Purpose: Blepharoplasty plays a vital role in facial rejuvenation. Aging eyelids are the result of relaxation of lid structures as the skin, the orbicularis muscle, and mainly the septum, with subsequent protrusion or pseudoherniation of intraorbital fat contents. Traditional blepharoplasty has often involved the excision of excessive lax skin and muscle and removal of fat, leaving the eyelid unnatural and even causing the brow ptosis. The authors propose the septal approach through which the amount of skin excision can be decreased and solid fixation can be achieved in the upper blepharoplasty. Methods: From November 2007 to February 2010, total of 15 patients underwent upper blepharoplasty with septal approach. In 9 patients, orbital septum anchored into the orbital periosteum only. But in 6 patients, the attenuated septum was strengthened through shortening and fixing into orbital periosteum with non-absorbable suture. Results: Pleasing results were obtained from most of the patients. But one patient who had septum anchoring procedure complained of slight undercorrection, therefore secondary operation with septum shortening procedure was followed. Conclusion: We found that the method using orbital septum fixation into orbital periosteum has several advantages: less amount of skin excision, less recurrence rate, and more natural appearance. And the results were reliable and satisfactory.

We compared wound healing with $CO_2$ laser incision and scalpel incision by measuring the extent of bleeding, the ease of incision, time, degrees of adhesion and histological observation in pig's stomach. Eight healthy pigs were used. Two symmetrical incisions were made in ventral aspect of the stomach between the greater curvature and lesser curvature were made with scalpel and 2 mm spot diameter $CO_2$ laser (8W, continuous wave) in eight pigs. And then each wound was closed with absorbable suture in a two-layer inverting seromuscular pattern. At 7 and 14 days after initial wounding, each wound was taken for histological observation. On surgery, the extent of bleeding, the ease of incision and incision time showed significant differences between the two groups. The $CO_2$ laser provided better hemostasis (p < 0.01) and smaller postoperative adhesion compared with the scalpel. However, the scalpel produced faster speed of incision and was easier to handle than the $CO_2$ laser group (p < 0.01). There was no considerable difference between the two groups in histological observation.

The objective of the present study was to evaluate the effectiveness of autoligation techniques for castrating healthy male small breed dogs. Forty dogs were divided into four groups, with 10 in each group, based on maturity and the surgical technique used: 1) immature dogs aged less than 1 year, with autoligation of the spermatic cord via a scrotal approach (SAL) as the surgical technique (SAL-IM); 2) mature dogs aged 1 year or older, with the same SAL surgical technique (SAL-M); 3) immature dogs aged less than 1 year, with double ligation of the spermatic cord with an absorbable suture via a prescrotal approach (PDL) as the surgical technique (PDL-IM); and 4) mature dogs aged 1 year or older, with the same PDL surgical technique (PDL-M). The effectiveness of the surgical technique was evaluated by comparing the operating time and complications between these four groups. The significant decreases in operating times were found in SAL-IM and SAL-M compared with those of PDL-IM and PDL-M (p < 0.01 and p < 0.01). Regardless of maturity, the SAL surgical technique reduced operating time by approximately 69.5% compared with the PDL surgical technique. When the complication severities were scored, the results showed no significant differences among the four group. The autoligation technique for castration in healthy male small breed dogs is considered to be effective because the operating time consuming is less than conventional techniques.

Zygomaticomaxillary complex (ZMC) fractures account for a substantial proportion of trauma cases. The most frequent complications of maxillofacial fracture treatment are infections and soft tissue flap dehiscence. Postoperative infections nearly always resolve in response to oral antibiotics and local wound care. However, a significant infection can cause a permanent fistula. A 52-year-old man visited our clinic to treat an oroantral fistula (OAF), which was a late complication of a ZMC fracture. Postoperatively, the oral suture site dehisced, exposing the absorbable plate. However, he did not seek treatment. After 5 years, an OAF formed with a $2.0{\times}2.0cm$ bony defect on the left maxilla. We completely excised the OAF, harvested a piece of corticocancellous bone from the iliac crest, inserted the harvested bone into the defect, and covered the soft tissue defect with a buccal mucosal transposition flap. Although it is necessary to excise OAFs, the failure rate is higher for large OAFs (> 5 mm in diameter) because of the extensive defect in the underlying bone that supports the overlying flap. Inappropriate management of postoperative wounds after a ZMC fracture can lead to disastrous outcomes, as in this case. Therefore, proper postoperative treatment and follow-up are essential.

Background Bioabsorbable plates and screws are commonly used to reduce maxillofacial bones, particularly in pediatric patients because they degrade completely without complications after bone healing. In this study, we encountered eight cases of a delayed foreign body reaction after surgical fixation with bioabsorbable plates and screws. Methods A total of 234 patients with a maxillofacial fracture underwent surgical treatment from March 2006 to October 2013, in which rigid fixation was achieved with the Inion CPS (Inion, Tampere, Finland) plating system in 173 patients and Rapidsorb (Synthes, West Chester, PA, USA) in 61 patients. Their mean age was 35.2 years (range, 15-84 years). Most patients were stabilized with two- or three-point fixation at the frontozygomatic suture, infraorbital rim, and anterior wall of the maxilla. Results Complications occurred in eight (3.4%) of 234 patients, including palpable, fixed masses in six patients and focal swelling in two patients. The period from surgical fixation to the onset of symptoms was 9-23 months. Six patients with a mass underwent secondary surgery for mass removal. The masses contained fibrous tissue with a yellow, grainy, cloudy fluid and remnants of an incompletely degraded bioabsorbable plate and screws. Their histological findings demonstrated a foreign body reaction. Conclusions Inadequate degradation of bioabsorbable plates caused a delayed inflammatory foreign body reaction requiring secondary surgery. Therefore, it is prudent to consider the possibility of delayed complications when using bioabsorbable plates and surgeons must conduct longer and closer follow-up observations.

Purpose: Microfat graft is a common procedure for correcting tear trough deformity and dark circle. Because the tissue in this area is very thin, the grafted fat, sometimes, induces palpable lumps and uneven skin contour. When it happens, the surgical removal of the grafted fat is often needed. The authors made attempt of transconjunctival approach for removal, and this made infraorbital fat repositioning possible at the same time. Methods: 15 female patients with history of microfat graft on lower eyelid, got operation for the grafted fat removal with transconjunctival approach from April of 2009 to July of 2010. The dissection was performed in accordance with infraorbital fat repositioning surgery. Through the transconjunctival incision, knotted fat on orbital septum and orbicularis oculi muscle was removed without damage on skin. After grafted fat removal, subperiosteal space was made 1~2 mm below the inferior orbital rim by elevating periosteum. With preserving orbital septum, infraorbital fat was repositioned and anchored to subperiosteal space. Finally, transconjunctival incision was closed with absorbable suture material. Results: 14 patients in the study showed satisfactory results. The problems like uneven skin contour and knotted fat mass, were all solved. In only one patient, incomplete correction was observed, as bulging on her right lower eyelid still remained. One patient complained of transient numbness on lower eyelid, but there was no specific complication other than this. Conclusion: The authors attempted the method of transconjunctival approach to remove former grafted fat in lower eyelid and reposition infraorbital fat simultaneously. Since the study brought great results, the method would be helpful to patients and surgeons.

Background Intractable chronic scalp ulcers with cranial bone exposure can occur along the incision after cranioplasty, posing challenges for clinicians. They occur as a result of severe scarring, poor blood circulation of the scalp, and focal osteomyelitis. We successfully repaired these scalp ulcers using a vascularized bipedicled pericranial flap after complete debridement. Methods Six patients who underwent cranioplasty had chronic ulcers where the cranial bone, with or without the metal plate, was exposed along the incision line. After completely excising the ulcer and the adjacent scar tissue, subgaleal dissection was performed. We removed the osteomyelitic calvarial bone, the exposed metal plate, and granulation tissue. A bipedicled pericranial flap was elevated to cover the defect between the bone graft or prosthesis and the normal cranial bone. It was transposed to the defect site and fixed using an absorbable suture. Scalp flaps were bilaterally advanced after relaxation incisions on the galea, and were closed without tension. Results All the surgical wounds were completely healed with an improved aesthetic outcome, and there were no notable complications during a mean follow-up period of seven months. Conclusions A bipedicled pericranial flap is vascularized, prompting wound healing without donor site morbidity. This may be an effective modality for treating chronic scalp ulcer accompanied by the exposure of the cranial bone after cranioplasty.
