Submandibular gland excision: short- and long-term complications

Area of Science:

• Otolaryngology
• Oral and Maxillofacial Surgery
• Surgical Outcomes

Background:

• Benign submandibular gland diseases are common indications for surgical intervention.
• Submandibular gland excision is a standard procedure, but potential complications require thorough evaluation.
• Understanding the long-term outcomes and patient satisfaction is crucial for surgical decision-making.

Purpose of the Study:

• To evaluate the short- and long-term complications of benign submandibular gland excisions.
• To assess patient satisfaction and functional recovery following the procedure.
• To analyze the incidence of residual stones in Wharton's duct after surgery for salivary stones.

Main Methods:

• Retrospective review of 159 benign submandibular gland excisions in 157 patients over a 10-year period.
• Follow-up evaluation of 86 patients to assess complications and outcomes.
• Documentation of neurapraxia, scar issues, sensory changes, salivation, taste perception, and residual stones.

Main Results:

• Facial nerve neurapraxia occurred frequently but showed a high recovery rate (92.3%).
• Scarring, altered sensation, reduced salivation, and taste changes were reported but rarely led to dissatisfaction.
• 18.2% of patients with salivary stones had residual stones in Wharton's duct post-excision.

Conclusions:

• Submandibular gland excision is associated with a high rate of functional recovery, particularly for the facial nerve.
• While complications like scarring and sensory changes occur, patient satisfaction remains generally high.
• Bilateral submandibular gland removal necessitates careful consideration due to the risk of developing xerostomia (dry mouth).
