<p class="abstract"><strong>Background:</strong> Thyroglossal duct cysts are the most common midline neck swellings. They are routinely treated by surgeons with simple excision.</p><p class="abstract"><strong>Methods:</strong> We present a retrospective study of a series of 30 cases operated in our hospital over a period of five years and the challenges faced during investigations, surgery and postoperative period. All patients were clinically diagnosed as thyroglossal duct cysts. The diagnosis confirmed with USG Neck and FNAC of the swelling. CECT NECK was used to delineate the normal thyroid and patients were subjected to Sistrunk procedure under general anesthesia.</p><p class="abstract"><strong>Results:</strong> The outcome of all cases was good with one case being a revision surgery and another case going in for delayed healing due to infection. All patients were healthy with no complaints postoperatively.</p><p class="abstract"><strong>Conclusions:</strong> This study validates the Sistrunk surgery as the best method of excision to avoid recurrences. This article highlights the variant presentations of this cyst in our institution and the challenges we faced in diagnosis, during surgery and later as well.</p>

<p class="abstract"><strong>Background:</strong> Neurotology forms the grey area between otologists and neurologists. Vertigo is also a complex symptom that often has multiple pathologies leading to the presentation. Electronystagmography is a complex investigation that cannot be comprehended by many other doctors. The Claussens butterfly chart offers a simple pictoral representation of the caloric test that can be easily and immediately Understood by patients and other doctors.</p><p class="abstract"><strong>Methods:</strong> 50 patients presenting to the Neurotology OPD with complaints of vertigo were subjected to this investigation and the butterfly chart derived. The correlation between the clinical diagnosis and the butterfly chart patterns studied.  </p><p class="abstract"><strong>Results:</strong> The sensitivity and specificity of the butterfly code for central lesions is 75% and 73% respectively. The sensitivity and specificity of the butterfly code for peripheral lesions is 64.3% and 50% respectively.</p><p class="abstract"><strong>Conclusions:</strong> The butterfly chart is a very simple and useful investigation that can help classify the etiology of vertigo as central or peripheral and thus help in treatment. It is also the only investigation that is helpful to localize the side of lesion in vertigo of any etiology.</p>
