Iatrogenic Rhinolith: A Case Report and Review of Literature.

INTRODUCTION: Unilateral nasal obstruction is a common complaint with a broad differential diagnosis that includes anatomic asymmetry, unilateral infective or inflammatory conditions, and benign and malignant sinonasal masses. A rhinolith is an uncommon foreign body in the nose, which serves as a nidus for calcium salt deposition. The foreign body can be endogenous or exogenous in origin and may remain asymptomatic for many years before incidental discovery. When left untreated, stones may cause unilateral nasal obstruction, rhinorrhea, nasal discharge, epistaxis or, in rare cases, progressive destruction leading to septal/palatal perforation or oro-antral fistula. Surgical removal is an effective intervention with limited complications reported. CASE REPORT: This article describes a 34-year-old male who presented to the emergency department (ED) with unilateral obstructing nasal mass and epistaxis, which was found to be an iatrogenic rhinolith. Successful surgical removal was performed. CONCLUSION: Epistaxis and nasal obstruction are common presentations to the ED. Rhinolith is an uncommon clinical etiology that if left undiagnosed may lead to progressive destructive disease; it should be included in the differential for any unilateral nasal symptoms of unclear origin. Appropriate work-up for any suspected rhinolith includes computed tomography, as biopsy is risky given the broad differential of unilateral nasal mass. When identified, surgical removal has a high success rate with limited complications reported.

The Modified Medial Maxillectomy as a Radical or Extended,-yet Still Functional,-Technique in Sinus Surgery.

BACKGROUND: Endoscopic sinus surgery with a middle meatal antrostomy is a common intervention in the treatment algorithm for maxillary sinus pathologies. However, this procedure has its origins in a time when simple ventilation of the sinus cavity was the primary (and only often) goal of surgery. In some patients, persistent mucociliary dysfunction occurs despite ventilatory surgery. Although the endoscopic modified medial maxillectomy (MMM) was originally described for tumour surgery, it provides a radical yet still functional option to overcome chronic sinus dysfunction. OBJECTIVE: The goal of this study was to describe the functional status of a post-MMM sinus cavity. METHODS: A consecutive series of patients who underwent at least a unilateral MMM by three tertiary rhinologists were retrospectively reviewed. Prospectively collected data included patient demographics (including age, gender, smoking status and comorbidities), disease-specific factors, microbiology, and preoperative patient-reported symptoms based on the 22-item Sinonasal Outcome Test-22 (SNOT-22) and radiology. The primary outcome of the study was the presence of sinus dysfunction, defined by mucostasis or pooling on endoscopic examination at the last follow-up. Secondary outcomes included the need for revision surgery as a result of sinus dysfunction and the improvement in SNOT-22 score. RESULTS: A total of 551 medial maxillectomies (47.0% female, 52.9 ± 16.8 years) were performed. Very few patients experienced post-operative sustained mucostasis following MMM (10.2%) and even fewer required revision surgery (5.0%). Chronic obstructive pulmonary disease (odds ratio (OR) = 6.82, P < 0.002.) and asthma (OR = 2.48, P = 0.03) were associated with mucostasis. Patients who underwent an MMM experienced a notable postoperative improvement in SNOT-22 score (45.9 ± 23.7 (pre-op) vs. 23.6 ± 19.4 (post-op); paired t-test, P < 0.0001). CONCLUSION: The MMM, whether performed for access to pathology or with the intent to avoid mucous 'sumping' with the sinus, can provide a long-term functional maxillary sinus cavity with minimal morbidity.

Smell Preservation following Unilateral Endoscopic Transnasal Approach to Resection of Olfactory Groove Meningioma: A Multi-institutional Experience.

Introduction Olfactory groove meningiomas (OGMs) are often associated with loss of smell following resection. Loss of smell has a measurable impact on quality of life. Smell preservation has been previously described in open approaches for early stage or unilateral OGMs. Evidence of smell preservation in endoscopic approaches is lacking. Design A multi-institutional retrospective review was performed on consecutive patients who underwent unilateral endoscopic endonasal resection of OGM. A gross total resection was achieved with preservation of the contralateral olfactory cleft and bulb. Olfactory function was assessed with a six-point olfactory symptom score and the Sniffin' Sticks 12-item smell identification test (SS-12). Contralateral olfactory bulb volume was measured on postoperative magnetic resonance imaging. Results Four patients (age 42.0 ± 7.5, 75% female) were assessed. Olfactory function was assessed at 21.8 ± 5.6 months following surgery. All patients reported some degree of smell preservation (75% described a slight/mild impairment in smell or better). Olfactory identification was preserved with an SS-12 score of 9 ± 1.4 (anosmia defined as ≤6). The olfactory bulb volume was calculated to be 47.4 ± 15.9 mm 3 (normal >40 mm 3 ). Conclusion Smell preservation is possible following unilateral endoscopic endonasal resection of carefully selected OGM.

Fungal ball of the maxillary sinus and the risk of persistent sinus dysfunction after simple antrostomy.

BACKGROUND: Maxillary sinus fungal ball is a common cause of unilateral maxillary sinusitis. Fungal balls or mycetomas are primarily treated with surgery to remove the fungus. However, this assumes the pre-fungal ball sinus cavity was normal and post-surgery patients may suffer from mucostasis in the sinus cavity with persistent symptoms. It is proposed that fungal balls are potentially a feature of impaired mucus clearance as they are a pathology in their own right. METHODS: A case series of consecutive patients undergoing antrostomy for maxillary sinus fungal ball was performed. Patient factors including age, gender, smoking status, comorbidities (allergy, asthma, and reflux), disease specific factors including duration of symptoms, microbiology (bacterial co-infection, Gram-positive and/or Gram-negative) and preoperative radiologic findings (extent of sinus development, and neo-osteogenesis/bone thickness) were collected. The primary outcome was sinus function defined by evidence of a normal functioning maxillary sinus, with the absence of mucostasis or pooling, on endoscopic exam at three months, six months and last follow-up. Endoscopic evaluation of inflammation was also collected. RESULTS: 28 patients (age 58.5 ± 15.5 years, 64.3% female) were assessed. Mucostasis was present at three months in 39.3%, at six months in 32.1%, and 17.9% at last follow-up. There was no comorbidity or radiologic finding that was associated with failure to normalize. Those patients with mucostasis had a higher modified Lund-Mackay endoscopic score at last follow-up (5.0 ± 0.7 v 0.2 ± 0.6, p < 0.01). CONCLUSIONS: Long term post-operative mucostasis occurred in 17.9% of patients following an adequate maxillary antrostomy for treatment of a fungal ball. Patients with mucostasis had persistent mucosal inflammation and a greater need for further surgery (modified medial maxillectomy).

The Effects of Lateral Crural Tensioning with an Articulated Alar Rim Graft Versus Lateral Crural Strut Graft on Nasal Function.

Importance: Nasal valve dysfunction can be addressed by various valve reinforcement techniques. There is no consensus on which technique is most efficacious. Objective: To evaluate lateral crural tensioning with articulated alar rim grafting (LCT/AARG) versus the lateral crural strut graft (LCSG) for their efficacy as nasal valve reinforcement techniques in rhinoplasty. Design, Setting, and Participants: A cohort study was undertaken on patients who underwent either the LCT/AARG or LCSG as part of their rhinoplasty procedure. Airway testing was performed preoperatively and 6 months after the procedure, with data collected from February 2015 to July 2018 at a single tertiary rhinologic practice. Consecutive adults underwent open structure septorhinoplasty by one surgeon for both cosmetic and functional indications, as both primary and revision cases. Main Outcomes and Measures: The primary functional outcomes analyzed were the nasal peak inspiratory flow (NPIF) and total nasal airway resistance (NAR). The primary patient-reported outcome measures analyzed were the visual analogue scale (VAS) for nasal obstruction, the Nasal Obstruction Symptom Evaluation (NOSE), and nasal obstruction score. Data were also normalized as a percentage improvement over preoperative baseline, to account for individual variability. Results: In total 94 participants were recruited (33.7 ± 11.7 years, 85.3% female) with 26.6% in the LCT/AARG group and 73.4% in the LCSG group. Change in NAR (ΔNAR) was significantly better in the AARG group (-18.73 ± 26.84 Pa/cc3 vs. 15.07 ± 55.57 Pa/cc3, p < 0.001). In addition, NAR improved significantly when analysis was isolated to the LCT/AARG group (0.414 ± 0.255 Pa/(cc3·s) vs. 0.291 ± 0.116 Pa/(cc3·s), Δ = -0.122 Pa/(cc3·s), p = 0.004) despite change in NAR being insignificant for the entire study population after surgery (0.370 ± 0.177 Pa/(cc3·s) vs. 0.349 ± 0.152 Pa/(cc3·s), Δ = 0.021, p = 0.320). There were no significant differences between the study groups in ΔNPIF (15.85 ± 31.48 L/min vs. 8.20 ± 30.12 L/min, p = 0.285), ΔVAS (35.77 ± 130.52 vs. 31.38 ± 73.19, p = 0.838), ΔNOSE (-73.60 ± 25.43 vs. -27.31 ± 123.44, p = 0.085), and Δnasal obstruction (64% experiencing improvement vs. 63.2% experiencing improvement, p = 0.097). Conclusions and Relevance: LCT/AARG demonstrated benefit in total NAR over the LCSG. There were no other significant functional differences between the two techniques.

Turbinate loss from non-inflammatory sinonasal surgery does not correlate with poor sinonasal function.

OBJECTIVE: The impact of turbinate resection on nasal function remains a controversial topic. In surgery for inflammatory sinonasal disease, turbinate resection is often avoided. In contrast, turbinate tissue is routinely sacrificed in endoscopic tumor and skull base surgery to achieve negative margins or gain adequate exposure. Anecdotally, these patients experience good self-reported post-operative nasal function despite extensive turbinate tissue loss. This study investigates the impact of turbinate resection on self-reported sinonasal function following endoscopic tumor or skull base surgery. STUDY DESIGN: Retrospective case series. SETTING: Tertiary Australian Hospitals. SUBJECTS AND METHODS: A retrospective review was performed on consecutive post-surgical patients after management for non-inflammatory sinus disease such as tumor resection or endoscopic skull base reconstruction. Outcome variables assessed included a 6-point Likert score for nasal obstruction, a 13-point Likert score for global nasal function and a 5-question sleep score. The degree of turbinate tissue loss (0-4) was determined by the number of inferior or middle turbinate subtotal resections. Regression analysis was performed, accounting for the effect of relevant demographic variables (smoking; asthma; allergic status; gastroesophageal reflux; malignancy; vestibule mucositis) and treatment variables (subtotal septectomy; Draf III; nasal radiotherapy.) RESULTS: 294 patients (age 52.9 ±â€¯17.6 years, 51.0% female) were assessed. Number of turbinates resected was not associated with poorer nasal obstruction score, global nasal function score or sleep score (OR = 1.77[0.93-3.38], OR = 0.60[0.33-1.12], B = 0.56[-1.58-2.69] respectively). Allergy and Draf3 were found to improve postoperative global nasal function score (OR = 2.07[1.04-4.13], P = 0.04, OR = 3.97[1.08-14.49], P = 0.04, respectively). CONCLUSION: In patients where surgery was performed for non-inflammatory sinus disease, turbinate resection is not correlated with poorer postoperative nasal obstruction, sinonasal function nor sleep quality.

Health Impairment From Nasal Airway Obstruction and Changes in Health Utility Values From Septorhinoplasty.

IMPORTANCE: The association of nasal airway obstruction with health is significant, and the health care resources utilized in open septorhinoplasty need to be included in health economic analyses. OBJECTIVES: To describe the association of nasal airway obstruction and subsequent open septorhinoplasty with patient health. DESIGN, SETTING, AND PARTICIPANTS: A prospective case series study was conducted from September 30, 2009, to October 29, 2015, at 2 tertiary rhinologic centers in Sydney, Australia, among 144 consecutive adult patients (age, ≥18 years) with nasal airway obstruction from septal and nasal valve disorders. INTERVENTIONS: Open septorhinoplasty. MAIN OUTCOMES AND MEASURES: Patients were assessed before undergoing open septorhinoplasty and then 6 months after the procedure. Health utility values (HUVs) were derived from the 36-Item Short Form Health Survey. Nasal obstruction severity was also measured using the Nasal Obstruction Symptom Evaluation (NOSE) questionnaire and the Sino-Nasal Outcome Test 22 questionnaires. RESULTS: A total of 144 patients (85 women and 59 men; mean [SD] age, 38 [13] years) were assessed. The baseline mean (SD) HUV for patients in this study was 0.72 (0.09), which was below the weighted mean (SD) Australian norm of 0.81 (0.22). After open septorhinoplasty, the mean (SD) HUV improved to 0.78 (0.12) (P < .001). Improvements in HUV were associated with changes in disease-specific patient-reported outcome measures, including Nasal Obstruction Symptom Evaluation scores (r = -0.48; P = .01) and Sino-Nasal Outcome Test 22 scores (r = -0.68; P = .01). CONCLUSIONS AND RELEVANCE: Patients with nasal airway obstruction reported baseline HUVs that were lower than the Australian norm and similar to those in individuals with chronic diseases with significant health expenditure. There was a clinically and statistically significant improvement in HUVs after open septorhinoplasty that was associated with a reduction in Nasal Obstruction Symptom Evaluation and Sino-Nasal Outcome Test 22 scores. Outcomes from this study may be used for health economic analyses of the benefit associated with open septorhinoplasty. LEVEL OF EVIDENCE: 4.

Patient-reported olfaction improves following outside-in Draf III frontal sinus surgery for chronic rhinosinusitis.

OBJECTIVES: The Draf III frontal sinusotomy is an established surgical procedure with an important role in the surgical management of recalcitrant chronic rhinosinusitis (CRS). In 2012, the outside-in approach to the Draf III was described as a safe and efficient procedure. Smell recovery in inflammatory CRS is challenging, and to date there is limited evidence suggesting that Draf III improves patient-reported olfactory dysfunction from CRS. METHODS: A consecutive series of patients who underwent an outside-in Draf III for inflammatory CRS by a single, tertiary rhinologist were reviewed. Patients were excluded if the Draf III was performed for noninflammatory conditions. Postoperatively, patients were maintained on long-term corticosteroid irrigations, and adherence was assessed. Prospectively collected data included patient demographics, a visual analogue scale for smell, overall Sinonasal Outcome Test Score (SNOT-22), global nasal function score, and a clinician-graded clinical outcome score. RESULTS: One hundred and four patients (41.1% female) aged 54 ± 12 years underwent an outside-in Draf III. The median follow-up time was 30.6 months (range 12.2-72.1). The majority of patients rated their smell loss as moderate or worse preoperatively; however, this was significantly improved at postoperative review (71.2% vs. 27.6%; Kendall tau-b, P < 0.01). The SNOT-22 score improved after surgery (2.32 ± 1.09 vs. 0.78 ± 0.69, P < 0.0001). Medication adherence was significantly associated with improved clinical outcome score (Kendall tau-b, P < 0.004). Aspirin exacerbated respiratory disease was found to be a significant risk factor predicting poor clinical outcome on univariate analysis (Odds Ratio = 4.69 (1.03-21.2), P = 0.04). CONCLUSION: The outside-in Draf III appears to facilitate sustained, meaningful improvement in several self-reported outcomes, including smell. However, further study and comparison to less aggressive surgery will be required to confirm its true benefit. LEVEL OF EVIDENCE: Level 4 Laryngoscope, 129:25-30, 2019.

Septal Perforation Repair Utilizing an Anterior Ethmoidal Artery Flap and Collagen Matrix.

BACKGROUND: Nasal septal perforation repair remains a challenge with no standard technique for repair recognized. OBJECTIVE: To describe the combination of an anterior ethmoidal artery flap with a collagen matrix inlay as a successful technique for nasal septal perforation repair. METHODS: A case series of consecutive patients who underwent nasal septal perforation repair with an anterior ethmoidal artery flap with an inlay collagen graft was conducted. Demographic data, preoperative features of the perforation (size, location, and presence of chondritis), and postoperative outcomes were analyzed; closure rate, mucosalization rate (of the contralateral side at 21 and 90 days), and complications (crusting, bleeding, obstruction, infection, and rehospitalization <30 days) were documented. RESULTS: Thirteen patients (age: 49 ± 15 years, 30.8% women) were assessed. The perforation size was 1.6 ± 0.9 cm (range: 0.3-3.5 cm) and located 1.2 ± 0.5 cm (range: 0.5-2.0 cm) posterior to the columella. Chondritis was present in 69.2%. The closure rate was 100% (95% confidence interval [CI]: 77%-100%) at both 21 and 90 days. One patient required a free mucosa graft to an area of persistent crusting on the contralateral side (7.7%). Complications were low; bleeding 0%, obstruction 7.7% (requiring corticosteroid injection of anterior ethmoidal artery flap), and 0% infection/rehospitalization. CONCLUSION: Anterior ethmoidal artery flap with an inlay collagen matrix is a reliable technique to repair nasal septal perforation. This technique, with robust vascularity and wide angle of rotation, enables the closure of perforations both large (<50% total septum) and with anterior locations.

The role of frontal sinus drillouts in nasal polyposis.

PURPOSE OF REVIEW: Historically, the common frontal sinusotomy has been reserved only for salvage frontal sinus surgery in patients with severely recalcitrant inflammatory sinus disease. By understanding the pathophysiology of inflammatory sinus disease and the long-term role of topical medication in their treatment, the indications for Draf3 have expanded. RECENT FINDINGS: A major therapeutic impact from endoscopic sinus surgery for inflammatory sinus disease is imparted by allowing sinus access to topical therapies to work. Although traditionally, the Draf3 frontal sinus procedure has been reserved for revision surgery in severe cases, advancements in technology, instrumentation, and techniques has allowed the Draf3 to evolve to efficient and safe procedure, often applied primarily in select patients. There is evidence to support the indication for Draf3 in primary surgery for severe cases. SUMMARY: In inflammatory sinus disease, the goal of endoscopic sinus surgery is to convert the complex and limited frontal sinus outflow tracts into a simple common cavity. This allows for local, topical anti-inflammatory treatments to control the disease. When patients have broader inflammatory airway disease and asthma, the Draf3, as part of a neo-sinus cavity, is commonly applied early in surgical care.

Long-term follow-up of a patient with malignant transformation of inverted papilloma into sinonasal undifferentiated carcinoma.

INTRODUCTION: Inverted papillomas (IP) are benign sinonasal neoplasms, which account for 0.5-4% of all nasal tumors. IPs have been known to transform into squamous cell carcinoma in 5-15% of cases. Rarely, transformations to other malignancies have been reported. Here we report a unique case of malignant transformation of an IP into sinonasal undifferentiated carcinoma (SNUC). METHODS: A case report with a literature review; institutional review board exempted. The clinical presentation, radiographic features, surgical intervention, histopathologic analysis, treatment, and outcome of the case were examined. RESULTS: A 62-year-old man presented with a 3-month history of nasal airway obstruction, rhinorrhea, and postnasal drip refractory to medical therapy. He had a long history of exposure to fumes, chemicals, dusts, and solvents as a professional painter as well as a 45 pack-year history of smoking and alcohol abuse. The patient was ultimately found to have a left ethmoidal IP with a focus of malignant transformation into SNUC. Endoscopic resection was performed, followed by concurrent chemoradiation and adjuvant chemotherapy. After surgery, he had no evidence of recurrent disease after 9 years of follow-up. CONCLUSIONS: IP is known to transform into squamous cell carcinoma. Here we report a rare case of malignant transformation into SNUC, a much more uncommon and aggressive lesion. Although traditionally associated with a poorer prognosis, the positive outcome for SNUC observed in this patient may potentially be attributed to early detection and timely therapeutic intervention.
