Airflow Considerations and the Effect of Webster's Triangle in Reduction Rhinoplasty.

BACKGROUND: Reduction rhinoplasties, regardless of the methods used (structural or preservation), can cause a reduction in the internal nasal volume, which may lead to breathing problems. In 1977, Webster proposed preserving a little triangle in the beginning of the lower lateral osteotomy line to prevent breathing problem. However, its importance is still controversial. OBJECTIVES: and methods: This prospective randomized controlled study (level of evidence 1) included 46 patients without nasal breathing problem. High-to-low (Webster's triangle preservation) osteotomy (control group, n = 23) and low-to-low osteotomy (study group, n = 23) were performed. All operations were performed according to the proposed volumetric rhinoplasty steps (examination/measurement, prevention and treatment). Nasal obstruction symptom evaluation (NOSE) test, visual analog scale, acoustic rhinometry, rhinomanometry, peak nasal inspiratory flow (PNIF), and three-dimensional measurements were performed in all patients. Breathing tests were repeated before and 6 months after surgery with and without xylometazoline administration. RESULTS: No statistically significant difference in NOSE and visual analog scale scores was found between the two groups. Acoustic rhinometry, PNIF, and rhinomanometry findings showed no statistically significant breathing difference between the two groups. CONCLUSIONS: In reduction rhinoplasties, a decrease in the internal volume may be expected as directly proportional with the reduction amount. The decrease in the internal volume may create nasal breathing problems. To prevent it, nasal airflow should be adjusted according to new anatomy. In this study, we discussed "volumetric rhinoplasty" steps to prevent breathing problems in reduction rhinoplasty. Following these steps, not preserving Webster's triangle (low-to-low osteotomy) has no effect on the nasal airway.

A New Technique for Robust Stabilization in the Keystone Area during Extracorporeal Septorhinoplasty.

Although extracorporeal septorhinoplasty is the most powerful technique for correcting deviated and leaning noses, many investigators have abandoned it because of keystone problems. The authors defined a new neoseptum fixation technique and used it in 10 patients in 2016. Preoperative and postoperative Nasal Obstruction Symptom Evaluation scale and peak nasal inspiratory flow measurement, and septal indexes of the patients were compared. There was statistically significant improvement in the respiratory condition of all patients. No recurrence or dorsal irregularity has been observed. This new, easily applicable, and robust fixation method of extracorporeal septorhinoplasty may be a definitive solution to prevent keystone irregularities. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, IV.

Revisiting the role of columellar strut graft in primary open approach rhinoplasty.

BACKGROUND: The effect of a columellar strut graft on final nasal tip position has been a subject of ongoing debate. The purpose of this study was to retrospectively analyze a series of 100 consecutive primary rhinoplasty cases performed without the use of columellar strut grafts, with a specific focus directed toward comparing preoperative, morphed, and actual postoperative changes in nasal tip position. METHODS: Data were collected from patient charts and digital images of 100 consecutive primary open rhinoplasty patients. Preoperative, morphed, and actual postoperative digital images were quantitatively analyzed using image-processing software to compare various anatomical features, including nasal tip projection, nasolabial angle, and Goode ratio. Patient satisfaction regarding long-term postoperative results was also surveyed. RESULTS: Primary rhinoplasty did not demonstrate a universal trend toward either an increase or a decrease in nasal tip projection. The planned changes in nasal tip projection, nasal tip rotation, and nasal profile proportions were obtained with statistically significant accuracy without the use of columellar strut grafts. The overall incidence of columellar contour irregularities was 3 percent. CONCLUSION: In primary open approach rhinoplasty, if native anatomical support structures of the nasal tip are preserved or reconstructed, preoperative goals regarding nasal tip projection, nasal profile proportions, and columellar integrity can be consistently achieved without using columellar strut grafts.

A new flap design: prefabricated neuro-osseous flap.

We hypothesized that an osseous tissue can be prefabricated with a peripheral nerve by vascular induction, and by using a rat model, we tested this hypothesis.Twenty Wistar rats were used in the prefabricated neuro-osseous flap study. Bilateral sciatic nerves were placed linearly within the medullary cavities of the femurs. Left femurs were accepted as the experimental group. The right femurs of all the rats were used as internal control where the sciatic nerves were ligated at the bony entrance of the flap.After 6 weeks, all experimental femur flaps were viable. Radioactivity counts and metabolic activity studies showed viable and functional bone tissue in experimental group compared with control group (P = 0.001). On microangiographic evaluation, significant dilatation of the perineural vasculature was observed in experimental group. Histologic investigations showed viable bone tissue only in the experimental group flaps.Due to its easy applicability, reproducibility, and robust circulation, the prefabricated neuro-osseous flap would be an option in reconstructive surgery.

A new microvascular anastomosis technique using muscle graft.

A novel microvascular anastomosis technique is described. Forty-five male Sprague-Dawley rats were divided equally into three groups before undergoing femoral artery anastomosis. The first group received standard eight-suture anastomotic repair. Group 2 (muscle group) received three sutures plus autogenous muscle graft wrapped around the anastomosis. In group 3 (fascial surface group), a muscle graft was wrapped around the anastomosis with the fascial side of the graft facing the anastomosis. Significantly less time and suture usage were noted using both fascial surface and muscle groups compared with controls (p < 0.05). No significant difference regarding patency rates or aneurysm formation existed among the three groups (p > 0.05). Additionally, grade 2 anastomotic leakage was less frequent in the study groups compared with the control group (p < 0.05). This new microvascular anastomosis technique took less time and achieved better performance than standard anastomotic repair.

The effects of hyperhomocysteinemia on the microcirculation of skin flaps.

BACKGROUND: Hyperhomocysteinemia is an independent risk factor for atherothrombotic disease and venous thrombosis. The effects of hyperhomocysteinemia on the microcirculation were studied in vascular diseases. The authors aimed to investigate the effects of hyperhomocysteinemia on the microcirculation of random-pattern skin flaps. METHODS: Twenty-two male Sprague-Dawley rats, divided into two groups, were used in this study. The rats in group 1 (control) were fed the TD.07112 diet, and the rats in group 2 (experimental group) were fed the TD.07114 diet, enriched in methionine for 30 days, to induce severe hyperhomocysteinemia. The plasma homocysteine, folic acid, vitamin B12, and vitamin B6 levels were evaluated on days 0 and 30. Distally based skin flaps were elevated on day 30 and evaluated by direct observation, microangiography, and light microscopy on day 37. RESULTS: Mean homocysteine blood levels were 211.76 ± 56.55 µM/liter in group 2 and 14.48 ± 2.00 µM/liter in group 1 on day 30. The rate of necrosis was significantly higher in group 2 (59.00 ± 4.38 percent) compared with group 1 (32.54 ± 6.13 percent; p < 0.01). Microangiographic findings were similar to direct observation results. Microvessel calibration was reduced in group 2. In group 1, structures of epidermis and dermis were normal; however, there was a slight mononuclear cell infiltration along with thick collagen fibers. A more prominent mononuclear cell infiltration with fields of loose epidermis, associated with inflammation and infiltration, were observed in group 2. CONCLUSION: The authors demonstrated, for the first time, that hyperhomocysteinemia severely suppressed the microvasculature of skin flaps, as shown by increased flap necrosis and reduced microvessel calibration in the experimental group.

An unusual variation of deltoid muscle.

An unusual anatomic variation of the deltoid muscle was found in a 45-year-old female cadaver during dissection of the right upper extremity. The posterior fibers of the right deltoid muscle were enclosed in a distinct fascial sheet and the deltoid muscle was seen to arise from the middle 1/3 of the medial border of the scapula. There was no accompanying vascular or neural anomaly of the deltoid muscle. To the best of our knowledge, unilateral posterior separation of the deltoid muscle with a distinct fascia has not been described previously. While dissecting deltoid, posterior deltoid, or scapular flaps, the surgeon needs to look out for this variation because it may cause confusion.

Postoperative satisfaction and the patient's body image, life satisfaction, and self-esteem: a retrospective study comparing adolescent girls and boys after cosmetic surgery.

BACKGROUND: Cosmetic surgery procedures are more complex for adolescents than for adults because there are more factors affecting patient satisfaction, especially psychological factors. This study was designed to find answers to four main questions: (1) whether postoperative satisfaction rates differ statistically between males and females, (2) whether postoperative satisfaction correlates significantly with the self-esteem, body image, life satisfaction trilogy, (3) what the postoperative patient satisfaction and cosmetic procedure rates are among adolescents by years, and (4) whether a statistically significant relationship exists between postoperative satisfaction and a willingness of adolescents to undergo another cosmetic surgery. METHODS: The study enrolled 86 of 165 patients who underwent surgery between January 2001 and June 2005. A simple poll consisting of 12 simple questions was used to collect data. RESULTS: No statistically significant difference was found in postoperative satisfaction rates between males and females. The findings show that postoperative satisfaction is significantly related to self-esteem, body image, and life satisfaction. The patient satisfaction rate was 93.83%, and there was no increase in adolescent cosmetic surgery rates over the years. CONCLUSION: Adolescents are good candidates for cosmetic surgery, but patients must be evaluated carefully. Any suspicion about a patient's psychological status must result in a psychiatric consultation.
