After informed consent was obtained the patient was brought to the operating room and placed in the supine position. The correct patient and procedure were identified and a Time Out was performed. After induction of general anesthesia, patient was intubated transnasally from right nostril. The table was turned to 90 degree and head was extended. 2% xylocaine with 1:100,00 epinephrine was injected over the left side of the maxillary gingivolabial sulcus.
Patient was prepped and draped in usual fashion.
Approximately 3 cm long incision was made along the mucogingival junction on the left side preserving the gingiva at the dental margin. This went from just to the right of the central incisor and over to the left molar. Supraperiosteal dissection was performed till the desired vestibular depth using predominantly a 15 blade. The periosteum was intentionally incised towards the height of the sulcus to promote attachment of the mucosa and maintain a deep sulcus with healing.
In the process of obtaining adequate release towards the intended sulcus depth, a connection to the nasal cavity was noted where the fistula was previously repaired. Tissue manipulation was done around the left nasal fistulous tract to allow for closure and it was then sutured with 5-0 vicryl in intermittent fashion.
Leak test performed showed no leak. Another suture in figure 8 fashion was then also applied over the closure to ensure no leak.
The free cut mucosal edge of the lip tissue was then sutured to the depth of the vestibular sulcus using interrupted 4-0 monocryl sutures. The remaining raw periosteal surface was covered with a 2×2 cm piece of Neox 1K membrane and was secured with intermittent sutures with 4-0 monocryl. Hemostasis was great throughout requiring very little cautery..
A periopak was created that was also mixed with doxycycline powder and applied over the surgical site. Mouth was closed to reshape the Coepack dressing to remove excess material and to prevent chipping off while eating.
Having tolerated the procedure well the patient was turned back over to anesthesia, awakened and transferred to the recovery room in stable condition.
Z-plasty allows broken-line closure, reorientation of the defect in the horizontal plane with re-creation of a cervicomental angle, and most importantly, a lengthening of the anterior neck skin that aids in preventing recurrent contracture. We present our experience managing a congenital cervical midline cleft in a 3-month-old patient and describe a simple technique for planning the ideal Z-plasty closure. No simple description for planning the ideal closure for this defect could be found in the otolaryngology literature.
Background
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.
Introduction
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.
Methods
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
Results
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.
