The complex architecture of the auricle makes it one of the most challenging structures for the reconstructive surgeon to re-create. Overlying the ear's unique cartilage framework are layers of varied soft tissues forming a three-dimensional organ, which is distinctively positioned on the head. Arguably, the most challenging auricle to reconstruct is third-degree microtia due to a near-total absence of native tissue and a need for lifelong durability of the reconstruction. Many methods of reconstruction have been studied; autogenous costal cartilage reconstruction has been one of the more traditional methods, with favorable long-term results reported by several surgeons. However, this technique requires tremendous artistic and technical skill on the part of the surgeon-sculptor to construct a realistic-appearing ear. High-density porous polyethylene (Medpor) is a stable, alloplastic implant that can integrate with host tissues, is resistant to infection, and has been successfully applied to reconstruction of the head and neck. For auricular reconstruction, Medpor--enveloped in a temporoparietal fascial flap with full-thickness skin graft coverage--is a durable and aesthetically gratifying alternative in microtic patients. This alternative surgical technique reduces surgical time and morbidity, standardizes results among surgeons, and facilitates an aesthetic, natural-appearing reconstruction of the auricle

BACKGROUND: Several unique complications of thyroidectomy exist because of its regional anatomy; they are well studied and reported. A majority of thyroidectomy patients report vague upper aerodigestive tract complaints. Despite this, no formal assessment of the integrity of the internal branch of the superior laryngeal nerve after thyroidectomy exists in the literature. METHODS: Thirty three patients undergoing thyroidectomy were prospectively evaluated with preoperative and postoperative laryngopharyngeal sensory testing. RESULTS: Preoperatively, 16 patients (49%) reported dysphagia, and 19 (58%) complained of globus sensation. Postoperatively, 24 (73%) patients complained of dysphagia, and 25 (76%) reported globus sensation. Preoperative sensory testing showed a mean sensory threshold of 2.79 +/- 0.51 mm Hg. The mean change in thresholds postoperatively was trivial (0.07 +/- 0.29 mm Hg), and did not differ significantly from zero (p = .19). CONCLUSIONS: Although most patients report significant difficulty swallowing after thyroidectomy, the sensory nerve to the laryngopharynx remains intact and is not at risk during thyroid surgery

OBJECTIVE: To describe changes in disease-specific and global quality of life (QOL) for children with recurrent or chronic tonsillitis at 6 months and 1 year after tonsillectomy using two validated instruments, the Tonsil and Adenoid Health Status Instrument (TAHSI) and the Child Health Questionaire-PF28 (CHQ-PF28). STUDY DESIGN AND SETTING: A multicenter, prospective observational outcomes study. RESULTS: Ninety-two children, mean age (SD) 10.6 (3.4) years, enrolled with follow-up available for 58 children at 6 months and 38 children at 1 year. The children showed significant improvements in all subscales of the TAHSI including airway and breathing, infection, health care utilization, cost of care, eating and swallowing (all P < 0.001), and behavior (P = 0.01). Significant improvements were also found on several subscales of the CHQ-PF28, such as general health perceptions, physical functioning, parental impact, and family activities (all P < 0.001). CONCLUSION/SIGNIFICANCE: This uncontrolled study provides prospective evidence of improved disease-specific and global QOL in children after tonsillectomy

OBJECTIVE: To describe changes in disease-specific and global quality of life (QOL) for adults with recurrent or chronic tonsillitis at 6 months and 1 year after tonsillectomy using two instruments: the Tonsil and Adenoid Health Status Instrument (TAHSI) and the SF-12 Health Survey (12-item short form of SF-36 Health Survey). STUDY DESIGN AND SETTING: Multicenter, prospective observational outcomes study. RESULTS: Seventy-two adults, mean age 28.0 years (SD 7.2 years), were enrolled with follow-up available for 42 adults at 6 months and for 40 adults at 1 year. Patients showed significant improvements in all six subscales of the TAHSI: airway and breathing, infection, health care utilization, cost of care, eating and swallowing, and behavior (all P < 0.0001). Significant improvements were also found in the physical functioning subscale of the SF-12 at 1 year. CONCLUSION: After tonsillectomy for recurrent and chronic tonsillitis, we found large improvements in disease-specific and global QOL. SIGNIFICANCE: Most prior studies on tonsillectomy for recurrent tonsillitis have assessed only the frequency of infections as an outcome measure. This study describes the changes in QOL measured in our cohort of reporting adults after tonsillectomy for chronic or recurrent tonsillitis. This study provides prospective evidence of the effectiveness of tonsillectomy on adult QOL

A variety of inflammatory lesions and tumors can present within the lacrimal gland. Given the inconsistency in the preoperative differentiation of malignant from benign tumors, complete surgical resection and histological identification remain the only means for a correct diagnosis. Lacrimal tumors such as pleomorphic adenoma have a high rate of recurrence and can undergo malignant transformation if they are not completely removed. Lacrimal gland tumors should undergo complete excision (with preservation of its capsule) without a primary incisional biopsy. These excisions can be facilitated through a lateral orbitotomy, which can offer the surgeon an exceptional approach with optimal exposure with or without the use of bone window

In previous works, the authors showed that using robot-assisted steerable electrode array insertions can significantly reduce the insertion forces compared to non-steerable electrode arrays. In addition to steering the electrode array, it is possible to change its angle of approach with respect to the scala tympani. This paper focuses on determining the relevance of changing the angle of approach of the electrode array by comparing steerable electrode array insertions using a two Degrees-of-Freedom (DoF) robot versus a four DoF robot. Optimal insertion path planning strategies are presented for both two and four DoF insertions. Simulation results and experiments show that the four DoF insertions can improve over two DoF insertions. Moreover, changing the angle of approach can further reduce the insertion forces. The simulation results also provide the workspace requirements for designing a custom parallel robot for robot-assisted cochlear implant surgery

The severity of deafness can obscure the presence of other disabilities that may accompany genetic anomalies, such as occur in Alport and Usher syndromes. Recent advances in genetics have heightened attention to various disabilities and dysfunctions that may coexist with deafness. Failure to recognize these additional disabilities when they occur can misguide educational planning; may open the afflicted deaf person to failure to identify, diagnose, and manage potentially serious health conditions; and in some instances may even lead to loss of life. Of the many genetic conditions that have been identified, a few examples are cited to illustrate the need to inform parents, educators, and other caregivers about the importance of obtaining genetic information.
