Dealing with the venous congestion of free flaps: venous catheterization.

For head and neck reconstruction after tumor ablation surgery, free flaps are mostly the chosen treatment modality for most of the centers. Coping with venous insufficiency and increasing venous outflow of the flap during this process increases the success rate. To increase venous outflow, triple-lumen central venous catheter is inserted to one of the donor veins of the flap that has venous insufficiency and one intact vein anastomosis.

Nasal hair matrix cyst mimicking dermoid cyst.

Dermoid cysts are primarily observed in the head and neck region. Nasal dermoids are uncommon. The terms nasal dermoid, nasal epidermoid, and nasal sebaceous cysts are used interchangeably by clinicians.

Pulley reconstruction with different materials: experimental study.

The digital fibroosseous pulley system is essential for optimum function of the flexor tendons and the continuation of normal hand functions. Different materials have been used for pulley reconstruction in the literature but the ideal material is still controversial. In this study, after the excision of the A2 pulley, pulley reconstructions were performed by using acellular dermal matrix, solvent dehydrated bovine pericardium, fascia lata, and free tendon graft in the rabbit model.

"Lid technique": cyanoacrylate-assisted anastomosis of small-sized vessels.

This paper presents the details of an experimental study of arterial anastomosis, combining suture with the cyanoacrylate tissue adhesive. At the distal end of the vessel, two parallel incisions were made, 180 degrees apart from each other, and two sutures were placed passing from the proximal end to exit from the most distal part of the longitudinal incisions. The tissue adhesive was then applied to the proximal vessel, and the full-thickness vascular 'lid' flap was closed over it on anterior and posterior surfaces.

Pinocchio nasal deformity secondary to lymphangioma circumscriptum.

Pinocchio or Cyrano nasal tip deformity is a rare situation that develops secondary to the soft tissue tumors underneath. In literature, there is only one case reported with Pinocchio nasal deformity secondary to cavernous lymphangioma. In this study, we present a Pinocchio or Cyrano nasal deformity with skin involvement secondary to lymphangioma circumscriptum.

Maxillary sinus lipoma: an unanticipated diagnosis.

Subcutaneous tissue gives rise to numerous lesions such as lipoma, the most common benign soft tissue tumors. Lipoma is seen only extremely rarely in osseous units. In addition, craniofacial involvement of intraosseous lipoma may be misdiagnosed as a fibroosseous tumour such as fibrous dysplasia.
