The use of smartphones for intra-operative photography - how we do it

The iPhone, the reflex, and the vinyl record: is the smartphone taking the best intraoperative photographs?

Surgical field photography is a tough exercise: surgeons dedicate the required time for photography even during complex surgeries; the intense lighting of the operating field works against photography, and the surgeon has to utilise whatever equipment is available. We selected five complex interventions and two surgeons (one with an iPhone^® and one with a Digital Single Lens Reflex [DSLR] camera) who each took a photograph of the operating field. The source of photographs was blinded, and the image quality was scored using a 5-point Likert scale by three groups of team members with differing experiences: six senior surgeons, two junior surgeons, and four surgical residents. We evaluated the resolution (adequate for clinical interpretation), colour (appear true and natural), contrast (adequate to distinguish different structures), and overall quality. The mean ± SEM overall image quality was similar for both the smartphone and DSLR (3.7 ± 0.1 vs. 3.8 ± 0.11; p = 0.87), as were most of the scores for each image characteristic. Surgeons seek objectivity and efficiency. The smartphone is a more convenient photographic equipment and produces identical results than the DSLR. Human beings can be sensitive to image quality. The DSLR image was found to be sharper, however, this was found to be imperceptible.

Association of Autologous Costal Cartilage Harvesting Technique With Donor-Site Pain in Patients Undergoing Rhinoplasty

Importance

Postoperative pain at the donor site is a common morbidity following autologous costal cartilage grafting.

Objective

To evaluate postoperative pain at the donor site after the use of a muscle-sparing costal cartilage harvesting technique compared with a muscle-cutting technique using electrocautery.

Design, Setting, and Participants

Designed as a controlled trial without randomization, this prospective, comparative cohort study was conducted between January 1, 2016, and March 31, 2017. Participants included 20 patients who underwent rhinoplasty for various cosmetic and functional complaints from January 1, 2016, to February 28, 2017. Of the 20 patients, 1 was excluded owing to an infection that developed on postoperative day (POD) 7. Patients were grouped by the rib harvesting technique used that was either a muscle-sparing technique (n = 11) or a muscle-cutting technique (n = 8). Skin incisions for both groups were carried out with a blade. Transection of muscle fascia and muscle fibers was performed with monopolar electrocautery in the muscle-cutting technique group. Blunt dissection with a hemostat was performed in the muscle-sparing technique group. All other surgical techniques were identical.

Main Outcomes and Measures

Postoperative pain was assessed with visual analog scale scores for resting pain and movement pain. Eight pain measurements were noted at the sixth postoperative hour and on PODs 1, 2, 3, 7, 15, 30, and 45. During the hospital stay, the postoperative need for analgesics was recorded daily as the number of analgesic infusion vials used.

Results

The 19 patients in the study included 11 women and 8 men whose mean age (SD) was 33.2 (10.3) years The mean (SD) visual pain analog scale scores for resting pain and movement pain were consistently higher in the muscle-cutting technique group than in the muscle-sparing technique group. This difference was statistically significant on PODs 2, 3, and 15 for resting pain and on PODs 2, 3, 7, 15, 30, and 45 for movement pain. The mean postoperative need for analgesic infusion vials during hospital stay was higher in the muscle-cutting technique group, and the difference was statistically significant on POD 2 (1.9 [0.6] vials vs 1.0 [0.9] vials; P = .02).

Conclusions and Relevance

Both resting and movement pain at the donor site was significantly reduced in the muscle-sparing technique group during the postoperative period, findings that align with anecdotal reports in the literature. Routine use of the muscle-sparing technique in autologous costal cartilage harvesting is recommended to reduce postoperative pain.
