Is malignant otitis externa on the increase? A retrospective review of cases

February 20, 2017  |  Diana Bhasker, MBBS, MRCS(ENT); Angela Hartley, MBchB; Frank Agada, FRCS, RCS(ORL-HNS)

Abstract

We performed a retrospective review of all patients with malignant otitis externa (MOE) treated in our center between July 2004 and December 2012 to evaluate the current epidemiology in our region and to ascertain causative factors associated with the perceived increase in the number of cases diagnosed. Eleven patients were identified (5 men and 6 women), with a mean age of 77 years (range: 38 to 97 years). Diabetes was present in 36%. Pseudomonas aeruginosa was the causative organism in 64% of cases; all pathogens were sensitive to ciprofloxacin. We noted a significant increase in the diagnostic frequency of MOE during the study period (p = 0.0027) No obvious causative factors were identified. Due to the mortality associated with this condition, further studies are required to establish national trends.

Radiofrequency turbinate volume reduction vs. radiofrequency-assisted turbinectomy for nasal obstruction caused by inferior turbinate hypertrophy

February 20, 2017  |  Saumitra Kumar, MS(ENT); Trivender Singh Anand, MS(ENT), PhD; Indranil Pal, MS(ENT)

Abstract

Radiofrequency procedures are a well-accepted treatment for nasal obstruction. We conducted a randomized, noncontrolled study to compare the effectiveness of submucosal bipolar radiofrequency turbinate volume reduction (RFTVR) and bipolar radiofrequency-assisted turbinectomy (RFaT) in patients presenting with nasal obstruction caused by inferior turbinate hypertrophy. A total of 30 patients-15 males and 15 females, aged 15 to 60 years (mean: 32)-were randomly divided into one of the two homogeneous treatment groups. Outcomes were determined by comparisons of subjective symptom scores on a visual analog scale and by anterior active rhinomanometry at postoperative days 7, 14, and 28 and again at 6 months postoperatively. Both groups demonstrated significant and similar improvements in nasal airway function both subjectively and objectively. However, we noted that the incidence of adverse effects and postoperative morbidity was higher in the RFaT group. Therefore, we conclude that when surgery is indicated, RFTVR is the preferred treatment for nasal obstruction secondary to inferior turbinate hypertrophy. RFaT is equally effective, but it is associated with a slightly higher incidence of adverse effects.

February 20, 2017  |  Cheng-Ping Shih, MD; Yu-Ching Chou, PhD; Hsin-Chien Chen, MD, PhD; Jih-Chin Lee, MD; Yueng-Hsiang Chu, MD, PhD; Chih-Hung Wang, MD, PhD

Abstract

Sudden sensorineural hearing loss is characterized by a rapid-onset hearing loss that develops within 3 days. Vertigo may also be present. We conducted a retrospective study to investigate whether the severity of a loss of caloric function is associated with the initial hearing loss and with hearing recovery. Our study population was made up of 135 patients-67 men and 68 women, aged 25 to 71 years (mean: 50.9)-with sudden sensorineural hearing loss who had undergone bithermal caloric testing. We compared various patient factors according to patients' hearing level and their response to caloric testing. We also analyzed the canal paresis (CP) value in patients with an abnormal caloric response according to three factors: disease severity, vertigo, and hearing recovery, and we evaluated the correlation between the loss of caloric function and hearing outcomes. We found that an abnormal caloric response was significantly associated with a profound hearing loss at presentation, the presence of vertigo, and poor hearing recovery. Among patients with an abnormal caloric response, the CP value was significantly correlated with hearing recovery (r = 0.503, p = 0.001). Poor hearing recovery was seen in 80% of patients with a CP value of ≥40% but in only 25% of patients with a value of <40%; in addition, the degree of hearing recovery was worse in the patients with a CP value of ≥40% (p = 0.002). We conclude that a CP value of ≥40% is a significant prognostic factor for an unfavorable treatment outcome.

Predictors of adverse events after neck dissection: An analysis of the 2006-2011 National Surgical Quality Improvement Program (NSQIP) Database

February 20, 2017  |  Umang Jain, BS; Jessica Somerville, MD; Sujata Saha, BS; Jon P. Ver Halen, MD; Anuja K. Antony, MD, MPH; Sandeep Samant, MD; John Y. Kim, MD

Abstract

While neck dissection is an important primary and adjunctive procedure in the treatment of head and neck cancer, there is a paucity of studies evaluating outcomes. A retrospective review of the National Surgical Quality Improvement Program (NSQIP) database was performed to identify factors associated with adverse events (AEs) in patients undergoing neck dissection. A total of 619 patients were identified, using CPT codes specific to neck dissection. Of the 619 patients undergoing neck dissection, 142 (22.9%) experienced an AE within 30 days of the surgical procedure. Risk factors on multivariate regression analysis associated with increased AEs included dyspnea (odds ratio [OR] 2.57; 95% confidence interval [CI] 1.06 to 6.22; p = 0.037), previous cardiac surgery (OR 3.38; 95% CI 1.08 to 10.52; p = 0.036), increasing anesthesia time (OR 1.005; 95% CI 1 to 1.009; p = 0.036), and increasing total work relative value units (OR 1.09; CI 1.04 to 1.13; p < 0.001). The current study is the largest, most robust analysis to identify specific risk factors associated with AEs after neck dissection. This information will assist with preoperative optimization, patient counseling, and appropriate risk stratification, and it can serve as benchmarking for institutions comparing surgical outcomes.

Alteration of serum levels of inflammatory cytokines and polysomnographic indices after uvulopalatal flap surgery in obstructive sleep apnea

February 20, 2017  |  Murad Mutlu, MD; Erkan Vuralkan, MD; Istemihan Akin, MD; Hikmet Firat, MD; Sadik Ardic, MD; Sevgi Akaydin, PhD; Ece Miser, PhD

Abstract

The aim of the current study was to compare the changes in polysomnographic indices and serum levels of C-reactive protein (CRP), cystatin C, tumor necrosis factor-α (TNF-α), and intercellular adhesion molecule-1 (ICAM-1) in patients with obstructive sleep apnea (OSA) who were treated surgically via a uvulopalatal flap (UPF) technique. Twenty-five patients (14 men, 11 women), average age 46.2 ± 9.3 years, who underwent UPF surgery were included in this study. Serum biochemical analyses and polysomnographic examinations were performed before and 6 months after the surgery. Pre- and postoperative values of apnea hypopnea index (AHI), oxygen desaturation index (ODI), and minimum oxygen concentrations, as well as serum levels of CRP, cystatin C, TNF-α, and ICAM-1 were compared. Comparison of variables before and after UPF surgery demonstrated that AHI (p = 0.001), ODI (p < 0.001) and oxygen saturation (p < 0.001) were significantly improved. In addition, serum levels of CRP (p = 0.036), cystatin C (p = 0.005), TNF-α (p < 0.001), and ICAM-1 (p < 0.001) were significantly reduced 6 months after surgery. Our results suggest that UPF is an effective surgical method that alleviates the severity of OSA. Moreover, it may have the potential to prevent the development of atherosclerosis by attenuating the inflammatory process induced by activation of inflammatory mediators such as CRP, TNF-α, ICAM-1, and cystatin C.

Simultaneous binaural bithermal caloric testing: Clinical value

January 25, 2017  |  Robert T. Sataloff, MD, DMA, FACS; Meghan L. Pavlick, AuD, FAAA; James (Drew) McCaffrey, MD; John M. Davis, MD; Shannon M. Stewart, AudD

Abstract

The aim of this retrospective review was to determine the clinical value of simultaneous binaural bithermal caloric testing (SBT) versus alternate binaural bithermal caloric testing (ABB) in the setting of a tertiary care neurotology clinic. Charts of 131 adults who had presented with otologic complaints and had undergone both SBT and ABB examinations were included in the study. The main outcome measure was the identification of peripheral hypofunction. One hundred two patients had a normal ABB caloric examination; 86 of those 102 patients (84.3%) had normal ABB examinations but abnormal SBT results. We conclude that SBT is a more sensitive measure of peripheral pathology than the traditional ABB examination. If peripheral pathology is suspected but not confirmed by ABB, SBT appears useful for detecting mildly reduced vestibular response.

Extraosseous Ewing sarcoma: Expanding the differential diagnosis of supraclavicular fossa tumors

January 25, 2017  |  Julio Rama-L&oacute;pez, MD, PhD; Rafael Ramos Asensio, MD; Cesar Garc&iacute;a-Garza, MD; Pablo Luna Fra, MD; Maria del Carmen Gassent Balaguer, MD; Jos&eacute; Fuster Salva, MD

Abstract

A broad spectrum of diseases can be included in the differential diagnosis of neck masses. We report a case of extraosseous Ewing sarcoma that presented as a neck mass in a 70-year-old man. To the best of our knowledge, this is the first reported case of extraosseous Ewing sarcoma of the supraclavicular fossa. Published cases of extraosseous Ewing sarcoma in the neck have been described in other age groups, but those tumors were confined to the parapharyngeal space. Also, there have been reported cases in patients older than 70 years in which Ewing sarcoma affected other structures such as the larynx and the pelvis, but none in the soft tissues of the neck. This case adds extraosseous Ewing sarcoma as a possible diagnosis to consider when evaluating a neck mass in the supraclavicular fossa.

Obstructing in utero oropharyngeal mass: Case report of a lymphatic malformation arising within an oropharyngeal teratoma

January 25, 2017  |  Todd J. Wannemuehler, MD; Christopher R. Deig, BA; Brandon P. Brown, MD; Stuart A. Morgenstein, DO

Abstract

An ex utero intrapartum treatment procedure was performed to deliver a fetus with a multiseptated, entirely cystic, 4.5 x 5.0 x 4.0-cm mass occupying the oropharynx and oral cavity with protrusion from the mouth. Surgical excision was performed, and final pathologic diagnosis revealed a lymphatic malformation arising within a cystic oropharyngeal teratoma. Lymphatic malformations are virtually indistinguishable radiologically from rare, purely cystic teratomata, and efforts have been made to distinguish between the two in utero because of differing available treatment modalities. This represents the first documented case in the literature of a lymphatic malformation arising from within an oropharyngeal teratoma.
