Study on Endoscopic Approach for Sinonasal Inverted Papilloma

Objectives: The purpose of this study is to evaluate the endoscopic approach for sinonasal inverted papilloma and outcome of the surgical management. Study design: Retrospective. Place and duration of study: Dhaka Medical college Hospital and Bangladesh ENT Hospital Ltd. of Bangladesh, from January 2006 to December2020. Materials and methods: 189 cases of Inverted papillomas (confirmed by histopathology) presented in last 15 years were managed by Endoscopic Sinus Surgery and the outcome evaluated. Results: The age of the patients ranged from 41 to 80 years. The mean age was 60 years with Male Female ratio 2.04:1.165 patients had unilateral disease and 24 patients had bilateral. Hundred & seventy two patients with inverted papilloma resected by the endoscopic approach,09 patients by nasoendoscopy in combination with modified Caldwell-Luc approach and 8 patients by combined external and nasoendoscopic approach. Follow up revealed recurrence in nine patients. Conclusion: Findings suggest that endoscopic approach is a safe and effective way of treating sinonsal inverted papilloma. Most lesions were entirely resected through endoscopic approach. Importantly surgical strategies need to be thoughtfully chosen based on tumor stage to achieve maximum removal of the lesion and prevent recurrence.

Caldwell Luc in the era of endoscopic approach for maxillary sinus

Caldwell Luc is a historical procedure for the maxillary sinus, which is more than 100-year-old and is still a useful procedure of choice among surgeons in certain maxillary sinus pathologies. In the era of endoscopic sinus surgeries, the usefulness of Caldwell Luc is often questioned. We report two cases of chronic maxillary sinus disease one with an iatrogenic tooth root in the sinus for 2 years and the other with a mucosal polyp both of which were managed endoscopically earlier but with recurrence of symptoms. Both the cases were managed using a modified Caldwell-Luc approach. The patients were asymptomatic postoperatively with no recurrence.

Maxillary sinus augmentation using biphasic calcium phosphate: dimensional stability results after 3-6 years.

PurposeThis study was designed to observe the resorption pattern of biphasic calcium phosphate (BCP) used for maxillary sinus augmentation over a 3- to 6-year healing period, and to investigate factors affecting the resorption of BCP.MethodsA total of 47 implants placed in 27 sinuses of 22 patients were investigated. All patients had residual bone height less than 5 mm at baseline. The modified Caldwell-Luc approach was used to elevate the maxillary sinus membrane, and the sinus cavity was filled with BCP (70% hydroxyapatite and 30% β-tricalcium phosphate). Implant placement was done simultaneously or in a staged manner. Serial radiographic analysis was performed up to 6 years postoperatively.ResultsDuring the follow-up period, no implant loss was reported. The mean reduced height of the augmented sinus (RHO) was 0.27±1.08 mm at 36 months, and 0.89±1.39 mm at 72 months postoperatively. Large amounts of graft material (P=0.021) and a long healing period (P=0.035) significantly influenced the amount of RHO. In particular, there was a significant relationship between a healing period longer than 40 months and RHO.ConclusionsBCP can achieve proper dimensional stability with minimal reduction of the graft height in a 3- to 6-year healing period after maxillary sinus augmentation. The healing period and the amount of graft material influenced the resorption of BCP.

Endoscopically Assisted Modified Caldwell-Luc Approach to Enucleation of Dentigerous Cyst With Ectopic Tooth From the Maxillary Sinus

Dentigerous cysts in the craniomaxillofacial complex are a benign pathology commonly associated with ectopically placed teeth. Owing to slow and asymptomatic growth, they often attain considerable size before diagnosis that may compromise adjacent anatomical structures. Various techniques for removal of dentigerous cysts from the maxillary sinus have been described. This case report demonstrates a hybrid endoscopically assisted modification of the Caldwell-Luc approach to provide the technical advantages of both techniques.

Bacterial biofilms in patients with chronic rhinosinusitis

The possible presence of biofilms was examined in mucosal specimens of 15 patients, undergoing functional endoscopic sinus surgery or a modified Caldwell-Luc approach for chronic rhinosinusitis (CRS). Biofilms were found in 7 of the 15 patients, positive cultures being obtained in most samples, which supports the role of biofilms as an important factor in the pathogenesis of CRS.

Utilization of the Foley catheter in midfacial fracture reduction

Of all the techniques recommended for reducing fractures of the zygomaticomaxillary complex, we have found the one proposed by Jarabak 7 to be superior in our hands. This technique employs the use of an inflated Foley French catheter inserted into the sinus by way of a modified Caldwell-Luc approach. Its advantages over antral gauze packing have been presented. We have employed this technique in twenty-nine cases since January, 1968, with excellent results and no complications.
