BackgroundDermoid cysts are congenital tumors that are benign. Dermoid cysts with intracranial extension can cause serious neurological complications. It is important, therefore, to determine whether a patient has a dermoid cyst when their chief concern at a doctor’s visit is a mass in the head or neck area. In this study, we present a literature review of dermoid cysts and an analysis of the authors’ experiences, with the goal of providing guidance useful for the diagnosis and treatment of dermoid cysts.MethodsThis study retrospectively analyzed the medical records of 62 patients who visited the two medical clinics with which the authors are affiliated. The patients were enrolled between October 2003 and January 2017.ResultsOf the 62 patients analyzed in this study, 32 were 0 to 5 years of age (52%) and 23 were 17 years of age or older (37%). Forty-seven patients underwent 1 or more imaging study during the process of diagnosis. Thirty-two patients were suspected to have a dermoid cyst. Forty-nine patients were analyzed to determine the depth of the cyst. Bone was seen in 43 patients through imaging tests or during actual surgery, and nine of the 43 had bony problems (21%).ConclusionsThis study found that dermoid cysts were present in many adults, and that a high rate of deep lesions was observed, as well as many cases in which even the bone was affected. These results suggest, therefore, that dermoid cysts should be considered, and medical professionals should actively conduct imaging studies.
Intraosseous hemangioma is an extremely rare tumor that accounts for 1% or fewer of all osseous tumors. The most common sites of its occurrence are the vertebral column and calvaria. Occurrence in a facial bone is very rare. The authors aim to report a case of the surgical treatment of intraosseous hemangioma occurring in the periorbital region, which is a very rare site of occurrence and to introduce our own experiences with the diagnosis and treatment of this condition along with a literature review. A 73-year-old male patient visited our hospital with the chief complaint of a mass touching the left orbital rim. A biopsy was performed by applying a direct incision after local anesthesia. Eventually, intraosseous hemangioma was diagnosed histologically. To fully resect the mass, the orbital floor and zygoma were exposed through a subciliary incision under general anesthesia, and then the tumor was completely eliminated. Bony defect was reconstructed by performing a seventh rib bone graft. Follow-up observation has so far been conducted for 10 months after surgery without recurrence or symptoms.
In many patients, the volume of the upper lip is deficient after cleft lip repair operation. However, there is no well-established procedure to correct this volume deficiency. In the present study, the authors attempted to increase the overall three-dimensional volume of the upper lip in repaired cleft lip patients with upper lip volume deficiency through autogenous microfat grafting. Thirty patients with upper lip volume deficiency after cleft lip repair underwent fat grafting in the upper lip from November 2007 to March 2015. Among these patients, postoperative outcome was evaluated in 15 patients using 2 methods for the evaluation. One method involved measuring the change in the shape of lips using pre- and postoperative photographs, and the other involved investigating the levels of satisfaction with the surgical results by distributing a scoring questionnaire to patients, doctors, and the general public. The ratio of upper lip protrusion relative to the lower lip increased by 46.71% on average after operation, and the sum of the vermilion heights increased by 31.68% on average. In the survey of satisfaction levels, patients, plastic surgeons, and the general public gave mean scores of 3.80, 3.91, and 4.03, respectively. When volume deficiency of the upper lip is present in repaired cleft lip patients, correction using autogenous microfat grafting is believed to be effective.
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.
