RESUMEN
INTRODUCTION: We investigated complications and recurrence rates after surgical techniques for sialolith removal with intact and resected Wharton's duct of the submandibular gland. METHODS: The retrospective case-control analysis of a series analysed 271 surgical operations (2003-2022) for sialolithiasis performed at a hospital department of Otolaryngology-Head and Neck Surgery. The study compared two approaches: (1) pure endoscopic technique or pinpoint stone removal with Wharton's duct left intact and (2) transoral duct dissection or pinpoint stone removal technique, after which the duct was shortened. While choosing the surgical option, the size of the stone, the location of the stone, and the presence of multiple stones were taken into account. The rates of complications (lingual nerve paraesthesia, duct stenosis, drooling, and sialoadenitis), the incidence of foreign bodies, and the rate of recurrence during follow-up of ≥18 months were compared. RESULTS: 323 sialoliths were removed from 271 patients. Of these 323 calculi, 150 were removed by the first approach and 173 by the second approach. The calculi varied in diameter from 2 to 38 mm with an average diameter of 8.2 mm. For all 271 patients, the rate of recurrence was 4.8%, but 11 recurrent cases (8.7%) appeared after the first approach surgeries and 2 cases (1.4%) after the second approach surgeries (p = .03). Other variables did not show statistically significant differences. CONCLUSIONS: Surgical removal of the submandibular calculi, ending with shortening of Wharton's duct, reduces the recurrence rate for sialolithiasis but does not affect the rate of postsurgical complications.

The aim of this study was to propose a treatment strategy for intraglandular submandibular calculi based on calculus site. Seventy-three consecutive patients with impalpable intraglandular submandibular calculi were enrolled retrospectively. The calculi were classified as either post-hilar type, central type, or superficial type. Treatment approaches included transoral duct slitting (TDS), interventional basket retrieval (IBR), intraductal laser lithotripsy (ILL), and transcervical lithotomy (TCL). Complete calculus removal with gland preservation was achieved in 64 patients (87.7%). The success rate for post-hilar, central, and superficial calculi was 86.4% (51/59), 90.9% (10/11), and 100% (3/3), respectively. The treatment approach applied in patients with treatment success was TDS in 32 cases, IBR in 20, ILL in nine, and TCL in three. During follow-up (median 17.3 months), one patient experienced gland atrophy and three had ductal stenosis; the remaining 60 patients (93.8%, 60/64) had good clinical outcomes. In the eight failure cases operated by TDS, the deeply situated calculi could not be detached despite the parenchymal incision in five cases, while the procedure was ceased due to the patient's inability to cooperate in the other three cases. In the remaining failure case, the submandibular gland was sacrificed after calculus extraction via TCL. Application of the proposed treatment algorithm might help preserve gland function in patients with intraglandular submandibular calculi.

Importance: Refractory sialorrhea in children can result in pulmonary aspiration and irreversible lung damage. Despite many studies devoted to the surgical treatment of sialorrhea, there is a paucity of objective outcome measures after surgery, especially with regard to pulmonary health. Objectives: To assess whether bilateral submandibular gland excision and bilateral parotid duct ligation ("DROOL" procedure) is associated with reduced pulmonary inflammation in bronchoalveolar lavage (BAL) samples after surgery and to assess patient factors associated with improvement after surgery. Design, Setting, and Participants: This retrospective case series included all 112 patients undergoing the DROOL procedure at a single tertiary care pediatric children's hospital from January 1, 2012, to December 31, 2021. Statistical analysis was performed from March 30 to June 10, 2023, and August 20 to September 23, 2023. Exposure: DROOL procedure for refractory sialorrhea. Main Outcomes and Measures: Degree of pulmonary inflammation (neutrophil percentage) according to BAL cytologic findings and overall bronchoscopy findings up to 12 months before and after the DROOL procedure. Secondary outcomes included number of annual hospitalizations, caregiver report of function before and after the procedure, and need for revision procedures and/or additional operations for secretion management. Results: A total of 112 patients (median age, 3.4 years [IQR, 2.0-7.1 years]; 65 boys [58.0%]) underwent DROOL procedures and had both preoperative and postoperative BAL samples during the study period. Patients demonstrated objective improvement in pulmonary inflammation after surgery, with the median polymorphonuclear neutrophil percentage decreasing from 65.0% (IQR, 14.0%-86.0%) before the surgery to 32.5% (IQR, 3.0%-76.5%) after the surgery (median difference in percentage points, -9.0 [95% CI, -20.0 to 0.0]). Prior to the DROOL procedure, 34 patients (30.4%; 95% CI, 21.8%-38.9%) were hospitalized 2 or more times annually for respiratory illness, which decreased to 10.1% (11 of 109; 95% CI, 4.4%-15.7%) after surgery (3 patients did not have hospitalization data available following surgery). Most caretakers (73 [65.2%]) reported improved secretion management after the procedure. Conclusions and Relevance: This study suggests that patients with impaired secretion management who underwent a DROOL procedure demonstrated improvement in pulmonary inflammation and a reduction in hospitalizations after surgery. Caretakers were also likely to report subjective improvement in secretion management and quality of life. Additional research is necessary to guide optimal timing and patient selection for this procedure.

BACKGROUND: Thread lifting is a common minimally invasive plastic surgery procedure. Parotid gland injury caused by thread lifting is a known complication; however, visual evidence of this complication is lacking. OBJECTIVES: This study aimed to present cases of parotid gland injury by thread lifting shown using ultrasound and to discuss the importance of ultrasound detection of the location of the parotid gland before thread insertion. METHODS: This study included eight patients diagnosed with parotid gland perforation and one with parotid duct injury due to threads from November 2020 to October 2022. RESULTS: Six patients showed tenderness and swelling, three were asymptomatic, and one with duct injury showed severe swelling and pain. Although the severity and duration of symptoms have differed, we confirmed the progress of improvement with conservative treatment and confirmed ultrasound findings progressed. CONCLUSIONS: Using ultrasound to detect the parotid gland's location before thread lifting might reduce the chance of parotid duct injury. Identifying immediate parotid duct or gland injury with ultrasound can help to act quickly for delayed pain or swelling and reduce the likelihood of additional complications.

LITHIASIC SALIVARY GLAND PATHOLOGIES. Sialolithiasis is the most frequent pathology affecting the salivary glands. Almost 80% of these lithiasis affect the submandibular gland, in the Wharton duct whilst 20% occur in the parotid gland in the Stenon duct. The diagnosis is based on typical patient interrogation and clinical symptoms (intermittent facial swelling associated with eating, sialadenitis) and/or on paraclinical examination. Ultrasound echography is often prescribed, but CT-scan and sialo-MRI offer a more precise preoperative assessment. Minimally-invasive gland-preserving techniques such as sialendoscopy (combined or not with transoral duct surgery) are nowadays considered to be the method of first choice. These methods reach success rates above 80% and significantly reduce surgical complications and hospital stay.
PATHOLOGIES LITHIASIQUES DES GLANDES SALIVAIRES. Parmi les pathologies des glandes salivaires, les lithiases des canaux salivaires sont les plus fréquentes. Elles sont le plus souvent retrouvées dans les glandes sous-maxillaires au niveau des canaux de Wharton (80 %), et plus rarement dans les glandes parotides au niveau des canaux de Sténon (20 %). Le diagnostic repose sur l'interrogatoire et la clinique, qui peuvent être évocateurs (hernie ou coliques salivaires, sialite aiguë), et sur l'imagerie. L'échographie est un examen diagnostique très accessible, mais le scanner et la sialo-IRM permettent une évaluation préopératoire plus précise. Le traitement repose en première intention sur des traitements chirurgicaux conservateurs et mini-invasifs tels que la sialendoscopie, associée ou non à une approche transorale, qui sont efficaces dans 80 % des cas et permettent de réduire les complications postopératoires et la durée d'hospitalisation.

AIM: This study aimed to describe the diagnosis and treatment of various surgical salivary affections in buffaloes. MATERIALS AND METHODS: This study included 135 buffaloes examined at Dakahlia Governorate between 2011 and 2022 suffering from various surgical salivary affections. The recorded surgical affections had salivary fistula (n = 44), ectasia of Stenson's duct (n = 11), ranula/mucocele (n = 46), and cervical sialocele (n = 34). The buffaloes were sedated using an intramuscular injection of xylazine (0.05 mg/kg) and local infiltration analgesia of lidocaine for specific surgical interventions. RESULTS: The salivary duct fistula cases were surgically corrected using a retrograde infusion of povidone-iodine into the duct and its double ligation with Prolene following fistulectomy. Intraoral marsupialization was done in buffaloes suffering from ectasia of the parotid duct. The mucocele /ranula was surgically incised with daily flushing with povidone-iodine. The cervical sialocele was treated by giving an elliptical excision on the sialocele, and sialoadenectomy of the mandibular salivary gland was performed to facilitate dynamic fluid/saliva drainage. A 92.5% of diseased buffaloes showed an uneventful recovery without any postoperative complications after the first treatment, whereas 7.5% of animals tended to recur. The most common and almost equally distributed salivary affections recorded in adult buffaloes were parotid duct fistula, mucocele, and cervical sialocele. The Stenson's duct ectasia was commonly registered in calves, being congenital. CONCLUSION: Ranula was the most common salivary affection encountered in adult buffaloes, closely followed by parotid duct fistulae and cervical sialoceles. Stenson's duct ectasia was the least encountered salivary affection in calves and was congenital. All salivary affections were corrected easily and safely, with satisfactory outcomes.

Obstructive sialadenitis is the most common cause of non-malignant salivary gland disorders, with salivary gland strictures being responsible for approximately 23% of all benign obstructive disease. Significant advances in minimally invasive techniques, including radiologically-guided balloon sialoplasty, offer the potential for successful treatment with reduced complications. At present there is a paucity of follow-up data regarding patient outcomes and repeat interventions in those undergoing the procedure. Patients with parotid or submandibular gland sialadenitis secondary to gland stricture were identified and underwent radiologically-guided balloon sialoplasty at Queen Alexandra Hospital, Portsmouth, UK between 2015 and 2022. Patient outcomes, complications and reintervention rates were recorded prospectively over the seven-year period and analysed retrospectively. A total of 44 patients underwent radiologically-guided balloon sialoplasty. Forty (89%) underwent sialoplasty for parotid gland disease, with a minority (n = 5) receiving an intervention for submandibular gland strictures. A total of 37 (84%) had their obstruction successfully treated (82% of parotid gland obstructions and 100% of submandibular gland obstructions). Five patients (11%) required a repeat intervention. Seventeen successfully treated patients (85%) who attended follow-up clinic appointments described complete resolution of their symptoms, with the remaining three (15%) describing a partial response. Radiologically-guided balloon sialoplasty for the treatment of benign obstructive sialadenitis secondary to a gland stricture is a safe and effective method of eliminating the obstruction and relieving patients' symptoms. Most patients were symptom free at short-term follow up, with a minority requiring a second sialoplastic intervention.

OBJECTIVE(S): To confirm that hilar transoral submandibular sialolitectomy (TOSL) is the first treatment option for submandibular hilar lithiasis (SHL) in terms of glandular parenchyma recovery, salivary system restoration, and patient quality of life (QoL) improvement. METHODS: Depending on whether the stone was easily palpable, TOSL was carried out with or without sialendoscopy. For the first time in the literature, Magnetic Resonance Sialography (MR-Si) was performed before and after TOSL, to evaluate stone characteristics, glandular parenchyma status, hilum dilation and main duct recanalization. Radiological data was examined independently by two radiologists. COSQ, a recently validated and specific questionnaire, was used to assess associated QoL. RESULTS: Between 2017 and 2022, 29 TOSL patients were examined. With a high interobserver correlation, MR-Si was confirmed as a very useful radiological test in the pre- and post-surgical evaluation of SHL. The salivary main duct was completely recanalized in all cases. The presence of lithiasis was found in 4 patients (13.8%). After surgery, the majority of patients (79.31%) had hilum dilation. There was a statistically significant improvement in parenchyma status, but no significant progression to glandular atrophy. After surgery, COSQ mean values always improved (22.5 to 4.5). CONCLUSIONS: TOSL is the ideal surgical technique for the management of SHL, resulting in improved parenchymal inflammatory changes, recanalization of Wharton's duct, and enhancement patients' QoL. As a result, before removing the submandibular gland, TOSL should be considered as the first treatment option for SHL.

BACKGROUND: To investigate the value of lymph node ratio (LNR) for postoperative major salivary duct carcinoma (MSDC) and to establish a model for prognosis assessment and treatment optimization. METHODS: Data of MSDC were retrieved in public database, and prognostic factors were identified by univariate and multivariate analyses. A nomogram and risk stratification system were constructed. RESULTS: Four hundred and eleven eligible patients were included (training cohort vs. validation cohort: 287: 124). LNR ≥0.09 was associated with worse overall survival (OS). Age at diagnosis, sex, T stage, and LNR were identified as prognostic factors and integrated into nomogram. Low-risk patients were found to have better OS than high-risk patients. Furthermore, postoperative radiotherapy (PORT) significantly improved OS in the high-risk subgroup, but chemotherapy did not confer a long-term survival benefit. CONCLUSIONS: A nomogram model integrating LNR could better assess postoperative prognosis and risk stratification in MSDC, and identify patients who might benefit from PORT to avoid overtreatment.

Sialendoscopy is a minimally invasive technique used mainly in the diagnosis and treatment of obstructive salivary gland disorders. There has yet to be a report on its use in the diagnosis of metastatic disease. While metastatic cancer has been described in numerous head and neck anatomic subsites, it has not been reported to be found in a mucous plug in Stensen's duct. Sialendoscopy was performed in a 68-year-old female patient who presented with symptoms of ductal obstruction. Basket removal of a mucous plug was done and histopathological analysis of this specimen found adenocarcinoma. The overall clinical picture, imaging, and final histopathological results suggested that this patient had metastatic breast carcinoma to a mucous plug in Stensen's duct, the diagnosis of which was made with the aid of interventional sialendoscopy. This is the first report in which metastatic cancer was identified in a mucous plug in Stensen's duct. Sialendoscopy can be a useful tool to aid in the diagnosis of metastatic diseases in rare and unusual clinical situations.

Cystic lesions observed in parotid glands are relatively rare and comprise 2-5% of all parotid primaries. A salivary duct cyst (SDC) is a true cyst representing 10% of all salivary gland cysts. The risk of malignant transformation of SDC's epithelium is extremely rare. In the literature, only three cases of carcinoma ex SDC of the parotid gland are described. This report presents the first in the literature case of myoepithelial carcinoma (MECA) arising from a parotid SDC. A 75-year-old male patient was referred to the Department of Cranio-Maxillofacial Surgery of the Jagiellonian University in Cracow, Poland due to a cystic tumor arising from the right parotid gland. Superficial parotidectomy with facial nerve preservation was performed. Histological examination confirmed a rare case of MECA emerging from the SDC. The immunohistochemical profile of MECA ex SDC was presented. During 6 months of the follow-up, local recurrence or distant metastasis was not observed.

Sialolithiasis occurs in approximately 0.45% to 1.20% of the general population. The typical clinical symptom manifests as a painful swelling of the affected glands after a meal or upon salivary stimulation, which extremely affects the life quality of the patients. With the development of sialendoscopy and lithotripsy, most sialoliths can be successfully removed with preservation of the gland. However, sialoliths in the deep hilar-parenchymal submandibular ducts and impacted parotid stones located in the proximal ducts continue to pose great challenges. Our research center for salivary gland diseases (in Peking University School and Hospital of Stomatology) has used sialendoscopy for 17 years and treated >2 000 patients with salivary gland calculi. The success rate was approximately 92% for submandibular gland calculi and 95% for parotid calculi. A variety of minimally invasive surgical techniques have been applied and developed, which add substantial improvements in the treatment of refractory sialolithiasis. Further, the radiographic positioning criteria and treatment strategy are proposed for these intractable stones. Most of the hilar-parenchymal submandibular stones are successfully removed by a transoral approach, including transoral duct slitting and intraductal basket grasping, while a small portion of superficial stones can be removed by a mini-incision in submandibular area. Impacted stones located in the distal third of parotid gland ducts are removed via "peri-ostium incision", which is applied to avoid a cicatricial stenosis from a direct ostium incision. Impacted parotid stones located in the middle and proximal third of the Stensen's duct are removed via a direct mini-incision or a peri-auricular flap. A direct transcutaneous mini-incision is commonly performed under local anesthesia with an imperceptible scar, and is indicated for most of impacted stones located in the middle third, hilum and intraglandular ducts. By contrast, a peri-auricular flap is performed under general anesthesia with relatively larger operational injury of the gland parenchyma, and should be best reserved for deeper intraglandular stones. Laser lithotripsy has been applied in the treatment of sialolithiasis in the past decade, and holmium â¶YAG laser is reported to have the best therapeutic effects. During the past 3 years, our research group has performed laser lithotripsy for a few cases with intractable salivary stones. From our experiences, withdrawal of the endoscopic tip 0.5-1.0 cm away from the extremity of the laser fiber, consistent saline irrigation, and careful monitoring of gland swelling are of vital importance for avoidance of injuries of the ductal wall and the vulnerable endoscope lens during lithotripsy. Larger calculi require multiple treatment procedures. The risk of ductal stenosis can be alleviated by endoscopic dilation. In summary, appropriate use of various endoscopy-assisted lithotomy helps preserve the gland function in most of the patients with refractory sialolithiasis. Further studies are needed in the following aspects: Transcervical removal of intraglandular submandibular stones, intraductal laser lithotripsy of impacted parotid stones and deep submandibular stones, evaluation of long-term postoperative function of the affected gland, et al.

OBJECTIVE: To conduct a long-term retrospective evaluation of the safety and effectiveness of sialographic balloon dilatation in Stensen's duct stenosis (SDS). STUDY DESIGN: Retrospective cohort. SETTING: Single-institution academic tertiary referral center. METHODS: All SDS balloon dilatations (SSBDs) performed from 2011 to 2017 were monitored. Pain relief was evaluated by a numeric rating scale at 3-year follow-up at least. Long-term glandular swelling frequency patterns, quality of life (QoL), and drug consumption were retrospectively assessed. Procedure-related complications were recorded. RESULTS: Twenty-one SSBD procedures were recorded (mean ± SD age, 55 ± 12 years), all performed under local anesthesia. SSBD led to complete dilatation in 7 patients (33%), residual stenosis in 8 (38%), and no dilatation (failure) in 6 (29%). Retrospective analysis of clinical outcomes was possible for 17 patients, 71% of whom presented with long-term pain relief, at a mean relief of 3.2 points on the numeric rating scale (P < .001). Long after SSBD, patients presented with a mean decrease of 15.4 glandular swellings per month (P < .001). Medical consumption was reduced to 18% of patients taking some drugs because of SDS after SSBD vs 71% before. SSBD showed an impact on QoL in >80% of patients, with mean improvements of 26% and 25% in the percentage point reduction of physical and mental QoL, respectively (P < .001). No complications were noted except temporary discomfort due to the procedure. CONCLUSION: Despite the advent of sialendoscopy-guided techniques, SSBD should be considered for SDS treatment, as it is a safe procedure and provides sustained pain relief.

OBJECTIVE: The objective is to evaluate the long-term impact of sialendoscopic-assisted salivary duct surgery (SASDS) on sialadenitis symptoms using the Chronic Obstructive Sialadenitis Symptoms (COSS) questionnaire. METHODS: The COSS questionnaire, which scores symptoms on a 0-100 scale, was administered prospectively to adult patients pre-operatively, 1-year, and 6-years post-operatively. We examined COSS scores and categories representing complete (<10), partial (10-25), and no (>25) resolution of symptoms with attention to factors significantly associated with incomplete resolution (≥10). RESULTS: Approximately 6-years after SASDS, 111 patients reported scores for 128 symptomatic glands (72 with sialolithiasis, 56 without sialolithiasis). For glands with sialolithiasis, the median COSS score pre-SASDS was 27.5 (interquartile range [IQR]: 13.5-43), which was significantly reduced to 1.0 (IQR: 0-5.5) at 1-year and 1.5 (IQR 0-5) at 6-years postoperatively. Glands without sialolithiasis had a median COSS score of 40.5 (IQR: 23-52.5) preoperatively, that significantly reduced to 13.5 (IQR 5-21) at 1-year and 14 (IQR 6.5-25.5) at 6-years post-operatively. There was no significant difference in scores from 1- to 6-years. Intraoperative presence of sialolith, absence of stenosis, stenosis in the distal duct, and submandibular gland involvement were significant predictors of complete resolution of symptoms at 6-years. CONCLUSION: Approximately 6-years after SASDS for sialadenitis, the majority of patients have durable symptom improvement. The sialolithiasis group had higher rates of complete resolution compared to the non-sialolithiasis group. Presence of ductal stenosis on sialendoscopy, non-distal stenoses, and parotid gland involvement were risk factors for persistent long-term sialadenitis symptoms. Laryngoscope, 133:792-800, 2023.

The aim of this study was to evaluate the gland function of patients following endoscopy-assisted removal of impacted hilo-parenchymal stones in the Wharton's duct. The study cohort comprised 115 patients who had undergone successful endoscopy-assisted lithotomy for hilo-parenchymal stones (mean diameter 7.7 mm). Gland function was evaluated at a mean 12 months after surgery using ultrasonography, sialography, and/or sialometry. Postoperative ultrasonography of 51 affected glands revealed a regular gland size in 58.8%, normal parenchyma density in 51.0%, and ductal ectasia in 80.4%. Postoperative sialograms of 109 affected glands were scored as type I (approximately normal) in 13 cases, type II (saccular ectasia of the hilo-parenchymal duct with/without stenosis, and no contrast retention) in 64, type III (saccular ectasia of the hilo-parenchymal duct with/without stenosis, and mild contrast retention) in 23, and type IV (poor shape of the main duct with evident contrast retention) in nine cases. The existence of ductal ectasia corresponded well to larger stone cases (P = 0.002). In the postoperative sialometry of 35 patients with unilateral stones, differences between the two sides were insignificant (P > 0.05). For patients with hilo-parenchymal submandibular gland stones, endoscopy-assisted surgery and extended postoperative follow-up help preserve the gland with good function.
