RESUMO

BACKGROUND: The purse-string suture (PSS) is a simple, reversible method for reconstructing skin cancer defects. Its utility may be underappreciated in head and neck reconstructive surgery. OBJECTIVE: To evaluate the utility of the PSS as an adjunct to the reconstructive ladder when reconstructing head and neck skin cancer defects. MATERIALS AND METHODS: This prospective nonrandomized cohort included 109 consecutive adult patients with head and neck defects resulting from skin cancer resection. The PSS was placed in every patient after resection. Patients were evaluated before and after suture placement, and final reconstructive methods were recorded. RESULTS: The PSS resulted in a mean defect area reduction of 77.1% (p < .001) and was used in the final reconstruction in 79 (72.5%) patients. The PSS reduced the number of patients requiring adjacent tissue transfer (11), regional tissue transfer (3), and free tissue transfer (1) by 69.4%, 70%, and 80%, respectively. Fifty patients underwent reconstruction in the operating room. After intraoperative placement of the PSS, it was determined that 22 (44.0%) of these defects could have been reconstructed in the clinic (p = .003). CONCLUSION: The PSS dramatically reduces defect size, simplifies reconstructive techniques, and often permits reconstruction to be performed in the clinic rather than the operating room.

RESUMO

The main purpose of this article is to present an alternative technique for the reconstruction of saddle nose deformity in patients with severely scarred or contracted soft tissue envelopes. In this single surgeon case series, the authors present a two-staged reconstruction performed on four adult patients with saddle nose deformities and contracted soft tissue envelope stemming from a variety of etiologic factors including vasculitis, sarcoidosis, and trauma. Stage one involved placement of a 1 × 4 cm tissue expander along the nasal dorsum through anterior scalp and endonasal incisions. The tissue expander port was positioned under the anterior scalp and injected with saline over 3 weeks in-office. Stage two involved removal of the tissue expander and rhinoplasty using osteocartilaginous rib grafts. All four patients had successful expansion of the contracted soft tissue envelope, creating adequate space for the newly reconstructed nasal framework. One patient developed exposure of the tissue expander through the endonasal incision, which did not lead to any adverse outcome. All patients in this series tolerated expansion well, without complaints of pain or external skin breakdown. The use of soft tissue expanders along the nasal dorsum can successfully expand contracted and scarred soft tissue envelopes prior to reconstructive rhinoplasty. This technique may be an effective alternative to the use of interpolated flaps in treating these patients.

RESUMO

OBJECTIVE: To define and quantify common points and relationships within the anterior nasal septum and recognize the anatomic curvature of the dorsal and caudal septum as arcs with certain rises. STUDY DESIGN: Case series study. METHODS: Forty cadaveric quadrangular cartilages were dissected. Points along the septum were defined and relationships measured. Angles that composed the anterior septum using values that did account for the curvature of the anterior nasal septum, or classical L-strut values, were compared to C-strut values, which included rises away from the L-strut. RESULTS: The mean arc of the nasal septum dorsum was significantly longer than the caudal arc (25.9 ± 5.14 mm vs. 23.96 ± 4.07 mm, P = 0.048); the mean rise of the dorsal arc was significantly shorter than the rise of the caudal arc (3.04 ± 1.25 mm vs. 3.88 ± 1.42 mm, P = 0.006). The mean point of furthest rise of the dorsal arc was slightly anterior to the midpoint of the dorsal strut (13.43 ± 5.07 mm); the mean caudal equivalent was slightly posterior to the midpoint of the caudal strut (8.55 ± 4.33 mm). Septal angles measured using L-strut versus C-strut values were significantly different. CONCLUSION: The L-strut leading edge is not congruent with the anatomic septum and can be better described as a C-strut with arcs and rises away from classically interpreted straight L-strut lines, all of which may guide surgeons in the creation of a more natural, supportive cartilage framework while encouraging quantifiable septorhinoplasty teaching.

RESUMO

IMPORTANCE: Wound healing influences both the cosmetic and functional outcomes of facial surgery. Study of cutaneous innervation may afford insight into patients' preoperative wound healing potential and aid in their selection of appropriate surgical procedures. OBJECTIVE: To present the quantitative and qualitative differences of epidermal nerve fibers (ENFs), neurotransmitters, vasculature, and mast cells in facial skin among patients after primary and revision rhytidectomies. DESIGN, SETTING, AND PARTICIPANTS: This pilot study collected cutaneous specimens from 8 female patients aged 42 to 66 years who underwent primary rhytidectomy (n = 5) and revision rhytidectomy (n = 3) at Centennial Lakes Surgery Center, Edina, Minnesota, from July 2010 to March 2014. Tissue was processed for confocal/epifluorescence microscopy and indirect immunofluorescent localization of several neural and tissue antigens as well as basement membrane and mast cell markers. INTERVENTION: Primary rhytidectomy vs revision rhytidectomy with selection of a small area of redundant, otherwise disposed of tissue anterior to the tragus for ENF study. MAIN OUTCOMES AND MEASURES: Demographic characteristics included smoking status; 10-point rating scales for facial sensation, pain, and paresthesias; and confocal/epifluorescence microscopy to quantify ENFs, neurotransmitters, vasculature, and mast cells. RESULTS: Patients in the primary rhytidectomy group had a mean (SD) of 54.4 (31.6) ENFs/mm (range, 14.2-99.2 ENFs/mm), and those in the revision rhytidectomy group had a mean (SD) of 18.6 (5.8) ENFs/mm (range, 13.8-25.0 ENFs/mm). A patient in the primary rhytidectomy group was a 25-pack-year smoker and had 14.2 ENFs/mm, the lowest in both groups. In addition to these structural neural changes, functional neural changes in revision rhytidectomy samples included qualitative changes in normal neural antigen prevalence (substance P, calcitonin gene-related peptide, and vasoactive intestinal peptide). Capillary loops appeared less robust and were less common in dermal papilla among samples from both the primary and revision groups, and mast cells were more degranulated. No differences were found in subjective, self-reported postoperative facial sensation. CONCLUSIONS AND RELEVANCE: Previous skin elevation was associated with decreased epidermal nerve fiber density and qualitative changes in dermal nerves, capillaries, and mast cells in a clinical sample of patients undergoing rhytidectomy. Future research is needed to determine whether histological findings predict wound healing and to better understand the effects of surgery on regenerative capacity of epidermal nerve fibers. LEVEL OF EVIDENCE: NA.

RESUMO

OBJECTIVES/HYPOTHESIS: Third-party payors have begun to demand imaging studies to document septal deviation prior to authorizing septoplasties. This study aims to determine whether septal deviation findings on computed tomography (CT) correlate with symptoms of nasal obstruction as determined by the Nasal Obstruction Symptom Evaluation (NOSE) scale. STUDY DESIGN: Prospective and retrospective chart review. METHODS: Patients 18 years or older undergoing CT scans, which included the nasal septum, were asked to complete a NOSE scale survey and report the laterality of any possible obstruction. Coronal CT images of subjects were graded by two blinded otolaryngologists and two blinded neuroradiologists using a grading system devised by the authors. RESULTS: Seventy-three subjects met inclusion/exclusion criteria. Interobserver reliability about the degree of septal deviation on CT scans was moderately good to substantial (κ values, 0.43 to 0.72). There was poor correlation between NOSE scores and degree of deviation on CT scans (Kendall's τ, 0.031 to 0.045; P values all >.05). There was poor concordance between the side of symptoms that patients reported and the side that observers thought was most deviated on CT. CONCLUSIONS: There is little correlation between septal deviation findings on CT scans and symptoms of nasal obstruction. The results do not support a role for CT scans as either a clinically meaningful or necessary test to investigate uncomplicated nasal obstruction. LEVEL OF EVIDENCE: 4.

RESUMO

OBJECTIVES/HYPOTHESIS: To evaluate the management and outcomes of children with invasive fungal sinonasal disease treated with radical surgery. STUDY DESIGN: Retrospective case series. METHODS: From 1994 to 2007, 11 pediatric patients were identified with invasive fungal sinonasal disease treated surgically by the same pediatric otolaryngologist. Collected data included demographics, oncologic diagnoses, absolute neutrophil counts, symptoms, computed tomography scan findings, biopsy and culture results, surgical procedures, concurrent medical therapies, complications, and survival. RESULTS: The studied patient population consisted of four males and seven females with an average age of 10 years (range, 2-14 years). Six patients were diagnosed with acute lymphoblastic leukemia and five with acute myeloid leukemia, which included 10 cases of relapsed disease. The average number of severely neutropenic days prior to diagnosis of an invasive fungal infection was 18 (range, 8-41 days). Culture results demonstrated Alternaria in seven patients and Aspergillus in four. Nine patients underwent an external medial maxillectomy, five of which were bilateral, and six underwent septectomy. All 11 patients (100%) were cured of their invasive fungal sinonasal disease without relapse. Three patients eventually died from unrelated causes. CONCLUSIONS: Invasive fungal sinonasal disease is a life-threatening problem in immunocompromised children, especially with relapsed leukemia. Successful treatment depends on timely and aggressive surgical, antifungal, and supportive therapies. To our knowledge, this study represents the largest series of pediatric patients with invasive fungal sinonasal disease managed via an aggressive surgical approach with the best outcomes to date. LEVEL OF EVIDENCE: 4.

RESUMO

Posttraumatic soft-tissue injuries of the face are often the most lasting sequelae of facial trauma. The disfigurement of posttraumatic scarring lies in both their physical deformity and psychosocial ramifications. This review outlines a variety of techniques to improve facial scars and limit their lasting effects.

RESUMO

Ear mold impression middle ear foreign bodies are a rare complication of hearing aid fitting. Only a small number of cases have been reported; however, the actual incidence is unknown and likely much higher than expected. We present the case of a 77-year-old man with a history of preexisting tympanic membrane perforations who presented with an ear mold impression middle ear foreign body that required surgical removal. We explore the state and federal laws that guide the interaction between patients, hearing aid sellers and otolaryngologists. We highlight steps that can be taken to reduce the incidence of this complication.

RESUMO

Nasal fractures are usually diagnosed by clinical examination, with or without the support of imaging studies. While plain-film radiography lacks sensitivity and specificity for diagnosing nasal fractures, and computed tomography (CT) is not always practical or cost-effective, ultrasonography (US) may be useful in this regard. The criteria by which adult nasal fractures are reliably identified on US must be clear. We conducted a preliminary prospective, controlled, observational study to define the appearance of nasal fractures on US. We used US to image 12 patients with a clinical or radiologic (CT or x-ray) diagnosis of nasal fracture. All patients presented within 2 weeks of their injury. For comparison purposes, we also obtained US images from 12 control subjects who had no history of nasal trauma or surgery. We found that we could confidently diagnose nasal fractures on lateral-view US on the basis of a disruption of bone continuity and/or displacement of fracture segments. However, our findings were not as consistent with dorsal-view US, and we do not believe it is adequate for diagnosis. We conclude that lateral US can be used to detect nasal fractures in adults, but further studies are needed to assess its sensitivity, specificity, cost-effectiveness, and practicality.

RESUMO

OBJECTIVES: To evaluate clinical and immunohistopathological effects of topical glycyl-histidyl-lysine-copper (GHK-Cu) on in vivo irradiated rat wounds. DESIGN: Animal model. SETTING: Academic institution. SUBJECTS AND METHODS: After dorsal irradiation and a 28-day recovery period, 2 × 8 cm cranially based dorsal flaps were created in Sprague-Dawley rats. Twice daily GHK-Cu gel (test) or aquaphilic ointment (control) was applied for 10 days. Animals were euthanized, digital images of flaps were taken, and harvested tissues were immunohistochemically stained for a vascular endothelium marker, caveolin-1, and vascular endothelial growth factor (VEGF). Digital image analysis was used for outcome measures. Unpaired t-tests were used for statistical analyses; significance of P < .01 accounted for multiple comparisons. RESULTS: By digital analysis of clinical images, 13 test and 10 control animals showed mean ischemic areas of 5.0 cm(2) (SD = 0.9) for tests and 3.8 cm(2) (SD = 1.1; P = .011) for controls. Whole slide digitized images allowed quantification of caveolin-1-stained blood vessels and VEGF expression in fibroblasts at the interface of healing flaps. Caveolin-1 analyses showed a mean of 209.0 vessels (SD = 111.1) and a mean vessel luminal area of 525.7 um(2) (SD = 191.0) in tests and 207.4 vessels (SD = 109.4; P = .973) and 422.8 um(2) (SD = 109.7; P = .118) in controls. VEGF quantified as the percentage of pixels exceeding a colorimetric threshold, with higher fractions of positive pixels indicating more intense staining, showed a mean intensity score of 0.34 (SD = 0.19) in tests and 0.54 (SD = 0.41; P = .169) in controls. CONCLUSIONS: Irradiated dorsal rat flaps treated with topical GHK-Cu gel demonstrated no difference in flap ischemia, blood vessel number or area, or VEGF expression compared to controls.

RESUMO

Background. To report on the use and feasibility of a multimodality approach using concomitant radiotherapy and chemotherapy in patients with high-risk nonmelanoma skin carcinoma (NMSC) of the head and neck. Methods. Records of patients with NMSC of the head and neck who received concomitant CRT at the University of North Carolina between 2001 and 2007 were reviewed. Results. Fifteen identified patients had at least one of the following high-risk factors: T4 disease (93%), unresectability (60%), regional nodal involvement (40%), and/or recurrence (47%). Ten patients were treated in the definitive setting and five in the postoperative setting. Platinum based chemotherapy was given in 14 (93%) patients. Ten of fifteen (67%) patients completed all planned chemotherapy treatments, and thirteen patients (87%) completed at least 80% of planned chemotherapy. Mild radiation dermatitis occurred in all patients and reached grade 3 in 13% of patients. No patients experienced grade 4 or 5 toxicity. With a median followup of 31 months in surviving patients, the 2-year actuarial locoregional control and relapse-free survival were 79% and 49%, respectively. Conclusions. Definitive or postoperative chemoradiotherapy for patients with locally advanced or regionally metastasized NMSC of the head and neck appears feasible with acceptable toxicities and favorable locoregional control.

RESUMO

Infantile myofibromatosis is a rare proliferative mesenchymal disorder that has a potential for rapid growth and recurrence. Approximately 30% of infantile myofibromatosis lesions present in the head and neck, and some of these can cause significant morbidity. We report a case of recurrent infantile myofibromatosis that persisted after surgery and chemotherapy and was managed conservatively. Treatment of infantile myofibromatosis varies according to the size, location, and extent of disease. Solitary lesions may be simply observed in view of their potential for regression, but surgical excision, radiotherapy, and/or chemotherapy should be considered on a case-by-case basis, especially for nonresectable, rapidly progressive, or symptomatic lesions.

RESUMO

BACKGROUND: Activated mast cells (MC) present in the myocardium of patients with cardiomyopathy may contribute to left ventricular dilatation and systolic dysfunction. We sought to determine whether peripheral levels of tryptase, an MC-specific protease, are related to indices of left ventricular size and function, as well as congestive heart failure (CHF) or coronary artery disease (CAD). METHODS AND RESULTS: Serum tryptase was measured in 85 patients undergoing cardiac catheterization with left ventriculography and coronary angiography and examined in relation to left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), congestive heart failure (CHF), and angiographically evident CAD. Systemic tryptase levels were lower in patients with increased (>90 mL) LVEDV (6.2 [5.3-8.0] mcg/L versus 8.3 [6.6-10.3] mcg/L, P=.01) and in patients with CHF (6.2 [3.6-7.3] mcg/L versus 8 [6.2-10] mcg/L, P=.02) and tended to be lower in patients with depressed (<55%) LVEF (6.8 [5.2-9] mcg/L versus 8 [6.3-9.9] mcg/L, P=NS). Linear regression did not show a significant relationship between tryptase levels with either LVEF or LVEDV. Finally, tryptase levels were consistently elevated in relation to the presence of CAD. CONCLUSION: Despite increased numbers of MC in the myocardium of patients with cardiomyopathy, systemic levels of MC tryptase appear to be lower in relation to LV systolic dysfunction, LV dilatation, or clinical CHF. In contrast, the presence of angiographically significant CAD is associated with elevated systemic tryptase levels.

RESUMO

Both acute coronary occlusion and reperfusion of an infarct-related artery lead to significant myocardial cell death. Recent evidence has been presented that activation of the transcription factor nuclear factor-kappaB (NF-kappaB) plays a critical role in reperfusion injury. NF-kappaB is usually bound to its inhibitor, IkappaB, and classic activation of NF-kappaB occurs when the 20S proteasome degrades IkappaB that has been phosphorylated and ubiquitinated. In this study, activation of NF-kappaB was inhibited by systemic administration of a 20S proteasome inhibitor (PS-519) in a porcine model of myocardial reperfusion injury. The experimental protocol induced myocardial ischemia in the distribution of the left anterior descending coronary artery for 1 h with subsequent reperfusion for 3 h. A single systemic treatment with PS-519 reduced 20S proteasome activity; blocked activation of NF-kappaB induced by reperfusion; reduced creatine kinase, creatine kinase-muscle-brain fraction, and troponin I release from the myocardium; preserved regional myocardial function measured by segmental shortening; significantly reduced the size of myocardial infarction; and exhibited no acute toxicity. These data show that myocardial reperfusion injury can be inhibited by using proteasome inhibitors, which likely function through the inhibition of NF-kappaB activation.
