Developing the Optimal Osteotome Hand-Sharpening Method.

Background: Rhinoplasty osteotomes can be sharpened in various ways: professional sharpening or hand sharpening using whetstones or rotary powered devices. Objective: To compare the effectiveness of sharpening osteotomes using various sharpening methods with that of professional sharpening as measured by a custom edge tester. Materials and Methods: We performed repeated serial osteotome impacts on bovine femoral cortical bone. These dull osteotomes were sharpened using preidentified sharpening techniques. Edge morphology was evaluated. Sharpness was tested using a custom mechanical testing platform. Optimized sharpness was achieved with a whetstone sharpening method wherein the osteotome is flipped after every stroke. Results: Seven distinct sharpening methods were tested for sharpness five times each to determine the optimal sharpening method versus professional sharpening (control). The two sharpening methods, 5 (5.51 ± 0.32) and 6 (5.55 ± 0.32), that used this flipping technique were significantly sharper than other methods. Methods 5 (p = 1.0) and 6 (p = 1.0) were the only methods that were not significantly different from control. Conclusion: Single stroke with successively alternating surfaces created the sharpest blades that achieved results similar to professional sharpening.

Navigating trans visibilities, trauma and trust in a new cervical screening clinic.

Trans and gender diverse people are globally recognised as being under-served in clinical services, with significant implications for their health. During a national reorientation of the Australian cervical screening programme - from Papanicolaou smears to human papillomavirus screening - we conducted interviews with 12 key informants in cancer policy, sexual and reproductive health and trans health advocacy to understand how trans people's needs and experiences were being accounted for and addressed in health policy and practice. Themes captured the complexities of increasing visibility for trans people, including men and non-binary people with a cervix. These complexities reflect the extensive system and cultural change required in asking policymakers and practitioners to think differently about who is at risk of a disease typically associated with cisgender women. Informants drew on the language of trauma to explain the resistance many trans people feel when engaging with clinical services, particularly relating to sexual and reproductive health. In doing so, they argued for increasing resources and processes to elicit trans people's willingness to put their trust in such services. Thinking critically about the relationship between the politics of trans visibilities, trauma and trust can support effective and inclusive approaches to transgender health.

Management of the Nasal Valve.

The nasal valve is an important consideration in patients presenting with nasal obstruction. Controversy exists regarding the anatomy, terminology, evaluation, and management of the nasal valve. Innumerable techniques with variable effects have been described in the literature. The evidence qualifying these techniques has been plentiful, though often lacking in quality. This article reviews the controversial aspects of nasal valve management applying the best available evidence to help clarify potential areas of confusion. Future research using standardized definitions, consistent methodologies, and validated outcome measures are necessary to improve the quality of evidence and impact surgical decision-making.

Reconstruction of the naso-orbital-ethmoid (NOE) complex using the osteocutaneous radial forearm flap (OCRFF).

OBJECTIVES: Describe the utility of osteocutaneous forearm flaps in reconstruction of naso-orbito-ethmoid (NOE) defects. STUDY DESIGN: Case series with chart review. SETTING: Tertiary medical centers. SUBJECTS AND METHODS: The study was conducted on patients treated between the years 2000 and 2014 undergoing NOE resection with reconstruction using the radial forearm flap. Decision making, technical feasibility, need for revisions, and patient disease outcomes were included to assess the durability of reconstruction over remaining survival period. RESULTS: Fifteen patients underwent NOE reconstruction in the timeframe studied. Five recent patients reported poor nasal airway but no diplopia or immediately clinically evident enopthalmus after NOE reconstruction in mean follow-up of 17.3 months. One-third of patients succumbed to disease in the study period, 3 without revision, and all but 2 surviving patients required revisions. CONCLUSION: Osteocutaneous radial forearm flap (OCRFF) is a cosmetically acceptable method of reconstructing NOE defects. Though a 1-step reconstruction can be serviceable without multiple additional procedures, longer surviving patients frequently receive revision surgery as with more traditional planned staged procedures.

Complications associated with alloplastic implants in rhinoplasty.

OBJECTIVE: To evaluate the incidence of infection and extrusion of porous high-density polyethylene (pHDPE) and expanded polytetrafluoroethylene (ePTFE) implants used in rhinoplasty at a high-volume, academic facial plastic surgery practice. METHODS: A total of 662 rhinoplasty procedures performed by 3 faculty surgeons from 1999 to 2008 were retrospectively reviewed. Patient demographics, medical comorbidities, operative details, and postoperative course findings were collected from patient records. RESULTS: The incidence of postoperative infection was 2.8% (19 of 662 patients). In each case of infection, alloplastic material had been used. Infections occurred in 1 in 5 rhinoplasty procedures in which pHDPE implants were used. In patients in whom ePTFE was used alone, the infection rate was 5.3%. Exposure developed in 12% of patients in whom an alloplast was used during surgery. Factors notably not associated with infection on bivariate analysis included sex, surgeon, purpose of procedure (functional vs cosmetic), current tobacco use, or history of cocaine use (P > .05 for all). CONCLUSIONS: To our knowledge, this study represents the largest evaluation of the use of pHDPE implants in rhinoplasty to date. Our findings are in contrast to those of previous studies regarding the use of pHDPE in rhinoplasty and parallel to those regarding the use of ePTFE. Caution is strongly recommended when considering the use of pHDPE in rhinoplasty.

Functional genomic analysis unravels a metabolic-inflammatory interplay in adrenoleukodystrophy.

X-linked adrenoleukodystrophy (X-ALD) is an inherited disorder characterized by axonopathy and demyelination in the central nervous system and adrenal insufficiency. Main X-ALD phenotypes are: (i) an adult adrenomyeloneuropathy (AMN) with axonopathy in spinal cords, (ii) cerebral AMN with brain demyelination (cAMN) and (iii) a childhood variant, cALD, characterized by severe cerebral demyelination. Loss of function of the ABCD1 peroxisomal fatty acid transporter and subsequent accumulation of very-long-chain fatty acids (VLCFAs) are the common culprits to all forms of X-ALD, an aberrant microglial activation accounts for the cerebral forms, whereas inflammation allegedly plays no role in AMN. How VLCFA accumulation leads to neurodegeneration and what factors account for the dissimilar clinical outcomes and prognosis of X-ALD variants remain elusive. To gain insights into these questions, we undertook a transcriptomic approach followed by a functional-enrichment analysis in spinal cords of the animal model of AMN, the Abcd1(-) null mice, and in normal-appearing white matter of cAMN and cALD patients. We report that the mouse model shares with cAMN and cALD a common signature comprising dysregulation of oxidative phosphorylation, adipocytokine and insulin signaling pathways, and protein synthesis. Functional validation by quantitative polymerase chain reaction, western blots and assays in spinal cord organotypic cultures confirmed the interplay of these pathways through IkB kinase, being VLCFA in excess a causal, upstream trigger promoting the altered signature. We conclude that X-ALD is, in all its variants, a metabolic/inflammatory syndrome, which may offer new targets in X-ALD therapeutics.

Correction of internal nasal valve stenosis: a single surgeon comparison of butterfly versus traditional spreader grafts.

Nasal obstruction due to internal nasal valve (INV) collapse is relatively common. This article evaluates 2 different methods repairing the INV.Our subject population is a single-surgeon group of 82 patients who underwent a septorhinoplasty for nasal airway obstruction. Patients received either a spreader graft or butterfly graft. There are 30 patients who received spreader grafts and 52 patients who received a butterfly graft. All patients had a minimum of 3 months follow-up. All patients were evaluated with standardized questionnaire. Participants were asked to evaluate improvement in their nasal airway on an analog scale of 1 to 5. Participants were also asked to comment on changes in pre and postoperative snoring and sleep habits. Lastly, participants were queried regarding the ear cartilage harvest and if this bothered them.Patients undergoing both procedures demonstrated an overall improvement in their nasal breathing. Significant differences in improvement were observed for patients in the categories of postoperative snoring, sleep, and continuous positive airway pressure use. Patients were not bothered by the ear cartilage harvest.In select patients, the butterfly graft is a useful solution for INV collapse correction.

The total nasal defect and reconstruction.

The structures of the nose are arguably the most complex within the face to reconstitute when absent. Total nasal reconstruction has evolved to encompass advanced surgical techniques in an effort to achieve increasingly satisfactory cosmetic results while restoring nasal function that mimics the function of a patient's natural nose. In this article, the history of total nasal defects and their reconstruction, relevant nasal anatomy, etiologies of the defect, and the surgical approaches to reconstructing each of the three-layered structure of the nose (ie, nasal skin, cartilage/bone, and lining mucosa) are explored.

Conchal cartilage butterfly graft in primary functional rhinoplasty.

OBJECTIVE: To validate the use of the conchal cartilage butterfly graft in primary functional rhinoplasty and to review our experience using this technique. STUDY DESIGN: A retrospective analysis of patients who underwent conchal cartilage butterfly graft reconstruction of the nasal valve in primary rhinoplasty. METHOD: A retrospective analysis using patient questionnaires was performed. Data were collected to determine patient satisfaction about nasal breathing and cosmesis after the procedure. RESULTS: Among the patients, 90% (n = 90) had improved breathing, 88% (n = 88) were satisfied with their postoperative cosmesis, and 89% said they would recommend the procedure to a friend who had similar preoperative symptoms. CONCLUSION: Conchal cartilage butterfly graft has now been shown to be successful in primary functional rhinoplasty, just as it has previously been proven effective in secondary rhinoplasty. Although we have had success with many techniques for the correction of internal nasal valve collapse, we have found the conchal cartilage butterfly graft to be another outstanding technique for the appropriately selected patient.

Facial resurfacing with coblation technology.

OBJECTIVE: To describe our experience with coblation technology for facial resurfacing METHODS: Retrospective chart review of all patients treated with coblation at our institution RESULTS: Twenty-four patients (22 female) underwent a total of 29 coblation procedures for aging face (n = 21) or acne scarring (n = 3). The perioral region was the most frequently treated aesthetic subunit (n = 14), followed by the lower eyelid (n = 7). Five patients underwent full-face coblation. Three patients underwent a second coblation procedure for aging face while a single patient with severe acne scarring underwent 3 procedures. Repeat coblation was delayed at least 5 months (mean, 9 months). Seventeen coblation procedures (59%) were performed concurrently with procedures including, but not limited to, injection treatment, rhinoplasty, blepharoplasty, or combined face/necklift; no adverse events occurred. Seven procedures, including a full-face coblation, were performed in the office under local anesthesia and oral sedation without any adverse events. Mean follow-up was 6 months (range, 1 week to 24 months). No complications were observed. All patients were satisfied with the results after their final coblation treatment. CONCLUSIONS: Facial coblation is a safe and effective treatment modality for facial resurfacing.

Cigarette smoke extract induced cytokine and chemokine gene expression changes in COPD macrophages.

Macrophages are key inflammatory cells in chronic obstructive pulmonary disease (COPD). The transcriptional regulation of inflammatory signalling pathways by cigarette smoke (CS) in COPD macrophages is not well understood. We have studied the effects of acute CS exposure on COPD macrophage cytokine, chemokine and signal transduction gene expression profiles. Monocyte derived macrophages (MDMs) from whole blood from patients with COPD (n=6) were stimulated with 1%, 10% and 25% CS extract (CSE) for 6h for microarray and quantitative polymerase chain reaction (Q-PCR) analysis. We observed a CSE dose dependant increase in the numbers of significantly regulated genes; 24, 340 and 627 genes at 1%, 10% and 25% CSE, respectively. IL-8 mRNA levels were up-regulated by 10% CSE (2.25-fold increase, 95% CI 1.28-4.00). In contrast a range of other cytokines and chemokines were down-regulated at both 10% and 25% CSE, including IL-1beta, -6, -10 and -18, chemokine ligands CCL-2, -3, -4, -5, -8, -15, -20 and CXCL-1, -2 and -10. Q-PCR and microarray data were highly correlated (r=0.95, p=0.0001). NF-kappaB component p50 and IkappaBalpha expression were suppressed by CSE, while there was up-regulation of the AP-1 components c-Jun, FOSL1 and FOSL2. Acute CSE exposure decreased macrophage inflammatory gene expression, with the exception of increased IL-8. There was diverse regulation of key inflammatory signal pathway genes. The effects of acute CS exposure appear to encompass both up-regulation of chemotaxis mechanisms through IL-8, but also down-regulation of innate immunity.

Direct submentoplasty for neck rejuvenation.

Facial plastic surgeons commonly see patients with submental laxity and an excess of skin and fat in the upper neck. This has colloquially been called the "turkey gobbler" deformity. In some cases, this deformity is the patient's only aesthetic concern, and full face-lift surgery is not desired. In this study, we reviewed the English-language peer-reviewed literature for descriptions of direct excisional submentoplasty techniques. Various designs for skin excision and wound closure have been used by surgeons over the past several decades. This article summarizes the surgical technique as well as the advantages and disadvantages of each method. Furthermore, we propose an approach that incorporates many of the other designs but to our knowledge has not been described previously in the peer-reviewed literature. An understanding of these numerous approaches will better enable facial plastic surgeons to appropriately address and correct patient aesthetic concerns.

The utility of concurrent rhinoplasty and sinus surgery: a 2-team approach.

OBJECTIVE: To evaluate the safety and efficiency of and patient satisfaction with a 2-team approach for combined rhinoplasty and sinus surgery. METHODS: We conducted a retrospective medical chart analysis of consecutive patients with sinus disease and functional nasal obstruction. Forty-four patients (29 women and 15 men; age range, 22-75 years) had severe nasal obstruction with chronic sinusitis and were found to have indications for this procedure. All patients were followed up for a minimum of 6 months after surgery. Patients completed a standardized questionnaire at the time of medical chart review, and 36 patients completed a telephone interview. RESULTS: All 44 patients underwent rhinoplasty with an endoscopic sinus procedure. Twenty-seven procedures (61%) were endonasal, whereas 17 (39%) were open rhinoplasty. Patients with internal nasal valve collapse underwent 28 butterfly grafts, 6 spreader grafts, and 8 batten grafts. The endoscopic sinus procedures consisted of maxillary antrostomy (30/44 [68%]) and ethmoidectomy (28/44 [63%]). Overall, 20 (65%) of 31 patients reported a postsurgical nasal airway that was significantly improved. Most sinus symptoms were resolved postoperatively, with 25 (71%) of 35 patients describing their improvement as significant. Thirty-two (92%) of 36 patients stated that they would recommend the concurrent procedure. CONCLUSION: Patients presenting with nasal obstruction and chronic sinusitis tolerated combined rhinoplasty and sinus procedures without added morbidity.

Reconstructive rhinoplasty: the 3-dimensional nasal tip.

OBJECTIVES: To review nasal alar support mechanisms, introduce the concept of tractional forces on the nasal ala, and describe a reconstructive technique to correct nasal tip deformities associated with weakened tractional force on the nasal ala. DESIGN: Photographic study and retrospective medical chart review. RESULTS: We noted that patients with weakened support at the dome of the lower lateral cartilage had lateral alar deformities. Strengthening the cartilaginous deficiency improved the nasal appearance and function in 90% of patients. CONCLUSIONS: Deformities of the nasal tip are among the most difficult to correct. Tractional forces provided by dome strength help to maintain the ala in its normal anatomical position. Structural tip grafts restore the tractional force and, thereby, help to correct the alar deformity.

The effect on snoring of structural nasal valve dilatation with a butterfly graft.

OBJECTIVE: To evaluate the effect on snoring of structural nasal valve dilatation with butterfly spreader grafts in patients with nasal valve insufficiency. DESIGN: Retrospective medical chart review and telephone follow-up; mean +/- SD follow-up time, 20.7 +/- 11.34 months (range, 3-48 months). SETTINGS: Tertiary care referral center. SUBJECTS: A total of 37 snoring patients with nasal valve insufficiency who underwent nasal valve dilatation with a butterfly spreader graft. INTERVENTIONS: The conchal cartilage butterfly graft technique was performed during rhinoplasty through either an external or endonasal approach. MAIN OUTCOME MEASURE: To establish through a retrospective review that butterfly graft conchal cartilage nasal reconstruction is effective in reducing snoring. RESULTS: After surgery, 30 patients (81%) had significant improvement in breathing, 5 (14%) had slight improvement, and 2 (5%) had no benefit in breathing. Snoring stopped completely in 11 (30%) of the patients after surgery. The improvement in snoring was significant in 13 patients (35%) and slight in 3 (8%). Twenty-six patients (70%) reported tiredness and grogginess on awakening before the surgery. Surgery significantly improved patients' tiredness and grogginess on awakening in 15 cases (58%), slightly improved them in 5 (19%), and did not change the patients' tiredness and grogginess in 6 cases (23%). CONCLUSION: The conchal cartilage butterfly graft yields successful results not only in breathing but also in snoring symptoms in patients with nasal valve insufficiency.

Irradiated homograft rib cartilage in facial reconstruction.

OBJECTIVE: To evaluate long-term structural, functional, and cosmetic results as well as resorption with the use of irradiated homologous rib cartilage grafts (IHRGs). DESIGN: Cases in which IHRGs were used were reviewed for a long-term follow-up study for nasal and auricular reconstruction, dating back 18 years. A retrospective medical chart review was conducted in the cases in which the patients had returned for clinical examination with photographic documentation. RESULTS: A total of 118 patients who had undergone nasal reconstruction with a mean follow-up of 36 months were identified from our database. There were 12 patients who had undergone auricular reconstruction, with a mean follow-up of 82 months. Resorption with compromise in cosmesis was noted in 11% (11/102) of the grafts used in nasal reconstruction but in 71% (5/7) of those used in auricular reconstruction. Minor resorption without change in form or function was found in 29% (30/102) of the cases. Loss of support, which was related more to graft displacement rather than resorption, was identified in 19% (21/109) of the cases, and loss of support affecting cosmesis was observed in 8% (9/109) of the cases. Maintenance of form and function appeared to be unrelated to the amount of resorption noted for the nasal grafts but was significant for the auricular grafts (P < .01). CONCLUSIONS: The longevity of IHRGs has been favorable for functional, structural, and cosmetic nasal reconstruction, with low levels of resorption identified clinically. The use of IHRGs was associated with an unacceptable rate of graft failure in auricular reconstruction; therefore, they are no longer selected for use in such cases.

Self-induced nasal ulceration.

BACKGROUND: Nasal ulcerations have many causes. Ulcerations that are self-induced are difficult to diagnose and treat. Two rare conditions with self-induced nasal ulceration are trigeminal trophic syndrome (TTS) and factitious disorder (FD). Trigeminal trophic syndrome is characterized by trigeminal anesthesia, nasal alar ulceration, and facial paresthesia. Appearance of the nasal ulcer after trigeminal ablation for neuralgia is diagnostic. Self-induced nasal lesions that occur in FD are primarily distinguished from those in TTS by the presence of normal trigeminal nerve function and frequent patient denial of lesion manipulation. OBJECTIVES: To increase physician awareness of the disorders leading to self-induced nasal ulceration and to discuss management issues in our patient series. DESIGN: A retrospective review of 7 cases in which the patients presented for reconstructive consultation between March 1985 and October 1997 and were found to have self-induced nasal ulcerations. SETTING: Tertiary university medical center. RESULTS: Five patients were identified with TTS and underwent nasal reconstruction an average of 43 months (range, 4-72 months) after nasal ulcer presentation. Four of the 5 patients developed ulcer recurrence between 1 and 58 months after reconstruction; secondary reconstruction resulted in recurrence in 2 of these patients. Two patients were identified with FD and self-induced nasal ulceration. One of these 2 patients underwent total nasal reconstruction 15 months after ulcer occurrence and developed recurrence 2 weeks after surgery. CONCLUSIONS: Self-induced nasal ulceration remains a difficult condition to diagnose and treat. Readily treatable conditions should be excluded, and diagnostic workup should include tissue biopsy and laboratory studies. Patients with TTS may have associated ocular findings, and those who do should be referred for ophthalmologic consultation. Surgical reconstruction can be considered in the highly motivated patient with TTS; however, delayed ulcer recurrence is common. Patients with FD should be treated primarily with local wound care and referred for psychiatric intervention. We strongly recommend nasal prosthetic devices as the primary means of aesthetic correction and discourage surgical repair in the patient with FD.

Total nasal reconstruction: utility of the free radial forearm fascial flap.

BACKGROUND: Total nasal defects present daunting challenges to the reconstructive surgeon. The nasal skeleton can be successfully fabricated with bone and cartilage. Reconstruction of the nasal skin with a forehead flap produces an excellent color match for nasal skin. Resurfacing of the internal lining is the most difficult of the 3 layers. Local tissue is often unsatisfactory in amount and/or vascular supply. METHODS: A patient requiring total nasal reconstruction was prospectively examined. Intraoperative technique was recorded, and postoperative function was determined. RESULTS: A paramedian forehead flap was used to resurface the external defect. Split calvarium and conchal cartilage were used to reconstruct the nasal skeleton. A fascial flap harvested from the forearm was used to replace the intranasal lining. Turbinate grafts were placed to line the flap. Postoperative breathing was excellent. CONCLUSIONS: The intranasal portion of a total nasal defect can be successfully reconstructed with a fascial forearm flap. Placement of a turbinate or mucosal graft allows for a thin mucosalized lining with an excellent functional outcome.

Evaluation of pericranial skull adherence during healing in the rabbit model.

BACKGROUND: The endoscopic brow-lift is a popular technique for rejuvenation of the aging brow and forehead. Long-lasting results depend on readherence of the pericranium to the underlying skull in the newly elevated position. Determination of the time required for pericranial readherence to occur is important when considering optimal brow fixation time postoperatively; however, few studies of pericranial healing exist in the literature. OBJECTIVE: To quantify the time required for pericranial adherence after pericranial elevation in a rabbit model. DESIGN: Anesthetized New Zealand white rabbits underwent elevation of a pericranial flap on day 0. The flap was then repositioned and the skin sutured. One unoperated-on group served as a control. A tensiometer was used to measure the force required to separate the pericranial flap from the skull of the control animals and of test animals killed on postoperative days 3, 5, 8, 10, 13, 17, 20, 25, and 28. Statistical analysis was performed to determine the effect of healing time on the strength of pericranial readherence. RESULTS: There was a statistically significant decrease in the force required for pericranial separation at 3 and 5 days after surgery compared with the control group. By 8 days postoperatively and throughout the subsequent times examined, no statistically significant differences from the control group were observed. CONCLUSION: In this rabbit model, pericranial adherence (as measured by tensile strength) is decreased postoperatively and does not return to baseline levels until postoperative day 8.

The 'butterfly' graft in functional secondary rhinoplasty.

OBJECTIVE: To describe a surgical technique (the conchal cartilage "butterfly" graft) which, when used in properly selected patients, has been found to be a dependable method for alleviation of postrhinoplasty internal nasal valve dysfunction. STUDY DESIGN: Retrospective chart review. METHODS: Analysis of consecutive patients with weakness and/or collapse of the upper lateral cartilages following rhinoplasty. Seventy-two patients (37 women and 35 men, age range 17-76 y) had severe nasal obstruction and were found to have indications for this procedure. All patients had undergone at least one rhinoplastic procedure. All patients were followed for a minimum of 2 years after surgery. RESULTS: All 72 patients experienced significant subjective improvement in relative nasal obstruction. Two patients (3%) reported less than total resolution of their difficulty breathing through their nose; the remaining 70 patients (97%) reported complete resolution of their nasal airway problems. No patients reported their postoperative nasal obstruction as the same or worse than their preoperative baseline. Sixty-two patients (86%) reported improvement in the appearance of their nose, 8 patients (11%) felt that their appearance was unchanged, and 2 patients (3%) felt that the appearance of their nose was made worse by the procedure. CONCLUSIONS: Patients presenting with nasal obstruction after rhinoplasty are frequently found to have collapse and/or weakening of their upper lateral cartilages with resulting nasal valve dysfunction. The conchal cartilage "butterfly" graft is a technique which, when properly performed during revision rhinoplasty, yields predictable functional and cosmetic results with minimal morbidity.
