Modified frontonasal sinus flap surgery in standing horses: surgical findings and outcomes of 60 cases.
Abstract: Previous studies of sinus surgery on standing horses have been based on techniques which utilise powered hand bone saws and preserve the bone flap, which was thought to be essential for a good cosmetic result. This report describes a simplified technique applied to the standing horse where the sinus flap construction used a large skull trephine and where the bone flap is necessarily discarded. Objective: To assess whether the modified standing frontonasal flap (SFF) surgery offers an effective method to investigate and/or treat sinunasal disorders in the horse. Methods: The case records of 60 horses subjected to modified SFF surgery were reviewed to analyse the efficacy of the technique when applied to a range of sinunasal disorders in terms of diagnosis, surgical findings, complications and long-term outcomes, including cosmetic effect. Results: Resolution of clinical signs was achieved in 54 out of 60 horses, and for the remainder the SFF technique proved useful on a diagnostic basis. The cosmetic result was, in the opinion of the owners, excellent or satisfactory in 48 of 56 (86%) horses. Conclusions: The modified SFF technique was found to be practicable and provided satisfactory exposure of the sinus contents for diagnosis and removal of diseased tissue in a range of disorders. An acceptable cosmetic result can be obtained in the majority of horses despite rejection of the disc of overlying bone. Apart from avoiding the risks associated with general anaesthesia, the advantages of the modified SFF sugery are: a reduction of haemorrhage in the standing horse; reduced mucosal engorgement; straightforward anatomical orientation; a comfortable working height; and reduced surgery time. A sound knowledge of the functional anatomy of the area is a prerequisite before embarking on any form of sinunasal surgery. Complications are infrequent and usually transient. Conclusions: The modified SFF technique is a valuable alternative to other invasive methods of sinunasal surgery.

The researchers studied a modified version of standing frontonasal flap (SFF) surgery used on horses to investigate and treat sinunasal disorders. They found that the technique was effective, reduced surgery time, and achieved satisfactory results in a majority of the cases, even with the discarding of overlying bone.
Objective and Methodology of the Research
- The researchers aimed to assess the effectiveness of a simplified version of standing frontonasal flap (SFF) surgery on horses undergoing sinus treatments.
- The original version of the technique involved the use of powered hand bone saws and preserving the bone flap for cosmetic reasons. The modified surgery, however, involved the use of a large skull trephine and discarded the bone flap.
- To study the efficacy of this method, the researchers reviewed case records of 60 horses that underwent the modified surgery. They analyzed the results based on various factors like diagnosis, surgical findings, complications, long-term outcomes, and cosmetic effect.
Results of the Research
- The researchers found that the clinical symptoms resolved in 54 out of the 60 cases they studied.
- In the remaining cases, the surgery served as a useful diagnostic tool.
- Despite the discarding of the bone flap, the owners of the horses found the cosmetic results of the surgery to be satisfactory or excellent in 48 out of 56 cases (86%). This counters the earlier assumption that preserving the bone flap is essential for an acceptable cosmetic result.
Conclusions and Advantages of the Modified Technique
- The researchers concluded that the modified SFF technique is a practical alternative that provides sufficient exposure of sinus contents for diagnosis and removal of diseased tissue.
- The surgery offers some key benefits, such as avoiding the risks related to general anaesthesia, reducing blood loss during operation, simpler anatomical orientation, and reducing the time needed for the surgery.
- Though a comprehensive understanding of the functional anatomy of the surgery field is necessary before attempting any form of sinunasal surgery, with proper knowledge, complications are rare and usually temporary.
