Efficacy of passive helmet therapy for deformational plagiocephaly: report of 1050 cases.

OBJECT: There has been a tremendous increase in the incidence of deformational plagiocephaly in children throughout the world. Therapeutic options include observation, active counterpositioning, external orthotics, and surgery. The current treatment in the US is highly debated, but it typically includes external orthotic helmets in patients with moderate to severe plagiocephaly presenting between 4 and 10 months of age or in children with significant comorbidities limiting passive (no-pressure) therapy. The present study was designed to evaluate 3 key issues: 1) the accuracy of the Argenta classification in defining a progressive degree of severity, 2) identification of an upper age limit when treatment is no longer effective, and 3) the effectiveness of an off-the-shelf prefabricated helmet in correcting deformational plagiocephaly. METHODS: An institutional review board-approved retrospective study was conducted of all patients at the authors' clinic in whom deformational plagiocephaly was assessed using the Argenta classification system over a 6-year period; the patients underwent helmet therapy, and a minimum of 3 clinic visits were recorded. Inclusion criteria consisted of an Argenta Type II-V plagiocephalic deformity. Patients' conditions were categorized both by severity of the deformity and by patients' age at presentation. Statistical analysis was conducted using survival analysis. RESULTS: There were 1050 patients included in the study. Patients with Type III, IV, and V plagiocephaly required progressively longer for deformity correction to be achieved than patients with Type II plagiocephaly (53%, 75%, and 81% longer, respectively [p < 0.0001]). This finding verified that the Argenta stratification indicated a progressive severity of deformity. No statistically significant difference in the time to correction was noted among the different age categories, which suggests that the previously held upper time limit for correction may be inaccurate. An overall correction rate to Type I plagiocephaly of 81.6% was achieved irrespective of severity and degree of the original deformity. This suggests that an inexpensive off-the-shelf molding helmet is highly effective and that expensive custom-fitted orthoses may not be necessary. The patients in the older age group (> 12 months) did not have a statistically significant longer interval to correction than the patients in the youngest age group (< 3 months). The mean length of follow-up was 6.3 months. CONCLUSIONS: Patients treated with passive helmet therapy in the older age group (> 12 months) had an improvement in skull shape within the same treatment interval as the patients in the younger age group (< 3 months). This study supports the use of passive helmet therapy for improvement in deformational plagiocephaly in infants from birth to 18 months of age and verifies the stratification of degree of deformity used in the Argenta classification system.

Minimizing donor-site morbidity following bilateral pedicled TRAM breast reconstruction with the double mesh fold over technique.

INTRODUCTION: Transverse rectus abdominus muscle flaps (TRAM) can result in significant abdominal wall donor-site morbidity. We present our experience with bilateral pedicle TRAM breast reconstruction using a double-layered polypropylene mesh fold over technique to repair the rectus fascia. METHODS: A retrospective study was performed that included patients with bilateral pedicle TRAM breast reconstruction and abdominal reconstruction using a double-layered polypropylene mesh fold over technique. RESULTS: Thirty-five patients met the study criteria with a mean age of 49 years old and mean follow-up of 7.4 years. There were no instances of abdominal hernia and only 2 cases (5.7%) of abdominal bulge. Other abdominal complications included partial umbilical necrosis (14.3%), seroma (11.4%), partial wound dehiscence (8.6%), abdominal weakness (5.7%), abdominal laxity (2.9%), and hematoma (2.9%). CONCLUSIONS: The TRAM flap is a reliable option for bilateral autologous breast reconstruction. Using the double mesh repair of the abdominal wall can reduce instances of an abdominal bulge and hernia.

Congenital pyriform aperture stenosis.

Neonates rely on the nasal airway for their source of air; thus, any compromise in the ability to inhale will dramatically alter their ability to breathe. Congenital nasal pyriform aperture stenosis is a rare yet serious form of airway obstruction due to overgrowth of the maxilla at the medial nasal process. Infants typically present with difficulty feeding and obvious difficulty breathing. Radiologic imaging aids in confirming the diagnosis and assists in operative planning to open the medial nasal process to reduce airway resistance. Further corrective surgery is often needed and is planned commensurate with facial growth. We present a novel case of a child diagnosed with congenital nasal pyriform aperture stenosis who has performed extraordinarily well intellectually and has achieved an excellent cosmetic and physiological reconstruction of the nose and airway.

Difficulties of delayed treatment of craniosynostosis in a patient with Crouzon, increased intracranial pressure, and papilledema.

Crouzon syndrome is an autosomal dominant disorder characterized by cranial synostosis, hypertelorism, orbital proptosis, parrot-beaked nose, short upper lip, hypoplastic maxilla, and a relative mandibular prognathism, without extremity involvement. Surgical intervention should occur at the onset of progressive craniosynostosis to treat or to prevent intracranial hypertension and visual impairment. Throughout developing countries, early treatment is often not a viable option. Often, the only option for treatment is through humanitarian missions. Appropriate preselection of surgical patients is essential, as is having a multidisciplinary team and a well-equipped hospital and staff to perform the operations and to care for the postsurgical patient. This type of humanitarian care benefits the patient selected to receive the intense logistical and financial effort when there is no possibility of timely care in their own countries. This clinical report describes a patient with Crouzon syndrome brought to the United States from a developing country through humanitarian efforts. She presented at 19 months of age with bicoronal and sagittal synostosis and advanced visual impairment and papilledema. Surgical intervention included cranial expansion and reconstruction with a multidisciplinary team. This case illustrates not only the difficulty of delayed treatment but also some of the issues arising from this type of humanitarian medical care.

Giant facial lymphangioma.

Lymphatic malformation (LM) is a benign cystic entity resulting from aberrant lymphatic drainage. Often evident at birth, most LMs have declared themselves by 2 years of age. They can be concerning when they occur near vital structures such as the airway or orbit. The natural history varies considerable from spontaneous gradual regression to long-term growth and debilitation. Depending on the location, structures involved, and clinical course of the LM, therapeutic options include observation, intralesional sclerosis, laser therapy, and surgical excision. The literature provides guidelines for treatment options that must be carefully applied to the facial region. We present a newborn infant who presented to our institution with giant facial lymphangioma who underwent a combination of sclerosis, laser ablation, and surgery with reconstruction.

Aplasia cutis congenita: clinical management of a rare congenital anomaly.

BACKGROUND: Aplasia cutis congenita (ACC) is a rare congenital disorder characterized by absence of skin and adjacent tissue that usually affects the scalp, but any part of the body may be affected. Although ACC is more often superficial and small, it can be large and involve the underlying structures such as skull and dura, thus increasing the risk of hemorrhage, infection, and mortality. Controversy exists regarding nonsurgical versus surgical intervention for this condition. This study reviews indications and modalities for treatment of this rare congenital anomaly. RESULTS: Management of this anomaly depends on size, location, and structures at risk. Small lesions with intact underlying structures and lesions affecting extremities are treated in a conservative fashion with dressings and ointments followed by delayed scar excision. Aplasia cutis congenita scar excision often requires complex tissue rearrangement, tissue expansion, or skin grafting. Larger ACC lesions or lesions with exposure of vital structures require early surgical intervention. Initially, exposed vital structures and bony ridges can be protected using conservative measures. Delayed definitive repair can then be performed using scalp flaps, split- and full-thickness skin grafts, cultured epithelial autografts, delayed split rib cranioplasty, tissue expansion, and composite cranioplasty. CONCLUSIONS: Aplasia cutis congenita should be individually evaluated based on size, depth, location, and tissues involved. Using conservative and surgical modalities, one can achieve complete closure of the defect, thus avoiding risks of infection, hemorrhage, and further trauma.

Spring-assisted surgery-a surgeon's manual for the manufacture and utilization of springs in craniofacial surgery.

BACKGROUND AND PURPOSE: Spring-assisted surgery has been used for the treatment of craniofacial deformities since its 1997 inception in Sweden by Dr Lauritzen (Scand J Plast Reconstr Surg Hand Surg 1998;32:331-338). Initial applications have focused on the treatment of patients with single-suture craniosynostosis. Recently, indications and applications have expanded to include patients with syndromic craniosynostosis, multiple-suture synostosis, and midface hypoplasia. The advancement of spring-assisted surgery in this country has been hindered by the need for patient-specific spring fabrication because few surgeons understand how to make the springs for each application. We will review our spring design and treatment algorithms to facilitate wider use of this innovative treatment modality. METHODS: This is a retrospective institutional review board-approved analysis of the spring design for our first 90 cases of spring-assisted surgery used to treat sagittal synostosis at the North Carolina Center for Cleft and Craniofacial Deformities. Outcome analysis was done to generate a treatment algorithm based on diagnosis, patient age, spring design, number of springs, spring force and expansion, and clinical outcome. RESULTS: Ninety children with sagittal craniosynostosis (64 males, 26 females) were treated during an 8-year period (2001-2009) with spring-assisted surgery. Mean age at treatment was 4.4 months and mean age at spring removal was 8.8 months. Mean number of springs used was 2 (range, 1-3). Mean spring force used in sagittal synostosis was 5.5-9.5 (range) for the anterior spring and 5.5-9.5 (range) for the posterior spring with a mean posttreatment expansion of 6.65 cm. Analysis of the results shows that spring force and expansion required for optimal correction is dependent on the age at surgery, type of the deformity, and severity of the deformity. Specifically, the younger the child, the weaker the spring needed for surgical correction. General principles for spring application for scaphocephaly include (1) the longer the anterior posterior dimension of the skull deformity, the more likely a third spring is necessary; (2) the narrower the posterior occiput, the stronger the posterior spring required; and (3) if a postcoronal band is seen in the calvarium, a stronger anterior spring is needed. CONCLUSIONS: Long-term experience with spring-assisted surgery has facilitated the development of standardized, reproducible techniques allowing spring design modifications to optimize clinical outcome.

Surgical treatment for scaphocephaly and a calcified cephalohematoma.

Craniosynostosis is the premature fusion of 1 or more of the cranial sutures, with sagittal synostosis being the most common nonsyndromic single suture synostosis. The pathogenesis of craniosynostosis has been extensively studied and is likely multi-factorial. A complex interaction between the dura and overlying suture via multiple growth factors seems to play the most important role. There have been 3 published studies with patients presenting with scaphocephaly and a cephalohematoma, which raises the question of how the 2 conditions may be related. Cephalohematomas can be seen after trauma and a number of other causative factors but usually resorb over time without sequela. In a small percentage of cases, the hematoma persists and calcifies, leading to significant asymmetry and deformity of the skull. Once it reaches this point, surgical intervention may be required to correct the resulting skull deformity. We present a child with scaphocephaly and a cephalohematoma who underwent surgical correction with resection of the cephalohematoma and sagittal suturectomy with spring-assisted surgery.

Proboscis lateralis: a rare craniofacial anomaly, reconstruction, and long-term evaluation.

Proboscis lateralis is a rare spontaneous congenital anomaly that results from a failure of normal embryological nasal development. The ensuing deformity consists of imbrication of the nasal soft tissues into a tubelike proboscis and can be associated with ipsilateral heminasal aplasia, choanal atresia, and multiple other abnormalities. A case report of a patient with proboscis lateralis is presented, with a 27-year follow-up detailing the complexities of long-term surgical management. After 15 major surgical interventions, there is relatively normal facial symmetry, but abnormalities remain with the underlying craniofacial skeleton and nasopharyngeal airway. Proboscis lateralis is not an isolated soft tissue abnormality but is a craniofacial defect that requires a long-term multidisciplinary approach to the surgical timing and treatment with lifelong follow-up.

Latest trends in minimally invasive synostosis surgery: a review.

PURPOSE OF REVIEW: To present the current surgical options for minimally invasive surgery for treatment of craniosynostosis. RECENT FINDINGS: Minimally invasive procedures are well tolerated treatment options for patients with craniosynostosis. Suturectomy and helmet therapy is a treatment option for scaphocephaly with minimal blood loss and length of hospital stay. Spring-mediated cranioplasty is, in addition, a well tolerated and effective treatment option for scaphocephaly. SUMMARY: In patients with multiple suture craniosynostosis, surgical techniques that utilize spring-assisted surgery can provide decreased morbidity with better bone formation made available for a second operation. Continued basic science research and clinical studies will expand the use and provide further minimally invasive procedures to infants with craniosynostosis.

Spring-assisted cranioplasty vs pi-plasty for sagittal synostosis--a long term follow-up study.

Spring-assisted cranioplasty (SAS) has been used for the treatment of selected cases of sagittal synostosis at our unit routinely since 1998. In order to assess the long-term outcomes of this procedure, we compared the clinical data and morbidity with the pi-plasty technique, our previous standard procedure for the treatment of such children. The first 20 consecutive patients who underwent SAS for isolated sagittal synostosis with complete records, and who were 3 years old at the time of this study, were included. Twenty patients with a pi-plasty performed in the period immediately preceding the spring group acted as a control group. Cephalograms (preoperative, 1-year and 3-year), clinical examination, medical record data, medical photography, and a questionnaire (spring-group only) were used to evaluate and compare these two groups. The mean age of the spring group was 3.5 months (2.5-5.5) and the pi-plasty group 7.1 months (4-15.5) of age at surgery. There were no deaths in either group. There was a higher rate of complications in the pi-plasty group. The skull morphology was similar preoperatively in both groups but slightly different at the 3-year follow-up. The mean cephalic index (CI) in the spring group was 72 at 1 year of age and 71 at 3 years of age, indicating a minor relapse. The pi-plasty group had a mean CI of 73 at 3 years of age. The length was the same in both groups however the pi-plasty group had a lower height (mean 2 mm) and wider biparietal distance (mean 5 mm). All parents of the spring group were highly satisfied with the aesthetic results achieved, would undergo the operation again, and would recommend it to others with scaphocephaly. It was concluded that the two groups of surgery resulted in a quite similar morphologic outcome. The pi-plasty group had a cephalic index marginally closer to the normal range at 3 years of age. The spring group was superior with respect to blood loss, transfusion requirements, operative time, ICU time, recovery time, and total hospital stay.

The evolving role of springs in craniofacial surgery: the first 100 clinical cases.

BACKGROUND: The use of springs in craniofacial surgery originated at Sahlgrenska University Hospital in 1997 as a way of remodeling the cranial vault postoperatively. METHODS: The hospital records of the first 100 operations involving spring placement were analyzed retrospectively. Demographic, perioperative, and postoperative data were recorded. RESULTS: Two hundred forty-six springs were used in 96 patients. Results for sagittal, metopic, bicoronal, multiple synostoses, and midface surgery are presented. In total, five patients (5 percent) required further surgery because of undercorrection. There were no major complications. Spring dislodgement (5 percent) was the most common complication in early cases. Raised intracranial pressure resulted in a protocol change with the use of compressive springs. The data compare favorably with those of standard craniofacial procedures performed in the same unit. CONCLUSIONS: This therapeutic modality in craniofacial surgery has allowed minimization of the extent of surgery without compromising clinical outcomes. Springs have now become part of the authors' treatment protocol for craniosynostosis and midface surgery. The authors have shown the use of these techniques to be safe and, in selected situations, to offer significant advantages over other methods of treatment.

Dynamic spring mediated cranioplasty in an experimental model with resorbable foot plates.

Craniofacial surgery continues to be progressive in its approach to maximize function and aesthetic appearance while minimizing risks and complications. Dynamic springs are one way to minimize invasiveness while achieving favorable results. The purpose of this study was to show the safety and efficacy of dynamic springs with resorbable foot plates for treatment of metopic suture abnormalities in a swine model. The study population consisted of twelve 20 kg Chester swine. The swine were divided into two treatment groups: four in the sham surgery group and eight in the stainless steel spring group. Postoperative analysis consisted of evaluation of the skull growth over time and integrity of the foot plates and underlying dura. The swine, killed at 8 weeks, were examined for spring location in the foot plates, ease of removal of the spring, and postmortem histologic analysis of the bone growth. No morbidity or mortality occurred in the immediate perioperative period secondary to the surgery. Postmortem histologic analysis revealed no infections or complications related to the surgery. Statistical analysis using a mixed linear model with an unstructured variance-covariance matrix was fit. In conclusion, this study confirms the efficacy and safety of the spring-mediated cranioplasty at the metopic suture with use of resorbable foot plates in a swine model.

Maximizing results in craniofacial surgery with bioresorbable fixation devices.

The resorbable plating system allows the infant's skull to grow once the system is resorbed, thus not inhibiting the necessary developmental growth seen with the titanium system. Despite marked improvements in long-term outcomes, there are still technical points that can be followed to maximize outcome while reducing and possibly eliminating minor complications such as plate palpability and visibility through the skin as well as skin breakdown over the plate. A retrospective electronic chart review was performed on the pediatric patient population who underwent craniofacial surgery with the use of resorbable fixation devices by the senior author (LG). Fifty-two patients underwent surgical correction for craniosynostosis with resorbable material (Craniosorb, Lactosorb, or Biosorb PDX). This series included patients with brachycephaly (17), anterior plagiocephaly (unilateral coronal synostosis; 16), trigonocephaly (11), multisuture craniosynostosis (7), and Cohen's craniotelencephalic dysplasia (1). The mean age at the time of the operation was 8 months and the mean follow up was 17 months. Eight patients experienced complications related to the resorbable material. Seven of the eight had complete resolution of symptoms after conservative treatment and one patient had complete resolution of the skin infection after plate removal. The purpose of this study was to evaluate the risks and complications with the use of resorbable material to establish guidelines for avoidance of surgical pitfalls that lead to increased risk of morbidity with the use of this material, particularly as it relates to plate visibility under the skin, plate palpability, skin breakdown, and skin infections over the plating system.

Impact of significant weight loss on outcome of body-contouring surgery.

Morbid obesity in the United States has reached startling proportions, with serious physical and psychosocial ramifications. As the number of patients undergoing bariatric surgery increases to treat this problem, it is expected there will be an increase in the number of patients presenting to plastic surgery offices for body contouring after weight loss. It is imperative that plastic surgeons prepare patients with extreme weight loss as to the risks and complications as compared with the general population undergoing body contouring. In this retrospective chart review, 26 patients undergoing body contouring from May 2001 to November 2004 were reviewed. Only patients who had extreme weight loss, defined as losing greater than 50 pounds, were included in this study. The age, gender, amount of weight lost, comorbidities, tobacco use, and weight-loss method were recorded. Additionally, the type of body-contouring procedure and presence of complications were collected from the records. The percentage of complications in our patient population is significantly higher than reported in the literature for the general population undergoing an abdominoplasty. We believe the increased wound complications seen in our patients can be attributed to the inherent complications seen with obese patients.

Dermatofibrosarcoma protuberans of the face: surgical management.

Dermatofibrosarcoma protuberans (DFSP) is a locally aggressive, rarely metastatic, spindle cell tumor. It is most commonly found on the trunk and rarely on the head and neck. Recurrence has been found to be more common in the head and neck region, which may be attributable to delayed patient presentation or a reluctance for wide excision in that region. The authors report a rare case of DFSP presenting as a large mass of the face. Surgical treatment required aggressive local resection of the tumor, including the underlying maxillary antrum. The soft tissue was cleared by Mohs technique. More than one procedure was required to obtain clear bone margins. Adjuvant radiation therapy was used to gain local control. Reconstruction was performed using a cheek advancement flap, as well as a forehead flap and split-thickness graft to the donor site.

Cost-effective management of isolated facial fractures.

The purpose of this study was to evaluate the subset of costs incurred for surgical treatment of isolated midface and mandible fractures of patients admitted directly from the emergency department compared with those admitted as outpatients after evaluation and discharge from the emergency department. After institutional review board approval, the records of patients admitted to Wake Forest University Baptist Medical Center were studied retrospectively for patients who underwent surgical repair of an isolated facial fracture between July 1, 1999 and June 30, 2000. Patients were placed into one of two groups: admission from the emergency department versus admission as an out-patient. Total hospital charges were compared, and complications were evaluated. Mechanism of injury, age, and gender were recorded within each group. Forty-two patients met the study criteria. Twenty-eight patients were admitted directly from the emergency department (Group A), and 14 were admitted as outpatients after elective scheduling for operative repair (Group B). Operative charges based on utilization of time and materials showed no statistical significance between Group A (P = 0.275) and Group B (P = 0.393). Patients admitted directly from the emergency department had a mean hospital charge of 3,556.66 dollars higher (P< or = 0.001) and stayed 2 days longer in the hospital as compared with the outpatient group. No differences were noted in complications between the study groups. The results of this study reveal a significant decrease in cost for patients with isolated facial fractures admitted as outpatients on scheduling surgery as compared with immediate admission from the emergency department.

Dynamic spring-mediated cranioplasty in a rabbit model.

Since the beginning of craniofacial surgery, there has been an ongoing search for surgical techniques to enhance outcome while, at the same time, decreasing the invasiveness of the surgical treatment of craniofacial deformities. The purpose of this study was to test a recently reported minimally invasive treatment modality, the dynamic spring, in a rabbit calvarial model for efficacy and safety. Specifically, the results of spring cranioplasty on skull growth, the underlying brain, and adjacent bone were to be assessed. The study population consisted of 36 7-week-old New Zealand white rabbits. The rabbits were divided into four treatment groups (9 rabbits each): control, sham surgery, stainless steel springs, and memory metal springs. Postoperative analysis included weekly radiographs to evaluate movement of amalgam markers placed at standardized locations. Additionally, 16 rabbits (4 from each group) were killed at 14 days after surgery, and postmortem histological analysis was done. The remaining rabbits were followed until they were adults and were then killed and similarly analyzed. No morbidity or mortality occurred in the immediate perioperative period secondary to the surgery. Postmortem histological analysis of all study animals revealed no intracranial, subcutaneous, or skin infections and no technical complications related to the surgery. Statistical analysis using ANOVA and pair-wise comparisons between treatment groups revealed a statistically significant difference (P < 0.05) between the marker movement in the spring groups versus the sham and control groups. There were no significant differences between the sham and control groups or between the two spring groups. In conclusion, this study confirms the efficacy and safety of the dynamic spring in a rabbit model.
