Facial Soft Tissue Augmentation With Bellafill: A Review of 4 Years of Clinical Experience in 212 Patients.

INTRODUCTION: Bellafill (Suneva Medical Inc) is a semipermanent injectable soft tissue filler composed of smooth and uniform polymethylmetacrylate (PMMA) microspheres suspended in a bovine collagen gel. It is a third generation PMMA filler, with more uniform shapes and sizes of the PMMA microspheres, which has been purported to decrease the incidence of granuloma formation. METHODS: We performed a retrospective review of our clinical experience from 2014 to 2017 with Bellafill as a soft tissue injectable filler in the following clinical scenarios: deep nasolabial folds, depressed facial acne scars, malar volume loss, temporal wasting, tear trough deformity, chin augmentation, angle of jaw augmentation, and lip augmentation. The primary outcome is the rate of adverse events, and the secondary outcome is subjective patient satisfaction. RESULTS: From 2014 to 2017, 842 syringes of Bellafill were administered to 212 patients, for a total of 417 procedures. Of the 417 procedures, 96 (23.0%) were for acne scars, 82 (19.7%) malar volume restorations, 65 (15.6%) nasolabial fold augmentations, 45 (10.8%) chin augmentations, 42 (10.1%) tear trough volume restorations, 28 (6.7%) temple volume restorations, 25 (6.0%) rhinoplasty touch-ups for small areas of nasal depression, 22 (5.3%) lip augmentations, and 12 (2.9%) jaw angle augmentations were performed. A range of 1 to 12 syringes were injected into each patient, over 1 to 3 sessions; 6 cases of adverse events occurred (1.4%). There were 4 cases of solitary nodules in the injection site, 1 case of lower eyelid oedema which persisted for 3 months and 1 case of lower lip oedema which resolved within hours. Patient satisfaction rates ranged from 83.3% for angle of jaw augmentation to 99.0% for improvement of acne scars. CONCLUSION: Bellafill is a safe and effective option for a semipermanent soft tissue filler, with high patient satisfaction and a good safety profile.

Il s'agit d'un produit de comblement de PMMA de troisième génération, dont les microsphères de PMMA, de formes et de dimensions plus uniformes, réduiraient l'incidence de granulomes. MÉTHODOLOGIE: Les chercheurs ont procédé à une analyse rétrospective de leur expérience clinique du Bellafill utilisé comme produit de comblement injectable des tissus mous dans les scénarios cliniques suivants entre 2014 et 2017: sillons nasogéniens profonds, cicatrices déprimées d'acné facial, perte de volume de l'os malaire, émaciation des tempes, dépression du rebord orbital inférieur, augmentation du menton, augmentation de l'angle des mâchoires et augmentation des lèvres. Le résultat primaire était le taux de réactions indésirables et le résultat secondaire, la satisfaction subjective des patients. RÉSULTATS: Entre 2014 et 2017, les plasticiens ont injecté 842 seringues de Bellafill à 212 patients, pour un total de 417 interventions. De ce nombre, 96 (23,0 %) visaient des cicatrices d'acné, 82 (19,7 %), la restauration du volume de l'os malaire, 65 (15,6 %), l'augmentation des sillons nasogéniens, 45 (10,8 %), l'augmentation du menton, 42 (10,1 %), la restauration du volume du rebord orbital inférieur, 28 (6,7 %), la restauration du volume des tempes, 25 (6,0 %), les retouches des petites zones de dépression nasale après une rhinoplastie, 22 (5,3 %), l'augmentation des lèvres, 12 (2,9 %), l'augmentation de l'angle de la mâchoire. Chaque patient s'est fait injecter de une à 12 seringues, réparties entre une et trois séances. Six cas de réactions indésirables se sont produits (1,4 %), soit quatre cas de nodules solitaires au point d'injection, un cas cas d'œdème de la paupière inférieure qui a persisté trois mois et un cas d'œdème de la lèvre inférieure qui a disparu en quelques heures. Le taux de satisfaction des patients a oscillé entre 83,3 % pour l'augmentation de l'angle de la mâchoire et à 99,0 % pour l'atténuation des cicatrices d'acnén. CONCLUSION: Le Bellafill est un produit de comblement des tissus mous à la fois sécuritaire et efficace, qui suscite une satisfaction élevée de la part des patients et possède un bon profil d'innocuitfi.

Anterior Nasal Spine Relocation for Caudal Septal Deviation: A Case Series and Discussion of Common Scenarios.

BACKGROUND: Deviation of the anterior nasal spine (ANS) is a common cause of caudal nasal septal deviation. In our experience, relocation of the deviated ANS is a useful technique in the correction of the caudal septal deviation. OBJECTIVES: To describe our experience with the ANS relocation technique in isolation and in combination with other techniques for correction of caudal septal deviation. METHODS: A retrospective chart review was performed on cases of ANS relocation. RESULTS: A total of 378 patients underwent ANS relocation over 4 years. Complete straightening of the septum occurred in 312 cases (82.5%), and significant improvement with mild remnant deviation occurred in 66 cases (17.5%). No patients had severe remnant deviation. None of the patients requested for revision surgery. A total of 351 patients (92.9%) experienced significant subjective improvement in bilateral nasal airflow, while 27 patients (7.1%) experienced mild improvement in bilateral nasal airflow. None of the patients had worsened airflow after surgery. CONCLUSION: The ANS relocation technique is a useful and effective technique which can be used in isolation or in combination of other techniques for the correction of caudal septal deviation.

Digital imaging in rhinoplasty.

BACKGROUND: Imaging in facial plastic surgery is becoming common. With the advances of digital imaging software, modifications of preoperative images for rhinoplasty patients can help to predict outcomes. The primary objective of this study was to determine whether preoperative digital image modification in rhinoplasty patients is useful in predicting postoperative outcomes. METHODS: Patients undergoing rhinoplasty were prospectively collected and underwent preoperative digital imaging modifications using computer software. Postoperative images were compared to the preoperative modified images. Rankings for similarity were performed by patients and surgeons. Wilcoxon ranked-pairs test was used to compare the groups with a predetermined P value of 0.05, and levels of agreement were assessed using weighted kappa scores. RESULTS: One hundred twelve patients were collected and postoperative images were taken 11 months after surgery (range = 6-30 months). Frontal images were rated as poor, average, very close, or identical by patients 6.2, 52.7, 33.0, and 8.0%, and by surgeons 2.7, 61.6, 34.8, and 0.9%, respectively (Wilcoxon test, P = 0.23). Lateral images were rated as poor, average, very close, or identical by patients 1.8, 18.8, 48.2, and 31.3%, and by surgeons 0.9, 24.1, 59.8, and 15.2%, respectively (Wilcoxon test, P = 0.0024). Weighted kappa scores for agreement were 0.42 for frontal views of patients and surgeons and 0.65 for lateral views. CONCLUSION: Ratings by patients and surgeons comparing preoperative manipulated images with postoperative outcomes are predictive in approximately 75% of the patients, and lateral images are more useful for this goal. Level of agreement between patient and surgeon scoring is good for lateral images and moderate for frontal.

[Correlation between subjective assessment and objective measurement of nasal obstruction].

OBJECTIVE: To investigate the correlation between subjective assessment from clinician and patients and the objective measurement from active posterior rhinomanometry and acoustic rhinometry. METHODS: Clinician and patients' assessment of nasal patency was achieved by visual analogue scale (VAS). Objective measurement included active posterior rhinomanometry and acoustic rhinometry. The mean of clinician's assessment and patients' VAS was compared by using paired-samples t-test. The correlation between unilateral nasal airflow resistance and unilateral nasal airway volume, unilateral minimal cross section area, and also subjective assessment and objective measurement of nasal patency were analysed by using Spearman correlation analysis in total patients. RESULTS: In total of 316 patients, pre-decongestion and post-decongestion, unilateral nasal airflow resistance and unilateral nasal airway volume, unilateral minimal cross section area had significant negative correlation respectively (P = 0.000). The mean of clinician's assessment and patients' VAS had significant difference (P < 0.001) before and after decongestion. Clinician's assessment had significant positive correlation with patients' VAS, nasal airflow resistance, and significant negative correlation with nasal airway volume, minimal cross section area of nasal cavity before and after decongestion (P = 0.000). Patients' VAS had significant positive correlation with nasal airflow resistance, and significant negative correlation with nasal airway volume, minimal cross section area of nasal cavity before and after decongestion (P = 0.000). The correlation coefficients from clinician's assessment and objective measurements were greater than those from patients VAS and objective measurements. CONCLUSIONS: The parameter of active posterior rhinomanometry had significant negative correlation with the parameters of acoustic rhinometry. Clinician assessment of nasal patency had significant positive correlation with patients' VAS; both of them had significant correlation with the parameters of rhinomanometry and acoustic rhinometry. Clinician's assessment was more objective and reliable to the parameters of objective measurement than patients' VAS.

Nasal airway volume and resistance to airflow.

BACKGROUND: In modern rhinological practice and research, rhinomanometry and acoustic rhinometry are widely used. The goal of this study was to determine whether there is correlation between rhinomanometrically derived nasal airflow resistances and acoustic rhinometrically derived nasal airway volumes. METHODS: To achieve the goal, a prospective cross-sectional study of a total of 316 patients complaining of nasal obstruction was performed. Resulting data were compared by means of Spearman rank correlations of the total number of patients and of subgroups. RESULTS: The total number of patients, and most subgroups, in both their untreated and decongested states showed significant negative correlation unilaterally between nasal airflow resistances and nasal volumes. CONCLUSION: Rhinomanometric nasal airflow resistances and concurrent acoustic rhinometric nasal airway volumes are closely correlated. The combination of the two objective methods provides insight into nasal airflow physiology and nasal airway anatomy.

Transfixion incision as an initial technique in nasal tip deprojection.

BACKGROUND: The overprojected nasal tip presents a significant challenge to the surgeon performing rhinoplasty. Full transfixion incision as a means of dealing with this deformity has been studied only in combination with other surgical methods. OBJECTIVES: To determine whether transfixion incision alone would result in significant nasal tip deprojection, and if skin thickness had an effect on the extent of deprojection the procedure yielded. METHOD: Seventy-two consecutive patients with an aesthetic goal of nasal tip deprojection were enrolled. The sole surgical means of deprojection used was transfixion incision. Subjects were categorized as thin-, medium- or thick-skinned based on the surgeon's analysis. These groups were compared in terms of their postprocedural nasal tip deprojection. RESULTS: Using transfixion incision as the sole means of correcting this deformity resulted in a mean nasal tip deprojection of 1.6 mm (ranging from 0 mm to 3 mm). Patients in the thin skin group had a mean deprojection of 2.12 mm. This was significantly greater than for both the medium- and thick-skinned groups. There was no significant difference between the medium- and thick-skinned groups. CONCLUSIONS: Surgeons may use skin thickness when planning interventions for correcting nasal tip overprojection. When used alone, transfixion incision resulted in tip deprojection comparable with that achieved when combined with other methods, particularly for thin-skinned patients. Surgeons can thus use a graduated approach in which transfixion incision, the least destructive method, is used before proceeding with other interventions.
