OBJECTIVES: Buccal mucosa grafts and fascio-cutaneous flaps are frequently used in long anterior urethral strictures (1). The inlay and onlay buccal mucosa grafts are easier to perform, do not need urethral mobilization and generally have good long-term results (2-4). In the present video, we present a case where we used a double buccal mucosa graft technique in a simultaneous penile and bulbar urethral stricture. MATERIALS AND METHODS: A 54 year-old male patient was submitted to appendectomy where a urethral catheter was used for two days in May 2015...

BACKGROUND: Reconstruction of posterior thoracic and trunk defects can prove challenging even to the most seasoned surgeons. Many commonly used techniques for closing back defects include primary closure and split skin grafts. Often times, however, other techniques are needed in order to give the patient the best aesthetic and functional outcome. In this study, we focus on and evaluate donor site closure techniques for defects in the back created by harvesting scapular and parascapular flaps...

BACKGROUND: In modern rhinoplasty, septal cartilage is the most commonly used graft material. It is a big challenge if septal cartilage is insufficient. We present an alternative technique named the "rabbit flap," created from the cephalic portion of the lower lateral cartilage to show its effectiveness on nasolabial angle, nasal axis deviation, and nasal dorsal line. METHODS: An alternative flap, called a "rabbit flap," is constituted from the cephalic portion of the lower lateral cartilage (LLC)...

OBJECTIVE Competency in endoscopic endonasal approaches (EEAs) to repair high-flow cerebrospinal fluid (CSF) leaks is an essential component of the neurosurgical training process. The objective of this study was to demonstrate the feasibility of a simulation model for EEA repair of anterior skull base CSF leaks. METHODS Human cadaveric specimens were utilized with a perfusion system to simulate a high-flow CSF leak. Neurological surgery residents (postgraduate year 3 or greater) performed a standard EEA to repair a CSF leak using a combination of fat, fascia lata, and pedicled nasoseptal flaps...

Predicting the dispersal of pest insects is important for pest management schemes. Flight-mills provide a simple way to evaluate the flight potential of insects, but there are several complications in relating tethered-flight to natural flight. We used high-speed video to evaluate the effect of flight-mill design on flight of the red palm weevil (Rynchophorous ferruginneus) in four variants of a flight-mill. Two variants had the rotating radial arm pivoted on the main shaft of the rotation axis, allowing freedom to elevate the arm as the insect applied lift force...

We report a case of free flap deterioration which may have been induced by pressure gradient resulting from cranial defect overlying a ventriculoperitoneal shunt (VP shunt). The patient, male and aged 78, had a VP shunt operation for progressive hydrocephalus. Afterwards, the scalp skin flap surrounding the VP shunt collapsed and showed signs of necrosis, exposing part of the shunt catheter. After covering the defect with a radial forearm free flap, the free flap site showed signs of gradual sinking while the vascularity of the flap remained unimpaired...

Background: Amputation is commonly performed for toe necrosis secondary to peripheral vascular diseases, such as diabetes mellitus. When amputating a necrotic toe, preservation of the bony structure is important for preventing the collapse of adjacent digits into the amputated space. However, in the popular terminal Syme's amputation technique, partial amputation of the distal phalanx could cause increased tension on the wound margin. Herein, we introduce a new way to resect sufficient bony structure while maintaining the normal length, based on a morphological analysis of the toes...

Local flaps exhibit excellent color matching that no other type of flap can compete with. Moreover, surgery using a local flap is easier and faster than surgery using a distant or free flap. However, local flaps can be much more difficult to design. We designed 2 templates to plan a V-Y rotation advancement flap. The template for a unilateral V-Y rotation advancement flap was used on the face (n=5), anterior tibia (n=1), posterior axilla (n=1), ischium (n=1), and trochanter (n=2). The template for a bilateral flap was used on the sacrum (n=8), arm (n=1), and anterior tibia (n=1)...

BACKGROUND: Using a sinus tarsi rotational flap is an uncommon approach to treating chronic open infective lateral malleolus bursitis. METHODS: We treated eight patients, including six males, using this approach. First, we debrided all the infected tissues and used a negative pressure wound closure system where needed. After acute infection had been controlled, the local rotational flap was used for cases where the wound could not be closed by a simple suture or bone exposure...

Rehabilitation following ablative skull base surgery remains a challenging task, given the complexity of the anatomical region, despite the recent advances in reconstructive surgery. Remnant defects following resection of skull base tumors are often not amenable to primary closure. As such, numerous techniques have been described for reconstruction, including local rotational muscle flaps, pedicled flaps with skin paddle, or even free tissue transfer. However, not all patients are appropriate surgical candidates and therefore may instead benefit from nonsurgical options for functional and aesthetic restoration...

The goals of reconstruction following any oncologic extirpation are preservation of function, restoration of cosmesis, and avoidance of morbidity. Anatomically, the lateral skull base is complex and conceptually intricate due to its three-dimensional morphology. The temporal bone articulates with five other cranial bones and forms many sutures and foramina through which pass critical neural and vascular structures. Remnant defects following resection of lateral skull base tumors are often not amenable to primary closure...

In this paper, brain-machine interface (BMI) was adopted to investigate the motor area in the animal brain. Stainless steel wire electrodes were implanted to search the brain area for rotation, forward movement, and flapping. In continuation of our search for optimized coordinates for stimulation, we designed electrode case for safer transport and for a more accurate fabrication of the electrode array. The cases are customized for each set of coordinates, and quickly built using a 3D printer. The case reduced the surgery time and increased accuracy in electrode placement...

Gastrocnemius flaps have been used for decades to reconstruct defects of the proximal tibia and knee. They have proven to be useful in the soft-tissue reconstruction of defects caused by trauma, tumors, and infections about the knee, and the reconstruction of extensor mechanism discontinuity with and without total joint arthroplasty. The flaps have low failure rates and a distinct proximally based blood supply that allows them to be elevated and rotated up to 15 cm above the level of the knee joint. The vascular anatomy is reproducible because rotational flaps do not require microvascular anastomosis...

Browning et al describe procedures for prevention of incontinence in women undergoing obstetric fistula (OF) repair or treatment of women who have residual incontinence after successful fistula closure. Their premise is that scarring and decreased elasticity of the anterior vagina results in opposing forces on the urethra thereby causing incontinence-the so called Integral Theory. By employing a rotational skin flap from the adjacent thigh, the vaginal wall elasticity is restored. Their technique does not include the fascial portion of the flap which is widely considered to be important for preservation of the blood supply...

BACKGROUND: To report the recurrence rate for an anchored conjunctival rotation flap technique in primary pterygium surgery. METHODS: Primary pterygium surgeries performed using anchored conjunctival rotation flap techniques (110 eyes in 110 patients) with a minimum follow-up of 12 months were reviewed. In this technique, a conjunctival flap is rotated to cover the bare sclera and suture-fixated with either 8-0 polyglactin (41 eyes) or 10-0 nylon (69 eyes). The recurrence rate was determined, and the two suture materials utilized were compared...

BACKGROUND: Cleft lip repair aims to create symmetric nasolabial morphology with minimal scarring. Poor aesthetic outcomes may have damaging psychosocial implications. Determining the optimal method of recreating lip symmetry is a major goal of applied cleft clinical research. This study aims to determine whether subjective assessment could differentiate aesthetic outcome between two surgeons who use two different surgical techniques for unilateral cleft lip repair. METHODS: Surgeon A uses a modified rotation-advancement technique incorporating a supra-white roll flap and Noordhoff-style vermilion flap...
