ABSTRACT
Lingual thyroid is an abnormal mass of ectopic thyroid tissue seen in base of tongue caused due to embryological aberrancy in development of thyroid gland. Most of the ectopic tissue is seen in the tongue. Their identification and proper management is essential since they may be the only functioning thyroid tissue occurring in the body. We report a case of lingual thyroid in a 40 year old female patient who was hypothyroid with posterior swelling of tongue. Tc-99 scintigraphy confirmed the clinical diagnosis and surgical excision of entire tissue was done by midline mandibular split osteotomy and patient was placed under lifelong thyroxine replacement. Follow up showed excellent results with minimum patient discomfort.

Figure 8: Excised specimen

Mentions: Routine blood investigation and Thyroid function tests carried out in the patient revealed an increased thyroid-stimulating hormone (TSH) value with decreased T3 and T4 level, confirmed that the patient was hypothyroid. Ultrasound study revealed the absence of a normal thyroid gland. Diagnosis of a lingual thyroid was made based on the site specific and characteristic nature of lingual thyroid. Surgical excision was planned under general anesthesia, we choose lip split [Figure 1] mandibulotomy procedure because this approach would provide a good wide exposure to base of tongue and also suspicion of a vascular tumor was not ruled out, miniplates were adapted and osteotomy cuts were done in the parasymphysis region in an oblique fashion [Figure 2] mylohyoid muscle was dissected and mandible was swung outward, to reach the base of the tongue, growth was exposed [Figure 3] and removed in toto [Figures 4 and 5]. The osteotomized mandible was repositioned and plated [Figure 6] and primary closure was achieved [Figure 7]. Excised specimen was sent for histopathology [Figure 8]. Postoperative period was uneventful; speech improved and dysphagia was considerably reduced.
