Ann Med Surg (Lond) 2021; 65:102317. [PMID: 33981427 PMCID: PMC8085898 DOI: 10.1016/j.amsu.2021.102317] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Revised: 04/08/2021] [Accepted: 04/12/2021] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND During dacryocystorhinostomy (DCR), the lacrimal sac wall biopsy is not routinely performed in our hospital, but it is recommended if there is a suspicion of underlying disease other than preoperatively or intraoperatively chronic inflammation. OBJECTIVE Most of patients with epiphora have different causes of nasolacrimal duct obstruction (NLDO). This study aims to examine how important routine lacrimal sac biopsy is during endoscopic DCR surgery. PATIENTS & METHODS The study included 50 patients with chronic unilateral epiphora. All patients underwent endoscopic DCR with NLD biopsy. Histopathologic analysis was performed for each specimen. RESULTS The findings of NLD biopsy showed chronic inflammation in 33 cases (66%), chronic dacryocystitis in 9 cases (18%), dacryolith with dacryocystitis in one case, granuloma in 4 cases (8%), rhinoscleroma in 2 cases (4%), and one case had a neoplasm. Histopathologic findings were inflammatory cellular infiltrates in 56%, 30% and 14% in mild, moderate and severe chronic inflammatory state (CIS) score, respectively. Fibrosis in 18%, 20% and 62% in mild, moderate and severe CIS score, respectively. Capillary proliferation in 64%, 32% and 4% in mild, moderate and severe CIS score, respectively. Chronic inflammatory signs in 64%, 32% and 4% in mild, moderate and severe CIS score, respectively. CONCLUSION Although neoplasm and granuloma are rare cause of lacrimal sac or duct obstruction requiring DCR, they were detected through nasolacrimal assessment and routine intraoperative lacrimal sac biopsy.

The role of surgery in antineutrophil cytoplasmic antibody-associated vasculitides affecting the nose and sinuses: A systematic review. SAGE Open Med 2020; 8:2050312120936731. [PMID: 32676189 PMCID: PMC7340348 DOI: 10.1177/2050312120936731] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2019] [Accepted: 05/29/2020] [Indexed: 01/28/2023] Open
Abstract
Background: The ear, nose and throat region has been reported to be one of the commonest sites involved in antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis diseases and often precedes the diagnosis of ANCA–associated vasculitis by many months. Although treatment for ANCA–associated vasculitis primarily requires systemic immunosuppressive therapy, there are specific indications for sinonasal surgery during the course of the disease process. The three major roles for surgery in sinonasal vasculitis are to aid diagnosis through biopsy, enable symptom relief and nasal reconstructive surgery consideration when in remission. Purpose: The aim of this systematic review is to provide an overview of the surgical procedures which can be performed in patients with ANCA–associated vasculitis presenting with sinonasal involvement. Materials and methods: A systematic literature search was performed for scientific articles on MEDLINE (PubMed Advanced MEDLINE Search) and EMBASE. The search included all articles up to April 2020. Conclusion: Surgical intervention during the active phase of ANCA–associated vasculitis disease can improve the patient’s symptoms and enable histological diagnosis. The surgical decision to manage the nose requires a multidisciplinary approach involving the vasculitis specialist and the ear, nose and throat surgeon. Nasal reconstruction can be performed to restore form and function but only when the disease is in remission so as to maximise success and minimise complications.

[PMID: 32521057 DOI: 10.1002/lary.28795] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 05/10/2020] [Accepted: 05/14/2020] [Indexed: 11/08/2022]
Abstract
OBJECTIVES/HYPOTHESIS Revision endoscopic dacryocystorhinostomy (END-DCR) is the preferred approach for failed primary surgeries, yet quality data on long-term outcomes are lacking. This study aimed to evaluate three aspects of revision END-DCR: 5-year success rates, patient satisfaction, and the primary surgical approach's possible impact on revision. METHODS This retrospective study included all revision END-DCRs conducted at Kaplan Medical Center between the years 2002 and 2015. For long-term follow-up analysis, two subgroups of first and second revision END-DCRs with a minimum of documented 5-year follow-up after surgery were defined. Data were analyzed according to the primary surgical approach. Surgical success was defined by either anatomical (observed patent lacrimal flow) or functional (symptoms cessation) success. Patient satisfaction was measured by a questionnaire. RESULTS After exclusions, a total of 45 eyes from 38 patients who underwent revision END-DCR surgeries were included in the study. The yearly success rates from immediate to 5 years following the first revision were 93.3%, 75.5%, 71.1%, 68.9%, 68.9%, and 68.9% for the entire cohort, respectively. Immediate and 5-year success rates following the second revision were 88.8% and 77.8%, respectively. Primary END-DCR showed favorable 5-year success rates and patient satisfaction over primary external dacryocystorhinostomy (EXT-DCR) in both first and second revisions, but this did not reach significance. CONCLUSIONS Revision END-DCR carries an excellent short-term success rate, which decreases mainly throughout the first 2 years following surgery. Postoperative follow-up should be maintained within this timeframe. Revision END-DCR following either primary endoscopic or EXT-DCR produces comparable surgical outcomes and patient-reported satisfaction. LEVEL OF EVIDENCE 3b Laryngoscope, 131:E682-E688, 2021.

Abstract
The aim of this study is to assess the etiologic factors of primary dacryocystorhinostomy (DCR) failure according to DCR techniques and also to determine risk factors for the prediction of failure in revision external DCR. Retrospective review was performed in patients who underwent revision external DCR for previous DCR failure between 2008 and 2018. All patients underwent full ophthalmic and intranasal examination, lacrimal probing, and irrigation. Patients were classified into following groups according to previous DCR type: external, endoscopic endonasal, and transcanalicular laser DCR. Potential etiologic factors were compared between 3 groups. Multivariate analysis was performed to identify risk factors for failure in revision external DCR. About 115 eyes from 109 patients constituted the external (50.4%), endonasal (31.3%), and laser (18.3%) DCR groups. Among 27 (23.5%) patients with intranasal pathologies, septal deviation (33.3%) is the most common finding. The commonest cause of failure was inadequate ostium size in external (37.9%), endonasal (36.1%), and laser (66.7%) DCR groups. Inadequate ostium size and cicatricial lacrimal ostium scarring were observed significantly more common in the laser (P = 0.047) and external DCR group (P = 0.043), respectively. The success rate for revision external DCR was 85.2%. Canalicular or common canalicular obstruction (P = 0.032), intranasal pathology (P = 0.003), and bilateral obstruction (P = 0.025) demonstrated a significant independent association with failure in revision external DCR. Inadequate ostium size was the most common cause of failure in primary external, endonasal, and laser DCR. Canalicular or common canalicular obstruction, intranasal pathology, and bilateral lacrimal obstruction were significant predictors of failure in revision external DCR.

Abstract
Purpose To investigate the association of ptosis, levator, and jaw winking in Marcus Gunn jaw-winking synkinesis (MGJWS), and the risk factor of preservation and outcomes of the unilateral levator excision and frontalis suspension. Methods Clinical features of MGJWS case series from 2011 to 2018 were retrospectively reviewed. Association between jaw winking and ptosis/levator function was statistically analyzed. The patients underwent unilateral levator excision and frontalis suspension using silicone rod or autogenous fascia lata. Clinical outcomes were evaluated in operated patients and the independent risk factors of residual jaw winking were investigated after a long follow-up. Results There were 42 MGJWS patients in 2011 to 2018, accounting for 2.87% of all congenital blepharoptosis. 80% of mild jaw winking was accompanied with mild ptosis and fair levator function, and moderate-to-severe jaw winking was often accompanied with moderate-to-severe ptosis and poor levator function (P < 0.05). Ptosis showed a strong association with excursion of jaw winking (R = 0.785, P < 0.01). Jaw winking was resolved in all 34 operated patients with good correction of ptosis. Severity of jaw winking is an independent risk factor for the residual synkinesis after surgery. Severe preoperative jaw winking had an 18.05 times increased risk of postoperative residual synkinesis compared with moderate jaw winking (P < 0.05). Conclusions In MGJWS eyelid excursion of jaw winking has a direct correlation with ptosis and dysfunction of levator muscle. Unilateral levator aponeurosis excision and frontalis suspension is an efficient approach for MGJWS. Severe jaw winking is a risk factor of residual eyelid synkinesis after surgery.

Abstract
PURPOSE To evaluate the characteristics of bilateral nasolacrimal duct obstruction (NLDO) carriers and success rates of same day (simultaneous) or asynchronous (different day) bilateral dacryocystorhinostomy (DCR). METHODS This retrospective study included patients with bilateral NLDO who underwent bilateral external DCR between January 2010 to August 2015 at the King Khaled Eye Specialist Hospital, Saudi Arabia. Postoperative success rate was considered as subjective perception of no tearing bilaterally or failure if unilateral or bilateral tearing persists after surgery. Data were statistically analyzed with P <0.05 indicating significance. RESULTS Of 57 patients undergoing bilateral DCR, 32 (56%) had same-day surgeries and 25 underwent asynchronous surgery. The median duration of follow up was 7 months. The success rates were similar for the same day group [61.3%-95% CI 49.4-73.2)] and for the asynchronous group [54.2% (95% CI 40.4-68.0)]. Success rate was not correlated to the age, gender, or use of stents. CONCLUSIONS The authors strongly recommend bilateral same-day external DCR to treat bilateral NLDO since the success rate of the procedure is similar to the asynchronous surgery, allowing a full treatment in just 1 operative visit.

Abstract
PURPOSE To review and summarize the syndromic, nonsyndromic, and systemic associations of congenital lacrimal drainage anomalies. METHODS The authors performed a PubMed search of all articles published in English on congenital lacrimal anomalies (1933-2016). Patients of these articles were reviewed along with the literature of direct references to syndromes and other systemic associations. Data reviewed included syndromic descriptions, systemic details, demographics, lacrimal presentations, management, and outcomes. RESULTS Syndromic and systemic associations with congenital lacrimal drainage disorders are not known to be common. Although familial presentations have been reported, the inheritance patterns are unclear for most anomalies. There is an increasingly growing evidence of a genetic basis to many lacrimal anomalies. However, few syndromes have either widespread or are frequently associated with lacrimal anomalies. Few sequences of distinct lacrimal presentations and intraoperative findings are seen. Surgical challenges in these patients are distinct and a thorough pre and intraoperative anatomical assessment, detailed imaging when indicated, and assessment and correction of associated periocular and facial abnormalities may facilitate good outcomes. CONCLUSIONS Lacrimal drainage anomalies associated with syndromic and nonsyndromic systemic conditions have certain unique features of their own and their surgical and anesthesia challenges are distinct. Diagnosis of congenital lacrimal drainage anomalies should prompt consideration of the possible presence of associated systemic abnormalities.

Abstract
Transient nasolacrimal duct obstruction secondary to a mass lesion compressing the sac or sac-duct junction is rare. The authors report a case of a young female who presented to the authors with complaints of watering and a mass lesion in the lacrimal sac region. An organized perilacrimal mass filled with thick pultaceous material was noted during surgery. Following the drainage of the mass lesion, irrigation of the lacrimal system was freely patent. Microbiological examination and DNA sequencing targeting interspacer region was suggestive of Pleurostomophora richardsiae species. To the best of the authors' knowledge, this is only the second case report of a subcutaneous perilacrimal mass causing transient nasolacrimal duct obstruction by Pleurostomophora richardsiae.

Abstract
Purpose We report a very good outcome in a 44-year-old woman in whom cancer was missed as the cause of nasolacrimal duct obstruction and dacryocystitis and which was deemed inoperable after spreading to the cavernous sinus. Case Report The patient was referred to our unit 12 months following uneventful right dacryocystorhinostomy for nasolacrimal duct obstruction. This had been complicated by the formation of a significant canthal swelling 6 months later, which had been excised at that time. The symptom of nasolacrimal duct obstruction and scar recurrence prompted the referral to our unit. Examination and biopsy confirmed a malignancy. Despite extensive surgery, including concurrent radical neck dissection and parotidectomy, within 6 months, her mucoepidermoid carcinoma was found to have spread to the cavernous sinus, restricting blood flow from the carotid and causing an abducens nerve palsy. Though deemed inoperable at first, Gamma Knife stereotactic radiosurgery was sought as treatment for her disease, resulting in a good outcome 4 years after surgery. Conclusion Experience from this case suggests the importance of considering malignancy as a cause in young patients when presenting with nasolacrimal duct obstruction. In such cases, and perhaps for all patients, biopsy specimens should be submitted as many tumours are found incidentally at the time of dacryocystorhinostomy. Whilst the external approach to dacryocystorhinostomy may identify abnormal anatomy intraoperatively, prompting biopsy, this is less likely with an endonasal approach where osteotomy precedes sac visualisation. The endonasal approach may therefore be less appropriate in such cases where malignancy is suspected as osteotomy may aid in the spread.

Chonnam Med J 2015; 51:19-25. [PMID: 25914876 PMCID: PMC4406990 DOI: 10.4068/cmj.2015.51.1.19] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2015] [Revised: 03/14/2015] [Accepted: 03/16/2015] [Indexed: 12/28/2022] Open
Abstract
The current study aimed to determine the efficacy of probing with adjunctive mitomycin C (MMC) as a treatment for nasolacrimal duct obstruction (NLDO) in adults and to study the association of probing success with demographic and obstruction characteristics. This was a prospective, randomized, double-blind, placebo-controlled trial including 140 patients (each with a unilateral NLDO) scheduled for nasolacrimal probing who were randomly assigned to receive MMC (0.2 mg/ml, 70 patients; group A) or placebo (normal saline, 70 patients; group B). Irrigation was carried out with 0.5 cc of MMC (0.2 mg/mL) in the duct with a nasal pack for 10 minutes in group A. Patients' postprobing epiphora was evaluated at 2 weeks and 1, 3, 6, and 9 months postoperatively. Probing was judged to be a success if there was no or mild watering for at least 9 months after the procedure. There were no significant differences between the two study groups in demographic characteristics or duration of the operation (p=0.062). The overall success rate of probing with MMC was 47/70 (67.1%), which was significantly higher than the success rate of the procedure with placebo (p=0.0027). When the sex of the patients was controlled for by logistic regression, a significant association between the failure rate of probing and increasing age was found in cases and controls (p=0.004 vs. p=0.006, respectively). No significant side effects of probing with MMC were noted after 9 months of follow-up. Administering MMC in a dosage of 0.2 mg/mL during nasolacrimal probing significantly increased the success rate of probing. The failure rate of probing increased with age. A low dose of MMC is cheap, safe, and easily accessible; thus, it is recommended during nasolacrimal probing, especially in patients who refuse dacryocystorhinostomy surgery.
