RESUMO

BACKGROUND: A change in nasal tip rotation is a very common maneuver performed during rhinoplasty. Among the many techniques used to achieve this goal is the tongue-in-groove (TIG). OBJECTIVES: This study addresses the long-term effect of the TIG on the nasal tip rotation 1 year after rhinoplasty. METHODS: The authors prospectively identified patients who were submitted to a rhinoplasty with a TIG maneuver over a period of 1 year. The angle of rotation was measured along the nostril axis angle. The data were analyzed using the t test and a linear regression model. RESULTS: Seventeen patients were included. The average preoperative tip rotation was 93.95° (SD, 3.12°). Immediate postoperative tip rotation averaged 114.47° (SD, 3.79°). At the 1-year follow-up appointment, the tip rotation averaged 106.55° (SD, 3.54°). There was a significant loss of rotation at the 1-year postoperative visit (P < 0.0001), with an average loss of 7.9° (SD, 3.25°), which amounted to 6.8%. The preoperative rotation didn't affect the amount of loss of rotation (P = 0.04). It can be estimated that, for every degree of rotation that is changed at surgery, the tip can be expected to lose 0.35 degrees over the first year. CONCLUSIONS: TIG is a more dependable technique than the ones that rely on healing and contraction to obtain rotation. Our data demonstrated a significant loss of rotation during the first year. This suggests that the surgeon needs to slightly overcorrect the tip rotation to account for this loss.

RESUMO

Sound surgical technique is necessary to achieve excellent surgical outcomes. Despite the fact that dermatologists perform more office-based cutaneous surgery than any other specialty, few dermatologists have opportunities for practical instruction to improve surgical technique after residency and fellowship. This 2-part continuing medical education article will address key principles of surgical technique at each step of cutaneous reconstruction. Part I reviews incising, excising, and undermining. Objective quality control questions are proposed to provide a framework for self-assessment and continuous quality improvement.

RESUMO

When examining the results of this technique, improvement is noticed in the infraorbital hollowing, midface tissue ptosis, depth of nasolabial folds, and degree of jowling. The greatest overall improvement is the extent of midface ptosis and infraorbital hollowing at the lower eyelid-cheek junction followed by improvement in the nasolabial region. Improvement in jowling was common but less significant than the improvement of the midface structures. The authors think that this dramatic improvement is owing to multiple factors. With wide and complete release of the central and lateral midfacial structures, the en bloc suspension of the SOOF and malar fat pad is thoroughly accomplished. Unlike other midfacial techniques, the transtemporal midface achieves pull in 2 vectors, directing the repositioning of tissuesboth superiorly and laterally. The superior vector repositions the SOOF and malar fat pad over the bony infraorbital rim and malar/zygomatic complex, whereas the lateral pull effaces the nasolabialfold. This superior vector more accurately reverses the forces of aging displayed on the ptotic midface. Lastly, although this technique is not designed primarily to eliminate jowling at the mandible, it has been noted that elevation of 1.0 to 1.5 cm of skin overlying the mandible is typical. Although the endoscopic forehead midface lift is not without its complications or pitfalls, all of these can be minimized, easily managed, or avoided completely through the intraoperative techniques and postoperative care. Careful and deliberate preoperative counseling of patients regarding the possible bumps in the road to recovery is critical. By using the techniques available to limit and manage complications and setting appropriate patient expectations should these complications occur, the endoscopic forehead midface lift can become an extremely powerful and safe technique in the facial cosmetic surgeon's armamentarium to efface the lid-cheek junction with a high degree of patient satisfaction.

RESUMO

Over the past two decades the use of endoscopes for facial rejuvenation gained wide popularity due to its reliable and reproducible results and limitation of the morbidity related to the open approaches. A thorough knowledge of the anatomy is of paramount importance to safely release all the fascial attachments while avoiding injuries to the facial nerve. The authors find the endoscopic forehead midface lift to be a reliable and safe procedure for facial rejuvenation.

RESUMO

Traumatic brain injury (TBI) afflicts up to 2 million people annually in the United States and is the primary cause of death and disability in young adults and children. Previous TBI studies have focused predominantly on the morphological, biochemical, and functional alterations of gray matter structures, such as the hippocampus. However, little attention has been given to the brain ventricular system, despite the fact that altered ventricular function is known to occur in brain pathologies. In the present study, we investigated anatomical and functional alterations to mouse ventricular cilia that result from mild TBI. We demonstrate that TBI causes a dramatic decrease in cilia. Further, using a particle tracking technique, we demonstrate that cerebrospinal fluid flow is diminished, thus potentially negatively affecting waste and nutrient exchange. Interestingly, injury-induced ventricular system pathology resolves completely by 30 days after injury as ependymal cell ciliogenesis restores cilia density to uninjured levels in the affected lateral ventricle.

RESUMO

OBJECTIVE: To evaluate changes in the expression of biofilm-related genes when exposed to tobacco smoke and oxidative stress. STUDY DESIGN: Experimental, in vitro. Setting Laboratories of Rhinology and Microbiology, University of Pennsylvania. SUBJECTS AND METHODS: Bacterial biofilm mass was measured using crystal violet staining and measurement of the optical density. Biofilm-related genes of the Pseudomonas aeruginosa PAO1 strain (pilF, flgK, lasI, lasB, rhlA, and algC) were studied following repetitive exposure to exogenous tobacco smoke and hydrogen peroxide. This was done using a reporter plasmid. RESULTS: After 1 exposure to smoke, there was no change in biofilm formation. However, after 2 and 3 exposures, the biofilm formed had an increased mass (P < .05). With respect to oxidative stress in the form of H(2)O(2), bacterial cultures demonstrated a dose- and time-dependent induction of biofilm formation compared with control conditions. Gene expression following repetitive smoke exposure demonstrated an increase in expression of pilF, flgK, algC, and lasI genes (P < .05); a decrease in rhlA (P < .05); and no significant change in the lasB gene (P = 0.1). Gene expression following H(2)O(2) exposure demonstrated an increase in pilF (P < .05), whereas the other genes failed to demonstrate a statistical change. CONCLUSIONS: Repetitive tobacco smoke exposure leads to molecular changes in biofilm-related genes, and exposure to oxidative stress in the form of H(2)O(2) induces biofilm growth in PAO1. This could represent adaptative changes due to oxidative stress or chemically mediated through any of the several chemicals encountered in tobacco smoke and may explain increased biofilm formation in microbes isolated from smokers.

RESUMO

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) infection has been described in multiple areas of the head and neck. Recently, otolaryngologists have recognized MRSA infection in the glottis. We describe 2 cases of MRSA laryngitis with divergent clinical presentations: acute airway obstruction and recalcitrant hoarseness. METHODS: Report of 2 cases and review of the literature. RESULTS: In the first case, a 44-year-old woman presented with near aphonia despite maximal medical therapy. Examination showed diffuse erythema and edema of the endolarynx with yellowish plaques lining the glottis and supraglottis. Complete resolution was achieved with long-term trimethoprim-sulfamethoxazole. In the second case, a 54-year-old woman presented with recent-onset hoarseness with rapid progression to respiratory distress and biphasic stridor. Endoscopy revealed exuberant granulation tissue in the glottis with a narrowed airway. Treatment required prolonged courses of antibiotics and steroids. Diagnosis in both cases was confirmed with biopsies taken during direct laryngoscopy. CONCLUSIONS: MRSA treatment is a growing part of otolaryngologic practice and should be included in the differential diagnosis of hoarseness and stridor.

RESUMO

In recent years, there has been a better understanding of the aging process. In addition to changes occurring in the skin envelope, significant changes occur in the subcutaneous fat and craniofacial skeleton. This has led to a paradigm shift in the therapeutic approach to facial rejuvenation. Along with soft tissue repositioning, volumizing the aging face has been found to optimize the result and achieve a more natural appearance. Early in the aging process, when there has not been a significant change to the face requiring surgical intervention, fillers alone can provide minimally invasive facial rejuvenation through volumizing. Multiple injectable soft tissue fillers and biostimulators are currently available to provide facial volume such as hyaluronic acid, calcium hydroxylapatite, poly-L-lactic acid, polymethyl methacrylate, and silicone. A discussion of the morphological changes seen in the aging face, the properties of these products, and key technical concepts will be highlighted to permit optimum results when performing facial volumizing of the upper, middle, and lower thirds of the face. These fillers can act as a dress rehearsal for these patients considering structural fat grafting.

RESUMO

OBJECTIVE: (1) To develop a method for quantification of osteotome sharpness in a rhinoplasty model, using artificial bone; (2) to demonstrate changes in osteotome sharpness over multiple uses; and (3) to compare osteotomes from different manufacturers in terms of sharpness and cost. STUDY DESIGN: Prospective surgical model. SETTING: Academic hospital and engineering research facility. METHODS: Osteotomes were used to make 4-cm cuts through 4-mm wedges of artificial bone. Sharpness was assessed at baseline and following 1, 4, 7, and 10 uses by measuring the load required to cut a #2 Prolene suture. Changes in sharpness from baseline were measured over time, and comparison of manufacturers was performed using analysis of variance (ANOVA). Cost per use was computed for each osteotome. RESULTS: Five osteotomes were tested (Biomet, Black & Black, Miltex, NexEdge, Storz). At baseline, the Storz osteotome was sharpest (1.74 lb, P < .001), followed by Miltex and Biomet (2.50 lb, 2.68 lb) and NexEdge and Black & Black (3.48 lb, 3.40 lb). All osteotomes except NexEdge (P = .098) demonstrated significant decreases in sharpness over time (P = .02 to P < .001), although relative changes and absolute sharpness varied greatly. ANOVA demonstrated Storz to be significantly sharper at all time points (P < .001). Storz and Miltex were superior in cost-per-use analysis. CONCLUSION: Sharp osteotomes are important in cosmetic and functional rhinoplasty. Instruments may appear the same but can be quite dissimilar in efficacy and cost. Indeed, relative efficacy has not been previously tested. Quantitative analysis performance and cost-effectiveness analyses are reported here and can assist the surgeon in selection and maintenance of instruments.

RESUMO

Management of the crooked nose and valve obstruction is a challenge for even the most experienced rhinoplasty surgeon. Optimal treatment to restore a functional airway and improve cosmesis requires addressing the nasal valves. Several different techniques are available to guide the rhinoplasty surgeon to achieve the best outcome.

RESUMO

OBJECTIVE: To assess the relative sharpness of osteotomes after multiple uses, routine maintenance, and sharpening. METHODS: This prospective clinical study and mechanical model quantified the relative sharpness of identical osteotomes at baseline; after 3, 6, and 9 uses; and after sharpening techniques compared with osteotomes from hospital central supply. The Instron universal tester developed a force-displacement curve as the osteotome blade cut a standardized suture. Force required to cut the suture is inversely proportional to osteotome sharpness. RESULTS: For osteotomes 1, 2, and 3, dullness occurred after 9 uses (4.836 lb; P < .001), 6 uses (4.431 lb; P < .005), and 3 uses (4.093 lb; P < .02), respectively. Osteotome 1 was professionally sharpened after 9 uses and retested (3.156 lb); results were similar to those for an osteotome used 6 times (3.160 lb). Additional sharpening showed significantly poorer performance (7.737 lb; P < .001 at baseline and after 9 uses). Osteotome 3 was hand sharpened after 6 uses and retested (7.750 lb; baseline P < .001). Two osteotomes from central supply required almost twice the cutting force relative to the senior author's osteotomes. CONCLUSIONS: Although osteotome performance decreased significantly over time, professional sharpening only achieved results similar to an osteotome used 3 to 6 times. Further resharpening seems detrimental to performance. Surgeons may want to consider osteotomes disposable instruments.

RESUMO

OBJECTIVE: To quantitatively evaluate a dual-modality treatment that combines autologous structural fat grafting and carbon dioxide (CO(2)) laser resurfacing for perioral and lower face rejuvenation. METHOD: Retrospective review of patients undergoing rejuvenation by a single surgeon between 2005 and 2009. A blinded expert rated photographs on three scales, each with a range of 1 (no abnormality) to 5 (severe abnormality): (i) perioral fine rhytids; (ii) deep folds; and (iii) pigmentary or cutaneous abnormalities. Within-subject comparisons were generated. Results were correlated with skin type (Fitzpatrick) and baseline photodamage (Glogau). A test for effect of adjunctive procedures was performed. RESULTS: Seventeen patients were included (all female, mean age 61 years). Significant postoperative improvement was noted for perioral fine rhytids (3.1 to 1.7, p < 0.0001); deep folds (3.4 to 2.0, p < 0.00001); and pigmentation (2.5 to 1.9, p = 0.02). Fitzpatrick skin type was inversely correlated with improvement in pigmentation scores (r = -0.78), while the Glogau score correlated with improvement of fine rhytids (r = 0.76). No significant effect of adjunctive procedures was found. No complications occurred, though fat grafts resorbed in one patient. CONCLUSIONS: Concurrent structural fat grafting and CO(2) resurfacing result in quantifiable improvement of perioral and lower face aesthetics in relation to baseline characteristics and independent of adjunctive surgical procedures.

RESUMO

Nasal reconstruction provides a challenging task for any facial plastic surgeon. In performing reconstructive surgery on the nose, one must balance both the functional aspects of the nasal airway with the aesthetic responsibilities of being the central fixture of the face. Before performing surgery, the surgeon must grasp the importance of the anatomic nasal relationships and subunits, the physiology of the skin, the flaps or grafts used to reconstruct these areas, and the basic steps in wound healing. Accurate preoperative planning and analysis of the nasal defect are also vital to producing both an aesthetic and functional nose.

RESUMO

Microvascular reconstruction of nasal defects is a complex procedure and must consider 3 nasal components: skin, osteocartilaginous framework, and intranasal lining. These layers can be reconstructed with various flaps and grafts. The commonly used flaps are the first dorsal metacarpal flap, dorsalis pedis flap, auricular helical rim flap, and radial forearm and prelaminated flaps. These flaps can be composed of skin and cartilage or skin and bone. The decision is based on the patient's needs taking into consideration the extent of the defect and presence or absence of nasal septum and columella.

RESUMO

Over the last two decades, enormous effort has been focused on developing virus-based gene delivery vectors to target the respiratory airway epithelium as a potential treatment for cystic fibrosis (CF) lung disease. However, amongst other problems, the efficiency of gene delivery to the differentiated airway epithelial cells of the lung has been too low for clinical benefit. Although not a target for CF therapy, the nasal epithelium exhibits cellular morphology and composition similar to that of the lower airways, thus representing an accessible and relevant tissue target for evaluating novel and improved gene delivery vectors. We previously reported that replication-competent human parainfluenza virus (PIV)-based vectors efficiently deliver the cystic fibrosis transmembrane conductance regulator gene to sufficient numbers of cultured CF airway epithelial cells to completely correct the bioelectric function of CF cells to normal levels, resulting in restoration of mucus transport. Here, using an in vitro model of rhesus airway epithelium, we demonstrate that PIV mediates efficient gene transfer in rhesus epithelium as in the human counterpart. Naive rhesus macaques were inoculated intranasally with a PIV vector expressing rhesus macaque α-fetoprotein (rhAFP), and expression was monitored longitudinally. rhAFP was detected in nasal lavage fluid and in serum samples, indicating that PIV-mediated gene transfer was effective and that rhAFP was secreted into both mucosal and serosal compartments. Although expression was transient, lasting up to 10 days, it paralleled virus replication, suggesting that as PIV was cleared, rhAFP expression was lost. No adverse reactions or signs of discomfort were noted, and only mild, transient elevations of a small number of inflammatory cytokines were measured at the peak of virus replication. In summary, rhAFP proved suitable for monitoring in vivo gene delivery over time, and PIV vectors appear to be promising airway-specific gene transfer vehicles that warrant further development.

RESUMO

Due to the proximity of the lacrimal duct and sac to the uncinate process, occult injury to the lacrimal drainage system is common during uncinectomy and maxillary antrostomy. Fortunately, these injuries do not often progress to develop clinical symptoms as most either heal on their own, or drain into the middle meatus. In the event that injury to the lacrimal drainage system does become clinical evident, symptoms will present within the first two weeks following surgery. These symptoms may resolve over the ensuing weeks as the intranasal inflammation resolves. In cases of persistent epiphora, determination of the level of obstruction is critical for proper intervention. This can be achieved with several office-based studies as well as radiographic studies. If the obstruction is in the lacrimal duct, dacryocystorhinostomy is a highly successful surgical procedure. However, complications do occur with inadvertent violation of the orbit and cranial vault the subject of substantial publications while lacrimal duct injury (LDI) following FESS has been relatively neglected.

RESUMO

Sinonasal polyps affect a small but significant percentage of patients with chronic sinusitis. Treatments vary and range from oral and topical medical treatments to surgical removal. Corticosteroids typically have been regarded as the gold standard medical treatment for sinonasal polyps. Delivery of steroids is traditionally via oral or topical means. Over the years, otolaryngologists have also found that intrapolyp injection of corticosteroids is an effective means to treat some patients with sinonasal polyps. This article reviews the prevalence, pathophysiology, and medical treatment options for sinonasal polyps. Focused attention is paid to treatment with steroid injections, including a review of its associated risks and benefits.

RESUMO

Chronic rhinosinusitis is a common disease resulting from inflammation of the sinonasal mucosa. It has long been recognized that patients with chronic rhinosinusitis have impaired capacity to clear sinonasal secretions. However, the cause of this pathologic process is not well understood. In this article the components of mucociliary clearance, including cilia, mucus production, and cilia beat frequency, are reviewed and alterations of the system discussed regarding contribution to the disease process.
