RESUMEN
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.

PURPOSE: Chronic obstructive sialadenitis (COS) is a recurring inflammation of the salivary gland. To date, there are no known predisposing factors for COS. Given the advances seen in radiology and sialendoscopy, we must update our knowledge of COS, analyzing factors that can favor its development. METHODS: We prospectively analyzed 333 patients who underwent sialendoscopy between 2012 and 2021. Epidemiologic, radiologic, and sialendoscopy-related factors were correlated. Suspected diagnosis was established based on the clinical and radiologic data. The final diagnosis was determined on the basis of sialendoscopic findings. RESULTS: The most common etiology of COS was stricture (40.8%). Lack of papilla distensibility (LPD) was also described as an etiology. COS was related to patient gender and age. Submandibular gland involvement was significantly more associated with lithiasis and LPD, while COS of the parotid gland was most frequently caused by stricture. Radioiodine sialadenitis and Sjögren's syndrome were significantly associated with stricture. MR sialography (MR-Si) showed the best overall sensitivity and specificity. CONCLUSION: In our series, stricture was the most common cause of COS. We describe LPD as a frequent cause of COS in this series; ours is the first study to report this finding. There was a significant association between the salivary gland involved, patient sex and age, and the cause of COS. MR-Si showed the greatest diagnostic yield.

BACKGROUND: Accessory submandibular gland is a very rare anatomical variant. There have been only 6 reported cases of this entity in the English literature, only 1 of which was identified using magnetic resonance imaging. METHODS: We report the case of a 39-year-old female with symptoms of left submandibular sialoadenitis who was diagnosed of sialolithiasis within the left accessory submandibular gland by magnetic resonance sialography (MR-Si). RESULTS: The calculus was palpated near the submandibular papilla and was extracted by an intraoral approach. One-year follow-up revealed no evidence of recurrence. CONCLUSIONS: This is the first case reported to date in the English literature of a patient with sialolithiasis within an accessory submandibular gland diagnosed by MR-Si.
RESUMEN
Although greater trochanter pain syndrome (GTPS) is a prevalent cause of musculoskeletal pain in the general population, there is lack of imaging studies searching for differential features of inflammatory enthesitis in GTPS. We analyzed the features of GTPS using sonography and magnetic resonance imaging (MRI) to identify useful differential signs between spondyloarthritis (SpA) and other inflammatory or non-inflammatory musculoskeletal diseases. All patients with unilateral GTPS attended by our Arthritis Unit between February 2011 and March 2012 were included. Patients were classified as having SpA or mechanical (without inflammatory musculoskeletal disease) GTPS. Rheumatoid arthritis (RA) patients were also included as inflammatory controls. Ultrasound scans of the painful and contralateral, asymptomatic, greater trochanter were made. We assessed the gluteus medius and gluteus minimus tendons for signs suggestive of tendinopathy. Random MRI of the same regions was made in a subgroup of patients to validate the ultrasound findings. A total of 107 patients with unilateral GTPS were included, of whom 96 were female, with a mean age of 61.6 years: 34 had SpA, 48 had non-inflammatory musculoskeletal disease, and 25 had RA. No specific sonographic features for SpA were found. Pathological findings were more frequent in patients without musculoskeletal inflammatory disease (mainly bursitis and erosions). A large number of alterations were found in the asymptomatic side (around 40 % had cortical irregularities and 20 % bursa effusion). Signs of enthesopathy were more prevalent in the gluteus minimus tendon, regardless of the diagnosis (54.2 % had erosions, 39.3 % bursitis, 38.3 % calcifications and 37.4 % tendinosis). No patient had power Doppler signal. Age was the main factor in the appearance of tendinopathy. MRI confirmed the changes detected by ultrasound in all 40 patients evaluated. GTPS in patients with SpA has similar sonographic findings to those observed in patients with RA and patients without musculoskeletal inflammatory disease. Neither sonography nor MRI was clinically useful in classifying GTPS as a manifestation of SpA.

Intraorbital foreign bodies are located within the orbit but outside the ocular globe. Though not uncommon, removal of these objects poses a challenge for surgeons. External approaches have been the most frequently used but are associated with increased complications and morbidity. An endoscopic endonasal approach can be an appropriate and less complicated technique in these cases. We report a case of a chronic intraorbital foreign body located within the medial extraconal space lateral to the lamina papyracea and behind the lacrimonasal duct, which was successfully removed using a transnasal, transethmoidal endoscopic technique. Neither postoperative complications nor ocular impairment was reported. The patient improved and remains asymptomatic. The transnasal transethmoidal endoscopic approach can be used as a safer and less invasive alternative when removing foreign bodies from the medial orbital compartment.
