NECKLIFT GLAND RESECTION
Season 1, Episode 12
This new article from Dr. Shauly and his research team analyzes submandibular gland resection as a specialized technique for improving aesthetic neck contours during facial rejuvenation. While traditional neck lifts often fail to address deep structural fullness, these sources evaluate various surgical approaches ranging from standard transcervical excision to innovative robotic and endoscopic methods. The data suggests that partial gland reduction and energy-based tools significantly enhance patient satisfaction and cervical definition, and significantly reduce complications such as hematoma or nerve injury. Ultimately, the authors propose a standardized framework to guide surgeons in safely integrating these procedures into modern aesthetic practice.

Short Answer Key
Traditional platysmaplasty primarily addresses superficial tissues and may fail to correct deep-seated structural fullness. Hypertrophy or ptosis of the submandibular glands can persist despite these procedures, compromising the refined cervical silhouette.
Ligasure-assisted resection significantly reduces intraoperative bleeding and the risk of postoperative hematoma. It also helps maintain low complication rates and can decrease overall operative time during deep-plane neck lifts.
Retroauricular approaches have a significantly higher rate of marginal mandibular nerve injury (34.8%) compared to transcervical approaches (5.5%). However, retroauricular methods offer superior scar concealment, whereas transcervical methods result in visible cervical scarring.
The most significant complication is marginal mandibular nerve injury, occurring in nearly 10% of cases. Other notable complications include hematomas, sialoceles, infections, seromas, and visible scar formation.
Partial resection reduces the physical bulk of the gland to improve the aesthetic contour of the neck. By leaving a portion of the gland intact, surgeons aim to preserve salivary function and reduce the risk of symptomatic dry mouth.
These approaches are generally contraindicated in patients with malignancy, oral cavity infections, or a history of radiation to the area. Additionally, patients with limited mouth opening are not suitable candidates for transoral techniques.
A modern deep-plane approach can counterintuitively emphasize the submandibular gland by tightening surrounding tissues. This can result in more pronounced fullness if a hypertrophic gland is not addressed directly.
Endoscopic-assisted and intraoral/transoral techniques reported the lowest revision rates, ranging from 0% to 0.9%. Endoscopic cases also demonstrated expedited recovery times, averaging less than two weeks.
While the intraoral approach avoids external scars, it poses a risk of transient lingual nerve paresthesia and dysphagia. Furthermore, the non-sterile environment of the oral cavity increases the risk of postoperative infection.
The study concludes that submandibular gland resection is a safe and effective adjunct to aesthetic neck contouring when performed on properly selected patients. Complication rates are generally comparable to standard neck lifts performed without gland excision.
Key Terms
Cervicomental Angle: The angle formed between the chin (mentum) and the neck (cervix), a key metric in facial aesthetics.
Deep-Plane Facelift: A surgical technique that repositions the deeper layers of facial tissue (including the SMAS) rather than just the skin.
Hematoma: A solid swelling of clotted blood within the tissues, which in the neck can lead to life-threatening airway compression.
Iatrogenic: Referring to an illness or complication caused by medical examination or treatment.
Lingual Nerve Paresthesia: A sensation of tingling, tickling, or numbness of the tongue, often associated with intraoral surgical approaches.
Marginal Mandibular Nerve (MMN): A branch of the facial nerve that moves the muscles of the lower lip; injury results in lower lip weakness or asymmetry.
Platysmaplasty: A surgical procedure used to tighten the platysma muscle in the neck to reduce sagging and "bands."
Ptosis: The sagging or drooping of an organ or tissue; in this context, the downward displacement of the submandibular gland.
Rhytidectomy: Commonly known as a facelift, a procedure intended to remove wrinkles and tighten facial skin.
Sialocele: A localized collection of saliva within the tissues, typically caused by trauma or surgery to a salivary gland or duct.
Submandibular Gland (SMG): One of the major salivary glands located beneath the floor of the mouth and the mandible.
Xerostomia: The subjective feeling of oral dryness (dry mouth) resulting from reduced or absent salivary flow.
