Background
Parotidectomy is the treatment of choice in many parotid tumors. Due to the extensive nature of the procedure, unfavorable complications such as gustatory sweating, surgical site depression are common. Various techniques using fascia, muscle or AlloDerm have been developed but debate still remains regarding its availability and affordability. We applied a newly developed acellular dermal matrix (Insuregraf) to the parotidectomy field to act as a physical barrier and to provide adequate filling effect for prevention of functional and aesthetic complications.
Methods
From March 2010 to March 2017, 30 patients with parotid tumors underwent superficial parotidectomy. Twenty patients underwent only superficial parotidectomy. Ten patients had Insuregraf applied to the surgical site after superficial parotidectomy. We evaluated the incidence of Frey’s syndrome, surgical site depression, and patient satisfaction rate in both groups.
Results
The incidence of Frey’s syndrome was lower in the Insuregraf group (0 vs. 2). Surgical site depression was also lower in the Insuregraf group (2 vs. 20). Satisfaction score for facial contour in Insuregraf group was 9.2 out of 10, which was comparable to 6.2 out of 10 in the control group.
Conclusion
Application of Insuregraf after superficial parotidectomy is an effective surgical procedure to prevent complications such as Frey’s syndrome and surgical site depression. This technique is affordable and safe with no immune reactions. Above all this surgical method should be considered as an option for patients who are concerned about the contour of the face after surgery.
Skin and soft tissue defects in the lumbosacral area are commonly encountered in the field of reconstructive surgery, and it is well documented that the superior gluteal artery perforator (SGAP) flap provides excellent coverage of these defects. In this article, we describe our experience using a modified version of the SGAP propeller flap, in which the distal redundant portion of an elevated SGAP flap is deepithelialized, thereby maximizing the effect of the soft tissue augmentation. Thirteen patients with lumbosacral soft tissue defects treated between May 2010 and June 2012 were included in this study. The wound causes were pressure ulcer (n = 9), pseudomeningocele (n = 2), and hardware exposure (n = 2). In all patients, an elevated SGAP flap was rotated 180 degrees over the defect area and the extra distal portion of the flap was deepithelialized and used as a soft tissue filler or tamponade. During the follow-up period (mean, 26 months), 12 of 13 flaps survived completely. One flap was totally necrosed due to progressive venous congestion and was reconstructed with local advancement flaps. No further complications were noted. Because of the redundancy and pliability of the tissue in the gluteal area, a flap relatively wider or longer than the defect can be elevated safely. Hence, the redundant tissue volume can be tucked inside to facilitate soft tissue augmentation of the area. We propose that the deepithelialized version of the SGAP propeller flap is an effective option for the reconstruction of various lumbosacral soft tissue defects because it offers thick and healthy soft tissue from a distant site to the defect areas.
