The purposes of this study were (1) to document outcome after primary fronto-orbital advancement for the four major eponymous craniosynostotic syndromes (Apert, Crouzon, Pfeiffer, and Saethre-Chotzen) and (2) to identify factors that might influence need for primary and secondary fronto-orbital advancement or foreheadplasty. Also tested was the hypothesis that coincident sagittal synostosis could modulate brachycephaly and affect whether a primary or secondary frontal operation was necessary. Data were collected on age and indications for initial operation, type of primary and secondary frontal procedures, and concomitant sagittal synostosis. Patients initially managed by subcranial Le Fort III were included in the study group but excluded from analysis of fronto-orbital advancement. Patients treated by monobloc advancement or Le Fort III osteotomies with frontal grafting or Anderl modification were assessed as having had primary fronto-orbital advancement. Minimum time to follow-up was 5 years. A total of 126 patients met inclusion criteria. Lateral photographs were examined to assess preoperative and postoperative sagittal position of supraorbital rims-to-globes. Frontal re-advancement was indicated if the corneal apex was anterior to the supraorbital rim. Foreheadplasty was indicated for unacceptable frontal contour and normal supraorbital rim-to-globe relationship. Primary correction for frontal retrusion was not required in 4 percent of Apert (1 of 25), 16 percent of Crouzon (7 of 44), 6 percent of Pfeiffer (2 of 31), and 19 percent of Saethre-Chotzen (5 of 26) patients. Of those infants who had a primary fronto-orbital advancement, reoperation for either supraorbital retrusion or frontal deformity was necessary in all 16 Apert patients and in 5 of 19 Crouzon (26 percent), 10 of 26 Pfeiffer (38 percent), and 13 of 20 Saethre-Chotzen (65 percent) patients (p < 0.001). Age at initial fronto-orbital advancement did not influence reoperative rate. No correlation was found between concomitant sagittal synostosis and necessity for primary or secondary frontal correction (p = 0.22). In summary, phenotypic diagnosis was determinant for outcome as defined by need for secondary fronto-orbital advancement, foreheadplasty, or both. Apert patients had the highest incidence of reoperation for frontal retrusion or forehead contour. Crouzon and Saethre-Chotzen patients were most likely to express a minor phenotype and not require fronto-orbital correction. Coincident sagittal synostosis did not influence frontal projection, as reflected in need for either primary or secondary frontal advancement.

As the technique of autologous fat grafting is being refined and perfected, its clinical applications are expanding. The use of autologous fat grafting for primary breast augmentation is controversial due to a lack of clarity regarding its safety and efficacy. Most notably, concerns about interference with the detection of breast cancer have been raised, but these have not been clearly addressed in the literature. To help surgeons gain further insight, the authors conducted a systematic review of the literature, carefully comparing technique, clinical outcome, radiologic impact, and complications in all available data on this subject. Although an optimal method of autologous fat grafting for primary breast augmentation is yet to be standardized, further strong evidence-based studies are necessary to confirm the findings of this approach.

The transantral endoscopic orbital floor approach can be used to repair pure orbital floor blowout fractures, avoiding the risks of lower lid incisions. A transoral incision is made to expose the anterior maxillary wall. A 1-cm2 antral bone flap gives access to the maxillary sinus and infraorbital floor. The size and fracture configuration are defined using a 30-degree, 4-mm endoscope. Stable bony shelves are identified adjacent to the fracture. Resorbable bone plating material is cut slightly larger than the defect. The material is introduced through defect, rotated, and allowed to rest on the stable medial, lateral, and anterior orbital shelves. Fixation is not required if there is adequate stability of the bony shelves. If not, direct screw fixation can be done from below.

A cadaver and clinical study was performed to determine the value of transantral endoscopy in diagnosis and treatment of orbital floor fractures. Six fresh cadaver heads were dissected using a 30 degree, 4-mm endoscope through a 1 cm2 antrotomy. In the cadaver, the orbital floor and the course of the infraorbital nerve were easily identified. The infraorbital nerve serves as a reference point for evaluation of fracture size; three zones of the floor are described that are oriented relative to the infraorbital nerve. In the clinical study, nine patients with orbital floor fracture initially underwent endoscopy at the time of fracture repair: three patients had comminuted zygomatico-orbital fractures, five had monofragmented tetrapod fractures, and one had an isolated orbital blowout fracture. Endoscopic dissection of the orbital fractures revealed seven fractures with an area > 2 cm2 and two fractures with an area of < 2 cm2. The isolated orbital floor blowout fracture had entrapped periorbital tissue, which was completely reduced endoscopically. A separate patient with a < 2 cm2 displaced fracture also had stable endoscopic reduction. In the remaining seven patients, the endoscopic technique assisted with the floor reconstruction by identifying the precise fracture configuration as well as identifying the stable posterior ledge of the orbital floor fracture. There have been no complications in any of our patients to date. We conclude: (1) Transantral orbital floor exploration allows precise determination of orbital floor fracture size, location, and the presence of entrapped periorbita. The information obtained through endoscopic techniques may be used to select patients who would not benefit from lid approaches to the orbital floor and may possibly eliminate nontherapeutic exploration. (2) Transantral endoscopic orbital floor exploration assists the reduction of complex orbital floor fractures and allows precise identification of the posterior shelf for implant placement. (3) Transantral endoscopic techniques can completely reduce entrapped periorbital tissue caught in a trapdoor type of fracture.
