BACKGROUND: Fiberoptic tracheo-bronchoscopy is the most commonly used procedure for percutaneous dilational tracheotomy (PDT). However, PDT can be associated with major complications, including death. Furthermore it is unclear, whether the tracheal ring fractures may contribute to the development of tracheal stenosis after PDT nor whether tracheal ring fractures can be prevented by using a rigid endoscope for this procedure. The purpose of this study was to evaluate the feasibility of and the incidence of complications for PDT using the rigid tracheotomy endoscope (TED)...

BACKGROUND: Although several methods have been described for total lower eyelid reconstruction, it remains as a major challenge in reconstructive surgery. Here, we present a new technique, the Mutaf unequal Z-plasty procedure for reconstruction of defects of the lower eyelid. METHODS: In this technique, 2 skin flaps designed in an unequal Z-plasty manner are used to provide skin coverage. Except for 2 patients whose additional upper eyelid defects were closed with Fricke flap, all patients were reconstructed with Mutaf unequal Z-plasty procedure...

CONCLUSIONS: In this investigation, a large mammal, Rongchang pigs were used to successfully establish a research platform for cochlear implant study on the routine use of it in clinic. OBJECTIVE: The aim of this study was to establish a standard method of cochlear implant in a large mammal-pig. METHODS: Rongchang pigs were selected, then divided into two groups: normal-hearing group (Mitf +/+) and mutation group with hearing loss (Mitf -/-)...

OBJECTIVE: We assessed whether the three-dimensional fluid-attenuated inversion-recovery (3-D FLAIR) and three-dimensional inversion-recovery with real reconstruction (3-D real IR) sequences can be used to detect cochlea endolymphatic hydrops (EHs) in guinea pigs using 3 Tesla magnetic resonance imaging (3T MRI). The results of 3-D real IR imaging were compared with histopathological outcomes. MATERIALS AND METHODS: Fourteen healthy men and women albino guinea pigs were used in this study...

OBJECTIVE: The correlation between the isosorbide-induced decompression effect on the endolymphatic space and plasma osmolality (p-OSM) or plasma arginine vasopressin (p-AVP) was investigated on comparing two different dosages of isosorbide (2.8 and 1.4 g/kg) to elucidate why the decompression effect is delayed with a large dose of isosorbide. MATERIALS AND METHODS: Two experiments were performed using 80 guinea pigs. Experiment 1 was designed to morphologically investigate the sequential influence of the oral intake of 1...

BACKGROUND: Delivery of therapeutic agents directly through the round window (RW) offers promise for treating sensorineural hearing loss. However, hearing loss can result from the surgical approach itself, and the reasons for this are poorly understood. We examined the hearing loss following the 3 major steps involved with the RW approach to access the mouse cochlea: bullostomy, RW puncture, and RW injection. METHODS: Twenty-one adult CBA/J mice underwent bullostomy alone, 10 underwent RW puncture, and 8 underwent RW injection with PBS with 5% glycerol...

BACKGROUND: Surgical Site Infections (SSIs) account for 16-34% of all health-care associated infections. This study aimed to assess the incidence rate of SSIs in children who underwent surgical procedures in an academic children's hospital in Italy. STUDY DESIGN: Prospective cohort study. METHODS: We actively followed-up 0-17 year old children at 30 days of surgical procedures without implants conducted during one index week per quarter, from the second quarter of 2014, to the first quarter of 2016 (8 index weeks in total)...

Objective To compare the Ambu Aura-i with the Air-Q intubating laryngeal airway for fiberoptic-guided tracheal intubation in ear deformity children.Methods Totally 120 children who were scheduled for elective auricular reconstruction surgery requiring general anaesthesia with tracheal intubation were enrolled in this prospective study. They were randomized to receive either the Ambu Aura-i (Aura-i group) or Air-Q (Air-Q group). The time for successful tracheal intubation was assessed. The attempts for successful device insertion, leak pressures, cuff pressures, fiberoptic grade of laryngeal view, time for removal of the device after endotracheal intubation, and complications were recorded...

PURPOSE: Surgical treatment for obstructive sleep apnea (OSA) varies by specialty. Our survey sought to answer 3 principal questions: 1) To which surgical specialists are sleep physicians referring patients for upper airway surgery? 2) Which surgical treatment do sleep specialists find to be most effective in treating OSA? 3) Do sleep medicine physicians believe that maxillomandibular advancement (MMA) is worthwhile to patients who are surgical candidates? MATERIALS AND METHODS: We formulated a cross-sectional survey...

OBJECTIVE: We assessed the surgical results of bipolar release in 31 adult patients with uncorrected congenital muscular torticollis (CMT) and more than 12 months of follow-up. METHODS: Thirty-one patients underwent a bipolar release of the sternocleidomastoid muscle (SCM) and were retrospectively analyzed. The mean follow-up period was 14.9 months (range, 12-30). The mean age at time of surgery was 30.3 years (range, 20-54). Patients were evaluated with a modified Lee's scoring system, cervicomandibular angle (CMA) measurement, and a global satisfaction rating scale using patient self-reporting...

Purpose: Whether, and if so when, a second-ear cochlear implant should be provided to older, unilaterally implanted children is an ongoing clinical question. This study evaluated rate of speech recognition progress for the second implanted ear and with bilateral cochlear implants in older sequentially implanted children and evaluated localization abilities.

BACKGROUND: Shave biopsy may not be able to accurately distinguish squamous cell carcinoma in situ (SCCIS) from invasive squamous cell carcinoma (SCC). Information on the incidence of biopsy-proven SCCIS upstaged to SCC after a more complete histologic examination is limited.

The European Academy of Otology and Neurotology (EAONO) has previously published a consensus document on the definitions and classification of cholesteatoma. It was based on the Delphi consensus methodology involving the broad EAONO membership. At the same time, the Japanese Otological Society (JOS) had been working independently on the "Classification and Staging of Cholesteatoma." EAONO and JOS then decided to collaborate and produce a joint consensus document. The EAONO/JOS joint consensus on "Definitions, Classification and Staging of Middle Ear Cholesteatoma" was formally presented at the 10th International Conference on Cholesteatoma and Ear Surgery in Edinburgh, June 5-8, 2016...

The American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) has published a supplement to this issue of Otolaryngology-Head and Neck Surgery featuring the updated Clinical Practice Guideline: Earwax (Cerumen Impaction). To assist in implementing the guideline recommendations, this article summarizes the rationale, purpose, and key action statements. The 11 recommendations emphasize proper ear hygiene, diagnosis of cerumen impaction, factors that modify management, evaluating the need for intervention, and proper treatment...

Objective This update of the 2008 American Academy of Otolaryngology-Head and Neck Surgery Foundation cerumen impaction clinical practice guideline provides evidence-based recommendations on managing cerumen impaction. Cerumen impaction is defined as an accumulation of cerumen that causes symptoms, prevents assessment of the ear, or both. Changes from the prior guideline include a consumer added to the development group; new evidence (3 guidelines, 5 systematic reviews, and 6 randomized controlled trials); enhanced information on patient education and counseling; a new algorithm to clarify action statement relationships; expanded action statement profiles to explicitly state quality improvement opportunities, confidence in the evidence, intentional vagueness, and differences of opinion; an enhanced external review process to include public comment and journal peer review; and 3 new key action statements on managing cerumen impaction that focus on primary prevention, contraindicated intervention, and referral and coordination of care...
