Mucopyocele: An Entity Infrequently Reported as a Complication of Functional Endoscopic Sinus Surgery

Area of Science:

• Otolaryngology
• Surgical Complications
• Rhinology

Background:

• Paranasal sinus mucoceles are uncommon complications following functional endoscopic sinus surgery (FESS).
• Risk factors for mucocele development include higher preoperative Lund-Mackay scores, inadequate post-operative management, and infrequent follow-up appointments.
• These mucoceles can arise after surgery for conditions like nasal polyposis and chronic rhinosinusitis with nasal polyposis.

Purpose of the Study:

• To report a case of bilateral fronto-ethmoidal mucocele secondary to FESS.
• To discuss the management of this specific case.
• To provide a brief review of the relevant literature on post-FESS mucoceles.

Main Methods:

• Case report detailing the occurrence of bilateral fronto-ethmoidal mucoceles post-FESS.
• Review of clinical presentation, diagnostic findings, and treatment strategies.
• Literature search for similar cases and risk factors.

Main Results:

• A case of bilateral fronto-ethmoidal mucocele successfully managed after FESS is presented.
• The study highlights the association between preoperative Lund-Mackay scores, post-operative care, follow-up frequency, and mucocele risk.
• Literature review supports the infrequent but potential occurrence of mucoceles post-FESS.

Conclusions:

• Functional endoscopic sinus surgery can rarely lead to the development of paranasal sinus mucoceles.
• Vigilant post-operative care and regular follow-up are crucial in mitigating the risk.
• Early recognition and appropriate management are key for favorable outcomes in post-FESS mucoceles.
