Abstract： After catching a cold,a 42-year-old male experienced acute onset of progressive hoarseness and persistent cough.His primary physician prescribed a course of antibiotics for laryngitis which turned out ineffective.His symptoms persisted for about 6 months and a vocal fold lesion was suspected.So he was admitted to the Peking University Third Hospital.The patient denied pharyngalgia,dysphagia,dyspnea,fever,or weight loss in the past 6 months.He had smoked for more than 20 years,two packs a day.Indirect and flexible laryngoscope revealed a pink exophytic mass with a narrow base on the middle third of right vocal fold.The neoplasm had a smooth surface with a diameter of about 10 mm [Figure 1].The movement of the vocal fold was normal,and no abnormality was found in the nasopharynx or oropharynx,except for some non-specific chronic inflammation signs.No superficial lymph node was palpable.Taken together all the clinical information,a benign lesion such as polyp was presumed.So without a biopsy,a direct suspension laryngoscopy was performed under general anesthesia.The lesion was resected with CO2 laser following the phonomicrosurgery principle.
