OBJECTIVES Prospective evaluation of tracheo-carinal airway reconstructions using pedicled extrathoracic muscle flaps for closing airway defects after non-circumferential resections and after carinal resections as part of the reconstruction for alleviation of anastomotic tension. METHODS From January 1996 to June 2006, 41 patients underwent tracheo-carinal airway reconstructions using 45 extr...

background: uterine rupture at the site of a previous cesarean scar is an uncommon but catastrophic complication of pregnancy, which is associated with significant maternal and fetal morbidity and mortality. case presentation: a 30-year old woman at 24th week of gestation and complaint of pain, contractions and spotting was admitted in royan institute in tehran, iran. she had a past medical his...

PURPOSE The aim of the present randomized controlled clinical study was to test whether small bony dehiscence defects (≤5 mm) left to heal spontaneously result in the same clinical and radiological outcome as defects treated with guided bone regeneration (GBR). MATERIALS AND METHODS Twenty-two patients who received at least one implant with a small bony dehiscence defect were enrolled in the ...

OBJECTIVES/HYPOTHESIS Spontaneous nasal cerebrospinal fluid (CSF) fistula represents a rare clinical entity. The possible etiology and the localization of the rhinorrhea remain an ongoing clinical challenge. The purpose of this study was to evaluate the localization of spontaneous CSF fistula and to correlate it with anatomical studies. STUDY DESIGN Retrospective clinical study, prospective a...

OBJECTIVE Soft tissue (ST) dehiscence with graft exposure is a frequent complication of vertical augmentation. Flap dehiscence is caused by failure to achieve tension-free primary wound closure and by the impairment of flap microcirculation due to surgical trauma. Soft tissue expansion (STE) increases ST quality and quantity prior to reconstructive surgery. We hypothesized that flap preconditio...

OBJECTIVE In the presence of acute inflammation and necrosis of the wall, tracheo-bronchial defects are difficult to manage. The absence of adequate vascularization and the contaminated area prevent successful direct re-suturing. METHODS In order to restore a sufficient blood supply we used a pedicled latissimus dorsi or a pectoralis major flap that was entered into the thorax after a 10-cm r...

The repair of ventral hernia defects of the abdominal wall challenges both general and plastic surgeons. Ventral herniation is a postoperative complication in 10 percent of abdominal surgeries; the repair of such defects has a recurrence rate as high as 50 percent. The "components separation" technique has successfully decreased the recurrence rates of ventral abdominal hernias. However, this t...

Objectives Describe the use of the supraclavicular artery flap for reconstruction of lateral skull and scalp defects. Discuss advantages and potential limitations of the supraclavicular artery flap. Design Case series. Setting Tertiary care academic medical center. Participants Patients undergoing lateral scalp and skull base resections. Main Outcome Measures Effectiveness in reconstructing lat...

Background: Surgical site infections (SSI) are a frequent and significant problem understudied in infants operated for abdominal birth defects. Different forms of SSIs exist, namely wound infection, dehiscence, anastomotic leakage, post-operative peritonitis fistula development. These complications can extend hospital stay, surge medical costs increase mortality. If the incidence was known, it ...

The aim of this study was to evaluate an osteopromotive technique, using a bioabsorbable membrane, for its ability to restitute bone over buccal fenestration and dehiscence defects following fixture installation. 11 patients requiring dental implant treatment and exhibiting sufficient vertical height of the maxilla and compromised bucco-palatal dimensions, as determined clinically and radiograp...
