Each anterior marginal nerve passes along the marginal muscle of the preoral lobe and contains 4 5 bipolar serotonin-like immunoreactive perikarya.
One of these cases was considered to be a treatment-related serious adverse event (temporary asymmetric smile possibly associated with injury to the branch of the marginal mandibular nerve on the right side of the face).
One patient experienced a temporary marginal mandibular nerve palsy that resolved, and 1 postoperative wound infection was encountered.
34 Another option to improve identification in level I is to perform some initial dissection below the level of the marginal mandibular nerve, transecting the tissues down to the level of the mylohyoid muscle.
These events were possibly the result of injections administered too deeply into the platysma muscle or too close to the marginal mandibular nerve, emphasizing the importance of proper injection location and technique and of good knowledge concerning the relevant anatomy and anatomic landmarks.
The conventional treatment method of transcervical resection has some risks such as paresis of the marginal branch of the facial nerve, lingual nerve paresis, xerostomia, and an unsatisfactory cosmetic result [2].
Overall, marginal excision of peripheral nerve sheath tumours in dogs resulted in a long survival time, but adjuvant treatment with recombinant human interleukin-2 (rhIL-2) did not provide a survival advantage.
Skin flap elevation below the mandible should be performed carefully to minimize injury to the nearby marginal branch of the facial nerve.
Complications from submental endotracheal intubation do occur and include bleeding, damage to the lingual nerve, and the marginal mandibular branch of the facial nerve, damage to the duct of the submandibular gland, damage to the sublingual gland, salivary fistulae, and skin infections [ 64, 65].
Of course, if vital organs or important vessels or nerves are nearby, marginal excision is performed inevitably and if malignancy is confirmed, radiotherapy must be further performed.
Second, avoid damage to the marginal mandibular branch of the facial nerve during tunneling.
