Refinements in Gender-Affirming Feminizing Chest Surgery

Background Feminizing top surgery, or mammaplasty augmentation, has multiple variables that surgeons can adjust to work synergistically with patient anatomy including plane of implant placement, pocket size, and inframammary fold (IMF) location. In the gender diverse population receiving this procedure to reduce symptoms of gender dysphoria, surgeons should be aware of differing anatomy and surgical approaches for feminizing top surgery. Methods A retrospective chart review was conducted using our institution's electronic health record between December 2019 and May 2023 with a minimum follow up period of 12 months. Inclusion criteria included transgender women, nonbinary patients, and all patients who did not identify as cis-gender women and who underwent feminizing top surgery. Demographic data including age, race, ethnicity, and gender were collected. Complication rates were recorded for hematoma, infection, seroma, wound dehiscence, hypertrophic scar, minor contour abnormalities, implant asymmetry, and revision surgery. Results Our surgeons' subfascial approach, which uses 2 equations to calculate dissection pocket dimensions and determine placement of pocket and incision based on desired implant base diameter and projection, was performed on 140 gender-diverse patients and resulted in a hematoma rate of 4.29%, an infection rate of 2.86%, and a seroma rate of 1.42% with good cosmetic outcomes, as evidenced by our low rates of minor contour abnormalities (5.71%) and implant asymmetry (1.43%). Only 5 patients (3.57%) required revision surgery. Conclusions Bilateral breast augmentation with round implants in a subfascial plane using a concealed IMF incision following equations to determine the dissection pocket size and new IMF position and incision position is a reproducible technique that results in good aesthetic outcomes and minimizes complications.

Artificial Intelligence, Genuine Outcome: Analysis of 72 Consecutive Cases of Subfascial Augmentation Mastopexy With Smooth Round Implants Supported by P4HB Scaffold.

Ptosis recurrence often leads to unsatisfactory results after mastopexy, even more so when additional stress is provided by implants on compromised native tissue. The poly-4-hydroxybutyrate(P4HB) scaffold (GalaFLEX) with its favorable safety profile and proven long-term mechanical strength represents a preferred option for soft tissue support. The primary endpoint was assessment of lower pole stretch from the early postoperative period up to 3 years. Out of 151 patients who underwent surgery by G.B. from March 2020 to December 2023, a total of 72 with a 12-month-mininum follow-up who had primary (46) or secondary (26) augmentation mastopexy with subfascial round smooth implants and P4HB scaffold support were included in the study. Three-dimensional artificial intelligence software was utilized for all measurements. Further analysis included evaluation of ptosis recurrence and all complications. No recurrent ptosis, bottoming out, implant displacement, or capsular contracture was reported during follow-up (mean, 24.8 months). The lower pole arch's elongation was 8.04% and 9.44% at 1 and 3 years respectively, comparing favorably with previous reports. Statistically significant correlation (P < .05) between implant size and lower pole stretch was noted, this being greater for larger implants (> 400 cc; P = .0011) and primary cases (P = .1376). Progressive volume redistribution from upper to lower pole was observed in the first year, with substantial stability thereafter. This is the largest published series reporting long-term results (up to 45 months) in mastopexy augmentation with GalaFLEX, suggesting its supportive role in lower pole stability even in the setting of concurrent breast augmentation with smooth implants in a subfascial plane.

Outcomes in Subfascial versus Subglandular Planes in Breast Augmentation: A Systematic Review and Meta-Analysis.

Breast augmentation is the most commonly performed aesthetic surgery procedure in women worldwide. The use of the subfascial plane has been suggested to decrease the incidence of capsular contracture compared to the subglandular plane, while simultaneously avoiding the complication of animation deformity in the subpectoral plane. The aim of this systematic review and meta-analysis was to compare the adverse outcomes of subfascial compared to subglandular planes in breast augmentation. This review was registered a priori on OSF (https://osf.io/pm92e/). A search from inception to June 2023 was performed on Medline, Embase, and CENTRAL. A hand search was also performed. All randomized and comparative cohort studies were included that assessed the use of the subfascial plane for breast augmentation. Outcomes evaluated included the incidences of seroma, hematoma, infection, rippling, capsular contracture, and revision surgery. Ten studies were included in this systematic review. Three randomized controlled trials and seven comparative cohort studies were used for quantitative synthesis. There was a significant difference favoring subfascial compared to subglandular planes in the incidence of hematoma, rippling, and capsular contracture. All included studies had high risk of bias. The current evidence suggests that the subfascial plane for breast augmentation decreases risk of capsular contracture, hematoma, and rippling compared to the subglandular plane. Further randomized evidence with high methodological rigor is still required to validate these findings.

Endoscopic Transaxillary Breast Augmentation – a Case Series of 1300 Patients

Abstract Level of Evidence: V – case series Goals/Purpose Breast augmentation is currently one of the most common aesthetic surgical procedures performed in the United States. Transaxillary breast augmentation offers an advantageous hidden scar compared with other options for implant placement. While first described as a blunt and blind approach, endoscopic technique further refined this procedure to offer surgeons complete control and visualization of dissection for precise implant placement. Despite this, breast augmentation is done far more commonly as was initially described over 60 years ago with incisions on the breast that can result in visible scarring. The purpose of this study was to report surgical outcomes on the largest published series to date in a patient cohort of 1389 endoscopic transaxillary breast augmentations. We describe the refinement of this technique and statistical analysis of patient outcomes. Methods/Technique This study included all patients with breast hypoplasia who chose endoscopic transaxillary breast augmentation from 2006 to 2022 by a single surgeon (S.C.). All patients were followed for a minimum of 3 months post procedure. All implants used were smooth, round, silicone gel implants with volumes ranging from 180 to 800cc. Implants were placed in the subfascial or submuscular plane. An incision was marked in the most prominent axillary crease. If there were no creases, an incision was marked at the highest point of the armpit along Langer’s lines. A 30 degree endoscope (Karl Storz, USA) was placed in an endoscopic breast retractor (Karl Storz, USA) and dissection proceeded either in the submuscular plane between the pectoralis major and minor, or in the subfascial plane with an angled suction cautery (Black and Black Surgical, Texas). In the case of subfascial implant placement, the pocket was dissected according to the preoperative markings. With submuscular placement, pocket dissection also followed markings, but the pectoralis muscle was divided with cautery from the level of the areola along the sternal origins of the muscle to completely divide the muscle inferiorly and laterally. The inframammary fold was lowered as necessary by cautery dissection above the level of the pectoralis fascia inferiorly. Glandular scoring was performed with cautery when needed as well. After dissection was completed, saline breast implant sizers were inserted and filled with air to estimate implant size and confirm pocket dissection in the upright position. Adjustments were made to the implant pocket with endoscopic cautery dissection as was necessary. Results/Complications A total of 1389 patients were included in our data analysis for surgeries performed between March 2006 and December 2021. Overall complication rate in our cohort was 6.69%. Malposition of implants was the most common complication at 3.64%. Contracture rate was 1.74%. There was a significant increase noted in hematoma rate in subfascial placement (3.51% increase, p-value&amp;lt;0.05) compared to submuscular and a decrease in implant malposition in the subfascial group (6.58% decrease, p-value&amp;lt;0.05) compared to the submuscular group. These complications were largely managed using endoscopic techniques. There were no significant differences noted between subfascial, subglandular and submuscular pocket placement in asymmetry, contracture and hypertrophy. Conclusion We describe a safe and effective approach to endoscopic transaxillary breast augmentation that has demonstrated long term results compared to the direct vision inframammary technique. The advantages of a hidden scar should be a consideration for surgeons to adopt this technique to improve patient outcomes.

Pre-expanded thin DIEP free flap in pediatric upper extremity reconstruction for burn sequelae: A case report

Deep burns sequelae involving the upper limb are challenging even for experienced surgeons, mainly because local reconstructive options and donor sites are often compromised. The use of free flaps for this type of reconstruction remains difficult due to the small recipient vessel diameter and tendency to vasospasm. Moreover, pediatric cases bring the challenge to another level. We present the case of a 13-year-old girl presenting major retractile sequelae of the upper left limb, including complete wrist immobilization combining wrist hyper-extension, ulnar deviation deformity, and a ulno-carpal dislocation. She was referred to our department where a two-stage reconstruction was performed using a pre-expanded free deep inferior epigastric artery perforator (DIEP) flap. The first surgery consisted of placing two kidney-shaped expanders in a subfascial plane in the hypogastric region. Four months later, after a bi-weekly expansion, an excision of the scar tissue, and the DIEP flap transfer were completed. At the 12-month follow-up evaluation, both aesthetic and functional results were satisfactory, with a good contour and regained mobility of the wrist.

Subfascial Mini Muscle-Release Dual Plane Technique: A Modified Procedure for Breast Augmentation.

Each breast augmentation technique has advantages and indications, and the quest for the perfect implant pocket plane is ongoing. An ideal dual plane should meet three requirements: adequate implant coverage, optimal control of breast shape, and maximal muscle preservation. This paper reports a modified procedure for breast augmentation named subfascial mini muscle-release dual plane technique. From an inframammary or periareolar approach, the implant pocket is dissected in a subfascial plane up to the pectoralis major. The muscle is split 3 cm above the lateral margin and then pocket dissection proceeds in the submuscular plane. A small portion of the costal origin is divided inferomedially creating a dual plane. A total of 178 patients with hypoplasia or breast atrophy were included, among whom 34 had breast ptosis and 20 had tubular breast deformity. The median follow-up period was 20 months. With an average implant volume of 268.8 ml and a smooth implant type of 85.4%, there was 1 case of hematoma, 2 cases of wound healing issues, 2 cases of rippling sign, 2 cases of grade III/IV capsular contracture, 5 cases of implant malposition and 12 cases of mild muscle contraction-associated deformity. Revision surgeries were performed on 2 patients. The subfascial mini muscle-release dual plane technique is an easy method for breast augmentation and is especially indicated for ptotic breasts and tubular breast deformities. This technique combines the advantages of traditional dual plane and muscle-splitting techniques, yielding a satisfactory aesthetic outcome.

Supraclavicular Artery Perforator Based Flap in Reconstruction of Neck Soft Tissue Defects: Our Experience.

Neck reconstruction is challenging task as it requires achievement of both function and aesthetic form as it is exposed and visible part of body. Various reconstruction modalities like Skin graft to free flap has been described in literature (Achauer and Sood's Burns Surgery, edition 2006). We used Supraclavicular artery perforator based island Flap for resurfacing defect in Five patients. After localization of Supraclavicular artery perforator with hand held Doppler; flap was raised in subfascial plane and inset was given under anesthesia. Out of five patients, there were two males and three females. Three patients had Postburn neck contractures, one had post electrical burn defect, and one had post infective defect over neck region. All flaps survived well without any complications. Supraclavicular artery perforator based island Flap is a reliable soft tissue cover for neck defects from various etiologies.

Dacryocystectomy: A fibrin glue-assisted subfascial excision.

This article describes a technique of dacryocystectomy involving dissection within the subfascial plane, in which the lacrimal sac fascia is preserved and the orbital fat remains undisturbed. The lacrimal sac cavity was directly injected with Tisseel fibrin glue mixed with trypan blue. This led to sac distension and facilitated its separation from surrounding periosteal and fascial attachments. Staining the lacrimal sac epithelium improved definition of the mucosal lining. Transverse sections of the lacrimal sac specimen were histologically analyzed, which confirmed that dissection was completed within a subfascial plane. The technique herein described facilitates en bloc excision of the lacrimal sac without breaching the fascial plane that separates the sac from orbital fat.

Reduction of the scar burden at the donor area of the radial forearm flap with the aid of an endoscopic pedicle preparation.

The radial forearm flap is one of the most commonly used flaps of reconstructive microsurgery with its long pedicle and thin structure. The donor site at the forearm is a visible anatomic region that has high mobility and functional importance. In this study, a longitudinal and large scar was avoided on the forearm during pedicle dissection of the conventional radial forearm flap with the utilization of an endoscope. Furthermore, arterial, venous, and nervous injuries were avoided by performing a separate inci-sion of 2-3 cm at the cubital fossa to reduce flap failure and donor site morbidity. The patients who underwent pedicle dissection of the radial forearm flap with the aid of an endoscope for head-neck reconstruction between 2014 and 2021 were included in this study. The flap was harvested from the subfascial plane. The cephalic vein was used in all of the patients. When the pedicle dissection reached the antecubital region, an incision of 2-3 cm was performed from the skin. Two vein anastomoses were performed for each patient. This retrospective study consists of 51 patients. While 45 of the patients were the result of head and neck cancer, six of them had a defect caused by trauma. The average area of skin islands was 40.3 cm2, while the full-thickness skin graft size was 24.2 cm2. An average of 2.6 cm of scar tissue was formed at the antecubital region. No venous or arterial compromise was observed in the post-operative period. There was no partial or total flap loss in any patient. Localized numbness persisted in the skin area where the superficial sensory branch of the radial nerve is located in 6 (11.7%) patients. With endoscopic radial forearm flap harvesting, the longitudinal incision in the forearm and wound healing prob-lems are avoided. The absence of partial or total flap loss has shown that endoscopic harvesting of the radial forearm flap is a safe and reliable method.

Treatment of chest wall osteoradionecrosis with a contralateral breast Y-V flap: a case report

Chest wall osteoradionecrosis, one of the most serious complications of radiation therapy for breast cancer treatment, is usually treated by wide debridement followed by coverage with a well-vascularized flap. However, the extent of radiation-induced injury and limits in performing wide resection of the injured bones often present challenges in treatment. Herein, we present our experience treating chest wall osteoradionecrosis with a contralateral breast Y-V flap in an 81-year-old woman. She was diagnosed with chest wall osteoradionecrosis and had grade 3 ptotic breasts. Redundant contralateral breast tissue was used for reconstruction to cover the wound. The flap was elevated in the subfascial plane after an inverted-T incision was made in the lower pole and inframammary fold of the contralateral breast, while preserving the perforators of the left lateral thoracic artery. The flap was spread using the Y-V advancement fashion to cover the wound. The patient was discharged 2 weeks after surgery. At 19 months postoperation, there were no complications or recurrence. The patient was satisfied with the short recovery time and surgical results. The contralateral breast Y-V flap allows simple and quick reconstruction, potentially expanding the available treatment options and therefore increasing flexibility in choosing a treatment plan for patients.

Vessel loop tourniquet for penis dermatologic surgery

A 55-year-old man presented to our dermatology department with a squamous cell carcinoma of the foreskin (Fig 1). The planned treatment consisted of an extended circumcision using the sleeve technique.1 Regional block anesthesia was performed by infiltrating the dorsal nerves of the penis with 2% mepivacaine in the subfascial plane. The penis is a highly vascularized organ and the use of vasoconstrictors such as epinephrine is not recommended during penile regional block. How could bleeding during penis dermatologic surgery be minimized?

Smooth versus Textured Implants and Their Association with the Frequency of Capsular Contracture in Primary Breast Augmentation.

Capsular contracture is the most frequent complication of breast implant augmentation. Although studies indicate that textured implants have a low incidence of contracture, they have been associated with anaplastic cell lymphoma, which influences the choice of surface. This study estimated and compared the annual capsular contracture rate of both smooth and textured implants in primary breast implants. Two hundred fifty-three patients (506 implants) were evaluated from January of 2017 to July of 2019; 42.2 percent of the implants were smooth and 57.8 percent were textured. The inframammary approach was used in the subfascial (55.3 percent) and submuscular (44.7 percent) pockets. The primary outcome was the appearance of capsular contracture (Baker grade II, III, and IV) within the first postoperative year. Smooth implants had a higher capsular contracture rate at 1 year postoperatively compared with textured implants, although with borderline statistical significance (p = 0.06). Smooth surface breast implants in the subfascial plane had a 4-fold higher risk of contracture than those with a textured surface in the same plane (OR, 4.4; 95 percent confidence interval, 1.6 to 12.4). However, when placed in the submuscular plane, both textures had a similar contracture risk. The rate of contracture was similar after 2 years postoperatively (p = 0.21). Using the inframammary approach and a standardized technique, there were no significant differences in the incidence of capsular contracture between the smooth and textured implants. In the subfascial plane, the contracture rate with smooth implants was higher than with textured implants. However, in the submuscular plane, there was no difference between the surfaces. Therapeutic, III.

Subfascial\u2010located contraceptive devices requiring surgical removal

BackgroundSubdermal etonogestrel implants are highly effective contraceptive methods. Despite standardization of insertion technique by the manufacturer, some implants are inadvertently placed too deeply within or below the plane of the biceps brachii fascia. Placement of these implants in a deep tissue plane results in more difficult removal, which is not always possible in the office setting. In rare cases, surgical removal by an upper extremity surgeon is warranted.Case presentationHere we present 6 cases of etonogestrel implants located in a subfascial plane requiring removal by an upper extremity surgeon. Implants were all localized with plain radiography and ultrasound prior to surgical removal. All cases had implants located in the subfascial plane and one was identified intramuscularly. The average age was 28 years (19–33) and BMI was 24.0 kg/m^2 (19.1–36.5), with the most common reason for removal being irregular bleeding. The majority of cases (5/6) were performed under monitored anesthesia care with local anesthetic and one case utilized regional anesthesia. All implants were surgically removed without complication.ConclusionsInsertion of etonogestrel contraceptive implants deep to the biceps brachii fascia is a rare, but dangerous complication. Removal of these implants is not always successful in the office setting and referral to an upper extremity surgeon is necessary to avoid damage to delicate neurovascular structures for safe removal.

Predictive risk factors for facial nerve injury in temporomandibular joint replacement surgery

The objective of this study was to determine the prevalence of temporary and permanent facial nerve injury in total temporomandibular joint (TMJ) replacement surgery and to identify potential predictive risk factors. We made a retrospective review of case notes and opportunistic review of patients treated in a single tertiary referral unit by a single surgeon. For each patient a number of potential risk factors were determined, and the presence or absence of nerve injury recorded at 2 week follow up and a minimum of 12 months follow up. At 2-week review, facial nerve weakness was noted in 38/133 cases (28%) and at last follow up there were 4/133 cases (3%) with continuing (permanent) facial nerve weakness. Bilateral surgery, revision TMJ replacement, primary diagnosis, the number of previous surgeries and a history of recovered facial nerve injury all significantly increased the likelihood of temporary facial nerve injury, but not the likelihood of permanent facial nerve injury. Factors which increase the risk of temporary facial nerve injury are relatively predictable and include bilateral surgery, revision TMJ replacement, and multiple open TMJ surgeries. Risk factors associated with permanent injury are less predictable but are likely to be similar. The identification of such factors allows for the risk stratification of patients and improve informed consent. We also recommend that patients with a single, previously failed open TMJ surgery should be considered for early TMJ replacement and in multiply operated patients a subfascial plane of dissection is adopted.

Experience on Subfascial Mammary Augmentation and Influence of Incisions on Technique

Introduction: Mammary augmentation is among the most popular types of cosmetic procedures and mammary prosthesis the most commonly accepted technique. A mammary prosthesis can be placed on transaxillary, periareolar, submammary incisions in subglandular, subpectoral, subfascial planes or in a combination of planes. Given the potential interaction between the prosthesis and the surrounding tissues, the plane in which the prosthesis is implanted has an important role among the factors affecting this interaction. The plastic surgeon decides on the incision and plane to be used by assessing the advantages and disadvantages. Materials and Methods: Prostheses were implanted in the subfascial plane in 47 patients who underwent augmentation mammaplasty. Round Moderate Plus or High Profile Cohesive II™ Gel implants were used. Device volumes ranged from 275 to 600 cc. Of the 47 procedures, 23 were performed over an axillary incision, 20 over an inframammary incision, and 4 over a periareolar incision. Endoscopic-assisted dissection was performed in all of the 23 cases in which transaxillary incision was used. Results: All 47 patients who underwent subfascial prosthesis implantation were followed up for a mean of 5 years (range: 2–7 years). Long-term results were satisfactory with few complications. The overall patient satisfaction rate was 89.3%, and none of the patients required an implant removal or change. None of the patients complained of severe pain, regardless of the type of incision, and resumed their daily activities on postoperative day 2. Conclusion: The subfascial augmentation technique provides good and long-term results. It requires longer operating times and is a more difficult technique compared to other planes. As the choice of incision does not largely affect the overall result, the position of the scar depends on the patient's preference, the properties of the implant, and the experience of the surgeon. The endoscopic assistance should be preferred when using the transaxillary approach.

Use of the Subfascial Plane for Gender-affirming Breast Augmentation: A Case Series.

Background:Transgender women seeking gender-affirming breast augmentation often present with differences in preoperative chest measurements and contours in comparison with cisgender women. These include a more robust pectoralis muscle and limited glandular tissue, raising important considerations in determining the optimal anatomical plane for implantation. Abundant literature has described advantages and drawbacks of the available planes for breast augmentation in cisgender women. Certain drawbacks may be more pronounced for transgender women, given their distinct anatomy. The subfascial plane offers lower complication rates than the subglandular plane when using smooth implants, and avoids implant animation and displacement associated with the subpectoral plane. To our knowledge, existing studies have not yet addressed this discussion in the transfeminine population. The goal of this article is to highlight potential benefits of the subfascial plane for gender-affirming breast augmentation, utilizing a case series of 3 transfeminine patients, and to review the literature on surgical techniques and outcomes in this population.Methods:A retrospective chart review of patients presenting to a single surgeon for gender-affirming breast augmentation in 2019 was performed. A narrative literature review on surgical techniques and outcomes for gender-affirming breast augmentation was conducted.Results:Three cases of gender-affirming breast augmentation using subfascial implant placement are described. From the literature search, 12 articles inclusive of 802 transfeminine patients were identified.Conclusions:The subfascial plane represents an option for implant placement in gender-affirming breast augmentation that merits further investigation. There is a need for more research comparing surgical techniques and outcomes in the transfeminine population.

Bracka Urethroplasty with Buccal Mucosa Graft: Ergonomic Management of Penile Skin Dartos in the First Stage to Facilitate Second-stage Neourethral Coverage.

Aims:The aim of the study was to report a new technique of ergonomic penile skin-dartos management during buccal mucosa graft (BMG) to provide adequate penile skin-dartos for neourethral coverage at the time of second-stage tubularization.Materials and Methods:Ten proximal hypospadias with severe chordee underwent first-stage surgery with a new technique. An incision along the urethral plate margin and preputial edge was used to split inner prepuce off preputial dartos and penile degloving leaving inner prepuce attached to corona. Urethral plate was divided into the subfascial plane. Penile dartos was bisected in the dorsal midline. Distal half of penile skin-dartos bifurcated and joined to inner preputial edges. Mobilized and lateralized penile skin-dartos was sutured flanking edges of BMG. The second-stage tubularization after 6 months provided neourethral double dartos coverage with eccentric suture lines.Results:Adequate dartos for neourethral coverage during second-stage tubularization was available in all. Subcoronal urethrocutaneous fistula occurred in one that was repaired.Conclusions:Ergonomic management of inner-preputial skin and ventral transfer of penile skin-dartos helps in providing neourethral coverage during subsequent second-stage tubularization to minimize the occurrence of complications.

A Novel Abdominal Decompression Technique to Treat Compartment Syndrome After Burn Injury

BackgroundPrevalence of abdominal compartment syndrome (ACS) is estimated to be 4%-17% in severely burned patients. Although decompressive laparotomy can be lifesaving for ACS patients, severe complications are associated with this technique, especially in burn populations. This study outlines a new technique of releasing intraabdominal pressure without resorting to decompressive laparotomy. Materials and methodsTen fresh tissue cadavers were studied; none of whom had had prior abdominal surgery. Using Veress needles, abdomens were insufflated to 30 mm Hg and subsequently connected to arterial pressure transducers. Two techniques were then used to incise fascia. First, large skin flaps were raised from a midline incision (n = 5). Second, small 2 cm cutdowns at the proximal and distal extent of midaxillary, subcostal, and inguinal incisional sites were made, followed by tunneling a subfascial plane using an aortic clamp with fascial incisions made through the grooves of a tunneled vein stripper (n = 5). Pressures were recorded in the sequence of incisions mentioned previously. ResultsThe open midline flap technique decreased abdominal pressure from a mean pressure of 30 ± 1.8 mm Hg to 6.9 ± 5.0 mm Hg (P < 0.01). The minimally invasive technique decreased intraabdominal pressure from 30 ± 0.9 to 5.8 ± 5.2 mm Hg (P < 0.01). This technique significantly reduced intraabdominal pressure via extraperitoneal component separation and fascial release at the midaxillary, subxiphoid, and inguinal regions. ConclusionsThis technique offers the benefit of reducing the morbidity, mortality, and complications associated with an open abdomen, which may be beneficial in the burn injury population.

Vascularized Clavicular Bone With Supraclavicular Artery Island Flap for Oromandibular Reconstruction.

To explore the feasibility of an original surgical technique for head and neck oncologic reconstruction utilizing a pedicled osteocutaneous supraclavicular artery island flap (SCAIF) in a cadaver model. Cadaver dissection, Review of literature. Two fresh frozen cadavers, 1 male and 1 female, were used for the dissection. Prior to dissection, measurements were taken on length of clavicle and distance between clavicular articulations and mandibular landmarks with the head in a neutral position. The SCAIF flap was raised in a subfascial plane and a 4.0 cm partial thickness clavicular bone graft was harvested attached to the flap. The pedicle was identified and the length of the supraclavicular artery was noted. The skin paddle was tunneled into the floor of mouth and the bone was placed into a pre-cut 4.0 cm mandibular body defect and fixated with a 1.7 mm Stryker mandibular reconstruction plate. The male cadaver clavicle measured 16.4 cm in length. The distance from the sternoclavicular joint (SC) to the angle and symphysis of the mandible was 15.3 cm and 15.0 cm, respectively. In this cadaver, the bony graft and the vascular pedicle was not of sufficient length to reach the mandibular defect after tracing the vascular pedicle to the thyrocervical trunk (TCT), which was 13.3 cm from the mandibular angle (MA). The female cadaver had an average clavicular length of 15.0 cm, SC to angle 10.5 cm and SC to symphysis 8.1 cm. The bony graft and the vascular pedicled effortlessly reached without tension, with TCT only 7.8 cm from the MA and allowed sufficient bone graft mobility for plating. In this cadaveric model, a novel approach utilizing an osteocutaneous SCAIF was shown as a feasible reconstruction option for oromandibular defects in selected patients. This technique is limited by the anatomical relationship between the neck and vascular pedicle length. Viability could be determined by pre-operative measurements, where the clavicular length should be significantly greater than the distance from SC to MA.

Hatchet Thigh Flap with Hemi-gluteus Flap for Recurrent Ischial Sore Reconstruction

Background: Ischial pressure sores are the most challenging sores to treat because of associated bursa and high rate of recurrence. Reconstruction flaps originating in the thigh have a disadvantage as movement may increase shear forces, and tension during closure may lead to wound dehiscence. To circumvent these problems, we hereby present a hatchet thigh flap with good mobility, which can be used for recurrent cases as well.Methods: All patients treated at our hospital in the last 5 years for ischial pressure sores were included in the study. The flap is elevated in the subfascial plane from lateral to medial until the medial circumflex artery perforators are revealed. In recurrent cases the lower half of the gluteus maximus muscle is used to fill in the cavity while the flap from the previous surgery is re-advanced.Results: Sixteen patients (11 males and five females) were in the study. The median age of the patient was 54 years (range, 25–82 years). All the flaps survived fully. Two patients had recurrence at three sites, which were successfully reconstructed by advancing the same flap and hemi-gluteus muscle. An average of 6 months follow-up after surgery for recurrence showed stable reconstruction.Conclusion: The hatchet thigh flap is easy to dissect and reliable for ischial pressure sores. It can be used effectively in recurrent cases when combined with hemi-gluteus flaps.
