The Effect of Liquid Nitrogen on Bone Graft Survival.

Liquid nitrogen is used in medicine for cancer treatment and tissue preservation; however, bone viability after its application is controversial. This study aims to evaluate both the tissue viability and the clinical and histopathologic findings following liquid nitrogen application with different thawing techniques in rats. Mandibular bone grafts were taken from 45 Wistar rats and freezed in liquid nitrogen for 20 minutes.

Comparison of bone prefabrication with vascularized periosteal flaps, hydroxyapatite, and bioactive glass in rats.

Background: Periosteal flaps possess osteoprogenitor cells and an osteoinductive potential that can be further augmented by combination with a biodegradable scaffold; therefore, various osteoconductive and osteostimulative biomaterials are frequently combined with periosteal flaps in studies of bone prefabrication. An experimental study was designed to determine and compare the contribution of bioactive glass and hydroxyapatite to osteoneogenesis in rats when combined with a periosteal flap.

Materials And Methods: In 60 Sprague Dawley rats, saphenous artery periosto-fasciocutaneous island flaps were transposed to abdomen.

Microvascular anastomosis using Ankaferd blood stopper: demonstration of long-term histopathologic effects on vascular tissue.

Ankaferd blood stopper (ABS) (Ankaferd İlaç Kozmetik A.Ş., Turkey) is a medicinal plant extract, which is used in Turkish traditional medicine as a haemostatic agent.

Delayed reduction of a displaced zygomatic arch fracture by external traction.

An easy and useful method designed for the reduction of delayed and displaced zygomatic arch fractures used by the treatment of a 33-year-old female patient is presented.

Superficial musculoaponeurotic system flap for reconstruction of the intraoral defects.

Intraoral tumors are the main causes of the intraoral and maxillofacial defects. Skin grafts and several soft tissue flaps can be used to reconstruct the intraoral defects including local, regional, and free flaps. Here we present a case of intraoral adenocystic carcinoma treated with segmental maxillectomy, resection of the parotid gland, and the buccal mucosa leaving a full-thickness intraoral defect.

Duplication of the mandible in Klippel-Feil syndrome.

The duplication of the mandible is an extremely rare case, which was first described by McLaughlin in 1948 as a case report of duplication of the mouth, the tongue and the mandible. Betty in 1956 and Davies in 1973 reported similar cases. The duplication of the mandible may be associated with the Klippel-Feil syndrome (KFS).

Anterior pillarplasty: a modification in cleft palate repair.

After the primary repair of cleft palate, surgeons are frequently confronted with a short soft palate and a wide velopharyngeal space, both of which are known to diminish the quality of speech. We introduce a new modification of the primary repair of cleft palate that lengthens the soft palate and helps to reduce the volume of the velopharyngeal space. Ten patients younger than 12 months with nonsyndromic cleft palate were operated on with this technique.

Injury patterns and psychological traits of patients with self-inflicted wounds produced by punching glass.

Background: Self-inflicted injuries are among the preventable forms of hand injury. Psychologic factors underlying these injuries have not been studied sufficiently. This study aims to reveal the extent of injury and the morbidity as well as the psychologic factors in a population of patients who intentionally injured themselves by punching glass.

Lipofibromatous hamartoma of the median nerve.

Lipofibromatous hamartoma is a rare tumor-like overgrowth of fibroadipose tissue surrounding the nerves. Most commonly, it involves the median nerve. The tumor is usually present at birth and grows very slowly.

A new alternative for reconstruction of soft triangle defects secondary to burn injury: superiorly based columellar flap.

Nasal reconstruction following severe burn injury remains a challenge in plastic surgery. In burn patients, the external nares and the soft triangle are commonly affected subunits of the nose where local tissue deficit and scar contraction during the recovery period contribute to soft triangle deformity and alar stenosis. These patients usually have associated facial burns with varying severity, which significantly limit the availability of local flaps.

A rare complication after septoplasty procedure in a misdiagnosed submucous cleft palate case: palatal fistula.

Nasal septoplasty is a common and low-risk procedure performed very frequently in plastic surgery as well as in otorhinolaryngology. The development of a palatal perforation following a nasal septoplasty procedure is a very rare event with only a few cases reported in the literature. A patient with palatal fistula formation after septoplasty procedure is presented here, who was later on diagnosed with submucous cleft palate during the repair of the palatal fistula.

The effects of the size of liposuction cannula on adipocyte survival and the optimum temperature for fat graft storage: an experimental study.

Background: Determining the most advantageous size of liposuction cannula and injection needles in terms of adipocyte viability could help to increase fat graft survival. When recurrent injections are necessary, storing fat tissue which is harvested during the first operation could be a practical solution if it is stored at an appropriate temperature providing the highest amount of viable fat cells.

Methods: Fat tissue was removed from the abdomen of 10 consecutive female patients by 6-, 4- and 2-mm-diameter liposuction cannulas.

Septocolumellar suture in closed rhinoplasty.

Several surgeons advise a variety of tip sutures and describe their own techniques in open approach. Septocolumellar suture is one of them and can be described as a loop suture between the medial crura and caudal septum. Although some of the articles mention that it can be applied in closed rhinoplasty, there is no description of the technical details.

Patients' perspectives on the ocular symptoms of facial paralysis after gold weight implantation.

Upper lid loading for the treatment of lagophthalmos resulting from facial paralysis is a simple and effective procedure with relatively few side effects and complications. A detailed patient-based self assessment, focusing on subjective complaints after upper lid weight implantation is scarce. In this study, a population of facial palsy patients with lid weights is asked about their subjective complaints in order to find out the patients' point of view.

Computed tomography in the management of cervical lymph node pathology.

Computerised tomography (CT) is a useful adjunct in the diagnosis of cervical pathology in head and neck carcinoma. However, different criteria used in CT analysis make the comparison of outcome studies difficult. This study compares two different CT criteria (two different lymph node sizes) for detection of cervical lymph node pathology for head and neck tumours in the same patient population.

Atypical midline cleft with duplication of the metopic suture.

Introduction: In contrast to the common clefts of the lip, alveolus and palate, the atypical clefts of the face may come in myriad patterns of clinical expression and are often not easy to define.

Purpose: In this report, a case of median craniofacial dysraphia is described.

Patient: At presentation, the 3-month-old male patient had a bilateral complete cleft of the lip, alveolus and palate.

Patients' and surgeons' perspectives on the scar components after inferior pedicle breast reduction surgery.

Background: Scarring is the most frequent cause of dissatisfaction both for the surgeons and for the patients in breast reduction surgery. Some of the techniques used today use the classic inverted T scar. An inverted T scar is a combination of three separate scars (periareolar, vertical, and inframammary).

Comparison of preoperative anxiety in reconstructive and cosmetic surgery patients.

Surgery is a serious stressor and a cause of anxiety for the patients. Reconstructive surgery patients are mostly operated on because of certain functional impairment or disability; on the contrary, cosmetic surgery patients do not have any physical impairment and they are operated on because of mostly psychologic reasons. The aim of this study was to compare the anxiety levels in the reconstructive surgery patients and cosmetic surgery patients preoperatively.

Reconstruction of the weight-bearing surface of the foot with nonneurosensory free flaps.

Neurotized fasciocutaneous flaps and split-skin grafted muscle flaps are the most frequently used free flap alternatives for the reconstruction of weight-bearing surfaces of the foot. An objective comparison of the innate characteristics of these two flap types, with respect to long-term stability, has not been possible because sensory reinnervation in the fasciocutaneous flaps has been a confounding factor. This study compares nonsensate fasciocutaneous flaps (n = 9) with nonsensate split-skin grafted muscle flaps (n = 11), with mean follow-up periods of 34.

Medial pedicled orbicularis oculi flap.

Resurfacing of the medial canthal region and bony nasal dorsum is a problem frequently encountered after tumor excisions. Traditional flaps used in this region from the glabellar and frontal areas are bulky, and donor site scar may be unsightly. A medial pedicled orbicularis oculi myocutaneous flap is an alternative.
