Although laryngeal tuberculosis is not frequent, it still occurs with an increasing incidence of pulmonary tuberculosis. Clinical pattern and spread mechanism of this disease have also changed as well. This study was performed to examine the current propensity seen in laryngeal tuberculosis and the clinical characteristics of this disease in patients showing atypical clinical pattern. The medical and videostroboscopic records of 60 patients with laryngeal tuberculosis diagnosed from the year 1994 to 2004 at the department of otorhinolaryngology in Severance Hospital were analyzed. The age of the patients ranged from 25 to 78 years, with their average age being 49.7 years. The ratio between men and women was 1.9:1. The major symptom encountered was hoarseness (96.6%). Clinically, granulomatous (n=22) and ulcerative types (n=11) of laryngeal tuberculosis were still prevalent, however, the incidence of atypical types such as polypoid (n=16) and nonspecific (n=11) were on the rise. Among the 27 cases that showed polypoid or nonspecific types, unilateral lesion was seen in 20 cases (74%). The most frequently affected area by this disease was true vocal cord, followed by false vocal cord, epiglottis, arytenoids and posterior commissure. Active pulmonary tuberculosis was present in 28 (46.7%), inactive pulmonary tuberculosis in 20 (33.3%), normal lung status in 12 cases (20%). Primary laryngeal tuberculosis was present in 9 cases (15%). Single lesion, polypoid and nonspecific type were prevalent in patients with inactive tuberculosis or normal lungs status. Physicians should be aware of the changes in the clinical pattern of laryngeal tuberculosis, which poses serious complications and risk of spreading.

To determine whether level IIb lymph nodes can be saved in elective supraomohyoid neck dissection (SOHND) as a treatment for patients with squamous cell carcinoma of the oral cavity. Design: Prospective analysis of a case series. Setting: University hospital. Patients and Interventions: From 1997 to 2001, 74 patients with squamous cell carcinoma of the oral cavity and with no palpable lymph nodes at the neck who underwent an elective SOHND were prospectively studied. Main Outcome Measures: The incidence of pathological metastasis to level IIb lymph nodes and the regional recurrence within this area after elective SOHND was performed were evaluated. Results: Of the 74 patients, 24 (32%) had lymph nodes positive for microscopic metastatic squamous cell carcinoma. Four (5%) of the 74 patients had involvement of level IIb lymph nodes. There was no instance of isolated metastasis to level IIb lymph nodes without involvement of other nodes in the SOHND specimens. There were 6 cases of the ipsilateral neck recurrences, and of these, 2 patients (3% of all patients) developed recurrences in the level II lymph nodes. Conclusions: Level IIb lymph node metastasis was rare in this study, and nodal recurrence in this area after SOHND in squamous cell carcinoma of the oral cavity was infrequent. Therefore, this region may be preserved in elective SOHND in patients with squamous cell carcinoma of the oral cavity.
