Although early complication of airway obstruction following pharyngoplasty is well recognised, there have been few reports of late modifications following this procedure. We retrospectively review cases with late complications which have required either revision or division of an existing pharyngoplasty at the Australian Craniofacial Unit over the last twenty-five years. We assess the outcome of further surgical intervention in each case, with case note and nasendoscopy video review. Fourteen cases were identified where records were complete. There were 12 males and 2 females. The cases are a heterogeneous group of cleft lip and palate patients and include three cases with a diagnosis of Pierre-Robin sequence and one case with a cleft palate as part of an underlying syndrome. Those cases requiring flap division had undergone either superiorly or inferiorly based pharyngeal flaps in contrast to dynamic (Orticochea) pharyngoplasties which required revision. This series of cases demonstrates the need for thorough assessment and planned tailoring of the pharyngoplasty procedure, with ongoing review of speech and airway function. This management philosophy results in the acceptance that a pharyngoplasty may only be required for a limited period of time and ultimately may be redundant.

Apert syndrome is a rare acrocephalosyndactyly syndrome characterised by craniosynostosis, midface hypoplasia and syndactyly of the hands and feet. The majority of cases arise as the result of one of two mutations of the fibroblast growth factor receptor 2 gene (FGFR2). Due to the involvement of both the cranial and the facial sutures, the keystone of the craniofacial skeleton, the sphenoid bone, is affected by the disease process and as a result is dysmorphic. This may significantly affect craniofacial morphology but it is recognised that there are marked variations in this between different affected individuals. This is a retrospective study examining the morphology of the sphenoid bone using three dimensional reconstructions of computed tomography (CT) scan data. Shape analysis was performed using generalised Procrustes analysis and principal component analysis (GPA/PCA). Comparisons were made between the individuals with Apert syndrome and a group of normal individuals, and between the two genotypic groups. The sphenoid bone in those with Apert syndrome showed marked differences in morphology compared to the normal individuals with a restriction in height and increased angulation of the lesser wings; however, there were no consistent differences between the two genotypic groups. It is possible that fronto-orbital advancement (FOA) surgery indirectly releases the sphenoid bone and allows compensatory growth in this direction.

The concept of the cantilever bone graft, popularised by Millard (1966), and its subsequent modification by Chait et al. (1980), led to the idea of the costochondral cantilever graft for nasal dorsum augmentation. Over 150 costochondral nasal grafts have been performed at the Australian Craniofacial Unit (ACFU) over the last 25 years, and the aim of this study was to review a cohort of fractured costochondral graft in patients treated at the ACFU. The notes of patients with nasal costochondral grafts were reviewed, those with a fractured graft forming the basis of this study. Patients with Binder Syndrome accounted for nearly 30% of the cohort. Other diagnoses included Opitz syndrome, frontonasal dysplasia and other craniofacial abnormalities. 3 patients were identified with late fractured costochondral grafts. The prominent position of the nose makes it easily susceptible to trauma, and very often, low energy impact can produce fractures of the nasal bones. To the best of our knowledge, this is the first reported series of fractures of costochondral nasal grafts and their subsequent management. We would advocate early surgical management of the fractured grafts when conservative treatment has failed. In our present series, all 3 patients still maintained a satisfactory cosmetic and functional result after a mean of 8.5 years following the reparative surgery.

The function of a genioplasty is to produce an aesthetically pleasing chin contour and improve facial proportions. The aim of this study was to review the role of osseous genioplasty in the management of patients with craniofacial deformities. 52 patients (24 males and 28 females) treated at the Australian Craniofacial Unit in Adelaide, Australia over a 25-year period; who required a genioplasty as part of their craniofacial management were reviewed. Patients ranged from 17-44 years (median: 26 years) and the age at which the patients underwent genioplasty was between 9 and 36 years (median: 17 years). Pre and 6 months post op cephalograms were compared, showing a mean chin advancement of 7mm and a mean osseous resorption of 20%. One patient was under-corrected and another had post-operative asymmetry, both requiring repeat genioplasty. No long-term nerve dysfunction was noted. The osseous genioplasty is an effective procedure for correcting the chin deformity often seen in patients with craniofacial abnormalities. It is an easy technique to master and is associated with a low degree of morbidity.

The free muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) and deep inferior epigastric perforator (DIEP) flaps involve transferring skin and subcutaneous tissue from the lower abdominal area and have many features that make them well suited for breast reconstruction. The robust blood supply of the free flap reduces the risk of fat necrosis and also enables aggressive shaping of the flap for breast reconstruction to optimize the aesthetic outcome. In addition, the free MS-TRAM flap and DIEP flap require minimal donor-site sacrifice in most cases. With proper patient selection and safe surgical technique, the free MS-TRAM flap and DIEP flap can transfer the lower abdominal skin and subcutaneous tissue to provide an aesthetically pleasing breast reconstruction with minimal donor-site morbidity.

Background: s/Aims: Pancreatic texture is difficult to predict without palpation. Soft pancreatic texture is associated with increased post-operative complications, including postoperative pancreatic fistula (POPF), cardiac, and respiratory complications. We aimed to develop a calculator predicting pancreatic texture using patient factors and to illustrate complications from soft pancreatic texture following pancreaticoduodenectomy. Methods: Data was collected from the 2016 to 2021 American College of Surgeons National Surgical Quality Improvement database including 17,706 pancreaticoduodenectomy cases. Patients were categorized into two cohorts based on pancreatic texture (9,686 hard, 8,020 soft). Multivariable modeling assessed the impact of patient factors on complications, mortality, and pancreatic texture. These preoperative factors were integrated into a risk calculator (preoperative soft pancreas risk score [PSPRS]) that predicts pancreatic texture. Results: Patients with a soft pancreas had higher rates of postoperative complications compared to those with a hard pancreas (56.5% vs 42.2%; p < 0.001), particularly a threefold increase in POPF rate, and at least a twofold increase in rates of acute kidney injury, deep organ space infection, septic shock, and prolonged length of stay. Female sex (odds ratio [OR]: 1.14, confidence interval [CI]: 1.06–1.22, p < 0.001) and higher body mass index (OR: 1.12, CI: 1.09–1.16, p < 0.001) were independently associated with a soft pancreas. PSPRS ≥6 correctly identified >40% of patients preoperatively as having a hard pancreas (68.9% specificity). Conclusions A soft pancreas was independently associated with serious postoperative complications. Our results were integrated into a risk calculator predicting pancreatic texture from preoperative patient factors, potentially enhancing preoperative counseling and surgical decision-making.

OBJECTIVE: Clinicopathological studies over the last decade have broadened the clinical spectrum of progressive supranuclear palsy (PSP) to include several distinct clinical syndromes. We examined the cognitive profiles of patients with PSP-Richardson's syndrome (PSP-RS) and two atypical ‘brainstem predominant' PSP phenotypes (PSP-parkinsonism, PSP-P; and PSP-pure akinesia with gait freezing, PSP-PAGF) using a comprehensive neuropsychological battery. METHODS: Fourteen patients diagnosed as PSP-RS, three patients with PSP-P and four patients with PSP-PAGF were assessed using a comprehensive battery of neuropsychological tests.
