Traumatic and Iatrogenic Retrobulbar Hemorrhage: An 8-Patient Series

Retrobulbar hemorrhage (RBH) is 1 of the 3 main causes of traumatic vision loss; the other 2 are direct penetrating injuries and traumatic optic neuropathy. The underlying causes of RBH are bleeding after trauma or a surgical intervention, although RBH can occur in the absence of orbital trauma, especially after maneuvers that increase blood pressure. The reorted incidence of RBH after blunt or penetrating rauma to the orbit or zygoma ranges from 0.45% to %. RBH can occur after surgery on or near the orbit, such as blepharoplasty (0.0052%), the treatment of facial fractures (0.3%), and endoscopic sinus surgery (ESS; 0.006%). RBH is an emergency that must be recognized and treated quickly. However, according to a recent report, only 17% of emergency senior house officers could identify RBH and perform first-line treatment. This article presents an 8-patient case series of traumatic and iatrogenic RBH.

Recovery of emotional smiling function in free-flap facial reanimation.

PURPOSE Long-standing unilateral facial palsy is treated primarily with free-flap surgery using the masseteric or contralateral facial nerve as a motor source. The use of a gracilis muscle flap innervated by the masseteric nerve restores the smiling function, without obtaining spontaneity. Because emotional smiling is an important factor in facial reanimation, the facial nerve must serve as the motor source to achieve this fundamental target. MATERIALS AND METHODS From October 1998 to October 2009, 50 patients affected by long-standing unilateral facial paralysis underwent single-stage free-flap reanimation procedures to recover smiling function. A latissimus dorsi flap innervated by the contralateral facial nerve was transplanted in 40 patients, and a gracilis muscle flap innervated by the masseteric nerve in 10 patients. All patients underwent a clinical examination that analyzed voluntary and spontaneous smiling. RESULTS All patients who received a latissimus dorsi flap innervated by the contralateral facial nerve and recovered muscle function (92.5%) showed voluntary and spontaneous smiling abilities. All patients who received a gracilis free flap innervated by the masseteric nerve recovered function, but only 1 (10%) showed occasional spontaneous flap activation. During those rare activations, much less movement was visible on the operated side than when the patient was asked to smile voluntarily. CONCLUSIONS The masseteric nerve is a powerful motor source that guarantees free voluntary gracilis muscle activation; however, it does not guarantee any spontaneous smiling. Single-stage procedures that use a latissimus dorsi flap innervated by the contralateral facial nerve have a lower success rate and obtain less movement; however, spontaneous smiling is always observed.

Ossification of vascular pedicle in fibular free flaps: A report of four cases

The fibular free flap is the most widely used flap for jaw reconstruction. Flap contouring requires removal of bone excess in the proximal segment by a subperiosteal dissection, preserving vascular connections between the pedicle and the bone and leaving well vascularized periosteum attached to the vascular pedicle. Among about 100 reconstructions with fibular flaps, 4 cases were observed of abnormal ossification along the vascular pedicle. Periosteum preserves its osteogenic capability after transposition, especially in a revascularized flap; this characteristic, together with the direct contact with the bone, allows the possibility of new bone formation along the pedicle. It would appear necessary to change the technique of reducing fibular excess, with removal of periosteum together with the bone, in order to avoid the complication described.

Mesenchymal phosphaturic neoplasm in the maxillary sinus: a case report

The authors describe a case of oncogenic osteomalacia due to a mesenchymal phosphaturic tumour in the maxillary sinus. This is a paraneoplastic syndrome in which a tumour produces a peptide hormone-like substance (phosphatonin) that causes a urinary loss of phosphates resulting in a debilitating systemic condition. In this case, the patient experienced muscle stiffness, reduction of muscle tone, loss of weight and pathological fractures. Clinical and radiological examination revealed a tumour in the right maxillary sinus; all other results were negative. The diagnosis following pathology examination was mesenchymal phosphaturic tumour with a haemangiopericytoma-like vascular pattern. Different histological types of mesenchymal tumours can be associated with paraneoplastic syndrome, but their localization in the paranasal sinuses is rare. The correct diagnosis allows the appropriate therapeutic approach, which can lead to an almost immediate resolution of the clinical situation after surgical removal of the neoplasm as in the present case. Oncogenic osteomalacia is rare, particularly in the maxillofacial region, and only a few cases have been reported.

Long-Term Follow-Up of UCLP Patients: Surgical and Orthodontic Burden of Care During Growth and Final Orthognathic Surgery Need

Objective The goal of this study was to evaluate the craniofacial morphology at 5 and 10 years of age and at the completion of growth, the need for final orthognathic surgery, and the orthodontic burden in a sample of patients with unilateral cleft lip and palate consecutively treated by the same surgeon with the same two-step protocol. Design A sample of 62 adult patients with unilateral cleft lip and palate was retrospectively collected (mean age, 17.5 years). Lateral cephalograms at three time points were traced. The need for orthognathic surgery was assessed, subdividing the sample into an orthognathic surgery group and nonorthognathic surgery group. Time and modality of orthodontic treatment were recorded. Results Cephalometric values related to maxillary growth (SNA, SNAns) and maxillomandibular relation (ANB, NAPg) were significantly different between the two groups already at 5 and 10 years of age. All patients presenting an ANB smaller than 2° at 5 years needed a Le Fort I osteotomy. Mandibular protrusion (SNB, SNPg) was not different at 5 and 10 years, but was different at the completion of growth. Patients with the same initial maxillomandibular relation did not show better growth when subjected to earlier or longer orthodontic treatment. Conclusion Patients needing final jaw surgery had a more severe skeletal discrepancy during early childhood. The ANB angle at 5 years allowed doctors to identify 45% of the need for orthognathic surgery. The final craniofacial pattern does not seem to change significantly with early or prolonged orthodontic treatment.

Deep-planes lift associated with free flap surgery for facial reanimation

Between April 1999 and April 2008, 37 patients with long-standing facial paralysis underwent a one-stage facial reanimation with neuromuscular free flaps: 28 patients (group A) underwent flap transposition only; 9 patients (group B) underwent a deep-planes lift (DPL) composed of the superficial muscoloaponeurotic system + parotid fascia at the time of facial reanimation. The postoperative and final results were compared between groups A and B, following the classification of Terzis and Noah (1997). Before the onset of contraction, only group B patients (100%) showed good or moderate symmetry at rest, while none of the patients of group A had a symmetric face. The respective final results for patients in groups A and B who already showed the onset of flap contraction were excellent in 28.6% and 44.5%, good in 42.9% and 33.3%, moderate in 10.7% and 22.2%, and fair or poor and fair in 17.8% and 0% of patients, respectively. The DPL allows immediate symmetry of the face at rest and contributes to upgrading the final static and dynamic results in facial reanimation with free muscular flaps.

Thoracodorsal nerve graft for reconstruction of facial nerve branching

OBJECT Surgical treatment of parotid malignancies may frequently involve facial nerve amputation to achieve oncological radical resection. The entire facial nerve branching from its exit from the stylomastoid foramen to the periphery of the gland is often sacrificed. The first reconstructive strategy is the immediate reconstruction of the facial nerve by directly anastomosing the trunk of the facial nerve to its distal branches by interpositional nerve grafting. The present study was performed to determine the adequacy of thoracodorsal nerve grafting for immediate repair of the facial nerve. The anatomical features of the thoracodorsal nerve make it particularly appropriate to match its trunk to the stump of the facial nerve at its exit from the stylomastoid foramen. Up to seven branches of the thoracodorsal nerve may be distally anastomosed to the severed distal branches of the facial nerve. More complex reconstruction may be addressed simultaneously by contemporary harvesting a de-epithelialized free flap from the same site based on thoracodorsal vessel perforators and preparing a rib graft from the same donor site. METHODS Between October 2003 and August 2010, seven patients affected by parotid tumors (6 with parotid malignancies and 1 with multiple recurrences of pleomorphic adenoma) underwent radical parotidectomy with intentional sacrifice of the facial nerve to obtain oncological radical resection. In all patients, the facial nerve was reconstructed with an interpositional thoracodorsal nerve graft. In four patients, a de-epithelialized free flap based on the latissimus dorsi was transposed to cover soft tissue defects. Moreover, two of these patients also required a rib graft to reconstruct both the condyle and ramus of the mandible. With the exception of one patient affected by recurrent pleomorphic adenoma, all patients underwent radiotherapy after surgical treatment. RESULTS All patients in our study recovered mimetic facial function. Facial muscles showed clinical signs of recovery within 5-14 (mean: 7.8) months, with varying degrees of mimetic restoration, and almost complete facial symmetry at rest in all patients. The House-Brackmann final score was I in two patients, II in two patients, and III in three patients. CONCLUSIONS A thoracodorsal nerve graft to replace extratemporal facial nerve branching is a valid alternative technique to multiple classical nerve grafts, with good matching at both the proximal and distal anastomoses.

Use of Buccinator Myomucosal Flap in Tongue Reconstruction

Abstract The myomucosal buccinator flap, first described by Bozola in 1989, has become an important tool for intraoral defects reconstruction. In the literature, there is a variety of proposed myomucosal cheek flaps, both pedicled and island, based on the buccal or the facial arteries. From January 2007 to December 2011, the authors used a pedicled buccinator flap based posteriorly on the buccal artery to reconstruct partial lingual defects following tumor resection in 27 patients. The buccal fat pad was translated to cover the donor site defect. After 3 to 4 weeks from the original surgery, a second procedure under local anesthesia was performed to detach the pedicle and remodel the flap. The morphological and functional outcomes of the procedures were evaluated by the surgeons and a speech and language therapist. All patients presented satisfactory results. The authors consider the use of the described technique as the gold standard in the reconstruction of partial tongue defects after tumor resection.

Reconstruction of complex defects of the parotid region using a lateral thoracic wall donor site.

Radical treatment of parotid neoplasms may lead to complex parotid defects that present functional and aesthetic reconstructive challenges. We report our experience using the lateral thoracic wall as a single donor site. Between 2003 and 2009, four patients with malignant tumours in the parotid gland underwent radical parotidectomy and simultaneous reconstruction using a perforator latissimus dorsi cutaneous free flap (de-epithelialized and entire skin paddle in two cases each). A thoracodorsal nerve graft was used in all cases to replace the intraglandular branches of the facial nerve. Costal grafts were used for mandibular reconstruction in two patients. All patients underwent postoperative physiotherapy. No donor-site complication occurred and all treatments achieved good aesthetic results. All patients recovered nearly complete symmetry at rest and partial facial mimetic function. The lateral thoracic wall is a good donor site for the reconstruction of complex parotid defects.

Short- and Long-Term Effects of Late Maxillary Advancement With the Liou-Alt-RAMEC Protocol in Unilateral Cleft Lip and Palate

Objective: The objective of this retrospective longitudinal study was to evaluate short- and long-term results of the application of the Liou Alt-RAMEC (alternate rapid maxillary expansion and constriction) technique, a late orthopedic maxillary protraction technique, with intraoral anchorage, in patients with cleft. Materials and Methods: Twenty-six patients with unilateral cleft lip and palate (UCLP) were consecutively treated with the Alt-RAMEC technique. The average age of the patients was 11.7 years (10.3-13.2 years) before protraction and 18.3 years (17.4-21.1 years) at long-term follow-up. A sample of nontreated patients with UCLP was used as a control group. It was matched for sex, skeletal class III, and age (11.3 years). The control sample had records at the end of growth (18.7 years). Results: The sagittal advancement of A-point, after the application of the technique, was 5.7 (2.17) mm. Some mandibular dentoalveolar and positional adaptation was noted. The position of the maxilla was stable in the long term. On the other hand, the UCLP control group showed hardly any growth at the maxillary level during the long-term follow-up period. Conclusion: Our results showed that the Alt-RAMEC technique, performed at the correct time, with a double-hinged expander, followed by class III spring or elastic traction, 24 hours per day, allows for satisfactory maxillary protraction, with, at this stage, apparently stable long-term results. Nevertheless, as only 50% of the patients had long-term follow-up data, we are still unable to predict the percentage of patients which will not eventually need orthognathic surgery.
