Indications for Facial Nerve Monitoring During Parotidectomy

xlomafota13 shared this article with you from Inoreader
Facial nerve injury is the most feared complication during parotid surgery. Intraoperative electromyographic nerve monitoring can be used to identify the facial nerve, map its course, identify surgical maneuvers detrimental to the nerve, and provide prognostic information. Data regarding outcomes with facial nerve monitoring are heterogeneous. In contrast, the incidence of permanent weakness has not been shown to be significantly affected by use of nerve monitoring. For revision surgery, studies show that monitored patients had (1) weakness that was less severe with quicker recovery and (2) shorter operative times compared with unmonitored patients.

Transoral Excision of Parapharyngeal Space Tumors

xlomafota13 shared this article with you from Inoreader
Transoral excision of parapharyngeal space (PPS) tumors has increased in popularity along with the increased use of robotic and endoscopic surgical technology. Here, the authors highlight the indications, techniques, outcomes, and complications of transoral approaches to PPS tumors, with a special emphasis on salivary tumors of the PPS and the transoral robotic surgery approach.

Incorporating Sialendoscopy into the Otolaryngology Clinic

xlomafota13 shared this article with you from Inoreader
Simple sialendoscopy procedures may be performed in the outpatient clinic with few complications. This process spares patients the risks, increased cost, and time burdens of sialendoscopy under general anesthesia. Sialendoscopy procedures may be incorporated into the outpatient practice after gaining experience with these procedures in the operating room. Diagnostic sialendoscopy, dilation of stenosis, and endoscopic sialolithotomies of small, freely mobile stones are appropriate for in-office sialendoscopy in many instances.

Management of Mucoceles, Sialoceles, and Ranulas

xlomafota13 shared this article with you from Inoreader
Mucoceles are common salivary gland disorders. Mucoceles are benign, mucus-filled extravasation pseudocysts that commonly arise on the lower lip of children and young adults. Although surgical excision is commonly performed to remove these lesions, other treatments include marsupialization, micromarsupialization laser ablation, cryotherapy, intralesional steroid injection, and sclerosing agents. Traumatic sialoceles commonly arise from injury to the parotid duct. Treatment of sialoceles from acute parotid duct injury and for delayed presentations after injury are discussed. Ranulas are a subtype of mucocele from the sublingual gland classified as superficial or plunging. Treatment of ranulas must address the sublingual gland.

Management Options for Sialadenosis

xlomafota13 shared this article with you from Inoreader
Sialadenosis (sialosis) is a chronic, noninflammatory, nonneoplastic, bilateral, often painless enlargement of the salivary glands, most frequently affecting the parotid glands. Approximately 50% of cases are associated with an underlying disease process. The pathogenesis of sialadenosis is unknown but likely results from an autonomic neuropathy. The key to management is diagnosis and management of any poorly controlled underlying medical process.

Soft Tissue Reconstruction of Parotidectomy Defect

xlomafota13 shared this article with you from Inoreader
This article provides a review of soft tissue reconstructive options for the parotidectomy defect, including skin incision, primary closure, acellular dermis, autologous fat transfer, local and regional flaps, and free tissue transfer. The authors discuss considerations for volume enhancement, skin coverage, prevention of Frey syndrome, tumor surveillance, and potential complications.

Transoral Sialolithotomy Without Endoscopes

xlomafota13 shared this article with you from Inoreader
Sialoendoscopy is a valuable technique for a variety of obstructive and nonobstructive disorders of the major salivary glands. However, the utility of sialoscopes is limited for salivary stones, which frequently required open removal. Transoral sialolithotomy without scopes is an efficient, low-cost alternative with excellent outcomes available for most of the submandibular stones.
