OBJECTIVE
Dermoid is a rare disease located in the head and neck and only sporadic cases were previously reported. Surgery with different operational paths is the best solution to the disease. We aimed to analyze the clinical characteristics and outcomes of surgical approach for treating dermoid originated from the middle ear and Eustachian tube.
METHODS
In this retrospective case series, four cases of dermoids of the middle ear and Eustachian tube, treated by endoscopic-assisted surgical approach were reviewed and analyzed.
RESULTS
Patients' ages ranged from 7 months to 16 years. All cases involved the middle ear, eustachian tube, and the parapharyngeal space. Postoperative follow-up ranged from 6 months to 11 years. No facial nerve paralysis was observed during or after surgeries. Treatment was efficient in the four cases, with no residual symptoms during post-operative follow-up.
CONCLUSIONS
Dermoid of the middle ear involving the eustachian tube usually appears in children of early age. Surgical resection with assistance of endoscope has satisfying outcome for these cases.

Review
OBJECTIVE
The study aimed to present the accuracy of radiological diagnostics in pediatric patients with nasal dermoids and to discuss the potential factors influencing the radiological pitfalls on imaging in these cases.
MATERIAL AND METHODS
The patient's cohort included 25 surgically treated pediatric cases with nasal dermoid. The results of preoperative imaging studies were analyzed regarding intraoperative findings. A review of the literature concerning a series of cases with nasal dermoid was performed in order to evaluate the possible radiological pitfalls and the accuracy of radiological imaging. The following statistical parameters for the particular radiological tools was determined: sensitivity, specificity, predictive positive values and predictive negative values.
RESULTS
Total number of 18 CT and 14 MRI were performed. 6 out of 32 radiological examinations occurred to be inconsistent with operative findings. Potential pitfalls were identified and discussed. All the patients with false radiological results were below the age of 5 and 83% were below the age of 3 y.o. The overall sensitivity (S), specificity (SP), predictive positive value (PPV) and predictive negative value (PNV) for CT vs. MRI were 68% vs. 79%, 90% vs. 95%, 65% vs. 86% and 90% vs. 92%, respectively.
CONCLUSIONS
MRI technique characterizes with higher predictive values in terms of identifying intracranial extension of nasal dermoid on imaging. Further analysis of radiological methods' accuracy should be conducted based on the detailed data concerning age distribution. The combination of CT and MRI should become a gold standard in diagnostics of nasal dermoids in children under the age of 5.

Comparative Study
INTRODUCTION
Dermoid cysts are common, benign, embryologically derived soft tissue cysts that can arise at a variety of craniofacial sites. It is not known whether specific histological variations exist between the different craniofacial sites. This study aims to establish whether inter-site histologic differences exist between periorbital, nasal, scalp, and postauricular dermoid cysts and analyze these in context of their distinct embryological origin and varied clinical presentation.
METHODS
A retrospective review of craniofacial dermoid cysts was performed. Using light microscopy with hematoxylin and eosin staining, histological appearance was directly compared between craniofacial sites.
RESULTS
All (n = 16) cysts contained keratinizing, stratified squamous epithelial lining, intraluminal keratin, and hair. Sebaceous glands were commonly present (n = 13). Eccrine (sweat) glands were less common (n = 3). Structures of mesodermal origin were seen in three periorbital cysts. Only the six ruptured cysts showed evidence of inflammation.
CONCLUSIONS
Histological properties of dermoid cysts are conserved between craniofacial sites (periorbital, nasal, scalp, and postauricular). This reflects the consistency of ectodermal inclusion during early embryological development, which is independent of specific craniofacial site or surrounding anatomical structures.

This study aimed to evaluate the effect of within-endobag cystectomy during and after laparoscopic ovarian cystectomy in patients with dermoid cysts. We retrospectively analyzed 84 patients with ovarian dermoid cysts who underwent laparoscopic ovarian cystectomy. In 30 patients, the affected ovary was placed in an endobag before cystectomy and cystectomy was performed within an endobag (within-endobag group), while the remaining 54 patients underwent standard cystectomy without this step (without-endobag group). After cystectomy, the cyst wall was placed in an endobag and was removed from the abdomen. Compared with the without-endobag group, the within-endobag group had a significantly lower rate of cyst content spillage (23.3% vs 72.2%, P < .001) and significantly shorter operation times when the cysts ruptured (23.4 ± 8.6 minutes vs 51.2 ± 28.6 minutes, P < .001). Whereas there was no significant difference in operation time in the absence of cyst rupture between 2 groups (21.2 ± 8.8 minutes vs 31.1 ± 17.4 minutes, P = .111). In patients with cyst rupture, according to the cyst size increase, the operation time was significantly prolonged without-endobag, whereas no significant prolongation was observed in within-endobag cystectomy. Except for operation time, there were no significant differences in cyst length, pain on the first day after surgery, hemoglobin loss, hospital stay, and inflammatory markers (C-reactive protein and white blood cell counts) in both ruptured and unruptured cases between the 2 groups. There were no postoperative complications in the within-endobag group, but 2 cases of perioperative complications occurred in the without-endobag group. No chemical peritonitis due to spillage of the cyst contents was observed in either group. Laparoscopic ovarian cystectomy performed within-endobag can reduce both the spillage rate of cyst contents and operation time regardless of cyst size in patients with ruptured cysts. Therefore, this technique is a good surgical option for the laparoscopic ovarian cystectomy of large dermoid ovarian cysts.

Of ectopic pregnancies encountered in clinical practice, more than 95% are located within the fallopian tube, and 2% to 4% are cornual. A cornual ectopic pregnancy is a serious clinical condition and poses diagnostic and therapeutic challenges. Thus, understanding the clinical course and treatment options is essential. The authors describe the case of a 29-year-old woman who presented to the Department of Obstetrics and Gynecology. The patient was suspected of having a cornual pregnancy, and a dermoid cyst had been detected during routine ultrasonography. In the absence of maternal symptoms, the clinical scenario is potentially dangerous and must be treated promptly and efficiently to decrease morbidity and mortality.

Dermoid cysts are one of the most common benign orbital tumours in children and usually occur unilaterally. Bilateral dermoid cysts in the orbit are rare. We report here, a case of bilateral orbital dermoid cysts, in a 29-month-old baby girl. The patient's prognosis was favourable following surgical resection. Through this case report, we hope to increase the recognition and understanding of this condition.

Review
The Klippel-Feil syndrome (KFS) has been reported to be associated with intracranial neoplasms, most frequently epidermoid or dermoid cysts. To our knowledge, however, patients who present with a posterior fossa dermoid cyst (DC) and KFS are extremely rare with only 24 previously reported cases in the English literature worldwide. Therefore, we present the first report of a patient with a craniocervical ruptured DC accompanied by craniovertebral junction (CVJ) anomalies, KFS and mirror movement. Meanwhile, a literature review of KFS accompanying with posterior fossa DC discusses these conditions from the embryological, anatomical, clinical and therapeutic perspectives. Additionally, the combination of CVJ anomalies, KFS and DC may represent a new syndrome that has previously gone unnoticed.

Review
Congenital midline nasal masses are rare. Nasal dermoid sinus cysts(NDSC) are the most common type of the congenital midline nasal masses in childhood. Clinical manifestations are midline nasal cysts, fistula and intracranial attachments. Nasal encephalocele and glioma should be included in the differential diagnosis. Radiologic images are instructive. NDSC are easily misdiagnosed, leading to recurrence and surgical trauma affecting the face. Early appropriate surgical excision is recommended. This article reviews the embryology pathogenesis, progress of diagnosis and treatment of congenital NDSC.
