Myringoplasty is a procedure which deals on repair of the tympanic membrane. This procedure can be done via postaural, endaural or endomeatal route. Various grafts such as temporalis fascia, vein graft, perichondrium are used. The technique can be categorized as underlay, overlay, interlay or its combination depending on the placement of the graft material. This study was done to compare underlay, overlay and combined technique in terms of the closure of the membrane defect, postoperative complications and over all success rates. Apart from few complications, this study revealed over all success rate was best with combined technique but the difference was not significant statistically when the methods are comparable among them.
Introduction
Ectopic thyroid is a rare congenital condition. Dual ectopic thyroid is rarer still with only 30 cases reported in literature. The most common location is the lingual or sublingual region followed by the hyoid region. Instances of dual ectopic thyroid with one in lingual region and the other in mediastinum are very few.
Case Report
A case of dual ectopic thyroid is presented with absent normal thyroid in a girl of 14 years who presented with difficulty in swallowing and lump sensation in throat. Ultrasound, MRI scan and Technetium 99m pertechnetate thyroid scan were done. She showed lingual thyroid and thyroid tissue in upper mediastinum and no thyroid tissue in the normal anatomical location.
Discussion
The discovery of mediastinal ectopic thyroid was incidental. She had subclinical hypothyroidism and was treated with thyroxine replacement therapy.
