Restoring Severely Atrophic Edentulous Ridge of Mandible Using Self-Expanding Tissue Expander-A Case Report.

This report describes the use of Self Inflating Tissue Expanders (SITEs) to rehabilitate severely atrophic edentulous mandibular ridges, enabling successful bone grafting and implant placement. The treatment resulted in stable and complication-free implants over a seven-year follow-up, demonstrating SITEs' effectiveness in providing sufficient bone volume and soft tissue coverage for dental implants.

Sleep quality correlates with effectiveness of ultrapulse fractional CO2 laser in the treatment of facial atrophic acne scars.

Ultrapulse fractional CO2 laser is effective for acne atrophic scars. Whether this effectiveness is affected by sleep quality remains unclear. Aiming to investigate the relationship between sleep quality and postoperative effectiveness, a retrospective clinical study was conducted, enrolling 83 patients with atrophic acne scar. Sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI) questionnaire at 3 months after the end of the first treatment. The ECCA (échelle d'évaluation clinique des cicatrices d'acné) scale was used to evaluate the clinical effectiveness before and at 3 months after treatment. The patients were divided into a mild to moderate improvement group and a good to excellent improvement group, based on whether they achieved a 50% ECCA improvement rate. PSQI score was higher in the mild and moderate improvement group than in the good to excellent improvement group (7.6 ± 4.5 vs 3.8 ± 1.7, p < 0.001). Multivariate logistic regression showed that both PSQI score (odds ratio = 0.6 [95% CI = 0.5-0.8], p < 0.001) and scar type were correlated with postfractional CO2 laser effectiveness. Pearson correlation analysis suggested that PSQI score was negatively correlated with ECCA decline score (r = -0.6139, p < 0.0001). Receiver operating characteristic curve analysis showed that PSQI score (area under the curve = 0.759) and scar type (area under the curve = 0.737) were all closely correlated with postoperative effectiveness, without statistical difference between their accuracies (p = 0.647). Decision curve analysis demonstrated that both PSQI score and scar type correlated with postoperative effectiveness. Our results demonstrated that sleep quality correlates with the postoperative effectiveness of ultrapulse fractional CO2 laser in the treatment of atrophic acne scars.

Quantitative Evaluation of Vocal Bowing Following Bilateral Thyroplasty in Age-Related Vocal Atrophy.

OBJECTIVE: Age-related vocal atrophy (ARVA) is associated with vocal fold bowing, persistent glottal gap during phonation, and dysphonia. Bilateral medialization thyroplasty is sometimes performed in patients with ARVA to improve vocal fold closure and voice. We set out to quantify stroboscopic changes in vocal fold bowing, glottal closure, and abduction angle following bilateral thyroplasty and determine how these changes affect voice quality among patients with ARVA. METHODS: Fifteen individuals with ARVA who underwent bilateral medialization thyroplasty were included in this study. Two independent investigators calculated bowing index (BI), normalized glottal gap area (NGGA), and maximum abduction angle from laryngostroboscopic exams using ImageJ™. Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) and patient-reported measures were collected before and after thyroplasty. RESULTS: Thyroplasty resulted in a 10-point improvement in overall CAPE-V (Mean dif -10; 95% CI -17, -3.3, p < 0.01) and VHI-10 (mean dif -3.8; 95% CI -9.8, 2.3, p = 0.19, n = 8). NGGA and BI significantly decreased following surgery (mean dif -78; 95% CI -155, -1.5, p = 0.05; and mean dif -2.1; 95% CI -2.4, -0.84, p < 0.01, respectively). BI correlated with CAPE-V scores (r = 0.66, 95% CI 0.22, 0.87, p < 0.01). When considering the normalized combined contributions of both NGGA and BI, there was a stronger correlation in CAPE-V scores (r = 0.87, 95% CI 0.50, 0.97, p < 0.01) compared with either measure alone. CONCLUSIONS: Thyroplasty resulted in a decrease in vocal fold bowing, glottal gap area, and CAPE-V scores in patients with ARVA. Correction of vocal bowing and glottal gap, following bilateral thyroplasty, improved voice measures following surgery. Quantitative evaluation of vocal fold morphology may be valuable when assessing the severity and treatment-response in patients with ARVA following bilateral thyroplasty.

The Custom Alveolar Ridge Splitting (CARS) Technique for Predictable Horizontal Ridge Augmentation in the Atrophic Posterior Mandible: A Case Report.

The Custom Alveolar Ridge Splitting (CARS) technique was recently reported as a less-invasive treatment option for augmentation of the maxillary anterior area in cases where alveolar width deficiency exists due to bone resorption and remodeling. This technique creates an intraosseous defect to improve success when horizontal ridge augmentation is attempted. The purpose of the present case report was to demonstrate implant placement in an atrophic posterior mandibular site using the CARS technique. This technique was used in the mandibular right second premolar area, followed by placement of a single implant. The restored implant showed stable soft and hard tissue outcomes at 6 months postloading.

Reconstruction of Moderately and Severely Atrophic Scalp-A Multicentric Experience in Surgical Treatment of Patients Irradiated for Tinea Capitis in Childhood and Surgical Algorithm.

Background and Objectives: Before the introduction of griseofluvin, the use of X-ray radiation was the treatment of choice for tinea capitis. More than half a century later various types of tumors have been found to be associated with childhood irradiation due to tinea capitis, most commonly cancers of the head and neck, as well as brain tumors. The often unusually aggressive and recurrent nature of these tumors necessitates the need for repeated surgeries, while the atrophic skin with an impaired vascular supply due to radiation often poses an additional challenge for defect reconstruction. We present our experience in the surgical treatment of such patients. Materials and Methods: This is a retrospective cohort study. In this study, 37 patients treated for acquired defects of the scalp with a history of irradiation therapy due to tinea capitis in childhood were included in this study, 24 male and 13 female patients. The mean age at the first appointment was 60.6 ± 7.8, with the youngest included patient being 46 and the oldest being 75 years old. Patients' characteristics, surgical treatment, and complications were analyzed and a reconstructive algorithm was developed. Results: Local flaps were used for reconstruction in 34 patients, direct sutures were used in 10 patients and 20 patients received split-thickness skin grafts for coverage of both primary and secondary defects for reconstruction of flap donor sites. One regional flap and one dermal substitute covered by an autologous skin graft were also used for reconstruction. Complications occurred in 43.2% of patients and were significantly associated with the presence of comorbidities (p = 0.001), aseptic bone necrosis (p = 0.001), as well as skin atrophy in frontal, occipital, and parietal region (p = 0.001, p = 0.042 and p = 0.001, respectively). A significant correlation between major complications and moderate skin atrophy was found only in the parietal region (p = 0.026). Conclusions: Unfortunately, many protocols developed for scalp reconstruction are not applicable in the setting of severe or diffuse scalp skin atrophy associated with high tumor recurrence rate and radiation-induced vascular impairment, such as in tinea capitis patients in Serbia. An algorithm has been developed based on the authors' experience in managing these patients.

Buccally or Lingually Tilted Implants in the Lateral Atrophic Mandible: A Three-Year Follow-Up Study Focused on Neurosensory Impairment, Soft-Tissue-Related Impaction and Quality of Life Improvement.

Background and Objectives: In the severely resorbed posterior mandible, implant placement requires either bone regenerative procedures, subperiosteal implants or short implant placement with drawbacks including morbidity and increased treatment costs and duration. To overcome these inconveniences, some unconventional alternatives have been suggested, such as buccally or lingually tilted implants in the lateral mandible, bypassing the inferior alveolar nerve. The aim of the present retrospective study was to evaluate the three-year survival rate of implants inserted in the posterior atrophic mandible, bypassing the inferior alveolar nerve. The assessment was focused on the occurrence of postoperative complications related to neurosensory impairment and soft tissue impaction, as well as overall improvement in quality of life. Materials and Methods: Patients with severe bone atrophy in the lateral area of the mandible were included in the present study. Only the implants tilted either buccally or lingually to bypass the inferior alveolar nerve were analysed. The relation between peri-implant soft tissue and the healing abutment was assessed and a secondary revision surgery was performed when indicated. The Semmes-Weinstein pressure neurological test was used for qualitative assessment of inferior alveolar nerve function and the Geriatric Oral Health Assessment Index (GOHAI) was used for evaluating Oral-Health-Related Quality of Life (OHRQoL). Results: Fourteen implants were placed in nine patients during the evaluation period. Survival rate was 100%, temporary paraesthesia occurred in one patient and a limited definitive paraesthesia was seen in another patient. Mild or significant discomfort related to soft tissue impaction with healing abutment was observed in six out of nine patients. A statistically significant OHRQoL improvement was observed in all patients. Conclusions: Despite the limited number of patients and observation time, insertion of implants buccally or lingually bypassing the inferior alveolar nerve is a predictive treatment option for patients with severe bone atrophy in the posterior mandible.

Artificial Urinary Sphincter Cuff Downsizing Improves Continence and Patient Satisfaction in Cases of Sub-cuff Atrophy.

PURPOSE: The management of artificial urinary sphincter sub-cuff atrophy remains controversial, and clinical outcomes are underreported. We intend to examine the impact of cuff downsizing in cases of isolated sub-cuff atrophy. MATERIALS AND METHODS: We reviewed our prospectively collected, institutionally approved quality improvement database for this study from 2011 to 2022. Institutional Review Board approval was obtained for the analysis. Sub-cuff atrophy in patients with post-prostatectomy incontinence was diagnosed with a clinical presentation of recurrent urinary leakage, serial pelvic films, cystoscopy, and patient evaluation. Outcomes were assessed with pad use, subjective measures, and American Urological Association Symptom Score scores. RESULTS: During the study interval, 871 encounters for artificial urinary sphincter placement were identified, 229 for revision or replacement, of which cuff downsizing for isolated cases of sub-cuff atrophy occurred in 34. Downsizing took place after a median of 6.5 years after initial artificial urinary sphincter placement. Of the patients, 97% reported subjective improvement and 93% experienced a decrease in daily incontinence pad use, with a mean±SD decrease of 2.2±1.45 pads (P < .01). American Urological Association Symptom Score bother scores decreased from pre-downsizing values by a mean±SD of 1.5±1.4 (P = .01). After a median follow-up of 1.8 years after downsizing, 24 (70.6%) of downsized cuffs remained in place, 2 (5.9%) were further downsized, 2 (5.9%) required replacement for mechanical failure, 4 (11.8%) underwent removal for erosion, and 2 (5.9%) underwent replacement for a herniated pressure regulating balloon. CONCLUSIONS: When diagnosed using objective criteria, cuff downsizing improves continence and patient satisfaction in cases of sub-cuff atrophy.

Osteoperiosteal decortication and bone grafting combined with wave plating for femoral shaft aseptic atrophic nonunion after intramedullary nailing.

OBJECTIVE: Femoral shaft nonunion after intramedullary nailing fixation remains a challenge for orthopedic surgeons. This study evaluated osteoperiosteal decortication and iliac bone grafting combined with wave plating as a treatment for aseptic atrophic nonunion of the femoral shaft after intramedullary nailing. METHODS: The study included 22 patients (two female, 20 male; mean age 40.8 years [range, 19-61]) with aseptic atrophic nonunion of the femoral shaft who underwent osteoperiosteal decortication and iliac bone grafting combined with wave plating between January 2016 and January 2020. Cases with infected nonunion, hypertrophic nonunion, and nonunion after plate osteosynthesis were excluded. Clinical outcomes were assessed retrospectively using the Samantha X-ray and Paley scale scores. RESULTS: The mean follow-up period was 18.8 months (range, 12-35). Bone union was achieved in all patients. The average clinical healing time was 5.7 months (range, 3-14). The mean Samantha X-ray score was 5.7 ± 0.45 and the Paley scores indicated excellent or good clinical results in all cases. One patient developed sterile wound leakage that resolved after a dressing change. CONCLUSIONS: Osteoperiosteal decortication and bone grafting combined with wave plating is an excellent treatment for aseptic atrophic nonunion of the femoral shaft after intramedullary nailing.

Transcorporal Artificial Urinary Sphincter Cuff Placement in a Case Requiring Revision for Urethral Atrophy.

Artificial urethral sphincter (AUS) implantation is the definitive management of male stress urinary incontinence (SUI). Under the long-term pressure of the cuff, recurrence of incontinence caused by urethral atrophy can always be observed in patients. In this situation, distal cuff locations are needed, and new cuff sites should be sought in patients who need to undergo AUS reimplantations. Meanwhile, the circumference of the more distal urethra is often too small to fit with a 4.0 cm cuff. This means that the bulk of the urethra should be added not only for a sufficient urethral circumference but also for better protection. Here, we report a case that required AUS reimplantation because of urethral atrophy. This 73-year-old man had undergone AUS implantation 7 years ago and developed incontinence in the past 3 months. Physical examination and ultrasonography determined that the device still worked, and no obstruction or injury was observed through cystoscopy. Surgery for revision of the AUS was needed. In this operation, a new cuff was implanted transcorporally, which was 2 to 3 cm distal to the original cuff site. During a 6 month short-term follow-up, no stress incontinence, urethral injury, or dysuria was observed. The transcorporal technique offers significant advantages in patients with urethral atrophy: corporal tunica albuginea is added to the urethra, allowing a suitable cuff size and lower risk of erosion. It is worth recommending in the reoperation of AUS implantation.

Soft-Tissue Reconstruction in Progressive Hemifacial Atrophy: Current Evidence and Future Directions.

BACKGROUND: Progressive hemifacial atrophy is a rare disorder characterized by gradual unilateral soft-tissue atrophy in the face, which may also include clinically significant degeneration of underlying muscle and bone. In recent years, there has been a growing body of evidence regarding different soft-tissue reconstructive strategies in progressive hemifacial atrophy and the impact of intervention timing on disease progression. This article provides a comprehensive synthesis of the latest evidence to guide optimal management. METHODS: A comprehensive multidatabase search was performed through April of 2020 using relevant search terms to identify clinical studies. Outcomes, complications, and disease- and patient-related indications pertaining to different soft-tissue reconstructive strategies in progressive hemifacial atrophy were collected and critically appraised. RESULTS: Thirty-five articles reporting on a total of 824 progressive hemifacial atrophy patients were evaluated; 503 patients (61 percent) were managed by microvascular free flaps, 302 patients (37 percent) were managed by autologous fat grafts, and 19 patients (2 percent) were managed by pedicled flaps. A detailed synthesis of outcomes is presented in this article, as is a comparative evaluation of different microvascular free flap options. CONCLUSIONS: Soft-tissue reconstruction in progressive hemifacial atrophy remains an evolving field. Operative decision-making is often multifaceted, and guided by specific volumetric, aesthetic, and functional deficiencies. Serial fat grafting is the primary modality used for patients with mild soft-tissue atrophy, whereas microvascular free flaps widely remain the treatment of choice for reconstruction of large-volume defects. There exists a growing role of graft supplementation to improve fat graft survival, whereas recent evidence demonstrates that early intervention may help curb disease progression.

Autogenous bone grafting with conventional implants vs zygomatic implants for atrophic maxillae: a retrospective study of the oral health-related quality of life.

INTRODUCTION: Autogenous bone grafting (ABG)-combined or not with Le Fort I osteotomy (LFIO)-and zygomatic implants (ZI) are two reliable techniques for the fixed rehabilitation of atrophic maxillae. ZI allow a reduced treatment duration with no need to graft, immediate loading and in principle less morbidity. The aim of this retrospective study was to compare these two protocols on oral health-related quality of life (OHRQoL). We also discussed implant and prosthetic survival rates, and biological complications. MATERIAL AND METHODS: All patients who benefited from ZI or ABG with conventional implants (CI) for a fixed maxillary rehabilitation, from November 2011 to April 2019, were included: 21 patients in the ABG group and 22 in the ZI group. OHRQoL was evaluated postoperatively by OHIP-14 questionnaire. RESULTS: OHIP-14 median scores were respectively 6.5 (interquartile range [IQR] 2.0-13.0) and 6.0 (IQR 3.0-10.0) without significant difference (p = 0.97). Implant/prosthetic survival rates were 97.9%/100% and 97.1%/95.5%. Biological complications rates were 33.3% and 36.4% without significant difference (p = 0.83). DISCUSSION: The type of surgery or prosthesis does not seem to affect final OHRQoL, implant and prosthetic survival rates or biological complications rates.

Efficacy and adverse reactions of fractional CO2 laser for atrophic acne scars and related clinical factors: A retrospective study on 121 patients.

OBJECTIVE: This study was performed to analyze the efficacy, adverse reactions of fractional CO2  laser for atrophic acne scars, and related clinical factors. METHODS: The clinical data of 121 patients with atrophic acne scars treated with ultra-pulsed fractional CO2  laser in the Cosmetic Dermatology from August 2014 to March 2020 were retrospectively analyzed. The efficacy and adverse reactions of atrophic acne scar after fractional CO2  laser therapy were statistically analyzed. The clinical factors related to efficacy and adverse reactions after the first therapy session were analyzed by multivariate logistic regression. RESULTS: A total of 121 patients received 206 sessions of fractional CO2  laser therapy, with an average of 1.7 sessions. Moderate to excellent improvement rate reached 50.4% after the first session. Multivariate logistic regression analysis indicated that rolling scars responded better to fractional CO2  laser treatment than icepick scars (OR = 7.3, 95% CI [1.2, 43.4], p = 0.029), and scar improvement was more significant in the high-energy laser group than in the low-energy laser group (OR = 10.9, 95% CI [1.1, 106.8], p = 0.041). The main adverse reactions after fractional laser surgery were pigmentation, skin sensitivity, persistent erythema, and acneiform eruption. Multivariate logistic analysis revealed that the longer the scar duration, the higher incidence of postoperative adverse reactions (OR = 1.3, 95% CI [1.1, 1.5], p = 0.008). Compared with icepick scars, rolling scars (OR = 10.4, 95% CI [2.3, 47.7], p = 0.003) and boxcar scars (OR = 12.0, 95% CI [3.3, 44.0], p < 0.001) had higher risk of developing adverse reactions. The incidence of postoperative adverse reactions was also higher in the combined mode group (DeepFX mode + ActiveFX mode) than in the single-mode group (OR = 7.8, 95% CI [2.4, 25.5], p < 0.001). CONCLUSION: Fractional CO2 laser was effective in the treatment of atrophic acne scars, without serious adverse reactions. Scar type and laser energy were independent clinical factors affecting its efficacy. Scar course, scar type, and fractional laser mode were independent clinical factors affecting its adverse reactions.

Additively Manufactured Lattice-like Subperiosteal Implants for Rehabilitation of the Severely Atrophic Ridge.

Subperiosteal implants represent an alternative implant approach for cases with severe bone atrophy. Although some successful clinical cases have been reported, the biomechanical stability of subperiosteal implants remains unclear, and more data are needed to confirm the feasibility of this approach. Therefore, this study investigated the biomechanical characteristics of subperiosteal implants based on histological observation, clinical cases, and finite element analysis. Finite element analysis indicated that subperiosteal implants with a lattice-like structure could better disperse the stress to the underlying bone surface. A novel customized subperiosteal implant was then digitally designed and fabricated using an additive manufacturing technology. Six beagle dogs received such customized subperiosteal implants. Histological and microcomputed tomography examination showed new bone growth into and around the implant. Patient-specific subperiosteal implants were placed into the edentulous mandibular bone, with immediate loading. The implant was functional, without pain or infection, over a 12 month observation period. Images taken 12 months post-operatively showed new bone formation and osseointegration of the device. This indicated that 3D-printed lattice-like subperiosteal implants have sufficient stability for the rehabilitation of severely atrophic ridges.

Managing the severely atrophic maxilla: Farewell to zygomatic implants and extensive augmentations?

BACKGROUND: Dental rehabilitation of severe atrophic upper jaws remains challenging. A new generation of subperiosteally placed and rigid multi-vector bone-anchored patient-specific implants proposes an innovative line extension in implant dentistry. This single-center retrospective study focused on treating severely atrophic maxillae using these implants. METHODS: All patients who were treated with a patient-specific implant (IPS Implant® Preprosthetic, KLS-Martin, Tuttlingen, Germany) at Hannover Medical School due to severe atrophy of the maxilla who had no history of malignancy, cleft lip or palate, or trauma were evaluated regarding implant stability and prosthetic restoration, as well as complications. RESULTS: Out of a total of 58 inserted implants, 13 implants in 10 patients, which were placed to treat a severely atrophic upper jaw, were identified. The mean follow-up period was 8.2 months (1-29 months). All implants were clinically stable over the entire period. All patients with an observation period of over 2 months received prosthetics for restoration. Minor complications, screw fractures, infection, and exposure of the framework were observed, but these did not lead to failure. CONCLUSION: This initial follow-up suggests that this new generation of implants represents a valuable treatment alternative, especially for patients with a history of failed dental implant placement. Larger numbers of cases and longer observation periods are required to confirm our findings.

Immediate Rehabilitation of the Severely Atrophic Maxilla Using Trans-Sinus Nasal Protocol and Extended Length Subcrestal Angulated Implants. Case Series With 1-Year Follow-Up.

Immediate fixed full-arch rehabilitation of the severely atrophic maxilla eliminates use of a tissue-supported prosthesis during the healing phase and maximizes patient comfort and quality of life. The surgical treatment options available for immediate rehabilitation of the severely atrophic maxilla are dependent on the location and availability of the residual alveolar ridge. When bone is only available in the intercanine region, a graftless approach using tilted distal implants may not provide adequate distance between implants for favorable biomechanics. Subsequently, zygomatic implants are the alternative to provide adequate posterior occlusal support. Use of extended length subcrestal angulated implants offers an additional implant option for the clinician to restore the severely atrophic maxilla immediately. The treatment protocol involves anchorage of the implant fixture to the lateral wall of the nasal bone. The distally tilted implant transverses an augmented sinus cavity and extends to the site of the first permanent molar. The novel implant subcrestal angulation and use of a multi-unit abutment promotes passivity of fit of a full-arch fixed immediate prosthesis. Five clinical case reports from private practice are presented that outline the clinical value of the novel implant design in the rehabilitation of the severely atrophic maxilla. In each case, the use of zygomatic implants would be the only alternative to provide an immediate fixed prosthesis due to the absence of residual alveolar bone in the maxilla premolar and molar regions. The use of extended-length subcrestal angulated (ELSA) implants with straight or angulated multiunit abutments have successfully restored the maxillary arch immediately.

Modified Two-Stage Split Technique for Controlled Ridge Augmentation in Horizontally Atrophic Posterior Mandible: the First Stage of Research.

Various bone grafting methods are applied to eliminate horizontal atrophy of the jaws. However, problem complexity brings about ongoing research and development of new ways to achieve the predicted stable and long-term results of implantological treatment. The aim of the study was to evaluate the results of the developed method for bone grafting, a modified two-stage split technique for controlled ridge augmentation in horizontally atrophic posterior mandible, using radiological analysis data. MATERIALS AND METHODS: The study group included 18 patients with horizontally atrophic posterior mandible. According to cone beam computed tomography, 39 jaw segments were assessed before plastic surgery and after applying the two-stage split-crest technique for controlled ridge augmentation. The alveolar ridge width was estimated in the area of its top and at a distance of 1, 3, 5 mm from it using the vector of future implant position and taking into account the angle of inclination of the atrophic region of the mandible. RESULTS: When analyzing edentulous areas in the posterior mandible before treatment, there was rather a large angle of lingual inclination of the alveolar ridge. After 6 months, the average increase in bone tissue width in the region of the alveolar ridge top was 82%, it was 50.6% at a height of 1 mm from the top of the crest, 58.8% at 3 mm height, 46.7% at 5 mm (p≤0.05). Certain patterns of bone tissue growth were revealed depending on the structure of the reconstructed area. The most significant results were obtained in the molar segments of the mandible. CONCLUSION: The developed modified two-stage split technique for alveolar ridge augmentation allows achieving the required volume of bone tissue in the posterior mandible for successful implant treatment.

Comparison of Fractional Picosecond 1064-nm Laser and Fractional Carbon Dioxide Laser for Treating Atrophic Acne Scars: A Randomized Split-Face Trial.

BACKGROUND: To date, no studies have compared the fractional picosecond 1064-nm laser (FxPico) and fractional carbon dioxide laser (FxCO2) for the treatment of acne scars. OBJECTIVE: To compare the efficacy and safety between FxPico and FxCO2 for treating facial atrophic acne scars. MATERIALS AND METHODS: Twenty-five Asian patients with mild to moderate atrophic acne scars underwent single sessions of randomized split-face treatment with FxPico and FxCO2. Clinical efficacy was assessed by photographs, skin imaging analysis, and patient satisfaction. The adverse events were recorded on every visit. Skin biopsies were performed immediately and 3 months after treatment. RESULTS: The physician improvement scores for skin texture and atrophy significantly increased on the FxPico sides, but no significant difference was observed between FxPico and FxCO2. Skin imaging also showed significant improvement on both sides for scar volume. Postinflammatory hyperpigmentation (PIH) was not reported on FxPico sides, whereas 6 patients (24%) experienced mild PIH on FxCO2 sides. Immediate post-FxPico skin biopsy revealed laser-induced optical breakdown with photoacoustic columns. Collagen and elastic fibers increased at 3 months after both treatments. CONCLUSION: FxPico was as effective as FxCO2 in treating atrophic acne scars, correlating with evidence of tissue remodeling with more safety profiles.

Patient reported vaginal laxity, sexual function and stress incontinence improvement following vaginal rejuvenation with fractional carbon dioxide laser.

In this study, we have evaluated the efficiency of fractional carbon dioxide laser in the treatment of vaginal laxity and urinary incontinence. Thirty patients with vaginal laxity, sexual dysfunction and urinary incontinence complaints were treated with fractional carbon dioxide laser. Results were evaluated with patient questionnaires relating to comfort during the procedure and general satisfaction following the procedure. In the survey regarding comfort during the procedure, 90% (n:27) of the patients reported that they were comfortable during the procedure. The survey on the level of general satisfaction six months following the procedure revealed high-moderate level of satisfaction in 86% (n:26) of the patients. 66% (n:20) of the patients reported improved vaginal tightness and 63% (n:19) of the patients reported improvement in the quality of their sexual activity. Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire(PISQ-12) scores six months following the procedure were not significantly different when compared to the scores prior to the procedure. The average of Questionnaire for Urinary Incontinence Diagnosis(QUID) score prior to the procedure and six months following the procedure was 7.5 and 0.9 respectively (p < 0.05). Fractional carbon dioxide laser treatment results in high level of satisfaction and improvement in vaginal laxity, sexual dysfunction and urinary incontinence symptoms in patients with genitourinary syndrome.

Vocal Fold Fat Augmentation for Atrophy, Scarring, and Unilateral Paralysis: Long-term Functional Outcomes.

OBJECTIVE: There is a debate regarding the durability of fat implants. Our experience and recent publications suggest fat implantation may deliver a long-lasting improvement. This study aims to present the long-term outcomes for vocal fold fat augmentation using strict harvesting, preparing, and implantation protocols. STUDY DESIGN: A prospective cohort conducted between 2014 and 2020 (recruitment 2014-2017). SETTING: An academic tertiary referral center. SUBJECTS AND METHODS: Twenty-two patients with glottic insufficiency were enrolled: 11 had unilateral vocal fold paralysis (UVFP), and 11 had atrophy or scar. Harvested fat was injected unilaterally or bilaterally into multiple sites. Six of these patients also had simultaneous microlaryngoscopic removal of other benign glottic lesions. Outcome measurements included video stroboscopy; Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS) score; Voice Handicap Index (VHI); and acoustic analysis, performed preoperatively, 3, 12, 24, and 36 months after surgery. RESULTS: Ten augmentations were unilateral and 12 bilateral. Comparing the preoperative and 36-month postoperative periods, the mean VHI score improved from 73.45 (±22.78) to 44.88 (±28.93), P = .001, and the mean GRBAS decreased from 8.64 (±3.89) to 2.82 (±2.3), P = .001; 24 months postoperatively, the mean fundamental frequency decreased from 163.88 Hz (±41.61) to 150.44 Hz (±41.47), P = .012. Stroboscopic analysis revealed statistically significant improvement in mucosal wave propagation, phase closure, and phase symmetry. Best results were achieved in the UVFP subgroup. Computed tomography scans demonstrated long-term viability of the implanted adipose tissue. CONCLUSION: Fat is an excellent source of autologous graft. With careful patient selection and proper surgical technique, fat is suitable for long-term correction of glottic insufficiency. Fat augmentation should be considered as a long-lasting or even permanent solution, rather than temporary.
