reconstructive ideals of the phallus. The purpose of this study was to determine the preferred aesthetics of
phalloplasties.

Methods: Phalloplasty aesthetic subunits were defined, and subunit measurements and ratios were examined.
A split-testing questionnaire was distributed to medical personnel and online forum users to determine the
preferred aesthetic ideals based on phallic subunits. Digitally altered photos focusing on varying ratios of the
shaft, glans, corona, and frenulum were presented to participants who were instructed to choose the image
that was most aesthetically pleasing. Respondent demographics were collected, including age, sex, medical
background, and sexual orientation.

Results: One hundred thirty-nine people completed the survey. The overall preferred aesthetic ratios are
as follows: 74.8% (n = 104) preferred a corona length to width ratio of 20:1, 95.7% (n = 133) preferred a shaft
length to width ratio of 2.5:1, 51.1% (n = 71) preferred a unilateral taper to the glans, 79.9% (n = 111) preferred
no degree of shaft angulation, 69.1% (n = 96) preferred a length to width ratio of 1:1, 56.1% (n = 78) preferred
angulation at the glans corona junction, 57.6% (n = 80) preferred a curved curvature to the corona, and 66.2%
(n = 92) preferred a straight frenulum.

Conclusion: The preferred aesthetics of the reconstructed phallus varies by individual; however, this study
can be a guide for both patients and reconstructive surgeons during surgical planning.

3. The impact of traumatic dog bite injuries necessitating surgical treatment in elderly

Aim: Traumatic dog bite injuries are a common reason for emergency department visits and hospital
admissions. Most literature targets dog bite injuries in pediatric patients, but minimal studies are dedicated
to the elderly. This study was designed to investigate the epidemiology and overall healthcare burden of dog
bites in the elderly population.

Methods: Data was obtained using the Nationwide Emergency Department Sample (NEDS) database.
Inclusion criteria included patients 65 years or older with ICD-9 E90.60=dog bite. Site of injury and cellulitis
incidence were obtained. Types of procedures were categorized into two groups: minor and major therapeutic.
Inpatient length of stay and total charges were also collected.

Results: A total of 318,161 dog bite ED visits were identified, of which 24,541 were 65 years and older. Over
95% of patients had only a single injury site, most commonly the upper extremity (72.5%). The incidence of
cellulitis was 7.9%. Admitted elderly patients often had subsequent therapeutic procedures (minor 40.9%,
major 26.3%, flap/graft 3.6%). Average inpatient length of stay was 4 days. The average total charge for ED
services only was $1094 per patient and combined ED and inpatient services was $24,551.

Conclusion: Dog bite-related injuries are a significant source of trauma presenting to ED and often requiring
surgical treatment and hospital admissions, especially in elderly. The impact of dog bite injuries poses a
substantial burden on public health both medically and financially. Increased vigilance in prevention of these
injuries and their associated complications is crucial to reduce overall morbidity and medical costs.
