes of their experience with 145 consecutive SIEA/SCIA flaps and suggest technical tips to improve success with this important flap. METHODS: An institutional review board-approved retrospective chart review of all SIEA/SCIA free flaps performed by the senior authors between January 1, 2006, and February 6, 2014, was conducted. Data on patient demographics, flap characteristics, and complications were collected. RESULTS: There were 145 flaps performed in 119 patients. Arterial donor and recipient mismatch occurred in 55 instances (38 percent). In these cases, 48 arteries (87 percent) were spatulated and seven (13 percent) were back-cut to improve size concordance. Nine flaps required operative return for flap viability concerns. Five were arterial, three were venous, and one flap had concomitant arterial and venous thrombosis. Total flap loss rate attributable to thrombotic events was 4.8 percent. No flaps with arterial thrombosis on reoperation were salvageable. Furthermore, 80 percent had arterial revisions at initial operation. No patients had an abdominal bulge or hernia, and the fat necrosis rate was 10.3 percent. CONCLUSIONS: SIEA/SCIA breast reconstruction can be reliably performed; however, flaps exhibiting postoperative arterial thrombosis with revision at initial surgery are unlikely salvageable on reoperation. Spatulation did not correlate with an increased thrombosis rate; in fact, the authors advocate for donor artery manipulation to manage size mismatch.

OBJECTIVE: There exist inherent problems with previously described classification schemes for head and neck lymphatic malformations in children and lack of guidance for management. An organization scheme and management recommendations are proposed to improve communication between health care providers. STUDY DESIGN: Consecutive patient series with a chart review of children with head and neck lymphatic malformations. SETTING: Tertiary-care, academic children's hospital. METHODS: Children with lymphatic malformations of the head and neck were included. A proposed organization system for head and neck lymphatic malformations in children was developed and compared to 2 others currently predominantly used, de Serres and Cologne Disease Score. RESULTS: Seventeen patients were identified, 7 boys and 10 girls. The mean age was 64.4 months (range 0.89-185.5). Nine patients (52.9%) were managed expectantly, 5 (29.4%) with sclerotherapy with 1 awaiting treatment (5.9%), and 2 (11.8%) with surgical excision. All children who underwent active treatment with surgery or sclerotherapy were managed successfully. No treatment-related complications were encountered, and no children managed with watchful waiting/expectant management experienced failure. The proposed staging system differed from the de Serres stage in 11 children (64.7%), with 9 (81.8%) being down staged and 2 (18.2%) up staged. Cologne Disease Score ranged from 2 to 10, with only 1 (5.9%) patient with a score of 3 or less (severe disease). CONCLUSIONS: Treatment recommendations in children with head and neck lymphatic malformations should be individualized. Weaknesses of currently used staging systems are discussed as well as considerations for management decisions.

Clinical face transplantation, only 10 years old, has evolved into a safe and preferred reconstructive option for the most severe facial defects, in which traditional reconstructive methods have yielded poor outcomes. The ability to simultaneously restore facial function and aesthetics has shown to improve patient's quality of life. Its applicability to post-oncologic resection, however, remains guarded given the current international experience with respect to long term outcomes. J. Surg. Oncol.

BACKGROUND: The aim of this study was to perform an updated systematic review of the literature over the last 10 years, analyzing and comparing the many published techniques with the hope of providing plastic surgeons with a new standard in creating the perfect umbilicus in the setting of both abdominoplasty and abdominally based free-flap breast reconstruction. METHODS: An initial search using the PubMed online database with the keyword "umbilicoplasty" was performed. These results were filtered to only include articles published within the last 10 years. The remaining articles were thoroughly reviewed by the authors and only those pertaining to techniques for umbilicoplasty in the setting of abdominoplasty and abdominally based free flap were included. RESULTS: Of the 10 unique techniques yielded by our search, 9/10 (90 %) initially incised the native umbilicus with a round, oval, or vertical ellipse pattern. Of the 9 techniques that initially perform a round incision, 4 of them (44.4 %) later modify the round umbilicus with either an inferior or superior excision to create either a "U"- or "inverted U"-shaped umbilicus. In terms of the shape of the incision made in the abdominal flap for umbilical reinsertion, the most common were either a round incision or an inverted "V" or "U," both of which accounted for 4/10 (40 %) and 3/10 (30 %), respectively. Almost all of the studies (8/10; 80 %) describe "defatting" or trimming of the subcutaneous adipose tissue around the incision to create a periumbilical concavity following inset of the umbilicus. 4/10 (40 %) of the techniques describe suturing the dermis of the umbilical skin to rectus fascia. Furthermore, 3/10 (30 %) advise that stalk plication is a necessary step to their technique. 7/9 techniques (77.8 %) preferred nondissolvable sutures for skin closure, with nylon being the most common suture material used. Only 2/9 (22.2 %) used dissolvable sutures. CONCLUSION: Although future studies are necessary, it is our hope that this systematic review better elucidates the techniques and provides some guidance to both aesthetic and reconstructive plastic surgeons in the pursuit of creating the perfect umbilicus following abdominoplasty and TRAM/DIEP breast reconstruction.
