Sensory recovery with innervated and noninnervated flaps after total lower lip reconstruction: a comparative study.

This study compares sensory recovery after total lower lip reconstruction in a wide variety of flaps including bilateral depressor anguli oris flap, submental island flap, bilateral fan flaps, radial forearm flap, and pectoralis major myocutaneous flaps in a large number of patients. Spontaneous return of flap sensation was documented by clinical testing in the majority (3%) of patients who underwent total lower lip reconstruction. Sensory recovery occurred more often in patients with fasciocutaneous free flaps than in those with musculocutaneous flaps.

Use of a perichondrial autograft on the peritendinous adhesion: an experimental study in rabbits.

Objective: The aim of this experimental study was to evaluate the use of a clinically available perichondrium graft as an adjunct to surgical tendon repair.

Methods: Eight male New Zealand white rabbits of similar height and weight were used in this study. The left and right Achilles tendons were used as the experimental and control group, respectively.

Anatomic and functional improvements achieved by rehabilitation in Zone II and Zone V flexor tendon injuries.

Objective: The aim of this study was to compare anatomic and functional improvements in zone II and zone V flexor tendon injuries and to determine the effect of injury level on disability.

Design: Seventeen patients (53 digits) with zone V and 14 patients (25 digits) with repaired zone II flexor tendon injuries were enrolled in this study. All patients were treated with Modified Kleinert protocol and followed up for a median of 60 mos.

Various applications of chondrocutaneous composite grafts in secondary cleft lip nose patients.

Composite chondrocutaneous grafts were applied to 12 patients in various forms to repair the columellar deficit, to form the nasal tubercle and nostril sill in cleft lip nose patients. Cleft lip-nose deformity patients with alar cartilage hypoplasia, obtuse angulation of the medial and lateral crura and the resulting plica vestibularis, internal nasal valve problems associated with the weakness of upper lateral cartilages are included in this study and composite conchal cartilage grafts are utilized to achieve a symmetrical and functional result.

Behavior of the different implant materials in acute infection and efficacy of antibiotherapy: experimental study in rats.

In this study, we propose a comparison of the behaviors of four different implant materials in case of acute infection: expanded polytetrafluoroethylene (e-PTFE), porous high density polyethylene (PHDPE), silicone, and autogenous cartilage tissue. The efficacy of prophylactic and therapeutic antibiotic therapies was also investigated in a rat model as four groups: group A, acute infection and no antibiotic therapy (n = 24); group B, acute infection and prophylactic antibiotic therapy (n = 24); group C, acute infection and therapeutic antibiotic therapy (n = 24); and control, no infection and no antibiotic therapy (n = 24). All materials with dimensions of approximately 1 x 1 cm(2) diameter were implanted separately under the dorsal skin of rats.

Effects of surgical or chemical delaying procedures on the survival of proximal predicled venous island flaps: an experimental study in rats.

To increase the survival of proximally pedicled venous island flaps, which are known to be safe only when small, we used surgical and chemical delaying procedures both individually and in combination for 7, 14, and 21 days. Survival was 1% in those flaps designated as controls, in which there was neither surgical nor chemical delay. However, it was 3%, 31%, and 68% at 7, 14, and 21 days, respectively, when surgical delay was used and 16%, 56%, and 86%, at 7, 14, and 21 days, respectively, when chemical delay was used.

Prefabricated nasolabial flap for reconstruction of full-thickness distal nasal defects.

Background: The reconstruction of full-thickness nasal tip and alar defects is challenging owing to the distal nose's triple-layer structure: skin, cartilage, and mucosa.

Objective: In the reconstruction of wounds of the distal half of the nose involving the rim, the most important issue to be considered is to provide a good functional and an acceptable esthetic result. Various local and distant flaps have been described for this purpose.

What should be the treatment modality in giant cutaneous lipomas? Review of the literature and report of 4 cases.

We present three females (20, 39 and 58 years old) and one male patient (47 years old), admitted to our clinic with 3-20 years history of giant lipomas on periscapular (n = 2), posterior cervical (n = 1) and abdominal areas (n = 1), respectively. The sizes of the tumours ranged from 15 x 14 cm(2) to 35 x 25 cm(2) weighing 1900-12 350 g. In all cases, the diagnosis of the lesions was by physical examination and confirmed with computed tomography, magnetic resonance imaging and ultrasonography.

Idiopathic isolated clitoromegaly: A report of two cases.

BACKGROUND: Clitoromegaly is a frequent congenital malformation, but acquired clitoral enlargement is relatively rare. METHODS: Two acquired clitoromegaly cases treated in Ataturk Training Hospital, Izmir, Turkey are presented. RESULTS: History from both patients revealed clitoromegaly over the last three years.

Combination of surgery and intralesional verapamil injection in the treatment of the keloid.

Keloid scars are one of the most challenging problems for physicians and surgeons. These scars have been treated in many ways, with varying success. Verapamil is a widely used calcium channel antagonist, and it has been shown that calcium channel blockers inhibit the synthesis/secretion of extracellular matrix molecules, including collagen, glycosaminoglycans, and fibronectin, and increase collagenase.

Cervicopectoral flap in head and neck cancer surgery.

BACKGROUND: Reconstruction of the head and neck after adequate resection of primary tumor and neck dissection is a challenge. It should be performed at one sitting in advanced tumors. Defects caused by the resection should be closed with flaps which match in color, texture and hair bearing characteristics with the face.

The creation of new rotation arc to the rat latissimus dorsi musculo-cutaneous flap with delay procedures.

Background: Latissimus dorsi musculocutaneous flap is one of the most frequently performed reconstructive techniques in surgery. Latissimus dorsi muscle has two arcs of rotation. It is classified as type V muscle.

Enhancement of Tissue Expansion by Calcium Channel Blocker: A preliminary study.

BACKGROUND: Reconstruction of the defects after surgical resection of tumors is one of the important issues in surgical oncology. It is essential that the defect should be covered with a tissue quite similar to the original one and is best achieved by harvesting tissue from an area adjacent to the defect. Tissue expansion is one of the most frequently used reconstructive techniques.

Primary malignant melanoma of the maxillary gingiva.

Background: Mucosal malignant melanoma arising from the mucosa of the head and neck region is a rare entity, accounting for approximately 0.2% of all melanomas. Most of these lesions (80%) have occurred on the maxillary anterior gingival area, especially on the palatal and alveolar mucosa.
