«Omepralith»: un modelo de simulación novedoso para el entrenamiento en sialoendoscopia

IntroductionThere 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 methodsA 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.ResultsTwenty-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.ConclusionWe 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.     

Therapeutic efficacy of intense pulsed light in patients with refractory meibomian gland dysfunction

Purpose

To evaluate the efficacy and safety of intense pulsed light (IPL) combined with meibomian gland expression (MGX) for treatment of refractory meibomian gland dysfunction (MGD).

Surgical management of deep lobe parotid tumours with and without involvement of the parapharyngeal space

The diagnosis and treatment of deep lobe parotid tumours is challenging because of the complex surgical accessibility. There is a lack of studies describing the differences between deep lobe tumours that do and do not occupy the parapharyngeal space (PPS). Patients treated for deep lobe tumours occupying the PPS (PPS group) and not occupying the PPS (non-PPS group) were analysed retrospectively. A total of 227 patients were treated surgically for deep lobe parotid tumours between 1990 and 2019. Sixty patients (26.4%) presented with tumours that involved the PPS (PPS group), while 167 (73.6%) presented with tumours that did not occupy the PPS (non-PPS group). The majority of the PPS group tumours were removed using a transcervical or transcervical–transparotid approach. PPS group tumours were larger (P < 0.001), and tumour spill occurred more frequently in this group (benign tumours: P = 0.002; malignant tumours: P = 0.033). Complication rates did not differ between the PPS and non-PPS groups. A transcervical or transcervical–transparotid approach is the preferred method for the management of deep lobe parotid tumours that occupy the PPS in our practice. Tumour spill occurred more frequently in the PPS group, which is most probably due to the larger tumour size and more complex accessibility.
