RESUMO
PURPOSE: Diagnosis and management of swallowing problems in children is crucial for improvement of their health status and quality of life. This study aimed to determine the accuracy of clinical feeding assessment (CFA) as a screening test to detect aspiration in children using fibreoptic endoscopic evaluation of swallowing (FEES) as the gold standard. METHODS: A prospective study of 80 children aged below 16 years who were referred to a paediatric otolaryngology clinic for swallowing complaints was completed from 2019 to 2020. Swallowing was assessed by both CFA and FEES. Presence of any one of the following symptoms was considered positive for aspiration in CFA: cough, wet vocal quality, and respiratory distress. Aspiration on FEES was measured using the Penetration Aspiration Scale. The clinical predictors of aspiration were analysed. RESULTS: The majority of the children (78.8%) had an associated neurological condition, with cerebral palsy being the most common. CFA had a sensitivity ranging from 80% to 100% and a specificity ranging from 68% to 79% for predicting true aspiration for different food consistencies. The significant risk factors predicting aspiration (p value <0.05) were history of prior intubation (pâ=â0.009), history of nasal regurgitation (pâ=â0.002) and spasticity on examination (pâ=â0.043). CONCLUSION: This study showed that CFA can be used as a screening test in evaluation of paediatric dysphagia. In those with negative CFA, the chances of aspiration are less while those with positive CFA need further evaluation. In addition, the availability and cost-effectiveness of the test make it a good tool for screening aspiration in low-resource settings.
RESUMO
A prospective single blinded randomized control trial was conducted to study if early initiation of voice therapy after microlaryngeal produces a better voice outcome in patients with benign vocal fold lesions. METHODS: In this Patients undergoing microlaryngeal surgery for benign vocal fold lesions were recruited for the study and underwent voice evaluation and videostroboscopy preoperatively. Participants were randomised into two groups depending on the duration of voice rest-A (2 days voice rest) and B (5 days voice rest). Following the period of voice rest, voice therapy (tube phonation) was carried out for a month. Postoperative evaluation was done at 6 weeks (over telephone) and 3 months (in person visit) follow up. Outcome measures included the VHI-10, auditory-perceptual voice ratings, acoustic analysis and videostroboscopic vibratory ratings. RESULTS: Of the 50 subjects, 35 completed the follow up evaluation. The overall compliance to absolute voice rest was 43%. Among the various parameters used for voice evaluation, there was no statistically significant difference between the two groups except for jitter, where the improvement in 5 day voice rest group compared to the 2 day voice rest group was statistically significant. CONCLUSION: Prolonged voice rest after microlaryngeal surgery is difficult to comply with. As there was no significant difference between the two study groups, clinicians may prescribe a shorter duration of voice rest followed by early initiation of voice therapy after microlaryngeal surgery.
RESUMO
Neuromonitoring has proved to be a useful technique in reducing nerve injury during thyroid surgery; however, costs continue to limit its use in resource-constrained settings. This study was done to assess the functional integrity of the recurrent laryngeal nerve (RLN) during thyroid surgery using palpation assessment of posterior cricoarytenoid muscle twitch in response to RLN stimulation. Between August 2016 and July 2017, 24 patients with 47 nerves at risk (NARs) underwent thyroid surgery with visual identification and testing of 44 RLNs. The functional integrity of the RLN was checked by stimulation of the RLN. Intraoperative assessment showed 100% sensitivity and positive predictive value in predicting postoperative vocal cord function. The postoperative vocal cord assessment confirmed all 44 nerves tested to be normally functioning. The mean (standard deviation) peak-to-peak amplitude and latency of the CMAP were 0.889 (0.740)/1.336 (1.660) mV and 2.295 (0.319)/2.217 (0.393) ms for left/right side NARs, respectively, with no statistically significant difference (P > 0.05). Palpation assessment of the posterior cricoarytenoid muscle provides a simple and reliable technique for confirming integrity of the RLN. Combining palpation assessment with CMAP from the inferior constrictor muscle may help reduce potential false negative results. With the use of our in-house built device which is significantly cheaper than the commercial ones, this could be considered a low-cost alternative to current established techniques.
