Exploring the potential of Chat-GPT as a supportive tool for sialendoscopy clinical decision making and patient information support.

INTRODUCTION: Sialendoscopy has emerged in the last decades as a groundbreaking technique, offering a minimally invasive approach for exploring and managing salivary gland disorders. More recently, the advent of chatbots, powered by advanced natural processing language and artificial intelligence algorithms, has revolutionized the way healthcare professionals and patients access and analyze medical information and potentially will support soon the clinical decision-making process. MATERIALS AND METHODS: A prospective, cross-sectional study was designed to assess the level of agreement between Chat-GPT and 10 expert sialendoscopists aiming the capabilities of Chat-GPT to further improve the management of salivary gland disorders. RESULTS: The mean level of agreement was 3.4 (SD: 0.69; Min: 2, Max: 4) for Chat-GPT's answers while it was 4.1 (SD: 0.56; Min: 3, Max: 5) for the group of EESS (p < 0.015). The overall Wilcoxon signed-rank test yielded a significance level of p < 0.026 when comparing the level of agreement between Chat-GPT and EESS. The mean number of therapeutic alternatives suggested by Chat-GPT was 3.33 (SD: 1.2; Min: 2, Max: 5), while it was 2.6 (SD: 0.51; Min: 2, Max: 3) for the group of EESS; p = 0.286 (95% CI - 0.385 to 1.320). CONCLUSION: Chat-GPT represents a promising tool in the clinical decision-making process within the salivary gland clinic, particularly for patients who are candidates for sialendoscopy treatment. Additionally, it serves as a valuable source of information for patients. However, further development is necessary to enhance the reliability of these tools and ensure their safety and optimal use in the clinical setting.

Prophylactic antibiotics in sialendoscopy: a randomized clinical trial.

OBJECTIVE: Antibiotics have been prescribed routinely in sialendoscopy procedures to reduce the risk of postoperative infection, despite the limited evidence supporting this practice. Being necessary to assess the need for antibiotics in Sialendoscopy, aiming to provide evidence-based guidance to clinicians regarding antibiotic administration in this procedure. MATERIALS & METHOD: A prospective, randomized, double-blind, controlled clinical trial to evaluate the of prophylactic antibiotics in Sialendoscopy was designed. RESULTS: A total of 80 patients were included in this study, including 57 females (71.8%) and 23 males (28.8%). In terms of prophylaxis, 36 patients (45%) received prophylactic treatment, and 44 patients (55%) did not. The occurrence of infectious events was observed in 2 patients (5.6%) with prophylaxis and 4 patients (9.1%) without prophylaxis. However, this difference was not statistically significant (p = 0.556). CONCLUSION: In conclusion, our prospective, randomized clinical trial aimed to address the debate regarding the use of prophylactic antibiotics in sialendoscopy. Our study's findings suggest that the routine use antibiotics may not be necessary to prevent postoperative infections in sialendoscopy procedures. These results have important implications for clinical practice, potentially reducing the unnecessary use of antibiotics and addressing concerns related to antibiotic resistance and adverse drug reactions.

Sialendoscopy-assisted transoral approach for parotid gland lithiasis.

INTRODUCTION: Although lithiasis represents more than 60% of all cases of salivary gland obstruction, only 20% occurs in the Stensen´s duct. Nonetheless, the potential complications related to parotid gland surgery due to facial nerve injury, makes the development of minimally invasive techniques highly relevant. MATERIALS AND METHODS: A pilot study was conducted to assess results of patients treated by sialendoscopy-assisted trans-oral approach to treat Stensen´s duct lithiasis. RESULTS: Eight patients were included; all of them operated satisfactorily. Six of them were male, and 2 were female. The mean size of the stones was 9.6 mm (Min: 6 mm/Max: 16 mm). Regarding to lithiasis location: it was anterior to the masseter line in the distal third of the Stensen's duct in seven patients and in another patient was immediately below the buccinator muscle. During the follow-up, all patients presented a healthy functioning of the gland after the compressive massage. Regarding complications, one patient presented a Stensen's duct stenosis, which required reintervention. CONCLUSION: The transoral Stensen´s duct approach represents a safe technique for lithiasis bigger than 3 mm in the distal portion of the Stensen´s duct, anterior to the Masseter Muscle line and when other minimal invasive techniques fail.

Utility of sialendoscopy in the management of juvenile recurrent parotitis. Retrospective study.

INTRODUCTION: Juvenile recurrent parotitis is a rare disease characterized by repeated episodes of inflammation affecting, unilaterally or bilaterally, the parotid glands during childhood. MATERIAL AND METHODS: Retrospective study including patients diagnosed with juvenile recurrent parotitis between January 2010 and September 2020 at a tertiary level hospital, with the aim of evaluating the results of medical treatment and sialendoscopy. RESULTS: A total of 48 patients met the inclusion criteria and had a mean follow-up of 4 years (SD = 3; Min: 2/Max: 12). Regarding treatment, 34 (70.8%) patients received conservative treatment and had a mean of 5 episodes (SD = 3; Min: 2/Max: 13) until symptom resolution. Meanwhile, 14 (29.2%) patients underwent sialendoscopy, of which two (12%) required reintervention. In 100% (14) of the patients treated with sialendoscopy, the findings were consistent with JRP and, after sialendoscopy, a statistically significant reduction in episodes was observed, with a mean of 1 post-intervention episode (SD = 1.5; Min:0/Max: 6) (P < .001). CONCLUSIONS: The results obtained in this study suggest that sialendoscopy is a useful tool in the treatment of juvenile recurrent parotitis. However, new studies comparing the results of sialendoscopy with other therapeutic alternatives are necessary.

"Omepralith": A novel simulation model for training in sialoendoscopy.

INTRODUCTION: There are no previously described training models for learning or teaching how to remove lithiasis from the salivary ducts. Therefore, we present a new simulation model to enable us to faithfully represent the process of endoscopic lithiasis extraction by sialoendoscopy. MATERIALS AND METHODS: A simulation model was developed using a pig's head, omeprazole spheres were used to simulate lithiasis in the various ducts of each salivary gland and a Dormia basket was used to train in extraction of the lithiasis model. RESULTS: Twenty-seven residents in training and/or young specialists were successfully trained in this technique using this model. Twenty-six (96.3%) considered the model useful for training in the use of baskets; all of them were able to capture the omeprazole sphere in the salivary duct. A satisfaction rate of 92.25 out of 100 points was obtained through an anonymous survey. CONCLUSION: We describe a novel simulation model using omeprazole spheres, which allows the surgeon to practice how to diagnose and treat obstructive pathology of the salivary glands in a risk-free environment guaranteeing the reproducibility of the technique in conditions similar to those of normal practice.

A Pilot Study to Assess the Sialendoscopy-Assisted Transfacial Approach in Parotid Gland Sialolithiasis.

INTRODUCTION: Twenty percent of the total lithiasis that affect a major salivary gland will be found in the parotid gland. An exclusive sialoendoscopic approach has achieved success rates close to 80%. In a significant percentage of these remaining cases, combined transfacial approaches assisted by sialendoscopy are presented as an option to be taken into account. PATIENTS AND METHODS: A prospective analysis of cases treated by combined transfacial approach assisted by sialendoscopy for lithiasis of the parotid gland and the impact of the facial nerve stimulator used during surgery. RESULTS: Five patients were included; all of them operated satisfactorily. In 4 of them, the approach proposed by McGurk and modified by Capaccio was used, and in 1 of them, the approach proposed by Nahlieli was used. We suffered a complication in just case due to the appearance of postoperative sialocele. CONCLUSION: According to our results and those previously published, the transfacial approach assisted by sialendoscopy can be considered a useful technique. Proper planning ensures an optimal result in the treatment of parotid gland lithiasis. The use of facial nerve stimulator guarantees extra security when working near to a branch of the facial nerve is suspected.

Laser-Assisted Lithotripsy With Sialendoscopy: Systematic Review of YO-IFOS Head and Neck Study Group.

INTRODUCTION: Sialolithiasis is the most common cause of symptomatic obstructive sialadenitis. Sialendoscopy represent a minimally invasive technique that has evolved significantly in the last 2 decades, with high success rates in managing sialolithiasis and allowing gland preservation. Lithotripsy assisted or not by laser represents the fragmentation of stone or lithiasis within the salivary duct followed immediately by removal of the fragmented pieces. Material and Methods: A systematic review investigating the role of laser-assisted lithotripsy with sialendoscopy (LAS) in the treatment of sialolithiasis was performed. RESULTS: Sixteen papers meet inclusion criteria. The mean maximum diameter of lithiasis was 7.11 mm (min: 2 mm/max: 17 mm; standard deviation [SD]: 2.33; 95% CI = 1.573-4.463). Success rate described ranging from 71% to 100% with a mean of 87.3% (SD: 7.21; 95% CI: 5.326-11.158) and the gland preservation rate was 97%. Considering only "non retrievable-non floating stones" studies that include both parotid and submandibular stones: Eight clinical retrospectives, nonrandomized studies and 1 prospective, nonrandomized study report results from parotid and submandibular gland lithiasis. According to this, the most common gland involved was the submandibular gland (n = 153; 65.1%), in comparison to the parotid gland (n = 82; 34.8%). CONCLUSION: The current evidence supports LAS as a conservative, efficient, safe, and gland-preserving alternative technique, in experienced hands, for management of mid-size sialolith removal from major salivary glands, when the indication is appropriate.

Intraoperative monitoring of the facial nerve during parotid gland surgery in Otolaryngology services - Head and Neck Surgery. / Monitorización intraoperatoria del nervio facial durante la cirugía de la glándula parótida en servicios de otorrinolaringología - cirugía de cabeza y cuello.

INTRODUCTION: Facial nerve injury remains the most severe complication of parotid gland surgery. Due to the increasing evidence about the advantage of the use of intraoperative facial nerve monitoring, a survey was distributed among members of the Spanish Society of Otorhinolaryngology-Head and Neck Surgery with the objective of determining patterns of its use. MATERIAL AND METHODS: A questionnaire which included 12 separate questions in 3 sections was distributed via email through the official email of the Spanish Society of Otorhinolaryngology-Head and Neck Surgery. The first section of questions was in relation to demographic characteristics, the second section was related to the pattern of monitoring use and the third section referred to litigation related to facial palsy. RESULTS: 1544 anonymous questionnaires were emailed. 255 surveys were returned, giving an overall response rate of 16.5%. From these, 233 (91.3%) respondents perform parotid gland surgery. Two-hundred nineteen (94%) respondents use intraoperative facial nerve monitoring. Of the respondents,94% used intraoperative facial nerve monitoring if in their current practice they performed fewer than 10 parotidectomies per year and 93.8% if they performed more than 10 (OR, 1.02; 95% CI, 0.68-1.45; p=.991). With regard to lawsuits, just 3 (1.2%) of the respondents had a history of a parotid gland surgery-associated lawsuit and in just one case the facial nerve monitor was not used. CONCLUSION: Our data demonstrate that most otolaryngologists in Spain use intraoperative facial nerve monitoring during parotid gland surgery. Almost all of them use it to improve patient safety and consider that facial nerve monitoring should be helpful preventing inadvertent injury.

Subjective evaluation of smell and taste dysfunction in patients with mild COVID-19 in Spain.

BACKGROUND: Has been described the loss of smell and taste as onset symptoms in SARS-CoV-2. The objective of this study was to investigate the prevalence in Spain. METHODS: Prospective study of COVID-19 confirmed patients through RT-PCR in Spain. Patients completed olfactory and gustatory questionnaires. RESULTS: A total of 1043 patients with mild COVID-19 disease. The mean age was 39 ±â€¯12 years. 826 patients (79.2%) described smell disorder, 662 (63.4%) as a total loss and 164 (15.7%) partial. 718 patients (68.8%) noticed some grade of taste dysfunction. There was a significant association between both disorders (p < 0.001). The olfactory dysfunction was the first symptom in 17.1%. The sQOD-NS scores were significantly lower in patients with a total loss compare to normosmic or hyposmic individuals (p = 0.001). Female were significantly more affected by olfactory and gustatory dysfunctions (p < 0.001). The early olfactory recover in 462 clinically cured patients was 315 (68.2%), during the first 4 weeks. CONCLUSION: The sudden onset smell and/or taste dysfunction should be considered highly suspicious for COVID-19 infection.

Transoral Sialolitectomy as an Alternative to Submaxilectomy in the Treatment of Submaxillary Sialolithiasis.

INTRODUCTION: Sialolithiasis is the most common pathology in the submaxillary gland. The introduction of minimally invasive techniques isolated or associated with sialoendoscopy is replacing glandular resection as a treatment. The conservation of the gland is justified by the recovery of function and a low recurrence rate. The rate of complications is lower in conservative techniques than in submandibular gland resection. PATIENTS AND METHODS: Thirty-three patients with fixed stones in the hilum of the submaxillary gland were treated by transoral sialolitectomy between July 2015 and July 2018, demographic data of the patients such as the number of stones, size, time of hospital stay, complications, pre- and postoperative lingual nerve function, and lithiasis recurrence were collected. RESULTS: The average volume of the stones was 1.02 cm. Complete removal of the stone was possible in 32 patients. All the patients were operated in the outpatient clinic. Seven (21%) patients reported some degree of alteration of the lingual nerve function, of which the only one presented a persistence of more than 4 weeks due to an inadvertent injury that required a microsurgical anastomosis. CONCLUSIONS: Transoral sialolitectomy is a reproducible technique with good results and lower complication rates than submandibular gland resection. Our results in the first 33 cases encourage us to maintain the combined techniques as standard in the treatment of submaxillary sialolithiasis. Current experience guides the definitive substitution of submandibular gland resection by conservative techniques in obstructive pathology.

Transoral sialolitectomy combined with sialoendoscopy versus open submaxilectomy for the management of hilar lithiasis of the submandibular gland. / Sialolitectomía transoral combinada con sialoendoscopia versus submaxilectomía abierta para el manejo de litiasis hiliares de la glándula submaxilar.

INTRODUCTION: The treatment of salivary obstructive pathology by minimally invasive techniques has been an object of assessment by different studies for decades. Lithiasis at the level of the salivary duct will be the most frequent cause of obstruction, representing more than 50% of the pathology of the major salivary glands and almost 80% of these affecting the Wharton duct. MATERIAL AND METHODS: A prospective study comparing the results of combined transoral sialolitectomy (CTS) and open submaxillectomy techniques by cervicotomy in 2 groups of patients treated by lithiasis at the level of the hilum of the submaxillary gland. RESULTS: 22 patients were included in the study 16 (72.7%) were men and 6 (27.3%) were women, the average age was 54.41 years ± 12.75 (Min: 30/Max: 77). Regarding the variables associated with the disease: average lithiasis, size of the stone, hospital stay, lingual nerve alteration or complications for both techniques, differences were not found between both groups. There were only statistically significant differences in the average stay in favor of the CTS (P=.001). CONCLUSION: The minimally invasive approaches to the salivary ductal system, associated or not with sialoendoscopy, can be efficacy and can be associated with lower number of complications. The natural tendency should be aimed to gradually replacing open sialoadenectomy techniques, reserving its indication for the treatment of tumor pathology.
