<p><strong>Background:</strong>  Pain is the most common complaint in the immediate post-tonsillectomy period. Inadequate post-tonsillectomy pain management has many drawbacks. Ropivacaine is a new long acting local anaesthetic, structurally closely related to bupivacaine.</p><p><strong>Methods: </strong>It was a prospective double blinded randomized control trial on a total of 50 patients who were posted for tonsillectomy. Randomization of each patient was done into two groups one of which had received 4 ml of 0.5% ropivacaine hydrochloride solution and other 4 ml normal saline. Data entry and analysis was done with (SPSS IBM) version 21.0. Both univariate and bivariate analysis done. Proportions were calculated for qualitative variables and mean with standard deviation was done for quantitative variables. Required tests of significance such as Chi square test and independent test were applied. Significance of p value is taken as p&lt;0.05. Postoperative pain, first post op oral intake, duration of post-operative hospital stay, and postoperative haemorrhage was assessed. The intensity of postoperative pain was assessed on behavioural observational pain Scale and Wong baker faces pain rating scale.</p><p><strong>Results:</strong> Pre-incisional infiltration of 0.5% Ropivacaine was an effective method to reduce post-operative pain in patients undergoing tonsillectomy under GA. Effect of  Ropivacaine was statistically significant (p&lt;0.05).</p><p><strong>Conclusions:</strong> We recommend the use of 0.5% ropivacaine pre-incisional infiltration in patients undergoing tonsillectomy.</p>

<p class="abstract"><strong>Background:</strong> The P300 was among the first auditory response in a collection of events related or endogenous evoked responses. The P300 is related to cognition and use of knowledge about the environment.</p><p class="abstract"><strong>Methods:</strong> The subjects (n=60) selected with an equal distribution of genders. P300 evoked potentials elicited by non-speech and speech stimuli is recorded.  </p><p class="abstract"><strong>Results:</strong> There is a significant difference in latency of P300 for speech verses non-speech stimuli as well as there is a significant difference in the latency of P300 among males and females for speech versus non speech stimuli. No significant difference in amplitude of P300 for speech versus non-speech stimuli and for right versus left ears.</p><p class="abstract"><strong>Conclusions:</strong> P300 latency is influenced by stimulus used and gender variation. The present study showed that the non-speech stimuli had lower latencies compared with speech stimuli. For the P300 amplitude values, the difference between groups were not significant.</p>

<p class="abstract"><strong>Background:</strong> The purpose of this study was to find the effect of chronic rhinosinusitis on dental malocclusion.  A malocclusion is defined as an irregularity of the teeth or a mal relationship of the dental arches beyond the range of what is accepted as normal. Malocclusion may not be life-threatening, but it is an important public health issue as it compromises the health of oral tissues and also can lead to psychological and social problems. There are numerous studies in the literature about prevalence of the dental malocclusion but there is no study regarding association of CRS and malocclusion. Several factors related to malocclusion, such as anterior crowding, midline malalignment, and facial asymmetry, have strong effects on the perception of facial aesthetics, which influence the psychological development and in turn, influence social acceptance and self‑perception.</p><p class="abstract"><strong>Methods:</strong> This was a prospective cross-sectional observational study was conducted from September 2015 to August 2017 and 57 patients with diagnosis of having chronic sinusitis, were evaluated for dental occlusion. Malocclusion is then classified by angle’s classification.  </p><p class="abstract"><strong>Results:</strong> Most patients of chronic rhinosinusitis had dental malocclusion in grade II, followed by grade I, then     grade III.</p><p class="abstract"><strong>Conclusions:</strong> While treating the patients of CRS one must keep in mind that he may have class II malocclusion which may cause gum disease, poor oral hygiene, impaired speech, mastication and aesthetics of face and need orthodontics management as well.</p>
