Beyond the lips: Guidance for intraoral procedures
EXPERT ANALYSIS SUMMER AAD 2019
Postoperative care, complications, and the limits of the dermatologist
Postoperatively, patients should know that swelling is to be expected, especially with procedures like minor salivary gland biopsies that involve the lip. Icing 15 minutes per hour for the first few hours will help with swelling; wound care is optimized with gentle salt water rinses. A bland diet that avoids acidic, spicy, and excessively hot foods and beverages will minimize wound irritation. Foods with sharp edges like chips, crackers, and nuts can actually catch sutures and cause pain and bleeding, so these too should be avoided.
As with dental work, care should be taken with eating or drinking until anesthesia has worn off, which may take up to 3 hours. Patients should also be cautioned that sutures are likely to come out prematurely just because of the mobility of the structures of the mouth with normal activities such as eating and talking.
Should a wound infection occur, said Dr. Fazel, it’s likely that mixed aerobic and anaerobic bacteria are to blame; accordingly, broad-spectrum beta-lactam antibiotics can be a good first-line course. More severe infections are more likely to have an anaerobic or gram-negative etiology; metronidazole is a reasonable choice for anaerobic coverage, she noted. The life-threatening complication not to miss is cellulitis of the floor of the mouth, or Ludwig angina. The swelling results in superior and posterior displacement of the tongue, obstructing the upper airway, so any patient suspected of having Ludwig angina needs emergent evaluation and treatment.
When should a dermatologist consider referral to an otolaryngologist rather than diving into a biopsy in the dermatology clinic? If the area of concern is on the posterior third of the tongue, access without special tools or higher levels of anesthesia becomes tricky, Dr. Fazel pointed out. The posterior hard palate, the soft palate, and the floor of the mouth are also regions best left to otolaryngologists, she said.
