RESUMEN
Background: To describe a novel technique to modify the proportional length of the anterior-to-posterior digastric muscles to improve neck aesthetics. Objective: To provide an objective measure to quantify neck rejuvenation and a novel technique to adjust the digastric ratio. Design: We retrospectively compared 52 patients who had neck rejuvenation with or without digastric manipulation. Preoperative and postoperative images were analyzed and compared with computer software using a novel analysis technique to measure the digastric ratio and neck height. Distances between the menton, cervical point (CP), and gonion were measured. Results: The anterior-to-posterior digastric ratio improved an average of 26.5% (p < 0.01) in the new technique group, 15.9% in the control group. Distance of the CP to the inferior edge of the mandible decreased an average of 13.9% using the new technique. Conclusion: The ratio of anterior-to-posterior digastric muscle appears to improve as well as the neck height with manipulation of the digastric muscles.
RESUMEN
Background: Many methods have been described to reduce postoperative ecchymosis in rhinoplasty with tranexamic acid (TXA) remaining controversial. TXA remains a consideration for surgeons, however, may have serious side effects, including seizures, blood clots, and vision changes. Methods: A prospective study of primary rhinoplasty patients was performed from March 2019 to June 2019. TXA was used in 50 patients and postoperative ecchymosis was compared with 50 control patients. Adobe Photoshop was used to quantitate postoperative ecchymosis using multiple objective color scales. Results: One hundred subjects were enrolled in the study. Eighty-four females and 16 males were included. Photographs were taken on postoperative day 7. There were no significant differences among any of the Red, Green, Blue (RGB) and L*a*b* color subgroups with p > 0.05. There were no adverse events with TXA. Conclusions: In this study, TXA did not reduce postoperative ecchymosis in rhinoplasty when used both through intravenous and intraoperative injections.

The revision rhinoplasty presents many unique challenges to the facial plastic surgeon. While many cases will require a full revision in the operating room, there are several isolated deformities which may be repaired in the office via an endonasal approach. This provides many benefits to the patient and surgeon including decreased cost, shorter recovery time, avoidance of general anesthesia, and less discomfort. It is critical to identify defects appropriate for endonasal repair, establish clear expectations with the patient, and work within one's skill set and level of experience. The surgeon who can comfortably navigate both open and endonasal techniques can offer their patients a comprehensive set of solutions for revision rhinoplasty. In this article we outline the defects amenable to this type of repair as well as technical considerations for each defect addressed. We hope it serves as a useful framework for the range of deformities the rhinoplasty surgeon may take on for in-office repair.

The aging face is a popular topic in modern medicine. To understand and treat unwanted signs of aging, it is imperative to understand the biological and physical causes and contributing factors to facial aging, preventative measures to avoid advanced facial aging, and current treatment options. Changes to the human face are progressive with time; however, there are many methods, both surgical and nonsurgical, to reduce the stigmata of aging and provide patients with the appearance they desire. The process of aging is discussed in this article, as well as the multiple treatment options, both surgical and nonsurgical.

INTRODUCTION: The endoscopic brow lift technique relies on brow mobilization and often soft fixation to the underlying calvarium. While the endoscopic brow lift has been used safely, there are anecdotal reports of cerebrospinal fluid leak. We sought to measure calvarial thickness to improve the safety of cranial fixation. METHODS: A retrospective review was performed of T2 weighted MRIs of the face of 28 patients. Calvarial thickness was measured on 10 coronal planes, from 3 centimeters (cm) anterior to 6 cm posterior to coronal suture. Fifteen points were measured on each coronal plane, starting in the midline and extending laterally for 7 cm. There were a total of 150 calvarial measurements per patient, covering the surface area used in endoscopic brow lifts. Statistical comparison was performed using analysis of variance. RESULTS: Cranial thickness ranged from 1.1 to 13.6mm, with a mean of 6.1mm. The skull was thickest 2-4 cm posterior to the coronal suture, and thinnest 1cm anterior to the coronal suture. The cranium thins as it extends laterally, with an average thickness of 5.0mm at seven centimeters from midline. Average skull thickness for males was 5.96 versus 6.16 in females. There was no relationship between age and skull thickness. CONCLUSION: Cranial thickness increases medially and posteriorly, and is larger for females compared with their male counterparts. Given the risk of CSF leak, surgeons need to be aware of how cranial thickness varies by location along the skull.

IMPORTANCE: The effect of different rhinoplasty maneuvers on alar retraction remains to be elucidated. OBJECTIVE: To determine the etiology and treatment of alar retraction based on a series of specific rhinoplasty maneuvers. DESIGN: Retrospective review of a single surgeon's rhinoplasty digital photo database, examining preoperative alar retraction from January 1, 2002, to December 31, 2005, in 520 patients. Patients with more than 1 mm of alar retraction on preoperative photographs were identified. Postoperative photographs were examined to determine the effect of specific rhinoplasty maneuvers on the position of the alar margin; these maneuvers included cephalic trim, cephalic positioning of the lower lateral cartilage, composite grafts, alar rim grafts, alar batten grafts, and overlay of the lower lateral cartilage. SETTING: Tertiary care academic health center. PARTICIPANTS: Forty-five patients with alar retraction met inclusion criteria, resulting in 63 nasal halves with alar retraction. MAIN OUTCOMES AND MEASURES: Intraoperative findings, postoperative results. RESULTS: Forty-seven percent of the patients (n = 21) had prior surgery; 47% also had cephalically positioned lower lateral cartilages. Among patients with less than 4 mm of cartilage width at the outset, 46% of those who received supportive grafts achieved target correction vs only 7% for patients who did not undergo supportive cartilage grafting. In patients who underwent more than 4 mm of cephalic trim, those who received supportive grafts achieved 46% of target correction vs 11% among those who did not. Ninety-five percent of composite grafts, 69% of alar strut grafts, 47% of alar rim grafts, 43% of vertical lobule division, and 12% of alar batten grafts achieved their target correction values. CONCLUSIONS AND RELEVANCE: Alar retraction is a highly complex problem. It can be seen de novo and is associated with cephalically positioned lower lateral cartilages. Structurally supportive grafting-including composite grafts, alar strut grafts, alar rim grafts, vertical lobule division, and alar batten grafts-can improve alar retraction. LEVEL OF EVIDENCE: 4.

Hematomas, pseudocysts, and seromas are all part of the differential diagnosis of auricular swellings. Seromas are benign collections of serous fluid that have a tendency to recur. The fluid accumulates in the space between the dermis and perichondrium of the ear. We describe what we believe is the first case of spontaneous bilateral auricular seromas to be reported in the literature. One of the seromas resolved in 4 weeks without treatment, and the other resolved with incision and drainage. It is important for physicians to be aware of auricular seromas when considering the differential diagnosis of an auricular swelling, and to understand the various treatment options.

A significant proportion of the population has nasal septal deviation of varying degrees. Recent reports of such deviation occurring at younger ages suggest a congenital etiology. To the best of our knowledge, no previous clinical studies have compared the septal deviation of adult and pediatric populations with a uniform measure that focuses on the degree of deviation. We retrospectively analyzed computed tomography (CT) and magnetic resonance imaging (MRI) scans obtained from 81 patients who had undergone head and neck imaging for a variety of reasons. These subjects were divided into four age groups: younger than 4 months; 4 months to less than 5 years; 5 to 15 years; and more than 15 years. We used a measure of tortuosity to examine and compare nasal septal deviation among the different age groups. The tortuosity of the septum was measured at four precise points along the length of the septum on thin-section sinus CT and MRI. Tortuosity was defined as the ratio of the "actual" length of the septum to the "ideal" length of the septum, which was defined as the length of a straight line drawn from the superior to the inferior aspect of the septum. We found that subjects younger than 5 years of age exhibited significantly less tortuosity (p ≤ 0.017459) than did the older children and the adults. Therefore, we conclude that nasal septal deviation occurs at a higher frequency in older children and in adults when calculations of tortuosity are used as a measure. Our data may suggest that a noncongenital etiology is responsible for nasal septal deviation. However, given that the growth of the septum continues throughout childhood, our results do not preclude the possibility of a genetic predisposition to the later development of a deviated nasal septum.

BACKGROUND: There is little research which determines whether septoplasty affects nasal projection. OBJECTIVES: To assess the effect of various septoplasty (submucous resection, SMR) techniques on nasal tip projection in a fresh cadaver model. METHODS: The nasal tip projection was measured on 6 fresh cadaver heads and compared postoperatively after a sequence of submucous septoplasty maneuvers. Five different septoplasty techniques were performed in the same sequence on each cadaver. After each technique, measurements were performed. RESULTS: Removal of a central square piece of quadrangular cartilage resulted in a loss of projection in 3 in 6 (50%) heads, with average loss of 7.76%. Removal of additional cartilage along the bony cartilaginous junction resulted in no loss of projection. Removing more septum along the floor resulted caused a change loss in nasal projection in 1 in 6 (17%) cadavers. Removing the remaining septum, except for the L-strut resulted in a loss of projection in 2 in 6 (33%) heads with an average percent change in tip projection of 9.08%. Swinging door technique resulted in a loss of projection in 1 cadaver (17%), with loss of 6.25%. All 6 cadavers experienced loss of nasal projection. When all maneuvers were taken in total, there was a statically significant average decrease in projection of 8.93% (range, 5.00-13.04%, p = 0.008). CONCLUSION: Primary septoplasty carries a risk of nasal tip projection, with certain maneuvers carrying higher risk.

OBJECTIVE: To determine the difference in nasal bone narrowing between 2 techniques: the low lateral intranasal perforating osteotomy technique and the low lateral continuous osteotomy technique. METHODS: A retrospective analysis of preoperative and postoperative photographs to determine the changes of the dorsal width of the nose (width of plateau of the nose, or dorsal nasal highlight) and the ventral width (junction of the flattened surface of the maxilla and the ascending nasal process of the maxilla). RESULTS: Twenty patients underwent continuous osteotomies, and 40 underwent intranasal perforating osteotomies. The continuous osteotomy technique had a preoperative to postoperative decrease in the ventral width of 7.0% (P < .01). The perforating osteotomy technique had a decrease in the ventral width of 3.6% (P < .001). Neither technique resulted in a statistically significant change in dorsal width (P < .25). There was no significant difference in ventral and dorsal narrowing when comparing continuous osteotomies to perforating. CONCLUSIONS: Both the continuous and perforating osteotomy technique resulted in a decrease in the ventral nasal bone width. No statistical difference was found between continuous and perforating osteotomy techniques in the amount of nasal bone narrowing (P < .25).

OBJECTIVE: To quantify tissue tearing force at various anchoring points on the face. METHODS: This is a prospective anatomic study using 4 fresh cadavers of persons aged 60 to 70 years at the time of death, for a total of 8 sides. Standardized 1-cm distances were measured at the various anchor points, and a single 0 Prolene suture loop was tied at each standardized anchoring point. Steady force was applied perpendicular to the plane of the face with a digital hanging scale. The scale was pulled until the suture ruptured the tissue at the anchoring point. The values at which the tissue ruptured were recorded, averaged, and compared. RESULTS: The average tissue force was 7.01 kg for the root of the zygoma vs 3.44 kg for the temporalis fascia (P < .05). The average tissue force was 5.50 kg for infralobular tissue vs 4.09 kg for tissue of the superficial musculoaponeurotic system located 1 cm anterior to the infralobular tissue (P < .05). The force for the fascia of the sternocleidomastoid was 3.89 kg vs 5.57 kg for the mastoid fascia (P < .05). There was a statistically significant difference between vertical bites of the temporalis fascia at 1.90 kg vs horizontal bites of the temporalis at 5.01 kg (P < .05). CONCLUSION: The tissue tearing force varies by location on the face as well as suture orientation.

OBJECTIVE: To delineate the superior (facial) extent of the platysma muscle. METHODS: A total of 142 facial halves were examined from 71 consecutive deep-plane rhytidectomies performed over a period of 3 months. The platysma muscle was identified and isolated during the procedure. The superior extent of the platysma was measured along the line created by the angle of the mandible to the malar eminence, also known as the malar mandibular line. RESULTS: On average, the platysma extended 3.98 cm along the malar mandibular line, superiorly from the inferior border of the mandible. The platysma was located 3.09 cm inferiorly from the malar eminence along the malar mandibular line. On average, the platysma muscle occupied 56% of the malar mandibular line. CONCLUSION: The platysma muscle may have a more significant facial extension than previously described.

Leprosy is a chronic granulomatous infection of the skin and peripheral nerves that often leads to gross deformation of the nasal skeleton and subsequent formation of a saddle-nose deformity. Reconstruction of the nose following Mycobacterium leprae infection has challenged surgeons for centuries. As a result, a number of different techniques have been attempted with varying outcomes. This article describes the case and surgical treatment of a 37-year old female who presented with a subtotal nasoseptal perforation and saddle-nose deformity secondary to previous infection with leprosy. Reconstruction was achieved via an open septorhinoplasty approach using autologous costal cartilage grafts, yielding a successful postoperative result.

OBJECTIVE: Review the safety profile and subjective efficacy of intradermal botulinum toxin type A in facial pore size and sebum production. DESIGN: Retrospective analysis of 20 patients. RESULTS: Twenty consecutive patients with a single application of intradermal botulinum toxin type A were examined: Patients (17/20) noted an improvement in sebum production and a decrease in pores size at 1 month after injection. No complications were observed, and 17/20 patients were satisfied with the procedure. CONCLUSION: Preliminary data suggests that intradermal botulinum toxin may play a role in decreasing sebum production. Further quantitive study may be necessary to determine effects of intradermal botulinum toxin on pore size.

OBJECTIVE: To determine whether differences of angles between the alar rim and the long axis of the secondary defect in a Zitelli bilobed flap affect alar displacement in a fresh cadaver model. METHODS: In fresh cadaver heads, identical, unilateral 1-cm circular defects were created at the superior alar margin. Three different laterally based bilobed flap templates for reconstruction were used. One template, used on 3 cadavers, had an angle of 60 degrees between the alar rim and the long axis of the secondary defect. Another template, used on 3 cadavers, had an angle of 90 degrees . The last template had an angle of 135 degrees and was used on 2 cadavers. Photographs were taken before the repair and after with the camera and cadaver heads in the same spatial relationship to each other. RESULTS: In the 3 cadavers that had repair using an angle of 60 degrees , all cadavers experienced alar retraction, with a mean displacement of 1.3 mm. This was not a statistically significant change (P = .07). In the defects that had repair using an angle of 90 degrees , there was also no significant alar displacement (P = .72). In the 2 cadavers that underwent repair using an angle of 135 degrees , both ala underwent depression by 1.0 mm. When the differences achieved between the different angles were compared, there was a significant difference in measured distortion between the cadavers that had 90 degrees and 60 degrees vector placement (P = .02). There were no measurable changes to the contralateral maximal nostril distance. CONCLUSIONS: Vector alignment can have an impact on nostril displacement. In bilobed flaps, the axis of the secondary defect may play an important role. This study suggests that secondary defects aligned perpendicular to the nostril have the least amount of alar distortion.

Reconstruction of small and medium-sized defects of the nose poses a challenge to the facial plastic surgeon. Flaps for small to medium-sized defects most often are closed in single-staged procedures as opposed to larger-sized defects. A variety of techniques can be used including secondary intention, primary closure, full-thickness skin grafts, composite grafts, rhomboid flaps, bilobe flaps, dorsal nasal flaps, island flaps, and inferiorly based meliolabial flaps.

OBJECTIVE: To determine the position of the lower eyelid and lateral canthus after release of the lower eyelid retractors with the "inside-out technique" by measuring the marginal reflex distance 2 (MRD2) and using the lateral canthal rounding scale. DESIGN: Retrospective analysis. RESULTS: Of the 171 patients who underwent inside-out blepharoplasty, 78 were followed up for 3 months. Preoperative MRD2 was 0.942 pixels. Postoperatively, the modified MRD2 was 0.903. Although the score of the modified MRD2 was found to decrease postoperatively, the decrease was not statistically significant (P < .07). The lateral rounding scale reviewed an average preoperative score of 2.04 and a postoperative score of 1.99. There was no statistical difference between pre- and postoperative observations based on a 1-tailed t test. No complications were reported. CONCLUSION: Using photographic analysis, the study found no difference in lateral canthal shape or MRD2 before and after surgery in patients who underwent inside-out blepharoplasty.

BACKGROUND: The management of cerebrospinal fluid (CSF) leaks can be challenging. Acellular dermal grafts derived from human cadavers can be used as a replacement material when autogenous materials are unavailable. Fibrin tissue adhesive (FTA) is a wound support product that has been used for hemostatic and tissue fixation purposes. The combined use of acellular dermis in conjunction with FTA for dural repair remains a subject of study. The aim of this study was to evaluate wound healing and tissue compatibility characteristics of acellular dermal substitute material when used both with and without FTA, for repair of a dural tear in a chinchilla model. METHODS: Forty-nine chinchillas were included in this randomized case-control study. The squamous portion of the temporal bone was removed to expose the tegmen. A 2 x 2 mm dural defect was removed to create an iatrogenic CSF leak. Then, animals were randomly assigned to one of three treatment groups: group 1, acellular dermis alone; group 2, acellular dermis with FTA; group 3, fibrinogen, acellular dermis, and FTA. Surgical sites were examined grossly at 1- and 2-week intervals. Temporal bones were examined histologically. RESULTS: Grossly, groups 2 and 3 had significantly less visible CSF leak and brain herniation noted at both 1- and 2-week intervals when compared with group 1. Histological results confirmed the gross results showing the best seal in group 2 and 3. CONCLUSION: Acellular dermis combined with FTA provided superior support compared with acellular dermis alone in repair of induced dural defects.
