Absence Of Submandibular Gland Research Articles

CT and MR Imaging Appearance of the Pedicled Submandibular Gland Flap: A Potential Imaging Pitfall in the Posttreatment Head and Neck.

Pedicled locoregional submandibular gland reconstruction flaps are increasingly used in oncologic head and neck surgery and have unique imaging characteristics that can mimic locally recurrent tumor. In this clinical report, 23 posttreatment imaging studies were evaluated in 19 patients who had undergone submandibular gland flap reconstructions after resection of a primary head and neck tumor. Submandibular gland flaps were most commonly mobilized into the parapharyngeal space or parotid bed, with others located inferior to the mandibular body and within marginal mandibulectomy defects. The original shape of the gland was typically not preserved. Identifying the submandibular gland hilum, vascular pedicle, glandular texture, and absence of submandibular gland in the orthotopic location was most useful in recognizing a flap. The interpreting radiologist must be familiar with the unique submandibular gland flap imaging characteristics to accurately differentiate normal postoperative appearance and recurrent tumor.

Bilateral submandibular gland agenesis with bilateral parotid hypertrophy: a rare presentation

<p class="abstract"><span lang="EN-IN">Recurrent laryngeal nerve injury and hypoparathyroidism are two of the much discussed major complications Bilateral submandibular gland aplasia associated with bilateral hypertrophy of parotid gland is one of the rarest case presentation. The enlargement of parotid gland is mostly due to a compensatory mechanism of submandibular aplasia. This case report describes a 45 year female presented with diffuse swelling over bilateral preauricular and infraauricular area. CECT of face confirmed diffuse bilateral parotid gland enlargement associated with absence of submandibular gland.</span></p>
