A systematic review and meta-analysis of the surgical outcomes in patients with osteochondroma of mandibular condyle.

Many options exist in the diagnosis and management of condylar osteochondroma. The purpose of this study was to provide a congregate information concerning treatment of the osteochondroma involving the mandibular condyle. The search was conducted in PubMed, Google Scholar, Semantic Scholar, and Cochrane database until February 2022. Twenty-seven studies were included for the final review. The review included 439 patients who underwent surgical management for mandibular condylar osteochondroma. The position of osteochondroma was mentioned in 13 studies. Preauricular, retromandibular, endaural, submandibular, transzygomatic, and intraoral approaches were used for approaching the tumor. Surgical techniques included resection, conservative condylectomy, and total condylectomy. Concomitant orthognathic surgery was performed along with tumor resection in 19 studies. In the entire review, the recurrence rate was 0.22% (1/439). The results of the meta-analysis showed that 2 studies reported significant malocclusion events after surgical therapy. Total joint replacement after tumor resection has a higher improvement in maximal mouth opening (8 mm) compared with vertical ramus osteotomy and no reconstruction groups, which have similar improvements (6 mm). The mainstay of treatment of osteochondroma is surgical excision either as condylectomy or conservative condylectomy. Among the various reconstruction modalities, total joint replacement showed better improvement in mouth opening. Adjunct procedures like orthodontic and orthognathic surgery have an important role in holistic management of severe cases. The treating surgeon must choose the surgical procedures in a pragmatic way.

Rhinocerebral zygomycosis: an increasingly frequent challenge: update and favorable outcomes in two cases.

Zygomycosis or mucormycosis is an increasingly frequent life-threatening infection caused by opportunistic fungal organisms of the class Zygomycetes. The pathognomonic feature is the presence of invasive aseptate mycelia that are larger than other filamentous fungi with the hyphae exhibiting right angle and haphazard branching. Usually classified as rhinocerebral, disseminated, and cutaneous types, this classification serves as important predictor of pathogenesis and outcome. These occur mostly in immunosuppressed patients including individuals with diabetes (43% exhibit the rhino-cerebral form) and patients with organ transplants and hematologic malignancies. Without early aggressive treatment, the disease follows a dismal and fatal course. The prognosis has not shown any appreciable change in the past 40 years with a stagnant mortality rate of 44%. We present 2 cases of rhinocerebral zygomycosis (RCZ), in a 58-year-old male and a 63-year-old female; both were poorly controlled diabetic patients with maxillary lesions suggestive of osteomyelitis. The patients were leading a near normal life with minimal discomfort or signs and symptoms of underlying mycosis. Most of the health care professionals treating these patients often overlooked the disease or recommended inadequate therapy. Despite long delays and inadequate initial therapy these patients survived with little outward morbidity. The prognosis for this condition may therefore be considered less dire than previously thought.

Left hemisphere and male sex dominance of cerebral hemiatrophy (Dyke-Davidoff-Masson Syndrome).

Although radiological findings of cerebral hemiatrophy (Dyke-Davidoff-Masson Syndrome) are well known, there is no systematic study about the gender and the affected side in this syndrome. Brain images in 26 patients (mean aged 11) with cerebral hemiatrophy were retrospectively reviewed. Nineteen patients (73.5%) were male and seven patients (26.5%) were female. Left hemisphere involvement was seen in 18 patients (69.2%) and right hemisphere involvement was seen in eight patients (30.8%). We conclude that male gender and left side involvement are frequent in cerebral hemiatrophy disease.
