Computer guided calvarial bone grafting for reconstruction of orbital floor blow out fracture.

Background: Calvarial grafts represents a superior option for orbital floor reconstruction, however the difficulty of intraoperative moulding and placement remains as a major limitation. We used patient specific guides and sterolithographic models to facilitate this procedure.

Methods: The study was conducted on 10 patients with orbital floor blow out fracture.

Patient-specific PEEK implants for immediate restoration of temporal fossa after maxillary reconstruction with temporalis muscle flap.

Background: Temporal hollowing is a common complication following the rotation of the temporalis muscle that leaves the patient with a cosmetic impairment. Several alloplastic materials have been used to reconstruct the donor site; however, these implants need meticulous adaptation to conform the periphery of the defect and restore the contour of the temporal area. The aim of this study was to assess the use of patient-specific polyetheretherketone (PEEK) temporal implants to prevent temporal hollowing following the use of full temporalis muscle flap for large maxillary defects reconstruction.

Alveolar Cleft Reconstruction Using Double Iliac Corticocancellous Bone Plates Grafting Technique in Mixed Dentition Phase.

Objective: The primary goal of maxillary alveolar cleft reconstruction in patients with cleft lip/palate at the phase of mixed dentition is to build bone in the cleft area which in turn allows closure of the oronasal fistula, establishes arch continuity, and improve maxillary stability. This study aimed to evaluate the double iliac corticocancellous bone plates grafting technique for initial alveolar cleft grafting.

Design: This prospective study was conducted on 12 consecutive patients with unilateral complete alveolar cleft and previous cleft lip and palate corrective surgery.

Dorsal versus ventral strip augmented anastomotic bulbar urethroplasty: retrospective study.

Purpose: The published literature shows controversies with regard to the treatment of choice for longer stricture. Augmented anastomotic urethroplasty (AAU) was described for long bulbar urethral strictures with an extended area of narrowing and fibrosis, the technique combines the advantages of both anastomosis and graft substitution. We aimed to compare the dorsal and ventral strip anastomosis in the AAU.

The Effect of Orthognathic Surgery on Osteoprotegerin as Immunological Caliper of Bone Healing.

Background: Osteoprotegerin (OPG) is considered to be the cytokine that plays an important role in the healing process. OPG regulates bone cell biology, osteoblast-osteoclast, bone-immune cross-talk and maintenance of bone mass. It plays an important role in the development, induction, and repair of bone.

Grafted tubularised incised-plate urethroplasty: An objective assessment of outcome with lessons learnt from surgical experience with 263 cases.

Objective: Snodgrass urethroplasty remains the preferred technique in primary distal hypospadias but development of meatal stenosis often limits distal extension of the midline incision of the urethral plate (MIUP), which remains a limiting factor in reconstructing an apical neomeatus (NM). We here-in assess the cosmetic and functional outcome with distal extension of the MIUP in grafted tubularised incised-plate urethroplasty (G-TIP) repair.

Patients And Methods: This prospective study included the surgical experience of 263 cases of primary hypospadias operated upon between 2012 and 2015.
