Adenoid cystic carcinoma formerly called cylindroma is rare tracheal tumor. Characteristics of adenoid cystic carcinoma are infiltrative nature with local recurrence tendency and long natural course of the disease. Adenoid cystic carcinomas develop most commonly in the trachea. Primary resection and end-to-end anastomosis of the involved airway are treatment of choice. And postoperative radiation therapy might be useful, particularly when the surgical margins are not ample. We report two cases of adenoid cystic carcinoma of trachea diagnosed by flow-volume curve.

Reconstruction of various defects following head and neck surgery is crucial for restoring both function and aesthetics. Over the years, various flap techniques have been developed to meet these demands. The supraclavicular artery flap is a versatile option readily accessible within the same surgical field during head and neck surgery. Its similarity in texture, color, and contour to the facial region makes it particularly useful for reconstructing defects in the neck and lower face. Additionally, its thin and pliable nature, coupled with a moderate volume, renders it suitable for a wide range of applications, including intraoral defects, pharyngeal defects, and contour refinement in facial surgery. In this paper, we present a method for reconstructing defects in the head and neck region using the supraclavicular artery flap, and discuss its utility, advantages, and limitations.
