Retroauricular hairline approach versus conventional approach for
submandibular gland resection: a meta-analysis
Abstract
Background and Objectives: The retroauricular hairline approach
is increasingly being used for submandibular gland resections because of
the excellent cosmetic results. A meta-analysis of studies compared the
retroauricular hairline and conventional approaches for submandibular
gland excision. Methods: A meta-analysis of studies identified
from the PubMed, Embase, and China National Knowledge Infrastructure
databases was performed. Postoperative nerve damage (temporary earlobe
numbness and other signs of nerve damage), surgical durations, wound
lengths, intraoperative bleeding volumes, postoperative drainage, and
lengths of hospital stay were compared. Results: The
retroauricular hairline approach led to greater risk of temporary
earlobe numbness (OR: 7.28; 95% CI: 1.57–33.87; P = 0.01), but this
resolved during the follow-up. There was no significant difference in
the risk of other nerve injuries between the two approaches. The
retroauricular hairline group had significantly longer operative times
and wound lengths compared to the conventional resection group. There
were no significant differences between the two approaches in
intraoperative bleeding volumes, postoperative drainage, and lengths of
hospital stay. Conclusions: The retroauricular hairline
approach is a safe and efficient alternative to the conventional
approach. It provides better cosmetic results and does not increase the
risk of long-term neurological complications.
