Caucasian Mediterranean patients seeking rhinoplasty-Anthropometric measurements and prevalence of major deformities.

OBJECTIVE: To describe the average values of the nasal anthropometric measurements of Caucasian Mediterranean patients seeking rhinoplasty and evaluate the major nasal deformities. DESIGN: Prospective, observational and cross-sectional study. SETTING: Centro Hospitalar do Porto. PARTICIPANTS: A 100 Caucasian Mediterranean patients seeking rhinoplasty. OUTCOMES: Standardized photography was used to obtain nasal anthropometric measurements and to evaluate the major nasal defects. Data regarding age, gender, skin type and Fitzpatrick scale were also collected. RESULTS: There was a statistically significant difference in the means values of palpebral fissure, intercanthal width, upper lip height, nasal root width, morphological nose width, nose height, nasal tip projection and nasofrontal-hump and nasofrontal-supratip angles between females and males. The major nasal deformity was dorsal hump (78.0%), followed by rinomegalia (53.0%) and boxy bulbous tip (47.0%). CONCLUSION: The present study shows statistically significant gender differences between anthropometric nasal measurements and the mean values are greater than standard values obtained on general population. This might be one of the reasons why Caucasian Mediterranean patients seek aesthetical rhinoplasty. On both genders, dorsal hump, rinomegalia and boxy bulbous tip were the major nasal defects. This emphasize the importance of rhinoplasty techniques designed to reconstruct nasal dorsum and nasal tip on Caucasian Mediterranean patients. To the best of our knowledge, our study is the first study of digital anthropometric nasal analysis and evaluation of major nasal defects specifically in Caucasian Mediterranean patients who applied for rhinoplasty. With this results, we provide a reference material for the evaluation of the Caucasian and Mediterranean patient when planning a cosmetic nasal surgery.

Full-Thickness Entire Nasal Alar Reconstruction Using a Forehead Flap in Asians: No Cartilaginous Infrastructural Lining Is Necessary.

Full-thickness defects of the entire nasal ala, including the rim, can be challenging to reconstruct. A forehead flap may provide a more imperceptible and natural-appearing reconstructed nasal ala. Previously, many authors have insisted adding cartilaginous infrastructural support for an entire, full-thickness defect to keep the postoperative alar structure symmetrical. They finally use a forehead flap after thinning of the distal covering portion subcutaneously, possibly for a Caucasian-type nasal ala. However, Asian skin has a thicker and more compact dermis than that of Caucasian skin, and the Asian ala is rounder and thicker. There may be another approach for an Asian-type nasal ala. The authors propose the possibility of nasal alar reconstruction for an entire, full-thickness defect in Asians using a forehead flap without structural support. Six patients with entire full-thickness nasal alar defects treated with full-thickness forehead flaps above the periosteum without structural support were reviewed. Five patients demonstrated esthetically good to excellent outcomes in color, texture, and symmetry. Their nasal linings were reconstructed using mucoperiosteal flaps or mucosal grafts. One patient treated with a nasal lining using a local flap showed a fair result esthetically. Asians forehead above the periosteum has adequate thickness and supportability to reconstruct the entire full-thickness nasal ala in Asians. No cartilage support is necessary.

A Systematized Strategy in Corrective Rhinoplasty for the Asian Deviated Nose.

BACKGROUND: A deviated nose is a common deformity encountered in rhinoplasty. Over the past several decades, a variety of rhinoplasty techniques have been described focusing on the classification of bony and cartilaginous deviation. Nevertheless, corrective rhinoplasty is still a challenging procedure even for experienced surgeons because of the high recurrence rate of deviation. In attempt to reduce the recurrence rate, the author systematized the complex procedures by using a single technique regardless of the classification of a deviation. MATERIALS AND METHODS: Forty patients who underwent corrective rhinoplasty between June 2009 and December 2014 were reviewed retrospectively. All the patients were operated using 4 main surgical procedures: anterior approach septal correction, unilateral osteotomy, and medialization of the deviated complex to the contralateral intact side, and dorsal augmentation with a dermofat graft. Assessment of improvement was based on photo standardization. The degree of nasal deviation, nasofrontal angle, tip projection-to-nasal length ratio, vertical line of the upper lip-to-tip projection ratio, and columellar-labial angle were measured. RESULTS: Preoperative and postoperative anthropometric measurements revealed that the mean degree of deviation changed from 10.19° to 3.43° (P < 0.01), and the degree of nasofrontal angle changed from 131.55° to 133.14° (P < 0.01). All patients responded to both the preoperative and postoperative questionnaires. The questionnaires revealed a significant functional and cosmetic improvement from 36.84° to 76.95° and 39.45° to 79.41°, respectively (P < 0.0001). CONCLUSIONS: This systematized strategy to correct the Asian deviated nose provided reproducible and consistent results It also resulted in low recurrence rates and high postoperative satisfaction among patients.

Preventing Elevated Radix Deformity in Asian Rhinoplasty with a Chimeric Dorsal-Glabellar Construct.

BACKGROUND: Asian facial aesthetic surgery should enhance, but not change, natural features. Augmentation rhinoplasty is a hallmark of Asian cosmetic surgery. In the authors' experience, I-shaped implants can elevate and efface the radix, leading to an unnatural appearance (elevated radix deformity). OBJECTIVES: The Chimeric technique was developed to control final radix position and preserve the nasal profile. We aim to demonstrate that the Chimeric technique promotes forward projection, not elevation, of the radix. METHODS: Between 2013 and 2015, 49 patients underwent rhinoplasty with I-shaped implants. Nineteen patients had Chimeric dorsal-glabellar implants, 30 did not. Standardized photographs were obtained at every visit. Novel and established photogrammetric parameters were used to describe radix position and position change. A retrospective chart review provided additional procedural details and outcomes data. RESULTS: Patients were followed for 10.8 months (range, 2-36 months). Nasal height increase (113% vs 107%) and bridge length increase (118% vs 105%) were significantly greater when the Chimeric technique was not performed (P < .0001). The nasofrontal angle increased 6° in both groups; there was no difference between groups. The vector of radix position change was 26.1° in the Chimeric group and 63.4° in the traditional group (P < .0001). CONCLUSIONS: The Chimeric technique preserves the nasal profile with a favorable (horizontal) radix transposition vector. There was not a significant difference in final radix position when Chimeric rhinoplasty was performed because that is controlled by implant thickness and position. The technique did not blunt the radix significantly. LEVEL OF EVIDENCE 4: Therapeutic.

Nasal tip surgery for cleft nose in Asians.

"Collapsed nasal tip," one of the most characteristic features of cleft lip nose, resembles the effect of pushing the nose tip with a finger and is especially noticeable among Asians. The authors examined a rhinoplasty technique for improving collapsed nasal tip. Using an intercartilaginous incision, the distal nasal framework, including the alar cartilages, and the caudal septum were widely exposed. A septal extension graft was fixed to the caudal septum, and the alar cartilages were precisely sutured to the extension graft using markings transferred to the extension graft. This procedure was applied to 15 Asian rhinoplasties, with all patients having substantial improvement in the shape of their nasal tip. Comparing those with and without a history of rhinoplasty, effecting a projection of the nasal tip was more difficult in patients with a history of previous rhinoplasties. The advantages of this technique include inconspicuous scarring and versatility in the modification of the nasal tip. Rhinoplasty during the growth period should be planned with consideration of future augmentation rhinoplasties.

Lengthening the short nose in Asians: key maneuvers and surgical results.

IMPORTANCE: Using objective anthropometric measurement, this study reports the outcome of surgical correction of short-nose deformities in Asian patients. OBJECTIVE: To present our experience in lengthening the short nose in Asians and report the surgical results. DESIGN, SETTING, AND PATIENTS: In this retrospective review, we study the cases of 36 patients who underwent surgical correction of short-nose deformity. The effect of nasal lengthening was analyzed using anthropometric measurement, including nasion to tip-defining point (N-TDP), nasal tip projection (NTP), nasofrontal angle (NFA), and columellar-facial angle (CFA). EXPOSURES: Surgical correction of short-nose deformity. MAIN OUTCOME MEASURES: The preoperative and postoperative N-TDP, NTP, NFA, and CFA and patient satisfaction. RESULTS: The mean postoperative follow-up duration was 29.8 months. The cause of the short nose was congenital in 18 cases and secondary to previous rhinoplasty in 18 cases. Septal tissue, conchal cartilage, costal cartilage, and conchal composite tissue were used as graft materials. The key procedures for lengthening included septal extension graft reinforced with extended spreader, dorsal onlay, and tip grafts. The N-TDP increased by 11.2%, and CFA decreased from 122.6° to 111.1°. The NFA changed from 148.9° to 148.5°. The NTP ratio, measured using the Goode method, decreased from 0.53 to 0.50. The increase of N-TDP was greater in patients undergoing the costal cartilage grafting procedure than in those who received septal or conchal cartilage. All patients were satisfied with the aesthetic results, and there were no serious complications. CONCLUSIONS AND RELEVANCE: In Asians, the key maneuvers for lengthening were septal extension graft reinforced with extended spreader and dorsal onlay graft. Rib cartilage provided superior lengthening effect compared with other cartilage. LEVEL OF EVIDENCE: 4.

Secondary Asian rhinoplasty: lengthening the short nose.

BACKGROUND: Short nose deformity results from primary short nose, previous rhinoplasty, or trauma. A septal extension graft using rib cartilage can be placed to address this deformity. Indications for this procedure include previously damaged septal cartilage, innate septal issues, saddle nose deformity, skin problems, and secondary deformities of the cleft lip and nose. OBJECTIVES: The authors describe their experience using rib cartilage grafts for septal extension to correct short nose deformity in Asian patients. METHODS: From January 2005 through February 2010, the authors used a rib cartilage graft for septal extension in 38 consecutive Asian rhinoplasty patients with primary (n = 5) or secondary (n = 33) short nose deformity. In cases where the septum had been overresected in a previous rhinoplasty, a reinforcement procedure was performed using additional supportive rib cartilage grafts. RESULTS: The mean duration of follow-up was 2.5 years. Of the 38 treated patients, 7 were male and 31 were female (mean age, 28.5 years). A single septal extension graft with rib cartilage was used in 32 cases, whereas a double graft was used in 6 cases. The average external lengthening of the nose from nasal root to tip was 8 mm. All patients were satisfied with the shape of the lengthened nose. There was 1 case of pneumothorax, but complications were otherwise rare. Neither cartilage exposure nor infection was observed. CONCLUSIONS: The authors have obtained good aesthetic results using a rib cartilage graft for septal extension in the treatment of short nose. This technique may be particularly useful in cases where the septal cartilage is unavailable for harvest because of previous rhinoplasty or trauma.

Superficial mastoid fascia as an accessible donor for various augmentations in Asian rhinoplasty.

This study was designed to assess the anatomic characteristics and clinical versatility of superficial mastoid fascia as a soft-tissue donor for augmentation in Asian rhinoplasty. Dissections were performed on four fresh cadavers (eight ears) for histologic study. A 3×10 mm2-sized full layer of skin and underlying soft tissue was harvested from the postauricular area, transversely and longitudinally (cephalic and caudal directions), 5 mm apart from the midpoint of the auriculocephalic sulcus. The average fascial thickness and nerve distribution were assessed using digital microscopic images after haematoxylin and eosin (H&E) staining. In the histologic study, the average measured thickness of the superficial mastoid fascia was between 3.8 and 4.5 mm in various directions. Clinically, 33 subjects who underwent rhinoplasty using superficial mastoid fascia were assessed prospectively. When soft tissue was needed in various types of augmentations, a longitudinal incision was made on the posterior auriculocephalic sulcus and the maximum thickness of superficial mastoid fascia was harvested. The sizes of the superficial mastoid fascia used in the 33 subjects ranged from 0.4×2.5 cm2 to 1.2×4.2 cm2. The superficial mastoid fascia was grafted regionally for the nasion, tip and nasal dorsum. In two cases, hypertrophic scars developed at the donor site. Four subjects experienced transient dysaesthesia and hypoaesthesia at the donor area postoperatively. Superficial mastoid fascia may be a useful resource in rhinoplasty as a donor for various types of augmentations, allowing easy access without prominent scarring or permanent sensory nerve damage when a low-to-moderate volume of soft tissue is required.

Ethnic considerations of the crooked nose.

Ethnic features must be taken into account when planning surgery of a patient with a crooked nose. A systematic approach is presented with emphasis on reinforcing structural support, correcting functional and cosmetic abnormalities, aligning structures, and using camouflage techniques to improve appearance and function.

Reconstruction of nasal cutaneous defects in Asians.

OBJECTIVES: Proper selection of reconstruction method is the key point to get a successful result in nasal reconstruction. The purposes of this study are to report the author's experience and to present a surgical algorithm in reconstruction of the nasal defects in Asian. METHODS: Retrospective medical record analysis was performed for 40 patients who underwent nasal reconstruction between March 1996 and February 2006 at a tertiary referral hospital. Male to female ratio was 24:16, average age was 56 years, and average follow-up period was 25 months. Etiology, location, size, reconstruction method and surgical results were analyzed. RESULTS: Majority of the defects (36/40) resulted from resection of a neoplasm. Among tumors, basal cell carcinoma accounted for 75% (27/36) followed by squamous cell carcinoma 8% (3/36). The defect was located in the dorsum in 11 cases, lateral wall in 9, ala in 8, tip in 4, and involved more than two sites in 8. In 2/3 of the cases, the defect size was less than 2cm. Local flap was used in 29 cases, primary closure in 6 cases, and skin graft in 5 cases. Among local flaps, nasolabial flap was useful for defects of the ala and multiple subunits while large nasal tip defects needed forehead flap. Transposition flaps were used for the small to medium sized defects of the nasal sidewall or dorsum. Reinforcement cartilage graft was used in 9 cases. Second stage refinement procedure was performed in 2 patients. Partial necrosis resulted in 2 cases but none ended up in total loss. CONCLUSIONS: A local flap is the most versatile method for reconstruction of cutaneous defects of the Asian nose. The site and size of the defect are key considerations in choosing the local flap. Asian skin characteristics influence the design, execution, and the outcomes of the local flap.

Nasal tip augmentation in Asians using autogenous cartilage.

OBJECTIVES: To present surgical techniques and results of nasal tip augmentation in Asian noses and suggest a surgical algorithm for a successful outcome. STUDY DESIGN: A case series at a tertiary hospital. SUBJECTS AND METHODS: One hundred and seven patients who had undergone nasal tip augmentation using autogenous cartilages from January 2005 to December 2006 were enrolled in the study. Medical records, graphic operation records, and standardized patient photographs were retrospectively reviewed. Initial diagnoses, techniques for tip augmentation, combined tip surgery techniques, surgical results, and complications were analyzed. RESULTS: Initial diagnoses included deviated nose, hump nose, saddle nose, low-profile nose, and short nose. An external approach was used in 74 percent and intranasal approach in 26 percent. For augmentation of the tip projection, onlay grafts with or without columellar strut (59%) and septal extension grafts with or without onlay grafts (25%) were the most commonly used techniques. Ninety-three percent of the patients were satisfied with the results. Complications included tip deviation and visible tip graft. CONCLUSION: Augmentation of nasal tip projection in Asians can be effectively performed using autogenous cartilage. Onlay graft and septal extension graft are two important techniques for a successful outcome.

Correction of the Asian deviated nose with no hump using unilateral bony mobilisation and dorsal septal suture fixation.

A deviated nose is corrected by straight realignment and long-term maintenance of the bony and cartilaginous structure. Traditional rhinoplasty usually involves complete separation of both upper lateral cartilages from the septum and bilateral bony mobilisation after osteotomy. In the Asian deviated nose with no hump, these procedures are intrinsically destabilising and may weaken the supporting bony and cartilaginous structure. To avoid these problems, I performed unilateral bony mobilisation with anterior wedge resection and suture fixation of the dorsal septum to the nasal bone without separation of the upper lateral cartilage. This manoeuvre is simple and reproducible and produces satisfactory straightening and maintenance of the nasal dorsum while maximally preserving the structural support. Here, I describe the surgical techniques including the choice of the site of unilateral osteotomy and wedge resection, a new classification of bony deviation, two surgical modifications applied to different types of deviation and rationale of dorsal septal suture fixation. Also, clinical cases of nasal deviation are presented.

Key maneuvers for successful correction of a deviated nose in Asians.

BACKGROUND: The authors present surgical results of 64 Asian patients with deviated nose and introduce important key maneuvers used in the surgery. METHODS: Sixty-four consecutive patients who underwent corrective rhinoplasty because of a deviated nose were analyzed retrospectively. Approaches and techniques used for the surgery, surgical results, and complications were evaluated. A questionnaire was used to evaluate each patient's functional and esthetic satisfaction. Preoperative and postoperative standardized photographs of the face were evaluated to judge objectively the esthetic outcomes of the surgery. RESULTS: An endonasal approach was used in 44 patients and an open approach was used in 20 patients. Five important key maneuvers to correct the deviation were noted, in the order of frequency: septoplasty, osteotomy, spreader graft, turbinoplasty, and camouflage graft. Additional procedures included augmentation of the dorsum, tip surgery, and hump removal. On a 5-point box scale of 0-4, the patients scored their satisfaction on functional improvements as 3.2+/-0.79 and their esthetic satisfaction as 3.0+/-0.8. The objective evaluation of the appearance showed complete correction in 84.4%, a minimally visible deviation in 10.9%, and a residual deviation but less than before surgery in 4.7%. Aside from residual deviations, complications included a slight depression of the middorsum after spreader graft and a malpositioning of the dorsal cartilage graft. CONCLUSION: Deviated nose in Asians can be managed successfully by combining key maneuvers that correct specific anatomic abnormalities. Many of these key maneuvers require modifications that take into account the race-specific characteristics of the Asian nose.

Columella lengthening in nasal tip plasty of Orientals.

To elevate the nasal tip in Orientals, two simple adjunctive procedures are presented. Either V-Y advancement or earlobe composite graft can be used after the open rhinoplasty incision on the columella-labial junction. Over the past 6 years, 62 Oriental patients with short columella were treated with one of the above procedures. The nasal tip projection as well as nasal tip appearance greatly improved. The scar in the columellar base posed no problems, and none of the patients complained about the scar. The procedures are particularly useful for cosmetic rhinoplasty in Orientals as well as in cleft lip nasal deformity.
