Utilization of images and three-dimensional custom-made nostril retainer fabricate for patients with cleft lip and cleft lip nose deformities at Siriraj Hospital: preliminary phase.

A prospective study utilizing image analysis to assess nostril openings in post-operative patients with cleft lip and cleft lip nose deformities. This preliminary study seeks to employ two-dimensional (2D) images to fabricate a custom-made nostril retainer. This study was performed at Faculty of Medicine, Siriraj Hospital, Mahidol University, Thailand.

Anatomy of medial plantar superficial branch artery perforators: Facilitation of medial plantar superficial branch artery perforator (MPAP) flap harvesting and design for finger pulp reconstruction.

Background: Medial plantar artery perforator (MPAP) flap was proposed as proper option for finger pulp reconstruction. To provide the previously unavailable vessel information required for this small flap design, this study aimed to gather all necessary anatomy of MPA, MPAP, and their territories of blood supply to apply in clinical MPAP flap reconstruction minimizing perforator injury.

Methods: Dissection of 30 Thai cadaveric feet for visualizing superficial branch of MPA and its perforators (MPAP) using acrylic dye cannulation were performed.

Vascular Nature and Existence of Anastomoses of Extrinsic Postauricular Fascia: Application for Staged Auricular Reconstruction.

A staged auricular reconstruction in microtia patients was developed by using superficial mastoid fascia (as part of extrinsic postauricular fascia) to cover the cartilagenous framework due to its highly vascularized nature. Three branches of external carotid artery (superficial temporal artery, posterior auricular artery and occipital artery) were found to supply this fascia, this study was therefore aimed to investigate the dimension of blood supply from each vessel and also to demonstrate the existence of anastomoses among these arteries. Thirty-eight pinnas and postauricular fascias from Thai fresh adult cadavers were included to document the anastomoses by showing both perfused dye connection (10 dissections) and visible anastomotic branches (8 dissections) among them.

Purse-string closure for frontoethmoidal encephalomeningocele.

Background: Skin incision over the nose is routinely made for accessing the nasal structures, removing the mass, as well as resecting the redundant skin in patients with frontoethmoidal encephalomeningocele (FEEM). Unfortunately, the conventional elliptical excision leaves a long, straight-line scar that becomes a stigma of the disease.

Objective: The author describes a purse-string closure technique for closure of the skin defect over the nasal dorsum in a patient with FEEM, which results in the reduction of a surgical scar.

The cellular plasticity of human adipocytes.

Little is known regarding the biology of fat considering its extensive use clinically in soft tissue implantation. Free-fat transfer is problematic the result of graft site volume loss, appearing histologically as the replacement of mature adipocytes with a fibroblast-like infiltrate. We hypothesize that these histologic changes reflect a dedifferentiation of ischemic mature adipocytes instead of, or in addition to, a more traditional response.

Embolization of vascular malformations in head and neck regions. A single center experience.

The purpose of this study is to determine the effectiveness of embolization of each type of vascular malformation. Thirty three patients with a diagnosis of vascular malformations in head and neck regions who were treated by embolization at Siriraj Hospital, Thailand, between 1997-2002 were reviewed retrospectively. There were 19 arteriovenous malformations (AVMs), two arteriolar-capillary types, ten venous malformations, one veno-lymphatic malformation and one mixed capillary and venous types.

Shortening of mandibular linear distance with multivector distraction.

It was noted that when a multivector distractor is used, there is shortening of the linear distraction distance when the gonial angle is reduced and the transverse distance is increased. The purpose of this study was to measure the distance change at the mandibular corticotomy site when the gonial angle is reduced or the transverse distance is increased. The Synthes multivector distractor was used in this experiment.

Epidemiology of cleft lip and palate in Thailand.

During the years 1989 to 1991, a survey for the epidemiology of cleft lip and palate was carried out in Thailand using detailed forms. One thousand ninety-six patients were recorded and 593 patients were operated during that period. All records were analyzed.
