Congenital Cyst and Fistula of the Dorsum of the Nose: A Case Report and Literature Review

Congenital cyst and fistula of the dorsum of the nose is a rare congenital entity. We report a new case of dorsum nasal fistula in a 5 years old male patient that communicates the frontal region with the subcutaneous surface. Radiologic imaging showed a median 5mm defect, in the projection of the metopic suture that leads to a communication between the frontal region and the skin figure. Complete resection was performed by an external approach with vertical incision of the cyst. The histological diagnosis was consistent with a dermoid fistulized cyst. The follow-up displayed unremarkable finding, the patient did not present any diplopia nor decreased visual acuity, or any signs of meningitis or cerebrospinal fluid rhinorrhoea, or saddle nose.

A. Mueller (Victoria in Australia). - Two Curiosities in Midwifery practice. (Australasian Medical Gaz., 1894, VIII, p. 258). Two rare cases in obstetric practice

1) Congenital cyst, emanating from the spine, as an obstacle to childbirth. In 30-year-olds, I-women in labor, the baby's head sank into the pelvic cavity, the cervix opened, but despite the good contractions, labor was delayed. Examining the pelvis of a woman in labor with his finger to find out the reason for stopping labor, Mueller felt a fluctuating tumor in the lower part of the sacral cavity, the size of a hen's egg. Dr. M .. checked the result of examination of the per rectum and found it more convenient to pierce the tumor with a test trocar from the rectum. In the fluid released from the tumor, the light, straw color turned out to be epithelial, cylindrical cells, indicating that the cyst was congenital (Eulenburg) and communicated with the cavity of the fetal spine. Childbirth ended with forceps, with great effort in the course of half an hour. The postpartum period went well.

CLINICAL CHARACTERISTICS, RESULTS OF SURGICAL TREATMENT IN CONGENITAL CYST AND FISTULAS OF THE OTORHINOLARYNGOLOGY

Background: To study the clinical characteristics, results of surgical treatment in congenital cyst and fistulas of the otorhinolaryngology. Patients: 74 patients diagnosed congenital cyst and fistulas of the otorhinolaryngology was treated with surgery, from May 2016 to June 2017 at Hue University Hospital, Hue Central Hospital and Da Nang Hospital for women and children. Main outcome measure: diagnosis, the clinical and pathologic features, the method and the results of surgical treatment. Results: We identified 74 patients, 83.8% of them had the preauricular fistula, 9.5% had thyroglossal fistula, 4.1% had type II branchial cleft cyst, 1.4% had type I branchial cleft cyst and 1.4% had pyriform sinus fistula. The pathologic feature: inflammation, abscess accounted for 52.7%, normal accounted for 47.3%. Complications after surgery: 1.4% of mild complications are hematoma and 1.4% of infection after surgery, without neurological complications. Recurrence after surgery: 1.4%. Conclusions: In all types of congenital cyst and fistulas of the otorhinolaryngology, preauricular fistula is the highest, the most common form of injury is inflammation, abscesses. Complications after surgery are mild, without neurological complications. Key words: cyst, fistula, congenital, results of surgical treatment
