RESUMO
BACKGROUND: The deep inferior epigastric artery perforator (DIEP) flap is the gold standard in autologous breast reconstruction. Despite advances in perforator dissection, abdominal morbidity still occurs. Traditional rectus diastasis (RD), abdominal bulge, and hernia repair with open techniques are associated with higher complication rates and recurrence. OBJECTIVES: We present a novel case series of robotic repair of symptomatic RD and/or abdominal bulge with concurrent hernia following DIEP flap surgery. METHODS: A single-center, retrospective review was conducted of 10 patients who underwent bilateral DIEP flap breast reconstruction and subsequent robotic repair of RD and/or abdominal bulge and hernia. Preoperative demographics and postoperative clinical outcomes were reviewed. RD up to 5 cm, abdominal bulge, and any concurrent ventral/umbilical hernias were repaired robotically with retrorectus plication and macroporous mesh reinforcement. RESULTS: The average age and BMI were 49 years (range 41-63) and 31â kg/m2 (range 26-44), respectively. The average number of perforators harvested per flap was 2.5 (range 1-4). Average RD and hernia size were 3.95â cm (range 2-5) and 5.8â cm2 (1-15), respectively. Eight patients stayed 1 night in the hospital, and 2 went home the same day as the robotic repair. No patients were converted to open technique and none experienced complications within 30 days. CONCLUSIONS: For patients who experience donor site morbidity following DIEP flap breast reconstruction, minimally invasive robotic repair of RD and/or abdominal bulge with hernia can be performed with mesh reinforcement. This technique is effective, with low complication rates, and should be considered over open repair.

BACKGROUND: Primary hypercoagulable disorders pose a significant challenge to microsurgeons and have traditionally been regarded as a relative contraindication to free tissue transfer. Since free flaps offer numerous advantages in breast reconstruction, there is an effort to expand the population to whom these operations can be safely offered. The purpose of this study is to describe our chemoprophylaxis regimen in cases of primary hypercoagulability, as well as to compare flap outcomes and complications between women with and without hypercoagulability. PATIENTS AND METHODS: A single institution retrospective review identified 15 patients (25 flaps) with known primary hypercoagulability who underwent microsurgical breast reconstruction from 2010 through 2020. There were 785 patients (1268 flaps) without primary hypercoagulability who underwent microsurgical breast reconstruction, including 40 patients (73 flaps) with a history of venous thromboembolism (VTE), evaluated for comparison. Patient characteristics, thromboprophylaxis regimen, and surgical outcomes were collected. In carrying out this cohort study, we have adhered to Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. RESULTS: Fifteen patients with primary hypercoagulability were identified, including heterozygous factor V Leiden mutation (n = 12), protein S deficiency (n = 1), prothrombin mutation (n = 1), and primary antiphospholipid syndrome (n = 1). Thirteen of these (87%) were discharged with an extended LMWH course. There was no postoperative VTE or mortality in this cohort, and no significant difference in hematoma or transfusion compared with the control group (p = .31, p = .87, respectively). The flap loss rate was 4% in the hypercoagulable group compared with 0.92% in the control group (p = .15). The salvage for arterial or venous compromise in the hypercoagulable group was poor (0% vs. 52%, p = .3). CONCLUSION: Microsurgical breast reconstruction in women with primary hypercoagulability disorders is feasible with acceptable risk of flap loss but poor salvage potential. Postoperative thromboprophylaxis with extended prophylactic LMWH in this population appears to be a safe regimen.

INTRODUCTION: Obesity is a risk factor for complications following autologous breast reconstruction. Little is known regarding outcomes based on the degree of obesity. This study compares breast reconstruction outcomes and complication rates for the three classes defined by the body mass index (BMI)-based WHO classification. METHODS: The authors conducted a retrospective chart review identifying obese patients who underwent abdominally based breast reconstruction between January 2011 and January 2021. Patients were stratified by BMI class [class 1 (C1) = 30-34.99 kg/m2, class 2 (C2) = 35-39.99 kg/m2, and class 3 (C3) = 40 kg/m2 + ]. Outcomes were compared. RESULTS: A total of 232 patients (395 flaps) were included with 138 patients were classified as C1, 68 patients as C2, and 26 patients as C3. Rates of any complication (80%) and at least one major complication (31%) did not vary significantly (P = 0.057, 0.185). Individual rates of 30-day readmission (18%) or reoperation (26%) did not vary significantly (P = 0.588 and 0.059). Rates of seroma (C1 = 15%, C2 = 16%, and C3 = 35%), hernia (C1 = 0%, C2 = 4%, and C3 = 8%), and incisional dehiscence (C1 = 30%, C2 = 44%, and C3 = 62%) were associated with significantly increased risk with higher classes of obesity (P < 0.05). The rate of flap failure did not vary significantly (P = 0.573). CONCLUSION: The risk of major complications and total flap loss associated with abdominally based breast reconstruction does not differ between the classes of obesity. Although complication rates are high overall in the obese population, detrimental complications do not vary between the classes. Patients should be counseled regarding their individual risk without the need for arbitrary BMI cutoffs.

Background: Dupuytren disease creates thickened cords of the palmar fascia, leading to progressive flexion contractures that severely hinder hand function. Collagenase clostridium histolyticum (CCH) injection is a common, minimally invasive alternative to surgical excision of these cords. The impact of CCH injection on the histological architecture of Dupuytren cords has not been studied extensively. Methods: A series of 10 CCH-injected cords were evaluated histologically. Cellularity, architecture, and connective tissue organization were compared against uninjected Dupuytren cords and normal palmar fascia. Results: No significant histopathological differences between CCH-injected and CCH-uninjected cords were identified. Conclusions: Dupuytren cords do not demonstrate histological changes with prior exposure to CCH.

Lower extremity wounds associated with fractures and bony defects often require secondary orthopedic procedures after flap coverage has been performed. In this study, we compare complications between muscle and fasciocutaneous flaps after secondary orthopedic procedures. A retrospective chart review study of all lower extremity soft tissue reconstructions by a single surgeon over seven years yielded a subgroup of patients who underwent secondary orthopedic procedures, including hardware removal, hardware revision, and bone grafting after flap reconstruction. Of 355 lower extremity, soft tissue reconstructions for orthopedic coverage performed in the time period studied, 102 patients underwent secondary orthopedic procedures after flap reconstruction. Of these, 54 received muscle flaps (52.94%), and 48 received fasciocutaneous flaps (47.06%). Using this subgroup of 102 patients, we compared muscle and fasciocutaneous flaps using three categories of wound complications following these secondary procedures: There were no superficial wounds requiring local wound care only in the muscle flap group (0%, n = 0) versus 4.17% (n = 2; p = 0.130) in the fasciocutaneous flap group. There were 2 lost flaps requiring surgical debridement and additional skin grafting in the muscle flaps group (3.70%) versus 2 (4.17%; p = 0.904) in the fasciocutaneous flap group. In the third category, flap loss requiring additional soft tissue reconstruction was 18.52% (n = 10) in the muscle group versus 2.08% (n = 1; p = 0.008) in the fasciocutaneous flap group. Our data support the existing literature indicating that fasciocutaneous flaps can tolerate secondary procedures better than muscle flaps and should initially be considered in patients with higher probability of needing additional orthopedic procedures after reconstruction.

Targeted muscle reinnervation (TMR) is a powerful new tool in preventing and treating residual limb and phantom limb pain. In the adult population, TMR is rapidly becoming standard of care; however, there is a paucity of literature regarding indications and outcomes of TMR in the pediatric population. We present 2 cases of pediatric patients who sustained amputations and the relevant challenges associated with TMR in their cases. One is a 7-year-old patient who developed severe phantom and residual limb pain after a posttraumatic above-knee amputation. He failed pharmacologic measures and underwent TMR. He obtained complete relief of his symptoms and is continuing to do well 1.5 years postoperatively. The other is a 2-year-old boy with bilateral wrist and below-knee amputations as sequelae of sepsis. TMR was not performed because the patient never demonstrated evidence of phantom limb pain or symptomatic neuroma formation. We use these 2 cases to explore the challenges particular to pediatric patients when considering treatment with TMR, including capacity to report pain, risks of anesthesia, and cortical plasticity. These issues will be critical in determining how TMR will be applied to pediatric patients.

BACKGROUND: To evaluate the impact of postoperative depth of sedation in free flap transfers to the head and neck. METHODS: A single center, retrospective cohort of 92 patients were stratified by depth of sedation, light sedation (RASS -1 or greater) or deep sedation (RASS less than -1), and analyzed for postoperative flap and medical complications. RESULTS: Of the 92 patients 45 were included in the light sedation and 47 in the deep sedation group. Flap complication requiring return to the operating room occurred in 8 (22.2%) patients in light sedation compared to 12 (27.7%) (p = 0.450) patients in deep sedation. A composite outcome of flap and medical complications occurred less frequently in the light sedation group 14 (31.8%) compared to deep sedation 32 (69.6%) (p < 0.001). CONCLUSION: There was no difference in return to the operating room between the two groups. Light sedation had reduced incidence of medical complications compared to deep.

BACKGROUND: In the United States, approximately 30% of about 10,000 annual blast injuries involve the hand, causing a broad spectrum of injury severity. The first web space is typically most severely affected. As the carpometacarpal (CMC) joint is critical to the unique function of the thumb, we evaluated typical patterns of injury to this joint, subsequent salvageability and functional outcomes of the thumb. METHODS: We conducted a retrospective chart review on patients with blast injuries to the hand from January 1995 through July 2019 and excluded penetrating trauma. We assessed hand function as reported in occupational therapy records. Injury severity was classified independently by structures. RESULTS: Twenty-one patients were included, two with bilateral injuries, for a total of 23 hands. Eighteen patients had injuries to one or both thumbs, for a total of 20 thumbs evaluated. Average follow-up was 1.58 years. Most injuries qualified as severe in at least one category: soft tissue, neurovascular, or bone/joint. All 10 CMC joint dislocations required surgical fixation and pinning. Eight patients had applicable occupational therapy notes available. Severely injured thumbs had statistically significant decreased range of motion (ROM) at the interphalangeal joint, metacarpophalangeal joint and with radial abduction compared to mildly injury thumbs (P value 0.02, 0.03, 0.04, respectively). CONCLUSIONS: Blast injury to the hand often results in severe deficits, frequently affecting thumb functionality and irreversibly altering occupational capabilities. Half the patients studied had severe damage to the thumb CMC joint. Objectively, severely injured thumbs had significantly worse ROM than mildly injured thumbs.
RESUMO
BACKGROUND: Cosmetic surgery tourism is increasing exponentially. Patients seek cosmetic procedures within the United States and abroad, lured by lower cost procedures, shorter waiting lists, and affordable airfare and hotel accommodations. Unfortunately, operations are often performed by non-board-certified plastic surgeons, sometimes not even by plastic surgeons. Preoperative counseling, frequently limited to a video-chat with an office secretary, provides inadequate discussion regarding potential complications. Postoperative care is careless and rarely involves the operating surgeon. Complications are frequent, with management falling into the hands of plastic surgeons unfamiliar with the patient's care. Furthermore, the physician, rather than the patient or hospital, faces the largest cost burden. OBJECTIVES: The authors sought to explore their institution's experience treating complications of cosmetic tourism and investigate associated costs. METHODS: The retrospective review of 16 patients treated for complications related to cosmetic surgery tourism plus cost analysis revealed a substantial discrepancy between money saved by undergoing surgery abroad and massive costs accrued to treat surgical complications. RESULTS: The most common complication was infection, often requiring surgery or IV antibiotics on discharge. Mean cost per patient was $26,657.19, ranging from $392 (single outpatient visit) to $154,700.79 (prolonged admission and surgery). Overall, the hospital retained 63% of billed charges, while physicians retained only 9%. The greatest amount paid by any single patient was $2635.00 by a patient with private insurance. CONCLUSIONS: Cosmetic tourism has severe medical repercussions for patients and complications that burden hospitals, physicians, and the US medical system. Physicians treating the complications suffer the greatest financial loss.

BACKGROUND: Anatomical studies have identified separate superficial and deep facial fat compartments, leading some to theorize that volume loss from the deep midface causes overlying superficial fat pseudoptosis. Unfortunately, a paucity of evidence exists regarding whether facial fat volume is truly lost with age and, if so, whether it is lost equally or differentially from the superficial and deep compartments. The aim of this study was to quantify volume changes occurring with age within the superficial, deep, and buccal fat compartments of the midface. METHODS: A retrospective longitudinal study was performed evaluating individuals aged 30 to 65 years who underwent facial computed tomography followed by facial computed tomography greater than or equal to 10 years later. Superficial midface, deep midface, and buccal fat volumes were quantified using Horos radiology software. RESULTS: Nineteen subjects met inclusion criteria. Mean total fat volume decreased significantly from 46.47 cc to 40.81 cc (p < 0.01). The mean superficial and deep fat volumes both decreased significantly from 26.10 cc to 23.15 cc (p < 0.01) and from 11.01 cc to 8.98 cc (p < 0.01), respectively. No significant difference was observed in buccal fat volume over time (9.36 cc to 8.68 cc; p = 0.04). Patients lost an average of 11.3 percent of their initial superficial fat volume and 18.4 percent of their initial deep fat volume. CONCLUSIONS: Significant volume loss was observed from both superficial and deep facial fat compartments over a mean 11.3 years. Patients lost a greater percentage of deep facial fat volume, providing support for the theory of pseudoptosis caused by deep midface fat loss.

BACKGROUND: Body mass index (BMI) has long been the proxy for patient selection in obese patients presenting for abdominally based breast reconstruction. BMI, however, fails to accurately reflect the distribution of abdominal adipose tissue. This study aims to quantify the effect of abdominal wall thickness on the incidence of post-operative complications and contrast abdominal wall thickness and BMI as predictors of post-operative morbidity. METHODS: We performed a retrospective review of 106 consecutive patients who underwent abdominally based breast reconstruction. Abdominal wall thickness was quantified using preoperative CT angiograms. Primary outcomes included delayed wound healing (abdomen and/or breast), flap fat necrosis, return to OR in 30 days, infection, and flap loss. RESULTS: Patients experiencing delayed abdominal wound healing (n=38), delayed breast wound healing (n=27), and flap fat necrosis (n=24) had significantly thicker abdominal wall measurements (p<0.0015). Of the 24 patients with palpable fat necrosis, 11 required excision. Increasing abdominal wall thickness significantly increased the odds of delayed abdominal wound healing (p=0.0005), delayed breast wound healing (p=0.0009), flap fat necrosis (p=0.0028), and infection (p=0.0198). Compared to BMI, abdominal wall thickness proved to be a more accurate predictor of delayed breast wound healing, any delayed wound healing, flap fat necrosis, and infection. CONCLUSIONS: Our data indicate that as abdominal wall thickness increases, so does the risk of postoperative morbidity. Abdominal wall thickness outperformed BMI as a predictor of postoperative morbidity in several areas. This suggests that objective data obtained from preoperative CT scans may allow more accurate, individualized perioperative risk assessment.

BACKGROUND: Both stenosing tenosynovitis and Dupuytren's contracture are common conditions encountered in hand surgery. Connections between 2 diseases have been suggested in literature. The purpose of this study was to examine whether there's an association between the 2 processes. METHODS: A retrospective chart review was performed to include all patients seen by a single surgeon between 2014 and 2017 with the diagnosis of either trigger finger or Dupuytren's contracture in the same hand. Patients' demographics, medical history, social and surgical histories are recorded. Univariate and multivariate analysis were conducted. RESULTS: A cohort of 238 patients was identified. One hundred ninety-two patients were diagnosed with trigger finger. Eighty-nine patients were diagnosed with Dupuytren's contracture. Forty-three patients carried both diagnoses. Median age was 61.6 (56-72). Half were male (50.4%) and 66.8% reported current alcohol intake. Other factors include history of former or current tobacco use (52.9%), diabetes (23.9%), and manual labor (31.1%). In the univariate model, trigger finger, sex, and age were significantly associated with the diagnosis of Dupuytren's contracture, and Dupuytren's contracture and sex were significantly associated with the trigger finger diagnosis. Diabetes, manual labor, use of alcohol and tobacco were not significant. In the multivariate model, age and trigger finger were significantly associated with Dupuytren's contracture. CONCLUSIONS: Significant association between stenosing tenosynovitis and Dupuytren's contracture was identified in our patient cohort. Patients with stenosing tenosynovitis may be at an increased risk of developing Dupuytren's contracture or vice versa.
RESUMO
BACKGROUND: Lipomas are common benign tumors. When they develop in proximity to peripheral nerves, they can cause neurologic symptoms secondary to mass effect. Previous reports have shown symptom resolution after removal of lipomas compressing various upper extremity peripheral nerves. However, brachial plexus lipomas are relatively rare. Our multidisciplinary experience with brachial plexus lipoma resection is reviewed in the largest case series to date. METHODS: A retrospective chart review of all patients undergoing resection of brachial plexus lipomatous tumors between 2006 and 2016 was performed. Patient demographic data, diagnostic imaging, clinical presentation, operative details, surgical pathology, and clinical outcomes were reviewed. RESULTS: Twelve brachial plexus lipomatous tumors were resected in 11 patients: 10 lipomas, 1 hibernoma, and 1 atypical lipomatous tumor. The most common tumor location was supraclavicular (50%), followed by axillary (42%), and proximal medial arm (8%). The most common brachial plexus segment involved was the upper trunk (50%), followed by posterior cord (25%), lateral pectoral nerve (8%), lower trunk (8%), and proximal median nerve (8%). Most patients presented with an enlarging painless mass (58%). Of the patients who presented with neurologic symptoms, symptoms resolved in the majority (80%). CONCLUSIONS: Brachial plexus lipomas are rare causes of compression neuropathy in the upper extremity. Careful resection and knowledge of brachial plexus anatomy, which may be distorted by the tumor, are critical to achieving a successful surgical outcome with predictable symptom resolution. Finally, surveillance magnetic resonance imaging may be warranted for atypical lesions.

BACKGROUND: Cranial bone grafting for an alveolar cleft obtains membranous bone from a low-morbidity donor site. Although iliac crest bone is the favored donor site, there are no objective analyses of three-dimensional radiologic outcomes with cranial bone grafting and no studies evaluating complications and long-term outcomes in a large series of patients undergoing cranial bone grafting. METHODS: A retrospective chart review was conducted on patients who underwent alveolar bone grafting from the cranium over a 25-year period performed by a single surgeon. Data collected included patient characteristics, complications, and clinical outcomes. Radiologic analysis of graft outcomes was determined using Amira volume-rendering software on the most recent 10 consecutive patients. RESULTS: The authors' study cohort included 308 patients, with an average age of 11.5 years. Complications involved harvesting the graft in 3.5 percent, the donor site in 1 percent, and the recipient site in 17.2 percent. Regrafting was required in 7.1 percent, with a clinical success rate of 92.9 percent. The average alveolar defect was 1.19 ml preoperatively and 0.19 ml postoperatively, with 85 percent fill of the cleft defect by radiologic analysis. CONCLUSIONS: Cranial bone grafting for the alveolar cleft is a low-morbidity operation and has success similar to that of iliac crest bone grafting. It should be considered more often as a viable option for the alveolar cleft patient. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

BACKGROUND: Patients with cleft lip and palate demonstrate a spectrum of maxillary growth deficiencies. The purpose of this study was to review the authors' experience in the treatment of midface hypoplasia in nonsyndromic cleft lip-cleft palate patients using rotation advancement of the midface with Le Fort III distraction. METHODS: A retrospective chart review was conducted to include all patients with nonsyndromic cleft lip and/or cleft palate who underwent Le Fort III rotation advancement of the midface from 1999 to 2011. Along with standard outcome measures, Amira imaging software was used to perform surface analysis on the last five consecutive patients in this series. RESULTS: Forty-three consecutive patients met inclusion criteria. Diagnoses included unilateral complete cleft lip and palate (n = 25) and bilateral complete cleft lip and palate (n = 18). Average distraction distance measured 10.1 mm at the level of the zygoma (range, 6 to 15 mm). Preoperative and 6-month postoperative sella, nasion, A point angles measured 76.3 and 81.8 degrees; whereas sella, nasion, B point angles measured 79.9 and 78.7 degrees, respectively. Preoperative and 6-month postoperative overjet measured -5.4 and 3.2 mm, whereas overbite measured 1.9 and 1.1 mm, respectively. Six patients (13 percent) developed pseudorelapse, with five patients going on to have subsequent Le Fort I advancement at an average of 7 years after distraction (range, 2 to 11 years). CONCLUSIONS: Le Fort III rotation advancement of the midface addresses severe midface deficiencies in select patients. Whereas older techniques target occlusal correction alone, extending osteotomies to the Le Fort III level allows occlusal correction along with improvements in malar and nasal projection required to achieve facial harmony in this group of patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Extramammary Paget's disease is a rare intraepithelial adenocarcinoma typified histologically by the presence of Paget cells. Treatment has historically been surgical, with wide excision being the standard of care. However, due to clinically indeterminate margins and diffuse spread, local recurrence rates remain high. Mohs micrographic surgery has been proposed to improve the rate of local recurrence. Application of Mohs technique to treat extramammary Paget's disease can be difficult because of the large size of these lesions. Reported excisions either involved lengthy procedures or peripheral Mohs modification. The peripheral technique does not evaluate the depth of the central lesion, yet prognosis and lymph node involvement are directly related to the degree of vertical invasion. In this study, we discuss our experience with extramammary Paget's disease, along with a novel approach to treatment by using a modification of peripheral Mohs micrographic surgery that incorporates histologic analysis of the central specimen's depth.

The purpose of this study is to develop a rodent functional magnetic resonance imaging (fMRI) survival model with the use of heparin-coated vascular access devices. Such a model would ease the administration of sedative agents, reduce the number of animals required in survival experiments and eliminate animal-to-animal variability seen in previous designs. Seven male Sprague-Dawley rats underwent surgical placement of an MRI-compatible vascular access port, followed by implantable electrode placement on the right median nerve. Functional MRI during nerve stimulation and resting-state functional connectivity MRI (fcMRI) were performed at times 0, 2, 4, 8 and 12 weeks postoperatively using a 9.4T scanner. Anesthesia was maintained using intravenous dexmedetomidine and reversed using atipamezole. There were no fatalities or infectious complications during this study. All vascular access ports remained patent. Blood oxygen level dependent (BOLD) activation by electrical stimulation of the median nerve using implanted electrodes was seen within the forelimb sensory region (S1FL) for all animals at all time points. The number of activated voxels decreased at time points 4 and 8 weeks, returning to a normal level at 12 weeks, which is attributed to scar tissue formation and resolution around the embedded electrode. The applications of this experiment extend far beyond the scope of peripheral nerve experimentation. These vascular access ports can be applied to any survival MRI study requiring repeated medication administration, intravenous contrast, or blood sampling.

BACKGROUND: Although multiple methods of tongue reduction have been described, recent literature suggests that the central reductions may be more favorable in patients with Beckwith-Wiedemann syndrome (BWS). In this case series, we review our experience with macroglossia associated with BWS, and we offer a new technique of central tongue reduction. METHODS: Between 1993 and 2007, a retrospective chart review was conducted to include all patients with a diagnosis of BWS who have undergone stellate or double stellate tongue reduction at the Children's Hospital of Wisconsin. RESULTS: A total of 7 patients met all inclusion criteria. All patients had good tongue mobility at 1-year follow-up. One patient required speech therapy for persistent articulation errors postoperatively. A total of 2 patients required secondary procedures for recurrent macroglossia. There were no complaints of abnormal taste or sensation. CONCLUSIONS: The stellate and double stellate tongue reductions provide effective treatment in macroglossia associated with BWS.

BACKGROUND: Patients with velocardiofacial syndrome often present with refractory velopharyngeal incompetence. Whereas the high wide pharyngeal flap has been advocated for these patients, poor visualization makes high inset of the flap technically difficult. We present a consecutive series of patients with velocardiofacial syndrome and severe velopharyngeal incompetence treated with high inset pharyngeal flap achieved by through-and-through dissection of the soft palate. METHODS: All patients with velocardiofacial syndrome in whom secondary surgical management was recommended for treatment of severe velopharyngeal incompetence over the last 7 years were treated with a high inset pharyngeal flap achieved by through-and-through dissection of the soft palate (to be described). All patients had nasendoscopy and videofluoroscopy preoperatively and underwent perceptual speech assessment preoperatively and at least 12 months postoperatively. RESULTS: Eight patients met the inclusion criteria with a mean age at presentation of 7 years, 3 months. No patient had a history of cleft palate. All patients had minimal lateral pharyngeal wall motion and a medium to large velopharyngeal gap (>6 mm). Velopharyngeal incompetence, as measured by perceptual speech score, improved from a mean of 10.3 (range, 9 to 12 on a maximum scale of 13) to a mean of 1.9 (range, 0 to 4), achieving velopharyngeal competence (p < 0.01) without nasal airway obstruction in any patient. CONCLUSIONS: The present report demonstrates restoration of velopharyngeal competence in a consecutive series of patients with velocardiofacial syndrome who presented with severe velopharyngeal incompetence. We attribute this outcome to the development of a reliable technique for high inset of the pharyngeal flap using through-and-through dissection of the soft palate, enabling direct visualization of flap placement.
