• Article: Zygoma reconstruction.

  ABSTRACT: Ideal reconstruction of the zygoma position is essential in restoring facial width, projection, and symmetry. Reconstruction should be focused on the zygoma's 4 articulations and restoring the vertical and horizontal pillars of the facial skeleton. This article describes the applied surgical anatomy as it relates to zygomatic deformities, surgical approaches, and reconstruction. The basis for diagnosing and classifying zygoma deformities as they relate to severity of injury and associated displacement, comminution, and comorbidities is also discussed. Traditional and contemporary concepts in posttraumatic, postablative, and esthetic reconstruction are also described.

  ABSTRACT: PURPOSE: The purpose of this study was to assess the predictability of sentinel lymph node biopsy (SNB) for oral squamous cell carcinoma (OSCC) when pathologic processing is performed without serial step sectioning. MATERIALS AND METHODS: We prospectively enrolled 36 patients with T1 or T2 cN0 OSCC into this institutional review board-approved prospective cohort study, and they underwent gamma probe-guided SNB in addition to selective neck dissection. The rate of patients with negative SNB results whose neck dissection was also negative for metastasis (negative predictive value) was the primary endpoint. RESULTS: Of the 28 patients whose sentinel lymph nodes were found to be pathologically and clinically node negative by routine hematoxylin-eosin stain and immunohistochemistry, 27 were found to have no other pathologically positive nodes, corresponding to a negative predictive value of 96%. CONCLUSION: The results of this study suggest that SNB performed without the use of thin serial step sectioning may accurately predict neck stage in OSCC.

• Article: Robotic Surgery: A New Approach to Tumors of the Tongue Base, Oropharynx, and Hypopharynx.

  ABSTRACT: Oropharyngeal cancer was traditionally treated with en bloc resection of the tumor via lip-split mandibulotomy approach, often with adjuvant radiation and chemotherapy. In the 1990s, organ-sparing definitive chemoradiation therapy without surgery became the standard of care for oropharyngeal squamous cell carcinoma. Although organ-sparing treatment provided acceptable locoregional disease control with preservation of anatomic organs adjacent to the tumors and less disfiguration from lack of surgical incisions, it often resulted in significant deficits in speech and swallowing. This article reviews a current organ-and-function preserving approach to oropharyngeal carcinoma using the surgical robot.

• Article: Traditional and contemporary surgical approaches to the orbit.

  Michael R Markiewicz, R Bryan Bell
  [show abstract] [hide abstract]
  ABSTRACT: Traditional orbital approaches are nearly a century old and still comprise the foundation of techniques used today. Computer-assisted planning and intraoperative navigation have recently been reported with more prevalence in the literature. The purpose of this article was to review commonly used approaches to the orbit: old and new.
