Postoperative Upper Airway Volume Measurements Among Children With Craniofacial Abnormalities.

OBJECTIVE: To measure postoperative airway volumes among patients with craniofacial abnormalities and compare them to normative values. STUDY DESIGN: Retrospective, comparative study. SETTING: Academic Medical Center. METHODS: Retrospective analysis of imaging of children with craniofacial abnormalities treated at NYU Langone Health from January 2013 to February 2021. Upper airway volumes postcraniofacial surgery were measured using 3D processing software (Dolphin 3D, version 11.95). These values were compared with published normative values. RESULTS: Twenty-one subjects were identified and compared to normative values. The postoperative oropharyngeal volumes were on average 43.7% smaller than the normative values (P < .001), and the total upper airway volumes were 31.6% smaller (P = .003). No significant differences were observed in the nasopharyngeal or hypopharyngeal volumes of the study cohort compared to the normative data. Among children ages 12 to 17 years (n = 13), the mean oropharyngeal volumes were 47.6% smaller than normal (P < .001), and the mean total upper airway volumes were 34.6% smaller than normal (P < .001). Among children ages 7 to 11 years (n = 8), the mean oropharyngeal volumes were 35.1% smaller than normal (P = .049), but no difference in mean total upper airway volume was observed. CONCLUSION: In children with craniofacial anomalies, postoperative airway volumes remain lower than normative values. However, even a slight increase in airway volume can yield a substantial increase in flow rate. 3D airway evaluations are a valuable tool for surgical planning and analysis and can help with optimizing airway dynamics.

Myofibroma of the pinna: a case report and review of the literature.

BACKGROUND: Myofibromas are rare mesenchymal tumors with a predilection for the head, neck, and oral cavity. Primarily affecting infants and young children, these tumors typically manifest as superficial painless nodules. Diagnosis is confirmed through histopathological examination of a biopsy, revealing nodules characterized by spindle cell proliferation. To our knowledge, only two cases of pinna myofibroma have been previously reported in the literature. CASE PRESENTATION: Here, we present the case of a three-year-old male who developed a myofibroma of the left auricle following trauma to the area one year earlier. The patient underwent surgical resection without any postoperative complications. The patient later returned with a lesion consistent with hypertrophic scar. CONCLUSIONS: This study aims to provide a comprehensive review of the clinical presentation, histopathologic and immunohistochemical features, and surgical management of this unique case of myofibroma of the pinna.

International Pediatric Otolaryngology Group: Consensus guidelines on the diagnosis and management of non-tuberculous mycobacterial cervicofacial lymphadenitis.

INTRODUCTION: Non-tuberculous mycobacterial (NTM) infection commonly manifests as subacute or chronic cervicofacial lymphadenitis in immunocompetent children. The optimal management of this pathology remains controversial. OBJECTIVES: This international consensus guideline aims to understand the practice patterns for NTM cervicofacial lymphadenitis and to address the primary diagnostic and management challenges. METHODS: A modified three-iterative Delphi method was used to establish expert recommendations on the diagnostic considerations, expectant or medical management, and operative considerations. The recommendations herein are derived from current expert consensus and critical review of the literature. SETTING: Multinational, multi-institutional, tertiary pediatric hospitals. RESULTS: Consensus recommendations include diagnostic work-up, goals of treatment and management options including surgery, prolonged antibiotic therapy and observation. CONCLUSION: The recommendations formulated in this International Pediatric Otolaryngology Group (IPOG) consensus statement on the diagnosis and management of patients with NTM lymphadenitis are aimed at improving patient care and promoting future hypothesis generation.

International Pediatric Otolaryngology Group (IPOG) consensus recommendations: Evaluation and management of congenital tracheal stenosis.

OBJECTIVES: To outline an expert-based consensus of recommendations for the diagnosis and management of pediatric patients with congenital tracheal stenosis. METHODS: Expert opinions were sought from members of the International Pediatric Otolaryngology Group (IPOG) via completion of an 18-item survey utilizing an iterative Delphi method and review of the literature. RESULTS: Forty-three members completed the survey providing recommendations regarding the initial history, clinical evaluation, diagnostic evaluation, temporizing measures, definitive repair, and post-repair care of children with congenital tracheal stenosis. CONCLUSION: These recommendations are intended to be used to support clinical decision-making regarding the evaluation and management of children with congenital tracheal stenosis. Responses highlight the diverse management strategies and the importance of a multidisciplinary approach to care of these patients.

The Surgical Treatment of Robin Sequence: Neonatal Mandibular Distraction Osteogenesis in the Unfavorable Patient.

INTRODUCTION: Neonates with severe Pierre Robin sequence (PRS) can be treated by mandibular distraction osteogenesis (MDO), tongue-lip adhesion, or tracheostomy; however, there is an active debate regarding the indications of MDO in this patient population. Published algorithms identify tracheomalacia, bronchomalacia, laryngomalacia, hypotonic syndromes, and central sleep apnea as contraindications for MDO and indications for tracheostomy, but these comorbidities may exist along a spectrum of severity. The authors propose that appropriately selected neonates with PRS who concurrently express 1 or more of these traditional contraindications may be successfully treated with MDO. METHODS: The authors performed a 5-year retrospective chart review of all neonates who underwent MDO for treatment of severe PRS. All patients expressed a comorbidity previously identified as an indication for tracheostomy. Pre- and postoperative characteristics were recorded. Apnea/hypopnea index (AHI) before and after MDO were compared using 2-tailed repeated measures t-test. RESULTS: The authors identified 12 patients with severe PRS and conditions associated with contraindications to MDO: 9 (75.0%) patients had laryngomalacia, 6 (50.0%) patients had tracheomalacia, 2 (16.6%) patients had bronchomalacia, 1 (8.3%) patient had central sleep apnea, and 3 (25.0%) patients had hypotonia. Five (41.7%) patients underwent concurrent gastrostomy tube placement due to feeding insufficiency. Average birthweight was 3.0 kg. Average pre-op AHI was 34.8. Average post-op AHI was 7.3. All patients successfully underwent MDO with avoidance of tracheostomy. CONCLUSIONS: By employing an interdisciplinary evaluation of patient candidacy, MDO can safely and effectively treat upper airway obstruction and avoid tracheostomy in higher-risk neonatal patients with traditional indications for tracheostomy.

Sleep-Disordered Breathing and Airway Assessment Using Polysomnography in Pediatric Patients With Craniofacial Disorders.

Children with cleft and craniofacial conditions commonly present with concurrent airway anomalies, which often manifest as sleep disordered breathing. Craniofacial surgeons and members of the multidisciplinary team involved in the care of these patients should appreciate and understand the scope of airway pathology as well as the proper means of airway assessment. This review article details the prevalence and assessment of sleep disordered breathing in patients with craniofacial anomalies, with emphasis on indications, limitations, and interpretation of polysomnography.

Granulomas of the membranous vocal fold after intubation and other airway instrumentation.

OBJECTIVES/HYPOTHESIS: We describe the clinical features of granulomas of the membranous vocal fold secondary to endotracheal intubation, bronchoscopy or esophagogastroduodenoscopy. STUDY DESIGN: Retrospective case series. METHODS: Review of cases at a single tertiary institution with evaluation of patient demographic characteristics, time to presentation, time to treatment, and clinical outcomes. RESULTS: Thirteen adult patients were identified with postintervention granuloma of the membranous vocal fold. All patients were female, with a mean age of 60 years (range, 28-81 years). None noted hoarseness prior to the intervention, and all noted significant hoarseness postoperatively. Conservative treatment with proton pump inhibitors and vocal rest was initially implemented in all patients. Four cases resolved without further intervention. Nine underwent surgical management because of airway symptoms, failure to improve, or patient request. One patient had injury to the contralateral vocal fold upon intubation. None experienced recurrence. Five had complete recovery of voice postoperatively, four did not. CONCLUSION: Iatrogenic granulomas of the membranous vocal fold after intubation or other upper airway instrumentation are rare complications presenting in the early postprocedure period with worsening hoarseness. Initial conservative treatment may be sufficient to yield resolution, and surgical treatment is effective for those failing medical management. Permanent voice damage may result from the original injury. LEVEL OF EVIDENCE: 4 Laryngoscope, 129:441-447, 2019.

Dacryocystorhinostomy with a thulium:YAG laser-a case series.

We conducted a retrospective chart review of 27 patients-7 men and 20 women, aged 47 to 94 years (mean: 71.3)-with symptomatic epiphora secondary to dacryostenosis who had undergone thulium: YAG (Tm:YAG) laser dacryocystorhinostomy (DCR). Among them, dacryostenosis had been documented in 35 eyes by dacryocystography. The Tm:YAG procedure involved the administration of local anesthesia, after which a 600-µm laser fiber was inserted into the lacrimal canaliculi and then into the nasolacrimal duct. Under endoscopic visualization, the DCR was performed anterior and inferior to the middle turbinate, which created an opening. Silicone stents were then inserted and tied intranasally. In the immediate postoperative period, all 27 patients noted initial improvement. During a follow-up of 22 days to 25 months (mean: 11.3 mo), 24 of the 27 patients (89%) remained symptom-free, while the remaining 3 patients (11%) experienced a treatment failure and required revision surgery. To the best of our knowledge, only two articles on thulium laser therapy for DCR have been previously published, both approximately 25 years ago; both involved the use of a thulium along with holmium and chromium in cadavers. As far as we know, our case series is the largest in the English-language literature that has documented the use of the thulium in laser therapy for DCR, and it is the only in vivo study. We found that DCR with the Tm:YAG laser was an effective and affordable option for patients with symptomatic epiphora secondary to lacrimal obstruction.

Cerebrospinal Fluid Fistula for the Craniofacial Surgeon: A Review and Management Paradigm.

Craniofacial surgeons perform operations that involve exposure of the dura. Typical procedures include cranial vault remodeling (CVR), fronto-orbital advancement (FOA), Le Fort III, monobloc, bipartition advancement, or distraction. Cerebrospinal fluid (CSF) fistulas remain one of the most common complications encountered, occurring in up to 30% of patients. Cerebrospinal fluid fistulas can be encountered intraoperatively, acutely, or in the late postoperative period. Traditional management has been well described in the neurosurgical literature. While several studies of complications exist, there is a relative lack of adequate information for craniofacial surgeons. The authors review current literature and provide 3 patients to illustrate our management paradigm.The authors review 30 years of experience at our institution and the pertinent literature. The mean rate of CSF fistula was 11.2%; rates were lowest for FOA/CVR, 5.5%. Patients with fistulas persisting after 2 days of conservative therapy or whom were symptomatic prompted placement of a lumbar subarachnoid catheter. Failure of the leak to resolve with CSF diversion prompted exploration and therapy which could include a patch, pericranial flap, and/or endonasal repair with septal flaps. Three patients are used to illustrate the paradigm, all of which have had no recurrence thus far.Cerebrospinal fluid fistula remains one of most common complications craniofacial surgeons encounter. Although neurosurgeons are often part of the clinical team, the craniofacial surgeon should be familiar with all aspects of treatment. Prompt diagnosis and appropriate knowledgeable management may avoid morbidity and mortality.

Nasal Septal Anatomy in Skeletally Mature Patients With Cleft Lip and Palate.

IMPORTANCE: Septal deviation commonly occurs in patients with cleft lip and palate (CLP); however, the contribution of the cartilaginous and bony septum to airway obstruction in skeletally mature patients is poorly understood. OBJECTIVES: To describe the internal nasal airway anatomy of skeletally mature patients with CLP and to determine the contributors to airway obstruction. DESIGN, SETTING, AND PARTICIPANTS: This single-center retrospective review included patients undergoing cone-beam computed tomography (CBCT) from November 1, 2011, to July 6, 2015, at the cleft lip and palate division of a major academic tertiary referral center. Patients met inclusion criteria for the study if they were at least 15 years old at the time of CBCT, and images were used only if they were obtained before Le Fort I osteotomy and/or formal septorhinoplasty. Twenty-four skeletally mature patients with CLP and 16 age-matched control individuals were identified for the study. MAIN OUTCOMES AND MEASURES: Septal deviation and airway stenosis were measured in the following 3 coronal sections: at the cartilaginous septum (anterior nasal spine), bony septum (posterior nasal spine), and midpoint between the anterior and posterior nasal spine. The perpendicular plate of the ethmoid bone and vomer displacement were measured as angles from the vertical plane at the coronal section of maximal septal deviation. The site of maximal septal deviation was identified. RESULTS: Among the 40 study participants, 26 were male. The mean (SD) age was 21 (5) and 23 (6) years for patients with CLP and controls, respectively. Septal deviation in patients with CLP was significantly worse than that of controls at the anterior nasal spine (2.1 [0.5] vs 0.8 [0.2] mm; P < .05) and posterior nasal spine (2.9 [0.5] vs 1.0 [0.3] mm; P < .01) and most severe at the midpoint (mean [SD], 4.4 [0.6] vs 2.1 [0.3] mm; P < .01). The point of maximal septal deviation occurred in the bony posterior half of the nasal airway in 27 of 40 patients (68%). The CLP bony angular deviation from the vertical plane was significant in the CLP group compared with the control group (perpendicular plate of the ethmoid bone, 14° [2°] vs 8° [1°]; vomer, 34° [5°] vs 13° [2°]; P < .05 for both), and vomer deviation was significantly associated with anterior nasal airway stenosis (r = -0.61; P < .01). CONCLUSIONS AND RELEVANCE: Skeletally mature patients with CLP have significant septal deviation involving bone and cartilage. Resection of the bony and cartilaginous septum should be considered at the time of definitive cleft rhinoplasty. LEVEL OF EVIDENCE: NA.

Prevalence of Voice Disturbances in the Pediatric Craniofacial Patient Population.

OBJECTIVE: To report on the prevalence of voice disturbances in the pediatric craniofacial population and to prove that the pediatric Voice Handicap Index (pVHI) is a useful questionnaire for this unique population. STUDY DESIGN: Case series with chart review. SETTING: Tertiary care center. SUBJECTS: Pediatric patients seen by a pediatric otolaryngologist in a craniofacial clinic. METHODS: Consecutive patients (N = 366) seen by a single pediatric otolaryngologist in a craniofacial clinic from July 2011 to September 2012 were included. Any patient specifically referred for airway problems or voice difficulties completed a pVHI questionnaire. Patients each underwent an evaluation including flexible fiberoptic laryngoscopy and videostroboscopy. Voice disturbance was further characterized into dysphonia, hypernasality, or hyponasality. RESULTS: Of all the patients evaluated, 280 (77%) were specifically referred for airway problems or voice disturbance. Of those referred, 39 (10.7%) were found to have an organic vocal fold pathology causing dysphonia, as seen on the videostroboscopic examination; 53.7% of these lesions were attributable to potential iatrogenic causes. Hypernasality and hyponasality were seen in 116 (31.7%) and 78 (21.3%) patients, respectively. The pVHI was 3.95, 26.3, 11.34, and 10.53 for those with no voice disturbance, dysphonia, hypernasality, and hyponasality, respectively. CONCLUSION: Pediatric patients with craniofacial disorders have a higher prevalence of dysphonia than the general pediatric population. The majority of causes of dysphonia in these patients are possibly iatrogenic in origin. The pVHI serves as a useful questionnaire in this unique patient cohort to quantify the disability from not only dysphonia but also hypernasality and hyponasality.

A complication of tracheobronchopathia osteochondroplastica presenting as acute hypercapnic respiratory failure.

BACKGROUND: Tracheobronchopathia osteochondroplastica is a rare benign and often indolent disease. We report the first case of tracheobronchopathia osteochondroplastica (TBO) presenting as acute hypercarbic respiratory failure due to superimposed subglottic submucosal abscess. CASE REPORT: A 27-year-old man presented to the emergency department in respiratory distress that required mechanical ventilation for acute hypercarbic respiratory failure. Upon extubation the next day, stridor was elicited with ambulation. Spirometry revealed fixed upper airway obstruction. Neck imaging showed a 2.8 × 2.0 × 4.0 cm partially calcified subglottic mass with cystic and solid component obstructing 75% of the airway. Surgical exploration revealed purulent drainage upon elevation of the thyroid isthmus and an anterolateral cricoid wall defect in communication with a subglottic submucosal cavity. Microbiology was negative for bacteria or fungi. Pathology showed chondro-osseous metaplasia compatible with tracheobronchopathia osteochondroplastica (TBO). The patient received a course of antibiotics and prophylactic tracheostomy. Since tracheostomy removal 3 days later, the patient remains asymptomatic. CONCLUSIONS: Tracheobronchopathia osteochondroplastica is a rare disease with usually benign clinical course and incidental diagnosis. It may present as acute hypercarbic respiratory failure when subglottic infection is superimposed.

Lymphatic malformations of the airway.

OBJECTIVES/HYPOTHESIS: To characterize the anatomic distribution of lymphatic malformations of the upper airway. STUDY DESIGN: Case series with chart review. SETTING: Tertiary care referral center specializing in the diagnosis and treatment of vascular anomalies. METHODS: A 7-year (2004-2011) retrospective chart review of patients with lymphatic malformations was performed at a tertiary care referral center. Patients with airway lymphatic malformations were identified. The anatomic distribution of lymphatic malformations within the airway was reviewed. RESULTS: A total of 141 patients with lymphatic malformations of the upper aerodigestive tract (UADT) were studied. Of these, 15 (11%) had laryngeal (supraglottic) involvement. In all of these patients, the disease was above the true vocal folds. Seventy-four (52%) patients had involvement of 1 anatomic zone (most common was the oral cavity), and 67 (48%) had involvement of multiple zones. With regard to each zone, 105 (75%) patients had involvement of the oral cavity, 50 (36%) the oropharynx, 8 (6%) the hypopharynx, 42 (30%) the parapharynx, and 12 (9%) had retropharygeal disease (some patients had multiple zones involved). No patients were identified with glottic, subglottic, or tracheal involvement. CONCLUSIONS: Based on our large series, airway involvement in head and neck lymphatic malformations may occur at multiple sites above the glottis. A high percentage of these patients have involvement of the oral cavity (75%) and oropharynx (35%). None involve the glottis, subglottis, or trachea.

Laryngeal manifestations of relapsing polychondritis and a novel treatment option.

OBJECTIVES: Laryngotracheal involvement in relapsing polychondritis (RP) is rare. However, it is one of the most common causes of death in this patient population. We present three patients who primarily presented with laryngeal manifestations of RP and a novel treatment option for bamboo nodules. STUDY DESIGN: Retrospective chart review and comprehensive review of the literature. RESULTS: Two patients first presented to an otolaryngologist because of hoarseness and chronic cough that eventually progressed to dyspnea upon exertion. Laryngeal examination revealed subglottic stenoses. Upon rheumatologic workup both were diagnosed with RP. After treatment with steroids and immunosuppressive drugs, one of the patient's laryngeal symptoms improved, whereas the other required dilation procedures. Neither patient had classic auricular or nasal symptoms upon initial presentation. The third patient was being treated for spasmodic dysphonia and was noted to have bamboo nodules with accompanying dysphonia. Rheumatologic workup revealed RP and systemic treatment ensued. Unfortunately, her symptoms of hoarseness persisted despite systemic treatment. A pulsed-potassium-titanyl-phosphate (KTP) laser was applied to the bilateral bamboo nodules, which eventually caused resolution of her vocal fold lesions and dysphonia. CONCLUSIONS: We present three patients with RP, all of whom sought health care by an otolaryngologist primarily. Awareness of this disease entity and the possibility for early laryngeal involvement is crucial for proper care of those with this life-threatening disease.

Cystic fibrosis and endoscopic sinus surgery: Relationship between nasal polyposis and likelihood of revision endoscopic sinus surgery in patients with cystic fibrosis.

OBJECTIVES: To observe the extent of nasal polyposis endoscopically in a cystic fibrosis population before the first surgical intervention and to grade the extent using a modified Malm scale, to observe patients prospectively and record the need for revision endoscopic sinus surgery (ESS), and to compare this among the individual polyp grading groupings. DESIGN: Retrospective medical record review of data collected prospectively. SETTING: Tertiary care hospital. PATIENTS: Forty-nine consecutive patients with a clinical preoperative diagnosis of cystic fibrosis and sinusitis. MAIN OUTCOME MEASURES: Using a modified Malm scale, the extent of polyps was prospectively graded into 3 groups before the first surgical intervention. The number of patients needing revision ESS and the mean time to revision ESS were compared among the 3 groups. RESULTS: Forty-nine consecutive patients underwent ESS between 1992 and 2007. We used a 3-stage system for extent of polyposis: 16 patients were noted to have no polyps (grade A), 14 had mild polyposis (grade B), and 19 had extensive polyposis (grade C). During the study, 14 patients required revision surgery: 3 with mild polyps and 11 with extensive polyps. Mean time to revision surgery was 39.7 months for those with grade B and 23.8 months for those with grade C. In the overall statistical analysis, the rate of revision ESS was significantly different among the 3 groups (P < .001). In pairwise comparisons, there were significant differences between those with grades A and C (P < .001) and between those with grades B and C (P = .04) and a trend toward significance between those with grades A and B (P = .052). There were no complications from ESS. CONCLUSION: Preoperative grading of nasal polyposis in patients with cystic fibrosis can help assess the future likelihood of revision ESS.

Duration-related efficacy of postoperative antibiotics following pediatric tonsillectomy: a prospective, randomized, placebo-controlled trial.

OBJECTIVE: To determine whether a 3-day course of postoperative antibiotics is as effective as a 7-day course in reducing pain and reducing time to resumption of a normal diet and level of activity following pediatric tonsillectomy. DESIGN: A prospective, randomized, placebo-controlled trial. SETTING: Academic medical center. PATIENTS: Forty-nine patients were enrolled in the study. Preoperative demographic information was obtained. INTERVENTIONS: Tonsillectomy with or without adenoidectomy was performed by the senior author (J.J.) using electrocautery. Patients were randomized to receive either a 3- or 7-day course of amoxicillin. MAIN OUTCOME MEASURES: Parents were asked to record the following information: analgesic use for the first 7 postoperative days, postoperative days the child initiated his or her usual diet and level of activity, and medical treatment for oral hemorrhage or dehydration. RESULTS: Of the 49 patients, 26 were randomized to receive 7 days of postoperative antibiotics (group A) and 23 to receive 3 days of antibiotics, followed by 4 days of placebo (group B). Results were obtained for 47 of the enrolled patients (96%). No statistically significant difference was noted between the 2 groups with regard to postoperative pain or time to resumption of a normal diet and level of activity. CONCLUSION: A 3-day course of antibiotics following pediatric tonsillectomy is as effective as a 7-day course with regard to postoperative analgesic use and resumption of normal diet and level of activity.

Synechia formation after endoscopic sinus surgery and middle turbinate medialization with and without FloSeal.

BACKGROUND: The aim of this study was to determine the incidence, outcomes, and risk factors for synechia formation after endoscopic sinus surgery (ESS) and middle turbinate medialization with and without FloSeal. METHODS: A retrospective review was performed of patients who underwent primary ESS with middle turbinate medialization, with or without the placement of FloSeal. Medialization was performed with the placement of an absorbable conchopexy suture and silastic splint. Operative variables and outcomes were analyzed to identify risk factors for synechia formation. RESULTS: One hundred thirty-five patients underwent medialization alone and 37 patients underwent medialization with placement of FloSeal. Overall, synechia formation was noted in 16 patients (9.3%). A statistically significant higher incidence of synechia formation was noted in patients who underwent middle turbinate medialization with the placement of FloSeal versus medialization alone (18.9% versus 6.7%). The incidences of intraoperative complications (6.2% versus 4.7%) and postoperative complications (6.2% versus 7%) were similar between patients with and without synechia, respectively. Patients experiencing synechia, however, underwent a statistically significant higher rate of revision procedures (25% versus 5.1%). CONCLUSION: Despite adequate prevention with middle turbinate medialization, synechia formation after ESS may result in higher rates of revision procedures. The placement of FloSeal in conjunction with middle turbinate medialization may result in a higher incidence of synechia formation.

Quality of life and complications following image-guided endoscopic sinus surgery.

OBJECTIVES: To compare the quality of life (QOL) outcome and incidence of complications following image-guided versus non-image-guided endoscopic sinus surgery (ESS). STUDY DESIGN: The operative, office, and hospital charts of patients who underwent primary ESS for chronic sinusitis by a single surgeon with (2002-2005) or without (1997-2002) image guidance were reviewed for patient demographics, incidence of complications, and revision procedures. A telephone survey was used to administer the QOL survey to both cohorts. RESULTS: In comparing patients who underwent image-guided (60) versus non-image-guided surgery (179), respectively, there was no statistically significant difference in the incidence of major intraoperative complications (6.6% vs 5.6%), major postoperative complications (5% vs 3.9%), revision procedures (6.6% vs 7.3%), and postoperative SNOT-20 symptom scores (23.6 vs 23.4). A higher incidence of intraoperative cerebrospinal fluid leak was noted in the non-image-guided group (0% vs 2.2%). CONCLUSIONS: Our study does not demonstrate an improvement in the incidence of complications, need for revision procedures, or quality-of-life outcome for patients undergoing primary ESS for chronic sinusitis. The use of image guidance may result in a lower incidence of skull base trauma and cerebrospinal fluid leak. EBM RATING: B-2b.
