ABSTRACT

BACKGROUND: The presence of a vascular, blue linear discoloration on the nasal root of infants and young children is a frequent incidental feature, rarely reported in the medical literature. It is related to the trajectory of the transverse nasal root vein (TNRV). OBJECTIVE: To study the frequency and clinical characteristics of the vascular discoloration of the nasal root in children. METHODS: A prospective study was performed to address the presence or absence of vascular discoloration of the nasal root in all children under 6 years of age attending a pediatric dermatology clinic from November 2022 to November 2023. Data on age and skin phototype (Fitzpatrick classification I-VI) were also collected. RESULTS: Of 701 patients examined, 345 (49.2%) presented with a vascular discoloration of the nasal root. This was present in 97 of 193 (50.3%), 127 of 261 (48.7%), and 121 of 247 (49.0%) patients for the age groups 0-1, 1-3, and 3-6 years, respectively. The presence of vascular discoloration of the nasal root was more frequent in patients with lighter Fitzpatrick skin phototypes: 49 of 69 (71.0%) phototype II, 157 of 290 (54.1%) phototype III, and 137 of 337 (40.7%) phototype IV. CONCLUSIONS: A vascular discoloration of the nasal root is a frequent skin feature in infants and children, persisting at least until the age of 6. It does not constitute any medical problem aside from cosmetic concern and parents can be reassured of its benign nature. We propose the medical term "prominent TNRV" to describe this condition.

ABSTRACT

For small defects of the anterior nasal ala, a V-Y pedicle advancement flap within the subunit is a useful repair option. Here we propose a modification of this technique, utilising careful dissection to identify inferior perforators of the superior alar artery. Basing this flap on a visualised vascular pedicle aims to prevent common complications of internal mucosal buckling and free margin notching, by allowing more extensive dissection without compromising the vascularity of the flap.

ABSTRACT

ABSTRACT: Composite full-thickness nasal defects that include adjacent facial units still remain a challenge for reconstructive surgeons. The commonly used auricular free flap (AFF) might not be sufficient for full coverage of a defect, and radial forearm free flap (RFFF) lacks the rigid component for nasal framework. Therefore, the authors present a chimeric flap combined of both AFF and RFFF for the reconstruction of extended nasal defects. Auricular free flap enables the restoration of the exact contour of nose, and it preserves similar texture and color of the skin. Moreover, its harvesting results in minimal deformity of donor site. Radial forearm free flap gives the possibility of covering extensive defects of the facial units thanks to its elasticity and long vascular pedicle. The combination of both flaps seems to be an optimal solution for the reconstruction of extended nasal defects, giving satisfactory aesthetic results. Also, it might not require any further corrections, remaining a one-stage procedure.

ABSTRACT

The facial artery is the main artery supplying blood to the face and is known to have facial branches of the inferior labial, superior labial, lateral nasal and angular arteries. These known major branches of facial artery run medially, however, there are sometimes branches of the facial artery heading laterally. The purpose of the present study was to investigate the lateral branches of the facial artery in face. We dissected facial branches of the facial artery in 74 cadaveric hemifaces. We investigated the presence of the lateral branches of the facial artery. Following parameters were investigated: lateral branch presence, the location of its origin, and the lateral branch diameter. Among the lateral branches, we evaluated the prevalence and diameter of the premasseteric branch. Lateral branches were observed in 48 of the 74 hemifaces (64.9%). The total number was 81 in the 48 hemifaces. The most common origin was between the inferior border of the mandible and inferior labial artery origin (42 of 81, 51.9%). The mean diameter of all lateral branches of the facial artery was 0.7 mm. Among the lateral branches, the premasseteric branches were present in 38 of 74 specimen (51.4%) and the mean diameter was 0.8 mm. The lateral branches of the facial artery may be registered in Terminologia Anatomica based on their prevalence. Accurate knowledge of the anatomy of the lateral branches of the facial artery is helpful for clinicians to avoid complications during facial procedures or maxillofacial surgeries.

ABSTRACT

In nasal reconstruction, it is necessary to replace all anatomic layers in order to reinstate correct aesthetics. The most apt donor site to use in order to cover the nose has been recognized as forehead skin. Traditionally 2 phases are required to reconstruct the forehead flap; however, an intermediate third phase was described by Millard which is between transfer of the flap and division of the pedicle. These methods will be compared in this study with regard to both complication rates and aesthetic results in high vascular risk patients.46 patients were enrolled in the study, all of whom were undergoing either total or subtotal nasal reconstruction from January 2001 to March 2018. The 2-step technique (2S Group) was performed on 30 patients and the 3-step technique (3S Group) was performed on 16. Evaluation questionnaires were completed by patients and a plastic surgeon who was extraneous to the study to evaluate aesthetic satisfaction. Complications other than flap necrosis such as infection, wound dehiscence and hematoma were recorded. VAS and Likert mean values, used to evaluate aesthetic satisfaction, were examined with a Student t test and were discovered to be relevant. Complication rates studied with Fisher exact test showed no statistically significant difference between the 2 groups. The 3-phase method for nose reconstruction using a forehead flap represents a better functional and aesthetic option for patients at high vascular risk.

ABSTRACT

PURPOSE: The aims of this study were to measure the incidence and severity of nasal septum injury in premature infants receiving continuous positive airway pressure (CPAP) via a noninvasive thin-walled cannula, and to evaluate the effect of a polyvinyl chloride foam barrier dressing in reducing these injuries. DESIGN: Retrospective chart review, comparison cohort study. SUBJECTS AND SETTING: The sample comprised 235 neonates with a gestational age of 28 weeks or younger. Their mean gestational age was 26 weeks (range 22-28 weeks) and mean birth weight was 840 g (range 430-1320 g). The study setting was a level 4, regional neonatal intensive care unit housed in a 200-bed freestanding children's hospital located in the Northeastern United States. METHODS: Data were collected during 3 periods. During all 3 data collection periods, we used a soft, thin-walled nasal cannula, with a relatively short, binasal prong interphase and small diameter tubing connected to a ventilator circuit capable of transmitting positive airway pressure in neonates. During data collection periods 1 and 3, we used a polyvinyl foam barrier dressing as a preventive intervention against nasal skin damage; specifically, we placed a precut barrier on the prongs to protect the nasal skin. One side of the barrier foam has an adhesive surface, which was placed against the prongs. Study period 2 differed; during this period neonates were treated with the nasal cannula without the foam barrier based on manufacturer experience suggesting the foam barrier is not needed for prevention of skin damage. Pressure injuries (PIs) that occurred during each study period were staged according to National Pressure Ulcer Advisory Panel definitions. RESULTS: Eighty neonates were evaluated during study period 1 (thin-walled nasal cannula plus foam barrier). We evaluated 27 neonates during period 2 (thin-walled nasal cannula and no foam barrier) and 128 were evaluated during study period 3 (thin-walled nasal cannula plus foam barrier). Six neonates (7%) developed PIs during period 1, and 2 (1.5%) developed during study period 3. All were stage 1 and 2 PIs, no full-thickness injuries, also referred to as columella necrosis developed during use of the thin-walled nasal cannula in combination with the foam barrier dressings. In contrast, 13 PIs (48%) of neonates managed during data collection period 2 (thin-walled nasal cannula with no foam barrier) developed PI, and 40% experienced stage 3 PI or columella necrosis. This difference reflects a 6-fold increase in nasal injury occurred when nasal continuous positive airway pressure (NCPAP) was administered without use of the protective barrier dressing. CONCLUSION: We found clinically relevant difference in the occurrences of nasal PI in neonates managed with NCPAP; occurrences of stage 3 PI were 6-fold higher when a thin-walled cannula was used without a protective foam barrier dressing.

ABSTRACT

STUDY OBJECTIVE: The primary objective of this study is to compare the effectiveness of 3 treatment protocols to stop anterior epistaxis: classic compression, nasal packing, and local application of tranexamic acid. It also aims to determine the frequency of rebleeding after each of these protocols. METHODS: This single-center, prospective, randomized controlled study was conducted with patients who had spontaneous anterior epistaxis. The study compared the effect of 3 treatment options, tranexamic acid with compression but without nasal packing, nasal packing (Merocel), and simple nasal external compression, on the primary outcome of stopping anterior epistaxis bleeding within 15 minutes. RESULTS: Among the 135 patients enrolled, the median age was 60 years (interquartile range 25% to 75%: 48 to 72 years) and 70 patients (51.9%) were women. The success rate in the compression with tranexamic acid group was 91.1% (41 of 45 patients); in the nasal packing group, 93.3% (42 of 45 patients); and in the compression with saline solution group, 71.1% (32 of 45 patients). There was an overall statistically significant difference among the 3 treatment groups but no significant difference in pairwise comparison between the compression with tranexamic acid and nasal packing groups. In regard to no rebleeding within 24 hours, the study found rates of 86.7% in the tranexamic acid group, 74% in the nasal packing group, and 60% in the compression with saline solution group. CONCLUSION: Applying external compression after administering tranexamic acid through the nostrils by atomizer stops bleeding as effectively as anterior nasal packing using Merocel. In addition, the tranexamic acid approach is superior to Merocel in terms of decreasing rebleeding rates.

ABSTRACT

OBJECTIVE: Dermal fillers are an important tool in the field of aesthetic dermatology. Fillers are relatively noninvasive and easy to use but are not free of secondary complications. The main complications are vascular and are due to either the compression of an artery or the direct introduction of the product into the arterial lumen. The aim of this study is to provide an overview of the vascular territories of the face to avoid many possible complications when using facial fillings. Anatomical localization of the main arterial supply to the face has been described to assess the risk of vascular injury. METHODS: The authors dissected 17 hemifaces of embalmed adult cadavers that had previously been injected, through the common carotid artery, with latex containing a red dye. RESULTS: A topographic distribution was generated by facial regions following a clinical approach from where the facial fillings were placed and related to the pathways of the arteries. Following these criteria, we established 8 topographic regions (I-VIII) that indicate the main vascular problems of each of these regions. Detailed anatomical localizations of the main arteries in these topographic regions of the face and their relationships are described. CONCLUSIONS: The highest index of vascular lesions and especially visual alterations occurred for fillings of the upper third of the face. To prevent and avoid this type of lesion, it is advisable to avoid, as much as possible, treatments with filling materials in the upper third of the face, mainly including the glabellar and nasal region (III) and supraorbital region (VIII).

ABSTRACT

PURPOSE: The facial skin blood flow (SkBF) shows regional differences in the responses to a given stimulation. The facial SkBFs, especially in the eyelid and nose exhibit unique response to physiological and psychological stimuli, but the mechanisms inducing those regional differences remain unclear. To investigate whether the regional differences in the local control of vasomotion in facial vessels correspond to the regional differences in facial SkBF response, we monitored the relative change of facial SkBF to regional thermal stimulation. We hypothesized that heat stimulation dilates the cutaneous vessels in the eyelid, while cold stimulation constricts those in the nose, which was based on previous findings METHODS: A thermal stimulator was used to apply temperature increase (from 20 to 40 °C at 2 °C/min) and decrease (from 40 to 20 °C at 2°C/min) in a randomized order to the right eyelid, nose, right cheek, and forehead of 14 healthy young males. The facial SkBF was measured for 10 s using laser-speckle flowgraphy when temperatures of 20 °C, 30 °C, and 40 °C had been applied for 30 s in both trials. RESULTS: The SkBF in the eyelid did not change significantly during any thermal stimulation, and the nasal SkBF did not decrease significantly during cold stimulation. The SkBFs in the cheek and forehead increased significantly with the applied temperature. CONCLUSIONS: These findings indicate that a large regional variation exists in facial skin blood flow response to local heating or cooling and that the regional variation did not correspond to the unique SkBF responses in the previous studies.

ABSTRACT

PURPOSE: To investigate the clinical profile and outcomes of different treatment strategies in patients hospitalized for spontaneous severe epistaxis. METHODS: This is a retrospective descriptive study of a case series of patients hospitalized for epistaxis in the University Hospital of Ghent between 2005 and 2012. RESULTS: 124 patients with, respectively, 132 episodes were included. 64% were male. The mean age was 65 years. 73% had comorbidities of which arterial hypertension was the most common. 61% were taking one or more antithrombotics and in 25.7% a recent change in the medication schedule took place. 47% of the episodes necessitated a vascular intervention. The most performed surgery was endoscopic sphenopalatine artery ligation. The 1-year success rate of conservative treatment was 47% and of vascular intervention 81%. No significant difference between the recurrence rates and need for vascular intervention of the different comorbidities and medications was detected using Pearson chi-squared and Fisher's exact testing. The overall 5-year survival rate was 83.6%. CONCLUSIONS: The typical pattern of a patient presenting with severe epistaxis was a patient in the sixth decade, male, suffering from comorbidities and taking one or more antithrombotic agents. Based on the above-mentioned success rates of the different treatment options, we think all centres treating epistaxis should apply a well-defined protocol to guide the decision when to proceed with surgery. Furthermore, prospective research needs to precisely investigate the role played by comorbidities and their treatment in the occurrence of epistaxis and to test the effectiveness of proposed algorithms.

ABSTRACT

Various local flaps have been defined for small skin defects of the nose. However, the repair of large nasal defects is only possible with flaps allowing a large tissue transfer, such as a free flap, forehead flap, and nasolabial flap. In this study, large nasal defects were reconstructed with extended central artery perforator propeller (CAPP) flaps in an attempt to describe a single-stage procedure as an alternative technique to the median forehead flap. Thirteen large nasal skin defects, including dorsum and nasal sidewall and/or dome, were repaired with a CAPP flap between January 2015 and March 2018. A total of 13 patients aged 19 to 92 years were included. The mean follow-up period was 14.9 months. Pathological diagnoses were basal cell carcinoma in 5 patients, squamous cell carcinoma in 6 patients, and trauma in 2 patients. Defect size ranged between 3 × 3 and 4 × 5 cm. Flap size ranged between 3 × 7 and 5 × 10 cm. No major complications including total flap failure, hematoma, or infection were observed. However, a partial flap necrosis occurred in 1 patient. In 3 patients, scar revision surgery was performed at the postoperative period. In conclusion, CAPP flap use is a safe and reliable option to repair large nasal defects. This flap is able to cover large nasal defects including dorsal, dome, and nasal sidewall defects in a single-stage procedure. Requiring no pedicle separation, this flap is an alternative option to the conventional median forehead flap.

ABSTRACT

Epistaxis is a common emergency encountered by primary care physicians. Up to 60% of the general population experience epistaxis, and 6% seek medical attention for it. More than 90% of cases arise from the anterior nasal circulation, and most treatments can be easily performed in the outpatient setting. Evaluation of a patient presenting with epistaxis should begin with assessment of vital signs, mental status, and airway patency. When examining the nose, a nasal speculum and a good light source, such as a headlamp, can be useful. Compressive therapy is the first step to controlling anterior epistaxis. Oxymetazoline nasal spray or application of cotton soaked in oxymetazoline or epinephrine 1: 1,000 may be useful adjuncts to compressive therapy. Directive nasal cautery, most commonly using silver nitrate, can be used to control localized continued bleeding or prominent vessels that are the suspected bleeding source. Finally, topical therapy and nasal packing can be used if other methods are unsuccessful. Compared with anterior epistaxis, posterior epistaxis is more likely to require hospitalization and twice as likely to need nasal packing. Posterior nasal packing is often associated with pain and a risk of aspiration if it is dislodged. After stabilization, patients with posterior packing often require referral to otolaryngology or the emergency department for definitive treatments.

ABSTRACT

OBJECTIVE: To define anatomical variations associated with arterial blood supply of the nose which has clinical implications on the management of different disorders, especially intractable posterior epistaxis. STUDY DESIGN: Case series. METHODS: Selective angiography of external and internal carotid arteries of 100 patients scheduled for routine angiography was done. RESULTS: Different anatomical variations were documented. The ophthalmic artery can arise from the middle meningeal artery in 1% while ethmoidal arteries can be absent in 5%. The maxillary artery courses as 2 loops in the pterygopalatine fossa in 64% of cases where the descending palatine artery originates before the first loop or on its top so that caution is needed in controlling epistaxis. The sphenopalatine artery has different patterns of branching and may have more than 2 branches in 18% of cases. In 19% of cases, there is cross-circulation between both sides through the nasal blood supply. CONCLUSION: Angiographic study of the nose is a very helpful tool for accurate knowledge of anatomical variations of the arteries with a tremendous effect on our surgical approaches and techniques for the management of different diseases in the nasal region, especially intractable posterior epistaxis.

ABSTRACT

Nasal columellar is a complex area to reconstruct due to its unique esthetic and functional characteristics. Malignancy, trauma, infection, and esthetic surgery complications can cause columellar defect. Among many surgical plans, nasolabial island flap is most commonly used. However, flap congestions occasionally occur which inevitably lead to leech therapy. The authors introduce reverse lateral nasal artery pedicled nasolabial island flap, which has lower risk of postoperative complications.

ABSTRACT

The facial artery is the major vessel supplying blood to the face so its location and course are very important for the safe manipulation of both surgical and non-surgical interventions. This study documents current anatomical information about the facial artery and its tributaries. The terminology of the facial artery tributaries was revisited with reference to the Terminologica Anatomica and novel nomenclature was suggested with anatomical features. The tributaries to the lower lip (inferior labial artery), labiomental region (horizontal and vertical labiomental artery), upper lip (superior labial artery), nose (inferior and lateral alar artery and nasal septal artery), angular and ocular region (angular artery and detoured branch) and the course, layers and location of the facial artery main trunk were revisited with contemporary anatomical studies. The facial artery and its tributaries have close topographical connections to the facial expression muscles, nasolabial groove, and vermilion border, and these also distinguish facial landmarks comprising the cheilion, stomion, and gonion. Interestingly, in contrast to previous descriptions, some terminal branches did not take a straight course but a detoured course. The angular artery was connected to the ophthalmic artery branches and in some cases did not originate from the facial artery. Vascular complications of the facial artery tributaries are frequently seen in the angular, dorsum of the nose, tip of the nose, and glabellar region. This detailed review focusing on facial arterial topography in the various areas of the face would help to enhance quality of treatment. Clin. Anat. 31:99-108, 2018. © 2017 Wiley Periodicals, Inc.

ABSTRACT

The nose is a complex structure important in facial aesthetics and in respiratory physiology. Nasal defects can pose a challenge to reconstructive surgeons who must re-create nasal symmetry while maintaining nasal function. A basic understanding of the underlying nasal anatomy is thus necessary for successful nasal reconstruction.

ABSTRACT

Background The science and technical acumen in the field of vascularized composite allotransplantation has progressed rapidly over the past 15 years, and transplantation of specialized units of the face, such as the nose, appears possible. No study to date has evaluated the technical feasibility of isolated nasal unit transplantation (NUT). In this study, we explore the anatomy and technical specifics of NUT. Methods In this study, four fresh cadaver heads were studied. Bilateral vascular pedicle dissections were performed in each cadaver. The facial artery was cannulated and injected with food dye under physiologic pressure in two cadavers, and with lead oxide mixture in two cadavers to evaluate perfusion territories supplied by each vascular pedicle. Results The facial artery and vein were found to be adequate pedicles for NUT. Divergent courses of the vein and artery were consistently identified, which made for a bulky pedicle with necessary inclusion of large amounts of subcutaneous tissue. In all cases, the artery remained superficial, while the vein coursed in a deeper plane, and demonstrated consistent anastomoses with the superior transverse orbital arcade. While zinc oxide injection of the facial artery demonstrated filling of the nasal vasculature across the midline, dye perfusion studies suggested that unilateral arterial inflow may be insufficient to perfuse contralateral NUT components. Discrepancies in these two studies underscore the limitations of nondynamic assessment of nutritive perfusion. Conclusion NUT based on the facial artery and facial vein is technically feasible. Angiosome evaluation suggests that bilateral pedicle anastomoses may be required to ensure optimal perfusion.

ABSTRACT

PURPOSE: Epistaxis constitutes a significant proportion of the Otolaryngologist's emergency workload. Optimal management differs in relation to the anatomic origin of the bleeding. The outcome of our study was to determine which artery(ies) could be considered as the cause of severe bleeding in the context of severe epistaxis. METHODS: Fifty-five procedures of embolization preceded by angiography were reviewed. Medical records of interventionally treated patients were analysed for demographics, medical history, risk factors and clinical data. Angiographic findings were also assessed for active contrast extravasation (blush), vascular abnormality and embolised artery. RESULTS: Previous angiography showed an active contrast extravasation in only 20 procedures. The most common bleeding source was the sphenopalatine artery (SPA) followed by anterior ethmoïdal artery (AEA) and facial artery. Majority of multiple or bilateral extravasations occured in patients with systemic factors. CONCLUSIONS: A better understanding of the potential bleeding source might help and limit the risk of treatment failures. Our study confirms that the SPA is the most common cause of severe bleeding. We also emphasise the role of the AEA not only in traumatic context. Others arteries are rarely involved except in patients with comorbidities or frequent recurrences.

ABSTRACT

PURPOSE: To study angular and temporal vein engorgement following periorbital hyaluronic acid gel (HAG) injection. METHODS: In this retrospective study, the authors reviewed the photographs of 805 patients who had periorbital HAG injection at Jules Stein Eye Institute Oculoplastic Clinic between January 2004 and January 2014. HAG injections were used to fill the orbital hollow, zygomatic hollow, septal confluence hollow, and cheek. The inclusion criteria were patients who had at least 1 pre-, immediate post-, and late postinjection photographs. Immediate postinjection photographs were taken right after HAG injection, and late postinjection photographs were taken at the following visit before any injection. The exclusion criteria were patients with any previous ocular surgery 6 months before filler injection, patients with orbital diseases, and patients who had HAG injections for functional purposes. The photographs were evaluated for the presence of angular and temporal vein engorgement at any of the injections during the follow-up visits. The photographs of eyes with vein engorgement were graded on a scale of 0 (no engorgement), 1 (mild engorgement), 2 (moderate engorgement), and 3 (severe engorgement). RESULTS: There were 78 eligible patients (156 orbits; 68 females and 10 males) with average age of 59.4 ± 13.4 years. The authors found 18 orbits of 12 patients (15.4%; 6 unilateral and 6 bilateral) with angular vein engorgement at least 1 time after HAG injection during the follow-up visits. The frequency of temporal vein engorgement was 9.1%. The mean ± SD of angular vein grading for engorgement increased from 0.72 ± 0.51 on preinjection photographs to 1.45 ± 0.88 on immediate postinjection photographs (p = 0.0001) and 0.89 ± 0.50 on late postinjection photographs (p = 0.04). The mean ± SD of angular vein grading for engorgement was 0.67 ± 0.55 on the first preinjection photographs, which increased to 1.10 ± 0.50 on the last late postinjection photographs. The difference was statistically significant (p = 0.001). CONCLUSIONS: Angular and temporal vein engorgement occurred following HAG injection in the periorbital region. The engorgement occurred immediately after injections and decreased considerably but not completely in the following visit.
