Abstract
We present a case of rarely encountered laryngeal chondrosarcoma originating from the thyroid cartilage with the chief complaint swelling of the anterior neck. The histopathological examination showed a low-grade chondrosarcoma. During the operation, the mass was dissected ‘en bloc’ to the layer of the thyroid cartilage from the neck skin prior to it. In the reconstruction, to preserve the main laryngeal function, a piece of the patient's nasal septum cartilage (extracted at the same time) was fixed with titanium wire and fibrin adhesive for the reconstruction of the deficit region after thyroid cartilage excision, so that the larynx was not destroyed in the front and back direction. And this prevented the contraction of the inner laryngeal muscles (TA in particular) from being limited for adhesion of the muscles to the surrounding grafted soft tissue. A rectus abdominis musculocutaneous (RAMC) free flap was selected as the reconstruction material for the excised anterior neck region. The right superior thyroideal artery and vein were used as the recipient vessels. The good condition of the transplanted tissue and no evidence of glottic stenosis made it possible for the patient to eat orally about 2 weeks later without misswallowing. He was discharged about 1 month after the operation. At the present time, after more than 3.5 years, no problems of recurrence, laryngeal function or appearance have been found. There were not many past reports of cases to guide us in the examination and treatment of this case, and we hesitated over our decision of the method of operation. A greater number of case reports will be come available thanks to it, and these might make it easier for us to select a more universal treatment (operation in particular) method for this disease.
