The infragluteal fold: An appraisal by MRI combined with an anatomic study.

PURPOSE: The gluteal region is a key element of beauty balance and sexual appearance. However, there is no clear anatomical description of the infragluteal fold, nor any classification exists allowing standardizing treatment of this area in case of jeopardisation. The purpose of this study was to perform an anatomical description of the infragluteal fold (IGF) matching radiological and anatomical findings in describing specifically raise of the fibrous component at the bone level. METHODS: Six volunteers (three males and three females) underwent an MRI scan (Siemens Aera® 1.5 T) of the pelvic region. T1 Vibe Morpho T2, Sag Space 3D, and Millimetric slices were performed in order to obtain a more detailed selection of the gluteal landmark. Trabecular connective tissue of the region was analyzed using Horos® ROI (region of interest) segmentation function. Four fresh cadavers (two males, two females, accounting for 8 hemipelvis) were dissected in order to compare the radiological findings. RESULTS: The infragluteal fold is a connectival fibrous band extending from the ramus of the ischium (but not involving the ischial tuberosity, for a length of 21 mm ± 2 and 21 mm ± 3), the apex of the sacrum (for a length of 13 ± 2 and 11 mm ± 2), and the coccyx (for a length of 19 mm ± 2 and 20 mm ± 2, all measures referring to volunteers and cadavers, respectively) reaching superficially the dermis of the medial one-third of the cutaneous fold. No significant difference was found between volunteer and cadaver group in MRI measurement of bony origins, or between MRI and cadaveric dissection measurements. CONCLUSION: Knowledge of this structure will define novel surgical techniques in infragluteal fold restoration.

Traumatic atlanto-axial rotatory subluxation after surgical correction of prominent ears: Case report and review of the literature.

Corrective surgery of prominent ears may be justified for social or aesthetic reasons during childhood or adulthood. Post-operative complications occur in approximately 0 to 8.4% of cases. This case describes a rare atlanto-axoid rotatory subluxation after bilateral surgical correction of prominent ears under general anesthesia. Orthopedic treatment was done after two months of medical roaming outside of our center. The one-year post-operative clinic consultation and radiological exam were normal. Only the psychological impact of the episode remained. Traumatic atlanto-axial rotatory subluxation is a rare complication but should be considered after post-operative torticollis in order to aid with diagnosis and allow doctors to implement the appropriate course of treatment.

Surgical approaches in neck dissection: Comparing functional, oncologic and aesthetic aspects of transverse cervicotomy to Paul André's approach.

BACKGROUND: Surgical approaches in neck dissection: comparing functional, oncologic and aesthetic aspects of transverse cervicotomy to Paul André's approach. METHODS: This single-center retrospective study compares a new transverse incision for cervicotomy to the classical approach described by Paul André in neck dissections. The evaluation criteria were: number of lymph nodes analyzed, operative time, complications, patient satisfaction and aesthetic aspects of the scar. RESULTS: A total of 34 patients were included in this study, from September 2009 until January 2015. The number of lymph nodes analyzed is not affected by this new approach compared to the classical one (P=0.9). The scar has a significantly more discreet appearance in the transverse cervicotomy group (P=0.023) likewise; patient satisfaction is higher in this group (P=0.006). CONCLUSIONS: Aesthetic and functional impairment can be reduced using this new transverse cervical approach hidden in the natural creases of the neck described by Langer.

[Custom-made implant for complex facial reconstruction: A case of total replacement of temporo-mandibular joint, zygomatic arch and malar bone]. / Reconstruction faciale complexe sur mesure : un cas de remplacement total de l'articulation temporo-mandibulaire, de l'arcade zygomatique et du zygoma.

INTRODUCTION: Total prosthetic replacement of the temporo-mandibular joint (TMJ) has become a common procedure, but it is usually limited to the TMJ itself. We report about one case of complex prosthetic joint reconstruction extending to the neighbouring bony structures. CASE: A 57-year-old patient, operated several times for a cranio-facial fibrous dysplasia, presented with a recurring TMJ ankylosis and a complexe latero-facial bone loss on the right side. We performed a reconstruction procedure including the TMJ, the zygomatic arch and the malar bone by mean of custom made composite prosthesis (chrome-cobalt-molybdenum-titanium and polyethylene). Five years postoperatively, mouth opening, nutrition, pain and oral hygiene were significantly improved. DISCUSSION: Nowadays technical possibilities allow for complex facial alloplastic reconstructions with good medium term results.

Functional and radiographic evaluation of the treatment of traumatic bone loss of the hand using the Masquelet technique.

This study was a retrospective evaluation of 18 patients with traumatic bone loss affecting the fingers, hand and wrist who were treated using the induced-membrane technique. Sixteen men and two women, mean age 54years (27-74) presented a hand injury including bone loss. Sixteen patients were treated on an emergency basis and two following nonunion of their fractures. There were 13 cases of open fracture of the phalanx and 5 cases of metacarpal fractures. These patients were treated with debridement and the injuries were covered when necessary. To address the bone loss, the first step of the induced-membrane technique involved placing a cement spacer (polymethylmethacrylate [PMMA]) without antibiotics in the defect. During the second step, the cement spacer was removed and replaced by autologous cancellous bone graft. The graft was placed within the biological tube left empty after removal of the cement. For each patient, bone union was assessed with radiographs and/or CT scan. Failure was defined as nonunion at 1year. In 16 patients, the fractures had healed after 4months (1.5-12months) on average. Two failures were noted (one nonunion treated using a PIP prosthesis and one case of delayed union). Mobility of the fingers, evaluated using the Total Active Motion (TAM) was 145° (75°-270°). The Kapandji score reached 8 for the thumb. Grip strength reached 21kg/F and pinch strength was 5kg/F; these values were 50% of those in the healthy hand. The induced-membrane technique is simple and can be used to treat traumatic bone loss in an emergency, thus avoiding amputation and limb shortening, while preserving limb function. It provides immediate stability and allows early mobilization.

[Pathomimia and plastic surgery, a case report]. / Pathomimie en chirurgie esthétique, à propos d'un cas.

Pathomimia is defined as a dummy pathology self-induced deliberately and is neither associated with mental confusion nor disturbance of consciousness. This article reports a case of pathomimia in plastic surgery. One of our patients had intentionally injected physiological saline solution into her breast implants in order to increase their volume. Implants removal was necessary because of severe local inflammatory signs. Psychiatric assessment revealed body dysmorphic disorder (BDD) developed on an hysterical personality, which explained the self-induced injuries. This nosologic entity must be promptly identified because it's diagnosis remains problematic and a multidisciplinary medical management is essential.

[Noma]. / Le Noma.

Noma is a necrotizing ulcerative stomatitis known since Antiquity. It occurs mostly in poor countries, the Sahel countries being the most affected. Each year, several hundred thousand cases are reported. Noma affects especially malnourished children who are less than 6 years old and rarely adults with acquired immunodeficiency (HIV, cancer). Ulcerative lesion is occurring rapidly due to the production of endotoxins by bacteria from oral commensal, telluric and animal origin. Necrotic debridement leads to huge defects: loss of soft tissue (skin, nerves, vessels, eye), bone (maxilla, mandible) and teeth. Death occurs rapidly in a few weeks in 80 % of the cases. In case of survival, the consequences are functional, aesthetic, psychological and social. The goal of the treatment in the acute phase is the patient's survival and the fight against limited mouth opening. The management of the phase of sequela is an anaesthetic, surgical and physiotherapy challenge. Its purpose is the social reintegration of the patient.

[Maxillofacial reconstruction with radial forearm osteofasciocutaneous free flap]. / Le lambeau ostéo-fascio-cutané antébrachial radial dans la reconstruction maxillo-faciale.

INTRODUCTION: Maxillofacial defects often affect various type of tissues and require reconstruction using composite flaps. The radial forearm osteofasciocutaneous free flap is one of the least used. We present the preliminary results of maxillofacial reconstruction using this free flap. MATERIALS AND METHODS: We reviewed the records of patients having undergone a radial forearm osteofasciocutaneous flap procedure between 2009 and 2011. Mandibular defect were staged according to HCL classification. Maxillary defects were staged according to Cordeiro and Santamaria's classification. Functional results (swallowing and speech) were assessed at the sixth month. RESULTS: The mean age of the 10 patients was 60.2 years. The average length of bone defect was 8 cm. The average cutaneous defect area was 36.8 cm(2). The mandibular defect was LCL in six cases, L in one case, and C in one case. The two cases of maxillary bone loss were classified IIIa. Six of the 10 microsurgical anastomoses were contralateral to the lesion. There was no reconstruction failure. Three patients had mild speech disorders, five had moderate speech disorders, and two major speech disorders. Four patients had a normal food intake, three patients needed mixed food, and three patients liquid food. DISCUSSION: The indications of radial forearm osteofasciocutaneous free flap for complex maxillofacial reconstructions should be extended. Its vascularization is less compromised by arteritis. Its pedicle may be long and adequate for a contralateral anastomosis. It is reliable and easy to harvest. But the bone quality is not as good as fibula.
