Review of retropharyngeal and parapharyngeal nodal metastasis of papillary thyroid carcinoma.

BACKGROUND: Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer. In rare instances, PTC has metastasized to the retropharyngeal and parapharyngeal nodes. This is hypothesized to occur due to an aberrant lymphatic channel or via retrograde lymphatic flow following previous neck dissection. METHODS: A literature search was conducted with keywords "parapharyngeal," "retropharyngeal," and "papillary thyroid carcinoma." RESULTS: 46 articles were identified for a total of 135 cases. The most common presenting symptom was lymphadenopathy followed by pharyngeal mass and dyspnea. 38.03 % of patients were asymptomatic. Of cases including initial treatment history, 94.44 % had a history of neck dissection. The transcervical approach was the most utilized to resect the tumors, although in recent years trans-oral robotic surgery (TORS) has also been used. CONCLUSION: PTC metastatic to the retropharyngeal and parapharyngeal nodes is a rare occurrence that can be difficult to diagnose due its indolent nature.

Delayed skin grafting protocol following Integra™ application for non-radiated scalp reconstruction for decreased wound depth and improved contour.

The clinical use of Integra™ has expanded to include scalp reconstruction since its FDA approval in 1996. Integra™, or dermal regeneration template, can be utilized in patients who are elderly with multiple medical comorbidities. Well-established Integra™ techniques utilize skin grafting 1-2 weeks following evidence of template vascularity. Most studies show the time to graft placement as <30 days, with almost all <52 days. No single article proposes a time frame for applying STSG after neodermis regeneration. Therefore, we aimed to describe our protocol to define a time frame for delaying scalp reconstruction with STSG following dermal regeneration. Over the last several years, the senior author has utilized a delayed reconstruction with skin grafting method where-in Integra™ is applied to either debrided bone or exposed pericranium in selected patients, and allowed to mature for ~6 weeks before performing skin grafting. The results have been predictable, reproducible, and have yielded high levels of patient and provider satisfaction due to the improved contour cosmesis. In this pictorial essay, the authors' novel protocol is detailed.

Examining Trends in Implantable Arterial Doppler Usage Among North American Head and Neck Microsurgeons: A Survey Study.

BACKGROUND: There are variations in implantable arterial Doppler usage for microvascular free tissue monitoring among North American surgeons. Identifying utilization trends among the microvascular community may elucidate practice patterns that may be useful in determining protocols. Furthermore, study of this information may yield novel and unique applications in other disciplines such as vascular surgery. METHODS: Electronically disseminated survey study shared with a large database of North American head and neck microsurgeons. RESULTS: Seventy four percent of respondents use the implantable arterial Doppler; 69% report use in all cases. Ninety five percent remove the Doppler by the seventh postoperative day. All respondents felt that the Doppler did not impede care progression. Any implication of flap compromise was followed with a clinical assessment in 100% of respondents. If viable, 89% would continue monitoring after clinical examination, while 11% would take the patient for exploration regardless of clinical examination. CONCLUSIONS: The efficacy of the implantable arterial Doppler has been established in the literature and is supported by the results of this study. Further investigation is required to establish a consensus on use guidelines. The implantable Doppler is more often used in conjunction with rather than substitution for clinical examination.

Impact of smoking on donor site following rectus flap harvest for head and neck reconstruction.

OBJECTIVES: The rectus abdominis myocutaneous free flap has been widely used as a reconstructive option in head and neck reconstruction with great success. Challenging the popular assumption, this study sought to examine the effects of smoking on donor site complications in this population. METHODS: Multi-institution retrospective study of 103 patients (50 active smokers, 28 former and 25 never smoked). RESULTS: Overall complication rate was 14.5 %. Hernia rate 4.8 %, evisceration 0 %, dehiscence 2.9 %, infection 6.7 %. Smoking history did not significantlly influence complication rates (chi square test, p = 0.33). Abdominal wall closure technique also did not influence the complication rate (chi square test, p = 0.58). CONCLUSIONS: The rectus abdomonis myocutaneous free flap has an acceptable complication rate that does not appear to be influenced by smoking history. While patients should be counseled regarding smoking cessation, smoking habits should not delay treatment nor obviate consideration of rectus flap utilization.

Intraoral nasolabial flap for lower lip augmentation following post-radiation contracture.

The nasolabial flap (NLF) has been reported extensively for reconstruction of various intraoral and extraoral defects resulting from trauma or ablative surgery. However, it has not been described for post-radiation lip augmentation. Herein, we present the case of a 74-year-old female who previously underwent a subtotal glossectomy and free flap reconstruction followed by radiotherapy. While oncologically the patient did well, she developed a significant lower lip contracture which compromised oral intake, denture placement, lip excursion, and psychosocial well-being. The patient underwent release of the scar contracture and a NLF was utilized intraorally to act as a spacer between the gingiva and inner lip mucosa to augment the soft tissue deficit. The patient went on to regain oral intake and placement of her dentures, while reporting significant satisfaction with the post-procedural benefits.

Surgical Treatment of a Bilateral Mandibular Fracture in a Patient with Osteogenesis Imperfecta Type III.

Osteogenesis imperfecta is a group of genetic disorders affecting skeletal and connective tissue that commonly presents with a history of multiple fractures. In particular, Osteogenesis imperfecta type III is associated with severe bone deformities, specifically in the mandible with deformities such as mandibular overjet and cross-bite. We report a case of a bilateral mandibular fracture in a young adult diagnosed with Osteogenesis imperfecta type III, managed surgically with open reduction internal fixation.
