"Pot-lid" technique for aesthetic removal of small lipoma on the face

C-punch excision: a novel technique

A conventional skin punch biopsy instrument has a circular hollow blade, which can be used to make a full circular incision to evacuate subcutaneous abnormalities such as lipomas. Here, we present a modified punch instrument, in which the cutting element has a C-shape to form a pivotal skin fragment (miniflap) to access subcutaneous tissues. The "C" part comprises almost half of a circle. The C-punch incision gives access to subcutaneous abnormalities, while keeping a connecting neck to the surrounding skin, which allows for efficient resealing of the skin surface. Therefore, there is less potential for subsequent scarring.

Novel uses of skin biopsy punches in dermatosurgery

The skin punch or surgical punch is an instrument which is used almost exclusively by dermatologists. It is a circular hollow blade attached to a pencil-like handle ranging in size from 0.5 to 10 mm. It is available as a disposable, reusable, and automated instrument. The punch can be used as a diagnostic, therapeutic, and cosmetic tool in dermatology. We have used punch as a diagnostic, therapeutic, and cosmetic tool in our dermatosurgery practice in our hospital. Various original research articles, text book publications, and review articles were studied and compiled. Techniques used by various authors and our own experiences with punch have been described. This article aims at providing the novel usefulness of skin biopsy punch in dermatology as the basic punch surgery is quick and easy to learn. Complications such as bleeding and infection are minimal.

Versatile punch surgery

BACKGROUND

Punch instrument is a circular blade that can be used for many diagnostic and therapeutic purposes in different medical and surgical specialties. Punch surgery (or biopsy) is achieved by using this versatile punch blade under local anesthesia. Basic punch surgery is quick and easy to learn. Complications such as bleeding and infection are minimal. Diagnostic punch surgery can obtain a part of or whole skin lesion for histologic examination. In addition to the skin, nail and mucous membrane tissue can be obtained by punch biopsy. Interestingly, punch biopsy can be used as an adjunctive to fine-needle aspiration to establish the diagnosis of tumors of solid organ such as the breast. Diagnostic punch surgery can be modified to overcome certain problems. The split-punch technique helps avoid crushing the tissue punch when trying to divide it for different examinations. The double-trephine punch facilitates obtaining subcutaneous tissue without the need for full elliptical excision. The string-of-beads technique obviates the need for dissection of tissue into pieces. In other nondermatology and dermatology conditions, such as nerve pathology, arteriosclerosis, melanoma mapping, and eyelid tumors, the diagnosis can be enhanced with the use of punch surgery.Therapeutic punch surgery can be used for excision of unwanted lesions such as nevi, as well as pathologic bone and cartilage tissues. Punch grafting is used in vitiligo surgery and hair transplantion. Punch evacuative surgery can help in the evacuation of unwanted tissue or materials such as lipoma, subungual hematoma, scrotal calcinosis, pseudocyst of the auricle, pilar cyst, and others.Reconstructive punch surgery includes correction of ear lobe defects and acne scars. Enhancement of wound healing can be achieved by use of the punch; therefore, it can help nonhealing ulcers.

Excision of subcutaneous facial cysts and lipomas using cosmetic approaches

PURPOSE

The excisional biopsy of subcutaneoous facial cysts and lipomas can be problematic due to the high esthetic nature of the affected area. Remote scar placement has advantages in allowing access to subcutaneous pathology while placing incision lines in cosmetic locations. This article will review excisional biopsies of subcutaneous facial cysts and lipomas using cosmetic approaches.

PATIENTS AND METHODS

Patients with superficial facial cysts or lipomas undergoing excisional biopsies utilizing contemporary cosmetic surgery approaches (rhytidectomy, lower blepharoplasty, and submental) with tumescent anesthesia and either intravenous sedation or general anesthesia.

RESULTS

All patients had successful removal of superficial facial pathology with good cosmetic results.

CONCLUSION

The use of contemporary cosmetic surgical approaches for the excisional biopsy of superficial facial cysts and lipomas provides adequate surgical access, a cosmetically acceptable result, and is well-tolerated by patients.
