Staged Head and Neck Reconstruction: Heresy or a Reasoned Approach in a Select Group of Patients?

Study Design: case series. Objective: The restoration of defects in a single procedure with microvascular free flap reconstruction has become a mainstay of head and neck surgery. Yet in patients with complex defects and pre-existing comorbid medical conditions, a staged-reconstructive approach can enhance the safety of the procedure and improve the patient's outcome. Methods: We present 3 representative case examples of a larger series of patients who underwent reconstruction of major defects and discuss the usefulness of a staged-reconstructive approach in the management of complex patients. Results: All 3 patients, with an existing composite defect in the setting of prior radiation therapy, underwent successful staged-reconstructive surgery using a variety of free tissue and regional flap transfers. Conclusions: A staged approach facilitates the reconstruction of complex composite defects, increases vessel availability, and mitigates the risk of flap failure. Although this approach commits the patient to multiple procedures and a more prolonged plan of care, it is preferable to 1 operation in specific complex situations with adverse, high-risk clinical features.

Diagnosis and management of pharyngoesophageal stenosis: A comprehensive approach to prophylactic, endoscopic, and reconstructive treatment options.

BACKGROUND: Pharyngoesophageal stenosis (PES) is a serious complication that substantially impacts functional outcomes and quality of life (QOL) for up to a third of head and neck cancer patients who undergo radiotherapy. Dysphagia is often multifactorial in nature and is a devastating complication of treatment that impacts patients' QOL, general health and overall wellbeing. The authors detail the clinical presentation, risk factors, imaging characteristics, preventive measures, and multimodality treatment options for PES. METHODS: The authors present a comprehensive management algorithm for PES, including treatment by dilation, stenting, spray cryotherapy and dilation, and reconstructive treatment options utilizing different pedicled and free flaps. RESULTS: The authors advocate for a thorough assessment of the extent and degree of pharyngoesophageal involvement of PES to determine the optimal management strategy. CONCLUSIONS: The development of post treatment dysphagia requires appropriate imaging and biopsy, when indicated, to rule out the presence of persistent/recurrent cancer. Multidisciplinary management by a team of physicians well-versed in the range of diagnostic and therapeutic interventions available for PES is critical to its successful management.

Radiation necrosis of the pharyngeal soft tissue: Unique clinical entity reconstructed with a previously unreported composite brachioradialis and flexor digitorum superficialis radial forearm flap.

BACKGROUND: The radial forearm free flap (RFFF) is a versatile flap commonly used in head and neck reconstructive surgery. We describe the use of a composite RFFF that includes muscle for reconstruction of a hostile wound of the posterior pharyngeal wall. METHODS: A 54-year-old male with a history of recurrent right palatine tonsil HPV+ squamous cell carcinoma developed severe soft tissue necrosis of the posterior pharyngeal wall secondary to reirradiation. The defect was reconstructed with a composite RFFF that included the brachioradialis (BR) muscle and the flexor digitorum superficialis (FDS) muscle. RESULTS: Restoration of this complex defect was successfully accomplished with minimal donor site functional deficits and satisfactory functional outcomes including decannulation and resumption of oral intake. CONCLUSION: This composite RFFF can be effectively used to reconstruct a hostile wound of the posterior pharyngeal wall. Incorporation of muscle in the reconstruction of complex wounds with soft tissue necrosis is beneficial.

Incongruent radiographic indication of calvarial metastatic diploic space invasion with absent histologic findings in a patient with basal cell carcinoma of the scalp.

BACKGROUND: Radiographic imaging is often used to determine basal cell carcinoma (BCC) extension and invasion and to define a surgical plan. However, imaging modalities may overestimate tumor invasion and lead to unnecessarily aggressive treatment. METHODS: A 77-year-old woman was seen with a growing BCC of the scalp with MRI imaging indicative of calvarial diploic space invasion. The patient underwent Mohs surgery followed by a parietal craniectomy. RESULTS: Contrary to the MRI findings, histological evaluation of the cortical parietal calvarium and the diploic space did not demonstrate BCC. CONCLUSIONS: Surgeons should be wary of diploic space changes in the absence of cortical erosion demonstrated in MRI as it may not explicitly indicate tumor invasion. Biopsy of the diploe is necessary in such cases to determine the surgical course and to avoid morbidity associated with calvarium removal.

Responsiveness of acoustic rhinometry to septorhinoplasty by comparison with rhinomanometry and subjective instruments.

OBJECTIVES: Nose patency measures and instruments assessing subjective health are increasingly being used in rhinology. However, there is very little evidence of comparing existing methods' responsiveness to change. We evaluated the responsiveness of acoustic rhinometry to nasal valve surgery by comparison with rhinomanometry and patient-reported outcome instruments. DESIGN: Prospective case-control study. SETTING: Tertiary referral University Hospital. PARTICIPANTS: Sixty consecutive patients with internal nasal valve dysfunction and 20 healthy volunteers as control group were enrolled. Prospectively collected data included acoustic rhinometry, rhinomanometry, NOSE scale, SNOT-23 questionnaire, visual analogue scale and demographics. MAIN OUTCOME MEASURES: Primary endpoint was the responsiveness of acoustic rhinometry to functional septorhinoplasty surgery at 3 months. Secondary endpoints were ability of acoustic rhinometry to reflect "known group" differences and correlation to subjective symptoms. RESULTS: Acoustic rhinometry was highly responsive to septorhinoplasty (P < 0.0001) while anterior rhinomanometry was not (P = 0.08). Based on the quartiles of the postoperative change in NOSE score, patients were classified as, respectively, non-responders, mild, moderate and good responders to surgery. Logistic regression model showed that acoustic rhinometry was able to discriminate non-responders to responders to surgery (P = 0.019), while anterior rhinomanometry failed (P = 0.611). Sensitivity and specificity of acoustic rhinometry were significantly higher (ROC area = 0.76) than rhinomanometry (ROC area = 0.48). Acoustic rhinometry was also superior than rhinomanometry to discriminate patients from control subjects and agreed better with patients-based subjective questionnaires. CONCLUSIONS: Our study confirms and quantifies the responsiveness of acoustic rhinometry to nasal valve surgery, with a higher sensitivity and specificity than rhinomanometry.

Blood Cyst of the Anterior Leaflet of the Mitral Valve in an Asymptomatic Adult: Is Surgery an Objective?

Blood cysts of the heart are rare benign tumors that usually involve the cardiac valves and are mainly found in fetuses and very early in life. However, no consensus on the surgical management of asymptomatic cases has been postulated. We believe surgical resection should be performed in patients with symptoms, tumor growth, and valvular dysfunction. We report a case of a blood cyst of the anterior leaflet of the mitral valve, which was incidentally discovered in a 55-year-old man.

Skeletal and soft tissue changes and stability in cleft lip and palate patients after distraction osteogenesis using a new intraoral maxillary device.

BACKGROUND: The authors have recently reported on the use of an internal maxillary distraction device. In this study, we report on the hard and soft tissue movements achieved with this intraoral distraction device, and the stability changes after distraction osteogenesis for maxillary hypoplasia in patients with cleft lip and palate. METHODS: Ten male patients with severe hypoplasia of the maxilla, with complete uni- or bilateral cleft lip and palate were included. The mean age of the patients at the time of operation was 11.91 years (±3.41). To evaluate the distraction process and stability, superimpositions on the preoperative lateral cephalograms were performed. The mean follow-up (FU) was 15.42 months (±3.94). RESULTS: Cephalometric measurements at all of the maxillary hard and soft tissue points improved significantly. Maxillary point A was advanced by 8.25 mm (±3.17; P < 0.001). After distraction soft tissue point A' had advanced 7.10 mm (±2.69; P < 0.001). The soft tissue to hard tissue ratio at point A was 0.86:1 after distraction. Maxillary horizontal relapse at point A was 14.1% at FU. Vertical relapse was not significant. CONCLUSION: This rigid intraoral distraction device can be successfully used in the correction of severe maxillary hypoplasia. The marked aesthetic improvement and low psychological encumbrance make this device viable for the treatment of cleft-related hypoplasia of the maxilla.

Survival predictors in ventricular assist device patients with prior extracorporeal life support: selecting appropriate candidates.

Several centers turn patients down for long-term ventricular assist devices (VADs) once they have received extracorporeal life support (ECLS) due to the expected poor outcome in these patients. The aim of this study was to identify survival predictors in this cohort of patients. Data of patients undergoing VAD support between January 2010 and November 2013 were retrospectively reviewed. Patients on ECLS support before implantation were considered eligible for inclusion. Outcome in survivors following long-term VAD support was compared with outcomes in nonsurvivors. Student's t-test and χ(2)-test were used as applicable. A total of 65 long-term VADs were implanted. The inclusion criteria were met by 24 patients. Eight patients did not survive the first 30 days. All preoperative characteristics were comparable between the two groups except for statistically higher Model for End-stage Liver Disease (MELD) score, bilirubin, white blood cell count, and blood urea nitrogen in nonsurvivors (P = 0.002, 0.01, 0.01, and 0.003, respectively). Stepwise discriminant analysis revealed MELD score as the most important survival predictor. Based on this analysis, an outcome predictor formula was generated. The 30-day and 1-year survival rates were 67% and 54%, respectively. In this study, we were able to determine survival predictors in VAD patients with prior ECLS support. The outcome in these patients is limited and associated with higher postoperative complications, particularly right ventricular and respiratory failure. The pre-VAD MELD score is an important predictor of poor outcome.

Successful acute type A aortic dissection repair in a nonagenarian.

Surgical repair in older patients with acute type A aortic dissection (ATAAD) evokes a higher peri- and postoperative mortality, it therefore remains controversial in nonagenarians. The authors present a case of a surgically managed ATAAD in a nonagenerian, a 94-year-old man presented with an uncomplicated ATAAD, necessitating emergency surgical repair. The subsequent postoperative course was uneventful, and the patient was discharged after uncomplicated recovery. Aggressive surgical approach should be feasable in select nonagenarian patients with ATAAD, depending on the clinical presention and prior patient history.

Endovascular stenting as treatment for occult perforated abdominal aorta caused by acute necrotizing pancreatitis as rare complication after heart transplantation.

With an increase in the population of living cardiac allograft recipients, noncardiac surgery in this group of patients will be a more frequent phenomenon. The postoperative management in these patients is, however, complex. The authors present a case of an abdominal aortic rupture due to the involvement of a necrotizing pancreatitis caused by the side effects of immunosuppressive therapy. A 48-year-old man presented with a necrotizing pancreatitis with accidental affection of the abdominal aortic wall, necessitating emergency repair. Open surgical repair was considered too precarious in a cardiac allograft recipient, aortic stent-graft through endovascular surgery was therefore opted as the preferred procedure. The subsequent postoperative course was uneventful and patient could be discharged.

Infant Odontogenic Myxoma: a specific entity.

INTRODUCTION: In children, and specifically in infants, odontogenic myxomas are extremely rare. In infants, myxoma seems to display mostly the same clinical, radiological and pathological characteristics. This paper presents a series of odontogenic myxomas in infant patients. MATERIALS AND METHODS: Four infant patients were included in this retrospective study. The clinical, radiological and pathological presentation was characterized and the treatment analysed. RESULTS: All patients presented with a rapidly evolving paranasal swelling. CT-scan showed a maxillary homogeneous unilocular and intraosseous tumour. In all cases, pathological examination revealed a loose myxoid stroma within stellate and spindle shaped cells. All patients underwent conservative surgery through a vestibular approach. CONCLUSION: This patient series and a review of the literature demonstrates that odontogenic myxoma is specific in infant. We propose the name of Infant Odontogenic Myxoma for this entity.

Specificity of paediatric jawbone lesions: tumours and pseudotumours.

INTRODUCTION: Characteristics and epidemiology of jaw tumours have been described mostly in adults. Compared with their adult counterparts, childhood jaw tumours show considerable differences. The aim of this study was to describe the different jaw tumours in children, define diagnostic tools to determine their specificity and describe optimal treatment. METHODS: All children patients with jaw lesions, excluding cysts, apical granuloma and osteitis were included in our study between 1999 and 2009. The medical records were analyzed for clinical, radiological, and pathological findings, treatments and recurrences. RESULTS: Mean patient age was 10.9 years old, ranging from 2 months to 18 years old. Of the 63 lesions, 18 were odontogenic and 45 non-odontogenic lesions. 6% of all cases were malignant tumours; the mean age of presentation was 7.25 years old, [ranging from 0.2 to 18 years old]. Approximately 80% of the tumours developed after 6 years of age. Odontogenic tumours occurred more often after the age of 6. CONCLUSION: Compared with their adult counterpart, childhood jaw tumours show considerable differences in their clinical behaviour and radiological and pathological characteristics. Clinical features of some tumours can be specific to children. Tumourigenesis is related to dental development and facial growth. Conservative treatment should be considered.

Fat graft transfer in children's facial malformations: a prospective three-dimensional evaluation.

INTRODUCTION: Autologous fat grafting for volume augmentation in soft tissues has grown in popularity in the paediatric plastic surgery community, despite a lack of quantifiable evidence of graft survival and predictable outcomes for child patients. The objective of this study is to quantify, through an objective method, the rate of survival of fat grafting in children's reconstructive surgery. METHODS: Clinical evaluation of all children was performed under standardised conditions in a prospective fashion with a 1-year follow-up. All patients, under 18 years of age, were photographed with a three-dimensional imaging system. Data were analysed with three-dimensional analysing software to quantify the volume improvements postoperatively and during the follow-up. RESULTS: Eleven children were included and followed up for 12 months. The mean age was 7.4 years. The mean amount of fat grafted was 13 cm3. At the end of the follow-up, the mean survival rate of the fat grafted was 40%. Complementary fat grafts were needed in 27% of the cases. No significant complications occurred. CONCLUSION: Until now, the literature has failed to provide objective evidence of fat survival in children. This study, using three-dimensional data, showed a 40% survival of grafted fat. The use of three-dimensional photographs and analysis has great clinical potential for surgical planning and follow-up.

Use of the external pectoralis myocutaneous major flap in anterior skull base reconstruction.

Despite the emergence of free tissue transfer, the pectoralis major myocutaneous flap (PMMF) still has a role in anterior base skull reconstruction (when free tissue transfer is not feasible). The aim of this study is to evaluate the results of external PMMF in anterior skull base reconstruction. A retrospective study from 1977 to 2006 was conducted at Yale New Haven Hospital. 16 patients (mean age 64 years), presenting with a malignant tumour of the anterior base skull, were included. The primary pathology was recurrent squamous carcinoma. Tumour resection resulted in orbital exenteration in 60%, and bone resection of the anterior skull base in 81% of patients. The initial skin defect was 49 cm(2) (range 16-100 cm(2)). The PMMF was the primary reconstructive choice in 87%, and utilized after free flap failure in two cases. Three minor complications were noted. Orbital exenteration and anterior base skull resection is a surgical procedure that leads to significant reconstructive challenges. The PMMF remains a safe and versatile reconstructive tool in anterior skull base tumour resection. The externalized pedicle allows this flap to reach periorbital and anterior skull base.
