Choanal atresia is an uncommon condition with an incidence of 1:5,000-8,000 live births, affecting females more frequently and often associated with other malformations. This case report presents a 42-year-old female patient who was born with bilateral choanal atresia and intervened surgically for the first time at birth. However, the formed orifice was reobstructed a few months afterward, necessitating reoperation in adulthood. The purpose of this case report is to describe bilateral choanal atresia in detail, including its clinical presentation, epidemiology, diagnosis, pathogenesis, and therapeutic approach. It aims to enhance understanding of this rare but significant condition.

UNASSIGNED: This report details the unusual presentation of two hidden cavernous hemangiomas in the orbital apex, initially appearing as one tumor. The rarity and diagnostic complexity of this case underscore the need for meticulous surgical exploration and verification in orbital apex tumors.
METHODS: A physical examination of an elderly male with a three-year history of headaches revealed a space-occupying lesion in the left orbital apex. Imaging confirmed a tumor in the extraconical space above the optic nerve. Initial nasal endoscopy removed an orbital apex tumor, pathologically confirmed as a cavernous hemangioma.
UNASSIGNED: Postoperative examination revealed incomplete tumor removal, prompting a second surgery for full excision. This case underscores the diagnostic and management challenges of orbital apex tumors, especially when imaging indicates a single mass. The endoscopic transsphenoidal approach for cavernous hemangiomas in the medial orbital apex, as illustrated in this case, appears promising.
CONCLUSIONS: Clinicians must be aware of the potential for multiple tumors in orbital apex cases, even if imaging does not explicitly reveal them. This case highlights the importance of thorough surgical exploration and illustrates the effectiveness of endoscopic methods in intricate orbital apex surgeries.

UNASSIGNED: Recently, a novel purely synthetic topical haemostatic agent (PuraStat®) has been proposed in surgery based on the self-assembling tendency of some repeating peptide sequences. This transparent, ready to use hydrogel appears suitable for use in FEES with low rates of post-operative re-bleeding and adhesion formation.A first series of 60 patients experiencing endonasal powered turbinoplasty across various hospitals in Sydney using PuraStat® was observed for postoperative re-bleeding and adhesion formation.
UNASSIGNED: In all 60 patients, no post-operative re-bleeding was observed, while healing went well in absence of adhesion formation. Effective haemostasis with PuraStat® is well documented in other surgical fields, but its use in FEES and adhesion prevention is relatively novel.
UNASSIGNED: Synthetic self-assembling peptides appear to be indicated in this area. Further studies are needed to confirm their potential for adhesion prevention.
