RESUMEN

The alar-columellar relationship is an important concept for the rhinoplasty surgeon to master. The alar rim in particular is a critical component of the nasal tip, contributing to both overall symmetry and proportion of the nasal base. The retracted ala creates a displeasing aesthetic to the tip complex, distorts the nostril openings, and may have functional implications of the external nasal valve. While alar retraction can occur naturally or as the result of trauma, the majority of cases are post-surgical in nature. Many techniques have been described for correction of alar retraction, most of which require open rhinoplasty and many fail to add the soft tissue within the vestibule necessary to properly lower the alar margin. Herein, we present our experience with the auricular chondrocutaneous composite graft-a simple, reliable, and effective technique to correct moderate to severe alar retraction via either open or endonasal rhinoplasty.

RESUMEN

Irregularities of the nasal dorsum or tip are a potential risk after rhinoplasty. Patients with thin skin are considered to be at a higher risk of these irregularities. Different materials and grafts to address areas that may result in a contour irregularity postoperatively include diced or crushed cartilage, temporalis fascia, fascia lata, and AlloDerm. We describe a new graft, the supracrural ligament graft, which can be used to camouflage or add bulk during primary rhinoplasty. The graft is harvested easily during the initial exposure and does not require additional surgical sites or extra dissection. In this research, we described the use of the supracrural ligament graft in 49 patients. We found the average graft size to be 0.6 × 0.4 cm. The graft was used in the following locations: nasal tip (49%), radix (40%), and nasal dorsum (10%). No complications were seen using the graft in any of the 49 patients. In conclusion, the supracrural ligament graft is a safe, simple, and effective camouflage graft for commonly encountered irregularities in rhinoplasty. Common areas of use include the nasal dorsum and nasal tip. Routine harvest of this graft may obviate the need to use either additional grafting material or an additional surgical site to help camouflage areas of concern in thin skin patients.

RESUMEN

PURPOSE: To report our experience of a sequence of events that resulted in an iatrogenic cholesteatoma originating from the external auditory canal (EAC) years after tympanoplasty that had included a tympanomeatal flap. METHODS: Data on the presentation and pathogenesis of iatrogenic cholesteatomas arising from misplaced tympanomeatal flaps during tympanoplasty without mastoidectomy were retrieved from the patients' medical records and analyzed. RESULTS: Five patients were identified with cholesteatomas involving the EAC. They all had recurrent ear infections and varying degrees of conductive hearing loss. Each patient's past surgical history included one or more tympanoplasties in which an ipsilateral tympanomeatal flap had been raised. None had undergone a mastoidectomy. Two patients presented with small cholesteatomas that had developed over an average of 6.5 years after surgery. Three patients had large cholesteatomas that had developed over an average of 33.7 years after surgery. Clinical presentations and imaging studies suggested a misplaced tympanomeatal flap as the most likely source of cholesteatoma. CONCLUSION: Tympanomeatal flap misplacement may cause iatrogenic cholesteatoma formation originating from the EAC during tympanoplasty even without mastoidectomy. These cholesteatomas can grow substantially before becoming symptomatic as they extend to and through the mastoid. They may not affect the sound conduction system until late in the course of the disease. Meticulous replacement of tympanomeatal flaps and exercising a high index of suspicion postoperatively can reduce the incidence of this complication.

RESUMEN

An ideal nasal osteotomy should deliver precise, predictable, and reproducible cosmetic and functional results while minimizing soft-tissue trauma and postoperative complications. In addition to closing an open roof deformity after hump reduction, other common indications for osteotomies include the crooked nose and a wide bony vault. The literature has reported numerous and diverse osteotomy techniques as well as differences in timing of osteotomies. Each has its own merits and indications, and its proponents. In this article, we review the anatomy and nomenclature relating to osteotomies. We review the locations and paths of the osteotomies-lateral, intermediate, medial, and superior/transverse. We consider the percutaneous and endonasal approaches, as well as timing of osteotomies and other considerations. We also discuss technical considerations in the selection of instrumentation for osteotomies.

RESUMEN

Nasal obstruction is a common presenting complaint, with many possible etiologies. Herein, we provide an introductory anatomic description, clinical relevance, and proposed nomenclature for an underappreciated soft tissue focus in the nasal vestibule-the nasal vestibular body (NVB)-that can contribute to nasal obstruction in a subset of patients. This is a small mound of dynamic soft tissue in the lateral aspect of the internal nasal valve, situated inferior and anterior to the head of the inferior turbinate that can be missed on routine examination for many salient reasons. In well-selected patients, whose symptoms of nasal obstruction may in part be secondary to the presence of this soft tissue focus, directed testing and tissue reduction can be performed.

RESUMEN

The objective of the study is to present a large case series of parapharyngeal space tumors (PPST) and the most comprehensive literature review of tumor histopathologic distribution. The study was designed as internal case series and full Pubmed/MEDLINE electronic database review in a tertiary academic medical center. Tumor histopathology and patient demographics were obtained from a comprehensive Pubmed/MEDLINE database review, as well from an internal case series of 117 patients referred to our center between 1993 and 2013. Main outcome and measures of the study were to define the age, gender, and histopathology of PPST within a large internal case series and among the current body of published literature, and to propose a diagnostic and treatment algorithm for these tumors. Our cohort included 117 cases, 58 females and 59 males, with benign tumors comprising 85 % (n = 99) and malignant tumors 15 % (n = 18). A systematic review of published literature from 1963 to the present revealed 37 case series, and when combined with our present series, yielded a total of 2160 cases. Benign tumors are most common (78.8 %), with tumors of salivary gland (44.4 %), neural (34.4 %), and vascular (2.64 %) origin representing the largest subtypes. Pleomorphic adenomas (30.9 %), paragangliomas (13.1 %), and schwannomas (12.3 %) comprised the majority of all cases. Due to their rarity, data regarding the histopathologic distribution of PPST is scarce. We provide one of the largest case series and the most comprehensive review of these tumors in the literature to date, and offer our algorithm for evaluation and treatment.

RESUMEN

BACKGROUND: Tranexamic acid (TXA) is an antifibrinolytic that has become widely used in aesthetic facial plastic surgery, although its efficacy has not been well investigated. OBJECTIVES: To evaluate the existing evidence for use of TXA in aesthetic facial plastic surgery, highlighting routes of administration, dosing, surgical applications, and clinical outcomes. METHODS: Systematic review of primary literature evaluating TXA in aesthetic facial plastic surgery. RESULTS: Eleven studies met inclusion criteria: 8 prospective randomized controlled trials, 2 retrospective case series/cohort studies, and 1 clinical opinion. Six studies evaluated TXA in rhinoplasty, 4 in rhytidectomy, and 1 in blepharoplasty. Significant reductions in intraoperative blood loss were found in 5 rhinoplasty studies. Three rhinoplasty and 2 rhytidectomy studies found significantly reduced postoperative edema and ecchymosis. One rhinoplasty and 1 rhytidectomy study reported reduced operative time and time to achieve hemostasis. One rhytidectomy study reported reduced postoperative drain output and faster time to drain removal. No studies reported an adverse outcome directly related to TXA. CONCLUSIONS: Existing literature investigating TXA in aesthetic facial plastic surgery is sparse with varying levels of evidence and heterogeneous data. Literature suggests systemic TXA reduces intraoperative blood loss during rhinoplasty, although the clinical significance of this blood loss reduction is unclear. TXA may also reduce postoperative edema and/or ecchymosis in rhytidectomy and rhinoplasty, although the lack of validated grading scales yields insufficient evidence to support this claim. Topical and subcutaneously injected TXA are emerging administration routes in rhytidectomy, with evidence suggesting TXA mixed with tumescent may reduce postoperative drain output, thereby expediting drain removal.

RESUMEN

The aging neck is one of the most common motivations for patients to seek aesthetic rejuvenation. Increasingly, patients are desiring less invasive aesthetic treatments with less morbidity and downtime. Percutaneous radiofrequency technologies have been recently introduced for cervical rejuvenation. These technologies safely and effectively apply energy directly into the subdermal space, targeting the upper dermal collagen network, the deeper fascial layer, and the fibrofatty septum that anchors the dermis to the deep fascia. Significant skin tightening and fat reduction have been reported with these technologies, beyond that which is currently achievable with other minimally invasive energy-based technologies.

RESUMEN

PURPOSE OF REVIEW: To examine the recent literature on extracorporeal septoplasty. RECENT FINDINGS: The literature suggests that extracorporeal septoplasty is an effective approach for both functional and cosmetic treatment of moderate to severe deformities of the caudal and dorsal septum. The procedure can be performed via an endonasal or external approach based on the nature of the deformity and the experience of the surgeon, although recent literature highlights various advantages of an external approach. The use of polydioxanone foil as a scaffold for septal reconstruction is widely accepted, and can enhance the technical performance of this technique. Although reported complication rates are low, tip deprojection and rotation have been observed in cases where extracorporeal septoplasty is performed without simultaneous rhinoplasty. SUMMARY: Extracorporeal septoplasty is a useful technique in the armamentarium of surgeons addressing deviations of the dorsal and caudal septum.

RESUMEN

OBJECTIVE: To survey patients following sinonasal surgery regarding postoperative pain and opioid use. STUDY DESIGN: Patients were surveyed for 4 days following sinus and/or nasal surgery regarding their pain level and use of prescribed opioids. SETTING: Four academic medical centers and 1 private practice institution. SUBJECTS: Consecutive adult patients undergoing sinonasal surgery. RESULTS: A total of 219 subjects met criteria and were included for analysis; 134 patients (61%) took 5 or fewer combination oxycodone (5-mg) and acetaminophen (325-mg) tablets in the first 3 postoperative days, and 196 patients (89.5%) took fewer than 15. Fifty-one patients (23%) consumed no opioid pain medication. Opioid consumption was positively correlated with postoperative pain ( R2 = 0.2, P < .01) but was not correlated with the use of acetaminophen ( R2 = 0.002, P = .48). No significant difference in postoperative pain or opioid consumption was seen with respect to age, sex, specific procedures performed, postoperative steroids, or smoking history. Current smokers reported higher average pain than nonsmokers ( P < .001) and also required more postoperative opioids ( P = .02). CONCLUSIONS: An evidence-based approach to postoperative pain control following sinonasal surgery that reduces the number of unused and potentially diverted opioids is needed. The current study suggests that 15 combination oxycodone (5-mg) and acetaminophen (325-mg) tablets provide sufficient pain control for 90% of patients in the immediate postoperative period following sinonasal surgery, irrespective of the specific procedures performed, use of acetaminophen, or use of systemic steroids. Smoking status may help surgeons predict which patients will require larger opioid prescriptions.

RESUMEN

Objective To evaluate the effect of anatomy-specific virtual reality (VR) surgical rehearsal on surgeon confidence and temporal bone dissection performance. Study Design Prospective pre- and poststudy of a novel virtual surgical rehearsal platform. Setting Academic otolaryngology-head and neck surgery residency training programs. Subjects and Methods Sixteen otolaryngology-head and neck surgery residents from 2 North American training institutions were recruited. Surveys were administered to assess subjects' baseline confidence in performing 12 subtasks of cortical mastoidectomy with facial recess. A cadaver temporal bone was randomly assigned to each subject. Cadaver specimens were scanned with a clinical computed tomography protocol, allowing the creation of anatomy-specific models for use in a VR surgical rehearsal platform. Subjects then rehearsed a virtual mastoidectomy on data sets derived from their specimens. Surgical confidence surveys were administered again. Subjects then dissected assigned cadaver specimens, which were blindly graded with a modified Welling scale. A final survey assessed the perceived utility of rehearsal on dissection performance. Results Of 16 subjects, 14 (87.5%) reported a significant increase in overall confidence after conducting an anatomy-specific VR rehearsal. A significant correlation existed between perceived utility of rehearsal and confidence improvement. The effect of rehearsal on confidence was dependent on trainee experience and the inherent difficulty of the surgical subtask. Postrehearsal confidence correlated strongly with graded dissection performance. Subjects rated anatomy-specific rehearsal as having a moderate to high contribution to their dissection performance. Conclusion Anatomy-specific virtual rehearsal improves surgeon confidence in performing mastoid dissection, dependent on surgeon experience and task difficulty. The subjective confidence gained through rehearsal correlates positively with subsequent objective dissection performance.

RESUMEN

Importance: A method to optimize imaging of cholesteatoma by combining the strengths of available modalities will improve diagnostic accuracy and help to target treatment. Objective: To assess whether fusing Periodically Rotated Overlapping Parallel Lines With Enhanced Reconstruction (PROPELLER) diffusion-weighted magnetic resonance imaging (DW-MRI) with corresponding temporal bone computed tomography (CT) images could increase cholesteatoma diagnostic and localization accuracy across 6 distinct anatomical regions of the temporal bone. Design, Setting, and Participants: Case series and preliminary technology evaluation of adults with preoperative temporal bone CT and PROPELLER DW-MRI scans who underwent surgery for clinically suggested cholesteatoma at a tertiary academic hospital. When cholesteatoma was encountered surgically, the precise location was recorded in a diagram of the middle ear and mastoid. For each patient, the 3 image data sets (CT, PROPELLER DW-MRI, and CT-MRI fusion) were reviewed in random order for the presence or absence of cholesteatoma by an investigator blinded to operative findings. Main Outcomes and Measures: If cholesteatoma was deemed present on review of each imaging modality, the location of the lesion was mapped presumptively. Image analysis was then compared with surgical findings. Results: Twelve adults (5 women and 7 men; median [range] age, 45.5 [19-77] years) were included. The use of CT-MRI fusion had greater diagnostic sensitivity (0.88 vs 0.75), positive predictive value (0.88 vs 0.86), and negative predictive value (0.75 vs 0.60) than PROPELLER DW-MRI alone. Image fusion also showed increased overall localization accuracy when stratified across 6 distinct anatomical regions of the temporal bone (localization sensitivity and specificity, 0.76 and 0.98 for CT-MRI fusion vs 0.58 and 0.98 for PROPELLER DW-MRI). For PROPELLER DW-MRI, there were 15 true-positive, 45 true-negative, 1 false-positive, and 11 false-negative results; overall accuracy was 0.83. For CT-MRI fusion, there were 20 true-positive, 45 true-negative, 1 false-positive, and 6 false-negative results; overall accuracy was 0.90. Conclusions and Relevance: The poor anatomical spatial resolution of DW-MRI makes precise localization of cholesteatoma within the middle ear and mastoid a diagnostic challenge. This study suggests that the bony anatomic detail obtained via CT coupled with the excellent sensitivity and specificity of PROPELLER DW-MRI for cholesteatoma can improve both preoperative identification and localization of disease over DW-MRI alone.

RESUMEN

OBJECTIVE: To collect data on skull base surgery training experiences and practice patterns of otolaryngologists that recently completed fellowship training. DESIGN: A 24-item survey was disseminated to physicians who completed otolaryngology fellowships in rhinology, head and neck oncology, or neurotology between 2010 and 2014. RESULTS: During a typical year, 50% of rhinologists performed more than 20 endoscopic anterior skull base cases, 83% performed fewer than 20 open cases, and were more confident performing advanced transplanum (p = 0.02) and transclival (p = 0.03) endoscopic approaches than head and neck surgeons. Head and neck surgeons performed fewer than 20 endoscopic and fewer than 20 open cases in 100% of respondents and were more confident with open approaches than rhinologists (p = 0.02). Neurotologists performed more than 20 lateral skull base cases in 45% of respondents during a typical year, fewer than 20 endoscopic ear cases in 95%, and were very comfortable performing lateral skull base approaches. CONCLUSION: Many recent otolaryngology fellowship graduates are integrating skull base surgery into their practices. Respondents reported high confidence levels performing a range of cranial base approaches. Exposure to endoscopic ear techniques is minimal in neurotology training, and rhinology training appears to offer increased exposure to skull base surgery compared with head and neck training.
