Cohort Data

Bilateral choanal atresia (CA) is a rare congenital malformation frequently associated with other anomalies. CHARGE association is closely linked to bilateral CA. The aim of this study was to describe the outcomes of the endoscopic repair in bilateral CA, and to assess the role of postoperative nasal stenting in two cohorts of CHARGE-associated and non-syndromic CA. Thirty-nine children were retrospectively analyzed (16 patients had CHARGE-associated CA). The rate of postoperative neochoanal restenosis was 31.3% in the CHARGE population, and 47.8% in the non-syndromic CA cohort. Data on postoperative synechiae and granulation tissue formation, need for endonasal toilette and dilation procedures, and number of procedures per patient were presented. Stent positioning led to a higher number of postoperative dilation procedures per patient in the non-syndromic cohort (p = 0.018), and to a higher rate of restenosis both in the CHARGE-associated, and non-syndromic CA populations. Children with CHARGE-associated and non-syndromic bilateral CA benefitted from endonasal endoscopic CA correction. The postoperative application of an endonasal stent should be carefully evaluated.

Purpose To investigate the therapeutic effect of local photothermal (PT) heating on suppression of stent-induced granulation tissue formation in mouse colon. Materials and methods A gold nanoparticle (GNP)-coated self-expandable metallic stent (SEMS) was prepared using a two-step synthesis process for local PT heating under near-infrared laser irradiation. Twenty-four mice were randomly divided into two groups of 12 and subjected to SEMS placement in the colon. Group A received a GNP-coated SEMS without local heating and Group B received a GNP-coated SEMS and underwent local heating at 55°C after SEMS placement. The therapeutic effect of local heating was assessed by comparing the histopathological, immunohistochemical, and endoscopic results. Results Four mice were excluded because of stent migration (n = 3, group B) or death (n = 1, group A). Stent-induced granulation tissue-related variables were significantly lower in group B than in group A (p < 0.001). In vivo endoscopic images, 4 weeks after stent placement, showed granulation tissue formation over the wire mesh in group A and relatively good patency of the stented colon with no definite irregularities in group B. There was more vascular endothelial growth factor (VEGF) positivity in group A than in group B. Conclusion Local PT heating suppresses granulation tissue formation after stent placement in mouse colon.

Objectives: Transoral laser surgery for glottic stenosis (transverse cordotomy and anteromedial arytenoidectomy (TCAMA)) is often complicated by granulation tissue (GT) formation. GT can cause dyspnea and may require surgical removal to alleviate airway obstruction. Inhaled corticosteroids (ICS) have been shown to reduce benign vocal fold granulomas, however its use to prevent GT formation has not been described. We aimed to analyze the effect of immediate postoperative ICS on GT formation in patients undergoing transoral laser surgery for glottic stenosis. Methods: A retrospective analysis of patients that had transoral laser surgery for glottic stenosis from 2000 to 2019 was conducted. Surgical instances were grouped into those that received postoperative ICS and those that did not. Demographics, diagnosis, comorbidities, intraoperative adjuvant therapy, and perioperative medications were collected. Differences in GT formation and need for surgical removal were compared between groups. A multivariate exact logistic regression model was performed. Results: Forty-four patients were included; 16 required 2 glottic airway surgeries (60 surgical instances). Of the 23 instances where patients received immediate postoperative ICS, 0 patients developed GT; and of the 37 instances that did not receive postoperative ICS, 15 (40.5%) developed GT ( P < .0001). Eight (53.3%) of these cases returned to the OR for GT removal. ICS use was solely associated with the absence of GT formation ( P = .042) in the multivariate analysis. Conclusions: Immediate postoperative use of ICS seems to be a safe and effective method to prevent granulation tissue formation and subsequent surgery in patients following transoral laser airway surgery for glottic stenosis.

Background. A dry socket also referred to as alveolar osteitis (AO) is a common postoperative complication following tooth extraction, due to the disruption of the clot within the wound. This study aimed to evaluate the efficacy of concentrated growth factor (CGF) in the healing of alveolar osteitis following tooth extraction. Methods. The study was conducted at University Dental Hospital Sharjah, UAE. Patients undergoing tooth extraction at the oral surgery clinic were advised to return immediately if they suffer from pain. Over the following first week after tooth extraction, patients who reported pain symptoms were recalled and all dry sockets were identified. The patients were divided into two groups. Group I patients received conventional treatment with socket curettage and saline irrigation only, while in group II CGF was inserted into the socket. Both groups were observed for pain score and quantification of granulation tissue formation. Results. A total of 40 dry socket patients, aged between 18 and 60 years, from a total of 1,250 patients, were included in the study. 30 patients were given conventional treatment while another 10 patients were given CGF. Patients who received CGF had a pain score of 7–10 at presentation, and the pain score dropped to 0–3 on day 4 and further improved to 0-1 on day 7 (p=0.001). Granulation tissue formation appeared in the conventional group I on day 7 while the CGF group II showed earlier granulation tissue formation by day 4 (p=0.001). The posttreatment pain score is inversely proportional to the amount and rate of granulation tissue formation in the socket. Conclusion. The study suggests that delivery of CGF into a dry socket helps relieve pain and expedite the wound healing process as shown by a statistically much lower pain score and earlier and more rapid formation of granulation tissue when compared to the conventional alveolar osteitis therapy.

Wound healing is a complex physiological process consisting of four phases: coagulation, inflammation, proliferation and migration, and remodeling, each with distinct characteristics. Studies have suggested that mangosteen pericarp extract (MPE) may accelerate wound healing. However, the mechanism has not been fully understood. This study aims to evaluate the effect of MPE cream in various concentrations in acute wound healing of albino mice, both histologically and macroscopically. Thirty-two healthy female Swiss albino mice, aged 6-9 weeks, weight 20-30 g, were included in this study. The samples were randomly divided into eight groups each consisting of 4 mice. The first four groups were treated with MPE cream 5%, 10%, and 20%, and no medication (control group), respectively, and were sacrificed after three days. The other four groups received the same application and were sacrificed after 8 days. Wound bed diameter was measured and biopsy from the skin lesion was performed for histopathologic examination. Mann-Whitney test was used to analyze the diameter of the wound bed and histopathological findings of granulation tissue formation, reepithelialization, and inflammation, with P<0.05 considered as significant. MPE cream significantly improved wound healing by increasing granulation tissue formation, and reepithelialization. In addition, MPE cream application was also shown to decrease the number of inflammatory cells, particularly in 5% and 10% concentrations, both in the 3-day and 8-day groups. MPE cream application can accelerate wound healing and thus can be used in acute wound treatment.

Airway Stenosis

Introduction: Sequelae of chronic foreign body aspiration include occlusive granulation tissue formation, which can cause delayed fixed airway stenosis. The aim of this study is to highlight this complication, which should be diagnosed early and treated proactively. Methods: We present a case series of areca nut aspiration, an organic foreign body commonly chewed in Southeast Asia, complicated by delayed airway stenosis and examine the peculiar nature of areca nut that predisposes to this complication. Results: Long-term sequelae of areca nut aspiration are granulation tissue formation, potentially complicated by airway stenosis due to the mechanical and chemical irritant nature of areca nut. Discussion: Organic impacted foreign bodies such as areca nut can cause delayed complications of airway stenosis. Both the sharp edges of the areca nut and chemical irritation caused by alkaloids released by the nut in constant contact with the airway mucosa can predispose to this long-term complication. Early diagnosis and appropriate therapeutic interventions such as balloon bronchoplasty can help restore airway patency and prevent lung damage.
