Assessment of the Outcome of Calvarial Vault Remodeling and Spring-Mediated Cranioplasty in the Correction of Isolated Sagittal Suture Synostosis.

BACKGROUND: Sagittal synostosis is the commonest form of nonsyndromic isolated craniosynostosis. Calvarial vault remodeling (CVR) and spring-mediated cranioplasty (SMC) are the commonly used correction techniques. AIM OF THE WORK: To study and compare clinical and radiographic outcomes of CVR and SMC in the correction of isolated sagittal suture synostosis. METHODS: A prospective cohort with the patients were divided into group; I (SMC) and II (CVR), each 15 patients. They were observed to evaluate the outcome and detect complications. RESULTS: Mean operative time was 59.2 minutes in SMC and 184 minutes in CVR. Mean intraoperative blood loss was 26 mL in SMC and 64.7 mL in CVR. Intraoperative complications in SMC were dural tear in 1 patient and superior sagittal sinus injury in another patient, while in CVR 2 patients with dural tears and a 3rd with superior sagittal sinus injury. Postoperative complications in SMC were exposed spring, gaped wound, and parietal eminence elevation, while in CVR 2 patients needed blood transfusion. The mean hospital stays was 1.4 days in SMC and 4.1 days in CVR. In SMC, the relative increase in cephalic index varied between 5.5% and 8.2%, while for CVR, it varied between 5.1% and 7.9%. CONCLUSION: The SMC and CVR are safe procedures, with good long-term results and significant objective changes toward normalization of the skull morphology in isolated sagittal craniosynostosis. The SMC is less invasive and associated with reduced hospital stays, decreased blood loss, and can be performed at a younger age than CVR with a lower morbidity.

The Outcome of Multidisciplinary Management of Carotid Body Tumors: Retrospective Cohort Study.

BACKGROUND: Carotid body tumor (CBT) is a rare paraganglionic hyper-vascular tumor of the carotid body. The standard treatment for CBTs is surgery, but it involves risk. The study is aimed to assess the CBTs and evaluate the outcome of multidisciplinary management. MATERIALS AND METHODS: A retrospective cohort study included patients with CBTs who were managed by surgical excision between May 2006 and April 2018. A multidisciplinary team was established to excise the tumor completely with minimal neurovascular compromise. RESULTS: The study comprised of 32 patients in the age group of 23-65 years. The main presentation was a unilateral painless neck mass. Six cases (18.75%) were Shamblin I, 10 (31.25%) Shamblin II and 16 (50%) Shamblin III. Complete excision was performed for all cases. Ligation of the external carotid artery was done in 15 cases (46.88%) and repair of the internal carotid artery in 6 (18.75%). Postoperative cranial nerve complications occurred in six patients (18.75%): four transient hypoglossal pareses and two hoarseness of voice. Histopathologically, one case (3.125%) was malignant. No recurrence was detected through the follow-up period. CONCLUSION: A multidisciplinary approach is essential for management of CBTs. Early diagnosis and surgical resection minimize morbidity and carry good surgical outcome. TRIAL REGISTRATION NUMBER: ChiCTR1800018722 (Agency: Chinese Clinical Trial Registry).

Controversy on the Age of Hypertelorism Correction.

INTRODUCTION: Orbital hypertelorism (HTO) is a challenging craniofacial problem seen in association with some congenital deformities. The age of HTO correction is a matter of debate. THE AIM OF THE WORK: to evaluate the outcome of HTO correction and determine the optimal timing for intervention, striving for the earliest possible intervention with the lowest relapse. PATIENTS AND METHODS: A standard craniofacial approach with medial bone resection, 4 walls orbital box osteotomy and orbital medialization were done for all patients. Skeletal and soft tissue procedures were done as indicated. RESULTS: there were 10 patients aging 6 to 19 years. Seven were associated with craniofacial clefts, and 3 with craniosynostosis syndromes. HTO was severe in 8 cases and moderate in 2 cases. It was asymmetric in 2 cases. Frontoorbital remodeling was done in 3 cases with craniosynostosis. Failed surgery was reported in 2 cases. A redo surgery was done for one of them with an excellent outcome, while refused by the other. Nine patients had an excellent outcome. The mean level of satisfaction was 93.37%. Three patients had ugly facial scars. No major complications were recorded. CONCLUSION: The time for surgical treatment of HTO is determined by the severity of the associated deformity. If there is an urgent factor indicating intervention, early correction can be performed exceptionally; otherwise, HTO correction should be performed after the age of 6 years.

Single-Stage Combined Craniofacial Repair for Frontoethmoidal Meningoencephalocele.

INTRODUCTION: Frontoethmoidal meningoencephalocele (FMEC) is a rare congenital anomaly characterized by herniation of brain tissue and meninges through a defect in the cranium and associated with facial dysmorphism. Treatment modalities include extra cranial, transcranial, or combined craniofacial approaches. The combined approach is considered the best treatment choice. METHODS: Twelve patients with FMEC aging from 6 months to 4 years were treated by single-stage combined craniofacial approach between July 2011 and July 2015. They were followed up for evaluation of outcome and detection of complications. RESULTS: Seven patients (58.3%) were males and 5 patients (41.7%) were females. Eight patients (66.7%) were less than 2 years while 4 patients (33.3%) were between 2 and 4 years. The main presentations were external mass, telecanthus and hypertelorbitism, radiologically, frontobasal bone defect and herniated dural sac with brain tissue were detected in all patients. Excision of the mass with dural repair, craniofacial reconstruction, and medial canthopexy were done for all patients. Orbital translocation was done for 8 patients (75%), nasal reconstruction for 7 patients (58.3%), while dacryocystorhinostomy in 3 patients (25%). Venticuloperitoneal shunt was done before correction of FMEC in one patient (8.3%). The follow-up period ranged from 6 to 48 months with mean 29.2 months. The esthetic results were satisfactory in 9 patients (75%). Ugly facial scars were recorded in 3 patients (25%). CONCLUSION: Early surgical management for FMEC is advisable to avoid deleterious effects on facial growth. Meticulous perioperative care is important for successful surgery. The authors recommend combined craniofacial approach to achieve good outcome and decrease the incidence of complications.

Orbitocranial Fibrous Dysplasia: Outcome of Radical Resection and Immediate Reconstruction With Titanium Mesh and Pericranial Flap.

INTRODUCTION: Fibrous dysplasia (FD) is a non-neoplastic developmental fibro-osseous disease. It represents 2.5% of all bone tumors and 5% to 7% of the benign bone tumors. Orbitocranial region is involved in about 20% of the patients. The main presentations are craniofacial deformity and headache. Loss of vision is the most devastating result of this disease. There is no medical treatment to cure or prevent FD. Radiation therapy is contraindicated. Surgery for the orbitocranial FD is often challenging because of the proximity of neurovascular and ocular structures. Conservative surgical shaving and recontouring is always associated with suboptimal results. Radical excision is potentially curative with no extra morbidity. Orbital hypertelorism, dystopia, or proptosis can be corrected only by radical excision and reconstruction. AIM: The aim of the study was to evaluate the outcome of radical excision of the orbitocranial FD and immediate reconstruction using titanium mesh and pericranial flap. PATIENTS AND METHODS: This prospective study had been conducted on 22 patients with orbitocranial FD with age range from 17 to 52 years (mean 29.5). Radical excision of the lesions was done for all patients through transcranial approach. Immediate reconstruction was achieved using titanium mesh and pericranial flap. RESULTS: Intraoperative dural tears and cerebrospinal fluid leak were reported in 2 patients and repaired with galeal graft. Supraorbital anesthesia occurred in 6 patients. Of these, 2 patients were transient, while the remaining 4 patients were permanent. Wound infection was noticed in 1 patient who improved by medical treatment. Temporary postoperative diplopia occurred in 1 patient and temporary postoperative impaired vision in 1 other patient. In all patients, acceptable or good aesthetic results were observed. No recurrence was detected in our series during the follow-up period that ranged from 24 to 58 months (mean 37.5 months). CONCLUSION: Radical excision of orbitocranial FD is potentially curative with no extra morbidity. It can achieve good aesthetic and functional results with no recurrence.
