[Recognizing of the transglottic carcinoma].
OBJECTIVE
A study was undergone about transglottic carcinoma(TGC) in eighty six cases from 1979 to 1998, so as to recognize the TGC.


METHODS
Evaluating retrospectively the procedure of the disease, surgical operations, presence of cervical metastasis, gathering the data on histopathological discovery and following up and so on.


RESULTS
The TGC was different from T2, T3 supraglottic or glottic carcinoma of larynx. In 86 TGC, there were 63 cases which were operated with total laryngectomy, 9 cases subtotal laryngectomy and 14 cases frontolateral hemilaryngectomy, 47 cases with neck dissection. In TGC which size > 2 cm, there were 58% which extend to the framework of larynx, 46% with extension out of larynx, and 71% with neck metastasis. The result of following up shows that 5-year survival rate was 55.41%, 10-year was 29.72%, 15-year and more was 18.92%.


CONCLUSIONS
There is an actual signification for TGC to be a special type of the laryngeal carcinoma. The characteristics of the precise topography of the the paraglottic space (PGS) can explain the reason of extension, spread of the TGC and cervical metastasis. Elective neck dissections and complemental radiotherapy postoperatively should be included during surgical resection.
