Ultrasonographically determined pedicled breast reduction in severe gigantomastia.

Background: The free nipple breast reduction method has certain disadvantages, such as nipple hyposensitivity, loss of lactation, and loss of projection. To eliminate these risks, the authors describe a patient-based breast reduction technique in which the major supplier vessels of the nipple-areola complex were determined by color Doppler ultrasonography. Pedicles containing these vessels were designed for reductions. Methods: Sixteen severe gigantomastia patients with a mean age of 41 years (range, 23 to 60 years) were included in the study. Major nipple-areola complex perforators were determined with 13- to 5-MHz linear probe Doppler ultrasonography before surgery. Pedicles were designed according to the vessel locations, and reductions were performed with superomedial-, superolateral-, or mediolateral-based designs. Results: Different combinations of internal mammary and lateral thoracic artery perforator–based reductions were achieved. None of the patients had areola necrosis. Mean reduction weight was 1795 g (range, 1320 to 2280) per breast. Conclusions: Instead of using standard markings for severe gigantomastia patients, custom-made and sonographically determined pedicles were used. This technique can be considered as a “guide” for the surgeon during very large breast reductions.

Electrothermal Bipolar Vessel Sealer in Endoscope-Assisted Latissumus Dorsi Flap Harvesting

LigaSure™ is a new bipolar vascular sealing system commonly used in various fields of surgery. However, no reports have been published about its use in plastic surgery, particularly for endoscopic flap harvesting. In this study, we present the use of LigaSure in endoscope-assisted latissimus dorsi (LD) flap harvesting for breast reconstruction. Between 2006 and 2008, 11 female patients with the mean age of 33.4 (range, 20-49 years) who had previously undergone mastectomy operations were included in the study. First stage of reconstruction was performed with the ipsilateral LD harvested by the help of LigaSure and a tissue expander placed beneath the LD and pectoralis major muscles. Secondary reconstruction was done by a definitive silicon gel-filled implant placed after an average of 6.6 months of expansion (range, 6-9 months). Data concerning the hospitalization and operation times, drainage amounts, complications, etc., were recorded. Mean follow-up was 13 months (range, 8-18 months). Mean flap harvesting time was recorded as 74.2 minutes (range, 50-125 minutes), which shortened as the surgeon got used to the procedure. Patients were hospitalized for 3-7 days, with a mean hospitalization period of 5.5 days. The total mean drainage amount postoperatively was found to be 950 mL (range, 725-975 mL), which is relatively lower than the previously reported values. LigaSure use in endoscope-assisted LD harvesting is easy, safe, and time sparing with almost no complications observed in this small initial series. Although more controlled studies with larger number of patients need to be done to verify its effectiveness in terms of hospitalization, drainage amounts, etc., it holds promise for a wide spectrum of operations in the field of plastic surgery.

A custom-made silicon mold for pressure therapy to ear keloids.

Keloids are raised reddish nodules that develop at the site of an injury. They are characterized histologically by an abundance of fibroblasts, thick collagen bundles, and ground substance. Auricular keloid formation is a known complication of ear piercing. Many types of treatments have been described for auricular keloids. Pressure therapy in combination with surgery, corticosteroid injection, or both is widely used to manage and prevent hypertrophic scarring. Many pressure devices and procedures have been developed. However, all of them are designed for the earlobe region. If a keloid grows in the posterior auricular region, none of the devices described in the literature will be effective. The authors developed a custom-made silicon ear mold that covers whole ear. With this mold, pressure can be applied homogeneously to the lobule and cartilaginous region, which the other devices described in the literature cannot affect. The preparation technique includes making the negative cast mold of the patient’s ear, creating the positive cast mold from the negative cast mold, and forming the negative silicon mold from the positive cast. After all the processes, a silicon sheet has been designed according to the region needing to be pressurized. The designed silicon sheet is applied to the region, followed by placement of the silicon mold. A simple tennis headband can be used to stabilize the silicon cast. If the keloid extends to the posterior auricular region, pressurizing with clips or other devices described previously will be difficult. Application of pressure to the cartilaginous auricle needs custom-made devices. At this point, a pressure sore caused by a device applied to the ear is the most important problem. To prevent the ear from developing a pressure sore, the device should press to whole area homogeneously. For this reason, the device applied for pressure therapy to the ear must be custom made.

Facial contour reconstruction with temporoparietal prelaminated dermal–adipose flaps

AIM Compared with those for free-fat grafts, resorption rates for vascularized adipose tissue transfers are very low. We analysed benefits of transfer of dermal-adipose grafts after prelamination upon the temporal fascia in reconstruction of facial contour defects. PATIENTS AND METHODS Among 8 patients operated on between 2005 and 2008, facial contour anomalies had resulted from trauma in 5, while the remaining 3 had abnormalities with a congenital, postinfectious, or iatrogenic aetiology. In the first-stage operation, a dermal-adipose graft was taken from the inguinal region and prelamination upon the superior surface of the temporal fascia. After 5.5 months, the prelaminated dermal-adipose-fascial flap was raised as an island flap, passed through a subcutaneous tunnel in the temporal region, and set into the defect site. RESULTS Satisfactory cosmetic results were achieved in all patients. Except for a temporary frontal nerve palsy in 1 patient, no early or late complications resulted from this procedure. CONCLUSION Prelamination of dermal-adipose grafts upon the temporoparietal fascia is useful in reconstruction of soft tissue defects requiring volume augmentation.

Quadruple salivary duct diversion for drooling in cerebral palsy.

Abstract Drooling complicates many neurologic disorders including cerebral palsy. It is socially debilitating for the patient and very tedious for the caregiver. Surgical treatment consists mainly of ablative (excision/ligation) or physiological (diversion) methods; combined techniques have also been proposed. We have applied bilateral diversion of both submandibular and parotid ducts in 12 cerebral palsy patients (age range, 7–15 years). Preoperative drooling severity was grade 4/5 in 10 cases and grade 5/5 in 2 of the cases. All patients underwent physiotherapy for a minimum of 6 months and were consulted with a dentist, otolaryngologist, and a speech therapist before surgery. No bleeding, hematoma, or infection has been observed in any of the patients. Two patients had early postoperative tongue edema that regressed with conservative treatment. All patients except one regressed to grade 2/5 drooling by the first postoperative month. In 1 patient who had previously been classified as grade 5/5, surgery provided limited improvement with only 1 grade of step-down. Satisfactory results for the patients and their families could be achieved and sustained for a median 18 months (7–20 months) of follow-up. In conclusion, the quadruple duct diversion method is an effective physiological surgical method in the control of drooling in cerebral palsy.

Preventing Suture Extrusion and Recurrence in Mustarde and Furnas Otoplasties by Using Laterally Based Postauricular Dermal Flap, Long-Term Results.

Background:Prominent ear deformity (PD) is an unacceptable condition of pinna that affects 5% of the population and is associated with emotional stress, behavioral disturbances, and social restrictions in relationships. Conchal hypertrphy, inadequate formation of antihelical fold, earlobe placement ahead than it should be, or various combinations of these changes are main characteristics of PD. Many surgical techniques have been described for the PD.The authors’ aim was to present laterally based postauricular dermal flap combination with cartilage-sparing methods and effectiveness of this technique in suture extrusion prevention and reducing the rate of recurrence with long-term results. Methods:Forty-one patients had bilateral and 6 patients had unilateral PD, a total of 47 patients with a mean age of 14.48 were operated by using this combined procedure. A laterally based supraperichondrial dermal flap was prepared from a deepithelized elliptical postauricular incision. Mustarde and Furnas suture techniques were used solely for PD correction. The dissected laterally based dermal flap was fixed to the mastoid bone with sutures in stretched position after reshaping the auricular cartilage with sutures. Results:The average helix–mastoid distance was (mm) 16.28 ± 2.36, concha-mastoid angle was 25.71 ± 0.96° on 12-month measurements. The helix–mastoid distance showed an increase of 1 to 3 mm, in the concha-mastoid angle measurements of 1° to 2°. Statistically significant changes were observed between the average preoperative, postoperative 1. month, postoperative 12. month helix–mastoid distances (mm), and month concha-mastoid angle (°) measurements (P = 0.0001). Conclusions:The laterally based postauricular dermal flap technique is an effective method to prevent suture extrusion and recurrence which are the most important complications of otoplasty procedure and easy to apply.

Cosmetic closure of pilonidal sinus defects with bilateral transpositional adipofascial flaps

Abstract The optimal treatment of the pilonidal sinus has not currently been defined. This study described the use of a modified bilateral transpositional adipofascial flap technique that effectively serves to flatten the deep natal cleft while keeping the scar limited to the intergluteal fold for good cosmesis. Between June 2007 and September 2011, 83 patients (61 men, 22 women) were included in the study. Duration of pilonidal sinus symptoms ranged from 1–15 (median 5) years; 15 patients had recurrent disease. Before the operation, perforating branches of the four pairs of lateral sacral arteries were identified with a Doppler audioscope. After complete excision of the sinus cavity and adequate undermining of the skin, bilateral adipofascial flaps were raised in order to realise a Yin-Yang pattern, with the lateral sacral artery perforators at the base of each flap. Complementary flaps were then transposed into the defect and inset to completely obliterate dead space. Skin was closed primarily in two layers. The median (range) defect size after total excision of the sinus cavity was 38 (19–60) cm2. All flaps survived. There was no wound infection or dehiscense. Median (range) follow-up was 26 (6–52) months. No recurrences were observed. Extensive scarring or asymmetry in the gluteal prominences was not observed. Transient paraesthesia over the flap donor region occurred in 14 cases (16%) and resolved completely within 6 months. The bilateral adipofascial transpositional flap method is an alternative to previously described treatment options in pilonidal sinus surgery. It is a safe, reliable, and easily applicable method, which provides cosmetically acceptable coverage of pilonidal sinus defects of moderate size.

Key and Keyhole Model for Dorsal Onlay Cartilage Grafts in Correcting Nasal Deformities.

BackgroundThe shaping of the cartilage and keeping it in place is very significant for patients who need nasal reconstruction with costal grafts at traumatic or secondary rhinoplasties. In this study, a template is prepared during the surgery that shows the dorsal defect in a 3-dimensional manner and acts as a guide while shaping the cartilage. MethodsSeventeen patients who required secondary rhinoplasties because of trauma or previous operations were included in this study. The patients were operated on between the years 2009 and 2013. The mean age of the patients was 24 years (19–38 years). According to the surgical technique, bone wax was placed in a sheath prepared from the finger of a sterile nylon surgical glove before the dorsal reconstruction. It was placed to the nasal dorsum and shaped over the skin with digital maneuvers. Afterward, the bone wax was stripped off the nylon glove, and it was used as a template to shape the cartilage graft. ResultsNo need for revision rhinoplasties was seen in any of the patients during the mean follow-up period of 19 months. The patients stated that they were satisfied by both the functional and the aesthetic results. ConclusionsThe bone wax template and the defect fit in a key and keyhole fashion. It is supported by multiple points on the nasal bone and the septum. Thus, it does not slide and its warping is avoided. We think that it gives satisfactory results and it shortens the learning process.

Creating a neoconchal complex using the adjustable conchal sliding technique in prominent ear correction.

Abstract An oversized aural concha plays a significant role in prominent ear deformities and should be taken into consideration during preoperative examination. In the current study, we present a procedure known as the conchal sliding technique as an alternative to more disruptive methods. Twenty-four patients (9 females and 15 males; 47 ears in total) underwent a conchal sliding procedure between 2006 and 2010. During the surgery, a wide subperichondrial dissection is performed after a posterior elliptical incision. After the concha is exposed as a hemisphere, it is split along its long axis to reveal the medial and lateral cartilage segments. These segments are gently scrolled upon each other. Transposition of the lateral segment posteriorly to the medial segment replaces the whole ear toward the posterior direction. Three mattress sutures (4–0 polypropylene) reliably secure the repositioned and setback conchal bowl. If needed, an antihelix can be formed using neoconchal-scaphal mattress sutures. Median follow-up period was 24.3 months (range, 6–48 mo). A unilateral hematoma developed in 1 patient and an anterior step deformity occurred in another. No recurrence, infection, necrosis of the skin, distortion of the auditory canal, or formation of keloid was observed in any of the patients. The median cephaloauricular angle was measured as 46 degrees before the surgery and 26 degrees after the surgery, whereas the distance between the helix and the mastoid was 23 mm before the surgery and 11 mm after the surgery. All the patients were satisfied with the results. This technique provides stable and natural results by creating a safe neoconchal complex. It may be a safe and reliable solution to an oversized aural concha, enabling natural-looking and positive cosmetic results.

The Effects of Mucoperichondrial Flap Elevation on Septal L-strut Cartilage: A Biomechanical and Histologic Analysis in a Rabbit Model

Background: The harvesting of septal cartilage following mucoperichondrial flap elevation has almost become a standard step in rhinoplasty. However, the strength of the remaining septum has not yet been evaluated. In the current experimental study of a rabbit rhinoplasty model, the remaining septum following a graft harvest was analyzed both biomechanically and pathologically. Methods: Forty New Zealand rabbits were classified into four equal groups. Group 1 consisted of the animals in which unilateral elevation of the mucoperichondrial flaps was undertaken before the graft harvest, group 2 consisted of the animals in which bilateral elevation was undertaken, group 3 included the animals where the septum was exposed and left untouched after a bilateral mucosal flap elevation, and group 4 was designated as the control group. Specimens were analyzed under light microscopy for multiple parameters. Biomechanical analyses were performed with a universal testing device at the Department of Engineering, Biomechanical Laboratories, Istanbul Technical University. Results: Biomechanical analysis in terms of maximum tension revealed significant results among the groups (p = 0.008). Although insignificant results were observed overall using a pathologic analysis, the amount of chondrocytes was lower in group 2 than in group 1 (p = 0.099). The amounts of matrix collagen (p = 0.184) and fibrosis were (p = 0.749) higher in group 2 than in group 1. Conclusions: From these data, the authors conclude that mucoperichondrium integrity plays a crucial role in the biomechanical strength of the septum. More sophisticated studies with further pathologic analysis are required to determine the exact mechanism of strength loss observed with mucoperichondrial flap elevation.
