Figure 1. Design of the Estlander flap intraoperatively (immediately postresection by ENT).

In recent developments in the repair of large surgical defects where simple flap rotation may have been previously employed, myocutaneous flaps are being used because of functional advantages and to decrease the number of reconstructive procedures. The authors have employed myocutaneous flaps in 40 cases from January 1980 until April 1985 at Presbyterian Medical Center in Chonju. The primary di...

In the title compound, C(17)H(19)NO(3), the isoxazolidine ring adopts an envelope conformation with the O atom as the flap. In the crystal, O-H⋯O hydrogen bonds form C(2) (3)(14) R(2) (2)(14) motifs.

The title compound, C14H14BrNO4, contains a tricyclic ring system including three contiguous stereocenters all of which exhibit an R configuration. The cyclo-hexa-none ring adopts a chair conformation. The central oxane ring assumes a strained envelope conformation, with five of the ring atoms being nearly coplanar with the bromo-phenyl group and with the C atom adjacent to the O atom and fused...

The title compound, C(14)H(14)BrNO(5), has two chiral C atoms. The quaternary C atom in the oxolanone ring has an S configuration, while the adjacent tertiary C atom has an R configuration. The oxolanone ring adopts an envelope conformation, with the flap C atom lying 0.298 (3) Å from the mean plane of the remaining four atoms. In the crystal, mol-ecules are connected into chains along [010] vi...

Background: Lip carcinoma is a common cancer with a good prognosis and when patients refer early in the course of disease the results of treatment are acceptable. Surgical procedures for reconstruction of lip defects are the use of remaining lip tissue, tissue from the opposite lip, adjacent cheek tissue, distant flaps and microvascular free flaps. The bitemporal (visor) flap is a regional...

Summary Background Despite continuous surgical advances, reconstruction of complex lower extremity wounds remains challenging. The indication local flaps or microsurgical free tissue transfer depends on the anatomical location and size defect, as well comorbidities general condition patient. In this study, flap distal defects was assessed, postoperative complications limb salvage were analyzed....
