Microlearning is recommended to be implemented within the context of a wider teaching–learning ecosystem, especially in real working environments. Task-based learning is used in clinical education setting. This study aims at assessing the effect of an integrated approach of microlearning with task-based learning on medical students’ knowledge and performance in Ear, Nose and Throat clerkship rotation. A total of 59 final-year medical students participated in this quasi-experimental study which included two control groups (routine teaching and task-based learning methods) and one intervention group (combined microlearning and task-based learning method). Pre- and post-tests of students’ knowledge and performance were assessed through a multiple-choice question test and a Direct Observation Procedural Skills (DOPS) instrument, respectively. Performing Analysis of Covariance for knowledge post-test scores among three groups revealed significant differences (F = 3.423, p-value = 0.040) and the intervention group had the highest score. Analyzing DOPS results showed that the intervention group achieved significantly higher scores compared to the control ones for all the expected tasks (p-values = 0.001). The findings of the present study show that the combined strategy of microlearning with task-based learning is an effective clinical teaching method for enhancing medical students’ knowledge and performance in a real working environment.

Facial nerve paralysis is classified into immediate or delayed-onset palsy, and affected patients should be treated through conservative or surgical therapy. Appropriate treatment is somewhat debated as well as proper time for performing surgery. This study aimed to assess treatment outcome between conservatively and surgically treated groups and to determine the appropriate time of surgery in selected patients for surgery. Twenty-four patients from April 2008 to July 2015 were included. Performing decompression surgery within the first 2 months following the trauma accompanies a better prognosis ( p-value < 0.05). Eleven patients were managed conservatively, and 4 of them demonstrated immediate onset and 7 indicated delayed onset. Nine patients obtained normal nerve function, one patient had partial palsy, and one of them had complete palsy. There was no significant difference in the rate of recovery between types of the treatment ( p-value > 0.05). Decompression surgery is recommended in the first 2 months after the trauma for immediate onset and also complete degeneration on electroneuronography.
