The combination of dorsal nasal reconstruction and camouflage of surface irregularities is an important step in rhinoplasty. We hereby present our technique of delivering diced cartilage in combination with bone dust to the nasal dorsum using the patient's blood as a carrier. We advocate use of an autologous material (blood) as a scaffold for graft delivery, dismissing the use of a foreign material or fascial wrapping of the graft.

Frontal sinus fractures constitute 5% to 15% of maxillofacial fractures, and isolated anterior table injuries account for 33% of frontal sinus fractures. The treatment strategy of frontal sinus fractures should be individualized according to the extent of the injury. Endoscope-assisted repair without any fixation method for the treatment of mildly and moderately displaced (1-5 mm) and closed isolated anterior table frontal sinus fractures is a good alternative technique for treatment.

Early closure of cranial sutures results in various types of cranial vault deformities, named craniosynostosis. Although mostly associated with syndromic cases, bony orbit deformities such as exorbitism can be seen with various types of craniosynostosis. This condition can be associated with papilledema and besides its effect on the patient's appearance can cause subluxation of the globe, lagophthalmos or keratitis resulting in corneal ulcers and ultimately loss of vision.

Hypospadias is a congenital anomaly of the penis with an ectopic, ventrally-placed meatus due to insufficient development of the anterior urethra. Tubularisation of glanular flaps without plate incision is performed with addition of a triangular flap in order to move the meatus more distally and avoid meatal stenosis. Subcoronally, mid-shaft, and coronally placed 41 hypospadias cases were treated with the tubularisation of the glanular flaps without incision of the urethral plate, a technique similar to TIP technique.

The long-term goal of cleft palate repair is to provide normal maxillary growth and speech capacity. However, most surgical repairs of cleft palate result in areas of bone denudation on lateral aspects of the hard palate. It is widely acknowledged that palatal bone denudation and subsequent scar contracture resulting from cleft palate surgery can inhibit maxillary growth.

A complete subperichondrial and subperiosteal dissection technique during rhinoplasty may minimize soft tissue disruption, resulting in less scar tissue formation and preservation of ligamentous structures.
The authors describe their results with subperichondrial dissection of the nasal framework and manipulation of the preserved nasal ligaments.
The charts of 228 consecutive patients who underwent rhinoplasty with complete subperichondrial dissection via an open or closed approach between May 2008 and April 2011 with the senior author (BÇ) were retrospectively reviewed.

Management of temporomandibular joint (TMJ) disorders presenting with pain, restricted mouth opening, or simply asymptomatic clicking can be challenging even to the experienced surgeon. Many conservative and invasive techniques are available, but most cases can be treated by arthrocentesis of the joint locally. A simple process of joint irrigation enables lysis of intra-articular adhesions, change in the joint viscosity, and clearance of various substances in the joint fluid.

Loading the eyelid with a gold weight is a popular technique for improving closure of the eyelid in patients with facial palsy. Despite it being both safe and simple, placement of the weight into a submuscular pocket is not always successful. Ulceration of the skin, and extrusion and visibility of the implant, are quite common short or long-term complications.

Teratomas can occur in almost any region of the body and are the most common extragonadal germ cell childhood tumors. Immature teratomas in the head and neck region cause severe deformity and threat life because of several reasons. Imaging investigation (ultrasonography, computed tomography, magnetic resonance imaging) is of outmost importance for the diagnosis and preoperative planning, considering that the total surgical resection of the teratoma constitutes the treatment of choice.
