Prior to 1999, the diagnosis of otomycosis as a cause of persistent otorrhea was rare. An increase incidence has been seen in among our outpatient pediatric otolaryngology practice. The purpose of this study is to assess the contribution of ototopical antibiotic drops to the development of otomycosis. DESIGN: Retrospective study. SETTING: Pediatric otolaryngology outpatient center. METHODS: Chart review of all patients diagnosed with otomycosis between June 1999 and September 2001. Twenty-six patients (ages 17 months-29 years) were diagnosed with otomycosis based on clinical and microbiological findings after treatment with topical ofloxacin antibiotic drops. All patients had used ototopical antibiotics, including ofloxacin in every case, for presumed bacterial otorrhea. Once the fungal source was recognized, therapy succeeded in each case (26/26). Physicians need an elevated suspicion of otomycosis as a cause of persistent otorrhea, especially following treatment with topical antibiotic drops. Appropriate treatment of otomycosis eliminates otorrhea. Ofloxacin remains an excellent choice for bacterial otorrhea, but it appears to increase the incidence of otomycosis. Thus, its usage warrants careful post-treatment follow-up.

The modern theory of hoarseness is that there are multifactorial etiologies contributing to the voice problem. The hypothesis of this study is that muscle tension dysphonia is multifactorial with various contributing etiologies. METHODS: This project is a retrospective chart review of all patients seen in the Voice Speech and Language Service and Swallowing Center at our institution with a diagnosis of muscle tension (functional hypertensive) dysphonia over a 30-month period. A literature search and review is also performed regarding current and emerging concepts of muscle tension dysphonia. RESULTS: One hundred fifty subjects were identified (60% female, 40% male, with a mean age of 42.3 years). Significant factors in patient history believed to contribute to abnormal voice production were gastroesophageal reflux in 49%, high stress levels in 18%, excessive amounts of voice use in 63%, and excessive loudness demands on voice use in 23%. Otolaryngologic evaluation was performed in 82% of patients, in whom lesions, significant vocal fold edema, or paralysis/paresis was identified in 52.3%. Speech pathology assessment revealed poor breath support, inappropriately low pitch, and visible cervical neck tension in the majority of patients. Inappropriate intensity was observed in 23.3% of patients. This set of multiple contributing factors is discussed in the context of current and emerging understanding of muscle tension dysphonia. CONCLUSIONS: Results confirm multifactorial etiologies contributing to hoarseness in the patients identified with muscle tension dysphonia. An interdisciplinary approach to treating all contributing factors portends the best prognosis.

This study seeks to determine the ability of enzyme-linked immunosorbent assays (ELISAs) of vocal fold secretions to detect and describe the acute tissue response to injury in a rabbit vocal fold model. Vocal fold secretions were collected before the induction of a unilateral surgical injury to the vocal fold and at 6 timepoints after injury (1, 5, 7, 10, 14, and 21 days). Secretions were then subjected to ELISAs to assess concentrations of interleukin-1 beta (IL-1beta) and prostaglandin-E2 (PGE-2). The results indicate that ELISAs may be useful in documenting fluctuations in these markers associated with the wound healing process in the rabbit model. The temporal expression of both IL-1beta and PGE-2 was consistent with their proposed roles in the wound healing cascade in other systems, pointing to the potential that surface secretions may be at least partial indicators of wound healing events within the tissue

Until recently, researchers used behavioral measures of identification and discrimination of speech and nonspeech stimuli to assess the effects of auditory deprivation, enhancement, and training. Recent advances in our ability to measure electrical activity in the auditory system in response to sound have made it possible for us to study how changes in auditory input (because of hearing loss, auditory input modification, or training) affect the function of the central auditory system. This article reviews the evidence of changes in the auditory cortex in mature animals and in humans with acquired sensorineural hearing loss as well as changes associated with auditory training in persons with normal hearing. The results of studies that measure psychoacoustic and speech-recognition performance of persons with hearing loss, with and without hearing aids, are interpreted within the framework of our new knowledge about plasticity of the auditory system. Applications of electrophysiologic techniques to hearing aid research and clinical practice are highlighted

OBJECTIVE: To evaluate quality of life issues in patients with laryngeal cancer after treatment with either chemoradiation or total laryngectomy and radiation therapy. METHODS: Forty-nine patients with a history of stage II-IV laryngeal squamous cell carcinoma treated primarily with either chemoradiation or by total laryngectomy with postoperative radiation completed the University of Washington Quality of Life instrument, version 4. Patients were identified on a volunteer basis in an academic university head and neck clinic setting. Each patient completed the above instrument, and statistical analysis was performed by Wilcoxon and chi 2 tests. RESULTS: Instruments were completed by all 49 patients: 15 patients who underwent primary chemoradiation and 34 patients who underwent a total laryngectomy followed by radiation. Domains reported in both treatment groups without significant differences were appearance, activity, recreation, moods, taste, saliva, anxiety, and general questions. However, there were significant differences between the 2 groups in the domains of pain, swallowing, chewing, speech, and shoulder function. The laryngectomy patients reported greater impairment of speech (P = 0.001), and shoulder function (P = 0.018), whereas the chemoradiation patients suffered from greater pain, difficulty swallowing (P = 0.061), and problems chewing (P = 0.027). CONCLUSIONS: Most patients with laryngeal cancer, whether treated primarily with chemoradiation or total laryngectomy, reported excellent functional outcomes and health-related quality of life. Pain, swallowing, chewing, saliva, and shoulder function were recorded as significant factors affecting their daily quality of life

OBJECTIVES/HYPOTHESIS: Since 1998, at our academic, multidisciplinary head and neck cancer treatment center, it has been our policy to treat appropriate patients with locoregionally advanced squamous cell carcinoma of the head and neck (SCCHN) with concomitant radiochemotherapy followed within 6 weeks by planned neck dissection(s). Our objective was to investigate the oncologic efficacy of planned neck dissection, to date, in this patient population with a focus on outcomes in the neck. STUDY DESIGN: Retrospective analysis of a cumulative patient database. METHODS: The medical records of all patients who underwent planned neck dissection(s) after concomitant radiochemotherapy for locoregionally advanced SCCHN at Beth Israel Medical Center and The Institute for Head and Neck Cancer in New York City were reviewed. For each patient, preradiochemotherapy primary and neck stage, postradiochemotherapy/preneck dissection clinical and radiographic neck status, type of neck dissection(s) performed, pathologic status of the neck dissection specimen(s), length of follow-up (after planned neck dissection), disease status at last follow-up, and site(s) of recurrence were recorded. Local, regional, and distant disease control rates were calculated by the Kaplan-Meier method. RESULTS: Fifty-one planned neck dissections were performed on 39 radiochemotherapy patients (12 patients had bilateral operations) between early 1998 and October, 2003. Thirty-two (82%) patients had N2 or greater neck disease, with 29 (74%) having T3/T4 disease at various upper aerodigestive tract primary sites. Patients received an average of 6,700 cGy and 6,000 cGy external beam radiation therapy to primary disease sites and involved cervical lymphatics respectively, concomitant with one of three platinum-based chemotherapy schedules. At a mean follow-up time of 24 (range 8-57) months for the entire study population, there has been only one neck recurrence (N2A neck). No patient with N2B (n = 11), N2C (n = 13, with majority of heminecks staged N2B), or N3 (n = 5) disease has recurred in the neck. No recurrences have occurred in the 41 heminecks (in 33 patients) where modified neck dissection (including 24 selective procedures) was performed despite the presence of residual carcinoma in 13 (32%) of these heminecks on pathologic review. Among all heminecks with residual carcinoma present (n = 18) in the neck dissection specimen, there has been only one neck recurrence. There have been no recurrences in the 26 heminecks (in 19 patients) with incomplete clinical response after radiochemotherapy despite the presence of residual carcinoma in 14 (54%) of these necks on pathologic review. The clinical and radiographic absence of residual disease after radiochemotherapy did not always predict a complete pathologic response. Surgical complications have been limited (1 chyle leak, 1 wound breakdown). CONCLUSIONS: The integration of planned neck dissection into the multidisciplinary management of patients with locoregionally advanced SCCHN is highly effective in controlling cervical metastatic disease. Modified and selective neck dissection procedures can be performed in the majority of patients, regardless of the response in the neck subsequent to concomitant radiochemotherapy. We recommend a planned neck dissection(s) in all patients staged (pretreatment) with N2 or greater neck disease and in select N1 cases.

OBJECTIVES: The sublabial transmaxillary approach to the pterygoid region was a popular one during the Caldwell-Luc, pre-endoscopic era. It was the procedure of choice for management of lesions of the pterygopalatine space, for internal maxillary artery ligation, and for vidian neurectomy. With the introduction of endoscopic instrumentation and techniques, the Caldwell-Luc procedure is rarely performed today. Also, because vidian neurectomy is performed less frequently, and because internal maxillary artery ligation for severe epistaxis has been replaced with transnasal endoscopic sphenopalatine artery ligation, the sublabial transmaxillary route is rarely used. We have found that combining the use of endoscopes via the sublabial approach and the transnasal endoscopic approach is very helpful for management of extreme lateral lesions of the sphenoid sinus, as well as the pterygoid region and the posterior orbit. METHODS: The records of patients who underwent a combined endoscopic transmaxillary-transnasal approach between 1994 and 2002 were reviewed. Indications for the procedure included extreme lateral sphenoid and pterygoid encephalocele (3 patients), pterygoid mucocele (2 patients), orbital apex lesion (2 patients), and pterygopalatine tumor (2 patients). RESULTS: Nine patients underwent the above-mentioned procedure. Wide and comfortable exposure of the involved region was achieved in all cases. Compared with the transnasal approach, the working distance, working comfort, and maneuverability of instruments were significantly enhanced. There were no major complications related to the approach. Because the maxillary wall opening is very small, infraorbital hypoesthesia is very limited and of short duration. CONCLUSIONS: Combining the transmaxillary and transnasal approaches for endoscopic management of pterygoid, lateral sphenoid, and retrobulbar orbit lesions provides excellent exposure and avoids the limited working angle and surgical struggle that may be associated with the use of the transnasal approach alone
