Impact of extent of parotid resection on postoperative wound complications: A prospective study

Abstract

Less extensive parotid resection seems to be associated with a higher incidence of postoperative sialocele and salivary fistula, but is also associated with less postoperative facial nerve dysfunction.

Prevalence and risk factors of sialocele formation after partial superficial parotidectomy: A multi‐institutional analysis of 357 consecutive patients

“…Herbert and Morton reported an incidence rate of 19.6% among subjects who underwent heterogeneous types of surgery. In a prospective study of 66 consecutive parotidectomies with the aim of investigating postoperative wound complications, 16.7% developed a sialocele and 6.1% developed a salivary fistula . In the present study, an incidence rate of 6.4% for sialocele formation among 357 consecutive patents was noted.…”

“…Given the fact that a sialocele is a leakage of saliva from the remaining gland parenchyma, partial superficial parotidectomy shows a higher incidence of sialocele development compared to near‐total or total parotidectomy. Tuckett et al also found less extensive parotid surgery to be associated with a high incidence of sialocele or salivary fistula formation. However, another study found that salivary fistula development was not associated with the extent of surgery .…”

Factors influencing sialocele or salivary fistula formation postparotidectomy

“…The rate of malignancy was lower in the sialocele group, but this was not statistically significant. As described by Witt and Tuckett et al, we might expect an increased risk of sialocele formation with a lesser degree of dissection (ie, as is commonly done for benign tumors). Our study demonstrated an absolute difference in the volume of tissue removed for patients with benign versus malignant disease who ultimately developed sialocele/salivary fistula; however, this difference was not statistically significant, indicating that volume of dissection may not differ based on pathology in patients with sialocele.…”

“…Currently, there is disagreement in the literature about the relationship between the extent of parotidectomy and subsequent sialocele formation. Witt and Tuckett et al concluded that the greater the extent of resection, the less likely sialocele formation will occur because there is less tissue available to create saliva. Conversely, Koch et al and Herbert and Morton did not find extent of dissection to be associated with sialocele formation.…”

The use of botulinum toxin B in the treatment of a post-traumatic sialocele in a 4-year-old child: A case report

“…Sialoceles are known complications of superficial parotidectomy in adults, with reports of incidence in the literature ranging from 6-39% [7][8][9][10] . Penetrating injury to the parotid gland is another common etiology of sialocele, either from direct trauma to the parotid duct or the gland itself.…”
