Bimaxillary surgery rather than only mandibular setback surgery is preferable to correct class III jaw deformity to prevent narrowing of the pharyngeal airway, which might be a predisposing factor in the development of obstructive sleep apnea syndrome.
Background: panfacial fractures resembles a therapeutic challenge to maxillofacial surgeons This study was carried out to determine the etiology, injury characteristics and management outcome of pan facial fractures at Sohag university hospital.Methods: A retrospective hospital based study of panfacial fractures patients was carried out at Sohag university hospital from January 2010 to December 2016. Data was collected and analyzed using SPPS.Results: 200 Panfacial Trauma Patients were analysed. Males to females by a ratio of 24:1. Their ages ranged from 13 to 63 years with a mean of 30±12 years Most injuries were due to road traffic accidents (78%), and by falling from height in 12%. Mandibular fractures were the most common type of injuries. Open reduction and internal fixation by using plates and screws was the commonest surgical technique, used in 97.8% of cases. The most common complications were limited mouth opening, malocclusion. The mean duration of hospital stay was 11.13±2.23 days.Conclusions: Road traffic accident (RTC) was the most common cause of panfacial injuries in our locality and the young adult males were the most commonly affected victims. The majority of maxillofacial fractures were treated by open reduction and internal fixation.
Background: Early-stage oral cancers are usually treated with surgical resection and in most of cases the resulting defects are too large to be primarily reconstructed. There are many modalities of reconstruction as nasolabial flap, buccal bad of fat, polyglycolic acid sheets. Objective: This work aimed to evaluate the reconstruction of oral mucosal defects using either polyglycolic acid (PGA) sheet or nasolabial flap.Material and Methods: 51 patients of them 26 were reconstructed using (PGA) sheet, and 25 using nasolabial flap retrospectively. The tumors' location, perioperative situation, postoperative aesthetic and functional results were assessed. Results: There was no significant difference between the 2 groups regarding the early start of oral feeding or hospitalization time. While, the PGA group had significant shorter operative time. In cases with exposed bone surface, the PGA sheet was more feasible for reconstruction. There was no significant difference between the 2 groups in speech intelligibility in lingual cases. In buccal reconstruction the PGA sheets were more suitable for larger defects.
Conclusion:The optimal choice of nasolabial flap or PGA sheet depends on tumor location, mucosal defect size, the general condition of the patient and tolerability for surgery.
Background: Brown tumors are very rare giant cell lesions that arise as a result of hyperparathyroidism, brown tumors rarely affect the mandible and maxilla and its diagnosis and treatment is very challenging and needs a high index of suspicion. Methods: Retrospective chart review of nine cases diagnosed as brown jaw tumors treated in maxillofacial, head and neck surgery unit, department of surgery, Sohag University hospital. Results: They were 9 patients, 3 males and 6 females with a mean age of 43.3 years. Lesions were located in the mandible (4 cases), maxilla (3 cases), both mandible and maxilla (2 cases). The main presentation was a mass lesion. Clinical examination and serum parathormone, serum calcium, serum phosphorus, neck ultrasonography, parathyroid scan was used for diagnosis. Cases did excision with parathyroidectomy. There was no recurrence during a mean follow up period of 9.3 months. All patients had satisfactory results. Conclusions: All cases with osteolytic lesions in mandible or maxilla the possibility of brown tumors should be kept in mind especially if there is any manifestation of hyperparathyroidism. This report will aid in the recognition and treatment of the jaw brown tumors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
