A novel distending laryngoscope: implications in transoral surgery.

The objective is to describe an innovative laryngoscope developed to improve visualization, provide greater exposure, and enhance precision and success during transoral procedures. A retrospective review of 170 patients who underwent transoral surgery with a new distending laryngoscope was conducted. We compared and contrasted our exposure within the oropharynx, hypopharynx, and larynx using the laryngoscope with that of currently available instrumentation. Specific mechanical dimensions of the laryngoscope along with the provided working field were calculated. Experience with the new laryngoscope afforded improved exposure over currently available instrumentation. This laryngoscope was manufactured using design elements from the Steiner, Weerda, and Lindholm laryngoscopes, including an anteriorly curved distal tip, distending capability, and lateral wings to protect against tongue herniation. The panoramic view was increased allowing for wider exposure of the supraglottis and pharynx. This design provided enhanced transoral visibility and working room for improved bimanual instrumentation. Direct laryngoscopic technique and instrumentation have continued to evolve. Over the last two decades, there has been a significant movement towards minimally invasive transoral surgical techniques fueling innovative concepts and advancement in laryngoscopic design and application. We present our experience with an innovative laryngoscope allowing for improved visualization, greater exposure, and enhanced proficiency with transoral technique.

Orbital Complications Associated with the Treatment of Chronic Rhinosinusitis.

Orbital injuries from endoscopic sinus surgery are rare but potentially catastrophic. The most feared complications from sinus surgery include blindness and diplopia. Recent publications note that the rate of orbital complications has decreased when compared with the past, reflecting the use of endoscopes, better technology, and improved training. The sinus surgeon must have mastery over the procedure she or he plans to undertake and be aware of the specific potential for orbital injury given the patient's anatomy and disease. The sinus surgeon must also have expert knowledge of the appropriate and immediate medical and surgical management of orbital complications.

The Mayo Clinic Arizona Spasmodic Dysphonia Experience: A Demographic Analysis of 718 Patients.

OBJECTIVE: Analyze demographic data collected over a 25-year experience of 718 patients with spasmodic dysphonia (SD) who have been treated with botulinum toxin-A (BoNT-A) and compare our data with previously published studies. METHODS: Seven hundred eighteen patients with SD were treated with 6621 BoNT-A injections at Mayo Clinic Arizona between 1989 and 2014. All patients were treated by the same physician team. Background demographic data for each patient were recorded. RESULTS: Of 718 patients, 557 patients were female (77.6%). Six hundred sixty of 718 (91.8%) patients had adductor SD (AdSD), and 58 of 718 (8.1%) patients had abductor SD (AbSD). Average age of onset was 51 years. Of 718 patients, 378 (52.6%) had vocal tremor (VT); VT was present in 54.4% of AdSD patients and 32.1% of AbSD patients. Thirty-seven of 718 (5.2%) patients had other dystonias, including cervical dystonia (2.3%), blepharospasm (1.4%), limb dystonia (1.1%), and oromandibular dystonia (0.3%). A positive family history of SD was present in only 6 of 718 patients (0.8%) and of other dystonias in 11 of 718 patients (1.5%). CONCLUSIONS: Spasmodic dysphonia is a chronic and potentially disabling focal laryngeal dystonia. The Mayo Clinic Arizona SD experience compares to prior reports and reveals a female preponderance, onset in middle age, infrequent hereditary pattern, high co-occurrence of VT, and low co-occurrence of other dystonias.

Severe prolonged dysphagia following transoral resection of bilateral synchronous tonsillar carcinoma.

OBJECTIVES: Alert the reader to the complication of severe dysphagia following transoral laser microsurgery (TLM) or transoral robotic surgery (TORS) for bilateral simultaneous or synchronous tonsillar squamous cell carcinoma. METHODS: A case series of four patients treated at an academic tertiary center between 2008 and 2012 is presented; two treated with transoral laser microsurgery and two with transoral robotic surgery for biopsy-proven untreated bilateral primary squamous cell carcinoma. Main outcome measures included functional swallowing determined by the Functional Outcome Swallowing Scale. The incidence of significant postoperative complications was recorded. RESULTS: Two patients had surgery for discontiguous involvement of bilateral palatine tonsils with squamous cell carcinoma, while two patients had surgery for bilateral tonsillar squamous cell carcinoma with unilateral extension into the base of tongue. Complete swallowing failure as characterized by the Functional Outcome Swallowing Scale was seen postoperatively in 3/4 patients who underwent TLM or TORS for bilateral simultaneous tonsillar carcinoma, while one patient was lost to follow-up. CONCLUSIONS: Severe dysphagia in the setting of bilateral oropharyngectomy for simultaneous or synchronous tonsillar squamous cell carcinoma is rarely described but a significant concern. In an era with increased use of transoral surgery as de-escalation therapy, this unusual complication warrants consideration. We report that transoral bilateral pharyngectomy is quite harmful to near-term and intermediate-term swallowing outcomes. This paper serves to provide warning against primary surgical intervention in this setting, while demonstrating that non-surgical treatment may be the best viable option.

Contemporary applications of frontal sinus trephination: A systematic review of the literature.

Our objective was to perform a systematic review of the literature on contemporary indications and outcomes for frontal sinus trephination and present an illustrative case of an endoscopically assisted repair of a subcutaneous frontal sinus fistula by trephination technique. PubMed and Ovid databases were used as data sources. A systematic review of the English literature was completed to review reports of frontal trephination from 1980 to 2014. Articles meeting inclusion criteria for inflammatory and noninflammatory indications were reviewed. Articles were systematically reviewed and graded by evidence-based medicine level. An illustrative case from our institution is then presented. The systematic review identified 2,621 published studies. Thirty-eight studies were identified for inclusion. The indications, techniques, outcomes, safety, and complications were reviewed for noninflammatory and inflammatory conditions. There were 32 retrospective case series, reports, or cohort studies (level 4), four systematic reviews (level 3), one prospective analysis (level 3), and one meta-analysis (level 2). Due to the heterogeneity of study cases and inclusion criteria, a meta-analysis was not feasible. We also present a novel closure of an anterior skull base defect resulting in a subcutaneous fistula with use of a frontal trephination approach. The frontal sinus trephination should not be regarded as a procedure of the past, as it useful in the armamentarium of the modern sinus and skull base surgeon. This approach provides access for instrumentation for hard-to-reach frontal sinus disease either purely through a trephination approach or as a supplementation to the transnasal endoscopic approach. Evidence supporting frontal sinus trephination is of levels 2, 3, and 4. Level of evidence: NA.

Tuberculous retropharyngeal abscess presenting with symptoms of obstructive sleep apnea.

Chronic retropharyngeal abscess (RPA) caused by tuberculosis is an uncommon manifestation of extrapulmonary tuberculosis within the head and neck. Obstructive sleep apnea (OSA) in adults is a common condition with many etiologies that have been well described. Here, we present a case of retropharyngeal abscess caused by chronic tuberculosis with an unusual and interesting presenting symptom in an adult that has not been mentioned in literature, new-onset and worsening stertor or snoring, with signs and symptoms of OSA. The purpose of this manuscript is to present our experience with this case, as well as to emphasize the diagnosis, clinical course, and management of tuberculous retropharyngeal abscess in adults, while also signifying the need to include retropharyngeal abscess in the differential diagnosis for symptoms presenting as new-onset stertor and airway obstruction.

Giant fibrolipoma of the esophagus.

Benign tumors of the esophagus are uncommon, representing <0.5% of esophageal tumors. Fibrolipomas are a subset of benign fibrovascular tumors, which present with dysphagia, odynophagia, and substernal fullness. These intraluminal tumors can become elongated and molded into a long pedunculated polyp by constant peristaltic movements. They can cause esophageal obstruction if large and long enough and can cause asphyxiation if they become lodged into the glottis. A barium swallow is the main diagnostic tool; treatment is surgical via a transoral, transcervical, or transthoracic approach. We report the excision of a large esophageal fibrolipoma through a transoral laser microsurgical approach.

The fourth branchial complex anomaly: a rare clinical entity.

Fourth branchial pouch anomalies are rare congenital disorders of the neck and are a consequence of abnormal development of the branchial apparatus during embryogenesis. Failure to appropriately recognize these anomalies may result in misdiagnosis, insufficient treatment, and continued recurrence. Here, we present an unique presentation of two cases, describe their diagnosis, clinical course, and management, and review the literature regarding these interesting anomalies.
