IMPORTANCE Provides an approach to osseous free flap selection for reconstruction of segmental mandible defects that takes into consideration general medical status of the patient and reconstruction requirements; demonstrates the complementary qualities of fibular and subscapular system free flaps; and describes the different surgical indications for lateral border scapular and scapular tip fre...

Background: Breast cancer is the most prevalent in our surgical practice Egypt. Seroma one of annoying complications after modified radical mastectomy and axillary clearance. Different modalities have been used to decrease incidence seroma. Objective: To assess impact using gelfoam decreasing seroma formation following mastectomy. Patients methods: This randomized controlled trial was done on...

Different reconstruction techniques of the anterior and middle skull base as consequence of a defect after surgical treatment of neoplastic pathologies are described in the literature. The aim of the present study is to present our experience regarding the use of microvascular free flaps for reconstruction of the anterior or middle skull base after large defects caused by removal of malignant n...

The authors present an overview of the various techniques which can be used to achieve coverage of exposed bone, particularly in cases of bone exposure associated with an underlying fracture or osteomyelitis. Adequate debridement, possibly in several stages, is necessary in all cases to prepare the receptor site for the next step which is soft tissue coverage, achieved using various types of su...

there have been sparse reports in literature of avulsion and degloving injuries of individual areas of face like the nose, eyelids, ear and even mandible. hemi-facial degloving is extremely rare. we present a case of post-assault degloving of the nose, part of forehead with anterior wall of frontal sinus, entire upper and lower eyelids and the cheek. proper planning and staging of the surgical ...

In the title compound, C(11)H(13)NO(4), the isoxazolidine ring has an envelope conformation with the O atom as the flap. In the crystal, mol-ecules are liked via N-H⋯O and bifurcated O-H⋯(O,N) hydrogen bonds forming chains propagating along [010]. There are also C-H⋯O inter-actions present.

In the title compound, C(12)H(10)O(4), the five-membered ring adopts an envelope conformation, with the Csp(3) atom at the flap [deviation = 0.145 (2) Å]. In the crystal structure, mol-ecules are linked by inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.

In the title compound, C(23)H(23)NO(5), the C(5)N ring adopts an envelope conformation with a C atom as the flap, whilst the saturated C(6) ring fused to it adopts a chair conformation. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops.
