Reconstructive Management of Gunshot Wounds to the Frontal Sinus: An Urban Trauma Center's Perspective.

INTRODUCTION: In the last decade, we have seen a steady increase in the incidence of frontal sinus trauma due to gunshot wounds and a decrease in motor vehicle trauma. Penetrating gunshot wounds to the frontal sinus present a unique challenge to the reconstructive surgeon because they require careful consideration of the management principles of plastic surgery. Despite previous reviews on frontal sinus trauma, there are no studies examining the management techniques of frontal sinus fractures due specifically to gunshot wounds. In this study, we aim to retrospectively evaluate the use of a variety of tissue flaps in intervention and associated outcomes. METHODS: A retrospective chart review was completed on all patients with gunshot wound(s) to the frontal sinus from January 2010 to January 2018 at a single institution. The patients were classified based on the fracture pattern (anterior vs posterior table vs both), degree of displacement, presence of nasofrontal outflow tract injury, and evidence of cerebrospinal fluid leak. Patients were then stratified according to the type of reconstruction performed (cranialization, obliteration and need for free flap) and evaluated for major and minor complications after reconstruction. RESULTS: In this study, we present outcome data from 28 cases of frontal sinus trauma due to gunshot wounds. There was a statistically significant difference (P = 0.049) in the type reconstructive strategy employed with each type of flap, with pericranial flaps primarily used in cranialization, temporal grafts were more likely to be used in obliteration, and free flaps were more likely to be used in cranialization. The overall major complication rate was 52% (P = 0.248), with the most common acute major complication was cerebrospinal fluid leak (39%) and major chronic was abscess (23.5%). CONCLUSIONS: This report explores the management of frontal sinus trauma and presents short-term outcomes of treatment for penetrating gunshot wounds at a tertiary referral center.

Immediate Latissimus Dorsi and Prosthetic Reconstruction in the Setting of Postmastectomy Radiation: An Analysis of 376 Breast Reconstructions.

BACKGROUND: In immediate breast reconstruction, the plastic surgeon must strive to create an aesthetically pleasing result while minimizing complications. The latissimus dorsi (LD) myocutaneous flap has long been used a workhorse flap in breast reconstruction. Often times, it is used a salvage flap after other methods of breast reconstruction have failed. In this study, we review the use of this flap in conjunction with prosthetic devices, regardless of the need for adjuvant radiation, to determine the safety and efficacy of this approach as a primary method of reconstruction. METHODS: A single surgeon practice with a standardized reconstructive algorithm was reviewed. This compromises a 2-stage approach involving the use of LD myocutaneous flaps and tissue expanders for immediate reconstruction after mastectomy, followed by exchange for implants at a secondary surgery. A retrospective chart review was performed on 201 patients (376 breast reconstructions) who met inclusion criteria. Patient demographics and outcomes were compared based on radiation status. The primary outcome, reconstructive success, was defined as no need for further autologous reconstruction beyond the 2-stage approach utilized. RESULTS: Statistical analysis was performed on both patient demographics, complications, and reconstructive outcomes. Demographics were equivalent between the 2 groups. When analyzing complications and outcomes, there was no difference between nonradiated patients and radiated patients except when looking at reconstructive loss, which was 3.6% in the nonradiated group and 16.6% in the radiated group (P = 0.03). However, one third of the patients in the radiated group who had reconstructive losses were due to reasons not related to radiation therapy. Taking this into account, overall reconstructive success showed no statistical significance between the 2 groups. CONCLUSIONS: The findings from this study show that immediate reconstruction with LD myocutaneous flaps in conjunction with prosthetic devices is a reliable and safe option, even in the setting of adjuvant radiation therapy, as the autologous tissue mitigates many sequelae of radiation therapy. Not only does this type of reconstruction provide an aesthetically pleasing result in 2 stages, but also has a favorable complication profile and success rate.

Point-of-care ultrasound diagnosis of flexor tenosynovitis caused by an unusual pathogen.

Skin and soft tissue infections are commonly encountered in the emergency department and are typically caused by common gram-positive bacteria. In the immunocompromised patient, however, infections from unusual pathogens should also be considered. We describe the case of a 66-year-old male with a history of renal transplant who was diagnosed with flexor tenosynovitis by point-of-care ultrasound. Although initial wound cultures were negative, subsequent microbiological testing led to the underlying cause, a nontuberculous mycobacterial infection.

An Assessment of Margins after Lumpectomy in Breast Cancer Management.

We performed this study to evaluate our indications for margin re-excision (MRE) in the management of cancer patients opting for breast conservation therapy (BCT). We identified patients choosing breast conservation therapy from January 2012 to May 2014. Margins were considered negative if >2 mm, close if <2 mm, and positive if ink was detected abutting tumor. Patients with close and positive margins underwent MRE. We identified 247 patients of which 190 had negative margins and did not require MRE, 46 patients had a close margin, and 11 had a positive margin, leading to an MRE rate of 23 per cent (57 of 247). The following variables were evaluated: tumor size, stage, estrogen receptor, progesterone receptor, HER2/neu receptor, and node status. None predicted the presence of tumor in the MRE specimen (P > 0.05). Patients with close margins had a 6.5 per cent (3 of 46), and patients with positive margins had a 36.4 per cent (4 of 11) incidence of tumor in the MRE specimens; this difference was statistically significant (P = 0.02). The low rate of finding tumor in MRE specimens of patients with close margins after lumpectomy for breast carcinoma argues for limiting MRE to patients with positive margins (ink on tumor) only. We have adopted this approach in our institution.
