Endoscopic partial inferior turbinoplasty

Inferior Turbinate Hypertrophy: A Comparison of Surgical Techniques

Introduction Nasal obstruction is one of the most frequently reported symptoms in clinical practice. The second most common cause of nasal obstruction is inferior turbinate hypertrophy, a nasal pathology for which surgical treatment is often required. This study aims to determine the most effective surgical method in patients with inferior turbinate hypertrophy (ITH). Materials and methods The study was performed from September 2018 to October 2019 in the Otolaryngology-Head and Neck Surgery Department of the Evangelismos Hospital of Athens. The study population comprised 205 patients that underwent surgery and were monitored in the hospital. Radiofrequency ablation (RFA) was the method used in 73 patients, 68 patients were treated with the microdebrider-assisted turbinoplasty (MAT), and the remaining 64 patients were operated on using electrocautery (EC). Following surgery, postoperative complications were assessed and quantified. Results Overall, 205 patients underwent surgery. The first group (n=73) was operated on using radiofrequency ablation and had a complication rate of 30.1%. Out of 73 patients, 51 recovered without complications. The remaining 22 had complications, consisting of 16 patients with bleeding and six with postnasal drip. The second group (n=68) was treated using the microdebrider method. The complication rate was 26.5%, where 50 patients did not present with any symptoms post-operatively and 18 exhibited symptoms. Specifically, postnasal drip was more prevalent with this method as all 18 patients showed postnasal drip as their complication. The third group (n=64) was treated with electrocautery. Patients in this group had the most complications (n=24), 16 were attributed to postnasal drip and eight to infections, treated promptly with oral antibiotics. The complication rate using this method was 37.5%. Conclusion In our study, the microdebrider-assisted turbinoplasty offered the lowest complication rate, followed by radiofrequency ablation and electrocautery. However, all three methods managed to alleviate the nasal obstruction and treat inferior turbinate hypertrophy. More research is needed as a lack of consensus remains regarding the optimal surgical technique for lower turbinate hypertrophy.

To Study the Long Term Outcome of Endoscopic Septoplasty with Microdebrider Assisted Inferior Turbinoplasty (MAIT) Versus Medial Flap Turbinoplasty (MFT)

To study the long term outcome of endoscopic septoplasty with microdebrider assisted inferior turbinoplasty (MAIT) versus medial flap turbinoplasty (MFT). The present study was conducted in the Department of ENT, Government Medical College, Amritsar. Patients with symptomatic persistent nasal obstruction were recruited from ENT outdoor clinics. The nasal obstruction was persistent despite medical therapy that included a minimum 4 weeks. The study was primarily a double blinded prospective randomized control study including 120 patients, where all patients enrolled at odd numbers were taken for endoscopic septoplasty with microdebrider assisted inferior turbinoplasty and all patients with even numbers were taken for endoscopic septoplasty with MFT. Patient-scored nasal obstruction (1-5) along with blindly assessed nasal airway patency ratings (1-4) was done at 3 and 24 months postoperatively. A total of 120 patients were recruited in the study. The mean ages of the MAIT and MFT groups were 28.61 ± 14.8 and 30.25 ± 8.36 years, respectively. Average follow-up period was 21.9 ± 6.3 months. Nasal obstruction was improved in both techniques at 3 months, but after long term follow up, it was highly significant for MFT along with improvement in preoperative symptoms p < 0.001. No patients complained of worsening of their obstruction. Nasal patency at 24 months, a significant proportion of patients had a greater nasal assessment by a blind assessor with 97.1% in MFT and 81.9% MAIT with mild to no obstruction. In MAIT group 16.6% had pain/discomfort, 23.6% had discharge which were the major complications, but crusting (MAIT 10% and MFT 3.3%), adhesions (MAIT 13.8% and MFT 1.6%). The medial flap inferior turbinoplasty (MFT) is technically straight forward procedure that provides long term more effective and satisfactory the patient in relieving nasal obstruction, without significant risk of complications. The long term follow up of MAIT is required as there was increase in need of decongestion and they might require second procedure as MFT.

Maxillary sinusitis developed as sequelae of accidental middle turbinectomy that occurred during nasotracheal intubation: a case report

BACKGROUND

Nasotracheal intubation is a very useful technique for orofacial or dental surgery. However, the technique itself can be more traumatic than that of orotracheal intubation. Complications such as turbinectomy or bleeding are often reported. However, little is known about the follow-up of patients after these complications.

CASE PRESENTATION

The present case describes an accidental middle turbinectomy that led to endotracheal tube obstruction during nasotracheal intubation, and discusses its long-term follow-up. A 19-year-old man underwent mandibular surgery under general anesthesia and nasotracheal intubation. His right middle turbinate was completely avulsed and became firmly occluded within the tube during nasotracheal intubation. The nasotracheal intubation was performed again and the operation was completed safely. The patient was discharged without sequelae after postoperative care. However, he had symptoms of nasal obstruction and sleep disturbance for 3 months postoperatively. Synechiae were detected between the nasal septum and lateral nasal wall on a right rhinoscopic examination and facial computed tomography at 3 months postoperatively. Additionally, he showed ipsilateral maxillary sinusitis on facial computed tomography at the 2-year follow-up examination.

CONCLUSIONS

Nasotracheal intubation can cause late complications as well as early complications. Therefore, if nasotracheal intubation is to be performed, the anesthesiologist should identify the nasal anatomy of the patient accurately and prepare appropriately. In addition, if complications occur, follow-up observation should be performed.

Coblation versus microdebrider-assisted turbinoplasty for endoscopic inferior turbinates reduction

OBJECTIVE

Patients suffering from persistent inferior turbinates hypertrophy refractory to medical treatments require surgical intervention where the main aim is symptomatic relief without any complications. Extraturbinoplasty is one of the preferred procedures for turbinate reduction due to its efficacy in freeing up nasal space by removing the obstructing soft tissue and bone while preserving the turbinate mucosa. We sought to evaluate the effectiveness and safety of microdebrider assisted turbinoplasty (MAT) and coblation assisted turbinoplasty (CAT) performed as an extraturbinoplasty procedure.

METHODS

A prospective randomized comparative trial was conducted among patients with bilateral nasal blockage secondary to inferior turbinates hypertrophy. Patients were randomly assigned to MAT or CAT. An extraturbinal medial flap turbinoplasty was performed for both techniques. Symptom assessment was based on the visual analogue score for nasal obstruction, sneezing, rhinorrhea, headache and hyposmia. Turbinate size, edema and secretions were assessed by nasoendoscopic examination. The assessments were done preoperatively, at 1st postoperative week, 2nd and 3rd postoperative months. Postoperative morbidity like pain, bleeding, crusting and synechiae were documented. The clinical outcomes of both techniques were analyzed using repeated measures ANOVA.

RESULTS

A total of 33 participants were recruited, 17 patients randomized for MAT and 16 patients for CAT. Nasal obstruction, discharge, sneezing, headache and hyposmia significantly reduced from 1st week until 3 months for both procedures. Similar significant reductions were seen for turbinate size, edema and secretions. However, there was no significant difference in symptoms and turbinate size reduction were seen between both groups at the first postoperative week, 2nd and 3rd postoperative months. There was significant longer operating time for CAT when compared to MAT (p = 0.001). The postoperative complications of bleeding, crusting and synechiae did not occur in both groups.

CONCLUSION

Both MAT and CAT were equally effective in improving nasal symptoms and achieving turbinate size reduction in patients with inferior turbinate hypertrophy. Both MAT and CAT offer maximal relieve in patients experiencing inferior turbinates hypertrophy by removing the hypertrophied soft tissue together with the turbinate bone without any complications.

A Prospective Study to Compare the Efficacy of Powered Turbinectomy Versus Submucous Resection in the Surgical Management of Inferior Turbinate Hypertrophy

Over the years many surgical techniques have been described in the literature for the treatment of inferior turbinate hypertrophy (ITH) but the debate for ideal procedure is still on. In our study we are comparing two surgical procedures namely submucosal resection (SMR) of inferior turbinate and Powered inferior turbinectomy (PT) for the management of ITH. Surgical procedures are to be analyzed in terms of results and complications by subjective and Objective assessment. A prospective study was conducted from 1st December 2011 to 1st June 2013. Subjective assessment of nasal obstruction was done by visual analogue scoring before surgery and graded into none, mild, moderate, and severe. Patients were also subjected to nasal endoscopy for objective assessment of inferior turbinate size and graded as I, II, III. A total of 60 patients were operated (30 patients in each group), patients in Group A underwent SMR and in Group B patients PT was performed. Patients were assessed for various parameters like age, gender, laterality, intra operative and postoperative complications. Overall improvement of 66.7% in Nasal Obstruction and 76.7% in size of inferior turbinate was seen in Group A, whereas improvement of 90% in nasal Obstruction and 83.3% in size of turbinate was seen in Group B. Both SMR and PT are efficient methods for relieving nasal obstruction related to ITH. However, the results in our study confirm that PT is a safe and effective procedure in relieving nasal obstruction and enabling optimal volume reduction with preservation of function of the inferior turbinate.

Turbinate reduction with complete preservation of mucosa and submucosa during rhinoplasty

BACKGROUND

Turbinate surgery is an important adjunct to functional and cosmetic rhinoplasty. Many studies have analyzed the effects of various mucosal-sparing techniques, such as radiofrequency, laser, shaver, and others. These techniques, however, result in the destruction of the submucosal tissue of the turbinate. The goal of this study was to determine whether excellent functional outcome could be achieved with techniques sparing both the mucosa and submucosa from destruction when addressing the turbinates in rhinoplasty surgery.

MATERIALS AND METHODS

A prospective single-surgeon clinical study analyzing submucous resection of turbinate bone without destruction of the submucosa or mucosa in patients undergoing functional-esthetic rhinoplasty was performed. In all, 122 patients (47 men, 75 women, average age: 32.1 years, range: 16-69 years) were eligible for the study. The functional outcome was measured prospectively using the Nasal Obstruction Symptom Evaluation (NOSE) score. Occurrence of complications was documented.

RESULTS

Of over 1000 surgical patients, 307 candidates fulfilled multiple selection criteria and were entered in a rhinoplasty database. The surveys sufficient for the present study were completed by 122 of 307 patients (39.7%), of whom 91 patients reported improvement, 14 patients reported no subjective change, and 12 patients reported minimal worsening of nasal breathing. Overall, postoperative function was excellent (preoperative vs. postoperative NOSE score 47.5 vs. 20.1, p < 0.001). A large proportion of patients reporting worsening of symptoms (50%) were diagnosed with decongestant nasal spray abuse. Specific complications such as bleeding, foul drainage, dryness, and crusting were not reported.

CONCLUSION

All function-bearing structures of the inferior nasal turbinates, mucosa, and submucosa can be fully preserved without impairment of functional outcome during rhinoplasty. The technique of selective submucous bone resection is as an excellent alternative for patients undergoing rhinoplasty for concomitant treatment or prevention of nasal obstruction.

[Nasal turbinate surgery]

The nose forms the first 8 cm of the upper respiratory tract and is responsible for cleansing, humidification, and temperature control of the supplied air. This is also referred to as conditioning. The nasal valve region, formed by the head of the lower nasal concha, portions of the cartilaginous septum, and the upper lateral cartilage, is responsible for diffusing and accelerating the respiratory airflow. Prerequisite are regular mucociliary clearance and sufficient air passage. Hypertrophy of the lower nasal turbinate is one of the most common causes of symptomatic nasal congestion. In unclear cases, rhinometric procedures are available. In addition to conservative therapy of allergic or vasomotor rhinitis by specific immunotherapy or topical corticoids, numerous interventional procedures are available to reduce conchal tissue. All modern methods have a high degree of protection of the respiratory mucosa in common.

Comparative study between partial inferior turbinotomy and microdebrider-assisted inferior turbinoplasty

PURPOSE

The purpose of our study was to compare the inferior turbinotomy and the microdebrider-assisted inferior turbinoplasty in patients with hypertrophy of the inferior turbinate.

MATERIAL AND METHODS

We carried out a retrospective review of 205 patients, 96 women and 109 men, with a mean age of 48 years, operated on for hypertrophy of the inferior turbinate between May 2005 and May 2012. Forty-seven patients were excluded from our study because in these patients, nasal obstruction was caused by a specific pathologic condition (allergy, tumors or polyps, recurrent rhinosinusitis, etc). The remaining 158 patients were randomly assigned to undergo partial inferior turbinoplasty through the use of microdebrider (group A, n = 79) or partial inferior turbinotomy (group B, n = 79). Surgical outcome was evaluated according to 4 distinct parameters: nasal endoscopic findings, nasal subjective symptoms, anterior rhinomanometry, and nasal mucociliary transport time. These evaluations were made before surgery and 1 week and 3 months after surgery. The follow-up was a minimum of 24 months and a maximum of 60 months, with a mean follow-up of 42 months.

RESULTS

Turbinate edema and secretions decreased significantly (P < 0.05) in groups A and B 3 months after surgery. In group A, crusting was not observed after surgery. In group B, crusting had increased significantly (P < 0.005) 1 week after surgery and then decreased significantly at the third month after surgery. Subjective nasal symptoms including nasal obstruction, sneezing, snoring, itchy nose, hyposmia, headache, and dryness were significantly improved in both groups from the third month after surgery (P < 0.05). Rhinomanometric measurements demonstrated a significant nasal flow increase at 3 months (P < 0.05). The mean nasal mucociliary transport time slightly increased in both groups 1 week after surgery, and then restabilized to preoperative values at the third-month follow-up in both groups (difference not significant).

CONCLUSIONS

Microdebrider-assisted inferior turbinoplasty and partial inferior turbinotomy are very effective surgical techniques for solving hypertrophy of the inferior turbinates and therefore related problems of nasal obstruction. Microdebrider-assisted inferior turbinoplasty compared to partial inferior turbinotomy ensures a greater preservation of the nasal mucosa to prevent nasal bleeding.

Evaluation of the Nasal Surgical Questionnaire for Monitoring Results of Septoplasty

Monitoring the results of surgery is important. The otorhinolaryngology department of our hospital currently uses preoperative and postoperative versions of the Nasal Surgical Questionnaire (NSQ) for continuous evaluation of nasal septoplasty. In this study, 55 patients undergoing septoplasty answered the preoperative version twice to assess the NSQ's test-retest precision, and 75 patients answered the preoperative questionnaire before and the postoperative one 6 months after surgery to evaluate the NSQ's ability to detect change in symptoms following surgery. Both the pre- and postoperative versions of the NSQ use separate visual analogue scales (VAS) to assess nasal obstruction during the day, at night, and during exercise. Other nasal symptoms are graded as secondary outcomes using 4-point Likert scales. The mean VAS scores for the two preoperative obstruction ratings were not significantly different. The scores were significantly higher than in a normal population. There were also significant differences between preoperative and postoperative ratings. The mean pre- and postoperative scores at night for those who reported complete improvement were 66.1 and 8.4, substantial improvement 74.5 and 24.2, and no improvement 83.3 and 76.4. The NSQ reliably assesses nasal symptoms in patients and may be useful for both short and long term prospective studies of septoplasty.

Perioperative Management of Antithrombotic Therapy in Common Otolaryngologic Surgical Procedures: State of the Art Review

OBJECTIVE

The perioperative management of patients undergoing otolaryngologic procedures is increasingly complicated by the use of newer antithrombotic agents. Furthermore, with advances in anesthesia and surgical technique, otolaryngologists are presented with the challenge of operating on patients with advanced comorbid diseases. The objective of this review is to provide evidence-based recommendations on perioperative antithrombotic management for common otolaryngologic procedures.

DATA SOURCES

PubMed/MEDLINE.

REVIEW METHODS

Selected literature on patient-specific thromboembolic risk, rate of bleeding complications in otolaryngologic procedures, and the interruption of antithrombotic therapy is reviewed and interpreted by expert opinion.

CONCLUSIONS

By stratifying patients into either low thromboembolic risk (≤ 5%) or high thromboembolic risk (> 5%) and interpreting this in the context of procedural bleed risk and potential clinical consequences in the event of a bleed, otolaryngologists can make evidence-based decisions to determine the appropriate perioperative management of antithrombotic therapy.

IMPLICATIONS FOR PRACTICE

When the perioperative management of antithrombotic therapy is being decided, 3 critical factors must be considered systematically: the patient's inherent thromboembolic risk, the risk and potential consequences of bleeding related to the procedure, and the timing of interruption of thromboembolic therapy.

A systematic review of patient-reported nasal obstruction scores: defining normative and symptomatic ranges in surgical patients

IMPORTANCE A gold standard objective measure of nasal airway obstruction (NAO) does not currently exist, so patient-reported measures are commonly used, particularly the Nasal Obstruction Symptom Evaluation (NOSE) scale and the visual analog scale (VAS). However, questions remain regarding how best to use these instruments. OBJECTIVES To systematically review studies on NOSE and VAS scores in patients with NAO and to compile and standardize the data to (1) define symptomatic and normative values for presurgical and postsurgical patients with NAO, asymptomatic individuals, and the general population; (2) determine if postsurgical scores are comparable with asymptomatic scores; and (3) determine if there is a clinically useful preoperative and postoperative score change. EVIDENCE REVIEW A systematic review of the literature was performed through PubMed for studies assessing NOSE and VAS scores in patients with chronic NAO. Strict inclusion criteria were applied to focus on anatomic obstruction only. For statistical analysis, the patients were classified as asymptomatic, presurgical and postsurgical with NAO, and the general population. FINDINGS The mean (SD) NOSE and VAS scores for a patient with NAO were 65 (22) and 6.9 (2.3), respectively. The mean postsurgical NOSE and VAS scores were 23 (20) and 2.1 (2.2), respectively. The mean asymptomatic individual NOSE and VAS scores were 15 (17) and 2.1 (1.6). The mean NOSE and VAS scores for the general population were 42 (27) and 4.6 (2.6), respectively. The mean presurgical to postsurgical change was more than 40 for NOSE scores and more than 4.0 for VAS scores. CONCLUSIONS AND RELEVANCE We have shown that normative and abnormal value ranges for NOSE and VAS can be established for clinical use. Given the consistency of both scales, we conclude that these measures can be used as a clinically meaningful measure of successful surgical outcomes.

Endoscopic microdebrider-assisted inferior turbinoplasty with and without posterior nasal neurectomy

OBJECTIVE

Endoscopic microdebrider-assisted inferior turbinoplasty (EMAIT) has been recognized as an efficient surgical technique in the management of hypertrophied inferior turbinate. In an attempt to further increase surgical successful outcomes, posterior nasal neurectomy (PNN) was developed. The aim of this retrospective case-control study was to assess the position of PNN in the surgery of hypertrophied turbinate.

METHODS

Seventy patients were assigned to the two treatment groups: Group A (EMAIT) and Group B (EMAIT and PNN). Subjective outcomes were represented by symptom score and quality of life scores (Rhinoconjunctivitis Quality of Life Questionnaire - RQLQ). Objective outcomes were nasal resistance, saccharin transit time and acoustic rhinometry parameters.

RESULTS

The survey demonstrated that symptoms and objective parameters improved postoperatively in both groups, with no statistical significant differences in objective and subjective outcomes between the surgical groups.

CONCLUSION

The addition of PNN appears to offer no additional benefit in the subjective and objective outcome related with surgery of hypertrophied inferior turbinate. However, longer follow-up studies and larger number of patients are required in order to validate our results.

[Microdebrider-assisted inferior turbinoplasty. Minimally invasive technique for the treatment of nasal airway obstruction caused by enlarged turbinates]

BACKGROUND

Various methods are available for the surgical treatment of nasal airway obstruction caused by enlarged turbinates. These methods include partial turbinectomy, submucosal electrocautery, radiofrequency surgery, and laser turbinoplasty, all of which can have adverse effects such as defects of the mucous lining of the turbinates, prolonged postoperative healing, and bleeding. The purpose of this study was to analyse the effectiveness and potential adverse effects of microdebrider-assisted inferior turbinoplasty (MAIT), which is a less commonly used treatment option.

MATERIALS AND METHODS

In a prospective randomized study, 35 patients underwent microdebrider-assisted inferior turbinoplasty. Two control groups (35 patients each) underwent conventional partial turbinectomy or submucosal electrocautery. Endoscopic and functional studies (active anterior rhinomanometry, saccharin test) were performed before surgery and 2, 4, and 24 weeks after surgery. Pain and other postoperative problems were assessed using analogue scales.

RESULTS

After 2 weeks, MAIT patients, unlike the other patients, showed almost no more mucosal lesions. After 4 weeks, mean saccharin clearance time was 11.1 min in the MAIT group, 15.9 min in the partial turbinectomy group, and 13.7 min in the electrocautery group. When the patients were asked to rate their symptoms on a scale of 0-10, the mean score in the fourth postoperative week was 6.1 in the MAIT group, 7.7 in the partial turbinectomy group, and 7.8 in the electrocautery group. Rhinomanometry showed a mean flow rate increase from 178 ml/s to 574 ml/s after MAIT (401 ml/s after partial turbinectomy, 361 ml/s after electrocautery).

CONCLUSION

Microdebrider-assisted inferior turbinoplasty is a minimally invasive method for reducing inferior turbinate size and maintaining mucosal integrity. It has the advantages of a short healing time, only a mild decrease in mucociliary clearance, only minor postoperative problems, and a good functional outcome.

Transoral submucosal resection of the inferior turbinate: a novel approach to functional rhinoplasty

BACKGROUND

In the presence of turbinate dysfunction, an inferior turbinectomy for persistent hypertrophy of bone and/or mucosa may be performed. We sought to explore anatomic feasibility of a transoral turbinectomy.

METHODS

After transoral inferior turbinectomy in 12 cadavers, average distances from the external nasal valve to inferior turbinate and from pyriform aperture to inferior turbinate were compared. Average "area of access" was calculated. Preoperative and postoperative nasal length, tip projection, and alar-base width were also compared.

RESULTS

Average distance from external nasal valve to inferior turbinate was 32.4 mm. Average distance from aperture to inferior turbinate was 2.4 mm (P < 0.0001). Average "areas of access" to nasal vault through the external nasal valve and mouth were 183.9 mm(2) and 243.6 mm(2) (P = 0.07), respectively.

CONCLUSIONS

The transoral approach provides a larger "area of access" to the turbinate, a statistically significant reduction of distance to target, no postoperative changes in nasal soft tissue, and easier instrumentation.

Ventricular tachycardia during microdebrider-assisted turbinectomy: An electrocardiographic artifact

Interference of monitored electrocardiogram is common during different surgical procedures using electrical equipment. The electrical devices used induce artifacts in the electrocardiographic tracing, which may resemble serious arrhythmia. We describe a case of electrocardiographic artifact resembling ventricular tachycardia with the use of a Storz unidrive microdebrider during inferior turbinectomy under general anesthesia. This case report highlights the importance of knowledge of various equipment-related electrocardiographic artifacts in avoiding unnecessary and harmful therapeutic interventions.

Surgery of the turbinates and "empty nose" syndrome

Surgical therapy of the inferior and/or middle turbinate is indicated when conservative treatment options have failed. The desired goal is a reduction of the soft tissue volume of the turbinates regarding the individual anatomic findings, whilst simultaneously conserving as much mucosa as possible. As the turbinates serve as a functional entity within the nose, they ensure climatisation, humidification and cleaning of the inhaled air. Thus free nasal breathing means a decent quality of life, as well.Regarding the multitude of different surgical techniques, we confirm that no ideal standard technique for turbinate reduction has been developed so far. Moreover, there is a lack of prospective and comparable long-term studies, which makes it difficult to recommend evidence-based surgical techniques. However, the anterior turbinoplasty seems to fulfil the preconditions of limited tissue reduction and mucosa-preservation, and therefore it is the method of choice today.Radical resection of the turbinates may lead to severe functional disturbances developing a secondary atrophic rhinitis. The "empty nose" syndrome is a specific entity within the secondary atrophic rhinitis where intranasal changes in airflow result in disturbed climatisation and also interfere with pulmonary function. Results deriving from an actual in vivo study of climatisation and airflow in "empty nose" patients are presented.

Use of microdebriders in common rhinologic disorders

Powered instruments have been introduced into otorhinolaryngology practice over the last decade. These instruments were accepted immediately by many institutions, and continuing development has led to the current use of microdebriders in a variety of surgical procedures in otorhinolaryngology. In clinical rhinology, they were first used in endoscopic sinus surgery to facilitate working on deep planes, but have subsequently been adopted in various conditions. This article presents an evaluation of the use of microdebriders in common rhinological disorders.

Patients with positive allergen test have less favorable outcome after endoscopic microdebrider-assisted inferior turbinoplasty

BACKGROUND

Endoscopic microdebrider-assisted inferior turbinoplasty is a newly developed surgical technique to treat patients with nasal obstruction. Although the procedure has been reported to be safe and effective, we tested the hypothesis that the prognosis might deteriorate with time in allergic rhinitis patients as identified by a positive allergen test in patients who have a persistent regional inflammation of the nose. We assessed the degree of nasal obstruction in a prospective cohort to investigate whether positive allergen test predicts outcome.

METHODS

In 70 consecutive patients, the symptom of nasal obstruction was evaluated subjectively by a visual analog scale (VAS) and objectively by acoustic rhinometry using cross-sectional area of the second notch (CSA-2) and nasal cavity volume before operation, and 3 months, 12 months after operation, respectively. Then, patients were classified and compared according to the multiple-antigen simultaneous test (MAST).

RESULTS

Both MAST(+) and MAST(-) groups showed statistically significant improvement in VAS score, CSA-2, and nasal cavity volume at 12 months after operation (p < 0.01). Of note, MAST(+) patients showed less favorable results than MAST(-) patients at 12 months after operation (p < 0.05).

CONCLUSION

Microdebrider-assisted inferior turbinoplasty provides effective relief for patients with nasal obstruction. However, such turbinate surgery may be successful only for a short period of time in patients with allergic rhinitis. Our finding suggests that, in selecting appropriate candidates, surgeons should consider criteria other than symptomatology, especially in patients with allergic rhinitis who may have manifestations other than at the level of the inferior turbinate contributing to nasal blockage.

Evaluation of nasal symptoms and mucociliary function in patients with allergic rhinitis treated with chemosurgery using trichloroacetic acid

PURPOSE

We treated allergic rhinitis with trichloroacetic acid (TCA) applied to the inferior turbinates. Further clinical evaluations were made to determine the effect of TCA application on symptoms of allergic rhinitis. We also report the results of measurement of the mucociliary transit time (saccharin time) and nasal airway resistance.

MATERIALS AND METHODS

A group of 54 patients with perennial allergic rhinitis was treated with 80% TCA applied to the inferior turbinate. Further clinical evaluations were made to determine the effect of TCA application on symptom scores of allergic rhinitis. We also report the results of measurement of the mucociliary transit time (saccharin time) and nasal airway resistance in those cases.

RESULTS

The most common complaint, nasal obstruction, improved effectively in 82% of cases, watery rhinorrhea in 86%, and sneezing in 86%, 1 year after treatment. A significant decrease in scoring was noted for subjective nasal obstruction, watery rhinorrhea, and sneezing. Nasal airway resistance was effectively reduced 1 year after treatment, and the difference was statically significant. In our study, saccharin time appeared to be shortened in the early and late periods after the TCA application. There was a statistical difference between the before- and after-treatment groups.

CONCLUSIONS

We concluded that TCA treatment was quite effective for controlling nasal allergic symptoms and that it does not damage the mucociliary function.

Long-term comparison between submucosal cauterization and powered reduction of the inferior turbinates

OBJECTIVES/HYPOTHESIS

To evaluate the results of powered turbinoplasty and to compare these with submucosal cauterization of the inferior turbinates.

STUDY DESIGN

Prospective, randomized, comparative surgical trial.

METHODS

Nineteen patients with medication-resistant chronic nasal obstruction caused by inferior turbinate hypertrophy were randomized to undergo powered turbinoplasty on one side and submucosal cauterization on the other. For each side, an extensive assessment (symptom scoring, endoscopic scoring, and acoustic rhinometry) was recorded preoperatively and on week 1, week 3, month 3, year 1, and year 5 postoperatively.

RESULTS

Powered turbinoplasty was superior to submucosal cauterization on all aspects of the assessment. A significant difference (P < .05) was noted for postoperative crusting, endoscopical scoring of turbinate size, and acoustic rhinometry measurements of nasal cavity volume and mean area at the level of the nasal valve. In addition, the results of powered turbinoplasty were still apparent on long term follow-up, whereas submucosal cauterization was associated with a recurrence of turbinate hypertrophy.

CONCLUSION

Performing a powered turbinoplasty leads to decreased patient morbidity during the postoperative healing and to a better control of long-term results when compared with submucosal cauterization.

Comparative study on the long-term effectiveness between coblation- and microdebrider-assisted partial turbinoplasty

OBJECTIVES

Various surgical methods have been tried to relieve the symptoms of nasal obstruction in patients with inferior turbinate hypertrophy. Recently, coblation that uses the radiofrequency and microdebrider is being increasingly used in turbinate surgery. The aim of this study was to compare the long-term postoperative outcome between the coblation- and microdebrider-assisted partial turbinoplasty.

METHODS

We selected 60 patients for this prospective study who had nasal obstruction and hypertrophied turbinate mucosa that was refractory to medical treatment. Thirty patients were treated with coblation (group 1) and 30 patients were treated with microdebrider (group 2). Postoperative changes in degree of nasal obstruction were evaluated prospectively at 3, 6, and 12 months after the procedure. A cross-sectional area of second notch and volume of nasal cavity were compared at 12 months after operation. Operation time, duration of crust formation, postnasal drip, and postoperative bleeding were also compared.

RESULTS

Nasal obstruction was improved significantly in both groups at 3, 6, and 12 months after the procedure. However, when compared between two groups, symptom improvement was statistically significant in group 2 at 12 months after surgery. Acoustic rhinometry performed at 12 months demonstrated a significant increase of cross-sectional area of second notch and volume of nasal cavity in group 2 in comparison with group 1. There were no significant differences in degree of postnasal drip, operation time, or duration of crust formation between the two groups.

CONCLUSION

This study suggests that microdebrider-assisted partial turbinoplasty is more effective and satisfactory in long-term relief of nasal obstruction and reduction in mucosal volume of anterior head of inferior turbinate.

Powered endoscopic septoplasty for septal deviation and isolated spurs

Septoplasty is commonly performed for nasal airway obstruction or rhinologic headache due to contact irritation, often in conjunction with other nasal procedures, including cosmetic rhinoplasty and endoscopic sinus surgery.Traditionally, it is performed before these procedures via a "headlight" technique. This article describes the use of the microdebrider in 29 cases of endoscopic septoplasty. Many of the procedures were performed in conjunction with functional endoscopic sinus surgery; however, several were performed as an isolated procedure or with inferior turbinoplasty. The technique is described in detail. All 29 patients had significant improvement in their symptoms, and no patient developed a perforation or postoperative hematoma. Conversion to a traditional septoplasty was required in 1 case because of the severity of the deviation. Power-assisted endoscopic septoplasty is a useful adjunct in cases involving isolated septal spurs or moderate septal deviations. Patients with severe nasal obstruction due to caudal deflection of the septum off the nasal spine are better served with traditional headlight septoplasty.

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 reduction in children using Holmium YAG laser-a clinical and histological study

BACKGROUND AND OBJECTIVES

To compare the efficacy and safety of inferior turbinate reduction in children using Holmium:YAG (Ho:Yag) laser and diathermy. Histological effects of these treatments on turbinate tissue are also studied.

STUDY DESIGN/MATERIALS AND METHODS

A retrospective review and structured telephone interview of paediatric cases treated with Ho:Yag laser and diathermy to inferior turbinates. The complications, morbidity and efficacy were quantified. Histological sections of inferior turbinates treated with diathermy (surface and submucosal) and laser were compared.

RESULTS

Efficacy in the laser (n = 8) and diathermy group (n = 11) was similar. The complication/morbidity score was lower in the laser group, 1.92 versus 3.48, (P = 0.04, CI: 0.01, 2). Long-term benefit was 50 and 36% in the laser and diathermy group respectively. Histology showed very limited tissue damage in all methods of treatment.

CONCLUSIONS

Ho:Yag laser treatment is equally efficacious, but causes less complications and morbidity compared to surface diathermy. Both treatment methods have poor long-term efficacy, which may be related to limited tissue damage.

Surgical treatment of the inferior turbinate: new techniques

PURPOSE OF REVIEW

Nasal obstruction causing airway resistance is often a result of structural abnormalities. Frequently, turbinate reduction procedures have been used after failure of medical management to address enlarged inferior turbinates, which potentially cause functional narrowing at the nasal valve. Controversy still exists as to the best or most appropriate method for surgical reduction of the inferior turbinate. The multitude of approaches available to the rhinologist is a testament to the lack of a single established method.

RECENT FINDINGS

This paper highlights recently published literature regarding current popular and cutting-edge techniques. There is a trend toward less invasive techniques that can potentially be performed in the clinic setting, rather than in the operating room. In addition, surgical turbinate intervention demonstrates benefit in controlling symptoms of allergic rhinitis other than nasal obstruction.

SUMMARY

Surgical reduction of the inferior turbinate can be performed using a variety of techniques. When analyzing different methods, emphasis on efficacy, function preservation, and avoidance of complications is paramount.

Pediatric endoscopic transnasal adenoid ablation

We describe a technique in which suction diathermy is used for adenoid ablation through a solely endoscopic transnasal approach in the older pediatric population. This procedure has proved to be both effective and convenient during other transnasal endoscopic procedures, as it provides excellent visualization of both the superior and inferior parts of the nasopharynx and results in minimal to no bleeding in the adenoid bed. In all cases to date, there has been complete resolution of preoperative problems of infection, pain, and bleeding. All patients had good control of postoperative pain. There has been no evidence of postoperative nasopharyngeal stenosis and no velopharyngeal insufficiency. Although transnasal adenoid ablation is not appropriate for the entire pediatric population, this procedure has multiple benefits when another endoscopic sinonasal procedure is planned, when there is neck instability, or when enhanced visualization of the nasopharynx is desired.

Comparison of laser induced effects on hyperplastic inferior nasal turbinates by means of scanning electron microscopy

BACKGROUND AND OBJECTIVE

Various laser systems have been used for volume reduction of hyperplastic inferior nasal turbinates. Many studies have thus reported about clinical experiences concerning short and long term results. Although there are also some clinical investigations on histological changes after laser treatment, there is a lack of examinations by means of scanning electron microscopy (SEM) in order to especially investigate laser induced superficial tissue effects (ablation, carbonization, and coagulation).

MATERIALS AND METHODS

Directly following operative excision, three hyperplastic nasal turbinates were treated by laser light of five common medical laser systems and their corresponding wavelengths, using identical laser parameters (irradiance, laser spot diameter) and a reproducible application procedure. After passing through an ethanol dehydration process, the thermal effects on the tissue (carbonization, coagulation, and ablation) were investigated and photographed via SEM.

RESULTS

Depending on the laser wavelength used, tissue responses which could be observed by SEM greatly differ with respect to ablation, coagulation, and carbonization zones. While the CO(2) laser showed a precise cutting of tissue via ablation with only slight thermal effects on the adjoining tissue, Argon-ion-, Nd:YAG-, and diode-lasers provided for an intense destruction of both the surrounding, superficial respiratory epithelium, and the tissue in the depth of the turbinates, resulting from the development of rather large carbonization and coagulation zones. Ho:YAG-laser light induced precise vaporization in addition to remarkable superficial coagulation of the tissue, which was of smaller extent than after treatment with Nd:YAG- and diode-laser, but comparable to the Argon-ion-laser.

CONCLUSIONS

In the course of this study SEM proved to be especially suitable for the examination of tissue changes on the surface of laser treated turbinates (i.g., destruction of respiratory epithelium). According to our results, Argon-ion-, Nd:YAG-, and diode-lasers seem to be useful for an effective and bloodless reduction of hyperplastic turbinates. However, broad coagulation zones may lead to consecutive complications and side effects. Due to its good ablation and superficial coagulation capabilities, Ho:YAG-laser light also seems to be usable for an effective turbinate reduction, but its low thermal effects in the depth of the tissue may lead to bleedings during treatment. Laser light of the CO(2) laser showed the lowest thermal tissue effects of the lasers investigated and therefore holds the risk of bleedings during treatment and the need of more than one therapeutic session to get a sufficient result. This investigation revealed that physicians, who are performing endonasal laser treatment, must be aware of the varying tissue effects of different medical laser systems to get a more aimed effect and to avoid intra- and post-operative complications (e.g., Rhinitis sicca, bone sequestration of the turbinate, bleedings, ...).
