Sialendoscopy for the management of obstructive salivary gland disease: A systematic review and meta-analysis

Objective: To conduct a systematic review with metaanalysis to determine the efficacy and safety of sialendoscopy in the treatment of obstructive diseases of the salivary glands in adults. Data Sources: MEDLINE, EMBASE, and the Cochrane Library (no lower limit to October 2010). Reference lists were searched for identification of relevant studies. Study Selection: Prospective or retrospective studies of adult patients treated with interventional sialendoscopy for the management of salivary gland obstruction were selected. Outcome measures included rates of success (symptom-free and absence of residual obstruction), sialadenectomy, and complications. Non-English publications were excluded. Data Extraction: Two independent review authors screened eligible studies, extracted relevant data, and resolved discrepancies by consensus when applicable. Weighted pooled proportion, 95% confidence intervals, and test results for heterogeneity are reported. Data Synthesis: Twenty-nine studies were included in the analysis. The weighted pooled proportion of success rates were 0.86 (95% CI, 0.83-0.89) for studies involving 1213 patients undergoing sialendoscopy alone and 0.93 (95% CI, 0.89-0.96) for the 374 patients undergoing sialendoscopy with a combined surgical approach. Outcomes following interventional sialendoscopy for radioiodine-induced sialadenitis were reported in 3 studies, and success rates were variable. Rates of sialadenectomy were low, and few major complications were reported. Conclusion: Findings from the present systematic review and meta-analysis suggest that sialendoscopy is efficacious, safe, and gland preserving for the treatment of obstructive major salivary gland disease

Thermal burn of palate caused by microwave heated cheese-pie: A case report

A female patient, 36-years-old, complained of bilateral palatal pain on the anatomical area of upper second molars. The painful condition of palatal mucosa erosion was observed. Palatal erosions or ulcerations may be caused by heated food cooked in microwave ovens. We present a case of a bilateral palatal burn caused by cheese-pie. Concluding, any food containing cheese, when heated in microwave oven, may cause palatal burn if eaten immediately

Outcome of minimally invasive management of salivary calculi in 4,691 patients

Objective: To evaluate the application of minimally invasive techniques in the management of salivary stones. Background: The incidence of salivary calculi is 60 cases/million/year, with most stones situated in the mid or proximal duct. The current treatment of these stones is adenectomy. This paper reports the results of minimally invasive methods of stone removal that avoid gland excision. Methods: Observational study of 5,528 consecutive patients treated by lithotripsy, endoscopy, basket retrieval, and/or surgery in five centers from 1990 to 2004 inclusive. A total of 567cases were excluded, leaving 4,691 patients (parotid n=1,165, submandibular n=3,526) for analysis. Results: Salivary calculi were eliminated in 3,775/4,691 (80.5%) of cases and partly cleared in 782/4,691 (16.7%). Salivary glands were removed in 134/4,691 (2.9%) of patients with symptoms in whom treatment failed. Conclusions: Minimally invasive techniques move treatment of salivary calculi to an outpatient or a day case setting. They are reliable ways of both retrieving stones and eliminating symptoms, and mean that the gland rarely has to be removed

A Prospective Observational Study of Complications in 140 Sialendoscopies

Objectives. To evaluate the incidence and nature of complications associated with diagnostic and interventional sialendoscopies and to report intervention failures in a prospective setup. Study Design. Prospective observational study. Setting. Academic tertiary care university hospital. Subjects and Methods. Patients who underwent diagnostic or interventional sialendoscopy between October 2015 and December 2016 were prospectively enrolled. Patient data, operation-related factors, treatment failures, and complications were recorded into a database and analyzed. Results. A total of 140 sialendoscopies were attempted or performed on 118 patients; 67 (48%) were for a parotid gland and 73 (52%) for a submandibular gland. The sialendoscopy was interventional in 81 cases (58%), diagnostic in 56 (40%), and not possible to perform in 3 (2.1%). A total of 21 complications were registered for 21 sialendoscopies (15%) and 21 patients (18%). The most common complication was infection, in 9 cases (6.4%). Other observed complications were salivary duct perforation (4 cases), prolonged glandular swelling (3 cases), transient lingual nerve analgesia (2 cases), basket entrapment (2 cases), and transient weakness in the marginal branch of the facial nerve (1 case). All complications were related to interventional procedures or papilla dilatation. Failure to treat occurred in 21 (15%) sialendoscopies: sialendoscopy itself was unsuccessful in 3 cases, and an intended intervention failed in 18 cases. Conclusion. Complications in sialendoscopy are usually related to interventional procedures. The complications are mainly minor and temporary but lead to additional follow-up visits, further treatments, and sometimes hospitalization. Sialendoscopic procedures are safe but not free of complications.Peer reviewe

Double Facial Nerve Trunk Emerged from the Stylomastoid Foramen and Petrotympanic Fissure: A Case Report

There are several studies concerning branches of the facial nerve, but we encountered less information about the trunk of the facial nerve in the literature. During the routine dissection of a 65-yr-old Caucasian male cadaver, double facial nerve trunk emerged from the stylomastoid foramen and petrotympanic fissure were encountered. Because of an extremely rare variation, we presented this case report. In addition this cadaver had two buccal plexuses. These plexuses and other branches were formed to structures like to polygon. These anatomic peculiarities were described, photographed and illustrated. Finally, magnetic resonance imaging was performed by using 1.5T scanner to this cadaver. The facial nerve trunk can be damaged during surgical procedures of the parotid gland tumours and submandibular region. Surgeons who are willing to operate on this area should be aware of the possible anatomical variations of the facial nerve trunk

Oynophagia in patients after dental extraction: surface electromyography study

OBJECTIVES: Surface electromyographic (sEMG) studies were performed on 40 adult patients following extraction of lower third and second molars to research the approach and limitations of sEMG evaluation of their odynophagia complaints. METHODS: Parameters evaluated during swallowing and drinking include the timing, number of swallows per 100 cc of water, and range (amplitude) of EMG activity of m. masseter, infrahyoid and submental-submandibular group. The above mentioned variables (mean + standard deviation) were measured for the group of dental patients (n = 40) and control group of healthy adults (n = 40). RESULTS: The duration of swallows and drinking in all tests showed increase in dental patients' group, in which this tendency is statistically significant. There was no statistically significant difference between male and female adults' duration and amplitude of muscle activity during continuous drinking in both groups (p = 0.05). The mean of electric activity (in μV) of m. masseter was significantly lower in the dental patients' group in comparison with control group. The electric activity of submental-submandimular and infrahyoid muscle groups was the same in both groups. CONCLUSION: Surface EMG of swallowing is a simple and reliable noninvasive method for evaluation of odynophagia/dysphagia complaints following dental extraction with low level of discomfort of the examination. The surface EMG studies prove that dysphagia following dental extraction and molar surgery has oral origin, does not affect pharingeal segment and submental-submandibular muscle group. This type of dysphagia has clear EMG signs: increased duration of single swallow, longer drinking time, low range of electric activity of m. masseter, normal range of activity of submental-submandibular muscle group, and the "dry swalow" aftereffect. The data can be used for evaluation of complaints and symptoms, as well as for comparison purposes in pre- and postoperative stages and in EMG monitoring during treatment of post-surgical oral cavity discomfort and dysphagia

Oral vs. pharyngeal dysphagia: surface electromyography randomized study

<p>Abstract</p> <p>Background</p> <p>A clear differential diagnosis between oral and pharyngeal dysphagia remains an unsolved problem. Disorders of the oral cavity are frequently overlooked when dysphagia/odybophagia complaints are assessed. Surface electromyographic (sEMG) studies were performed on randomly assigned patients with oral and pharyngeal pathology to evaluate their dysphagia complaints for the sake of differential diagnosis.</p> <p>Methods</p> <p>Parameters evaluated during swallowing for patients after dental surgery (1: n = 62), oral infections (2: n = 49), acute tonsillitis (3: n = 66) and healthy controls (4: n = 50) included timing and amplitude of sEMG activity of masseter, infrahyoid and submental muscles.</p> <p>Results</p> <p>The duration of swallows and drinking periods was significantly increased in dental patients and was normal in patients with tonsillitis. The electric activity of masseter was significantly lower in Groups 1 and 2 in comparison with the patients with tonsillitis and controls. The submental and infrahyoid activity was normal in dental patients but infrahyoid activity in patients with tonsillitis was high.</p> <p>Conclusion</p> <p>Dysphagia following dental surgery or oral infections does not affect pharynx and submental muscles and has clear sEMG signs: increased duration of a single swallow, longer drinking time, low activity of the masseter, and normal range of submental activity. Patients with tonsillitis present hyperactivity of infrahyoid muscles. These data could be used for evaluation of symptoms when differential dental/ENT diagnosis is needed.</p
