Although nasal function outcomes and the results from SNOT-22 questionnaires were favourable, a high rate of neurologic and lacrimal complications was observed. Potential morbidity of the intervention, including the possibility of negative aesthetic sequelae, should be discussed during preoperative counselling.

SUMMARY Inverted papilloma of the frontal sinus is a challenging disease. Given its rarity, only small case series are present in the literature. The objectives of the present study are to review our experience in the surgical management of inverted papillomas involving the frontal sinus and to propose a practical algorithm for selecting the most appropriate approach. Data on patients affected by inverted papilloma involving the frontal sinus and surgically treated between 2002 and 2016 were collected. The type of involvement of frontal sinus and extent of surgery performed (endoscopic endonasal, external or combined approaches) were analysed. A brief review of consistent literature was also carried out. Forty-seven consecutive patients were treated using an exclusive endoscopic endonasal approach (EEA) in 18 cases, while a combined endonasal with external osteoplastic approach was required in 29 cases. Most patients (29/47, 62%) had been treated previously, mainly by an endoscopic approach. A single intraoperative complication occurred (1/47, 2%), i.e. cerebrospinal fluid (CSF) leak, that was successfully repaired intraoperatively without any consequences. Recurrences were observed in only 2/47 cases (4%) after a mean follow-up of 43 months (range, 12-137). The management of inverted papilloma involving the frontal sinus requires great expertise and the surgical technique should be tailored to the site of attachment of the tumour, its extension and the anatomical conformation of each frontal sinus. The encouraging results obtained in this case series support the use of this practical treatment algorithm.

The mainstream of treatment of early-stage oral tongue squamous cell carcinoma (OTSCC) is represented by transoral resection with "adequate" free margins. Despite that, a precise and shared definition of "adequate margin" is lacking, and so is a standardized transoral surgical technique.The tongue is a symmetrically paired organ, consisting of intertwining intrinsic and extrinsic muscles, which can be distinguished during dissection. Routes of tumoral spread in oral tongue cancer are well-known and should be taken into account during resection. We propose herein a standardized and replicable surgical technique to resect early-stage OTSCC, based on rational anatomical considerations.
