Comprehensive surgical management of cocaine-induced midline destructive lesions.

PURPOSE: This article presents a review of the literature and proposes a protocol for managing acute and chronic midfacial cocaine-induced injuries. MATERIALS AND METHODS: This report describes a series of 4 patients affected by cocaine-induced midline destructive lesions. Three patients came to the authors' attention after 18 months of drug withdrawal and underwent surgical treatments to restore nasal and palatal morphology and function, and the fourth patient was referred because of acute cocaine-induced destructive lesions and was treated by aggressive debridement. An 18-month drug-free period is planned before beginning any reconstructive procedures in this latter patient. RESULTS: Long-term follow-up showed stable results without relapse of palatal fistulas and good esthetic nasal appearance in all 3 patients undergoing reconstruction. The fourth patient did not show any disease progression and will be monitored for drug withdrawal. CONCLUSION: Chronic cocaine consumption may cause multiple types of damage to the soft and hard tissues of the midface. Acute lesions must be addressed with aggressive debridement. As a result of chronic injury, the palate and nose are deformed in a very complex way and the vascularity of the remaining local tissues may be compromised or inadequate for flap harvesting. Palatal and nasal reconstructions are very delicate operations and should be addressed separately to maximize the predictability of the result.

Surgical treatment of vascular malformations of the facial bones.

PURPOSE: To characterize intraosseous vascular malformations and describe the most appropriate approach for treatment according to clinical experience and a review of the published data. MATERIALS AND METHODS: We performed a retrospective review of 11 vascular malformations (7 venous and 4 arteriovenous) of the facial bones treated during a 10-year period using en bloc resection or intraoral aggressive curettage alone or preceded by endovascular embolization. Corrective surgery was planned to address any residual bone deformities. The cases were reviewed at a mean follow-up point of 6 years. RESULTS: Facial symmetry was restored in the cases requiring reconstruction. Tooth sparing was possible in the case of jaw and/or maxillary localization. Recanalization occurred in 14% of the venous and 33% of the arteriovenous malformations. CONCLUSIONS: Facial intraosseous venous malformations can be successfully treated using surgery alone. Facial intraosseous arteriovenous malformations will be better addressed using combined approaches. Aggressive curettage will obviate the need for extensive surgical resection in selected cases.

Recommendations for a safe restart of elective aerosol-generating oral surgery procedures following the COVID-19 pandemic outbreak: An Italian multicenter study.

Among healthcare workers, oral and maxillofacial surgeons are some of the most exposed to coronavirus disease (COVID-19). The aim of this retrospective study was to develop suggestions for continuing the work of oral and maxillofacial surgeons using a safe protocol for elective and urgent aerosol-generating procedures that could prevent the onset of new clusters. Based on the results obtained and a guidelines review of those Asian countries that had promptly managed the current pandemic, the following safety protocol was developed.

Extraoral approach to mandibular condylar fractures: our experience with 100 cases.

INTRODUCTION: Mandibular condylar fractures are very common. The current literature contains many indications and methods of treatment. Extraoral approaches are complicated by the need to avoid injury to the facial nerve. On the other hand intraoral approaches can make fracture reduction and/or fixation difficult. The mini-retromandibular approach provides an excellent view of the surgical field, minimises the risk of injury to the facial nerve, and allows rapid and easy management of condylar fractures. We have collected and reviewed our first 100 condylar fractures treated by means of a mini-retromandibular approach. PATIENTS AND METHODS: Between June 2006 and June 2012, Eighty-seven patients with extracapsular condylar fractures underwent open reduction and rigid fixation for 100 extracapsular condylar fractures via a mini-retromandibular approach. RESULTS: Dental occlusion and anatomic reduction were restored in all 100 condylar fractures. Postoperative infection developed in three patients. There was one sialocele and one case of plate fracture. Four patients experienced transient palsy of the buccal branch of the facial nerve. No permanent deficit of any facial nerve branch was observed. No patient showed condylar head resorption. CONCLUSIONS: Our experience with the treatment of the first 100 condylar fractures using the mini-retromandibular approach has demonstrated that this technique has allowed the Authors to safely manage extracapsular condylar fractures at all levels.
