Excision of a Preauricular Cyst


Preauricular cysts are a subset of asymptomatic, dome-shaped lesions referred to as epidermoid cysts. Cysts vary in size and have the ability to grow in diameter over time. These cysts can occur anywhere on the body and usually contain keratin. Upon examination of a suspected cyst, different characteristics can specify its type. Dermoid cysts are typically odorous lesions found around the eyes or on the base of the nose. If the cyst did not originate from sebaceous glands, it is not deemed a sebaceous cyst. Typically, surgical intervention is required to fully remove the cyst and prevent further infections or growth.


The video shows an 18-year-old female who presented with a preauricular cyst near her left ear. Upon history and physical examination, the mass was predicted to be a dermoid cyst rather than a sebaceous cyst. Surgical recommendations were given to perform an excisional biopsy of the cyst. The excision is displayed step-wise in the video.


A 2 cm incision was made just posterior to the lesion with a 15 blade scalpel. Dissection was carried with a sharp hemostat down the level of the parotid fascia. A 1 cm cystic structure was found adherent to the overlying dermis. An elliptical incision was then made over the mass and it was removed with the adherent overlying skin. The wound was then irrigated. Wound was closed in 3 layers. First, the deep layer was closed with 5-0 PDS in interrupted fashion, followed by 5-0 monocryl in running subcuticular fashion, followed by Dermabond


The patient was returned to the care of anesthesia where she was awoken, extubated, and transported to PACU in stable condition. The patient tolerated the procedure well and was discharged the same day.

The specimen was sent for pathological analysis. The pathology report showed that the mass was an epidermal inclusion cyst.

Sphenopalatine Artery Ligation

A 70-year-old male presented with persistent left-sided epistaxis, occurring 4 – 12 times a day for 3 weeks. Episodes lasted 10 – 15 minutes, but once required nasal packing at the ED.

Introduction: Ligation of the sphenopalatine artery is often indicated for patients with persistent posterior epistaxis that cannot be attributed to other causes. This video demonstrates a step-wise endoscopic sphenopalatine artery ligation using hemoclips.

Methods: In order to access the maxillary sinus cavity, a ball-tip probe was used to fracture the uncinate and a backbiter was used to remove the uncinate in its entirety. Once in the maxillary sinus, a backbiter was used to remove the tissue anterior to the normal ostium. A straight Tru-Cut was used to remove tissue posterior the natural ostium, taking down the posterior fontanelle. After this was done, a down-biter and a microdebrider blade were used to remove tissue inferior to the natural ostium towards the inferior turbinate. A caudal instrument was used to raise a subperiosteal flap just posterior to the left maxillary sinus posterior wall. Next, dissection from the inferior turbinate up to the top of the maxillary sinus was done from an inferior to superior direction, roughly 1 cm posterior to the posterior wall of the maxillary sinus. The sphenopalatine artery was seen coming out of the sphenopalatine foramen and soft tissue was dissected off this artery. Two hemoclips were placed over the entire artery.

Results: The patient was sent to recovery in good condition and no adverse reactions were reported by the surgeon or patient.
