Laryngeal chondroma: a benign process with long-term clinical implications.

Chondroma of the laryngeal cartilage is a rare, benign neoplasm which can manifest as a neck mass or, if situated within the airway, as slowly progressive obstruction, hoarseness or dyspnea. The most common location for chondroma is the posterior lamina of the cricoid cartilage; the next most common locations are the thyroid, arytenoid and epiglottic cartilages. Chondroma and low-grade chondrosarcoma are difficult to distinguish from one another histologically. Although chondrosarcoma reportedly recurs, local surgical excision without radical margins and with long-term clinical follow-up is recommended. We report one case of thyroid cartilage chondroma and include a review of radiologic studies and histopathologic analysis results. We also report a second case with severe airway obstruction caused by a large cricoid chondroma. A review of the English language biomedical literature on laryngeal chondroma is included.

The Rintala flap revisited.

We describe nasal tip reconstruction using a superiorly based midline Rintala flap. Good tissue coverage and excellent flap viability, color match, and nasal contour make this flap a good alternative for reconstructing large nasal tip defects without using forehead flaps. Up to half the superior columella can be reconstructed simultaneously by using this single-stage technique with the patient under local anesthesia. Adjunctive procedures such as tip rhinoplasty and bilateral cheek flap advancement can add to the utility of this flap and are discussed along with general techniques and case examples.
