Variable Adjustment Methods for Hemihamate Autograft Arthroplasty in Proximal Interphalangeal Joint Fracture/Dislocations: A Surgical Technique Revisited and Case Series.

ABSTRACT: Proximal interphalangeal joint fracture/dislocations, even after surgical correction, often lead to long-term complications including posttraumatic arthritis, prolonged joint stiffness, and chronic joint instability. A wide range of surgical techniques has been devised to resolve this issue, but none has been promising enough. Despite this circumstance, arthroplasty using a hemihamate autograft of size and contour that match the middle phalangeal base has progressed into one of more acceptable methods that provide both articular congruency and osseous stability. In this article, we introduce various types of proximal interphalangeal joint fracture/dislocations and individualized surgical approach using hemihamate autograft and lag screw and/or hook plate as fixation methods.

Chronic Intratendinous Tophaceous Gout in Repaired Second Extensor Digitorum Communis and Extensor Indicis Proprius Tendons: A Case Report.

ABSTRACT: A 26-year-old male patient visited outpatient clinic for pain and palpable mass at 2nd extensor digitorum communis zone V region since last year. He underwent a posttraumatic extensor tenorrhaphy on the same location 11 years ago. Otherwise previously healthy, his blood test revealed an elevated uric acid level. Preoperative magnetic resonance imaging scan suggested a lesion, such as tenosynovial hemangioma and neurogenic tumor. Excisional biopsy was performed, and total excision of the compromised second extensor digitorum communis and extensor indicis proprius tendons was also necessary. Palmaris longus tendon was grafted to the defect. Postoperative biopsy report confirmed a crystalloid material with giant cell associated granulomas, suggestive of gouty tophi.

A Revision Mandibuloplasty: Causes, Indications, Surgical Methods and Treatment Outcomes.

BACKGROUND: This paper aims to propose a classification system to categorize patients undergoing revision mandibuloplasty according to their dissatisfaction types. This paper also introduces various appropriate revision techniques and evaluates their outcomes. Through this classification system and suggested surgical techniques, surgeons can settle the disappointments experienced by patients after their primary mandibuloplasty, by realizing more natural-looking results. METHODS: The study subjects consisted of 184 patients who underwent a revision mandibuloplasty from October 2010 to March 2016, conducted by a single surgeon at a single institution. The authors were able to classify the dissatisfaction into two primary types-(1) lack of an overall slender frontal facial contour and (2) unnatural and asymmetrical overall facial appearance due to over- or inaccurate resection of the bone. A self-evaluation of patient's subjective satisfaction based on the scale from 1 to 5, both after the primary operation and after revision surgery, was compared. RESULTS: Dissatisfaction type I accounted for 145 patients (78.8 percent). The number of patients classified into dissatisfaction type II was 39 (21.2 percent). Of the patients categorized into type I, those undergoing revision surgeries due to an under-corrected mandibular tubercle and parasymphysis showed the most remarkable improvement in self-satisfaction score after reoperation-from 2.3 to 4.0. CONCLUSION: To realize a natural-looking outcome in facial look through mandibular contouring, it is important not only to carefully consider the ratio and shape essential for an optimal slender facial contour, but also to minimize unnecessary resection of the bone.

Donor-site morbidities in 615 patients after breast reconstruction using a free muscle-sparing type I transverse rectus abdominis myocutaneous flap: a single surgeon experience.

Transverse rectus abdominis myocutaneous flap is one of the most commonly used reconstruction tools after oncological mastectomy. However, post-operative donor-site morbidities remain an issue to be addressed. In this study, we retrospectively reviewed patients with either immediate or delayed breast reconstruction using a free muscle-sparing type I transverse rectus abdominis myocutaneous flap only, performed by a single surgeon, regarding the donor-site morbidity. From January 2012 to July 2017, the study subjects summed up to 615 patients, in a single institution. Preoperative planning and actual surgical techniques were outlined including the evaluation of the location of the perforators using a three-dimensional abdominal computed tomography angiography scan, minimal fascia sacrifice, beveled dissection and minimization of the tension on the central abdomen during closure. During a 1-year follow-up, a total of 33 patients (5.4%) were complicated with any donor-site morbidity. Those in need of secondary revision on their donor-sites accounted for 23 patients (69.7%). No factor was found statistically significant to increase the risk of donor-site morbidity. Many surgical techniques have been devised for closure of the donor-site in transverse rectus abdominis myocutaneous flap patients. And, several factors have been proposed as increasing the risk of donor-site morbidity. Although all the suggested predictive factors failed to prove its significance on increasing the risk, a set of preoperative planning and surgical techniques employed in our study has proven to be both safe and efficient in lowering the postoperative donor-site morbidities.

Paraffinoma induced bilateral preauricular cheek skin defects.

"Paraffinoma" is a well-recognized complication of paraffin oil injection into various body parts for an aesthetic purpose. After a variable latency phase, paraffinoma can present as a wide range of clinical symptoms. This paper is a case report of surgical excision of the paraffinoma and subsequent reconstruction of the associated skin defect on bilateral preauricular cheeks, manifesting 50 years after a primary injection.

A Nipple-Areolar Complex Reconstruction in Implant-Based Breast Reconstruction Using a Local Flap and Full-Thickness Skin Graft.

INTRODUCTION: Nipple-areolar complex reconstruction is the final step of the reconstructive procedure in breast cancer patients. Nowadays, a combination of a local flap for nipple reconstruction and skin grafting or tattooing for areola reconstruction is deemed a first choice. In this paper, we are combining the techniques of local flap and full-thickness skin graft from the upper inner thigh for simultaneous reconstruction of the nipple and areola. PATIENTS AND METHODS: From January, 2016 to December, 2017, 23 female patients with an absent unilateral nipple-areolar complex due to post-oncological mastectomy and immediate implant-based breast reconstruction were subjects of the study. On an out-patient clinic basis, the percentage of the nipple projection loss was calculated at the intervals of 3 , 6 and 12 months postoperatively. At the final visit, the patient's subjective satisfaction on the reconstructed areola compared to the normal contralateral side was evaluated using a visual analogue scale. RESULTS: Over the course of time, the mean nipple projection loss was 20.16 ± 12.88, 31.78 ± 11.63 and 34.69 ± 12.01% at 3 , 6 and 12 months postoperatively, respectively. Patients' overall satisfaction on the grafted areola was as follows; the largest number of patients (8 patients) had a 'good' satisfaction 12-months postoperatively. Out of 21 patients, those who considered the result to be 'poor' and 'disappointing' each accounted for 1 and 3 patients. CONCLUSION: The combination of nipple-areolar complex reconstruction technique introduced in this study has proven to be a safe and efficacious alternative in patients with implant-based reconstruction requiring small- to medium-sized nipple projection, especially when the skin envelope is too tight for a local flap only.

Contouring of zygomatic soft tissue using bilateral free groin flaps in a Treacher Collins syndrome patient.

Treacher Collins syndrome is a congenital disorder that is characterized with a wide range of cranio-facial deformities. Zygomatic hypoplasia or aplasia is one of the key features, and surgical reconstruction of the consequent depression on the zygomatic area is deemed necessary by many patients. Various surgical options are available-injectables, alloplastic materials, autologous grafting, and autogenous tissue transfer. It depends on each patient which technique to use. Here, we present a clinical case, in which bilateral free groin flaps were adopted in attempt to resolve the remnant aesthetic deformity associated with zygomatic depression, despite a series of previous surgical efforts, in a 25-year-old Treacher Collins syndrome male patient.
