RESUMO

OBJECTIVE: To compare the accuracy of three diagnostic tests in predicting difficult laryngoscopy using Cormack and Lehane grade as the gold standard. METHODS: The cross-sectional study was conducted at the Aga Khan University Hospital, Karachi, from August 2014 to August 2015, and comprised patients who required endotracheal intubation for elective surgical procedures. The primary investigator used ratio of height to thyromental distance, upper lip bite test and the modified Mallampati test for assessing the airway correlated with laryngoscopic view based on Cormack and Lehane grading. Data was analysed using SPSS 19. RESULTS: Of the 383 patients, 59(15.4%) were classified as difficult cases of laryngoscopy. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ratio of height to thyromental distance were 84.7%, 90.1%, 60.9%, 97%, 89.3%; and those the corresponding values for the upper lip bite test were 83.1%, 89.2%, 58.3%, 96.7% and 88.3%. The values for the modified Mallampati test were 30.5%, 84.3%, 26.1%, 86.9% and 79.9% respectively. The area under receiver-operating characteristic curve for the first two tests was significantly more than for the modified Mallampati test (p<0.01). CONCLUSIONS: RHTMD and ULBT both are acceptable alternatives for prediction of difficult laryngoscopy as a simple, single bed-side test.

RESUMO

Melkersson-Rosenthal syndrome (MRS) is a rare neuro-muco-cutaneous syndrome, which is characterized by recurrent orofacial swelling, recurrent facial paralysis and fissured tongue. It has a high prevalence in young adults. Up to now, the etiology of MRS is still not clear, it may related to infection, immune deficiency and hereditary factors. The pharmacological therapy and surgery are the main treatment. Corticosteroids seems to be the drug of choice for MRS patient, but the specific dosage and therapeutic effect have not yet been determined. Surgeries of lips provide excellent results in persistentlip edema MRS cases. This article reviews the research progress on MRS, focusing on its epidemiology, etiology, histopathological characteristics, clinical manifestations, classification, diagnostic criteria, differential diagnosis and treatment, to provide information for its early diagnosis and appropriate treatment.

RESUMO

Lip repositioning surgery is a predictable surgical technique that provides a solution for patients with excessive gingival smile. This case series presents four patients with 6 to 8 mm of excessive gingival display who received a modified surgical technique using internal horizontal mattress sutures to immobilize the labial superior elevator muscle. None of the patients exhibited complications, and their healing was uneventful. All patients demonstrated predictable results and presented with stability over an average of 3.5 years of follow-up. The modified lip repositioning surgery with internal horizontal mattress sutures seems to provide reliable long-term results in patients with an excessive gingival display.

RESUMO

Acinar cell carcinoma is a tumor characterized by the proliferation of cells that resemble serous acinar cells. It accounts for 1% of all salivary gland tumors, with 90% or more of these tumors frequently occurring in the parotid gland and rarely occurring in the small salivary glands. This time, we experienced a patient suffering from synchronous double cancer, found during a full body examination and triggered by acinar cell carcinoma of the upper lip. The case involved a 76-year-old woman, with a chief complaint of swelling of her right upper lip. She became aware of the swelling of her right upper lip in May 2017, and due to a gradual increase in the size thereof, she visited our department in December. Eight days after her initial consultation, a total biopsy was performed under local anesthesia, upon which the patient was diagnosed with acinar cell carcinoma. In January 2018, we asked our otolaryngologist to conduct a close examination of the parotid gland. Although computed tomography indicated no problems with the parotid gland, pancreatic head cancer was suspected. She visited the Department of Gastroenterology at our hospital in February and was diagnosed with pancreatic cancer (stage IVb) by an endoscopic biopsy in March. Chemotherapy was initiated the same month, but she died in January 2020.

RESUMO

AIM: The purpose of the present study was to determine opinions about beauty and attractiveness, to distinguish the rate of variables among gender and age groups, and to evaluate and determine the most attractive lip surface area (SA) and upper to lower lip ratio. MATERIAL AND METHODS: The study was performed in two phases: In phase 1, a set of 10 internet-based frontal facial images were used to generate 5 synthetic images that were distributed to participants, who were asked to choose the most and least attractive image. A total of 312 responses were received in this phase. In phase 2, the images that had been chosen in phase 1 were manipulated to reduce or augment the lip size. Five images had variable lip SA, and three had variable upper to lower lip ratio. A total of 687 responses were received in phase 2. RESULTS: The majority of respondents preferred a more natural lip SA, while in terms of upper to lower lip ratio, 1:2 was considered the most attractive ratio, and 2:1 the least attractive. CONCLUSION: The lips have a great impact on the perception of beauty. Age, gender, trends, and social media all play a role in determining what is considered to be the most attractive lip SA and upper to lower lip ratio. CLINICAL SIGNIFICANCE: The lip SA and upper to lower lip ratios determined in this study may provide guidelines for clinicians in the improvement of facial esthetics. Current trends and social media are the gold standard today regarding patient perception of beauty and esthetics.

RESUMO

Cheilitis is a general term for various types of inflammatory diseases that occur on the lips. The etiology differs and the clinical manifestations and pathological features overlap, leading to difficulties in clinical diagnosis. Reasonable classification is conducive to the diagnosis of cheilitis. However, its classification is difficult because of its cha-racteristics. At present, scholars have proposed two different classification schemes, but a unified classification standard has not yet been established. We classified cheilitis based on its etiology, clinical manifestations, pathological characteristics, and relationship with systemic and special diseases on the basis of special medical reports and by combining clinical practice experience and summarizing previous cheilitis diagnosis and treatment literature. In accordance with this classification method, we proposed suggestions for the clinical diagnosis of cheilitis to provide a reference for the clinical diagnosis and treatment of complex cheilitis.

RESUMO

BACKGROUND: Recent reports have surfaced from the United States Food and Drug Administration hearings in December 2020 regarding the COVID-19 vaccines and study participants who developed facial and/or lip swelling after receiving the newly developed drug. Despite an incidence rate of 0.02% in the vaccine arm of the Moderna mRNA-1273 trial, concerns have been expressed about the association of adverse reactions following soft tissue filler injections and the COVID-19 vaccines. The International Society for Dermatologic and Aesthetic Surgery (ISDS) understands these concerns and has designed the following study. METHODS: A global survey was designed to capture the incidence of adverse events related to: (1) previous soft tissue filler injections, (2) soft tissue filler injections during positive testing for COVID-19, and (3) soft tissue filler injections during and after receiving any of the COVID-19 vaccines globally available. RESULTS: The information of 106 survey participants from 18 different countries was analyzed. 80.2% (n=85) never experienced any adverse reaction following their soft tissue filler injection whereas 15.1% (n=16) experienced swelling and 4.7% (n=5) experienced pain that lasted longer than two days. Of those who received at least one dose of the COVID-19 vaccine (n=78), 94.9% reported not to have experienced any adverse reaction related to their previous soft tissue filler injection, whereas 5.1% (n=4) reported to have perceived pain that lasted longer than two days. CONCLUSION: The data collected does not support the concern for an increased risk of developing adverse reactions following soft tissue filler injections associated with the COVID-19 vaccines compared to that risk associated with other previously described triggers or the default risk following soft tissue filler injections.

RESUMO

Perioral region, although severely impacted by facial aging, is often overlooked in texts on facial rejuvenation. Sun exposure, bone resorption, dynamic contraction of the sphincteric and nonsphincteric oral musculature, gravitational pull, histological changes of the skin, and unhealthy habits all take their toll in this area. Fine wrinkling on the lips, deep nasolabial and mentolabial folds, elongation and flattening of the upper lip, downturned corners of the mouth, marionette lines, diminished vermillion and upper teeth show and chin irregularities are the main signs of this process, raising great concern amongst patients and making the perioral region the most demanded area for facial rejuvenation treatment. A huge armamentarium of surgical and nonsurgical techniques, with or without complex technology, are available to tailor patient's specific needs, from chemodenervation and mild chemical peels to operations designed to restore the size and shape of the lips. In this article we perform a comprehensive review of the contemporary treatment of the aging perioral area, detailing the most common techniques and their nuances.

RESUMO

Botulinum toxin is a protease used by the bacterium Clostridium botulinum that causes chemical denervation of skeletal muscles, producing a temporary weakening of muscle activity. Despite having a transitory effect, the application of botulinum toxin has been identified as an alternative for correcting an excessive gingival display (EGD). However, studies evaluating the maintenance of long-term results of botulinum toxin remain scarce. This study aimed to evaluate the effectiveness and duration of botulinum toxin type A in the treatment of anterior EGD. Botulinum toxin Type A was applied to 15 patients with EGD. The measurement was performed in triplicate, using a Castro Viejo dry point compass, between the central cervical portion of the upper lateral incisors to the lower portion of the upper lip, bilaterally. The measurements were performed before the application of the toxin and repeated on days 7, 14, 90, 120, and 180 after the procedure. The data were analyzed using repeated-measures ANOVA, followed by a Bonferroni. There was a statistically significant reduction between the measurements performed on the Baseline and seven days after the application of the botulinum toxin. After 180 days, approximately one-quarter of the patients in the sample did not presented EGD. Mild adverse effects were reported by 46.7% of the patients. The use of botulinum toxin type A was effective to treat EGD. After 180 days, it was still possible to observe a significant effect compared to the initial gingival exposure.

RESUMO

The literature offers limited and even conflicting information on the etiology of gummy smile. Therefore, this study aimed to evaluate smile line, hypermobile upper lip (HUL), altered passive eruption (APE), and short upper lip (SUL) distribution in a group of patients seeking dental treatment and examine their effects on gummy smile. A total of 501 individuals (265 men, 236 women) were included in the study. The patients were grouped by gingival display, and presence of HUL, APE, and SUL were evaluated. Multivariate Logistic Regression analyses were performed to investigate the impact of possible risk factors on gummy smile. Of the individuals, 173 (34.5%) had a low smile line, 127 (25.3%) had an average smile line, 146 (29.1%) had a high smile line, and 55 (10.9%) were gummy smile patients. Individuals with gummy smile were younger than the individuals with low smile line (P < .001). As for the possible risk factors for gummy smile, age (odds ratio [OR]: 0.936; 95% CI: 0.901 to 0.972; P = .001), HUL (OR: 18.85; 95% CI: 7.82 to 45.44; P < .001), and APE (OR: 8.819; 95% CI: 3.894 to 19.973; P < .001) were found to be significant together. Gender and SUL/upper lip length were not found to have any impact on gummy smile. HUL is the primary factor that increases the probability of having gummy smile, followed by APE as the secondary factor. It seems reasonable to focus on correction of the HUL for treatment in most gummy smile patients.

RESUMO

Objective: This study was focused on comparing and analyzing the soft tissue changes induced by Reverse Twin-Block (RTB) and Reverse Pull Face Mask (RPFM) in early and late mixed dentition Malay children having Class III malocclusion. Methods: This cross-sectional study includes a total sample of 95 Malay children of both early (8-9 years) and late (10-11 years) mixed dentition stages. The comparison was between 49 samples treated by RTB and 46 samples treated by RPFM. Both pre- and posttreatment changes were assessed with Holdaway's analysis using the CASSOS software. In each cephalogram, 71 anatomic landmarks were traced. Descriptive and multiple regression analyses were performed for statistical evaluation. Results: Statistically significant changes were noticed in soft tissue facial angle, subnasale to H-line, skeletal profile convexity, upper lip strain, H-line angle, lower lip to H-line, and inferior sulcus to H-line measurements. Gender disparity was noticed in upper lip strain. Other significant changes were influenced by the type of appliance. However, the mean differences were minute to notice clinically. Age difference did not have any effect on the treatment changes. Conclusions: RPFM revealed treatment outcome with more protruded upper lip than RTB.

RESUMO

INTRODUCTION: Drug induced oral erythema multiforme a rare clinical entity which involves only the lips and oral mucosa without skin involvement. These lesions are difficult in diagnosing with other oral ulcerative lesions with similar clinical manifestations. PATIENT CONCERNS: This article presents 2 case reports of Oral erythema multiforme in which drugs were the precipitating factor. Its etiopathogenesis, differential diagnosis and treatment modalities of the disease is discussed. DIAGNOSIS: Based on patient's complaints, drug history and clinical appearance, provisional diagnosis of drug induced erythema multiforme was considered. INTERVENTION: For case 1, patient was instructed to discontinue usage of drug and prescribed systemic steroid (Prednisolone 10 mg/d) for a week along with germicidal drugs to prevent secondary infection. Medication was tapered to 5 mg/d after first week.For case 2, patient was instructed to discontinue the drug and systemic steroid prednisolone 20 mg /d for 1 week with tapering dose of 10 mg/d for the second week was administered. OUTCOME: For case 1 and case 2 healing of the lesions were evident on third week of follow up. CONCLUSION: Medications should be taken under medical supervision. Over the counter drugs might lead to allergic reactions like drug induced oral erythema multiforme, which is a rare variant and needs to be differentiate from other oral ulcerative lesion for prompt management and follow-up.

RESUMO

As facial aging occurs, aesthetic changes of the nasal tip and the senile upper lip include tip ptosis, increase in skin length, loss of vermillion height and Cupid's bow, and vertical wrinkles.Regardless of the rejuvenation procedure, the lips are not to be considered as a single anatomical entity, instead they should be placed in a strong correlation with the nose. The aim of this study is therefore to demonstrate the effectiveness of the association of primary closed rhinoplasty together with indirect subnasal lip-lifting technique.A total of 45 patients were enrolled in this study and underwent primary closed rhinoplasty with indirect subnasal lip-lifting. The result showed an overall average nasolabial angle width reduction of 10.9% and lip length shortening of 23.5%, as assessed 1 year after the surgical procedure. When comparing before and after photographs and using the Subjective Global Aesthetic Improvement Scale (sGAIS), the overall satisfaction was rated 4.4 on 5, as "much improved."The authors show that lips should not be considered as a single anatomical entity but that they indeed must be placed in a strong correlation with the nose since a droopy nasal tip is likely to be considered unattractive and is often associated with the appearance of a long nose with covered philtrum and upper lip.Tip rotation to a normal nasolabial angle width could grant a beneficial impact on overall nose aesthetics; however, it may not fully balance the midface profile as it is the "lip position-to-incisal show" ratio that defines beauty, whereas the balance among forehead, nasal tip, upper lip, and chin is what defines the contour of harmonious profiles.This is the first patient series to show that the combination of closed rhinoplasty and indirect lip-lifting is a highly effective, safe, and reliable procedure to address profile rejuvenation.

RESUMO

INTRODUCTION: The objective of this research was to evaluate the correlation between 3-dimensional (3D) lip vermilion (LV) morphology and skeletal patterns as well as incisor measurements in young Chinese adults. METHODS: In all, 240 young adults were enrolled; these included 80 patients each with skeletal Class I, Class II, and Class III malocclusions, respectively. Each sagittal skeletal pattern included 40 male and 40 female subjects. Twenty-two 3D LV measurements were obtained from 3D facial scans. Skeletal and incisor measurements were evaluated on lateral cephalograms. Correlation and regression analysis were performed between soft and hard tissue measurements. RESULTS: Six of 22 LV measurements showed significant differences between male and female subjects. The 3D LV morphology showed significant differences with respect to different skeletal patterns and sex. Adults with skeletal Class III malocclusion tended to have thinner upper vermilion and fuller lower vermilion than subjects with skeletal Class II and III malocclusion. The mandibular plane angle negatively correlated with the upper-lower vermilion midsagittal curve length and surface area ratio in adults with skeletal Class I and II malocclusion, yet the vertical facial skeletal type showed no correlation in adults with skeletal Class III malocclusion. The vermilion angle, central bow angle, vermilion height, vermilion midsagittal curve length, vermilion height and width ratio, and vermilion surface area showed a significant correlation with incisor measurements. Regression analysis found that the ANB angle was an important factor affecting the upper and lower vermilion midsagittal curve length and surface area ratio. Further, the vermilion height and height and width ratio were closely correlated with the interincisal (U1/L1) angle, whereas the central bow angle was closely correlated with the maxillary incisor torque. CONCLUSIONS: Most LV morphology variables were correlated to skeletal patterns and incisor measurements. Skeletal Class III malocclusion showed significant differences in vermilion morphology. Both the sagittal and vertical skeletal pattern have effects on vermilion proportion. The incisor torque was closely correlated to vermilion shape and central bow angle and might influence the vermilion esthetics. However, the proportion of the upper and lower vermilion was mainly affected by the ANB angle.

RESUMO

INTRODUCTION: The purpose of this quantitative investigation was to assess the influence of lip prominence in relation to the esthetic line (E-line) on perceived attractiveness and threshold values of desire for treatment. METHODS: The lip prominence of an idealized silhouette male white profile image was altered incrementally between -16 mm to 4 mm from the E-line. The images were rated on a Likert scale by pretreatment orthognathic patients (n = 75), laypeople (n = 75), and clinicians (n = 35). RESULTS: In terms of perceived attractiveness, lips to E-line distance within the ranges of -12 mm to -16 mm and 0-4 mm in relation to the E-line was associated with a reduction in median attractiveness scores to below 4 in the patient and clinician groups of observers; for the lay group, the corresponding ranges were -14 mm to -16 mm and 2-4 mm. Relative lip prominence appears to be viewed as more attractive than lip retrusion. Clinicians were generally least likely to suggest treatment for varying levels of bilabial position. For a number of the images, there was reasonable agreement among clinicians and laypeople regarding whether treatment is required. For the clinician group, the only categories for desire for treatment were at a lip to E-line distance within the ranges of -14 mm to -16 mm and 2-4 mm. CONCLUSIONS: It is recommended that the range of normal variability of the prominence of the lips and threshold values of the desire for treatment be considered in planning.
