Can chatbots enhance the management of pediatric sialadenitis in clinical practice?

OBJECTIVE: The purpose of this study was to assess how well ChatGPT, an AI-powered chatbot, performed in helping to manage pediatric sialadenitis and identify when sialendoscopy was necessary. METHODS: 49 clinical cases of pediatric sialadenitis were retrospectively reviewed. ChatGPT was given patient data, and it offered differential diagnoses, proposed further tests, and suggested treatments. The decisions made by the treating otolaryngologists were contrasted with the answers provided by ChatGPT. Analysis was done on ChatGPT response consistency and interrater reliability. RESULTS: ChatGPT showed 78.57% accuracy in primary diagnosis, and 17.35% of cases were considered likely. On the other hand, otolaryngologists recommended fewer further examinations than ChatGPT (111 vs. 60, p < 0.001). For additional exams, poor agreement was found between ChatGPT and otolaryngologists. Only 28.57% of cases received a pertinent and essential treatment plan via ChatGPT, indicating that the platform's treatment recommendations were frequently lacking. For treatment ratings, judges' interrater reliability was greatest (Kendall's tau = 0.824, p < 0.001). For the most part, ChatGPT's response constancy was high. CONCLUSIONS: Although ChatGPT has the potential to correctly diagnose pediatric sialadenitis, there are a number of noteworthy limitations with regard to its ability to suggest further testing and treatment regimens. Before widespread clinical use, more research and confirmation are required. To guarantee that chatbots are utilized properly and effectively to supplement human expertise rather than to replace it, a critical viewpoint is required.

MR sialographic assessment of the masseter muscle and the ductal kinking in patients with recurrent parotitis.

Dysfunction of the masseter muscle may cause pathological kinking of the parotid duct leading to parotitis; MR sialography is a non-invasive radiological examination that allows to evaluate dynamically the ductal system of the parotid glands. In the present study we aimed to assess the relationships between Stensen's duct and masseter muscle and their implications in the aetiopathogenesis of recurrent parotitis secondary to masseter muscle dysfunction. Forty-one patients with recurrent unilateral parotitis and nine with bilateral recurrent parotitis, all with a clinical suspicious of masseter muscle hypertrophy due to bruxism were enrolled. They underwent ultrasonography as a first line examination and then MR sialography and sialendoscopy. Different anatomical features were studied. Involved parotid glands had a wider duct compared to contralateral unaffected parotid glands of patients with recurrent parotitis (p = 0.00134); male subjects with parotitis had a longer duct compared to the salivary glands of healthy patients (p = 0.00943 for affected glands and p = 0.00629 for the contralateral). A concordance between the evidence of an acute duct angle during sialendoscopy and a wider duct in patients with parotitis was observed although not statistically significant. These initial findings suggest that the masticatory muscle dysfunction related to bruxism seems to condition alteration of parotid duct course and anatomy thus favouring the occurrence of recurrent parotitis. A specific diagnostic iter based on clinical evaluation, dynamic ultrasonography and MR sialography, is therefore, mandatory to confirm the relationship between masseter muscle anatomy and parotid duct anomalies; this is the premise for an adequate therapeutic approach to underlying masticatory muscle disorder.

Sirolimus treatment for paediatric head and neck lymphatic malformations: a systematic review.

PURPOSE: This PRISMA-compliant systematic review aimed to assess risks and benefits of sirolimus treatment for paediatric lymphatic malformations by focusing not only on treatment efficacy but also on possible treatment-related adverse events, and treatment combinations with other techniques. METHODS: Search criteria were applied to MEDLINE, Embase, Web of Science, Scopus, Cochrane Library, and ClinicalTrials.gov databases and included all studies published up to March 2022 reporting paediatric lymphatic malformations treated with sirolimus. We selected all original studies that included treatment outcomes. After the removal of duplicates, selection of abstracts and full-text articles, and quality assessment, we reviewed eligible articles for patient demographics, lymphatic malformation type, size or stage, site, clinical response rates, sirolimus administration route and dose, related adverse events, follow-up time, and concurrent treatments. RESULTS: Among 153 unique citations, 19 studies were considered eligible, with reported treatment data for 97 paediatric patients. Most studies (n = 9) were case reports. Clinical response was described for 89 patients, in whom 94 mild-to-moderate adverse events were reported. The most frequently administered treatment regimen was oral sirolimus 0.8 mg/m2 twice a day, with the aim of achieving a blood concentration of 10-15 ng/mL. CONCLUSION: Despite promising results for sirolimus treatment in lymphatic malformation, the efficacy and safety profile of remains unclear due to the lack of high-quality studies. Systematic reporting of known side effects, especially in younger children, should assist clinicians in minimising treatment-associated risks. At the same time, we advocate for prospective multicentre studies with minimum reporting standards to facilitate improved candidate selection.

Feasibility of 3D printed salivary duct models for sialendoscopic skills training: preliminary report.

PURPOSES: To explore the feasibility of 3D printed salivary duct models for the sialendoscopic skills training. METHODS: Healthy volunteers and patients affected by obstructive salivary gland disorders were submitted to 3 Tesla MR sialography. The MR data underwent an image segmentation process to produce the 3D printed salivary duct prototypes. Sialendoscopies were carried out by three groups of investigators with different levels of endoscopic experience. Realism, usefulness of the training process and potential advantages of the 3D printed models in the preoperative surgical planning were evaluated by means of a specific survey. RESULTS: Four cases were included in our study: one healthy parotid, one submandibular gland, one case of lithiasis and one of stenosis involving the parotid gland. In all cases, the three groups of investigators successfully explored the salivary ducts up to the tertiary branches, detected the cause of obstruction and correctly treated it. Seven untoward events occurred during the operative sialendoscopies. Overall, the questionnaire score was about 79.3%, reflecting a positive impression regarding the models on behalf of all the investigators. CONCLUSIONS: 3D printed salivary duct models resulted feasible for the sialendoscopic skills training. The opportunity to reproduce the patient-specific anatomy may add further information useful in the preoperative decision making. These positive results should be verified by further researches and experiences.

A retrospective evaluation of the etiology of unilateral vocal fold paralysis over the last 25 years.

Previous studies have shown that the etiology of laryngeal paralysis has changed over the last decades, with an increase in the incidence of cases attributable to thyroid surgery. The aim of this study was to evaluate longitudinal changes in the etiology of unilateral vocal fold paralysis (UVFP) in a single institution over the last 25 years. This retrospective study analyzed the etiology of UVFP between 1990 and 2015 by comparing a cohort of patients treated in 1990-1992 with a cohort treated in 2013-2015. The final analysis was based on data concerning 356 patients (38.8 % males; mean age 55.3 ± 20.4 years): 113 in the 1990-1992 cohort, and 243 in the 2013-2015 cohort. The main cause of UVFP in the population as a whole was thyroidectomy (41.3 %), followed by an idiopathic origin (25.3 %) and thoracic surgery (12.1 %); this was confirmed in both intra-group analyses. There was a statistically significant association between etiology and the sub-group periods: the prevalence of post-thyroidectomy UVFP was highly significantly lower in the 2013-2015 cohort (35.4 vs 54.0 %), and the prevalence of idiopathic cases was higher (28.4 vs 18.6 %). Etiology significantly related to gender in both cohorts (p value ≤0.001). In the 2013-2015 cohort, there was also a statistically significant relationship between etiology and age classes (p value 0.017), and the left side was more frequently affected than the right (67.1 vs 32.9 %). Our findings document changes in the etiological pattern of UVFP over the last 25 years, with a considerable decrease in post-thyroidectomy UVFP, and a growing predominance of idiopathic and post-thoracic surgery UVFP.

3D-4K Exoscope-Assisted CO2 Laser Supraglottoplasty for Severe Laryngomalacia in a Pediatric Patient.

Laryngomalacia is the most frequent congenital laryngeal anomaly. Surgery is possible by means of cold knife, carbon dioxide (CO2 ) laser, microdebrider and coblation, traditionally under microscopic view. We here describe the use of the 3D-4K exoscope assisted CO2 laser supraglottoplasty in tubeless general anesthesia in spontaneous breathing in a 5 month-old patient with severe laryngomalacia. Laryngoscope, 134:1359-1362, 2024.

Topographic distribution of biofilm-producing bacteria in adenoid subsites of children with chronic or recurrent middle ear infections.

OBJECTIVES: Bacterial biofilms have been found in the adenoids of children with recurrent acute otitis media (AOM) and persistent otitis media with effusion (OME). However, the possible difference in biofilm-producing bacteria (BPBs) between the adenoid surface at the nasopharyngeal dome (ND) and near the ostium of the eustachian tube (ET) has not been investigated. This study aimed to assess the difference in BPBs between adenoid biopsy specimens of the ND and those taken near the pharyngeal ostium of the ET in children with chronic adenoiditis with recurrent AOM and/or persistent OME. METHODS: We collected adenoid biopsy specimens from the ND and ET during transoral endoscopic adenoidectomy to assess BPB by means of spectrophotometric analysis. RESULTS: We collected 135 adenoid biopsy specimens from 45 children. BPBs were detected significantly (p = 0.04) more frequently in the ET samples than in the ND samples, mainly Staphylococcus aureus. Although the prevalence of S aureus was slightly greater in the ND samples, and that of Streptococcus pneumoniae and Moraxella catarrhalis was slightly greater in the ET samples, these differences were not statistically significant. CONCLUSIONS: The fact that BPBs were significantly more frequently located near the ostium of the ET suggests that the adenoids are a reservoir for bacteria and indicates that hypertrophic adenoids (particularly hypertrophy near the ostium of the ET) play a role in recurrent AOM and/or OME.

Narrow-band imaging in the diagnosis of vascular nasal lesions.

The management of unilateral nasal lesions can sometimes be a challenge and an ordinary bioptic assessment should be avoided in order to prevent complications due to their possible vascular or meningoencephalic origin. Narrow-band imaging (NBI) endoscopy could improve the diagnosis of vascular nasal formations by enhancing the visualisation of the mucosal microvascular supply. We describe the case of a 68-year-old male patient who was brought to our attention because of a left nasopharyngeal mass that had elsewhere been unsuccessfully biopsied (with conspicuous bleeding) and assessed by means of traditional endoscopic and radiological techniques. NBI endoscopy revealed increased vasculature covering most of the mucosal surface without any features suggestive for malignancy. Subsequent angiography showed that the feeding vessel was the left sphenopalatine artery, which was embolised using 150-250 µm Contour embospheres. The mass was then completely removed surgically using an NBI-assisted endoscopic technique, and a histopathological examination revealed it was a hemangiopericytoma-like (HPCL) tumor. This case suggests the usefulness of NBI endoscopy in diagnosing unilateral vascularised nasal lesions and guiding the therapeutic approach before and during major surgery.

Image-guided and sialendoscopy-assisted transoral approach for parotid duct stenosis and megaduct.

OBJECTIVE: The aim of this communication was to introduce a novel combined image (magnetic resonance and computed tomography-guided and sialendoscopy-assisted transoral approach for the treatment of a parotid duct stenosis with megaduct. METHODS: A 46-year-old woman was referred to our department for recurrent infections of the right parotid gland following unsuccessful multiple transoral surgical approaches for a Stensen's duct stricture with megaduct. An image (magnetic resonance and computed tomography)-guided and sialendoscopy-assisted transoral sialodochoplasty was planned and performed. RESULTS: No complications occurred. The patient was discharged 2 days after surgery. No more swelling or infections occurred. The patient is currently symptom-free after a follow up of 11 months. CONCLUSION: Although imaging navigation means more technical effort and costs, this novel approach can be considered a viable surgical opportunity for distal and mid-third parotid duct stenosis with concomitant megaduct, particularly in cases of persistent inflammation or iatrogenic scars due to previous surgery.

An Unusual Retained Choanal Foreign Body: A Possible Complication of COVID-19 Testing With Nasopharyngeal Swab.

Testing for coronavirus disease 2019 is critical in controlling the pandemic all over the world. Diagnosis of severe acute respiratory syndrome coronavirus-2 infection is based on real-time polymerase chain reaction performed on nasopharyngeal swab. If not adequately performed, the viral specimen collection can be painful and lead to complications. We present a complication occurred during a nasopharyngeal swab collection performed in a noncooperative patient where the plastic shaft of the swab fractured during the procedure, resulting in swab tip retention deep into the nasal cavity. The foreign body was found endoscopically, stuck between the nasal septum and the superior turbinate tail at the upper level of the left choana and removed under general anesthesia in a negative pressure operating room with the health care personnel wearing personal protective equipment. Unpleasant complications like the one described can happen when the swab is collected without the necessary knowledge of nasal anatomy or conducted inappropriately, especially in noncooperative patients. Moreover, the design of currently used viral swabs may expose to accidental rupture, with risk of foreign body retention in the nasal cavities. In such cases, diagnosis and treatment are endoscopy-guided procedures performed in an adequate setting to minimize the risk of spreading of the pandemic.

Bilateral Sensorineural Hearing Loss Related to a Skull Base Spontaneous Cerebrospinal Fluid Leak: A Case Report and Literature Review.

Spontaneous intracranial hypotension (SIH) is a rare condition characterized by orthostatic headache, pulsatile tinnitus, vertigo, nausea, and fluctuating hearing loss; this latter seems to be due to the development of cochlear endolymphatic hydrops following negative cerebrospinal fluid (CSF) pressure transmitted to the perilymphatic space through a patent cochlear aqueduct. We here describe a case of bilateral progressive sensorineural hearing loss (SNHL) due to intracranial hypotension caused by an undiagnosed spontaneous CSF leak from a skull base defect in a middle-aged woman. To the best of our knowledge, this is the first report describing a SNHL in a patient affected by SIH secondary to sphenoidal CSF leak.

Endoscopic surgery under tubeless anesthesia and spontaneous breathing for a congenital laryngeal web in an infant: A case report.

Congenital laryngeal webs are rare and are defined as thick epithelium-covered fibrous tissue lying between the vocal folds; the anterior glottis is the most common site of involvement, with possible extension to the subglottic region. The association with chromosome 22q11.2 deletion syndrome has also been reported. Symptoms have been abnormal or absent crying and airway obstruction since birth. Management strategies range from endoscopic division using cold instruments to open surgery for severe webbing. In endoscopic surgery, the need for tubeless anesthesia and spontaneous breathing is fundamental for obtaining the best surgical outcome. Here, we describe the case of a 4-month-old female patient affected by a type II glottic web according to Cohen, who was treated by simple endoscopic division in spontaneous breathing.

A misdiagnosed laryngeal foreign body causing recurrent wheezing in a pediatric patient: Case report.

Key clinical message: The recurrence of respiratory symptoms without a clear clinical reason in children can be secondary to the presence of an unknown foreign body of the airways. In such cases, endoscopy of the airways is always necessary, regardless of the patient's age. Abstract: The management of foreign bodies of the pediatric airway can be challenging. The clinical presentation may vary and, in case of recurrent respiratory symptoms without a clear clinical cause, the presence of a foreign body of the airway should be suspected. We describe the case of a 13-month-old patient, weight 11 kg, with a misdiagnosed subglottic foreign body causing dysphonia and worsening respiratory distress, removed by means of a direct laryngotracheoscopy in tubeless general anesthesia in spontaneous breathing.

Impact of the COVID-19 pandemic on paediatric otolaryngology: a nationwide study.

Objective: The COVID-19 pandemic profoundly modified the work routine in healthcare; however, its impact on the field of paediatric otorhinolaryngology (ORL) has been rarely investigated. The aim of this study was to assess the impact of COVID-19 on paediatric ORL. Methods: A questionnaire was developed by the Young Otolaryngologists of the Italian Society of ORL-Head and Neck Surgery (GOS). The questionnaire consisted of 26 questions related to workplace and personal paediatric ORL activities. The link was advertised on the official social media platforms and sent by e-mail to 469 Italian otolaryngologists. Results: The questionnaire was completed by 118 responders. During the pandemic, the main reduction was observed for surgical activity (78.8%), followed by outpatient service (16.9%). The conditions that were mostly impacted by a delayed diagnosis were respiratory infections in 45.8% of cases and sensorineural hearing loss in 37.3% of cases. Conclusions: Paediatric ORL was highly impacted by the COVID-19 pandemic, with a significant reduction of surgical and outpatient activities and a delay in time-sensitive diagnosis. Therefore, the implementation of new strategies, such as telemedicine, is recommended.

High-Definition 3D Exoscope in Pediatric Otorhinolaryngology: A Systematic Literature Review.

This PRISMA-compliant systematic review aimed to investigate the use of and the most common procedures performed with the novel 3D 4K exoscope in surgical pediatric head and neck settings. METHODS: Search criteria were applied to PubMed, EMBASE and the Cochrane Review databases and included all studies published up to January 2023 reporting 3D 4K exoscope-assisted surgeries in pediatric patients. After the removal of duplicates, selection of abstracts and full-text articles, and quality assessment, we reviewed eligible articles for number of patients treated, age, surgical procedures, and outcomes. RESULTS: Among 54 potentially relevant records, 5 studies were considered eligible and included in this systematic review, with reported treatment data for 182 patients. The surgical procedures belong to the otologic field (121 cases), head and neck surgery (25 cases) and transoral surgery (36 cases). Exoscopy allowed high quality visualization of anatomical structures during cochlear implantation and during reconstruction in head and neck surgery; moreover, it improved the surgical view of surgeons, spectators and ENT students. CONCLUSIONS: The use of 3D 4K exoscopy has shown promising potential as a valuable tool in pediatric ORL-head and neck surgery; nevertheless, further validation of these encouraging outcomes is necessary through larger-scale studies specifically focused on pediatric patients.

Minimally invasive transoral robotic surgery for hiloparenchymal submandibular stone: Technical note on Flex Robotic System.

Flex Robotic System allows a minimally invasive approach for transoral removal of submandibular salivary stones.

Unilateral silent sinus syndrome: A case report.

Silent sinus syndrome (SSS) is a rare clinical condition, commonly unilateral, secondary to the obstruction of the osteomeatal complex, subsequent negative pressure in the maxillary sinus, and collapse of the orbit floor and sinus walls. We describe a case of unilateral SSS treated by means of functional endoscopic sinus surgery.

COVID-19 isolation drape for sialendoscopy-assisted transfacial approach to parotid gland.

Surgical procedures requiring close contact with saliva, such as salivary gland surgery, may determine the risk of spreading the SARS-CoV-2 infection. The use of PPE and isolation settings are mandatory to protect health workers.

Surgical treatment of a congenital dacryocystocele by means of microdebrider marsupialization in a newborn.

Congenital dacryocystocele is a rare clinical condition, more commonly unilateral, secondary to the defective canalization of the nasolacrimal duct. In case of failure of conservative treatment, surgical marsupialization is recommended. We describe the case of a 40-day-old male newborn treated by means of microdebrider marsupialization.

Deep Sedation for Pediatric Parotid Sialendoscopy in Juvenile Recurrent Parotitis.

Sialendoscopy is a minimally invasive diagnostic and therapeutic tool for juvenile recurrent parotitis (JRP); the procedure is under general anesthesia, but local anesthesia has been used for sialendoscopy in children >8 years. Based on the experience in children with sedation for gastrointestinal endoscopy, we investigated the reliability and safety of deep sedation for sialendoscopy in JRP. Six children (3 females, 6-13 years) with episodes of parotid swelling underwent interventional (duct dilation and steroid irrigation) sialendoscopy with intravenous bolus of 1 mg/kg propofol and 1 mcg/kg fentanyl, and continuous infusion of 2 mg/kg/h propofol. Sialendoscopy under deep sedation was successfully performed in all the patients; the procedure was well tolerated, without any adverse effects. One event of full awakening was registered and promptly solved without needing to interrupt the procedure. Effectiveness of sialendoscopy under deep sedation was subjectively attested by high positive scores obtained at post-operative standardized questionnaires administered to the patients and their parents, and objectively by the lack of clinical recurrences during the follow-up. The combination of propofol and fentanyl seems to be a reliable and safe means of sedating children with JRP undergoing sialendoscopy.
