Outcomes for multilevel surgery for sleep apnea: Obstructive sleep apnea, transoral robotic surgery, and uvulopalatopharyngoplasty. - The Laryngoscope
This study evaluates the outcomes of multilevel surgery for patients with obstructive sleep apnea (OSA) who underwent transoral robotic surgery (TORS) (i.e., posterior glossectomy and limited lateral pharyngectomy) with uvulopalatopharyngoplasty (UPPP).Prospective, nonrandomized trial with historical controls.All patients underwent pre- and postoperative polysomnography, preoperative magnetic resonance imaging of the neck, preoperative drug-induced sleep endoscopy, surgery, including UPPP if this had not occurred previously, and OSA TORS. Outcomes measures included apnea-hypopnea index (AHI), Epworth Sleepiness Scale (ESS), O2 saturation nadir, and total sleep time spent at <90% O2 saturation.Patients who had no prior surgery achieved an average AHI reduction from 58.4 to 19.5 (67%, P < .0001), a surgical success rate of 56%, and a surgical response rate of 73%. Patients with prior pharyngeal surgery achieved an AHI reduction from 55.0 to 45 (24%, P = .19), a surgical success rate of 30%, and a surgical response rate of 40%. Total sleep time spent at <90% O2 saturation was improved from 14% to 3.6% (P < .0003) for patients without prior surgery, and 21.1% to 12.5% (P < .17)for those with prior surgery. ESS improved for all patients combined from 12.8 to 5.8 (P < .0001).Outcomes for the combined approach of OSA TORS and UPPP provide strong evidence in favor of this multilevel approach for the surgical management of OSA. The benefit of the current surgical approach is most significant for previously unoperated patients.4. Laryngoscope, 2015.© 2015 The American Laryngological, Rhinological and Otological Society, Inc.
Transoral robotic surgery-assisted excision of a congenital cervical salivary duct fistula presenting as a branchial cleft fistula. - Head & neck
Congenital cervical salivary duct fistulae are rare entities and can mimic branchial cleft fistulae. Ectopic salivary tissue associated with these pharyngocervical tracts may have malignant potential.We present a case report of a novel surgical approach and review of the literature. A 27-year-old man presented with complaint of drainage from the right side of his neck since early childhood. A tract was found from the posterior tonsillar pillar into the neck and ectopic salivary tissue was found along the tract. A congenital hearing loss was also present. Transoral robotic (TORS)-assisted surgery was used in the management of this patient and allowed excellent visualization of the pharyngeal component of the lesion and a minimally invasive approach. The patient did well with no recurrence.TORS was helpful for management of a congenital salivary fistula and may be helpful for branchial cleft fistulae. These lesions may be associated with the branchio-oto-renal (BOR) syndrome. © 2015 Wiley Periodicals, Inc. Head Neck, 2015.© 2015 Wiley Periodicals, Inc.
Management of an expansile orbital mass: Plexiform neurofibroma decompression by orbitozygomatic approach. - The Laryngoscope
Neurofibromatosis types 1 (NF-1) and 2 are significant entities to otolaryngologists because they frequently involve head and neck skin, brain, skull base, orbits, and surrounding neural and vascular structures. We present the case of a 52-year-old male with progressive, marked unilateral proptosis due to a multilobulated orbital mass, secondary to biopsy-proven plexiform neurofibroma (PN). Acute worsening of proptosis leading to corneal abrasion, diplopia, and pain required debulking surgery, for which an orbitozygomatic approach was utilized. Genetic testing for NF-1 revealed no mutation. This rare case of NF-negative orbital PN and multidisciplinary treatment considerations for expansile orbital tumors are discussed.NA Laryngoscope, 2015.© 2015 The American Laryngological, Rhinological and Otological Society, Inc.
Positron emission tomography in Warthin's tumor mimicking malignancy impacts the evaluation of head and neck patients. - American journal of otolaryngology
1) To determine SUVs and PET/CT characteristics of Warthin's tumors in patients presenting to a head and neck cancer clinic. 2) To analyze the impact of PET/CT on the clinical course of these patients.This is a single-institution retrospective analysis of patients with proven Warthin's tumors who underwent PET/CT done at or near the time of diagnosis and presented to a head and neck cancer practice. Data were obtained from the electronic medical records of these patients and the imaging and pathology databases.Six patients with Warthin's tumor met the criteria for and form the study cohort. Three patients had bilateral tumors. The SUVs for Warthin's varied from 3.4 to 16.1 in these patients, with an average of 7.8 and these SUVs were higher for Warthin's than for the cancers. These findings on PET/CT in this group required additional workup of all patients and required FNA, surgery or SPECT-CT to confirm the diagnosis.Although it is known that Warthin's tumor may be hypermetabolic on PET, this finding in the parotid or neck on PET/CT alters the evaluation and treatment of head and neck cancer patients and patients with cancers outside the head and neck by raising the concern about metastatic disease or multiple primary cancers. In other patients, PET/CT obtained for other reasons may prompt concern about incidental malignancy. This series specifically characterizes clinical features, SPECT-CT and FNA findings that can help reinforce the diagnosis of Warthin's and facilitate management.Copyright © 2015 Elsevier Inc.

HPV-related oropharyngeal cancer: Risk factors for treatment failure in patients managed with primary transoral robotic surgery. - Head & neck
The purpose of this study was to determine clinical factors that predict locoregional recurrence or distant metastasis in patients with human papillomavirus (HPV)-positive oropharyngeal cancer treated with surgery and guideline-indicated adjuvant therapy.We identified all presumed HPV-positive patients with oropharyngeal cancer in our health system from January 2010 to August 2012 treated with surgery and guideline-indicated adjuvant therapy. Statistical analysis was performed to identify clinical predictors associated with treatment failure.One hundred fourteen p16+ oropharyngeal cancers managed with initial surgical resection were identified. Median follow-up was 17 months. Two-year locoregional failure was 3.3% and distant failure was 8.4%. Statistical analysis found that conventional poor prognostic features did not predict treatment failure.Locoregional recurrence and development of distant metastatic disease are uncommon in patients who are appropriately selected for surgical management of p16+ oropharyngeal cancer regardless of the presence or absence of conventional poor prognostic features. © 2014 Wiley Periodicals, Inc.

Salivary neoplasms presenting with radiologic venous invasion: an imaging pearl to diagnosing metastatic renal cell carcinoma. - ORL; journal for oto-rhino-laryngology and its related specialties
We report the case of a 64-year-old otherwise healthy woman who presented with left facial swelling. Imaging of the neck revealed multiple masses in the salivary and thyroid glands. The mass in the left parotid gland was associated with an intravenous extension into the retromandibular, facial and internal jugular veins in the left neck. Based on multiplicity of these masses and the presence of radiologic venous invasion, the diagnosis of metastatic renal cell carcinoma (RCC) was suggested on imaging, which was subsequently confirmed on systemic workup and pathology findings. Although RCC metastasizes to the salivary glands, the primary presentation of RCC with both salivary and thyroid gland masses is extremely rare, with only a few reports. The above feature and its imaging diagnosis based on local venous invasion are the highlights of this report.© 2014 S. Karger AG, Basel.
Transoral robotic surgery in head and neck cancer: what radiologists need to know about the cutting edge. - Radiographics : a review publication of the Radiological Society of North America, Inc
The evolution of oncologic surgical technology has moved toward reducing patient morbidity and mortality without compromising oncologic resection or oncologic outcomes. The goals in treating head and neck cancer are to cure patients, as well as to provide quality of life by improving functional and social outcomes through organ-preservation therapies, which may include surgery, chemotherapy, and/or radiation therapy. Transoral robotic surgery (TORS) is an emerging technique that provides several benefits over existing treatment regimens and over open surgery for head and neck cancer, including reductions in operative times, blood loss, intensive care unit stays, and overall duration of patient hospitalization. Transoral robotic techniques allow wide-view, high-resolution, magnified three-dimensional optics for visualization of the mucosal surfaces of the head and neck through an endoscope, while avoiding the extensive external cervical incisions often required for open surgeries. Radiologists play an important role in the successful outcome of these procedures, both before and after TORS. Determining a cancer patient's surgical candidacy for TORS requires a thorough preoperative radiologic evaluation, coupled with clinical and intraoperative assessment. Radiologists must pay particular attention to important anatomic landmarks that are clinical blind spots for surgeons. Knowledge of the expected postoperative imaging appearances, so that they can be distinguished from recurrent disease and second primary tumors, is essential for all radiologists involved in the care of these patients.
Supracricoid partial laryngectomy for primary and recurrent laryngeal cancer. - JAMA otolaryngology-- head & neck surgery
Supracricoid partial laryngectomy (SCPL) is an essential technique in the armamentarium of modern laryngeal organ preservation surgery. OBJECTIVE, DESIGN, SETTING: Retrospective case series to review the oncologic outcomes following SCPL in a large US-based cohort treated by a single surgeon in a tertiary-care university hospital.A total of 96 consecutive patients with primary or recurrent squamous cell carcinoma of the larynx undergoing SCPL from 1992 to 2010.Supracricoid partial laryngectomy surgery.Five-year local control and laryngeal preservation, using the Kaplan-Meier method.There were 54 primary laryngeal carcinomas and 42 previously treated with radiation to the larynx; 23% were supraglottic or transglottic tumors (n = 22). The overall 5-year local control rate for the series was 94%. For T2 and T3 primary tumors, the 5-year local control was 100% and 96%, respectively. In patients previously treated with radiation, the 5-year local control was 89%, with an 89% laryngeal preservation rate. Among stage III or IV primary laryngeal tumors for which concurrent chemoradiation was a treatment alternative, the 5-year local and locoregional control was 96% and 83%, respectively, and the 5-year larynx preservation was 91%. Ultimate local control was achieved for all patients in the series. A significant postoperative complication occurred in 19% (n = 18) and 1 anesthesia-related perioperative death occurred. No total laryngectomies were performed for laryngeal dysfunction.This series demonstrates excellent local control for both primary and recurrent laryngeal cancers, with functional larynx preservation. In appropriately staged and selected patients with T2 or T3 primary laryngeal cancer or laryngeal cancer following prior radiation treatment, SCPL should be considered as a treatment alternative to non-surgical treatment or total laryngectomy.
Chordoma of the anterior cranial fossa and ethmoids with orbital involvement. - Orbit (Amsterdam, Netherlands)
To report a case of orbital chordoma, emphasizing the clinical, operative, and histopathologic findings, and to review similar English-language reports.This is a single case report with histopathologic correlation. Search of the English-language literature and review of referenced citations was performed.After treatment with resection and proton beam radiation, our patient is alive, without recurrence at 3-year follow-up. Biopsy of the recurrent tumor was consistent with chordoma. The original biopsy had S100 and pancytokeratin-positive tumor cells, with abundant clear to eosinophilic cytoplasm. Focal EMA positivity was present. Literature review identified 14 additional cases.Orbital chordoma is rare. Extraocular motility disturbances occur solely with intracranial lesions as well as those extending into the orbit, but globe displacement is the most common sign of orbital involvement. This tumor often recurs in the path of previous resection. Diagnosis is confirmed by distinctive histopathologic features and positive staining for S100, pancytokeratin, and EMA. Treatment and outcome analysis of orbital chordoma is difficult due to its rarity and lack of reported follow-up and may need to be extrapolated from reported skull base cases.
Molecular basis of posttransplant squamous cell carcinoma: the potential role of cyclosporine a in carcinogenesis. - The Laryngoscope
Cyclosporine (CSA) is a widely used immunosuppressive agent, predominantly for transplant patients. It is well recognized that transplant patients are prone to develop squamous carcinoma of the skin and mucosa, and this high incidence of squamous carcinoma in the transplant population cannot be explained by immunosuppression alone. We hypothesize that CSA may play a significant role in the transformation of normal epidermal squamous cells to carcinoma. CSA is a specific ligand for calcineurin, a ubiquitously expressed cellular serine/threonine phosphatase, that plays important roles in the immune system and cardiac muscles. Using global gene-profiling methods, we studied the short-time CSA effect on the squamous cell line (SCC-015) using Affymetrix human gene chips (Human U133, 2.0 plus chip). Multiple groups of genes were identified to be responsive to CSA treatment, including many genes of unknown functions. We then used reverse transcriptase-polymerase chain reaction and immunoblot analyses to selectively confirm the results from the chips analyses with emphasis on the regulatory molecules important for cellular functions of apoptosis, DNA damage repair, and cellular transformation. This global gene-profiling study indicated that CSA not only functions as an immunosuppressant on the immune system, but also activates/inhibits a wide array of genes important for cell-cycle regulation, apoptosis, and oncogene/tumor-suppressor activation. These functions of CSA on skin and mucosa systems at the molecular level are likely important in the pathogenesis of squamous carcinoma in transplant patients.
