Back to basics: A case series of angular dermoid cyst excision

Objective Transoral surgery is becoming a preferred technique because it does not leave any scar after surgery. However, transoral surgery for a dermoid cyst of the oral cavity is not standardized yet, due to the anatomic complexity of this region. The aim of this study was to evaluate the safety and efficacy of a transoral dermoid cyst excision. Study Design Multicenter prospective observational study. Setting University hospital. Subjects and Methods This study was designed as a 4-year prospective multicenter evaluation of dermoid cyst excisions within the floor of mouth. Clinical outcomes and complications related to procedures were evaluated among patients. The primary outcome was the efficacy of the procedure, and the secondary outcome was cosmetic satisfaction of each procedure. Results Twenty-one patients underwent transoral dermoid cyst excisions, and 22 underwent transcervical excisions. In the transoral surgery group, the mean size of the dermoid cyst was 5.35 cm (95% CI, 4.79-5.91), and in the transcervical surgery group, it was 6.19 cm (95% CI, 5.67-6.71). There was no significant differences with respect to overall demographic characteristics between the groups. However, the duration of the operation was shorter with the transoral group than with the transcervical group ( P = .001), and cosmetic satisfaction was much better in the transoral group ( P < .001). Conclusion Transoral dermoid cyst excision is a potentially safe and effective method that can lead to easy and quick removal of an oral cavity dermoid cyst, with excellent cosmetic outcomes.

Background: Malignant transformation in a dermoid cyst of the ovary is a rare complication, occurring in only 1-2% of cases, with squamous cell carcinoma being the most common type. Preoperative diagnosis is difficult because of the lack of specific symptoms and signs to suggest malignancy. The prognosis is generally poor when disease has spread beyond the ovary. Objective: This study was conducted to review experience with this disease and describe the current treatment modality. Methods: It was identified 4 women with this diagnosis during 2013-2018. This is a descriptive study, looking at the patient’s characteristics, mode of presentation, the role of tumor markers and radiological imaging in diagnosis. It was also examined the stage and pathological features of the presentation and subsequent course of the disease. Result: The median age was 45 (range: 32-63 yrs). Three cases were stage I and one case was stage III. The average tumor diameter was 14.1cm. All patients were under surgery. Two patients not received any adjuvant therapy and two patients received adjuvant chemotherapy. One patient had recurrent disease in the pelvis during adjuvant chemotherapy and died at 8 month of her diagnosis. Other three patients were disease free for last 3 years. The overall 2 yrs survival was 70%. Conclusion: Squamous carcinomas arising in mature cystic teratomas are commonly large ovarian tumors that occur in perimenopausal women often present as an incidental finding. There are no reliable diagnostic tools or prognostic indicators. The behaviour of these tumors is unpredictable. Conservative surgery may be considered in women wishing to preserve fertility. The role of chemotherapy and radiotherapy remains unclear in the adjuvant or metastatic setting.

Coronal Incision

OBJECTIVEUp to 10% of midline nasal dermoid cysts have intracranial extension. Previous techniques of excision include frontal and frontonasal craniotomies via a coronal approach, combined with a direct cutaneous excision of the dermoid cyst. While the coronal incision allows for wide visualization, it carries significant risks of transfusion, blood loss, and scarring. The authors present an alternative technique in which access is gained through a midline extension of the dermoid cyst excision that provides direct access for a keyhole frontal craniotomy.METHODSThe authors utilize a nasal bone osteotomy, pericranial flap, and keyhole-type craniotomy performed through a nasal midline incision for the treatment of nasal dermoid cysts with intracranial extension. They performed a retrospective chart review of all patients with nasal dermoid cysts treated at the Ann & Robert H. Lurie Children’s Hospital of Chicago from 2009 to 2017. Patient demographic data, operative data, and in- and outpatient complication data were collected.RESULTSIn 10 patients with cyst extension near or into the intracranial cavity (7 with true intracranial extension), the nasal osteotomy technique was performed. The mean blood loss was 13 ml, with a 0% transfusion rate. The mean length of inpatient stay was 1 day. A durotomy was made and repaired as part of the dermoid cyst dissection in 3 patients. One patient underwent intraoperative placement of a lumbar drain. The mean operative time was 228 minutes. There were no intraoperative or postoperative complications, including the need for a reoperation. No patients had any long-term complications, and no patients have had dermoid cyst recurrence. The appearance of the scar was acceptable in all cases.CONCLUSIONSThe midline approach to nasal dermoid cysts with intracranial extension is safe and results in limited blood loss, short operative times, and short lengths of inpatient hospital stay. This is a viable technique for the treatment of this challenging pathology.
