Ambient solar-driven selenate reduction and removal from industrial brine using TiO2-based buoyant photocatalysts

Selenium (Se), released from mining, power generation, and agriculture, is an environmentally and ecologically concerning contaminant due to its toxicity at elevated concentrations. Se oxyanions are highly soluble and mobile in aquatic ecosystems, and have a strong tendency to bioaccumulate and biomagnify, leading to acute and chronic toxicity in animals and humans. Photocatalysis presents a promising sustainable Se treatment solution and has successfully reduced and removed Se from mining-influenced matrices using UV-powered slurry photoreactor systems. Despite its potential, active photocatalytic water treatment faces significant challenges, particularly high operating costs and limited development of scalable deployment strategies, which hinder its real-world application. Herein, we adapt photocatalytic Se reduction and removal towards an easily deployable solar-driven semi-passive application using TiO2-based buoyant photocatalysts (BPCs). The results demonstrate successful semi-passive photocatalytic selenium reduction and removal using BPCs under ambient solar conditions, achieving up to 99.6% removal of Se from an industrial brine matrix containing ∼3.5 mg/L of Se, despite challenges from dissolved oxygen and reactive oxygen species (ROS). We advance the mechanistic understanding of the ambient Se reduction pathway, successfully identifying Se(IV) as a reduction intermediate, and uncovering the role formic acid plays in suppressing the oxidative effects of ROS, enabling the complete reduction of Se. We address the major challenges to both Se treatment and environmental photocatalysis and highlight the potential of sustainable solar-driven and semi-passive photocatalytic processes to address environmental challenges like selenium.

Foreign bodies in the ear and nose of the Australian paediatric population: A standardised approach.

Foreign bodies (FBs) in the ears and noseare common presentations among paediatric patients, necessitating prompt and appropriate management to avoid potential complications. This article presents a standardised approach for FB retrieval based on local clinical data from a tertiary paediatric centre, addressing the challenges of identifying patients requiring specialist referral. The approach involves a detailed initial consultation and succinct examination todetermine the most suitable retrieval method. Patient preparation and equipment availability are key to successful outcomes. A combination of microsuction and alligator forceps with adequate illumination is strongly recommended, along with various adjunct tools commonly available. Urgent referral to otorhinolaryngology is indicated for button batteries and previous failed attempts. This comprehensive approach seeks to achieve successful FB removal and optimise patient outcomes in both community and hospital settings.

Mandibular Condylar Head Regeneration Owing to Remodeling of the Costochondral Graft After Condylectomy for Odontogenic Myxoma.

Odontogenic myxoma of the mandibular condyle is a rare tumor that requires complete surgical resection because of the tendency for recurrence. The right mandibular condyle was resected to remove the myxoma. The author performed immediate condylar reconstruction using a costochondral graft (CCG), and stable temporomandibular joint (TMJ) function and occlusion were achieved. During follow-up, the grafted CCG healed well, and a favorable bony union with the mandibular ramus was observed. Furthermore, unexpected bony remodeling was observed in the CCG; growth of the cartilaginous part resulted in the formation of a structure similar to the condylar head, and the body of the rib bone thickened similar to the mandibular subcondylar region. In conclusion, the author reported the successful removal of an odontogenic myxoma from the right mandibular condyle via condylectomy, condylar reconstruction using a CCG, and condylar head regeneration owing to CCG remodeling.

Endoscopic management of hernia repair fixing tacks embedded in the bladder wall: A case report

Background: Migration of fixing tacks into the bladder wall is a rare complication following laparoscopic hernia repairs. Case presentation: This report detailed an 80-year-old male who presented to the clinic with hematuria. Cystoscopy revealed a bladder calculus adherent to the bladder wall, with an underlying metallic tack. A stent snare was used to secure the edges of the tack, and a resectoscope loop was carefully used to resect and free it from surrounding mucosa. Conclusion: This was the first case report to describe the successful removal of a metallic fixing tack from the bladder through a transurethral approach in a patient post-hernia repair.

Diclofenac recovery by means of using Emulsion Liquid Membranes: A possible role of surfactant in the mass transfer process

Emulsion Liquid Membranes (ELM) are a useful method for drug extraction in aqueous solution, as they allow their recovery in a highly concentrated acceptor phase after passing through a membrane phase with a high surface area. The success of this process depends on system formulation and operation conditions. One of the most important aspects in the formulation is the addition of a surfactant that stabilizes the system, which can also participate in the mass transfer process. Recently, resistance to mass transfer caused by the use of polymeric surfactants, such as Abil® EM 90, has been reported. To verify this phenomenon observed in previous studies, the effect of various factors on the recovery of diclofenac (DCF) dissolved in an aqueous medium was analyzed using the ELM technique. The study concluded that using a membrane consisting of Abil® EM 90 (2 % w/V), trioctylamine (5 % w/V), and dodecane, along with a stripping phase formed by NaOH (0.10 mol/L), results in successful DCF removal. When emulsified at 15,000 rpm for 10 minutes at room temperature, it is possible to remove over 99 % of DCF after 15 minutes and recover 18.45 % after 30 min. Furthermore, it was determined that the action of the surfactant is the main cause of the resistance to the passage of DCF to the internal phase and its retention in the organic phase, as had already been observed. This is probably due to strong intermolecular interactions between Abil ® EM 90 and DCF and the formation of a complex and stable interfacial structure, similar to a hydrated bilayer, which favors the rigidity of the interface and keeps the drug trapped. A better understanding of the role surfactants play in the system is essential for the future design of more efficient and stable ELMs. This knowledge will enable the adaptation of the technology to a wider range of processes, including drug recovery. As a result, the maximum benefits of this technology can be fully realized.

Challenges in the diagnosis and management of soft tissue tumors of the oral cavity.

Soft tissue lesions are among the most prevalent forms of tumors or tumor-like alterations within the oral cavity. They exhibit a wide spectrum of characteristics, ranging from benign, noninvasive lesions to malignant tumors, which collectively present a diagnostic challenge. A 67-year-old patient presented with an incidental finding of induration on the right cheek during dental hygiene. The intraoral examination revealed a soft, non-tender swelling measuring 20 mm in diameter. The sensitivity and percussion tests for the teeth in the fourth quadrant yielded unremarkable results. Panoramic radiography (OPG) revealed tip-ping of the premolars and an unclear apical finding in region 44. Cone-beam computed tomography (CBCT) revealed a sharply defined, lobulated hypodense lesion in the right buccal area. To clarify the diagnosis and optimize perioperative management, a 3 Tesla dental magnetic resonance imaging (MRI) scan was performed. This identified a 23×6×23 mm lipoma along the right mandibular ramus, causing detachment of the buccinator and de-pressor anguli oris muscles. A cinematic rendering reconstruction derived from the MRI data facilitated enhanced visualization for preoperative planning. The surgical excision was performed under local anesthesia, resulting in the successful removal of the neoplasm while preserving the mental nerve and submandibular gland. Histo-pathology confirmed the presence of a lobulated mature cell lipoma. The patient exhibited no complications during the removal of the sutures, with complete wound healing and no recurrence observed. This article highlights the efficacy of advanced MRI diagnostics and post-processing techniques in the management of ambiguous soft tissue neoplasms.

Effective capture of As(V) from water by a facile one step hydrothermal synthesized of 2-D bismuthene quantum dots nanosorbent

Arsenic species have been known for their toxic impact on human. Therefore, removal of such pollutant requires efficient and effective removal methodology from polluted water. In this study, bismuthene quantum dots (Bi-ene-QDs) were fabricated by a green and facile one pot-hydrothermal conversion reaction of Bi(NO3)3·5H2O. Bi-ene-QDs exhibited semi-spherical crystalline providing 6.0 nm 157.78 m2/g. Consequently, As(V) capturing by Bi-ene-QDs revealed optimum practical conditions at pH 3, interaction duration time 40 min and 10 mg Bi-ene-QDs dosage. The interaction of As(V) ions with Bi-ene-QDs were confirmed by the appearance of As-O stretching vibration. Moreover, Bi-ene-QDs achieved excellent adsorptive capture percentages of Arsenic ions from sea, tap and wastewater providing 94.61, 95.21 and 94.38% from contaminated samples with 5 mg L−1 Arsenic ions. Therefore, Bi-ene-QDs can be categorized as an unprecedented and efficient nanosorbent for the successful removal of Arsenic ions pollution from various wastewater matrices with > 90.0% efficiency.

Successful Subungual Glomus Tumor Removal: A Case Report and Future Guidance on Diagnosis and Treatment

Background: Glomus tumors are rare benign hamartomas of the glomus body that occur mostly – though not limited to - the distal phalanxes of the digits. This article provides a real-life example of successful rare disease identification and treatment. It also provides a guideline that may help serve as future guidance on diagnosis and treatment. Case: A 41-year-old male came to our hospital presenting with a chief complaint of episodes of throbbing pain, which occurred spontaneously on the left thumb for the past two years. The pain had worsened in the past two weeks. The patient was positive for Hildreth’s, Love’s pin, and cold sensitivity tests. The previous x-ray showed no abnormalities in the left thumb. MRI found a hyperdense subungual lesion in the dorsal interphalangeal joint of the left thumb. We then performed an excision using the transungual approach. Histopathological findings found a relatively well-circumscribed lesion of the glomus apparatus absent of abnormal mitosis and necrosis. Two months after the excision, the patient reported no symptoms of recurrency, nail deformity, or other adverse outcomes. Conclusion: Patients typically present a chief complaint of chronic paroxysmal throbbing nail pain that persists for years, increases following exposure to cold environments, and is disproportionately exacerbated with the slightest touch. Hildreth’s, Love’s Pin, and cold sensitivity tests are special examinations that elicit or suppress pain. As with most benign tumors, complete excision usually yields good results. Adequate knowledge about diagnostic methods will help patients achieve early intervention and cure.

A Rare Endobronchial Tumor in a Pediatric Patient.

A pediatric patient who presented with non-specific respiratory symptoms, including mild hemoptysis, wheezing, and eventual respiratory distress, was found to have a rare endobronchial inflammatory myofibroblastic tumor obstructing her right mainstem bronchus. It was diagnosed and initially debulked using bronchoscopy, which helped to stabilize the patient and eliminate the need for supplemental oxygen. The patient subsequently underwent successful removal of the residual tumor with parenchymal-sparing sleeve resection. This case highlights the importance of pursuing appropriate imaging along with diagnostic and therapeutic bronchoscopy for an endobronchial lesion to help manage pediatric patients with persistent respiratory symptoms.

Endoscopic Ultrasound-Guided Drainage of Pelvic Fluid Collections with Lumen-Apposing Metal Stents

Introduction: A pelvic abscess is a potential life-threatening condition that should be managed conservatively whenever possible. Currently, computed tomography or ultrasound-guided percutaneous drainage is still the gold standard approach for pelvic fluid collections (PFCs) requiring intervention. More recently, endoscopic ultrasound (EUS) drainage using lumen-apposing metal stents (LAMSs) has been used off-label in PFCs with similar efficacy, a favorable safety profile, better quality of life, and generally a shorter duration of treatment when compared to the gold standard treatment. Methods: An observational retrospective analysis of 6 patients who underwent EUS-guided PFC drainage with LAMS at our institution was conducted. Records were reviewed to identify etiology, size of the collection, number of endoscopic procedures required until complete resolution, stent indwelling time, concomitant surgical or percutaneous associated procedures, successful removal and resolution. Results: The 6 patients included had an average age of 69 years old and 5 (83.3%) were male. The average size of the PFCs was 72.5 mm. All patients (100%) had successful drainage following LAMS placement, though 1 patient had an early recurrence. The mean stent indwelling time in our study was 6.7 days. An additional percutaneous or surgical drainage intervention was not required in any of the participants. Also, no adverse events related to the procedure were reported during the follow-up period. Conclusion: EUS-guided drainage of PFCs with LAMS is a safe and minimally invasive technique, which allows rapid PFC resolution, with no need for percutaneous or surgical drainage interventions.

Balancing risks and outcomes in schwannoma treatment: Case series

Schwannomas are rare benign tumors originating from Schwann cells of peripheral nerve sheaths, occasionally presenting intraosseously in the oral and maxillofacial region. Management decisions for these tumors require careful consideration of their location, size, and impact on surrounding structures. We present two contrasting cases of schwannomas: One involving a non-surgical approach due to extensive involvement and proximity to critical structures and the other necessitating surgical excision for a well-defined intraosseous lesion. The first case, in a 28-year-old female, highlighted the decision to monitor the lesion due to its significant size and location, while the second case, in a 20-year-old female, demonstrated successful surgical removal with histopathological confirmation of a benign schwannoma. These cases underscore the importance of tailored management strategies based on thorough clinical, radiographic, and histopathological assessments to optimize outcomes and minimize risks associated with surgical intervention.

Outcomes of tunnelled cuffed centrally inserted central catheter removal: A retrospective cohort study.

Most children with cancer will require a central venous access device (CVAD) to administer cancer treatment. A commonly used CVAD is a tunnelled cuffed centrally inserted central catheter (TC-CICC). There is little information available to guide best practice when removing this type of CVAD. At our institution, TC-CICCs are removed by using either the traction or dissection methods. This study will describe the outcomes associated with each technique. A retrospective cohort study was undertaken at a quaternary children's hospital in Melbourne, Australia. Data related to characteristics of TC-CICC removal success, post-removal complications and an economic evaluation were carried out. There were 149 patients who underwent traction removal and 100 who had their TC-CICC removed using the dissection technique. In the traction group, 136/149 (91%) patients had their device successfully removed on the first attempt, whereas 99/100 (99%) were removed on the first attempt with dissection. Of the 136 successful traction removals, cuff status was documented in 72 cases. The cuff remained in situ in 46/72 (64%) cases, and six of 72 (8%) patients experienced a complication. There were no documented cases of cuff retention in the dissection group. In the 2019-2020 financial year, the estimated average cost of traction removal was A$387, whereas the estimated average cost of day case surgery was A$2560. This study has highlighted that the traction technique is a safe, efficient and cost-effective approach to TC-CICC removal. Further research is required to understand the patient and family experience of TC-CICC removal.

Double J Ureteral stent removal in children non cystoscopically: A preferred innovation.

Objective: To determine the feasibility of non cystoscopic removal of double J ureteral (DJ) stent using a foley catheter with suture in children in terms of success rate, number of attempts required and complications. Study Design: Cross Sectional study. Setting: Department of Pediatric Surgery, Services Hospital, Lahore. Period: August 2022 to August 2023. Methods: All the children who underwent DJ stent placement for any urological procedure were included if DJ stent was seen in the bladder postoperatively. After informed consent, under sedation and aseptic measures, the foley catheter with suture already passed through its eye, was introduced per urethral after adequate lubrication. The foley was given five to six rotations in clockwise direction for right sided and anti-clockwise for left sided stents respectively and pulled out keeping traction on the suture. In case of three failed attempts, a cystoscope was introduced under general anesthesia and the stent was removed. Successful removal, number of attempts needed, time taken, and post removal complications were noted to determine feasibility of the procedure. Results: Out of twenty patients, 17 patients (85%) underwent successful removal of DJ stent. The failure rate was 15% as three patients required cystoscope assisted removal. In 13 patients (76.5%) DJ stent was removed in first attempt, whereas in 4(23.5%) patients it required two attempts. Mean time taken was 8.83±7.33 minutes. Complications were noted in 2 patients (10%). Conclusion: Removal of DJ stent in children without cystoscope, using a foley catheter with suture is a safe and feasible procedure with a high success rate and should be attempted in selected cases.

6645 Paraganglioma or Benign Ectopic Thyroid Tissue?

Abstract Disclosure: J.A. Dower: None. R. MacLeod: None. B. Cardoso: None. C. Matouk: None. S. Mehra: None. G. Riccio: None. L. Williams: None. S.K. Majumdar: None. Introduction: During gestation, cells destined to form the thyroid descend through the thyroglossal duct; ectopic thyroid tissue may deposit anywhere along this route from tongue base to mediastinum (1). Less commonly, thyroid tissue can be found lateral to the duct, either alone or in association with a lymph node (2). We present a case of lateral ectopic thyroid tissue mimicking paraganglioma. Clinical Case: A healthy 32-year-old woman presented to ENT with cervical adenopathy persisting for several months after a flulike illness. FNA showed no evidence of malignancy. A neck CT with contrast ordered for further evaluation revealed a 3.2 x 2.3 x 1.5 cm enhancing mass within the right carotid space, splaying the external and internal carotid artery branches, most concerning for paraganglioma. A second, smaller lesion was noted inferiorly. Neck MRI confirmed these findings and revealed a subcentimeter T2 lesion within the right thyroid lobe. The patient was referred to endocrine for further workup. She had no symptoms of sympathetic hyperactivity and no family history suggestive of pheochromocytoma or paraganglioma. Biochemical workup was largely within normal limits: plasma metanephrines 53 pg/mL (57), normetanephrines 94 pg/mL (148), calcitonin <2 pg/mL, TSH 1.210 uIU/mL (0.27-4.2), FT4 1.52 ng/dL (0.8-1.7). Follow-up 24-h urine studies were also unremarkable: metanephrines 166 mcg (36-190), normetanephrines 159 mcg (35-482). Brain MRI, chest CT, and abdomen/pelvis MRI were negative for additional masses. DOTATATE PET/CT was completed to determine if the thyroid lesion was another potential paraganglioma requiring resection versus a nodule amenable to biopsy; uptake was confined to the carotid space lesions, so FNA of the thyroid nodule was considered safe. Thyroid FNA revealed FLUS with genetic testing indicating low likelihood of malignancy. The patient underwent tumor embolization followed by neck dissection with successful removal of both the larger and smaller masses identified on imaging. Frozen and permanent tissue section revealed that both masses consisted of benign thyroid tissue without associated lymphoid tissue. The patient experienced jaw pain with eating after surgery and is under consideration for Botox injection. Conclusion: Benign thyroid tissue can deposit in unexpected places, mimicking malignancy and paraganglioma, alike. Even a very thorough workup can mistake the identity of a mysterious mass; only the tissue itself can make the diagnosis.

8673 Exploring A Case Study On Navigating Complexities In Endocrine Health And Reproductive Challenges

Abstract Disclosure: S.Y. Rizvi: None. E. Villanueva: None. Introduction: Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting many reproductive-age women, characterized by irregular menstrual cycles, hirsutism, and challenges with fertility. In this case study, we delve into the medical history of a 24-year-old female presenting with PCOS-related symptoms, hirsutism, and infertility, unraveling the multifaceted aspects of her healthcare journey. Case Description: This patient's diagnostic path began when she received an initial diagnosis of PCOS in her home country due to irregular menstrual periods and clinical signs of hirsutism. Her treatment included metformin, but it was interrupted when she relocated to the United States. Upon her arrival in the U.S., her medical course took an unexpected turn as further evaluations revealed elevated salivary cortisol (++), and a 24-hour urine free cortisol recorded 94.2 mcg (normal 4-50 mcg), indicating hypercortisolism. DHEAS: 730 mcg/dl (normal 18-390 mcg/dl), 17-hydroxyprogesterone: 508 (pre-midluteal: 431), free testosterone: 13 pg/ml (normal 0.1-6.4 pg/ml), with normal CBC, TSH, prolactin, and TPO. CT scan showed large 4.8 cm left adrenal mass. These findings indicated adrenal Cushing's syndrome, leading to referral to a tertiary care hospital's endocrine surgeon. Two months post-adrenalectomy, successful removal of the adrenal mass left the patient with relative adrenal insufficiency. Hydrocortisone replacement therapy was initiated, addressing Cushing's syndrome and revealing a potential factor contributing to infertility. Postoperatively, the patient entered the first trimester unexpectedly, complicating her case. Ensuring proper hydrocortisone levels became crucial for her well-being and the fetus, prompting a collaborative approach with obstetricians and maternal-fetal medicine specialists for optimal pregnancy care. Despite ongoing PCOS effects, including hirsutism, treatment options were limited by pregnancy constraints, deferring Aldactone due to its contraindication during pregnancy. Continuous monitoring included hormonal assessments, metabolic panels, and thyroid tests, aiming to balance adrenal insufficiency, PCOS symptoms, and a healthy pregnancy. Conclusion: This case emphasizes challenges in differentiating PCOS from adrenal Cushing's due to overlapping symptoms. Despite classic symptoms, the initial PCOS misdiagnosis highlights the need for vigilance and comprehensive diagnostics. Complex cases underscore the importance of individualized management and interdisciplinary collaboration. Positive outcomes in complex endocrine disorders and pregnancy are attainable through accurate diagnoses and tailored treatments. The case underscores the critical importance of meticulous evaluation for successful outcomes in challenging medical scenarios. Presentation: 6/3/2024

The effect of enzymatic GAG degradation on transverse shear properties of porcine cornea

The structural integrity of cornea depends on properties of its extracellular matrix, mainly a mixture of collagen fibers and soluble proteoglycans (PGs). PGs are macromolecules of negatively charged sulphated glycosaminoglycans (GAGs) covalently attached to a protein core. GAGs appear as bridges between adjacent collagen fibers and could facilitate force transfer between them. Furthermore, GAGs are responsible for corneal hydration by attracting and maintaining water molecules into the extracellular matrix. Based on these observations, GAGs are expected to be essential for biomechanical properties of cornea. The primary objective of the present study was to determine the effects of GAGs on shear properties of cornea. For this purpose, GAGs were enzymatically removed from porcine corneal disks by keratanase II enzyme. After confirming the successful removal of GAGs by histochemical methods, torsional rheometry was performed to characterize the shear stiffness of GAG-depleted samples as a function of axial strain. It was found that the shear modulus of all samples was a function of applied shear strain and compressive strain. Beyond the range of linear viscoelastic response, the average complex shear modulus decreased with increasing the shear strain. Increasing the axial strain from 0% to 40% significantly increased the average complex shear modulus of corneal disks in all groups. Finally, the enzyme treatment with keratanase II enzyme significantly decreased the shear stiffness. The experimental measurements were discussed in terms of microstructural and compositional properties of corneal extracellular matrix and it was concluded that GAGs play a significant role in defining shear properties of cornea.

Successful occluder removal and reocclusion of an atrial septal defect after occluder immigration to aortic arch: a case report

BackgroundAtrial septal defect (ASD) is a common congenital heart disease, and currently, transcatheter intervention is the most common clinical treatment method. However, certain complications still occur during the percutaneous process, among which occluder loss and displacement are rare but serious complication. Although the probability of occluder loss and displacement is low, severe cases can endanger life.Case presentationHere, we report the case of a patient who underwent ASD closure in which the occluder fell off into the aortic arch, the detached occluder was recovered through catheter intervention, and the patient underwent ASD closure again.ConclusionsIn this case report, we highlight that although percutaneous closure of an ASD is regarded as a routine procedure, clinicians should remember the possibility of complications, especially occluder loss and displacement. Therefore, interventionist should carefully evaluate the situation before intervention closure, establish standardized interventional treatment procedures, and provide timely treatment follow-up.

Compound odontoma and impaction of the lower left deciduous canine in a 4-year-old child: diagnosis and treatment.

Odontomas are the most common odontogenic tumours, often considered hamartomas rather than true neoplasms. These mixed tumours consist of fully differentiated dental tissues, including enamel, dentin, cementum, and pulp. Odontomas can be classified into compound and complex types. While typically asymptomatic, they are often discovered during routine radiographic examinations for delayed tooth eruption. The management of odontomas generally involves surgical removal, which is effective in resolving associated dental impactions. We present the case of a healthy 4-year-old child who presented with the absence of the lower left deciduous canine (tooth 7.3) in the dental arch. Radiographic examination revealed multiple radiopaque masses indicative of a compound odontoma associated with the unerupted deciduous canine. Following detailed imaging and surgical planning, the odontoma was successfully enucleated under conscious sedation with nitrous oxide. The surgical procedure was performed without extracting the retained canine. Post-operative follow-up at two weeks showed excellent healing, and at seven months, partial eruption of the canine was observed, confirming the odontoma's role in impeding its eruption. This case underscores the importance of early diagnosis and management of odontomas to prevent potential impaction of associated teeth. The successful surgical removal of the odontoma facilitated the spontaneous eruption of the lower left deciduous canine, highlighting the effectiveness of early intervention. Conscious sedation with nitrous oxide proved to be a valuable tool in managing the young patient, ensuring cooperation and comfort during the procedure. Early identification and treatment of odontomas are crucial for promoting normal dental development and preventing future malocclusions.

Transoral approach for hilo-parenchymal submandibular stones: outcomes and predictors of success

ObjectiveTo evaluate the efficacy and safety of transoral surgical management for complex submandibular gland (SMG) stones. Study DesignA retrospective cohort study of 240 patients treated for sialolithiasis between 2015 and 2018, focusing on 57 cases of submandibular gland stones that underwent stone removal procedures. Treatment methods, success rates, and complications were analyzed using Kaplan-Meier analysis, Cox proportional hazards regression, and multiple logistic regression. ResultsTransoral surgical release was successful in 72.9% of cases. The overall complication rate was 10%. Stone size (HR = 0.85, p = 0.004) and hilar location (HR = 0.72, p = 0.036) were associated with longer symptom resolution time. Multivariate analysis revealed that stone size (OR = 0.78, p = 0.009) and hilar location (OR = 0.45, p = 0.029) decreased the odds of successful removal. ConclusionTransoral surgical management of hilo-parenchymal SMG stones appears to be a safe and effective approach, potentially reducing the need for sialoadenectomy.
