Combined Aplasia of Frontal and Sphenoid Sinuses: A case report.
Article in International journal of surgery case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introduction and importanceThe paranasal sinuses are a group of four paired air-filled spaces located within the bony skull; maxillary, frontal, sphenoid, and ethmoid sinuses. Paranasal sinuses aplasia is a rare condition that is mainly confined to the frontal sinus unilaterally. Combined aplasia of multiple sinuses along with hypoplasia of other sinuses is extremely rare. This rare case should be considered in mind before scheduling any endoscopic sinus surgery to prevent complications during these surgeries. CASE PRESENTATION: A 13-year-old male patient presented to our ENT clinic complaining of a prolonged history of persistent headache, nasal obstruction, and nasal discharge. He also complained of bilateral ears fullness and facial pain. On physical examination, bilateral purulent nasal discharge with congested inflamed nasal mucosa and both inferior turbinate. The patient was diagnosed to have sinusitis and was started on treatment. The patient returns to our clinic after several weeks with minimal improvement. Computed tomography (CT was obtained and showed completely absent pneumatization of bilateral frontal and sphenoid sinuses. CLINICAL DISCUSSION: The development of the paranasal sinuses appears prenatally which can lead to a variety of PNS anomalies. However, the aplasia or hypoplasia of the PNS is found to be rare. Aplasia is mainly found in frontal and maxillary sinuses with a prevalence of 12 % and 6 %, respectively. While the prevalence of sphenoid sinus aplasia is extremely rare and found to be less than 0.7 %. Moreover, aplasia of multiple sinuses "combined aplasia" is an incredibly unusual finding.
conclusionthis patient is one of the extremely rare cases of the combined aplasia of frontal and sphenoid sinuses who was diagnosed and confirmed at an early age without any skeletal, systemic, or hematological abnormalities. Despite that, this rare case should be considered in mind before scheduling any endoscopic sinus surgery to prevent complications during these surgeries.
