The Zagreb method of partial laryngectomy: a retrospective study 1970-1986.

The Zagreb method of partial laryngectomy is an original method of laryngeal reconstruction following tumor extirpation using the sternohyoid muscle fascia. This material is distant from the immediate tumor site, resistant to infection, saliva and shrivelling, thus being very appropriate for covering major laryngeal defects. Statistical data analysis included clinical records from 1970, when the method was introduced at ENT Department, Zagreb School of Medicine, till 1986. During the study period, 574 patients were admitted for operative treatment of laryngeal carcinoma, and the partial method was employed in 350 (61%) of them. This percentage has generally remained unchanged to the present, because the use of fascia has extended the partial procedure applications and subsequent reconstruction. This has allowed a more extensive tumor excision without strictly following classical horizontal and vertical laryngectomy, with the additional use of so-called partial laryngectomy on demand. Records on the follow-up (5-20 years) after this type of surgery revealed an 87% survival rate (n = 304).
