Endoscopic extruded screw removal after anterior cervical disc fusion: technical case report.

Objective And Importance: Symptomatic complications related to screw migration and extrusion after anterior cervical disc fusion are uncommon.

Clinical Presentation: We report a case of significant dysphagia owing to late screw migration.

Intervention: An endoscopic transpharyngeal removal was performed without pharyngeal closure and with relief of symptoms.

Clinical characteristics and treatment outcome for nonvestibular schwannomas of the head and neck.

Purpose: Studies involving head and neck schwannomas have focused predominantly on involvement of the vestibulocochlear nerve complex (acoustic neuroma) because of the associated morbidity related to lesions involving that region. However, the majority of head and neck schwannomas are not of vestibular nerve origin and may also produce significant morbidity due to involvement of the orbit, skull base, and cranial nerves. The purpose of this study is to examine the presenting signs and symptoms, location, nerve of origin, and outcome after treatment of patients with nonvestibular schwannomas of the head and neck.

Postoperative imaging and follow-up of vestibular schwannomas.

Objective: No standards exist regarding patient follow-up after complete vestibular schwannoma resection. We surveyed neurotologists and neurosurgeons to determine practice patterns.

Study Design: A nonrandomized sample of American Neurotology Society and North American Skull Base Society members was surveyed.

A new assay to screen for head and neck squamous cell carcinoma using the tumor marker metallopanstimulin.

Objective: To date, no serologic marker has proven effective as a diagnostic test for head and neck squamous cell carcinoma (HNSCC). Levels of metallopanstimulin (MPS), as measured by a difficult to reproduce radioimmunoassay, are significantly elevated in untreated HNSCC patients. Our objective was to develop a simpler MPS assay.

Report of an obstructive goiter and its surgical treatment during delivery.

We report a case of a morbidly obese young woman in her third trimester of pregnancy presenting with a history of goiter and respiratory disease. The recent history of this patient was significant for worsening respiratory symptoms over a period of 2 weeks, and, on presentation at 36 weeks gestation, she was stridorous, dyspneic at rest, and had a hoarse voice. Evaluation revealed a morbidly obese individual with a large goiter.

Minimally invasive radioguided parathyroidectomy using intraoperative sestamibi localization.

This article presents the authors' technique of minimally invasive radio guided parathyroidectomy (MIRP) with intra-operative use of the hand-held gamma probe for primary HPT caused by a solitary adenoma. It points out how this approach varies from that of others who perform MIRP. It also illustrates ways to troubleshoot common problems with the technique in inexperienced hands.

Sinonasal adenoid cystic carcinoma with widespread symptomatic bony metastasis.

Adenoid cystic carcinoma is a fairly uncommon salivary neoplasm of the head and neck. These lesions often progress insidiously, and they have a propensity for early perineural spread and bony invasion. Distant metastasis to the lungs is fairly common and is usually fatal.
