Abstract
Condylar fracture treatment is a debated topic among maxillofacial surgeons. Various surgical techniques are used today, each one with advantages and disadvantages. The aim of this study is to present and evaluate our technique adopted for treatment of any type of extracapsular condylar fractures. Between 2020 and 2022, 16 condylar fractures were treated. In two patients with bilateral condylar fractures, the present technique was compared to the mini-retromandibular approach. All the patients were checked for clinical and radiological outcomes, facial nerve injury, scar visibility and presence of salivary complications. Dental occlusion was always restored, and facial nerve damage or salivary disorders were not observed. The skin incision, limited to the caudal two-thirds of the auricle, made the scar almost invisible and greatly improved the surgical field in the condylar neck area, facilitating the treatment. The proposed technique provides easier internal fixation for both neck and base condylar fractures with good cosmetic results, ensuring better protection of the facial nerve and parotid gland. The surgical technique described has not shown disadvantages in terms of operational difficulty, results, and complications. This novel surgical technique could represent a new choice in the treatment of extracapsular condylar fractures, although further studies are needed to support this new proposal.

Abstract
Introduction The oral cavity is a rare site for other organs' tumor metastases. The incidence rate ranges from 1% to 3% of all oral malignancies. Metastases more frequently localize in the mandible, especially in the molar area. Metastases within odontogenic cysts are extremely rare, thus in the literature, only a few cases have been reported. The follicular cyst is one of the most frequent cysts of the jaws. Radiologically it shows as a unilocular lesion with a sclerotic border, characterized by a homogenous radiolucency that incorporates the crown of the unerupted tooth. Methods A 76-year-old female patient, affected by stage IV of lung adenocarcinoma, reported pain on the left mandible border, alongside lip dysesthesia. The ortho-panoramic radiograph showed a follicular cyst in the posterior left side of the mandible, with involvement of the ascending branch region. The cyst was surgically removed together with the impacted tooth. A histopathological examination of the specimen confirmed the diagnostic suspect of a follicular cyst, but in the cystic wall, focal infiltration of epithelial neoplastic cells was also found. The immunohistochemical analysis showed the presence of three different markers: CK 7+, TTF1+/-, and P40-. These markers identify the cells as metastatic lung carcinoma. Results Secondary tumor spreading in the jaws' area is rare (3% of all malignant lesions). Despite odontogenic cysts can undergo a dysplastic transformation (affecting the epithelial covering in ≤1% of the cases), infrequently these neoplastic cells can be related to secondary tumor spreading in a cystic wall. This report describes a metastatic localization within a mandibular follicular cyst. Conclusions Malignant cancers' metastasis in the oral district remains a rare and unexplored condition, especially when metastases are located in odontogenic cysts. In this circumstance, surgical removal and histopathological examination are strongly recommended.

Abstract
Epidermoid cysts are benign slow-growing developmental lesions resulting from ectodermal tissue that can localise anywhere in the body. Only 7% of all epidermoid cysts are located in the head and neck area and, together with dermoid cysts, account for less than 0.01% of all oral cavity cysts. Herein, we present the case of a 17-year-old male diagnosed with a sublingual epidermoid cyst and a review of the literature on this rare localisation, focusing on clinical and imaging features, management and outcomes. All the articles reporting epidermoid cysts located in oral cavity were searched using PubMed/Medline, discarding all those not located in head and neck district, not mentioning diagnostic imaging, not defined as epidermoid cysts by a histopathological diagnosis, and those for which only an abstract was available. In literature there were 35 articles, from 1993 to 2020, that meet the aforementioned requirements, for a total of 38 patients and 39 cysts. For each article, age, sex, onset time of symptoms, location, size and surgical access were analysed. Particular attention was paid to the radiological investigation used in order to understand the most common imaging aspects and also rare cases with unusual presentations.

Abstract
The survival of bacteria on dry swabs varied from twenty pro cent of organisms alive to no viability at four hours after the inoculation. Cotton-wool swabs highly reduced survival of bacteria; alginate or albumin swabs were less toxic for Gram-positive bacteria, charcoal swabs for Gram-negative bacteria. Transport systems allow certain organisms to remain viable as long as 24--48 hours. The quality and accuracy of any bacteriological culture depends greatly upon obtaining a proper specimen. Cotton-wool swabs are to be employed only when cultures are made immediately after collection, dry swabs--charcoal, albumin coated or calcium alginate--when cultures are made within four hours. For longer periods of time only transport systems are to be employed.
