Does drug-induced sleep endoscopy predict surgical success of limited palatal muscle resection in patients with obstructive sleep apnea?

The aims of this study were to determine the associated factors affecting the success rate of limited palatal muscle resection (LPMR), and to investigate whether drug-induced sleep endoscopy (DISE) could predict the therapeutic response to LPMR in patients with obstructive sleep apnea obstructive sleep apnea (OSA).

Prevention and Management of Complications in Otosclerosis Surgery

Surgical management of otosclerosis is a relatively safe and effective procedure, with a high rate of hearing improvement and a low rate of undesirable outcomes and complications. Many of these potential complications are common to any middle ear surgery, but many are unique to surgery involving the stapes footplate. Preventing complications with stapes surgery and minimizing their impact may be achieved by preparation as well as surgical experience.

Special Anatomic Considerations in Otosclerosis Surgery

The anatomy of the vestibular organs together with considerations of the middle and inner ear anatomy relevant to stapes surgery is discussed. An archival collection of macerated and freshly frozen human temporal bones underwent micro–computed tomography (CT) with subsequent volume-rendering. Three-dimensional (3D) reconstructions and the topographic anatomy of the oval window were considered. Micro-CT and 3D rendering revealed the relationship between the otolith organs and the oval window. Anatomic variations were extensive and included the distance between the footplate and the reconstructed macula margins. A "no-go" zone is suggested for the surgeon to avoid injury during stapes surgery.

Objective.Carcinoma cuniculatum(CC) is a rare variant of squamous cell carcinoma. We describe the clinicopathological findings in a new case.Study Design.Literature review and retrospective study of a case with CC.Results.The clinical and imaging findings of CC are diverse; some cases might be challenging to diagnose accurately by biopsy. This article reports a case of CC that occurred in the retromolar region with involvement of the mandible. The patient was a 39-year-old man. Clinically, the lesion manifested as an ulcerative mass in the mandibular molar region. Imaging results showed that the lesion in the jaw exhibited moth-eaten destruction without obvious expansion of the jaw bone. The postoperative pathological examinations were consistent with CC; additionally, metastases were present in one level II lymph node and one submandibular lymph node. Left soft tissue metastasis and right cervical lymph node metastases were detected after 10 and 27 months after surgery, respectively.Conclusions.CC is a rare epithelial malignant tumor and has variable clinical manifestations. The diagnosis of CC mainly depends upon pathological features. Most patients with CC have a good prognosis; only a small percentage of patients might experience lymph node metastasis.

IntroductionUp to 35% of orbital floor fractures extend to the medial wall. This results in restriction of both abduction and adduction, leading to horizontal diplopia. The greater the defect, the more pronounced the enophthalmos.Aim of the studyThe aim of the study was to determine the influence of concomitant medial wall defects on enophthalmos and diplopia, and the influence of intraoperative revision on the results of surgical reconstruction in patients with orbital floor fracture.Material and methods78 cases of orbital floor fracture, with or without concomitant medial wall defect, were retrospectively analyzed. Reconstruction surgeries were performed in a similar fashion, but with variation in the alloplastic materials used. Careful investigation of the area was performed during the surgery.ResultsPatients with associated medial wall defects had significantly more pronounced enophthalmos than those with isolated floor fracture, with no such difference after the orbital reconstruction. Postoperative vertical diplopia was more common in patients with an associated medial defect.ConclusionsAssociated medial wall defect leads to more severe enophthalmos at presentation. However, if the medial aspect of the orbital wall is revised properly, postoperative outcomes are not inferior to those in cases of isolated floor fracture.

Eosinophilic esophagitis and symptoms possibly related to eosinophilic esophagitis in oral immunotherapy

Food allergy is seen in 2% to 8% of the US population and continues to increase.1–3 Patients with food allergy often have an impaired quality of life and may experience nutritional deficiencies.4,5 Currently, there are no US Food and Drug Administration–approved treatments for food allergy, and it is recommended that patients practice allergen avoidance and carry epinephrine for use in case of severe reaction to unintentional allergen exposure.6 The lifestyle of allergen avoidance presents a challenge and often causes anxiety for patients and caregivers.
