Objectives/Hypothesis: Free flap transfer offers a versatile option for reconstruction in head and neck surgery, with success rates over 95%. There remains a substantial re-exploration rate of roughly 5% to 15%, with early recognition of compromise essential to flap survival. Monitoring techniques are highly desirable, with the gold standard being clinical monitoring. The Cook-Swartz Doppler (CSD) probe utilizes Doppler technology to inform clinicians about real-time flow. We aim to describe our adoption of this technology in 100 consecutive free flaps.Study Design: Prospective case series. Methods: Prospective data were collected from July 2014 to June 2015 on 100 consecutive free flaps performed at a head and neck unit in London, Ontario. All patients had a CSD inserted for arterial and venous monitoring.Results: A total of 100 free flaps were performed on 99 patients. Sensitivity was 87.1% and specificity was 85.7%. Positive predictive value was 98.8% and negative predictive value was 33.3%. False-negative and false-positive rate were 1.0% and 12.0%, respectively. The exploration rate was 12%, with no flap loss and two partial debridements. The CSD was helpful in management in 9% of cases and was clinically unhelpful in 11% of cases, with 10 of 11 abnormal signals ignored. There were three unique CSD complications; one retained wire, one pedicle laceration during extraction, and one clot around the probe interrupting signal.Conclusions: The CSD is a helpful adjunct to clinical monitoring but has unique complications, which were not previously described. Pros and cons must be considered for new centers adopting this technology.

Background: The Sydney Facial Nerve Clinic (SFNC) is a multidisciplinary clinic established in 2015, consisting of surgeons (otolaryngologists, head and neck and plastics/ reconstructive), physiotherapists and speech pathologists. Methods: We reviewed patients who attended the SFNC in the first 3 years and who had their symptoms recorded using the Facial Disability Index, and clinical staging recorded utilising the House-Brackmann (HB) score, Sydney Facial Nerve Score and Sunnybrook Facial Grading System (SFGS). Results: Between May 2015 and June 2018, 145 patients attended the clinic. Mean age was 44.6 AE 17.3 years with 94 (64.8%) females. Most referrals came from general practitioners (n = 75, 54.5%). The most common aetiology was iatrogenic injury (n = 55, 37.9%), followed by Bell's palsy (n = 48, 33.1%), congenital (n = 11, 7.6%), herpes zoster oticus (n = 9, 6.2%), trauma (n = 9, 6.2%) and other (n = 13, 9.0%). The median HB was 4, the mean Sydney score 7.3/15 and the mean SFGS was 45/100. Patients with iatrogenic causes had the worse facial nerve scoring in HB, Sydney and SFGS. Patients with congenital aetiology reported the least symptoms on Facial Disability Index (P < 0.001). Most patients were recommended non-surgical management (n = 92, 64.3%); 51 (35.7%) were referred for botulinum toxin + facial physiotherapy, 25 (17.2%) for physiotherapy alone, seven (4.9%) for botulinum toxin alone and nine (6.3%) for conservative management. Fifty-one patients (35.7%) were recommended surgery, generating 75 procedures; 24 oculoprotective, 22 static, 12 gracilis transfers, 10 temporalis myoplasties and seven nerve transfers. Conclusion: Iatrogenic injuries are the most common presentation for this clinic and have a more severe clinical presentation. Most patients presenting to the SFNC were managed non-surgically.© 2020 Royal Australasian College of Surgeons ANZ J Surg 90 (2020) 856-860ANZJSurg.com

Objectives: Needle electromyography (EMG) may be used to characterise the severity of the injury in acute peripheral facial nerve palsy (FNP) to predict recovery and guide management, but its prognostic value and clinical utility remain controversial.The aim of this systematic review was to evaluate the role of EMG to prognosticate the recovery of facial motor function in patients with acute peripheral FNP. Design: A comprehensive search strategy was applied in PubMed, Embase, and Web of Science based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The main outcome measure was the accuracy of EMG in predicting long-term facial function at least 6 months following symptom onset.Results: Eleven studies were included comprising 3837 participants, with 91.6% of these diagnosed with Bell's palsy (BP). In BP patients, the positive predictive value and negative predictive value for a good outcome based on EMG findings ranged from 82.1% to 100% and 66.7% to 80.5%, respectively, with two out of three studies finding that EMG remained a significant predictor of the outcome on multivariate analysis. Three studies addressed the role of EMG in non-idiopathic FNP with two of these studies supporting EMG to predict prognosis.Conclusions: EMG is a useful tool to gain insight into the likely outcome to guide management decisions and counsel patients on their expectations, particularly in BP. However, given inconsistencies in its application and lack of evidence around nonidiopathic FNP, it should not currently be relied on to predict recovery. Ultimately, its prognostic value and widespread adoption are dependent on the implementation of a clear and standardised protocol in future high-quality studies and routine clinical settings.

Objectives Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) has enabled better prognosis for patients with peritoneal surface malignancies. However, in older age groups, short -and long-term outcomes are still perceived as poor. We evaluated patients aged 70 and over and determine if age is a predictor of morbidity, mortality and overall survival (OS). Methods A retrospective cohort analysis was performed on CRS/HIPEC patients and categorised by age. The primary outcome was overall survival. Secondary outcomes included morbidity, mortality, hospital and incentive care unit (ICU) stay and early postoperative intraperitoneal chemotherapy (EPIC). Results A total of 1,129 patients were identified with 134 aged 70+ and 935 under 70. There was no difference in OS (p=0.175) or major morbidity (p=0.051). Advanced age was associated with higher mortality (4.48 vs. 1.11 %, p=0.010), longer ICU stay (p<0.001) and longer hospitalisation (p<0.001). The older group was less likely to achieve complete cytoreduction (61.2 vs. 73 %, p=0.004) and receive EPIC (23.9 vs. 32.7 %, p=0.040). Conclusions In patients undergoing CRS/HIPEC, age of 70 and above does not impact OS or major morbidity but is associated with increased mortality. Age alone should not be a limiting factor in selecting CRS/HIPEC patients. Careful multi-disciplinary approach is needed when considering those of advanced age.
