Resection of obstructing inferior turbinates following rhinoplasty

Total inferior turbinectomy was carried out in 38 patients who complained of nasal obstruction following rhinoplasty or rhinoseptoplasty and in whom hypertrophied inferior turbinates were found to be the cause of obstruction. Postoperatively, relief of nasal obstruction was reported by 84 percent of patients, while rhinoscopy showed wide, clean nasal airways in 92 percent. Nasal airflow measurements in 32 tested patients showed increased patency in all of them, including 3 who still complained of nasal obstruction postoperatively. The follow-up period ranged from 1 to 7 years (mean 2.8 years). Atrophic changes of the nasal mucosa or chronic purulent infection was not observed in any of the patients. Because the results of partial procedures on the inferior turbinates are often unsatisfactory, I suggest performing total inferior turbinectomy in patients with obstructing inferior turbinates following rhinoplasty.     

Comparison between effects of various partial inferior turbinectomy options on nasal airflow: a computer simulation study

Partial inferior turbinectomy is typically performed on patients suffering from chronic nasal obstruction due to hypertrophy of inferior turbinates and is refractory to other more conservative treatments. The effects of the various options of incision performed on the inferior turbinate in terms of the resulting nasal airflow pattern are examined using computational fluid mechanics. The pressure drops across the severely blocked nose and healthy nose models were found to be 32.3 and 12.3 Pa, respectively, whereas the pressure drops across the nasal cavity following one-third turbinate resection, total turbinate resection and front-end resection were obtained as 5.8, 6.1 and 30.5 Pa correspondingly. Based on the total pressure drop results, the one-third resection option seems to be better than the front-end surgery and the total turbinate resection.     

Rhinoplasty and endoscopic surgery for functional and inflammatory nasal/sinus disorders

The rhinoplastic surgeon when faced with nasal sinusitis has traditionally delayed aesthetic treatment of the nose, referring the patient to the ear, nose, and throat consultant until complete resolution of the inflammatory condition. Often, under such a scenario, the patient found the ear, nose, and throat procedure to be a traumatic experience that discouraged further surgery of an aesthetic nature. The advent of functional endoscopic sinus surgery has significantly modified the management of paranasal sinus disorders. This minimally invasive, sophisticated procedure can easily be combined with rhinoplasty. More recently, an endoscopic approach has been advocated for management of the septum and lower/middle turbinates. The authors call this functional endoscopic nasal surgery. Functional endoscopic nasal surgery allows a clearer view of the operative field (septum and turbinates), a more accurate correction of nasal obstruction, and better control of bleeding. Thus, endoscopic techniques permit the treatment of functional and inflammatory nasal disorders in a single stage, along with aesthetic improvement. Only the patient with severe sinusitis is unsuitable for combined therapy. The authors present their experience based on 72 consecutive cases of combined functional endoscopic sinus surgery/functional endoscopic nasal surgery with aesthetic rhinoplasty. Complications were minimal and functional failures were limited to 4 percent, whereas aesthetic outcomes remained uncompromised.     

Inferior turbinate surgery: an adjunct to successful treatment of nasal obstruction in 408 patients

Septal deviation is often associated with hypertrophy of the contralateral inferior turbinate. Failure to reduce the size of the turbinate at the time of septal reconstruction may result in persistent nasal obstruction. The authors present their experience with 408 patients who underwent one of four turbinate procedures over a 6-year period. Most patients underwent unilateral turbinate surgery, although bilateral procedures were undertaken in 7 percent of patients. A graduated surgical approach was taken that varied according to the amount of turbinate enlargement and the degree to which mucosa and bone were involved. Full-thickness excision of the anterior third to half of the inferior turbinate (turbinectomy) became a favored procedure. Relief of nasal obstruction was obtained in greater than 90 percent of patients. Healing was satisfactory regardless of the method, and complications, including hemorrhage and infection, were few. Long-term follow-up revealed no untoward sequelae, and no patient developed atrophic rhinitis. The authors conclude that turbinate surgery, particularly when unilateral, in the carefully selected patient with nasal obstruction is a useful adjunct to septal surgery.     

Nose surgery: how to prevent a middle vault collapse--a review of 50 patients 3 to 21 years after surgery

There is a conception, likely a misconception, that when performing a nasal osteotomy with a concomitant dorsal hump removal, the upper lateral cartilages are detached or damaged and, over the long-term, respiratory difficulties result because of a middle vault collapse or interference with the internal nasal valve. A follow-up of 50 patients between 3 and 21 years postoperatively provides evidence that this can be prevented. The vast majority (82 percent) reported they were breathing very well for an average of 6.5 years postoperatively. Of the authors' own 38 primary rhinoplasty patients, only two patients (5 percent) reported respiratory difficulties. The authors are unable to substantiate that either the osteotomy or the dorsal hump removal was responsible. Of the 12 patients who had their primary rhinoplasty performed elsewhere, six (50 percent) reported respiratory difficulties before the secondary rhinoplasty at this clinic. Furthermore, an appreciable improvement in breathing was reported by 66.7 percent of these patients after the secondary rhinoplasty. The authors conclude that their gentle proper surgical technique, combined with a good understanding of nasal physiology (with respect to the septum, inferior turbinates, and external and internal valves), allows them to perform a concomitant dorsal hump removal and osteotomy without interfering with nasal physiology.     

The deviated nose: optimizing results using a simplified classification and algorithmic approach

The deviated nose presents a particular challenge to the rhinoplasty surgeon because, frequently, both a functional problem (airway obstruction) and an aesthetic problem must be addressed. An approach to the deviated nose is presented that relies on accurate preoperative planning and precise intraoperative execution of corrective measures to return the nasal dorsum to midline, restore dorsal aesthetic lines, and maintain airway patency. The principles of correction include wide exposure through the open approach, release of all deforming forces to the septum, straightening of the septum while maintaining an adequate dorsal and caudal strut, restoring long-term support, reducing the hypertrophied turbinates, and performing controlled stable percutaneous osteotomies. An operative algorithm is described that emphasizes simplicity and reproducibility, and case studies demonstrate the results that can be achieved with this approach.     

Precision rhinoplasty. Part I: The role of life-size photographs and soft-tissue cephalometric analysis

I describe a simple technique of full-scale life-size photography using marker/stickers and a ruler at the side of the face as an index for magnification. I also report a technique of soft-tissue cephalometric analysis that consists of some new proportion and some old angles and measurements. This technique will enable the plastic surgeon, even if not artistically inclined, to draw an aesthetically pleasing and very proportionate profile outline of the nose and measure the proportions of the front view on the majority of patients. The difference between the patient's nasal outline and the planned nasal definition is then measured and expressed in quarters of millimeters to give the surgeon a very precise numeric guide for surgery. This will help the plastic surgeon define the aesthetic goals very accurately and also might be helpful in detecting other facial disharmonies that might be influential in the outcome of the rhinoplasty. Using this technique of analysis, along with the prediction guidelines extrapolated from my study on soft-tissue response to surgical alteration, one can develop a fairly predictable approach to rhinoplasty.     

The expert teaching system: a new method for learning rhinoplasty using interactive computer graphics

We have developed software that employs interactive computer graphics to simulate the surgical experience of rhinoplasty by allowing the surgeon to experiment within a model of nasal behavior. For any of three preoperative noses, the surgeon can choose and see the effects of dorsal resection, modification of nasal spine or caudal septum, alar cartilage resection, osteotomy, alar wedge resection, and a variety of nasal grafts. The available choices and views total nearly 3000 images, or approximately 200 different surgical solutions. The surgeon can get textual analysis at any time or see accelerated healing to the projected nasal appearance at 1 year. We believe that the ability to experiment without risk, to safely learn the biological laws governing nasal behavior, should augment the development of surgical judgement in rhinoplasty.     

Surgical reduction of hypertrophied inferior turbinates: a comparison of electrofulguration and partial resection

Two adjunctive or primary surgical procedures, partial resection and electrofulguration, are popular today for reducing offending inferior turbinates. Both are relatively successful. However, there seems to be a growing consensus that judicious partial resection of the inferior turbinates is associated with a higher long-term success rate (86 versus 69 percent) as well as a lower postoperative morbidity rate. This paper outlines the specific symptom complex that brought 200 patients to corrective intranasal surgery. These are as follows: nasal obstruction (99 percent), sinus pressure headaches (61 percent), dry, raw pharynx (61 percent), abnormal migration of the nasal mucous blanket or "postnasal drip" (35 percent), and recurrent bacterial rhinosinusitis (57 percent). Based on this symptom complex, this paper attempts to give the expected long-term results when a single operator performed 100 consecutive operations using each technique.     

A composite forearm free flap for the secondary repair of the ruptured Achilles tendon.

The nasal dermal sinus cyst is one of many midline nasal masses that often pose diagnostic and treatment dilemmas for the plastic and reconstructive surgeon. The differential diagnosis of the midline nasal mass includes both congenital and acquired processes. A thorough understanding of its cause is crucial to treatment. A comprehensive discussion of the pathogenesis, diagnosis, sequelae, and surgical management, and a representative case analysis, of the nasal dermal sinus cyst is presented to delineate the role of open rhinoplasty in optimizing the care of this congenital nasal deformity.

Nasal respiratory turbinate function in birds

Nasal respiratory turbinates are complex, epithelially lined structures in nearly all birds and mammals that act as intermittent countercurrent heat exchangers during routine lung ventilation. This study examined avian respiratory turbinate function in five large bird species (115-1,900 g) inhabiting mesic temperate climates. Evaporative water loss and oxygen consumption rates of birds breathing normally (nasopharyngeal breathing) and with nasal turbinates experimentally bypassed (oropharyngeal breathing) were measured. Water and heat loss rates were calculated from lung tidal volumes and nasal and oropharyngeal exhaled air temperatures (T(ex)). Resulting data indicate that respiratory turbinates are equally adaptive across a range of avian orders, regardless of environment, by conserving significant fractions of the daily water and heat budget. Nasal T(ex) of birds was compared to that of lizards, which lack respiratory turbinates. The comparatively high nasal T(ex) of the lizards in similar ambient conditions suggests that their relatively low metabolic rates and correspondingly reduced lung ventilation rates may have constrained selection on similar respiratory adaptations.     

Notch-1 decreased expression contributes to leptin receptor downregulation in nasal epithelium from allergic turbinates

BackgroundAllergic rhinitis is characterized by a remodeling of nasal epithelium. Since the Notch and TGF-β signaling pathways are known to be involved in cell differentiation and remodeling processes and leptin adipokine has already been identified as a marker for homeostasis in human bronchial and nasal epithelial cells of asthmatics, roles played by these pathways have been investigated for chronic allergic rhinitis.MethodsThe leptin/leptin receptor expression has been investigated in a study with 40 biopsies from allergic (AR, n = 18) and non-allergic (C, n = 22) inferior turbinates, using immunohistochemistry, immunofluorescence staining and RT-PCR. In addition, extracts from in vitro samples prepared from primary cells of inferior turbinates as well as in vitro cultured human nasal epithelial RPMI 2650 cells (ATCC-CCL-30) were also tested for leptin expression and activation of the Notch-1 pathway.ResultsWith regards to AR, in vivo expression levels of both leptin and its receptor significantly decreased in comparison to C. Furthermore, leptin receptor mRNA was significantly reduced in AR as compared to C. Immunofluorescence showed an apparent co-expression of leptin receptor with Notch-1, which was not seen with TGF-β. In vitro, in primary turbinate epithelial cells, the expression of leptin receptor and Notch-1 significantly decreased in AR as compared to C. Moreover, in RPMI 2650 cells, leptin receptor expression was shown to be induced by Notch-1 ligand signaling.ConclusionThus, both the leptin and Notch-1 pathways appear to represent markers for epithelial homeostasis in allergic rhinitis.     

External approach for secondary rhinoplasty

A systematic approach, using the external rhinoplasty technique, is presented to aid the plastic surgeon in obtaining improved aesthetic and functional results in patients with postoperative nasal deformities. In over 100 external rhinoplasties, there were no problems with the stairstep transcolumellar incision used to provide complete visualization of the underlying nasal framework. The external approach allows for a more accurate intraoperative anatomic diagnosis and subsequent complete correction of the nasal deformity. Three case reports are presented to demonstrate the indications and versatility of the external approach in secondary rhinoplasty.     

Nasal tip sutures part I: the evolution

Suture techniques for reshaping the nasal tip have been in use for many decades. However, the past two decades have been the most influential in the advancement of the procedures commonly used today. This report details the origin of the major tip suture techniques and tracks their evolution through the years. The early techniques in tip rhinoplasty share a basic principle: the sacrifice of lateral crus integrity to augment the middle and medial crural cartilage to gain tip projection and height. These techniques often disrupt the support mechanisms of the tip lobule, leading to undesirable postoperative results, including supratip fullness, tip asymmetry, tip drop, and an overoperated appearance. Modern nasal tip surgery is founded on the philosophy that suture placement does not simply secure partially excised sections of alar cartilage; rather it aims to directly reshape and reposition the various nasal tip components. The principal suturing methods available in the repertoire of today's rhinoplasty surgeon are the medial crural suture, the middle crura suture, the interdomal suture, the transdomal suture, the lateral crura suture, the medial crura anchor suture, the tip rotation suture, the medial crura footplate suture, and the lateral crura convexity control suture. This report acknowledges past contributions to nasal tip surgery and looks at the recent evolution of techniques commonly used today.     

Efficacy and safety of inferior turbinate coblation-channeling in the treatment of nasal obstructions

The aim of this study was to evaluate the safety and effectiveness of coblation-channeling in the treatment of inferior turbinate hypertrophy. The study was conducted in the Department of ENT Head and Neck Surgery, Split University Hospital Center, Split, Croatia. Fifty-two patients with inferior turbinate hypertrophy who were refractory to medical therapy were evaluated for coblation. The procedures were performed under local anesthesia using an ArthroCare ReFlexUltra 45 wand; three submucosal channels were made per turbinate. Clinical examinations, a questionnaire on individual nasal symptoms (hyposmia, nasal drainage and post-nasal drip), a 10-cm visual analog scale (VAS) grading general nasal obstructions, and rhinomanometry before and 8 weeks after the treatment were administered to assess treatment outcomes. No adverse effects were encountered. Nasal breathing was significantly improved in all patients, decreasing the VAS from a median of 7 (range 2-9) to 1 (range 0-3) (p < 0.001). Total nasal resistance decreased from 0.44 Pa +/- 0.50 to 0.24 Pa +/- 0.11 (p = 0.005). Improvement was statistically significant for all three symptoms (hyposmia [p = 0.005], nasal drainage [p = 0.003] and post-nasal drip [p < 0.001]). In this paper, we demonstrate that coblation-channeling of the hypertrophic inferior turbinate is an effective and safe way to reduce nasal obstruction symptoms.     

Intranasal Volume Changes Caused by the Endoscopic Endonasal Transsphenoidal Approach and Their Effects on Nasal Functions

Objective

We evaluated postoperative changes in nasal cavity volume and their effects on nasal function and symptoms after endoscopic endonasal transsphenoidal approach for antero-central skull base surgery.

Study Design

Retrospective chart review at a tertiary referral center.

Methods

We studied 92 patients who underwent binostril, four-hand, endoscopic endonasal transsphenoidal approach surgery using the bilateral modified nasoseptal rescue flap technique. Pre- and postoperative paranasal computed tomography and the Mimics^® program were used to assess nasal cavity volume changes at three sections. We also performed several pre- and postoperative tests, including the Connecticut Chemosensory Clinical Research Center test, Cross-Cultural Smell Identification Test, Nasal Obstruction Symptoms Evaluation, and Sino-Nasal Outcome Test-20. In addition, a visual analog scale was used to record subjective symptoms. We compared these data with the pre- and postoperative nasal cavity volumes.

Results

Three-dimensional, objective increases in nasal passage volumes were evident between the inferior and middle turbinates (p<0.001) and between the superior turbinate and choana (p = 0.006) postoperatively. However, these did not correlate with subjectively assessed symptoms (NOSE, SNOT-20 and VAS; all nasal cavity areas; p≥0.05) or olfactory dysfunction (CCCRC and CCSIT test; all nasal cavity areas; p≥0.05).

Conclusion

Skull base tumor surgery via an endoscopic endonasal transsphenoidal approach altered the patients’ nasal anatomy, but the changes in nasal cavity volumes did not affect nasal function or symptoms. These results will help surgeons to appropriately expose the surgical field during an endoscopic endonasal transsphenoidal approach.     

Importance of the nasal-to-cervical relationship to the profile in rhinoplasty surgery

There is general agreement that when discussing surgery with the prospective rhinoplasty patient, one may also include discussion of the chin because of the important interrelationship between these two regions. It is apparent that on the profile-lateral view, the four prominences-the forehead, nose, chin, and neck-balance and complement one another. The cervical region, the fourth dimension, was examined to estimate the aesthetic significance of the nasal-to-cervical relationship and to determine the implications to rhinoplasty surgery.Part I of the study was a survey to test the hypothesis that the cervical region affects the perceived impression of the nose. Four standard facial-profile black-and-white photographs were chosen to represent varying degrees of nasal dorsum hump and cervical ptosis problems. Using computer-altering software, only the cervical regions were altered to create a pair of photographs for each of the four profiles: one with a youthful-looking non-ptotic cervical region, the other with a ptotic aged-looking cervical region. Raters were asked to give their first-impression opinions of which nose subjectively appeared "better." Raters consistently (84 percent of the time) chose the nose on the faces with the less ptotic neck as being better. Therefore, a less ptotic neck improved the perceived appearance of the nose.Part II was a retrospective chart review of the rhinoplasty patients of a single surgeon by independent raters. To estimate the aesthetic significance of the nasal-to-cervical relationship, the proportion of patients undergoing rhinoplasty surgery who could have potentially benefited from a youth-restoring neck procedure was determined. Criteria originally described by Ellenbogen and Karlin for judging the results of youth-restoring neck procedures were used as relative indications for neck surgery. An average of 27.2 percent of the patients did not have visible criteria and therefore by definition had relative indications for neck-rejuvenating procedures when undergoing rhinoplasty surgery. As demonstrated in part I of the study, improving the neck could improve the perceived results of the rhinoplasty.Part III of the study validated the Ellenbogen and Karlin criteria. The present authors found that the original criteria were probably based on female patients, that male and older patients had more indications for surgery, and that there was significant interrater agreement with the youthful criteria.In summary, the authors established that a strong nasal-to-cervical relationship exists whereby the perceived appearance of the nose is affected by the neck. The significance of this relationship to rhinoplasty surgery was determined, and it was found that more than 27 percent of rhinoplasty patients could obtain better perceived nasal results with a concomitant neck-rejuvenating procedure. Consequently, discussing neck-rejuvenating procedures with the rhinoplasty patient is valuable.     

The role of septal surgery in management of the deviated nose

The deviated nose represents a complex cosmetic and functional problem. Septal surgery plays a central role in the successful management of the externally deviated nose. This study included 260 patients seeking rhinoplasty to correct external nasal deviations; 75 percent of them had various degrees of nasal obstruction. Septal surgery was necessary in 232 patients (89 percent), not only to improve breathing but also to achieve a straight, symmetrical, external nose as well. A graduated surgical approach was adopted to allow correction of the dorsal and caudal deviations of the nasal septum without weakening its structural support to the dorsum or nasal tip. The approach depended on full mobilization of deviated cartilage, followed by straightening of the cartilage and its fixation in the corrected position by using bony splinting grafts through an external rhinoplasty approach.     

The role of the columellar strut in rhinoplasty: indications and rationale

There are a variety of techniques that can be used to enhance or improve the nasal tip. These techniques often use suture techniques and invisible grafts to achieve the desired result. The former methods have been well described throughout the literature. Among the latter techniques, the columellar strut remains a popular and effective form of an invisible graft in rhinoplasty. The purpose of this article is to define the role of the columellar strut graft, describe how to perform it correctly in rhinoplasty, provide a clinical algorithm for its application, and detail a 15-year retrospective analysis of the senior author's (R.J.R.) experience. Previous references to the importance of the columellar strut graft in rhinoplasty have been described; however, none has formally defined its singular importance in both primary and secondary open rhinoplasty. This article details the role of the columellar strut and its relationship to nasal tip projection and lower lateral cartilage symmetry with an explanation of methods for improving each. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
