Background Endoscopic excision of forehead lipoma is
increasingly utilized for its inconspicuous scarring, good
intraoperative visualization and low complication rates.
Currently, studies comparing outcomes from endoscopic
and open excision of forehead lipomas are lacking. This
retrospective study compares the surgical outcomes of the
Methods The authors retrospectively reviewed medical re-
cords of all patients who had undergone forehead lipoma
excision at a single institution between 2010 and 2015.
Data collected included patient demographics, lesion size,
mean operative time and postoperative complications. A
comparison was made between the two groups of patients.
Results Sixty-two patients underwent excision of their
forehead lipoma (38 endoscopic and 24 open excisions).
Patient groups were similar in terms of sex ratios, size of
lesion, choice of anaesthesia, mean operative time and
duration of follow-up. Swelling beyond 1 week in the
endoscopic group was 1/38 (2.6 %) compared to 4/24
(16.7 %) in the open excision group (p = 0.07).
Postoperative scalp numbness in the endoscopic group
group (p = 0.64). Incidence of haematoma in the endo-
in the open excision group (p =1).All38patientsinthe
endoscopic group were satisfied with their scars compared
with 4/24 (16.7 %) in the open excision group who re-
ported dissatisfaction (p =0.02).
Conclusions Complication rates of both surgical techniques
are similar. Given that the endoscopic technique results in
cosmetically superior outcomes, with no increase in morbidi-
ty, the authors recommend the use of endoscopic technique for
forehead lipoma excision.
Level of Evidence: Level III, therapeutic study.
Forehead lipomas are often a cause of cosmetic concern for
patients. Traditionally, excision of forehead lipomas involved
use of direct incisions over the forehead which results in un-
aesthetic forehead scars [1–3]. The use of endoscopic tech-
niques in plastic surgery is becoming commonplace [3, 4].
In cases of forehead lipoma excision, endoscopic excision
allows remote location of incisions in inconspicuous sites,
good visualization of the operative field, low complication
rates and earlier return to work [3–6].
Although the benefits of endoscopic excision of forehead
lipoma have been described, currently, there are no studies
comparing the safety and efficacy of forehead lipoma excision
using the endoscopic technique versus open excision. The
authors conducted a study aimed at comparing the surgical
outcomes of the two techniques in the removal of forehead
