RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

PURPOSE: Various types of the harmonic scalpel blades have been used for tonsillectomy since the early 2000s with varying successes. The HARMONIC ACE® + 23 cm shears is a relatively new blade which has not been studied in an adult population yet. METHODOLOGY: A randomized controlled pilot study was performed comparing the HARMONIC ACE® + 23 cm shears (HS) and monopolar electrocautery (EC) tonsillectomy in 20 patients. Intraoperative blood loss, pain control, return to normal diet and activity as well as patient satisfaction outcomes were compared between these two arms. RESULTS: The operative time was comparable. Compared to the EC arm, there was less intraoperative bleeding, lower risks of delayed haemorrhage and readmission in the HS arm. Post-operative pain scores and use of analgesia were similar. There was earlier return to normal diet and activity in the HS arm compared to the EC arm. More patients in the HS arm recommended using HARMONIC ACE® + 23 cm shears compared to those in the EC arm. This is a non-inferiority study which suggests that the HARMONIC ACE® + 23 cm shears is comparable to monopolar electrocautery in terms of efficacy and post-operative complication rates with better patient satisfaction outcomes. The main weakness of the study is a small study population. CONCLUSION: This is the first reported study comparing the use of the HARMONIC ACE® + 23 cm shears with monopolar cautery in tonsillectomy. A prospective adequately powered study validated by objective outcome measures would be useful to verify the findings from this pilot study.

RESUMO

OBJECTIVE: To evaluate the efficacy and compare postoperative pain and recovery following PEAK PlasmaBlade and monopolar electrocautery tonsillectomy in adults. STUDY DESIGN: Prospective double-blinded randomized controlled trial. METHODS: Fifty-eight patients were recruited and randomized into 2 groups: PEAK PlasmaBlade (n = 29) or monopolar electrocautery (n = 29) tonsillectomy. Postoperative pain, complications, patient satisfaction, number of tablets of analgesia taken and days taken to return to soft diet, normal diet, normal activities and achieve pain-free swallowing were compared and analysed, with the aid of a pain diary given to patients. Statistical analysis was performed with SPSS 13.0 with statistical significance set at P < 0.05. RESULTS: Patients in the PEAK PlasmaBlade group were able to achieve pain-free swallowing in a shorter time compared to the electrocautery group (13.28 versus 15.76 days, P = 0.035). Patients were also more satisfied with PEAK PlasmaBlade tonsillectomy (P = 0.046). No significant differences in the incidence of postoperative haemorrhage, daily visual analog score for pain, number of tablets of analgesia taken and time taken to return to soft diet, normal diet and activities were seen for both groups. CONCLUSIONS: This study showed that PEAK PlasmaBlade tonsillectomy has a faster recovery period in terms of time taken to achieve pain-free swallowing and may offer advantages when compared to monopolar electrocautery tonsillectomy. LEVEL OF EVIDENCE: 1b.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Our case report describes a young male mechanic who was hit in his face by a spring while repairing a car, resulting in traumatic injury to the frontal sinus, with fractures of both the anterior and the posterior tables with dural defect and cerebrospinal fluid leak. Current guidelines recommend that comminuted and/or displaced fractures of the posterior table of the frontal sinus with dural defects should be either cranialized or obliterated. In this patient, instead of cranializing or obliterating the frontal sinus, we managed to preserve the frontal sinus anatomy and its outflow tract using a combined open bicoronal and nasoendoscopic approach. This avoids the long-term complications associated with cranialization or obliteration including mucocele formation and frontocutaneous fistula.

RESUMO

INTRODUCTION: Traction orthoses are thought to optimize recovery from intra-articular finger fractures by restoring joint space and allowing early motion. Evidence to date has, however, consisted only of case series. PURPOSE OF THE STUDY: To compare swing traction versus no-traction management of complex fractures of proximal inter-phalangeal (PIP) finger joints. We hypothesized that there is no long-term (i.e. >12 month) difference between swing traction and no-traction (with or without surgical fixation) in terms of motion, pain, function, patient satisfaction, or treatment cost. METHODS: Adults with a history of complex PIP fractures affecting ≥30% of articular surface injury were identified from database searches at three public hospitals and a private clinic and invited to participate. X-rays taken at the time of injury were graded by two blinded assessors, and participants attended a clinic for measurement of range of motion (ROM) and self-reported function, pain, and satisfaction at least one year post injury. Participant data were then were grouped by treatment provided. One group (N = 17) was treated with swing traction and the other group (N = 14) had no-traction. The primary outcome was combined motion of the PIP and distal inter-phalangeal (DIP) joints, expressed as both total active motion and Strickland score. Secondary outcomes were physical function and symptoms as measured by the Disabilities of Arm, Shoulder and Hand (DASH), patient satisfaction, pain, complication rates, and cost of treatment, based on mean resource consumption per group. RESULTS: Patients treated with swing traction had greater finger motion than those in the no-traction group, which was statistically and clinically significant. There were no differences in patient ratings of function, pain or satisfaction. Complications, such as swan-neck deformity, cold sensitivity, malunion, infection, or adhesions occurred in over half of both groups of participants. During the treatment phase, the swing traction group attended hand therapy an average of 13.3 times, and the no-traction group attended 11.7 times. Average costs for swing traction were less than for surgical fixation with no-traction. DISCUSSION: The significantly different range of motion found in our study did not translate to better DASH scores. The DASH is designed to measure global upper limb physical functioning and symptoms, but lacks sensitivity in populations with finger injuries. CONCLUSIONS: Patients treated with the swing traction protocol had greater range of motion in the finger, however this did not translate to improved patient ratings of function, pain or satisfaction. A basic cost comparison indicated that swing traction may be less expensive than other forms of surgical repair. LEVEL OF EVIDENCE: 3.

RESUMO

We present 3 patients who complained of distorted hearing, tinnitus and otalgia resulting from scalp and facial hair impacting against the tympanic membrane. Removal of the migrated hair with microsuction relieved symptoms immediately. In 2 cases, the patients had presented to the primary care physician earlier, shortly after a haircut. The family physicians had correctly detected the migrated hair but failed to identify this as the cause of the patient's symptoms. Increased awareness of this potentially common complication will enable the family physician to identify and treat these patients in a primary care setting.

RESUMO

OBJECTIVE: The objective of this study is to evaluate the efficacy of tonsillectomy in reduction of respiratory disturbance index (RDI) and other sleep study parameters in patients with obstructive sleep apnea (OSA). METHODS: This study involves 34 adults with OSA and Friedman grade 3 or 4 tonsils. All 34 patients were treated with tonsillectomy, as the only surgical treatment for OSA from 2007 to 2011. Pre- and postoperative polysomnography were performed in all these patients. RESULTS: Prior to tonsillectomy, 21 patients had severe, 9 had moderate, and 4 had mild OSA. Surgical response rate (defined as 50% or more reduction in apnea-hypopnea index (AHI) and a postoperative AHI of less than 20) was 71.4% among patients with severe OSA, 77.7% among patients with moderate, and 75% among patients with mild. Among all the 34 patients, there was a reduction of 24.6 (p = 0.000) in the RDI postoperatively. In our sub-analysis, we arbitrarily divided the patients into three groups: patients with RDI less than 30, patients with RDI between 30 and 60, and patients with RDI above 60. It showed that, in the group with RDI >60, an average reduction of RDI by 57.6 (p = 0.000) was achieved and was the greatest reduction in RDI. CONCLUSIONS: Tonsillectomy alone may be considered as an effective first line surgical procedure in the treatment of OSA in selected patients. Patients with Friedman grade 3 or 4 tonsils may be considered for tonsillectomy as the initial surgical procedure, reserving other upper airway procedures at a later stage if necessary.
