Comparison with efficacy and safety of the treatment with different operation approach under nasal endoscope in benign maxillary sinus lesions / 中国内镜杂志

Objective To explore the validity and security of treatment of different operation approach under nasal endoscope in patients with benign maxillary sinus lesions.Methods A retrospective analysis was performed on 80 patients with benign maxillary sinus lesions diagnosed and treated from January 2020 to January 2022,and they were divided into group A(n = 40)and group B(n = 40)according to the operative method.Group A was treated with middle nasal meatus combined with Caldwell-Luc operation under nasal endoscope,and group B was treated with middle nasal meatus antrostomy first and anterior lacrimal recess approach later under nasal endoscope.The clinical efficacy,operation index,visual analogue scale(VAS),Lund-Kennedy endoscopic score,adverse reactions and recurrence rate of both groups were compared before and after operation.Results The total effective rate was sensibly higher in group B than that in group A,the intraoperative blood loss was sensibly less in group B than that in group A,the operation and hospitalization time were sensibly shorter in group B than those in group A,6 months after operation,the VAS and Lund-Kennedy scores were sensibly decreased in comparison with those before operation,and group B was sensibly decreased in comparison with those in group A,the total incidence rate of adverse reactions and recurrence rate were sensibly lower in group B than those in group A,the differences were statistically significant(P＜0.05).Conclusion The surgical treatment of patients with benign maxillary sinus lesions through the middle nasal meatus and the anterior lacrimal recess approach under nasal endoscope is effective and can relieve the pain of patients with high safety.It is worthy of clinical application.

Compressive Trigeminal Neuropathy after Caldwell-Luc Operation

Most postoperative maxillary cysts develop more than 10 years after a Caldwell-Luc operation. They can manifest with cheek pain, swelling and dental and visual symptoms. Brain imaging should be performed to distinguish trigeminal nerve compression from various other possible causes. It should be treated by surgical intervention to relieve the above-mentioned symptoms. We report a patient who presented with compressive trigeminal neuropathy caused by a postoperative maxillary cyst.

Diagnosis and Treatment of Unilateral Maxillary Sinus Hypoplasia

Glucocorticoid Receptor-beta Overexpression According to Nasal Polyp Severity: Immunohistochemical Study

BACKGROUND AND OBJECTIVES: The aims of the study were to reintroduce a surgical technique for a "mini" Caldwell-Luc operation and to determine its efficacy. MATERIALS AND METHODS: A prospective study was performed in 23 patients undergoing the "mini" Caldwell-Luc operation. Improvements in clinical symptoms and endoscopic and computed tomographic (CT) findings were evaluated postoperatively over a follow-up period ranging from 6 to 21 months. All patients were surveyed for nasal symptoms (nasal obstruction, rhinorrhea, posterior nasal drip, headache, and anosmia), complications (tooth or gum pain, numbness, persistent facial pain, and facial hypo-paresthesia), and recurrence. Preoperative nasal polyps were classified by the Gaskins method, and preoperative paranasal sinusitis was graded according to the Kennedy CT staging system. RESULTS: Symptom scores were all significantly reduced postoperatively (paired t-test, p<0.05). There were no major complications specific to this technique. Among 29 maxillary sinuses that received the "mini" Caldwell-Luc operation, seven showed recurrence (24%). CONCLUSION: The "mini" Caldwell-Luc operation provides an alternative method of obtaining access to the maxillary antrum and is associated with minimal morbidity.

Treatment Results of 111 Cases of Antrochoanal Polyp

BACKGROUND AND OBJECTIVES: Antrochoanal polyp (ACP) is a benign maxillary sinus polyp that originates from the mucosa of the maxillary sinus, passes through the sinus ostium, and extends into the choana. Surgical methods employed in the treatment of antrochoanal polyp are simple avulsion, Caldwell-Luc operation, osteoplastic maxillary sinus operation, and endonasal endoscopic removal. In this study, we evaluated the clinical presentation of ACP and compared its surgical outcomes. MATERIALS AND METHODS: We retrospectively reviewed 111 patients who were treated for ACP between January 1995 and May 2008, and analyzed clinical features, radiologic findings, and surgical results. RESULTS: The study group consisted of 111 patients (65 males, 46 females) with a mean age of 20.0 years (range, 4 to 70). Sixty-one cases were accompanied by sinusitis (20 with unilateral sinusitis, 41 with bilateral sinusitis). Endoscopic sinus surgery (ESS) was used to treat 95 cases, and the external approaches of Caldwell-Luc operation or osteoplastic maxillary sinus operation were applied in 12 and four cases, respectively. Among those who received ESS, ACP recurred in 16 cases, whereas none of the patients who received the external approach showed recurrence. CONCLUSION: Endoscopic sinus surgery is a good alternative method for the treatment of ACP. If the antral part of ACP cannot be removed completely, an external approach such as Caldwell-Luc operation or osteoplastic maxillary sinus operation for pediatric patients may be considered to prevent recurrence.

Case report: Maxillary sinus aspergillosis

The incidence of aspergillosis infections in the maxillary sinus has increased recently, because of overuse of antibiotics, steroids, anticancer agents, immunosuppressant, antimetabollites, and uncontrolled diabetes mellitus. The clinical features of maxillary sinus aspergillosis include pain, swelling and foul odor nasal excretion. This needs to be differentiated from bacterial maxillary sinusitis, and surgical treatment with antifungal agents are suggested. Recently, we treated two patients with maxillary sinus aspergillosis surgically (Caldwell Luc operation) and with antifungal agents(itraconazole). The results were satisfactory so we report these cases with literature review.

Acute pulmonary edema caused by impaired switching from nasal to oral breathing during the caldwell-luc operation resulting from anesthesia: a case report

Nasotracheal intubation is performed routinely in maxillofacial surgery to optimize visualization of the surgical field. The CaldwellLuc operation is an approach to the maxillary sinus through the labiogingival sulcus and canine fossa. The operation is used to treat chronic maxillary sinusitis, and involves curettage of the mucosa of the maxillary sinus and the creation of an inferior meatal antrostomy. After the operation, a nasal Foley catheter is inserted into the inferior nasal meatus for the discharge of blood and tissue fluid. Then, the nostril is packed with vaseline gauze. Before the patients awaken, they experience impaired switching from nasal to oral breathing. Pulmonary edema can result from excessive negative intrathoracic pressure caused by acute airway obstruction in patients breathing spontaneously. During anesthesia and sedation, airway obstruction can occur at the levels of the pharynx and larynx. Even in patients who are awake, alteration in the ability to change the breathing route from nasal to oral may affect breathing in the presence of an airway obstruction, causing this catastrophic event. We experienced a case in which acute pulmonary edema resulted from acute airway obstruction triggered by the patient's inability to switch the breathing route from nasal to oral during emergence from anesthesia.

Objective:To investigate the clinical effect of surgical procedures on patients with chronic sinusi-tis. Method: 104 patients with chronic sinusitis were treated by endoscopic and Caldwell-Luc's approaches. Thelesions were cleared away completely. Result:The clinical cure rate was 96.1％ after 6～12 months (average 9months ) follow up. Conclusion:It suggests that patients with severe maxillary sinus diseases might be cured byendoscopic and Caldwell-Luc's procedure.

Fungal Sinusitis: Clinical Features and Treatment Outcomes with Emphasis on Endoscopic Sinus Surgery / 대한이비인후과학회지

BACKGROUND: Endoscopic sinus surgery has emerged as a successful surgical modality in the treatment of fungal sinusitis. In this study, we aimed to investigate the clinical characteristics of fungal sinusitis and evaluate the efficacy of endoscopic sinus surgery in comparison with Caldwell-Luc's operation for treating fungal sinusitis. MATERIALS AND METHODS: Sixty seven patients (69 cases) who underwent surgery between 1989 and 1996 were retrospectively analyzed by reviewing their medical records and X-ray films. The Caldwell-Luc's operation was applied for 37 cases, and the endoscopic sinus surgery was carried out for 32 cases. RESULTS: All patients were adults consisting of 27 males and 40 females. Of the 69 cases, aspergillosis was most common, followed by unidentifiable fungal colonies, mucormycosis, and candidiasis. Nasal obstruction was the most common symptom and those symptoms associated with fungal sinusitis were nonsepcific. Preoperative computerized tomograms (CT) revealed mottled calcific densities within the involved sinuses in 64.3% of cases and pathological examinations showed that all of these had fungal sinusitis. Of the 37 patients who underwent Caldwell-Luc's operation, two were of the invasive types, with one of them showing postoperative recurrence. The 32 patients who underwent endoscopic sinus surgery showed no recurrence during the mean follow-up period of 11.8 months. CONCLUSION: Our results suggest that the mottled calcific densities in the sinus CT could be used as a telltale sign of the fungal sinusitis and that the endoscopic surgical technique could replace Caldwell-Luc's operation for the treatment of noninvasive fungal sinusitis.

Caldwell-Luc's Operation with Middle Meatal Antrostomy / 第二军医大学学报

Fifty-nine patients (62 cases ) with chronic antritis were operated by Caldwell-Luc's operation with middle meatal antrostomy and followed up for 0.5 ~5 years. It was found that curative effect of the oper ation was quite well. Eghty patients treated with Caldwell-Lucs operation were followed up as control at the same time. Caldwell-Luc's operation with middle meatal antrostomy was found safe, easy to operate and not injurious to agger nasi, as well as partially recoverable to sinus function.
