Abstract	Abstract: Bilateral cleft lip deformities makeup 10% of orofacial clefts and are uncommon when compared to unilateral cleft lip.1,2 These cleft deformities have significant physical and long-term psychosocial effects on not only the patient but their family. With bilateral cleft lip deformity, the cutaneous approximation of the lateral lip segments are dependent on a sufficient prolabium to reconstruct the philtrum.3,4 Deficient skin equates to tight midline closure and subsequent unsightly scarringIn the subclinical phenotype of bilateral cleft lip and palate, where the patient has an absent or deficient prolabium, achieving tension free closure in the primary surgical setting is a reconstructive dilemma.5 This clinical report describes the use of a full-thickness skin graft to reconstruct the philtrum in a 12-month-old boy with bilateral cleft lip deformity, absent prolabium, absent columella and absent nasal septum to provide an aesthetic subunit repair.

Abstract	Many pastoral farmers are searching for ways to lower the carbon emission footprint that is generated by livestock. Planting trees on the farm is currently a popular option for farmers to offset their emissions yet requires knowledge of suitable tree species and locations to plant them. This paper describes a decision-support tool aimed at helping farmers to create and visualise different planting designs while balancing the objectives of sequestering carbon and maintaining farm profitability. We take an innovative approach by combining virtual reality technology with biophysical models to create an environment where the user can actively create virtual future farm scenarios. Through the creation process, the user can simultaneously balance multiple objectives including farm aesthetics, economic returns, business and environmental ambitions, and carbon emissions (net) balance. For this proof-of-concept study, we incorporate virtual reality technology in Unreal Engine, environmental and financial data, and high-resolution spatial layers from an operational 400-hectare livestock farm in New Zealand.

Abstract	Lupus erythematous profoundus (LEP) is an uncommon manifestation of chronic lupus erythematous (CLE) involving inflammation of the subcutaneous fat and deep dermis. It is rarely seen in the otolaryngological practice. We describe a case of a 33-year-old female who presented with bilateral acute onset cheek swelling, which led to the unexpected diagnosis of LEP. We describe the diagnostic pitfalls that may potentially bias the surgeon towards the management of such patients.

Abstract	Abstract: Paranasal sinus mucoceles commonly cause erosions of the bony walls. Currently, such defects can be managed conservatively with promising short-term outcomes. Long-term outcomes of these defects have not been described. The authors describe a 28-year-old patient with complete spontaneous osteogenesis of the large dehiscent frontal sinus posterior wall, secondary to a large mucocele, 9 years from functional endoscopic sinus surgery with the defect managed conservatively. Owing to the osteogenic potential of the dura, the authors postulate that the presence of dura beneath the bony deformity of the posterior frontal sinus wall had likely initiated the osteogenesis and restored the defect. This report substantiates studies demonstrating the osteogenic potential of an intact dura. Conservative management is an option for selected large defects of the posterior wall of the frontal sinus.

Abstract	The Asian nose has its unique morphology and forms a significant proportion of noses treated by the rhinoplasty surgeon not only in Asia but also in other countries where the Asian diaspora resides. The anatomical features and dimensions of the Asian nose differ from noses of persons of African, Caucasian, Indian, and Middle Eastern origins, poses its own challenges, and warrants a unique set of techniques for its aesthetic improvement. In this article, we present an overview of the approach to the lengthening of the Asian nose, drawing from our own experience with managing the Asian nose and referencing the published literature on the subject.

Abstract	Background: Current pharmacological management of allergic rhinitis (AR) varies in onset, duration, symptom control, and requires frequent administration. Single-dose botulinum toxin (BTX) has been documented in various trials as a treatment option in rhinitis. Objective: We review the current literature on the use of BTX in rhinitis and investigate the efficacy and safety profile of a novel intranasal injection site for AR control. Study design: Single-arm pilot study. Methods: Ten adult patients having moderate to severe AR with proven house dust-mite allergy were recruited. Each patient received 12.5 units of Botox injected to the posterior lateral wall of each side of the nose under endoscopic guidance. Immediate postprocedural discomfort and Total Nasal Symptom Score (TNSS) at 2 and 4 weeks were used as primary outcome measures. Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) was used as secondary outcome measure. Results: Overall TNSS (minimum = 0; maximum = 20) showed an improvement from a mean of 15.1 (preinjection) to 7.6 (2 weeks) and 7.7 (4 weeks). Greatest effect was seen in subscales of rhinorrhea (4.0-1.7) followed by sneeze, nasal congestion, and itch. Mean discomfort of the procedure was scored 5.7 over 10. RQLQ scores similarly showed an improvement in all domains of quality of life. Two subjects complained of mild headache not requiring any medical intervention. Conclusion: Based on our review of current literature, BTX shows clear efficacy on symptoms of both intrinsic and allergic rhinitis, with a good safety profile. Single-dose posterior nasal injection demonstrates good efficacy and duration of action, with moderate discomfort. Level of evidence: 4. Laryngoscope, 127:2447-2454, 2017.

Abstract	Introduction: Helical rim keloids occur commonly following ear piercings, trauma and previous surgeries and can be disfiguring. Many techniques have been developed to treated these disfiguring lesions with varying successes, however, individuals prone to developing keloids inadvertently recur despite best efforts. Objective: To determine whether helical rim advancement flap reconstruction following helical rim keloid excision can reduce recurrences. Design: Case series followed up to 2 years. Setting: Single Centre Tertiary Hospital Facial Plastics Service. Participants: All patients who consented to helical rim advancement reconstruction after keloid excision. Results: The authors report a series of 7 patients with helical rim keloids ranging from 1.2 cm to 5 cm in widest diameter treated with keloid excision and reconstruction with helical rim advancement flap technique. There were no recurrences within a mean of about 19 months post-operatively. Most patients report satisfaction with the cosmetic end-result. Discussion: From the authors' experience, helical rim advancement reconstruction following excision of keloids about 2.5 cm in widest diameter is an excellent tension-free option to avoid recurrence of helical rim keloids. Wound tension is a key risk factor for keloid formation. We hypothesise that the reason why there was no recurrence is because in helical rim advancement flap reconstruction, the underlying helical rim takes all the tension of closure off the dermis, resulting in tension-free skin closure. Conclusion: Helical rim advancement flap reconstruction is a viable technique to avoid recurrence and minimise cosmetic deformities of the pinna for selected helical rim keloids.

Abstract	Background: Free-tissue transfer flaps are an effective reconstructive option for complex wounds; however, flap failure is a dreaded complication requiring timely re-exploration and salvage. The aim of this study was to determine whether salvage rates were higher in skin flaps, as opposed to muscle flaps, due to the durability of the overlying skin paddle allowing for better visual post-operative monitoring and more timely recognition of the threatened flap. Methods: We conducted a retrospective analysis of all patients who underwent a free flap at an Australian tertiary centre between 2004 and 2014. Data were collected on patient demographics, indication, flap type, time of recognition of the threatened flap and re-exploration outcome. Data were analysed using Stata version 13 (StataCorp, College Station, TX, USA). Student's t-test, analysis of variance and Pearson's chi-squared test were used to compare groups. Results: There were 560 patients who underwent 573 free flaps. The most common indication was trauma. There were 58 re-explorations with a successful salvage rate of 79.3% (46/58). Overall complete flap loss rate was 2.1% (12/573). In flaps requiring re-exploration, there was a higher complete flap loss rate for muscle only flaps versus those with a skin paddle (P-value = 0.041). Conclusion: While timely recognition and re-exploration of the compromised free flap in the early postoperative setting is important in determining the flap salvage success, it is demonstrated that salvage rates are poorer for muscle only flaps compared with flaps with a skin paddle.
