Glottic hemangioma is a benign vascular tumor that is rarely seen in the adult population. We report a rare Filipino case of glottic hemangioma in a 65-year-old female presenting with 2 weeks history of hoarseness and a smooth, pedunculated, bluish mass at the anterior one-third of the right vocal cord in flexible laryngoscopy. Direct suspension laryngoscopy showed a pedunculated mass that was paler-looking, similar to the color of the surrounding mucosa, exhibiting the Phonation sign of Menzel. The patient underwent microlaryngeal excision and histopathology showed findings consistent with cavernous hemangioma.

Aspiration, the entry of material into the airway below the true vocal folds, has been reported in various type of postsurgical head and neck patients. The important of correctly identifying the cause of aspiration in the head and neck surgical patient. Clearly each cause represents a different physiologic or anatomic disorder which requires different management strategy. We discuss about the cause of aspiration during head and neck treatment.

BACKGROUND AND OBJECTIVES: Examining vibrations of the vocal fold is very important in patients with voice changes. The newly developed videokymography (VKG) takes images in real time and records irregular vibrations of the vocal fold. However, there are few data on VKG findings. We studied VKG to evaluate the vibratory characteristics of the vocal fold in benign vocal fold lesions and normal subjects. MATERIALS AND METHODS: Normal subjects (N=20) and patients (N=100) with laryngeal lesions were evaluated. Unique vibratory patterns, blurred demarcation of the mucosal propagation, decreased margin amplitudes, asymmetry in phase or amplitude, and different contact sites were observed in each benign vocal-fold lesion. RESULTS: There were several differences between subjects with normal and with laryngeal lesion. VKG depicted the tiny difference which were not exactly found by the stroboscope. CONCLUSIONS: We found that each type of laryngeal lesion has specific characteristics which can be revealed by VKG examination. These characteristics could be quantified and used to objectively evaluate VKG findings. This research shows that VKG can be used as a supplementary diagnostic tool.
