The role of the osteoplastic flap in the endoscopic era: a retrospective multicentre experience on revision surgery.

Objective: To retrospectively review the experience of five tertiary-care university hospitals on frontal sinus revision surgery with osteoplastic flap (OPF). Methods: Descriptive analysis of patients who underwent frontal sinus surgery with OPF after one or more endoscopic procedures for benign and inflammatory pathologies from 2000 to 2022. Clinical charts were reviewed for demographics, indications, clinical presentation, previous frontal procedures, OPF technique and outcomes. Results: Of the 124 patients who underwent an OPF procedure, 33 met inclusion criteria. With a mean of 2.1 previous endoscopic surgeries, Draf III was the most common former procedure. In 30 (91%) cases OPF was part of a combined procedure. The most common indications were inverted papilloma (61%), mucocele (9%) and chronic rhinosinusitis (6%). Frontal outflow stenosis (36%) and mucocele (9%) were the most frequent complications observed. Improvement of overall symptoms and patient satisfaction after the OPF procedure were recorded. Conclusions: Even in the endoscopic era, OPF still represents a paramount procedure that should be included in the rhino-surgeon's armamentarium, in particular in patients with challenging pathologies and anatomy when previous endoscopic endonasal attempts have failed.

An easy method for intraoperative confirmation of lacrimal sac patency in endoscopic dacryocystorhinostomy.

PURPOSE: Few studies have focused on the intranasal localization of the lacrimal sac during endoscopic dacryocystorhinostomy: landmarks in order to find the medial wall of the lacrimal sac have been described, but there is a lack of description of methods for the verification of the complete marsupialization of the lacrimal sac during surgery. In this report, we propose an easy and effective method for certain intraoperative identification of lacrimal sac. METHODS: A method in order to verify the effective marsupialization of the lacrimal sac is applied and described: to ensure that the opening of the sac in the nasal cavity is complete, the surgeon should identify the Rosenmuller valve, which is the end of the common canaliculus in the lacrimal sac. Continuous irrigation with saline solution through the inferior canaliculus can be useful to obtain a clean surgical area and to permit easy intraoperative identification of the valve. RESULTS: Between 2007 and 2015, 193 endoscopic dacryocystorhinostomies were performed in our institutions. Postoperative surgical success at last follow-up (minimum 12 months) was 93.8% (181 out of 193 of cases). No major complications were observed. CONCLUSIONS: Correct and complete exposure of the lacrimal sac during surgery is crucial for a good outcome: when the opening of the common canaliculus is identified, the surgeon is assured that the sac has been correctly and completely marsupialized inside the nasal cavity.

Haemorrhagic presentation of a craniopharyngioma in a pregnant woman.

Objective. Craniopharyngioma is a rare tumour, and, consequently, acute clinical presentation and diagnosis, during pregnancy, of this pathology are quite difficult to find. Only few cases are reported in the literature, and no one describes these two conditions in association. Methods. We report a particular case of craniopharyngioma presenting both of the above conditions. Results. The patient was successfully operated with endoscopic technique. Conclusions. Rare and difficult cases, created by the superposition of different clinical conditions, need multidisciplinary management, with collaboration, integration, and cooperation between different medical specialists.

A unique case of multiple sites of pneumatization of the sinonasal bony framework in a pediatric patient.

Anatomic variations of the sinonasal bony framework in the pediatric population are quite common. In children with such variations, however, bony pneumatization is uncommon. Moreover, pneumatization of the inferior turbinate in children is extremely rare; to the best of our knowledge, only 3 cases have been previously reported in the literature-none of which involved additional pneumatization variations of the sinonasal skeleton. Herein we present a new pediatric case that was unique in that an inferior concha bullosa coexisted with rarely seen pneumatized anatomic structures.

Removal of a fronto-ethmoidal osteoma using the sonopet omni ultrasonic bone curette: first impressions.

Endoscopic exeresis of sinonasal osteomas usually implicates the use of surgical drills with some disadvantages, as underlined by many authors. A new device that performs an ultrasound bone emulsification has been proposed in recent years for bone removal in various surgical disciplines. In this case report, we present the first clinical ENT experience with this device in removing a fronto-ethmoidal osteoma, and we briefly discuss our impressions.
